Around metal elements, Cu and Zn would micro nutrients as they are essential in trace concentrations for physiological processes in plants. Furthermore consequently would a critical part from the soil–plant–food continuum. Therefore this study aimed to analyzing the performance of multivariate hyperspectral vegetation indices of wheat (Triticum aestivum L.) in estimating the accumulation of these elements in plant dry mutter and the final product of Egyptian wheat crop irrigated with high concentrations of Zn and Cu. We applied five concentrations for each element (0.05, 20, 40, 100, and 150 ppm of Zn) and (0.02, 8, 10, 12, and 15 ppm of Cu) to a controlled greenhouse experiment to examine the effect of these concentrations on plant spectral characteristics and study the possibility of using spectroradiometry measurements for identifying the grain content of these metals. The results demonstrated that The hyperspectral vegetation indices had a potential for monitoring Zn concentration in the plant dry matter. NPCI and PSSR had a highest correlation with Cu phytoaccumulation into the grains with highest significant level (P-Value < 0.01) and (r) values (-0.39, -0.42). Conclusively, Results of present study demonstrate that hyperspectral reflectance data, as well as studied VIs appears to have potentials for monitoring the phytoaccumulation of Zn into above-ground parts of wheat. The hyperspectral vegetation indices had insignificant correlation with Zn accumulation in to the grains, but it had a significant negative relationship with Cu concentration in grains with low correlation coefficient values.   }, keywords = {Heavy metals,Remote Sensing,Vegetation Indices,detecting stress}, url = {https://jpd.journals.ekb.eg/article_41905.html}, eprint = {https://jpd.journals.ekb.eg/article_41905_5cc6e763921d52738d2a9efd639aedfb.pdf} } @article { author = {Gouda, Noura and El-Kelawy, Hassan and El-Gafaary, Mohamed and Ibrahim, Hassan}, title = {UTILIZATION OF Moringa oleifera AS A NEW RABBITS FEED. 2- EFFECT OF DIETARY INCLUSION OF Moringa oleifera HAY ON REPRODUCTIVE AND PRODUCTIVE PERFORMANCE OF DOE RABBITS}, journal = {Journal of Productivity and Development}, volume = {22}, number = {3}, pages = {429-446}, year = {2017}, publisher = {Zagazig University.

The differences in chemical composition of meat between the growing NZW rabbits either fed different level of Moringa oleifera hay (leaves +twigs) as a substitute for alfalfa hay in the diet or control animals were insignificant.Conclusively, the results of the present study demonstrated that, Moringa oleifera hay (leaves+ twigs) is supportive as unconventional source of protein for feeding growing rabbits and could be added in the diet at levels up to 15% to replace about 75% of alfalfa hay without any adverse effects on productive traits of growing NZW rabbits. }, keywords = {Moringa oleifera,feeding,productive performance,Growth performance,rabbits INTRODUCTION}, url = {https://jpd.journals.ekb.eg/article_42113.html}, eprint = {https://jpd.journals.ekb.eg/article_42113_2b24ec11bc1a8bdccf28c6bf5d9a4919.pdf} } @article { author = {Mohammed, Ahmed}, title = {AN ECONOMIC STUDY FOR SOME FARMING PRACTICES AFFECTING SUGAR BEET PRODUCTIVITY IN BEHIERA GOVERNORATE}, journal = {Journal of Productivity and Development}, volume = {22}, number = {3}, pages = {657-682}, year = {2017}, publisher = {Zagazig University.

The results indicated that there significant positive impact for the method of leveling the soil for plantations, plantation date, number of irrigations, number of fertilizer additions and the quantity of fertilizer on sugar beet productivity. Sugar beet productivity reached 12.36 ton per feddan with normal soil leveling and late plantation and less than 8 irrigations, and once fertilizer addition, and fertilizer quantity less than 50 units, compared by soil leveling by laser, and planting in medium season, and irrigations number more than 10 irrigations and fertilizer addition to twice, and fertilizer quantity between 50-75 unites, give high productivity equals 22.31 ton per feddan.  }, keywords = {Farming practices,economic and production}, url = {https://jpd.journals.ekb.eg/article_42114.html}, eprint = {https://jpd.journals.ekb.eg/article_42114_6421d62cf888b2fdb86aeb51f6e3867b.pdf} } @article { author = {Hussein, Esraa}, title = {BEHVIOUR OF PRIME SEEDLESS GRAPEVINES GROWN UNDER SANDY SOIL CONDITIONS TO FOLIAR APPLICATION OF CHITOSAN}, journal = {Journal of Productivity and Development}, volume = {22}, number = {3}, pages = {683-696}, year = {2017}, publisher = {Zagazig University.

Algae extracts (Bluegreen), and potassium dissolving bacteria i.e., Baccillus circulans (potssioumag) were used as biofertilizer sources for N and K, respectively beside mineral NK levels.Results showed that the superiority values of plant survival, plant height and number of leaves were detected with decreasing the recomended NK mineral dose to 75% plus biofertilizers twice / season. The same combination treatment significantly produced the highest early and total yield, moreover, the mixture of full mineral dose (100%) and biofertilizers significantly proved superiority in total yield compared with the control. In addition, biofertilizers plus 75% or 100% mineral NK reflected improvements in all measured parameters of flower head, i.e., weight, length and diameter as well as receptacle, i.e., weight, length and thickness as compared to the mineral fertilizing alone. Whereas, the highest values in all of these parameters were recorded may be due to the combination between 75% NK mineral dose and biofertilizers twice a season. In addition, the highest quality expressed as the highest values of inulin, total carbohydrates and lowest value of fiber percentage was recorded by using 75% mineral NK and biofertilizers twice / season. Concerning NK receptacle content, the highest values were recorded as a result of fertilizing the plants by 75% mineral NK plus biofertilizers twice / season.Conclusively, this study suggests that using biofertilizers twice / season could be useful for saving 25% of the recommended mineralNK with improving in survival plants, vegetative growth parameters, early and total yield as well as its quality.}, keywords = {Globe artichoke,nitrogen,potassium,Baccillus circulans,cyanobacteria (bluegreen algae)}, url = {https://jpd.journals.ekb.eg/article_42117.html}, eprint = {https://jpd.journals.ekb.eg/article_42117_9937ec77b89212c57d31ab306df69903.pdf} } @article { author = {Fekry, Wafaa and El-Shatoury, Rowaa}, title = {EVALUATE PLANT GROWTH, GREEN POD YIELD AND ITS QUALITY OF THE TWO PEA CULTIVARS ENTSAR 1 AND MASTER B WITH DIFFERENT PLANT DENSITIES}, journal = {Journal of Productivity and Development}, volume = {22}, number = {3}, pages = {715-728}, year = {2017}, publisher = {Zagazig University.
