A field experiment was conducted to investigate performance of field bean with varying spacing and fertilizer levels at ZARS, UAS, GKVK, Bengaluru. The experiment consisted of two factors i.e., spacing and fertilizer each at four different levels. Among spacing levels, growth parameters such as number of branches (6.9), number of leaves (17.5), leaf area (906.5 cm² plant-1), dry matter production (31.1 g plant-1) were recorded significantly higher in 60 cm × 30 cm spacing (S4 ). Similarly yield parameters, pod length (5.4 cm), number of seeds pod-1 (4.2), number of pods plant-1 (25.3), seed yield plant-1 (16.1 g) were found significantly higher in 60 cm × 30 cm spacing whereas, higher seed yield (848.7 kg ha-1) was recorded in 45 cm × 15 cm spacing (S1 ). Among different fertilizer levels higher number of branches (6.8), number of leaves (16.5), leaf area (897.2 cm² plant-1), dry matter production (28.6 g plant-1) and higher yield parameters namely pod length (5.4 cm), number of seeds pod-1 (4.22), number of pods plant-1 (24.7) and seed yield (764.6 kg ha-1) were recorded in 150 per cent RDF application (F4 ). These parameters were found on par with 125% RDF (F3 ). Among the treatment combinations between spacing and fertilizer levels S1F4 (45 cm × 15 cm spacing and 150% RDF) recorded higher seed (918.2 kg ha-1) yield. Among spacing levels higher nitrogen, phosphorus and potassium uptake was recorded (53.20, 6.78 and 48.52 kg ha-1, respectively) with spacing of 45 cm × 15 cm. Among different fertilizer levels higher nitrogen, phosphorus and potassium uptake (52.36, 6.68 and 48.17 kg ha-1, respectively) was recorded in application of 150% RDF level compared with other levels of application.
