Abstract
An experiment was conducted on Vertisol of Navasari during 1989--90 and 1990-91 to study the effect of weed-control practices and nitrogen in Indian mustrard [Brassica juncea (L.) Czernj. & Cosson] and their residual effect on succeeding greengram (Phareolus radiatus L.). Ten weed-management treatments were laid out in split-plot design with 3 replications. The greengram cmp was superimposed in summer with 2 levels of nitrogen in split-split-plot design. Though higher yield was obtained with weed-free condition, comparable yield was recorded with 2 hand-weedings, pendimethalin alone or supplemented with hand- weeding owing to effective weed control. Higher yield was also obtained with 90 kg Nlha but remained at par with 75 kg Nha, indicating better utilization of applied N. Higher uptake of nutrients (NPK) was recorded with weed-free condition and graded doses of N. Like- wise, higher oil yield was obtained with these treatments. The weed-minagement practices as well as nitro- gen application followed in preceding Indian mustard crop did not leave any residue to affect the yield of succeeding crop of greengram adversely or favourably. However, the seed yield of greengram was signifi- cantly increased with 20 kg Nlha.
