ABSTRACT
A thrice replicated field trial was conducted during summer season to evaluate sources and methods of phosphorus application on performance and production potential of rice and physico-chemical properties of soil. The experimental findings revealed that maximum growth attributes viz., plant height and dry weight, number of panicle (548.0 m-2), number of grain panicle-1 (90.5) and test weight (24.5 g) grain yield and straw yield (46.60 and76.60 q ha-1) and production efficiency (43.15 kg day-1 ha-1), phosphorus content in grain (0.34 %) and straw (0.16 %) as well as their total uptake (22.02 kg ha-1) as compared to res of the treatments and soil available nutrients viz., NPK were significantly noticed with the application of 45 kg basal + 15 kg at tillering ha-1 P2O5 through SSP. Meanwhile, it had also improved physical properties of soil, besides maintaining PUE viz., agronomic efficiency (31.80 kg/ha), partial factor productivity (72.00), recovery efficiency (12.32 %) and physiological efficiency (584.57) as compared to rest of the treatments.
Key words :
