Effect of Silicon Fertilization on Physiological Parameters and Yield of Hybrid Maize under Irrigated and Rainfed Conditions

Abstract

A field experiment was conducted to study the effect of silicon fertilization on physiological parameter and yield of hybrid maize under irrigated and rainfed conditions during Rabi, 2017-18 at eastern block farm of Tamil Nadu Agricultural University, Coimbatore. The treatments comprised of two factorsviz., three irrigation strategies and two silicon sources as seed priming and foliar application. The results of the study indicated that adequate irrigation strategy registered significantly higher physiological parameters, grain yield (6679 kg/ha) and stoveryield. Silicon application as seed priming with 1.5 mM of sodium meta silicate and foliar application of silicic acid @ 0.2 % at knee high and tassel initiation stages was recordedhigher physiological parameter like SPAD meter value and Relative Water Content (RWC) and grain (6130 kg/ha) and stoveryield.It was comparable with foliar application of silicic acid @ 0.2 % at knee high and tassel initiation stages alone in registering higher growth and yield of maize.
