tailieunhanh - Effect of phosphorus management through rock phosphate application to preceding crops on yield of groundnut and soil microbial population under organic condition

Field experiment was carried out during 2014-15 and 2015-16 at Main Agricultural Research Station, UAS, Raichur to study the impact of varied levels of rock phosphate application to preceding sunhemp and bajra crops on growth and yield of groundnut [Arachis hypogaea (L.)]. The two years pooled data indicated that soil application of higher levels of rock phosphate at 150 and 200 kg ha-1 to preceding sunhemp (1200 and 1226 kg ha-1 respectively) and 200 kg ha-1 to preceding bajra (1159 kg ha-1 ) recorded significantly higher kernel yield of groundnut and these treatments were at par with treatment receiving RDF + FYM (1253 kg ha-1 ) to both bajra and groundnut crops in the system. |
