Effect of paraquat on quality parameters and economics of green gram genotypes (Vigna radiata L. Wilczek)
Author(s): Keerti and Ganajaxi Math
The field experiment was carried out to study the “Effect paraquat on economics, growth and quality parameter of green gram genotypes (Vigna radiata L. Wilczek)” at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The field experiment was laid out in split - split plot design with two main plots (methods of harvesting), three sub plots (genotypes) and two sub sub plots (paraquat spray and control). Result revealed that In both manual and mechanical harvesting of the genotypes, paraquat sprayed treatments recorded significantly lower number of leaves plant-1, dry matter production plant-1 and crop growth rate (7.28 - 7.73, 10.04 - 10.64 g plant-1, 0.020 - 0.031 g dm-2 day-1, respectively) and Significantly higher net return (Rs 40,208 - 43,060 ha-1) and B:C ratio (3.06 - 3.21) was recorded. Application of paraquat as defoliator did not impose adverse effect on germination of seed and its quality (protein content). Main aim of this investigation was to minimize grain losses and quality deterioration. Harvest at the right time and at optimum moisture content.
