Influence of levels of Phosphorus and Molybdenum Seed Treatment on Performance of Soybean in Vertisols of Telangana

Abstract

Field experiment entitled “Phosphorus and Molybdenum studies on productivity, quality and soil fertility of soybean – maize cropping system” was conducted during 2018-19 & 2019-20. at the Regional Sugarcane and Rice Research Station, Rudrur, Professor Jayashankar Telangana State Agriculture University situated at an altitude of 286.3. m above mean sea level (MSL) at 180 49’41’ latitude and 78056’45" E longitude, (PJTSAU). The experiment consisted of 16 treatments viz., four levels of phosphorus (0, 30 60, and 90 kg P2O5 ha-1) and four levels of seed treatment with molybdenum (0, 2, 4 and 6 g kg-1 seed) laid out in a randomized block design with factorial concept and replicated thrice. Perusal of mean results of two years indicated that interaction effect of varying levels of phosphorus and molybdenum seed treatment was significant on plant height at harvest. Phosphorus dose of 60kg P2O5 ha-1 + molybdenum seed treatment @ 4 g kg-1 seed produced significantly higher plant height of 98.28 cm .Phosphorus dose of 90 kg P2O5 ha-1 + seed treatment with molybdenum @ 4 g kg-1 seed produced significantly higher number of pods 231.8 simlilar to that produced with 60 kg P2O5 ha-1 at similar level of molybdenum (226) and higher level of molybdenum 6 g kg-1 seed with 60 kg P2O5 ha-1 (225.8). Significantly higher grain yield was recorded at higher level of phosphorus at 90 kg P2O5 ha-1 with molybdenum seed treatment 4 g Mo per kg seed (3397kg ha-1).
