IMPACT OF MULCHING AND ANTI-TRANSPIRANTS ON PHYSIOLOGICAL PARAMETERS AND YIELD OF SOYBEAN
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 63
Abstract
The experiments were carried out during successive kharif season of 2012 - 2014 to investigate the effects of straw mulch and anti-transpirants on physiological parameters and yield of soybean at Millet Breeding Station, Tamil Nadu Agricultural University, Coimbatore. The experiment treatments were arranged in split plot design with four replications. The mulching practices viz., Bajra straw mulch and without mulch were formed the main plot and anti-transpirants viz., Magnesium carbonate (0.5%), Glycerol (5%), Sodium carbonate (2%), Potassium nitrate (1%) and water spray constituted to sub plot. Results showed that enhanced physiological characteristics obtained from bajra straw mulch @ 5 t/ha, while anti-transpirant of potassium nitrate (1%) sprayed at 50% flowering stage which was on par with magnesium carbonate (0.5%) and glycerol (5%). The combined treatments of straw mulch with foliar spray of potassium nitrate (1%), sprayed at flowering stage improved the physiological and yield parameters of soybean. Water stress caused of decreases yield in soybean, but applied of mulches and anti-transpirant materials caused decrease of negative effects of water stress in our experiment and increased values of traits.
