Abstract

A Field experiment was conducted at Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during rabi season of 2019 to study about the changes in the physiological parameters of aerobic rice under different drip fertigation and irrigation levels. Thirteen treatments consists of 75% and 100 % pan evaporation ( two irrigation levels) and 75%, 100% and 125% RDF (three fertigation levels), combination with fermented fish waste (FFW) and fermented egg product (FEP), surface irrigation treatment as a check were arranged in randomized block design and replicated thrice. The result showed that significantly higher leaf area index, SPAD values, crop growth rate, relative growth rate and yield during rabi season 2019 were observed in drip fertigation at 125% RDF, 100% PE with FFW (3 times) than all other treatments. Which was closely related with drip fertigation at 125% RDF, 100% PE with FEP (3 times). The lower grain yield and physiological parameters were noticed in drip fertigation at 75% RDF, 75% PE with FEP (3 times). This study concluded that drip fertigation at 125% RDF, 100% PE with FFW (3 times) suitable for getting higher physiological parameters and grain yield in aerobic rice.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
