(Brassica junces var. toria) systems under ·bariland condition in
1996 summer seasoh·. The experiment was conducted in factorial
randomized complete design in three replicates with three levels of
N and four types of inter cropping of green manuring (GM). The
objective of the experiment was to find out the best combination of
different green manuring crops with different N level, to compare
residual · effec~s of different inter cropped.· g;reen manuring to
succeeding rape· .seed grain yield and to find out the most beneficial
combination of inorganic N with green manuring._ Soil organic matter
percentage and N percentage after harvest 9f rape seed were found
nonsignificnat. Organic matter and N were depleted after harvest of
rape seed as compared with them before planting of maize. Higher the
N dose more the depletion of N and faster the decomposition of GM
heavier the loss ,of nutrient from GM. Only for the treatment of Nat
60 kg/ha + cowpea had zero balance of N as -residual N. Soil pH
after harvest o.f rape seed was decreased·. than that of before
planting of maize. All the agronomical and yield components of maize
were found nonsignificant due to nitrogen level and inter cropping
of green manuring. Yield components and agronomical components of
. maize were not related with grain yield. Dry matter percentage and
dry matter yield of green manuring crops:,- · grain yield of maize due
to green manuring were highly significant. Residual effect of
