Abstract:

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 rock phosphate @ 200 kg ha-1 to the preceding sunhemp recorded significantly higher dehydrogenase activity in soil (16.1 μg TPF g-1 soil day-1) and phosphatase activity (73.24 μg PNP g-1 soil hr-1). Soil application of rock phosphate @ 150 to 200 ka ha-1 to preceding sunhemp recorded higher microbial population of actinomycetes, fungi and nitrogen fixer’s. The phosphorus solubilizers’ population found significant with application of RDF + FYM.
