Abstract

Field experiments were conducted at Annamalai University, Annamalai Nagar to study the influence of vermiwash on the growth, yield attributes and nutrient uptake of rice during Navarai 2013 (January to April) and Kuruvai 2013 (June to September). The experiment was laid out in randomized block design with three replications. These were eleven treatments involving panchakavya, fish amino acid and vermiwash sprayed at different concentrations and time. The results of the study revealed that foliar application of vermiwash @ 5% at tillering and flowering stages had resulted in significantly better plant growth in terms of plant height, number of tillers and dry matter production, higher number of yield attributes,grain and straw yield. This was followed by fish amino acid @ 3% at tillering and flowering.Foliar application of vermiwash @ 5% at tillering and flowering resulted in significantly increased nutrient uptake in rice.
