Impact of NPK, macronutrients and micronutrients on growth and yield parameters of chilli (Capsicum annuum L.) Pusa Jwala

Abstract

The present investigation during autumn winter season 2022-2023 with the aim of to study the effect of NPK and micronutrients on growth of chilli, to study the effect of NPK and micronutrients on fruit yield of chilli, to study about cost benefit ratio. The experiment was laid out in RBD considering nine treatments with three replications. Different combination of treatment T1 Control (NPK), T2 NPK (100:40:40 kg/ha), T3 NPK (100:40:40 kg/ha) + Calcium (30 kg/ha), T4 NPK (100:40:40) kg/ha + Sulphur (60 kg/ha), T5 NPK (100:40:40) kg/ha + Iron (12 kg/ha), T6 NPK (100:40:40) kg/ha + Calcium (30 kg/ha) + Sulphur (60 kg/ha), T7 NPK (100:40:40) kg/ha + Sulphur (60 kg/ha) + Iron (12 kg/ha), T8 NPK (100:40:40) kg/ha + Calcium (30 kg/ha) + Iron (12 kg/ha), T9 NPK (100:40:40) kg/ha + Calcium (30 kg/ha) + Sulphur (60 kg/ha) + Iron (12 kg/ha). The results showed that application 50% flowering (41.00), no. of primary branches/plant (4.00), no. of secondary branches/plant (7.5), plant height (85.003), Leaves/plant (109.00), leaf area/plant (115.00), Fruit length (9.250), fruit circumference (14.753), pedicle length (3.50), Average fruit weight (45.00), no. of fruit/plant (124.00), total yield/plant (0.400), benefit cost ratio (1.58) was observed with the treatmentT9 NPK (100:40:40) kg/ha + Calcium (30 kg/ha) + Sulphur (60 kg/ha) + Iron (12 kg/ha).
