Mustard seed (Brassica nigra) is a crucial oilseed crop extensively cultivated in several countries, especially in South Asia. Enhancing seed planting techniques is essential to optimize crop output and overcome the challenges faced by farmers. Traditional manual planting methods are inefficient and time-consuming, creating obstacles to overall agricultural productivity. To address this issue, a field test and evaluation of a seven-row inclined plate planter for mustard cultivation were conducted. Precision planting, which involves accurate seed placement at desired intervals, is vital for maximizing crop productivity. The study encompassed a comprehensive analysis of soil parameters, including soil type, moisture content, bulk density, and cone index. Various operational parameters such as seed spacing, row spacing, and ground wheel slip were evaluated. The economic aspects, including cost analysis, breakeven point, payback period, and benefit-cost ratio, were considered to assess the financial feasibility of the tractor-operated planter.

Calibration results revealed variations in seed rates among different rows and hopper capacities, impacting seed placement uniformity. Additionally, the study examined seed breakage under different operational parameters, emphasizing its influence on germination rates. Field performance data included soil moisture (12.61%), bulk density (1.45 g/cc), and field efficiency (82.30%), offering insights into real-world planter operation. The cost analysis determined a favorable economic outlook, with a benefit-cost ratio of 1.2, signifying the economic viability of machine harvesting compared to manual methods.
