Influence of rice straw extract and amino acids on the growth, yield and chemical parameters of some crops [electronic resources]

There is increasing concern about environmental contamination risks associated with the extensive use of mineral fertilizer in crops production. The aim of this study is to evaluate rice straw extract as natural fertilizer and suitable alternative to nitrogen mineral fertilizer. Two successive field experiments were carried out at Giza, Agricultural Research Station, during two seasons of summer and winter /2015/2016 to study the effect of rice straw extract as soil addition and soaking seed with or without amino acids on yield of maize and wheat crops. Maize and wheat seeds were soaked in aqueous solution of rice straw extract without or with amino acids for 6, 12, 24 hours. The results indicated that there are significant differences between average of grain and biological yield of maize (15.59 and 23.56 t/ha), protein yield (1934.37 kg/ha) and N, P uptake (322.97, 129.4 kg/ha) by application of rice straw extract and seed soaking for 12 hours in rice straw extract mixed with amino acids as natural fertilizer compared to nitrogen fertilizer. Contrary, maize is better adapted and produce more yield than wheat, the data regarding grain and straw yield of wheat (8.97 and 22.1 t/ha) and protein yield (1256.91 kg/ha) and N uptake (228.45 kg/ha) was observed by application of rice straw extract and seed soaking for 6 hours with rice straw extract only compared to nitrogen fertilizer. It can be concluded that rice straw extract as natural fertilizer with or without amino acids could be suitable alternative to nitrogen mineral fertilizers.
