Abees. The most important finding could be summarized as follows: In general, results showed that the plants sprayed with mixture of micronutrients were better than those of the unsprayed ones. Increasing the foliar applied mixture of micronutrients concentration from 0 to 50 ppm significantly increase plant height, plant dry weight and leaves area/plant as well as total yield, marketable yield and weight, length and diameter. Moreover, foliar application of mixture of micronutrients significantly increased concentrations of N in the first season only. In addition, reducing sugar and carotene were increased in both seasons. Foliar spray with mixture of micronutrients at 50 ppm had the most interesting observation in the enhancing of most studied characters. On the other hand, application of slow release nitrogen fertilizers rates gave rise to significant increases in plant height, number of branches/plant; plant dry weight, leaves area/plant ratio, total yield, marketable yield and weight, length and diameter as well as chemical and organic constituents on tuber root of sweet potato. The application of 60 kgN/fed. sulfur coated urea "SCU", was superior on all studied characters. The combined treatments of sprayed with mixture of micronutrients and sulfur coated urea "SCU" were generally more effective on the most studied parameters than single ones. The best results were obtained by foliar sprayed with micronutrients at 50 ppm and application with 60 kg N/fed. sulfur coated urea "SCU" gave the highest values of plant growth, yield and its components as well as chemical and organic constituents in both seasons compared with the other treatments. Therefore, this treatment could be recommended for raising sweet potato productivity and quality under similar conditions to this work. }, keywords = {Sweet potato,slow release N-fertilizers,sulfur coated urea,Micronutrients}, url = {https://jpp.journals.ekb.eg/article_51736.html}, eprint = {https://jpp.journals.ekb.eg/article_51736_cd7bfa48b28153246cc442bd7eadd3a6.pdf} } @article { author = {Gouda, A. and Gahwash, M. and Abdel- Kader, A.}, title = {RESPONSE OF POTATO GROWTH AND YIELD TO SOME STIMULATING COMPOUNDS.}, journal = {Journal of Plant Production}, volume = {6}, number = {8}, pages = {1293-1302}, year = {2015}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2015.51741}, abstract = {Two field experiments were carried out at the private Farm in Basandela Village, Belqas, Dakahlia Governorate during the two successive summer seasons of 2012 and 2013 to study the response of potato (c.v.

Split- split plot design with four replications was used. The main plots included three plant densities (168000, 144000 and 120000 plants/ fed), the sub plots included two soybean genotypes (Giza 111 and Toano).  Meanwhile, the sub-sub plots included six weed control treatments (prometryne at 1.0 L/fed; pendimethalin at 1.5 L/fed) plus one hand hoeing; (prometryne and pendimethan) followed by fluzifop-p-buty at of 1.0 L/fed, hand hoeing twice and unweeded control treatment. Results showed that increasing plant density reduced dry weight of broad- leaved, grassy and total weeds under combined, reduced dry weight of broad- leaved, grassy and total weeds by 26.4, 27.9 and 26.9%, to Toano. However, Giza 111 suppressed the growth of broad- leaved, grassy and total weeds by 28.7, 24.7 and 27.3%, respectively, and increased soybean seed yield by 6.67%. All weed control treatments reduced dry weight of broad-leaved, grassy and total weeds as compared with control treatment. Yield losses under control treatment were estimated by 39.66% as compared with prometryne/ one hand hoeing treatment. Seed yield (ton/fed) was positively correlated with yield components and negatively correlated with most weeds in combined analysis. Thus, weed control of soybean depended on weed control integrated in this crop. Whereas plant density reduced the weeds by 26.9%, genotypes by 27.3% and prometryne/one hand hoeing by 89.8%. Meanwhile, the integration between such factors as plant density, genotypes and weed control treatments reduced the weeds by 94.0%.}, keywords = {}, url = {https://jpp.journals.ekb.eg/article_51891.html}, eprint = {https://jpp.journals.ekb.eg/article_51891_ec073ac51e5f5ab2316ac82ce60521a2.pdf} } @article { author = {Abdel-Mohsen, M. and Kamel, H.}, title = {FRUIT SET AND QUALITY OF 'CANINO' APRICOT FRUITS AS AFFECTED BY SPRAYING WITH YEAST, GROWTH REGULATORS AND MICRONUTRIENTS}, journal = {Journal of Plant Production}, volume = {6}, number = {8}, pages = {1431-1441}, year = {2015}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2015.51895}, abstract = {This experiment was carried out during 2014 and 2015 seasons on 'Canino' apricot trees grown in sandy soil under drip irrigation system in a private farm at El-Bostan region in Behera  governorate, Egypt to study the effect of foliar spraying with Yeast (0.1 and 0.2%), Benzyladenine (50 and 100 ppm), GA3 (50 and 100 ppm), Boric acid (25 and 50 ppm) and flower power (2 and 4%) at full bloom stage on fruit set and fruit quality. Results showed that spraying 'Canino' trees with BA at 100 ppm followed by Boric acid (25 ppm) as well as GA3 (50 ppm) gave the highest significant fruit set in comparison to control. Fruit weight, volume, length, width and fruit flush weight were significantly increased as result of GA3 at 50 ppm, Flower power (4%) and GA3 (100 ppm) treatments respectively. Moreover, firmness of fruits obtained from BA at 50 ppm and Flower power at 4% treatments were significantly higher than control. The data also reveal that applied treatments had no significant effect on fruit shape index (L/W). Concerning the results of fruit kernel properties, it was noticed that, GA3 at 50 ppm, boric acid (25 ppm) and flower power (2%) treatments were more effective to enhance 'Canion' kernel properties. Treatments of BA at 100 ppm and Yeast at 0.1 % as well as Flower power at 4% increased SSC (%) and SSC/acid ratio. However, all treatments significantly decreased acidity percentage comparing with control fruits. It can be concluded that, most of the studied parameters were enhanced with foliar applications of GA3 at 50 ppm, BA at 100 ppm and Flower power at 4% at full bloom stage of 'Canino' apricot trees in comparison with control treatment.}, keywords = {Canino apricot,yeast,growth regulators,Micronutrients,fruit set,Fruits attributes,Kernel properties}, url = {https://jpp.journals.ekb.eg/article_51895.html}, eprint = {https://jpp.journals.ekb.eg/article_51895_b7a348d4cf287eebea0feb6849d81bc9.pdf} } @article { author = {Abdel-Mohsen, M.}, title = {COMPOST AS PEAT SUBSTITUTE IN OLIVE CUTTING MEDIA}, journal = {Journal of Plant Production}, volume = {6}, number = {8}, pages = {1443-1450}, year = {2015}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2015.51898}, abstract = {The possibility of replacement compost as peat moss in olive propagation media (PM) and it’s impact on growth was investigated during both 2013 and 2014 seasons.

Propagation media (Treatments) consist of: sphagnum peat-moss: sand in one ratio (1:3) as a control and plant composting: sand in five ratio (1: 3, 1: 4, 1: 5, 1: 6 and 1: 7) by volume. The obtained results clearly showed the enhancements in cuttings rooting percentage and root characteristics were associated with the highest sand compost ratio (1: 6 or 1:7) as well as peat: sand media (1:3) which correlated with decreasing bulk density and penetration of propagating media and raising its aeration. The percentages of rooting were significantly decreased linearly by decreasing compost: sand ratios (1: 2 or 1: 3). The usage of compost: sand at 1: 7 in both seasons and at 1:6 in the second season only resulted in significantly the highest rooting percentage. Statistically equal results were attributed to the contextually used medium (peat: sand at 1:3).  The similar trend occurred with the other root characteristics i.e. average root dry weight and number of roots / transplant.
