Abstract:
A field experiment was conducted during rabi seasons of 2021- 2022 at Mandsaur university, Mandsaur (M.P.) to identify the suitable cropping system and nitrogen level of chickpea and linseed under intercropping situation and their effect on productivity and profitability along with microbiological properties. The present experiment comprised of four cropping system and four nitrogen level replicated thrice in a two factor RBD by using F test. Results revealed that among the sole cropping significantly maximum growth attributes, growth analysis, number of nodules, nodules dry weight, yield attributes and yields, soil available nutrients (N 235, P 15.75 and K 338.75 kg ha^-1) and microbial population (rhizobium (9.2 x10⁷ CFU), azotobacter (12.1 x10⁷ CFU) and fungi (9.7 x10⁷ CFU)), except actinomycetes were recorded in both crop (Chickpea and Linseed) as against Chickpea + Linseed (1:1) and Chickpea + Linseed (1:2). Similar trends were also showed under nitrogen level where crops (Chickpea and Linseed) received nitrogen 60 kg ha^-1 being at par with nitrogen 40 kg ha^-1 did produce significantly maximum growth, yields, profit and soil available nutrients (N 252.50, P 15.75 and K 350 kg ha^-1) alongwith microbial population viz., rhizobium (9.6 x10⁷ CFU), azotobacter (13.9 x10⁷ CFU) and fungi (9.5 x10⁷ CFU) and minimum actinomycetes (5.6 x10⁷ CFU), whereas crop received no nitrogen did inferior. As its legume in nature and intercrops with oil seed crop, so it is highly eco-friendly and useful for sustainable agriculture besides maintain health of soil.
