EFFECT OF WATER SOLUBLE FERTILIZERS ON GROWTH AND YIELD OF DRIP IRRIGATED AEROBIC RICE
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 15
Abstract
Experiment was laid out to know the effect of water soluble fertilizers on drip irrigated aerobic rice at Zonal Agricultural Research Station, Bengaluru during Kharif 2012. Drip fertigation at 1.5 PE up to maturity with 100 % RDF through WSF registered significantly higher plant height (53.6 cm), leaf area (3529 cm2), total dry matter (118.4 g hill-1), productive tillers (27.77 hill-1), panicle weight (4.23 g) total grains panicle-1 (170.80) which resulted in higher grain yield (6598 kg ha-1) and accounted 90.3 % increase in grain yield over surface irrigation with 100 % RDF. The same treatment also recorded higher water productivity of 78.2 kg-ha cm-1 by using only 844.4 mm of water. Hence, it is concluded that drip fertigation at 1.5 PE up to maturity with 100 % RDF through WSF found optimum for higher yield with reduced water use over surface irrigation.
