Abstract

A pot experiment on strawberry cv. ‘Chandlar’ conducted in a horticulture garden at Kanpur, Uttar Pradesh during winter season of 2014-15. The treatments consisted 8 levels of NPK fertilizers viz., F0- control, F1 – N50P30K30, F2 – N100P60K60, F3 – N150P80K80, F4 – N200P100K100, F5 – N250P120K120, F6 – N300P140K140 and F7 – N350P160K160 kg/ha. Cutting produced through runners were transplanted on 21.11.2014 in pots which continued till end of March, 2015. The results revealed that NPK dose of 250 Kg N + 120 Kg P2O5 + 120 Kg K2O/ha was proved to be the optimum with highest values of flower/plant (18.66), fruits/plant (13.93), fruit length (4.02cm), fruit diameter (2.92 cm), fruit weight (15.00 gm), fruit yield per plant (208.88 gm) and quality parameter viz., TSS (10.41 %), total sugar (5.93 %) and vitamin ‘C’ (54.20 mg/g) against their lowest values of 7.13 fruits/plant, 2.71 cm fruit length, 2.05 cm fruit diameter, 10g fruit weight, 71.25 g/plant fruit yield, 7.03 % TSS, 4.86 % total sugar and 49.75 mg/g vitamin ‘C’ recorded in the control treatment of no NPK fertilizers. Fruit acidity was estimated lowest of 0.70 % with N250P120K120 kg/ha against highest of 0.85 % without NPK application. Thus, N250P120K120 kg/ha NPK level was proved optimum for higher yield and quality of strawberry fruits in central Uttar Pradesh condition.
