Abstract:
The present investigation entitled “varietal response of Indian bean (Lablab purpureus L.) for biofertilizers” was carried out during kharif season 2020-21 at College farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat, India. There were twelve treatments having the various combinations of varieties (GJIB 2, GJIB 11, GNIB 22, and Arka Jay) along with different biofertilizers (Rhizobium, PSB, Rhizobium + PSB). Treatments were replicated thrice in a randomized block design with factorial concept. The observations were recorded and subjected to statistical analysis as per the standard procedure. Variety GJIB 11 (v₂) registered minimum days taken for 50% germination (4.00), while maximum plant height at 60 DAS (114.68 cm) and at final harvest (166.02 cm), number of branches per plant (28.29), pods per cluster (6.73), days taken for last picking (155.56), yield per plant (306.03 g), per plot (2.82 kg) and per hectare (139.09 q). Whereas, variety GNIB 22 (v₃) was found superior by recording minimum days taken for initiation of flower (41.53), first picking (74.91) and recorded maximum number of clusters per plant (25.44) as well as pickings (9.11). Application of biofertilizer Rhizobium + PSB (b₃) enhanced the plant height at 60 DAS (76.41 cm) and at final harvest (109.93 cm). Whereas, increase number of branches per plant (23.97), cluster per plant (18.39), yield per plant (229.71 g), yield per plot (2.14 kg) and yield per hectare (105.56 q) of Indian bean. The interaction effect of varieties and biofertilizers were found non-significant for all characters.
