Abstract

A field experiment was conducted during rainy  season (kharif) 1992, 1993 and 1994 at Sirsi (Hillzone 9) of
Karnataka to study the effect of lime and phosphorus sources on grain yield of rice under transplanted conditions. The
experiment consisted'of 6 sources of phosphorus and 2 levels of lime. Application oflime @500 kg/ha had significantly
increased yield compared with without lime (control). The combination of rock  phosphate + diammonium phosphate
(50:50) had significantly increased yield (5 205 kg/ha) and was on par with diammonium phosphate alone (4 790 kg/ha)
than rock phosphate (4 690 kg/ha). Net profit (Rs 7 114/ha) was higher in rock phosphate + diammonium phosphate
(50:50) followed by the diammonium phosphate (Rs 5 920/ha) and west was in single superphoshate (Rs 4 651/ha).
