These experiments were conducted to study the probability of using clean agriculture to produce organic cotton and reduce environmental pollution. A randomized complete block design with 4 replicates was used in both seasons, where the following twelve patterns were evaluated with regard to growth and its attributes of the Egyptian cotton (Gossypium barbadense, L.), cultivar Giza 86:- Patterns 1, 2, 3 and 4 included two rates of mineral NPK fertilizers (45 kg N: 22.5kg P2O5 :24 kg K2O /fed  (the recommended rate) and 60 kg N :30 kg P2O5 : 36 kg K2O /fed) in combination with chemical or bio- control, respectively. Patterns 5, 6, 7 , 8, 9,10, 11 and 12  included two rates of organic NPK fertilizers (45 kg N: 22.5kg P2O5 :24 kg K2O and  60 kg N :30 kg P2O5 : 36 kg K2O /fed) in the form of pigeon refuse as source of N in Patterns 5, 6, 7 and 8 and in the form of phytocompost in Patterns 9, 10, 11 and 12 +  in the form of phosphate ore  (20 % P2O5) +Phosphorein  as source of P +  in the form of potassium ore (8.2 % K2O)as source of K in Patterns 5, 6,  9 and 10, in combination with bio- control. In patterns 7, 8, 11 and 12 the source of P was mixed minerals ore (6.14 % P2O5) +Phosphorein and the source of K was mixed minerals ore (3.37 % K2O) and potassium ore, in combination with bio- control. The obtained results could be summarized as follow:- Leaf area index and total dry weight per plant were significantly affected by the tested Patterns at all sampling dates in both seasons, in favor of Pattern 8( high organic NPK rate, where the source of N was  pigeon refuse, the source of P was mixed minerals ore +Phosphorein  and the source of K was mixed minerals ore and potassium ore in combination with bio-control) and Pattern 6 ( high organic NPK rate, where the source of N was  pigeon refuse, the source of P was phosphate ore +Phosphorein  and the source of K was potassium ore in combination with bio- control). Crop growth rate and net assimilation rate were significantly affected by the tested Patterns at the first and second periods in both seasons, in favor of applying Pattern 8 and pattern 6 at the first period in the first season and at the first and second periods in the second season. In addition, these two Patterns gave the tallest plants with the highest number of fruiting branches, while the shortest plants with the lower number of fruiting branches produced from Pattern 9 (low organic NPK rate, where the source of N was phytocompost, the source of P was phosphate ore +Phosphorein and the source of K was potassium ore in combination with bio- control) in both seasons.               The high mineral NPK fertilizers rate when combined with chemical control (Pattern 2) or bio-control (Pattern 4) significantly increased leaf area index at 79 days from sowing in the first season and at 100 and 121 days from sowing in the second season. Also, these two Patterns significantly increased total dry weight per plant at the three sampling dates and crop growth rate at the first and second periods in both seasons and net assimilation rate at the second period in both seasons and produced the tallest plants with the highest number of fruiting branches and highest internodes number per plant as compared with the recommended rate either with chemical control (Pattern 1) or bio-control (Pattern 3). Insignificant differences in traits under study were found when using the high mineral NPK fertilizers rate either with chemical control (Pattern 2) or bio-control (Pattern 4) or using the recommended rate either with chemical control (Pattern 1) or bio-control (Pattern 3) which indicate that biological control was effective. The high organic NPK rate significantly increased leaf area index and total dry weight per plant at 79, 100 and 121 days from planting in 2012 and 2013 seasons and crop growth rate and net assimilation rate at the first and second periods in both seasons and gave the tallest plants with the highest number of fruiting branches as compared with the low organic NPK rate especially when the source of N was pigeon refuse, the source of P was mixed minerals ore  + Phosphorein  and the source of K was mixed minerals ore and potassium ore in combination with bio- control (Pattern 8) or when the source of N was  pigeon refuse, the source of P was phosphate  ore + Phosphorein  and the source of K was potassium ore in combination with bio- control ( Pattern 6).

Fifteen  treatments were arranged in split plots design, which were the simple possible combination between three treatments of soil application (Straw rice costs (4 ton/fed.), Humic acid (5 kg/fed.), and Polymers (20 kg/fed)) and five foliar treatments of ( (tap water), Ca (calcium citrate 2.5 mg/L) + B (boric acid 1.5 mg/L), Yeast (10 mg/L) + K (potassium citrate 2.5 mg/L), Yeast (10 mg/L) + NAA (naphthalene acetic acid 2.5 mg/L) + K (potassium citrate 4 mg/L) and Zn (0.35 gm/100 L) + Cu (0.20 gm/100 L) + Mn (0.25 gm/100 L) in sulphure form). Each treatment was replicated three times. Thus, the total numbers of plots were 45 plots plus control treatment. The NPK fertilizers were added to soil cultivated with pepper plants as recommended by the Ministry of Agriculture and Soil Reclamation. The seedlings of bell pepper (Capsicum annuum L.) were transplanted on 1st of April in 2012 and 2013, respectively, on two side of ridges at 30 cm a part.   Plant height, fresh weight, dry weight, leaf area, number of leaves, number of flowers and number  of branches were measured as vegetative growth parameters.

But, use of some seed treatment methods may be help to improve plant tolerance of salinity. Therefore, the objective of this study was to evaluate some seed treatment methods to alleviate the harmful effect of salinity on seed germination and seedling vigor of wheat (Triticum aestivum L.). Laboratory experiment, followed by pot experiment was conducted in 2013 year at laboratory natural conditions of Seed Technology Research Unit in Mansoura, Dakahlia Governorate, Field Crops Research Institute, Agricultural Research Center, Egypt. Seeds of wheat (cv. Miser 1) were treated with humic acid (in the form of Actosol) at the recommended concentration (5 ml-1water) for 12 hour by different methods (soaking, priming and dressing). Germination and seedling vigor under control (4 dsm-1) and saline (6, 8, 10, 12 dsm-1) conditions were studied to determine the usefulness of those methods in increasing relative salt-tolerance. Seedlings of treated seed of pot experiment sprayed with humic acid after 15 days from sowing.  The results showed that the best values of germination percentage, mean germination time, shoot length, root length and seedling dry weight were recorded when wheat seeds soaked in humic acid, followed by priming in humic acid solution. While, dressing seeds with humic acid method was the inferior one. Combination of soaking seeds and foliar application of seedlings with humic acid was more effective on seedling vigor as compared to soaking or priming seeds alone. The pre-sowing seed treatment which is an easy and low risk technique may be used as an alternative approach to alleviate agricultural salinity stress.}, keywords = {}, url = {https://jpp.journals.ekb.eg/article_49588.html}, eprint = {https://jpp.journals.ekb.eg/article_49588_528b9421531641562deacc9118f7df75.pdf} } @article { author = {Ismail, Sh. and Alian, F.}, title = {EFFECT OF SOME STIMULATION EMERGENCE TREATMENTS AND PLANTING DATES OF NURSERY ON ARTICHOKE (Cynara scolymus L.)

Two experiment were conducted  first experiment was carried out in nursery in which treated stumps were planted in nursery in two planting dates, June1stand July 1st and transplanting in field after 45 days after every planting date. Data were recorded in nursery; on plant high, leaves number, offshoots number and roots number ,roots length and survival percentage after 45 days from every planting date. Second experiment was conducted in field to subsequent plants treated until production of flower heads. Data recorded in field on survival percentage, early, and total yield per fed. as a number, number of heads per plant, quality parameters of flower head and edible part in both early and total yield. Dry matter and inulin concentration in edible part in early and total yield were also recorded. Obtained data in first experiment indicated that the second date (July 1st ) gave  increase significantly plant height after 45 days from planting. cooling and BA treatments affected  plant height significantly compared with all other treatments after 45 days. The best number of offshoots was obtained from the first planting date and there were no significant differences after 45 days .The highest number of offshoots were achieved by the cooling treatment all over stages of nursery growth. It was noted that there was no significant effect of planting dates on the number of leaves after 45 days after planting , Results indicated that both of BA, the bio- rooting and mycorrhiza treatments increased the number of leaves during the nursery stage. Results show that all the interactions between cooling, BA and bio rooting treatments had increased in all vegetative nursery growth in both planting dates. The bio rooting and mycorrhiza improved roots number in first planting date. While the BA was the best treatment for the root length in first planting date. Survival% of plants in the nursery was not affected by planting dates. The highest percentages of survival in nursery were obtained from the cooling ,BA and bio-rooting  treatments . The highest percentages of survival in field were obtained from the cooling and bio-rooting treatments in the second planting date. The second planting date gave the maximum number of head in early yield, also BA and bio-rooting treatments significantly influenced on early head yield and its quality. There were no significant effect of planting dates on the total yield and its quality. The cooling treatment improved significantly the total heads yield . But fresh weight of receptacles  increased significantly with the BA, IBA and mycorrhiza, while the diameters of heads and receptacles were affected by the cooling treatment. Also, late planting date (July 1st) significantly increased dry matter and inulin content in total yield. Three pre- treatments of nursery mycorrhiza, BA and IBA enhanced dry matter and inulin content in early yield .While, cooling treatment significantly increased dry matter and inulin content in total yield. It can be concluded that stumps were planted in nursery on June 1st and treated with BA, bio- rooting and cooling improved all vegetative growth parameters in nursery, while planting date in July 1st with the same treatments gave the maximum values of early , total yield and quality parameters , as well as dry matter and inulin contents in both early and total yield.}, keywords = {planting dates,nursery treatments,Cooling,BA,bio- rooting,survival % early and total yields}, url = {https://jpp.journals.ekb.eg/article_49591.html}, eprint = {https://jpp.journals.ekb.eg/article_49591_eeb604b39931de86c2eb470860623772.pdf} }
