Effect of nutrient management practices on growth, yield and economics of cotton crop in west central table land zone at Bargarh district of Odisha

Abstract

A field experiment was conducted at the farmer’s field of Bargarh district of Odisha in kharif, 2023 under the demonstration programme of Krishi Vigyan Kendra, Bargarh to study the “Effect of nutrient management practices on growth, yield and economics of cotton crop in west central table land zone at Bargarh district of Odisha”. The treatments were taken as Farmer’s practice (FP) on improper nutrient management and recommended practice (RP) on STBF + one spray of 2% urea and one spray of 1% urea + 1% MgSo4 during flowering to boll development stage. Each treatment replicated for 10 times with randomized block design. The results concluded that the application of nutrient management practices (RP) as STBF with one spray of 2% urea and one spray of 1% urea plus1% MgSo4 during flowering to boll development stage gives the higher boll weight (3.41 g) with higher no of bolls/plant (22) and no of bolls/m2 (101) over the FP. The plant height of the cotton crop was increased by the nutrient management practices as compared to the FP at 30 DAS (31.68 cm), 60 DAS (56.32 cm), 90 DAS (76.39 cm), 120 DAS (103.28 cm) and 150 DAS (123.68) respectively. The cotton crop significantly increased the yield (14 q/ha) over FP with increasing in net return (Rs. 42,220/-) with B:C ratio (1.89) respectively. The RP of nutrient management practices in cotton crop can be recommended to the farmers for better yield and income.
