Study of Urea Embed Mesoporous Nano Silica on Yield and Yield Attributing Characters of Rice Grown in Mollisols

Abstract

Rice (Oryza sativa L.) is a stable food more than two billion people are getting 60-70 per cent their energy requirement from rice and its derived products. Present research investigated effect of urea embed mNS (embed in the mesoporousnano silica by simple immersion loading using aqueous solution and this formulation of nanofertilizer) on rice crop in pot experiment under polyhouse condition. Nine treatments consisted (T1: Control, T2:N30P60K40,T3:N60P60K40, T4:N90P60K40, T5:N120P60K40, T6:N30(mNS)P60K40,T7:N60(mNS)P60K40, T8:N90(mNS)P60K40 and T9:N120 (mNS)P60K40.) in three replications. In this study, the results revealed that the growth parameter, grain and straw yields as well as yield attributes (effective tillers, panicle length, grains per panicle and 1000-grain weight) were significantly affected by urea embed nano silica application. The highest grain and straw yields were recorded in treatment T9 giving 323.02 and 124.05 per cent more over control, due to exposure of urea embed mNS as compared to ordinary urea dose of chemical fertilizers. The sustained release of urea embedded mNSaccurs 7-8 days after exposure which is extraordinarily slow as compared to ordinary urea. These results are preliminary but promising and open the doors to use nanomaterials as an efficient nanofertilizer.
