A field experiment was conducted to assess the effect of integrated nutrient management
system on kharif forage sorghum (cv. Phule Amruta)-chick pea (cv. Digvijay) cropping
sequence on vertisol during 2006-2007. The results indicated that significantly higher
values were observed for growth and yield attributes with highest grain and straw yield
(22.4 qha-1 and 24.2 qha-1) of succeeding chick pea cv. Digvijay in rabi season, due to the
residual effect of application of 25 % N through FYM + 25 % N through vermicompost + 50
% N through RDF applied to preceding forage sorghum in kharif season followed by 100 %
RDF (21.2 qha-1 and 23.6 qha-1) application, respectively. Significantly lowest grain yield
(13.3 qha-1) and straw yield (16.0 qha-1) was recorded by absolute control. Residual effect of
25 % N through FYM + 25 % N through vermicompost + 50 % N through RDF applied to
forage sorghum also recorded significantly highest value for nutrient uptake, gross returns
(Rs. 51655/ha), net returns (Rs. 32364/ha) and maximum value for benefit : cost ratio (2.60)
of succeeding chickpea compared to the application of reduced or higher value of RDF in
combination with the organic manures or alone inorganic fertilizer to preceding
