The experiment was laid out in a split-plot design with four replications. The organic fertilizer was allocated in the main plots while the sub-plots received potassium treatments. The studied characters were plant height, number of tillers, number of panicle hill-1, panicle weight, panicle length, number of branches panicle-1, number of filled grains panicle-1 and number of unfilled grains panicle-1, 1000-grain weight, grain and straw yield and some grains quality characters i.e. hulling, milling and head rice percentage as well as available and uptake of potassium .The main results revealed that application of both compost rice straw (CRS) and rice straw (RS) gave the same greatest values of all the previous characters except panicle length which gave insignificant effect. Application of potassium fertilizer at the rate of 60 kg K2O ha-1basally applied before planting (K1) or as foliar spray at the rate of 2% K2O at both panicle initiation (PI) and late booting (LB) produced the highest values of all the studied characters.

Hulling% reached the maximum value when treated with 5 t CRS ha-1 while both milling and head rice responded to 5 t RS ha-1. Treatment of potassium applied as a foliar spray at both PI and LB (K3) produced the highest hulling and milling% while head rice% responded to K2 and K3. The combination of 5 t RS ha-1 with K1 or K3 gave the highest hulling and milling% while head rice reached the maximum value when each of CRS and RS was combined with each of K1, K2 and K3. Available K reached the maximum value at 30 days after transplanting. Availability of K was the highest under rice straw treatment followed by CRS. The uptake of K reached to the greatest value when either CRS or RS was combined with K1 treatment. It can be concluded that combination of 5 t CRS ha-1 with K3 (2% K2SO4 as a foliar spray at both PI and LB) produced the greatest grain yield and saved about 40 kg K2O ha-1. Also, the combination of either 5 t CRS or 5 t RS ha-1 with K3 treatment improved the grain quality under study.   }, keywords = {}, url = {https://jpp.journals.ekb.eg/article_36244.html}, eprint = {https://jpp.journals.ekb.eg/article_36244_59cb79b48f4e5f34cf44e77245b55c85.pdf} } @article { author = {Shaddad, A. and Ghieth, W. and Hegazy, A.}, title = {Effect of Sulfur and Potassium Application under Salinity Stress on Productivity and Fruit Quality of Swelling Peach Cultivar}, journal = {Journal of Plant Production}, volume = {10}, number = {2}, pages = {153-163}, year = {2019}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2019.36245}, abstract = {This study was conducted during two successive seasons (2016 and 2017) at El-Sheikh Zwayed, North Sinai Governorate, Egypt.

Water shortage stress significantly reduced vegetative growth (main stem length, branches number, foliage fresh weight, leaves number and leaves area per plant and yield components; fruits weight and numbers per plant, Vit. C, TSS and total yield (ton/fed.). On contrary, foliar application of SA significantly improved these parameters under water shortage stress conditions. However, the lowest used water irrigation quantity increased leaf and fruits dry matter percentage, sex ratio and water use efficiency. On the other hand, water shortage stress significantly reduced leaf pigments (chlorophyll a, b and carotenoid) as compared to the highest rate (1200 m3) and these were further increased by using SA. Salicylic acid at a concentration of 0.30 g/l gave the highest fruits yield and its components.

Application of Tolclofos-methyl fungicide at high rate caused marked decline in leaf chloroplast pigments, and carotenoids were more influenced. Total water content and leaf water deficit increased but the relative water content decreased as a result of Tolclofos-methyl application. Transpiration rate tended to increase at the lower dose of Tolclofos-methyl but decrease at its higher rate. Membrane integrity was increased with increasing the fungicide rate. Mineral elements (N, P, K, Ca, Mg, Fe, Zn, Mn), plant growth promoter substances (IAA, GA3, Cytokinins), and total free amino acids were reduced, whereas ABA, proline content, total phenol and the activity of phenoloxidase and peroxidase were increased in the fungicide exposed plants. Using Tolclofos-methyl fungicide at the high rate significantly reduced the number of flowers and fruit, vitamin C content of the fruits, yield, and water use efficiency of tomato plants. Total soluble solids and acidity in tomato fruits were increased, whereas lycopene content was decreased. Tolclofos-methyl fungicide residue in tomato fruits was dramatically enhanced above the maximum level of residue of Tolclofos-methyl fungicide (100 µg kg-1 in tomato fruits) and reached 176.8 and 423.2 µg kg-1 fresh weight at the rates of 2 and 4 g m-2 soil, respectively. Application of Bacillus, Trichoderma, GA3 and BP caused marked enhancements in the growth, yield, plant water relations, biochemical constituents, photosynthetic pigments and chemical properties of tomato fruits under both of the normal and fungicide pollution conditions. In addition, using these agents reduced the fungicide residue in fruits by about 42, 73, 35 and 5 % at the fungicide rate of 2 g m-2 soil and by about 80, 38, 68 and 47% at the rate of 4 g m-2 soil, respectively. It could be concluded that Trichoderma followed by Bacillus at the recommended dose of fungicide or Bacillus followed by GA3 at the exceeded dose of fungicide are useful tools to alleviate the phytotoxic effects and reduce the residue level of Tolclofos-methyl in tomato fruits below its maximum level.}, keywords = {Tomato,Tolclofos-methyl,Agents,physiological aspects,Biochemical Constituents,yield,Fungicide residue}, url = {https://jpp.journals.ekb.eg/article_36247.html}, eprint = {https://jpp.journals.ekb.eg/article_36247_2d0faafae4820b24d27fc4575ab043be.pdf} } @article { author = {Selim, Abdel-Fattah and Selim, Dalia}, title = {Physio-Biochemical Behaviour, Water Use Efficiency and Productivity of Wheat Plants Exposed to Magnetic Field}, journal = {Journal of Plant Production}, volume = {10}, number = {2}, pages = {185-191}, year = {2019}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2019.36248}, abstract = {The aim of this study was to evaluate the capability of magnetized field in improving the growth, physiological and biochemical aspects and yield attributes of wheat crop (Triticum aestivum L. cv Giza 168) as one of the important economically strategic crops.

Magnetic treatments were magnetic grains, magnetic water and combined magnetic grains and water in addition to the control group. Vegetative growth of wheat plants was significantly increased by treating with different magnetic treatments compared to the control plants. Application of magnetic treatments caused significant increases in total leaf water content, relative water content, water use efficiency (WUE), membrane permeability and succulence degree, whereas the transpiration rate and leaf water deficit were significantly reduced. Most growth characteristics and WUE were more positively affected by the magnetized water treatment than other magnetic treatments. The concentrations of photosynthetic pigments and growth promoters (IAA, GA and Cytokinins) showed significant increases in the treated wheat plants with all magnetic treatments. A marked increase was observed in the uptake of N, P, K, Ca, Mg, Fe, Cu and Mn, but Na uptake was decreased in wheat plants by the application of magnetic field.

Field and storage experiments were conducted at El-Baramoun farm and Mansoura Horticulture Research Station, Dakahlia governorate, Egypt to study the agronomical performance response of cowpea cv. Kafr El -Sheikh-1 grown under high temperature and long photoperiod conditions of late summer seasons of 2017 and 2018 to some natural and safe treatments i.e., neem oil (2.5ml/L), chitosan (CS) at 200ppm, chitosan nanoparticles (CSNPs) at 100 ppm and potassium silicate (K-silicate) at 300ppm and their interactions compared with the recommended synthetic insecticide (lannate) at 75g/100L and unprotected control (tap water). The response of infestation of the pod borer (Etiella  zinckenlla), as  one of the determinants for yield and quality of green pods in the field and dry seeds in the store, to the assigned individual treatments and a treatment of magnetized sea water + iron (Fe) salts were also concluded. In this work, the subsequent storability and insect damage of dry seeds at the ambient temperature for 5 months were studied in terms of either the effect of prior treatments during the field experiment or the effect of post-harvest treatments i.e., natural essential oils of neem, camphor and thyme at 2.5ml/kg seed in comparison with unprotected control and synthetic insecticide (Celphos 57%) at 50mg/kg seeds.The most important results could be summarized as follows:The physiochemical characterization of chitosan nanoparticles cleared that the nanoparticles have, smooth surface, spherical shape and size about 32 nm.All protected treatments considerably differed in improving the agronomical performance over unprotected control at the two seasons. Both mixed treatments were more effective in this regard, since the treatments of neem oil+ K-silicate combined with either CSNPs or CS were superior in increasing vegetative traits, relative water and total chlorophyll contents, green pod yield (47.5% and 46.6%) and dry seed yield (82.8% and 73% ), respectively over unprotected control. The magnetized sea water + Fe salts recorded the highest reduction in pod borer infestation (82.16%), followed by CSNPs (81.16%) compared with the insecticide (76.14%).Concerning the seed storability as affected by prior treatments during field experiment, mixed treatments were more superior in protecting stored seed, especially neem oil+ K-silicate+ CSNPs treatment which  reduced seed damage% and infested seed% from 100% (control) to 7.15 and 6.32 % and to 12.11 and 11.14% in 1st and 2nd seasons, respectively. As for the effect of post-harvest treatments, Celphos 57% was the most effective treatment, since damage% and infested seeds % reduced to 0%, followed by neem and thyme oils (less than 10%).Eventually, foliar spray of neem oil+ K-silicate combined with either CSNPs or CS five times during the growing seasons may introduce integrated solutions for biotic and abiotic stresses during field and storage of cowpea. Also for the best stored seeds at the ambient temperature for 5 months, neem and thyme oils (2.5ml/kg seed) are the most recommended natural and safe applications.}, keywords = {Vigna unguiculata L.

Exposing plants to water deficit levels (75% and I 50% ETc) decreased in all growth characters studied, water relations (total water content, relative water content, osmotic pressure, transpiration rate and plasma membrane integrity), photosynthetic pigments, chemical composition (total carbohydrates, total soluble sugars, N and K) as well as yield and its components (number of spikes/ m2, number of grains /spike, spike weight, 1000-grain weight, grain yield /fed and straw yield /fed) in comparison with well-watered plants (Control, 100 ETc).

Application rate 10 ppm JA + 5% lithovit surpassed most of the other tested characters studied in both growing seasons. The interactions between water regimes and stress defense substances (JA and Li) were found to be significant for most studied traits. Wheat grown under normal irrigation integrated with application of 10 ppm JA + 5% lithovit generally produced the highest values of growth, photosynthetic pigments as well as yield and its components. Moreover, application of 10 or 20 ppm jasmonic acid + 5% lithovit under water stress conditions led to an increase in all vegetative growth characters, water relations (total water content, relative water content and osmotic pressure), photosynthetic pigments, chemical composition of the leaves (total carbohydrates and total soluble sugars contents, N and K percentages) as well as yield and its components, while caused a significant decrease in transpiration rate, plasma membrane integrity, proline, activities of peroxidase and phenoloxidase enzymes.

The selected trees of peach  (cv. Medium Sultani) were sprayed Pre-harvest (1.5 month after full bloom) with one   of the followings: tap water (control), 1.5% potassium sulphate (K2SO4), 2% calcium chloride (CaCl2) and the combination of them. The harvested mature fruits were cold stored at 5 ± 1°C and 80-85% relative humidity (RH) for a storage period of 24 days. Some physical and chemical quality characteristics were measured on the intact treated fruits at harvest date and at 6-day-intervals during cold storage up to 24 days. The obtained results showed that the peach fruits sprayed with 1.5% K2SO4 recorded the highest values of firmness, Vitamin C content and TSS% after 6, 12 and 18 days during The cold storage in both seasons.
