The solutions of K2SO4 @ 200 L ha-1 at set concentrations were sprayed twice (on 15 and 7 d before pollination) with a hand sprayer to the respective treatments.
Foliar application of 2% and 5% K2SO4 significantly improved the grain number as compared to 0 K plants under drought treatment.

Present studies were, hence, undertaken to test the hypothesis whether the low-priced foliar KNO3 application on fine basmati rice can equally or increasingly affect the growth, yield and economic returns in comparison to conventional soil incorporated K2SO4.
The treatments were as T1 = soil application of K2SO4 @70 Kg ha-1, T2 = foliar application of KNO3 @0.
Total N was determined by sulphuric acid digestion using Se, CuSO4 and K2SO4 as catalyst.
K2SO4 raises the boiling point of acid, whereas, CuSO4 serves as catalyst and FeSO4 helps in avoiding any bumping if present.
The CPM per treatment calculation and extra quantity of phosphorus and potassium were applied at the time of sowing as TSP (Triple Super Phosphate) and K2SO4 (Potassium Sulphate), respectively.
Comparative rice yield and economic advantage of foliar KNO3 over soil applied K2SO4.
1 gm) was digested in concentrated H2SO4, K2SO4, CuSO4 and Se and HgO in digestion tube and (50-375oC) digested the sample for 3-4 hours and greenish colour was obtained i.
The samples were digested with concentrated sulfuric acid in the presence of digestion mixture containing K2SO4, CuSO4 and FeSO4 (90: 10: 1).
Full dose of P and K as SSP and K as K2SO4 (SOP) respectively, was applied, while half of the N as urea was applied at the time of sowing.
