Abstract
The study was conducted to evaluate the performance of glutinous rice during wet season of 2018 was affected by nano-structured Silicon Dioxide foliar fertilizer. It was tested using Randomized Complete Block Design with three replications. The treatments were T1 Control (no Fertilizer), T2 90-40-60 kg N-P2O5-K2O/ha, T3 90-40-60 kg N-P2O5-K2O/ha + 1X NSS (20 DAT), T4 90-40-60 kg N-P2O5-K2O/ha + 2X NSS (20 and 40DAT), T5 90-40-60 kg N-P2O5-K2O/ha + 3X NSS (20, 40 and 60DAT). Blanket application of 1,000 ppm paclobutrazol wa sone at tillering starge, prior to stem. elongation.
Application of recommended rate of inorganic fertilizer significantly improved the plant height, number of tillers and dry matter yield of glutinous rice over the untreated plants while percent filled grains per panicle, weight of 1000 grains, grains per panicle and yield was unaffected.
Combining nano-structured silicon dioxide foliar fertilizer with the recommended rate of inorganic did not improve all the parameters tested. Moreover, spraying frequency of nano-structured silicon dioxide foliar fertilizer did not improve all the parameters. Spraying of nano-structured silicon dioxide foliar fertilizer to glutinous rice is currently not needed as soil silicon may still be sufficient.
