Description |
The field experiment was conducted at two locations during kharif 2011 and 2012 at Vasantrao Naik Marathwada Krishi Vidyapeeth (VNMKV), Parbhani, Maharashtra and International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh to study the effect of various integrated agronomic practices on hybrids and pure-line varieties of pigeonpea. The genotypes used were three medium maturity group hybrids (ICPH 2671, ICPH 2740 and ICPH 3762) and three pure-line varieties (BDN 711, BSMR 736 and Asha) laid out in split-plot design with three replications in Vertisols. The experimental material was planted in three treatments viz., T1 [75 x 30 cm + 100 kg DAP (basal) + no protective irrigation]; T2 [75 x 60 cm + 50 N:100 P2O5 kg ha-1 (split application: 50% as basal and 50% at 60 days) + two protective irrigations (during mid-flowering and mid-pod development stage)]; and T3 [150 x 30 cm + 50 N:100 P2O5 kg ha-1 (split application: 50% as basal and 50% at 60 days) + two protective irrigations (mid-flowering and mid-pod development stage)]. The results indicated that significantly higher seed yield, biomass and harvest index was recorded in T2 at 3923.9 kg ha-1, 8816.6 kg ha-1 and 30.8%, respectively as compared to T3 (3262.5 kg ha-1, 7670.1 kg ha-1 and 29.8%, respectively) and T1 (2932.3 kg ha-1, 7633.3 kg ha-1 and 27.8%, respectively). Genotype × environment interaction indicated that over the two locations in two years, hybrids recorded higher seed yield as compared to pure-line varieties. However, G3T2 [ICPH 3762 + (75 x 60 cm + 50 kg N:100 P2O5 kg ha-1 (split application at 50% as basal and 50% at 60 days after sowing) + two irrigations (during mid-flowering and mid-pod development stage)] recorded the highest seed yield (4153.6 kg ha-1). Number of pods plant-1 and biomass weight (kg ha-1) showed significant variation in the interaction of environment × genotype × treatment (EGT). E1G3T3 recorded significantly higher number of pods plant-1 (1181.9) followed by E1G3T2 (1026.1) which significantly converted into higher seed yield plant-1 (237.1 g & 240.1 g respectively) while E2G2T2 exhibited significantly greater biomass (11977.9 kg ha-1). Among all the genotypes tested, Hybrid ICPH 3762 recorded highest number of pods plant-1 in T3 in almost all environments.
