Abstract
The objective was to study the effect of soil incorporated potassium sulphate when applied alone and in combination with FYM on the growth and yield of fine rice “Super Basmati”. The experiment was conducted at Kala Shah Kaku during 2010 using RCBD with three replications. The treatments were control (T1 ) where no K2SO4 and FYM was applied , soil application of K2SO4 @ 70Kg ha-1 ( T2 ), FYM application @ 5 t ha-1 (T3 ), FYM application @ 5 t ha-1 + K2O @ 20 Kg ha-1 (T4 ), FYM application @ 5 t ha-1 +K2O @ 40 Kg ha-1 (T5 ). Paddy yield was significantly enhanced when K2SO4 was applied in combination with FYM. Maximum paddy yield (6.11 t ha-1 ) was recorded in T5 while, lowest paddy yield (4.15 t ha-1 ) was found in control. The increase in yield with K2SO4 and FYM application (47.23%) compared to control was an outcome of positive correlation between grain yield and tillers m-2 , grains panicle-1 and thousand-grain weight which ultimately enhanced paddy yield.
