Impact of phosphorus and Sulphur organo mineral fertilizers on growth and yield attributes of green gram (Vigna radiate (L.) Wilczek) on alluvial soil

Abstract

The aims of our study were to enhance plant growth promotion and yield of Green gram crop by various combinations of phosphorus organo-Mineral Fertilizers (P-OMF), Sulphur Organo-Mineral Fertilizers (S-OMF) and recommended doses of fertilizers (RDF) under two year field experiments. The treatment combination (T7) (75%RDF +P-OMF@ 5.0 q ha-1 [email protected] q ha-1) increased 31.68 cm, 9.75 (q ha-1), 22.43 (q ha-1) and 32.58 (g) Plant height, grain yield, stover yield and test weight in 2013-14 year and also 36.68 cm, 10.02 (q ha-1), 22.14 (q ha-1) and 33.23 (g) in 2014-15 year, respectively. Similarly these treatment combinations showed maximum pod length, Number of pods plant-1, Number of seed pod-1, total nodules plant-1, and dry weight of nodules plant-1 (mg). The results showed that the combined application of combination (T7) (75%RDF +P-OMF@ 5.0 q ha-1 [email protected] q ha-1) can be used as efficient fertilizer consortium for Green gram production.
