Abstract:
A field experimental trail on groundnut was conducted during Zaid, 2021 at Krishi Vigyan Kendra (KVK), Department of Agronomy, SHUATS, Prayagraj (U.P.). To evaluate the effect of zinc and phosphorus on growth and yield of groundnut. The soil of experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225 kg/ha), available P (19.50 kg/ha), available K (92 kg/ha). The experiment was laid out in Randomized Block Design (RBD) with ten treatments replicated thrice. In the view of this experiment, zinc and phosphorus were applied thrice at different levels (ZnSO4 at 10, 20, 30 kg/ha and P at 20, 40, 60 kg/ha respectively) along with RDF and control plot with RDF alone. Results revealed that growth parameters at 60 DAS and yield parameters at harvest viz: plant height (24.13 cm), number of nodules/plant (180.53), plant dry weight (59.10 g), number of pods/plant (27.53), number of kernels/ pod (2), seed index (39.77 g), shelling percentage (69.90%), pod yield (3 t/ha), seed yield (2.10 t/ha), haulm yield (3.35 t/ha) and harvest index (32.10%) were recorded significantly higher with the application of ZnSO4 30 kg/ha + Phosphorus 60 kg/ha as compared to other treatments.
