Effect of nitrogen on rice yield, yield components and quality parameters

Abstract

99 g). Among the different N application levels, significant difference was observed in all quality parameters except gelatinization temperature (GT); the highest amylose content (AC) was obtained from treatment N1 and significantly highest gel consistency (GC) was obtained from treatment N3. In general, GC was increased with N-fertilizer application and only result was changed from N3 to N4 and was reduced. Whereas AC was reduced from N1 to N3, and the result was reversed from N3 to N4. Meanwhile, the interaction effect of variety × nitrogen fertilizer did not show significant difference between all quality parameters except of GC.

Effects of nitrogen and tiller type on grain yield and physiological responses in rice

“…Previous studies have reached different conclusions on yield-related parameters (number of spikelets per panicle, grain filling percentage, and grain weight), which either increased ( Jian et al 2014 ), were not affected ( Mandana et al 2014 ), or even decreased ( Li et al 2014 ), following the application of N fertilizer. These phenomena might be explained by our experimental results.…”

The Use of Fly Ash in Peat Soil on the Growth and Yield of Rice

“…YosefTabar (2013) reported that the application of N and P fertilizer increased the number of grain, weight of 1000 grain and yield of rice. Another studies noted that application N fertilizer increased panicle per hill, total grains per panicle (Haque & Haque, 2016), weight of 1000 grains and yield of the grain (Haque & Haque, 2016;Mandana, Akif, Ebrahim, & Azin, 2014;YosefTabar, 2013). Arivazhagan et al (2011) reported that the application of fly ash at 50 tha-1 increased the yield of cereal crops from 5-20%, vegetable crop from 5-20%, plantation crops from 20-30%, rice crop 13-17%, sugarcane crop from 15-30%, maize crop from 36-40% and potato crop from 25-37% over control.…”

Influence of integrated in-soil zinc application and organic fertilization on yield, nitrogen uptake and nitrogen use efficiency of rice

“…The crop occupies onethird of the world's total area planted to cereals and provides 35 to 60% of the calories consumed by 2.7 billion people. (Mandana et al, 2014). The production of an economic crop of rice without high rates of mineral fertilizers suitable for new varieties of rice distinguished in the high yield in the soil is poor content of organic matter is one of the most important challenges faced by researchers, especially in Egypt.…”
