Effect of Liquid Organic Manures on Growth Attributes and Nutrient Uptake of Rice (Oryza sativa).

Field experiments were conducted at Annamalai University, Annamalainagar to study the effect of liquid organic manures on growth attributes and nutrient uptake of rice during Rabi 2011 (January to April) and Kharif 2011 (June to September). The experiments were laidout inrandomized block design with three replications. There were eleven treatments involving panchakavya, fish amino acid and vermiwash sprayed at different concentration and times. The results revealed that foliar application of vermiwash @ 5% at tillering and flowering stages significantly increased the growth parameters (plant height, number of tillers hill, dry matter production) are recorded higher nutrient uptake (nitrogen, phosphorus, potassium). This was followed by fish amino acid @ 3% at tillering and flowering stages.
