Abstract


The growth and yield promotion of mungbean in response to the use of 2, 4-Dichlorophenoxy acetic acid (2, 4-D) was investigated through a pot study which was arranged in the wire house of Institute of Soil and Environmental Sciences, University of Agriculture Faisalabad. The study was comprised of five treatments and three replications (control, 0.2 ppm 2, 4-D, 0.5 ppm 2, 4-D, 0.8 ppm 2, 4-D, and 1 ppm 2, 4-D). The suggested dose of Nitrogen, Phosphorus and Potassium (NPK) was applied at the amount of 20, 60 and 25 kg ha-1 added as Urea, DAP and SOP, respectively at sowing time. The data regarding growth (plant height, root and shoot length, root and shoot fresh and dry weight, and total biomass), yield (grain weight, number of grains plant-1) and NPK analysis in plants and soil was recorded and statistically analyzed. The response of exogenous application of 2, 4-D was significant at all levels in improving the performance of all the growth parameters and yield as compared to untreated control treatment. Maximum performance of all the parameters was recorded at 0.8 ppm application of 2, 4-D. As the concentration of 2, 4-D increased the development of plants also showed positive effect but up to 0.8 ppm application after that it started to decrease which showed that at higher concentrations 2, 4-D acts as growth retardant.
