Abstract

Four rates of organic fertilizer (0 15 30 45 t/ha) were evaluated on three leaf-mustard cultivars organically grown under shelter. Yield responses to increasing rates of organic fertilizer for all the three cultivars showed a quadratic trend. The first cultivar (V1) is represented by the equation Y “0.0088x2 0.6887x 1.241 where Y yield in t/ha and x organic fertilizer in t/ha. The optimum rate of organic fertilizer (processed poultry manure) was 39.1 t/ha. Yield obtained at this rate was 14.7 t/ha. For cultivar 2 the yield response is represented by the equation Y “0.0028x2 0.2859x 0.699. The optimum rate of organic fertilizer was 51.1 t/ha. The yield at this rate was 8.0 t/ha. For cultivar 3 a quadratic relationship represented by the equation Y “0.0112x2 0.7517x 0.971 was obtained. The optimum rate of organic fertilizer was 33.6 t/ha and the yield at this rate was 13.6 t/ha. Fertilizer rates had a significant effect on P K Mn B Cu and Zn. A second crop grown on plots with residual fertilizers only gave yields ranging from 60 to 76 of yields from plots with fertilizer added.
