An experiment was carried out during kharif and rabi seasons of 2019-20 and 2020-21 at ARI, Rajendranagar, Hyderabad.Â The experiment was laid out in randomized block design (Factorial) with two factors i.e., one with six levels of sequentialÂ intercropping systems of pigeonpea (S1 to S6) and other with two levels of nutrient management practices (N1 and N2 - anÂ integrated approach). Initial and final plant population were recorded at 30 DAS and harvest, respectively. Growth observationsÂ of pigeonpea viz., plant height, leaf area plant-1, dry matter production plant-1 and number of branches plant-1 were recorded atÂ periodical intervals. Initial and final plant population were significantly not influenced by sequential intercropping systems andÂ integrated nutrient management practices. Among the pigeonpea based sequential intercropping systems higher plant height, leaf
area plant-1, dry matter production plant-1, number of branches plant-1 and seed yield were recorded when pigeonpea sown as soleÂ (S1 and S2) than the pigeonpea with sequential intercropping systems (S3, S4, S5 and S6) during both the years. However, higherÂ pigeonpea equivalent yield was recorded in paired row pigeonpea with sweet corn â€“ chickpea (S5). Application of 75 % RDNÂ through fertilizers and 25 % through FYM (N2) recorded higher plant height, leaf area plant-1, dry matter production plant-1, numberÂ of branches plant-1, seed yield and pigeonpea equivalent yield over application of 100 % RDN through fertilizers (N1).
