“…By contrast, Ning et al (2010) found a significant influence of N on amino acid composition of brown and milled rice, in particular Phe and Tyr. Similarly, Chang et al (2008) reported that N significantly increased the content of essential amino acids in rice grains. Of note is that the results above are mainly based on analysis of mature grains, little information is available concerning the time course accumulation of FAA and PAA during grain filling.…”

“…By contrast, Nam et al (2014) found concentrations of aspartic acid, phenylalanine and valine in rice grains were significantly elevated by drought treatment. Chang et al (2008) reported that N stress significantly reduced N accumulation in rice grains, leading to a decrease in protein content, total amino acids, and essential amino acids. The study of Ning et al (2010) on rice revealed that Lys content in rice grains showed an increasing trend as N fertilizer increased.…”

“…Phosphorus is the second most required plant nutrient for field crops. It plays a vital role in several physiological processes of plants (Mandal and Khan, 1972 ; Singh and Sale, 2000 ; Chang et al, 2007 ; Amanullah, 2011 ; Vahed et al, 2012 ). It is always inadequate under rice based system in Northwest Pakistan to meet the requirement of rice plants (Amanullah and Inamullah, 2016a , b ).…”

The objective of this research was to evaluate the impact of organic sources (animal manures vs. plant residues at the rate of 10 t ha−1 each) on the productivity of hybrid rice (Oryza sativa L.) production under different levels of phosphorus (0, 30, 60, and 90 kg P ha−1) fertilization. Two separate field experiments were conducted. In experiment (1), impact of three animal manures sources (cattle, sheep, and poultry manures) and P levels were studied along with one control plot (no animal manure and P applied) was investigated. In experiment (2), three plant residues sources (peach leaves, garlic residues, and wheat straw) and P levels were studied along with one control plot (no plant residues and P applied). Both the experiments were carried out on small land farmer field at District Swabi, Khyber Pakhtunkhwa Province (Northwest Pakistan) during summer 2015. The results revealed that in both experiments the control plot had significantly (p ≤ 0.05) less productivity than the average of all treated plots with organic sources and P level. The increase in P levels in both experiments (animal manure vs. plant residues) resulted in higher rice productivity (90 > 60 > 30 > 0 kg P ha−1). In the experiment under animal manures, application of poultry manure increased rice productivity as compared with sheep and cattle manures (poultry > sheep > cattle manures). In the experiment under plant residues, application of peach leaves or garlic residues had higher rice productivity than wheat straw (peach leaves = garlic residues > wheat straw). On average, rice grown under animal manures produced about 20% higher grain yield than rice grown under crop residues. We conclude from this study that application of 90 kg P ha−1 along with combined application of animal manures, especially poultry manure increases rice productivity. Also, the use of either garlic residues or peach leaves, never applied before as organic manures, can increase crop productivity and will help in degraded soil for sustainable soil management.

“…We also calculated the relative proportion of each carbon skeleton backbones to total amino acids, and, on the average irrespectively of fertilization practices, α-ketoglutarate, oxalate, 3-phosphoglycerate, phosphoenolpyruvate and pyruvate occupied 34.3, 23.5, 12.8, 9.3 and 20.1% (data not shown), respectively. The fertilization, especially N, and fertile soil not only improve the nutritional quality, such as amino acids and storage proteins, of cereal grain but also enhance essential amino acid, lysine, which is deficient rice grain (Chang et al, 2008;Kaul and Raghaviah, 1975). However, it is also recognized that higher nitrogen input often results in unfavorable taste and texture properties.…”

Our government has performed to support the nation-wide application of customized fertilizer based on soil-testing results and crop nutrient balance in order to promote the environment-friendly agriculture and to respond the global environment guide-line since 2010. This study was performed at the selected local paddy fields (Hwaseong-si, Uiseong-gun and Miryang-si) with different soil chemical properties in 2012. The contents of amino acids measured showed an increasing trend with fertilization, and glutamic acid was the most abundant amino acid followed by aspartic acid, leucine and alanine. However, valine, isoleusine, tyrosine and lysine were not significantly affected by fertilization. The significant differences in grain N, expressed as a crude protein, and amino acids dose was observed between experimental sites (p<0.001), treatments (p<0.01 to 0.001) and interaction of both factors (p<0.01 to 0.001). In our experiment the following order of carbon skeleton backbones to produce amino acids was observed irrespective of experiment sites and fertilization: α-ketoglutarate > oxalate > pyruvate > 3-phosphoglycerate > phosphoenolpyruvate. In conclusion, customized fertilizer had no difference in amino acids compared to the conventional-NPK practice which was higher than in no fertilization, and also the normal paddy represented slightly higher amino acids compared to the reclaimed. Further study based on the present results is required to investigate what is main factor to amino acids between genetic and environmental factors.
