Abstract:
The aim of this research was to determine the effect of levels of Phosphorus and Potassium on growth, yield and economics of blackgram (Vigna mungo L.). A field experiment was conducted during kharif 2020, at prakasam Krishi Vigyan Kendra (KVK), Jayaprakashnagar, Jammikunta mandal, Karimnagar, Telangana. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.83), medium organic carbon (0.62%), available low N (197.12 Kg/ha), available medium P (31.21 Kg/ha) and available medium K (198.71 Kg/ha). The Observations of Ten treatments were replicated thrice in a Randomized Complete Block Design the finding shows that growth and yield attributes viz. The result showed that higher plant height (38.17 cm), maximum number of branches per plant (5.93), highest number of nodules per plant (15.73), maximum dry weight (8.63), maximum number of pods per plant (20.13), highest number of seeds per pod (6.20), test weight (33.60), seed yield (1456.67 kg/ha), Stover yield (3086.67 kg/ha), harvest index (32.06) and relative growth rate (0.013) were recorded significantly with the application of 40 kg/ha phosphorous + 30 kg/ha potassium. However Highest crop growth rate (7.90) was recorded with 40 phosphorous kg/ha + 30 potassium kg/ha. However highest gross return (80,191 INR/ha), net return (56391 INR/ha), and Benefit: cost ratio (2.36) was recorded with the application of 40 kg phosphorous per hectare + 30 kg of potassium per hectare.
