Description |
Three field experiments were conducted at RARS, Bijapur, to study the a) effect of tank silt+crop residue in set furrows and row spacing on pearlmillet-sunflower sequence cropping system, b) effect of green leaf manure+crop residue in set furrows on pearlmilletsunflower sequence cropping system in Vertic-Inceptisol and c) effect of gravel sand, crop residue in set furrows on sunflower–rabi sorghum + chickpea cropping system in Vertisols under dryland condition during 2004-05, 2005-06 and 2006-07. All the experiments were laid out in randomized block design. Pearlmillet equivalent yield was significantly higher with the application of tank silt+CR in set furrows with wider row spacing (4135 kg/ha) than farmers’ practice (1995 kg/ha) and was on par with the tank silt+crop residue application in set furrows with paired row planting of 45-90-45cm and 45-135-45cm (4000 kg/ha and 4090 kg/ha, respectively). Incorporation of GLM+CR+100 per cent RDF in set furrows registered significantly higher pearlmillet equivalent yield (3482 kg/ha) as compared to other treatments. However, it was on par with incorporation of GLM+CR+50 per cent RDF+50 per cent FYM in set furrows (3321 kg/ha). Application of tank silt, green leaf manures and crop residue in set furrows improved the soil moisture, soil fertility and economic status in Vertic-Inceptisol. Rabi sorghum equivalent yield was significantly higher in sunflower-rabi sorghum+chickpea (2:4) sequence cropping system under set row cultivation with crop residue (5696 kg/ha) as compared to rest of the treatments. Incorporation of crop residue in set furrows increased the available soil moisture and improved the soil fertility and economic status. The set row cultivation reduced the runoff and soil loss. The overall effect on water balance study provides a lead for assessing the carrying capacity of the system for macro level planning. |
