Title : Performance of chickpea under pigeonpea based sequential intercropping systems and integrated nutrient management in black soils of Telangana state, India

Abstract :

An experiment was carried out during kharif and rabi seasons of 2019-20 and 2020-21 at ARI, Rajendranagar, Hyderabad. The experiment was laid out in randomized block design (Factorial) with two factors i.e., one with six levels of sequential intercropping systems of pigeonpea (S1 to S6) and other with two levels of nutrient management practices (N1 – Recommended dose of fertilizers and N2 - an integrated approach). A separate sole cropped treatment of chickpea (S) was sown under both the nutrient management practices to compare the chickpea under sequential intercropping systems and sole cropping. For chickpea, only 75 per cent of recommended dose of nitrogen was applied to the both the nutrient management practices. Initial and final plant population recorded higher when chickpea sown as sole (S). Sole planting of chickpea (S) and integrated nutrient management (N2) recorded higher plant height, leaf area, dry matter production plant-1, number of pods plant-1, seed yield, stalk yield and N, P, K uptake than chickpea in sequential intercropping systems (S3 and S5) during both the years. Similarly, when we compare the chickpea in sequential intercropping systems (S3 and S5), these parameters recorded higher when chickpea sown in S5 than S3. Test weight, number of seeds pod-1 and harvest index were not influenced by the either sequential intercropping system nor integrated nutrient management. From the above studies, it can be concluded that when chickpea sown as sequential intercrop with paired row system of pigeonpea resulted the higher growth, yield and nutrient uptake of chickpea than chickpea in sequential intercropped with normal spaced pigeonpea.
