Effect of different levels of N,P,K and vermicompost on growth and yield of Maize ( Zea mays L.)

Abstract

A field experiment was conducted on effect of different levels of N,P,K and vermicompost on growth and yield of maize (zea mays L) during kharif season 2012. The experiment was laid out in randomized block design with three replications , with 3x3 factorial RBD , consisted nine treatment it was so observed that the best findings were reported for maize growth and yield treatment T8, I2, V2 (N120, P60, K40, Kg ha-1 and vermicompost 8t ha-1), maximum plant height 132.47 (cm), maximum number of leaves 10.67, maximum stem diameter 2.18 (cm), maximum dry weight 1060( g) maximum length of cob 19.41 (cm), maximum test weight 227.05(g), maximum grain yield 55.90 (q ha -1) respectively, pant height , stem diamteter, length of cob, grain yield were found to be significant and number of leaves , dry weight, test weight were found to be non- significant , and treatment T6, I2,V0 (N120, P60, K40 Kg ha -1 and vermicompost 0 t ha -1) the maximum cost benefit ratio was recorded as 1:2:42 was at par than any other treatment combination , followed by in T3, I1, V0 (N60, P30, K20, Kg ha -1). Adequate plant nutrient supply holds the key for improving the food grain production and sustaining soil fertility.
