ABSTRACT
Field experiment was carried out during the Kharif 2016 at Main agriculture research station, University of Agricultural Sciences (UAS), Raichur, to study the effect of land configuration, nutrient management treatments and their integration effect on yield(%) and soil moisture content(%) at sowing, 90 DAS and at final picking of varied depths such as 0-15cm, 15-30cm, 30-45cm and 45-60cm. Significantly higher seed cotton yield was recorded with ridges and furrows (2403 Kg/ha) as compared broad bed and furrows (2222 Kg/ha) and flat bed sowing (1743 Kg/ha). Ridges and furrows was recorded higher soil moisture content at 0-15cm, 15-30cm, 30-45cm and 45-60cm depth of soil at sowing (28.44, 28.46, 29.27 and 29.61 % , respectively ) and throughout cropping season. Nutrient levels with application of 90:45:45 NPK kg ha-1 (50% N through organic) was recorded higher seed cotton yield (2308 kg ha-1) and soil moisture content over other treatments. Among the interaction ridges and furrows with application of 90:45:45 NPK kg ha-1 (50% N through organic) recordedhigher seed cotton yield (2834 kg ha-1) and more moisture content over other treatment combinations.
Key words: Nutrient levels, Bt cotton, Land configurations, Moisture Content, Ridges and furrows, Broad bed and Furrows and flat bed.
