Response of Egyptian Hybrid Rice One Cultivar to Times of Nitrogen Application and Foliar Spraying of Ascobien Compound

Abstract

Two field experiments were conducted at the Experimental Farm of Rice Research and Training Center (RRTC),Sakha, Kafr el-sheikh, Egypt during 2014 and 2015 seasons. The objective of this investigation was aimed to study the response of Egyptian hybrid rice one cultivar (SK 2034 H) to times of nitrogen fertilization and foliar spraying of ascobien compound. The nitrogen times of fertilization included four treatments i.e. Basal soil (B), Mid tillering (MT), panicle initiation (PI) and booting stage (BT). Foliar application of ascorbien compound at rate of 1.050 Kg/fed at two dates as follows, without ascorbien, spraying after transplanting by 25 days and at 25 and 45 days from transplanting. The main finding could be summarized as follows,1-Nitrogen fertilization splitting at rate of (69 Kg N/fed) at 17.25 Kg N/fed at B+ MT+ PI+ BT significantly maximize leaf area index, number of tillers /hill, number of filled grain/hill, 1000 grain weight and grain yield/fed, hulling, milling and broken rice percentage. 2-Foliar spraying of ascorbien compound twice at 25 and 45 days from transplanting significantly increased the previous studied traits as we mentioned before. 3-The interaction between times of nitrogen fertilization and foliar spraying of ascorbien compound significantly affected all the studied characters in this study. It could be concluded that splitting nitrogen at four equal doses (17.25 Kg N/fed) and foliar spraying of ascorbien compound at 25 and 45 days from transplanting of Egyptian hybrid rice one cultivar (SK 2034 H) was the recommended treatment to improve growth, yield components and grain quality and produced the greatest grain yield (4.48 t/fed) under the environment condition of Sakha Kafr El-sheikh.

Evaluation of New Egyptian Japonica Green Super Rice Varieties Under Fertilization and Plant Spacing

“…Rice grain and straw yields were improved by using the ideal levels of chemical NPK fertilizers (El-Kramany et al, 2010;Elekhtyar, et al, 2016). N0P0K0 had the lowest value (Elekhtyar 2016;Wissa et al, 2016). On the other hand, no treatment had a positive effect on the interaction in the two seasons.…”

Effect of Foliar Application of Phosphorus, Zinc, and Silicon Nanoparticles along with Mineral NPK Fertilization on Yield and Chemical Compositions of Rice (Oryza sativa L.)

“…Silicon increased nitrogen and phosphate levels in rice grains and straw [58] and increased the N uptake by roots, shoots, and grains when compared to the NK + Si treatment These increased nitrogen uptakes may be attributed to lead erectness, which facilitated better penetration of sunlight, resulting in a higher photosynthetic activity of the plant and higher carbohydrate production. Silicate foliar treatments had a significant impact on nitrogen concentration and uptake value [59][60][61]. Nano Zn and Si increased P uptake, and silicon application increased phosphate uptake in rice, which directly correlates with increased growth and yield [58].…”

Effect of Plant Growth-Promoting Rhizobacteria and Cyanobacteria on Physico-chemical and cooking characteristics of Giza 179 rice grains

“…They can also reduce the levels of ethylene concentration by converting auxin into indole acetic acid (IAA), gibberellic acid (GA), cytokinins, and ABA in rice roots. They may Improve capacity to generate antagonistic antibacterial agents, ß1-3-glucanase; and improved drought and other stress tolerance by generating water-soluble vitamins niacin, thiamine, riboflavin, biotin, and pantothenic acid are some of the benefits (Kaushal et al, 2013;Wissa et al, 2016). As a result, create a healthy rice grain with great milling properties.…”
