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 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. Number of root nodules and dry weight of root nodules at peak growth stage (90 DAS) recorded with the application of RDF + FYM to both bajra and groundnut crops in the system were significantly higher over all other treatments but it was on par with rock phosphate application @ 150 and 200 kg ha-1 to preceding sunhemp and rock phosphate @ 200 kg ha-1 to preceding bajra. Bacterial and Actinomycetes population found significantly higher at 60 and 90 DAS with higher levels of rock phosphate application to preceding sunhemp compared to preceding bajra crop whereas population of Phosphorus solubilizers was found significant with the application of RDF + FYM to both the crops in the system over all other treatments except treatments receiving rock phosphate @ 50 and 100 kg ha-1 to preceding bajra crop at 60 DAS.
