A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to determine the “Effect of different levels of potassium and zinc on growth, yield and economics of summer groundnut (Arachis hypogaea L.)”. To study treatments consisting of three levels of Potassium (30,40,50 kg/ha) and three levels of Zinc (10, 15, 20 kg/ha). There were 10 treatments, each of which was replicated three times and laid out in a random block design. The results showed that treatment 9 [Potassium (50kg/ha) + Zinc (20kg/ha)] recorded significantly higher plant height (29.5 cm), higher number of nodules/plant (64.1), higher dry weight (47.30 g). Whereas, maximum number of pods/plant (28.1), maximum number of kernels/pod (2), higher seed index (40 g), higher seed yield (2.31 t/ha), maximum haulm yield (3.74 t/ha) and higher harvest index (32.30 %) was recorded in treatment 9 [Potassium (50kg/ha) + Zinc (20kg/ha)]. Similarly, maximum gross return (1,34,970.00 INR/ha), higher net return (93,469.00 INR/ha) and highest benefit cost ratio (2.25) was also recorded in treatment 9 [Potassium (50kg/ha) + Zinc (20kg/ha)] as compared to other treatments.
