Abstract

Field experiment was conducted during 2003-04 to study the effect of vermicompost, farmyard manure and water hyacinth compost in comparison to chemically fertilized and unfertilized plots on crop-plants in HYV Swarna and local variety Magaisal. The experiment followed split plot design with two varieties of rice in the main plots and five nutrient sources randomized in sub plots. Signifi cant variation in grain yield between the varieties, among the nutrient sources and their interactions was observed. Grain yield recorded in HYV Swarna was higher to local variety Mugaisal irrespective of the treatments and hence Swarna was considered to be more tolerant to Mugaisal. Among the nutrient sources, treatment with vermicompost imparted maximum grain yield to all other nutrient sources irrespective of varieties.
