eng
This investigation was carried out to study the effect of temperature resulting from different planting dates during the stage of vegetative growth and the effect of genotypes x environment interaction on forage yield and its components in some varieties of berseem clover (Trifolium alexandrinum L.). A set of six varieties (Serw-1, Gemmeiza-1, Giza-6, Sakha-4, Helally and Local variety) were sown on four planting dates (September 15th, October 15th, November 15th and December 15th) in randomized complete block design with four replicates in experimental farm of Assiut University during 2014/2015 and 2015/2016 seasons. Three cuts were taken after 70, 110, 145 days from sowing. The results showed that the planting dates and varieties had a significant differences for plant height leaf/stem ratio, seasonal fresh and dry forage yields in both seasons and over the two seasons. Also, the tallest plant height was obtained from the plants sown on 15th October in both seasons. Serw-1 variety significantly gave the tallest plant height over planting dates. Moreover, the highest leaf/stem ratio was obtained from the planting date at September 15th in both seasons. Otherwise, leaf/stem ratio decreased gradually and reached to the minimum value at the December 15th in both seasons. Local variety gave the highest leaf/stem ratio.
The seasonal fresh forage yield significant decreased as planting date was delayed. Helally variety produced the highest seasonal fresh forage yield over the two seasons. Meanwhile, the seasonal dry forage yield increased as planting date was delayed. No significant differences were noticed in seasonal dry forage yield among commercial varieties (Serw-1, Gemmeiza-1, Giza-6, Sakha-4 and Helally). In the same the trend, the environments, varieties and their interaction were significant for plant height, leaf/stem ratio and seasonal dry forage yield.
Finally, the stability analysis revealed that the average stability region involved Gemmeiza-1, Giza-6, Local variety and Serw-1 varieties for plant height, Gemmeiza-1, Local variety and Serw-1 varieties for leaf/stem ratio and Gemmeiza-1 and Helally varieties for seasonal dry forage yield.

Tolerance of Egyptian Cotton Varieties (G. barbadense L.) to Late Planting
text
article
2017
eng
This study was done to evaluate two sets of Egyptian cotton varieties (G. barbadense L.) for tolerance to late planting. The first set included 16 cultivated and obsolete varieties which evaluated for two seasons under early and late plantings. The second set included eight varieties selected from the first set for tolerance to late planting; four susceptible and four tolerant, and evaluated for three seasons. In the first set, mean squares of all the studied traits indicated significant (p ≤ 0.01) differences among varieties in separate and combined analyses under early and late plantings. Also, the combined analysis showed significant (p ≤ 0.01) differences between dates for all traits. However, the interactions of varieties × dates and varieties × dates × years were not significant. The mean square of varieties × years was significant only for lint percentage, boll weight and days of first flowers. Furthermore, the interaction mean squares of varieties x years under both of early and late planting was not significant indicating that the different traits were stable from year to year either for early or late planting. Late planting caused severe reduction in seed cotton yield reached 19.28, 19.14 and 19.21 % in the first, second year and combined date. Stress susceptibility index varied slightly from year to year. The highest stress susceptibility index was recorded for the varieties Giza 81 and Menoufi (1.19) followed by Giza 85 (1.20), Giza 88(1.20), Giza 69 (1.15), Giza 95 (1.15), Ashmouni (1.10) and Giza 92 (1.04). The highest yielding varieties (G90× Aus, Giza 90, Dandara, Giza 86 and Giza 80 were tolerant to late planting and scored stress susceptibility index less than unity. The highest varieties in lint yield were G90× Aus, followed by Giza 90, Giza 80, Giza 86 and Giza 95 under both planting dates. The reduction % in lint yield caused by late planting was very high and larger than that in seed cotton yield, and reached 22.88, 22.56 and 22.72 in the first, second year and combined data, respectively. The stress susceptibility index of the different varieties respect lint yield / plant showed the same picture as seed cotton yield /plant. The reduction in lint% for different varieties was low and averaged 4.53, 4.41 and 4.47 % in the first, second season and combined means, respectively. The reduction % in boll weight caused by delaying planting data was high and reached 21.79, 20.85 with an average of 21.31 %. The reduction% in boll weight was more than that in seed cotton yield. Therefore, number of bolls /plant increased under late planting. These results indicate that the stress of delay planting shortened the vegetative period of cotton growth. The results of the second set of varieties were in the same trend of the first one. These results indicate that the main cause of reduction in cotton yield is late planting date. This is due to that all the Egyptian cottons were bred to grow under full season and not for short season conditions. However, the stress susceptibility index indicated to the presence of tolerant varieties to late planting, and there is a chance to select for short season condition from the progenies of the crosses of such tolerant varieties.

A Study of Phenotypic and Genotypic Correlations and Path Analysis of Seed Cotton Yield Components in Egyptian Cotton Varieties (G. barbadense L)
text

2017
eng
Two sets of Egyptian cotton varieties were evaluated under early and late plantings. The first set included 16 cultivated and obsolete varieties and were evaluated for two seasons at Assiut Univ. Exper. Farm. The second set was selected from the first one; four varieties tolerant to late planting and four susceptible. The second set of varieties was evaluated in the third season at Shandaweel Res. Stn. Cott. Res. Ins. ARC. The combined analysis of variance of each set indicated insignificant interaction of years × dates, years × varieties and years × varieties × dates. However, the main effects of dates and varieties were significant (p ≤ 0.01). The genotypic and phenotypic correlations were estimated among seed cotton yield / plant, lint yield / plant, boll weight, number of bolls / plants and seed index. Phenotypic and genotypic correlations coefficients were very close and sometimes similar. Under early planting of the first set of varieties; lint yield / plant showed the highest genotypic correlation (0.989) with seed cotton yield / plant followed by number of bolls / plant (0.856) and boll weight (0.296). However, the genotypic correlation of seed index with seed cotton yield / plant was very small (0.042). The results indicated negative correlation between number of bolls and boll weight. The phenotypic and genotypic correlations under late planting and for the second set of varieties showed nearly the same trend. The study of path analysis in the two sets of varieties under early and late plantings indicated that lint yield / plant mostly showed the large direct effect on seed cotton yield, and when its direct effect was negative, it affected seed cotton yield via number of bolls and boll weight. The direct effect of number of bolls / plant on seed cotton yield / plant was high, and followed by boll weight. The results revealed that simultaneous selection based on lint yield / plant, number of bolls / plant and boll weight could be promising to breakthrough in seed cotton yield / plant.

One of the most important advantages of intercropping or sowing methods is to get the highest yield on a specified area of land through using more efficient way of the available resources. Two successive winter field experiments were conducted at Sakha Agricultural Research Station, Agricultural Research Center (A.R.C), Kafr El-Sheikh Governorate, Egypt, during 2014/2015 and 2015/2016 growing seasons in a split plot design with three replications to study the effects of three different sowing methods viz. flat, terraces and rows; main plots in addition to three different mixed intercropping treatments of Egyptian clover var. Fahlwith wheat (10, 15 and 20% of recommended seeding rate for Egyptian clover var. Fahl(i.e. 20 kg fed-1) with 100% of recommended seeding rate of wheat [60 kg fed-1]; sub plots). In addition, the two crops were sown as pure stand cultivation in a flat sowing method. Results showed that sowing method of terraces and intercropping Egyptian clover var. Fahlby 10% with 100% wheat resulted in the highest improvement of growth and yield and its components in addition to the highest crude protein content in comparison to the other sowing methods and intercropping patterns. However, the pure stand of wheat had the highest values of grain yield fed-1 and its components in comparison to intercropping treatments. The highest LER (land equivalent ratio; 1.30 and 1.29) and the highest total income (12034 and 11899 L.E.) were obtained when wheat was sown on terrace and intercropped with 10% of Egyptian clover var. Fahlin both of seasons, respectively. In conclusion, sowing method of wheat on terraces and intercropping 10% of Egyptian clover var. Fahlwith wheat could be the appropriate suggestion for farmers in North Middle Nile Delta region, Egypt.

Evaluation of Irradiated Okra based on Agronomical Traits and RAPD Markers
text
article
2017
eng
This study was conducted on three inbred lines of okra Abelmoschus esculents (C8, C9 and Cr) obtained from the Horticultural Research Institute, Agricultural Research Center. Seeds were irradiated with gamma rays at doses 10, 20 and 30 Kr. This study aimed to evaluate the effect of ionizing radiation on molecular and phenotypic levels, using RAPD six out of 19 RAPD primers were succeeded in generating reproducible polymorphic amplicons among all irradiated plants and their control on each inbred line. All irradiated plants of soaked seeds showed the highest unique markers (21) compared with irradiated dry seeds which showed 11 unique markers. This indicated that gamma irradiation was effective for inducing higher rate of mutations in the soaked seeds. On the other hand, C8 gave the highest number of unique markers (10 negative and 4 positive). While, C9 displayed the highest percent of polymorphic amplicons (81.4%) and it was the only genotype which increased in number of complementary sites with RAPD primers by irradiation treatments. Furthermore, other genotypes decreased in number of complementary sites with RAPD primers by treatments. Moreover, the correlation between molecular and phenotypic distances was positive and highly significant (r= 0.645) in Cr only, which may be explained that 73.3% for Cr of amplicons were polymorphic from the genome areas which coded for studied traits. So, it is possible to reliance on the unique markers for this inbred line as markers assisted selection for the improved traits due to irradiation. In addition, Cr was the best in response to genetic improvement % by irradiation, especially 20/S treatment which led to significant improvement of yield and some of it’s component traits. The improvement percent, ranged from 21.4 to 152.0 % for number of leaves per plant (Nl/p(, number of fruits/plant (Nf/p), number of seeds per pod (Ns/pod) and fruit yield per plant (FY/p) traits, was highly expected to be associated with four molecular markers. These markers were three negative and one positive (485bp targeted by OP-A02 primer), which could be used as markers assisted selection to improve yield and its components in breeding programs and improvement of okra.

Response of Night-Blooming Jessamine (Cestrum nocturnum L.) Plants to Phosphorus-Zinc Relation. 1-Growth, Flowering and Uptake of Phosphorous and Zinc.
text
article
2017
eng
Night blooming jessamine (Cestrum nocturnum L.) plants were grown in pots to study P-Zn relations as the behavior of both P and Zn affecting the absorption of each other by the plant that reflect on growth and flowering. Phosphorus was applied to soil at rates of 0 to 560 ppm with addition of Zn at rates of 0 to 48 ppm.
Greatest plant height, branch number, flowering (earliness and duration) and maximum dry weight accumulation in the different plant parts were occurred by the combination of 280 ppm P and 24 ppm Zn applied. In the absence of added P, shoot/root ratio was increased with increasing Zn level up to 24 ppm. Phosphorus at 70 and 560 ppm with Zn levels, this ratio was a nearly constant, while P at 140 and 280 ppm with low Zn level added, the ratio was decreased.
Total uptake of P and Zn indicated that P and Zn fertilization had altered the uptake of both nutrients by the plant. Total uptake of P was increased by high P and low Zn. Total Zinc uptake varied opposite to that of P. The maximum of P and Zn were obtained by P280 Zn24 as the greatest growth and flowering occurred.

eng
Night blooming jessamine (Cestrum nocturnum L.) plants were grown in pots to study P-Zn interactionwhich influence on their accumulations and other micronutrients in leaf tissue. Phosphorus fertilization was applied to soil at rates of 0 to 580 ppm with concomitant addition of Zn at rates of 0 to 48 ppm.
Concentrations of Zn, Fe and Mn in leaf tissue indicated that P and Zn fertilization had altered the accumulation of these micronutrients in the plant. Although P and Zn application decreased the concentration of each other, increasing either P or Zn applied increased leaf Mn. Concentrations of P, Zn and Mn were varied opposite to that of Fe. Zinc-deficient plants accumulated a large excess of Fe. Interference from excess Fe is suggested as contributing to physiological malfunction within Zn-deficient night-blooming jessamine plants. High concentration of P in leaf tissue resulting in high P/Zn concentration ratios appear to offer a better explanation for the metabolic upset. Healthy plants tended to have P/Zn concentration ratios < 100, where in deficient plants the ratio was generally > 100.
Some of the resulting observations help to explain why starter fertilizers containing P may on occasions cause depressions in plant growth, especially when soil P is high, would seem to portend Zn deficiency problems as the behavior of both P and Zn in affecting translocation of each other.

Studies for Solving Late Maturation, Quality and Irregular Colouration Problem in Flame Seedless Grapes Grown Under Luxor Climatic Conditions
text
article
2017
eng
During 2015 and 2016 seasons clusters of Flame seedless grapevines grown under Luxor region conditions were subjected to Ethrel and/or Proton (10% ABA) each at 250 to 500 ppm with or without the application of acetic acid and phosphoric acid each at 2000 ppm. The merit was examining the effect of these materials on advancing maturation of berries and enhancing colouration and quality of the berries.
Treating the clusters with Ethrel and/or Proton (10% ABA) each at 250 to 500 ppm with or without the application of acetic acid and phosphoric acid was very effective in advancing maturation of the berries and enhancing berries colouration and chemical quality of the berries relative to the control treatment. Using Ethrel was superior than using Proton on advancing maturation and enhancing chemical quality of the berries. Moreover, using Ethrel plus Proton was favourable than using each alone in this respect.
The best treatment was exposing the clusters of Flame seedless grapevines to Ethrel and Proton (10% ABA) each at 250 ppm plus application of phosphoric acid at 2000 ppm once at veraison stage.

2017
eng
During 2015 and 2016 seasons, Superior grapevines were fertilized with N (60 g N vine/ year) as 25 to 100% inorganic N with or without foliar application of chicken manure tea at 10 to 40% and ascorbic acid at 500 to 2000 ppm. The target was elucidating the effect of using poultry manure tea and ascorbic acid as alternatives to chemical N fertilizer on fruiting of the vines.
Using N as 50 to 75% inorganic N plus spraying chicken manure tea at 10 to 20% and ascorbic acid at 500 to 1000 ppm was very effective in stimulating all growth aspects, berry setting %, yield and cluster weight and dimensions over the application of N via inorganic N alone at 25 to 100%. leaf chemical constituents and quality parameters were obviously enhanced on the vines that received N as 25% inorganic plus spraying chicken manure tea at 40% and ascorbic acid at 2000 ppm
For promoting the yield of Superior grapevines, it is suggested to use N as 50% inorganic N plus spraying chicken manure tea at 20% and ascorbic acid at 1000 ppm three times. For improving quality of the berries , it is advised to use N as 25% inorganic N + spraying poultry manure tea at 40% and ascorbic acid at 2000 ppm three times.

eng
During 2015 and 2016 seasons, Red Roomy grapevines were fertilized with three organic manures (Poultry manure, Plant compost and Farmyard manure) enriched with Spirulina platensis algae as a partial replacement of 25 to 75% inorganic N. The merit was detecting the best source of organic N enriched with Spirulina platensis algae applied with inorganic N that responsible for producing higher yield with better berries quality.
Replacing 50% of inorganic N by 50% organic manures enriched with Spirulina platensis algae at 20 ml/vine was enhancing growth, yield and cluster weight on the other hand replacing 75% of inorganic N by 75% organic manures enriched with Spirulina platensis algae at 40 ml/vine gave favourable effects on vine nutritional status, berries colouration and quality of the grapes. Percentage of shot berries was greatly declined by using N as 25% inorganic N plus 75% organic manures enriched with Spirulina platensis algae at 40 ml/vine. In descending order, the best organic manures in this respect were poultry manure, Plant compost and Farmyard manure.
For enhancing growth and yield of Red Roomy grapevines, it is suggested to supply the vines with N (60g/vine/year) through 50% inorganic N + 50% poultry manure enriched with Spirulina platensis algae at 20 ml/vine/year. Fertilizing the vines with N as 25% inorganic N + 75% poultry manure enriched with 40 ml Spirulina platensis algae gave the best results with regard to berries colouration and quality.

eng
The present investigation was carried out during 2013, 2014 and 2015 seasons to study the effect of plant extracts on growth and fruiting of Flame Seedless grapevines. The experiment was arranged in a randomized complete block design in which the study involved seven treatments with three replications, two vines each.
Pruning wood weight, leaf area and leaf chlorophyll were significantly increased by spraying either garlic, turmeric or roselle extracts compared to unsprayed ones. Spraying garlic, turmeric or roselle extracts were very effective in improvement the yield/vine and cluster traits. Moreover, these treatments significantly improved the berry quality in terms of increasing the berry weight, total soluble solids and anthocyanin in skin of berries compared to unsprayed ones. The best results were obtained on the vines that sprayed with 0.2% turmeric extract. No significant differences were obtained among the tested extract. It could be concluded that spraying turmeric, roselle or garlic extract at 0.1% three times annually was necessary to get high yield with good cluster and berry quality of Flame Seedless grapevines.

An Analytical Study of the Impacts of the Investment Policy on the Egyptian Agriculture in the Period Between 1990-2015
text
article
2017
eng
The agricultural development is based on many foundations. One of the most important of these foundations is the capital accumulation in the agricultural sector, though the targeted annual investment can develop this sector vertically and horizontally. Therefore, it is necessary to study the investment policy and its impacts on the agricultural policy, especially during the world financial and economic crisis that has impacted the Egyptian economy in general, and the agricultural sector in particular. The relative importance of the agricultural investment as a percentage of the total national investment declined from about 5.02% in 2010/2011 to 4.05% in 2011/2012, which was the year before the world financial crisis. This declining continued and reached 3.67% in 2013/2014, the first year of the world financial crisis. This led in return to decline the contribution of the agricultural sector in the GDP from 13.85% in 2011/2012 to about 13.21% and 12.81% in the two years of the world financial crisis, respectively. This situation underlines the importance of this research, which aimed to analyze the investment policy in Egypt using the investment relation and the most important factors assigned to them.
The results of the investment function have shown that an increase of the national income in the current year with one million pounds led to an increase of the total investments with 0.127 million pounds, while an increase of the national income in the previous year with one million pounds led o increase the investment of this year with 2.11 million pounds. Also, the decreasing of the interest rate with one unit led to increase of the investment with 3.6 million pounds. The results of the Klein model have shown that the national consumption function is statically significant at 0.01 level, where the coefficient of determination shows that about 92% of the changes in the national consumption are due to the change of the national income in the current year and in the previous year and of the employment’ wages in the current year. While the rest of changes is due to changes of other factors not covered in the model. Results of the research its shows inceasing gross agricultural products at an annual rate statistically significant reached about 3.7% and deacreasing gross investment an annual rate statistically significant reached about 0.7% during studing period although increasing gross agricultural investment at an annual rate reached about 1.08%, 1.12% during studing of two periods and decreasing agriculral investment productivity coefficient in general during period 00/2001 – 14/2015 and decreasing profitability investor pound in the agricultural sector and decreasing investment affecientcy in the same sector did not exceed agricultural investment the value of the agricultural product through studing two periods although increasing agricultural saving average propensity to agricultural save and raising rate of covering agricultural save to agricultural investment which led to imbalance between them. This is due to agricultural savings directed to non- agricultural investments. It has also been showed that increased national income leads to increased national investment and thus increased total agricultural investment there was also an inverse relationship between the intrest rate and the increase in local agricultural investments.
