Abstract:
A field experiment was conducted at AHRS, Kathalagere, during kharif 2014, to study the effect of different sources of phosphorus with and without PSF on release of available phosphorus and its influence on growth and yield of rice. The effect of different sources and levels of phosphorus @ 40, 50 and 60 kg ha-1 P2O5 as rock phosphate applied in the form of nutriphos with or without PSF were tried along with single super phosphate in a randomized complete block design comprising eight treatments replicated thrice.
A field experiment was conducted at AHRS, Kathalagere, during kharif 2014, to study the effect of different sources of phosphorus with and without PSF on release of available phosphorus and its influence on growth and yield of rice. The effect of different sources and levels of phosphorus @ 40, 50 and 60 kg ha-1 P2O5 as rock phosphate applied in the form of nutriphos with or without PSF were tried along with single super phosphate in a randomized complete block design comprising eight treatments replicated thrice.
The highest value for nitrogen, phosphorus, calcium and magnesium was recorded (149.38,72.59kg ha-1,4.38, 3.58 cmol (p+) kg-1, respectively) in the treatment which received 50 kg ha-1 P205 through rock phosphate applied in the form of nutriphos + PSF and lowest values of available nutrients were recorded where treatment (T3) where 40 kg ha-1 P2O5 through rock phosphate in the form of nutriphos. Positive and significant correlation was observed between uptake of nitrogen, phosphorus and potassium and grain yield (r=0.933**, 0.876** and 0.854**respectively). Similar results were found by Ravindra and Ananthanarayana (1999) and Saavedra and Delgado (2005).
