Residual effect of weed management and phosphorus applied to Indian mustard (Brassica juncea) on succeeding fodder maize (Zea mays)

Abstract

An investigation was carried out during 1998 99 and 1999 2000 at Udaipur, to study the residual effect of weed management and phosphorus treatments applied to previous crop of Indian mustard [Brassica juncea (L.) Czernj. Coss on] on fodder maize (Zea mays L.) and weeds in summer season. Fodder yield of maize was significantly increased during 1999 2000 owing to residual effect of different weed management treatments. Similarly, residual effect of phosphorus fertilization significantly increased the value of growth parameters and fodder yield of maize as well as weed dry matter during both the years. The mean increase was 8.30% in fodder yield owing to residual response of phosphorus at 40 kg P,O ha over the control.
