Effect of foliar feeding of liquid organic manures on yield and economics of rice

摘要

Field experiments were conducted at Annamalai University, Annamalainagar to study the effect of foliar feeding of liquid organic manures on yield and economics of rice during Rabi 2012 (January to April) and kharif 2012 (June to September). The experiments were laid out in randomized block design with three replications. There were eleven treatments involving panchakavya, fish amino acid and vermiwash sprayed at different concentrations and time. The results revealed that foliar application of vermiwash @ 5 % at tillering and flowering stages resulted in significantly higher number of grain and straw yield, followed by fish amino acid @ 3 % at tillering and flowering. Foliar application of vermiwash @5% at tillering and flowering recorded significantly higher net return and B : C ratio.
