Abstract
Aim:
This study was carried out to find the optimum fertilizer requirement and
best planting method for higher productivity and profitability of Indian
mustard.
Methodology: A field trial was performed during the rabi season
of 2019-20 on a sandy-loam soil at Agricultural Farm, Palli Siksha Bhavana
(Institute of Agriculture), Visva-Bharati, Sriniketan, Birbhum, West Bengal.
The treatments comprised of three methods of sowing, i.e., transplantation,
broadcasting, and line sowing in the main plot and four nutrient managements,
i.e., 60:30:30, 70:35:35, 80:40:40, and 90:45:45 (N: P2O5:K2O
kg ha-1) in a subplot and replicated thrice in a split-plot
design. Growth economics parameters were evaluated.
Results:
Transplanting method with the nutrient management 90 kg N, 45 kg P2O5,
and 45 kg K2O ha-1 was significantly superior in terms
of growth attributes, yield parameters, productivity, and profitability over
other methods of sowing and nutrient management in lateritic soil of West
Bengal. The transplanted mustard crop produced higher yield because it got
the longest reproductive period and required nutrient level, i.e., 90 kg N,
45 kg P2O5, and 45 kg K2O ha-1.
Interpretation: Finding
appropriate method of sowing under different nutrient levels can be done
using growth, yield attributes, and yield. Yield and profitability were found
maximum under 90 kg N, 45 kg P2O5, and 45 kg K2O ha-1
over other nutrient levels and transplanting method of sowing of Indian
mustard was better than broadcasting, and line sowing method in the present
experiment under the lateritic soil of West Bengal.
Key words: Indian mustard,
Laterite soil, Nutrient management
