Abstract
The present investigation entitled “Studies on effect of intercropping and manurial practices on pod and seed yield of French bean cv. Lakshmi” was carried out at Experimental Farm and Quality Analysis Laboratory, Department of Vegetable Science, Dr Yashwant Singh Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) during Kharif 2022. The experiment was conducted on main crop French bean cv. Lakshmi and intercrops viz., maize var. Local Selection and okra var. P-8 which was laid out in Randomized Complete Block Design with three replications, comprising of seven treatments viz., T1: French bean intercropped with Maize + FYM, T2: French bean intercropped with Maize + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T3: French bean intercropped with Maize + FYM + RDF, T4: French bean intercropped with Okra + FYM, T5: French bean intercropped with Okra + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T6: French bean intercropped with Okra + FYM + RDF and T7 (Control): French bean sole crop + FYM + RDF. Analysis of variance showed significant variations for effect of intercropping and manurial practices on most of the parameters studied. Among different treatments, sole French bean + FYM + RDF (T7) recorded minimum days to 50 % flowering and days to first maturity and maximum number of clusters per plant, number of pods per plant, pod length, pod width, number of seeds per pod, plant height, pod and seed yield (per plant & per hectare), 100 seed weight and protein content. T6 performed best in yield of intercrops, and total French bean pod plus French bean pod equivalent yield as well as total French bean seed plus French bean seed equivalent yield (per plant & per hectare). From the present investigation, it was concluded that French bean cv. Lakshmi intercropped with okra and application of recommended doses of manures and fertilizers (200 q/ha FYM + 50 kg N/ha + 100 kg P2O5/ha + 50 kg K2O/ha) gave the highest yield of French bean pod (109.97 q/ha) and okra (110.18 q/ha) along with maximum net returns per hectare (₹ 4,47,493) and B:C ratio (2.10) and for seed production, it gave the highest seed yield of French bean (11.17 q/ha) and okra (110.18 q/ha) along with maximum net returns per hectare (₹ 4,48,443) and B:C ratio (2.06) under mid hill conditions of Himachal Pradesh.
