Abstract

During Summer (zaid) of 2021, the current study conducted at CRF (Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P). The experiment used a RBD (Randomized Block Design) with 3 replications. There are 9 treatments used, each with distinct levels of spacing and Zinc applied.  The agricultural field was found to be uniformly sandy loam with neutral pH (7.4). The treatments consisted of Zinc levels at 10 kg/ha, 12.5 kg/ha and 15 kg/ha and spacing at 25 × 10, 30 × 10 and 35 × 10 whose effect is observed in Groundnut (Var – K6). The treatment 6 with (Zn 15 kg/ha + 30×10) recorded significantly maximum in plant height (40.36 cm), number of nodules/plant (49.43), plant dry weight (21.88 g). The treatment 6 with (Zn 15 kg/ha + 30×10) also recorded significantly higher in yield attributes viz., pods/pant (27.72), kernels/pod (1.92) and seed index (100 seed weight) (39.21 g), pod yield (2773.30 kg/ha), seed yield (1494.67 kg/ha), Haulm yield (5907.67 kg/ha), harvest index (20.18%), oil content (48.26%). The treatment 6 with (Zn 15 kg/ha + 30×10) also recorded significantly the maximum cost of cultivation (50,449.50 INR/ha), gross return (119218.55 INR/ha), net return (68769.05 INR/ha) and B: C ratio (1.36).

Keywords: Groundnut, zinc, spacing, yield, oil content, economics
