| Popis: | A field experiment was carried out at four locations i.e. Ludhiana, Bathinda, Faridkot and Gurdaspur to study the influence of diverse environments on symbiotic traits, thermal requirements, growth in terms of plant height (cm) and yield (kg/ha) of pigeonpea [Cajanus cajan (L.) Millsp.] genotypes under different agroclimatic zones of Punjab. Results indicated that crop sown on 15 May recorded the higher grain yield than later sowing dates of 1 June and 15 June at all the locations; 15 May sowing provided 23.3, 22.1 and 46.7% higher grain yield over 1 May, 1 June and 15 June sowing, respectively. Early sown crop acquired higher agro-climatic indices than delayed sowings. The crop sown on 15 May provided the maximum gross returns, net returns and B:C ratio as evident from the additional income of Rs 13599, 13040 and 22865 Rs/ha over 1 May, 1 June and 15 June sowing, respectively. Among the genotypes, AL 201 at Ludhiana and Gurdaspur, AL 1578 at Bathinda and PAU 881 at Faridkot resulted in the highest grain yield and maximum returns. The genotype AL 201 took more days to 50% flowering and maturity at all the locations. It can be concluded that 15 May is the optimum sowing date and AL 201 and PAU 881 are the promising genotypes for providing high productivity of pigeonpea under different agroclimatic zones of Punjab. |
