Abstract:

A Field experiment was conducted at Main agriculture research station, University of Agricultural Sciences, Raichur, Karnatka on deep black soil during kharif 2016 to study the yield maximization through in-situ moisture conservation practices in conjunction with nutrient levels in bt cotton. The results of this experiment revealed that there was significant difference in growth and yield attributing parameters with different land configurations and nutrient levels. Ridges and furrows recorded significantly higher leaf area (74.46 dm2 plant-1), total dry matter production (374.55 g plant-1), seed cotton yield (2403 kg ha-1) and harvest index (0.35) over flatbed (71.51 dm2 plant-1, 342.76 g plant-1,1743 kg ha-1 and 0.27, respectively). Among the nutrient levels application of 90:45:45 NPK kg ha-1 (50% N through organic) was recorded significantly higher leaf area (74.06 dm2 plant-1), total dry matter production (369.85 g plant-1), seed cotton yield (2308 kg ha-1) and harvest index (0.33) over other treatments. Among the interactions significantly higher leaf area (77.19 dm2 plant-1), total dry matter production (390.57 g plant-1) and seed cotton yield (2834 kg ha-1) was recorded in ridges and furrows with application of 90:45:45 NPK kg ha-1 (50% N through organic) as compared to other treatment combinations.


Keywords: Nutrient levels, Bt cotton, Land configurations, Ridges and furrows, Broad bed and furrows and flat bed.
