EFFECT OF FERTILIZERS ON GROWTH AND YIELD OF SUNFLOWER

The experiment was conducted to study the effect of fertilizers on
growth and yield of BARI sunflower-2 during January to April 2018. Six
fertilizers combination was used as treatments, viz., T0 (No fertilizer), T1 (Urea, TSP and
MoP), T2 (Urea, TSP, MoP and Gypsum), T3 (Urea, TSP, MoP,
Gypsum and Zinc sulphate), T4 (Urea, TSP, MoP, Gypsum, Zinc sulphate
and Boric acid) and T5 (Urea, TSP, MoP, Gypsum, Zinc sulphate, Boric
acid and Magnesium sulphate). The doses of different fertilizers were 180 kg
Urea, 160 kg TSP, 150 kg MoP, 150 kg Gypsum, 8 kg zinc Sulphate, 10 kg Boric
acid, 80 kg Magnesium Sulphate and 8 tonnes of cowdung per hectare. In all the treatment’s
statistically increased plant height, leaf length, leaf width, head diameter,
head weight, 1000 seed weight and seed yield over control. The highest plant
height at 25, 45 and 120 days after sowing were 2.90, 11.99 and 120.01 cm,
respectively. The highest head diameter, head weight, 1000 seed weight and seed
yield were 17.08 cm, 105.60 gm, 68.09 gm and 2.39 t/ha, respectively. The
results revealed that different growth parameters and yield of sunflower (BARI
sunflower-2) where increase gradually with combined application of fertilizers.
