| dc.description.abstract | A field experiment was conducted at the Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar, District U. S. Nagar (Uttaranchal) to evaluate the effect of puddling on soil properties and performance of rice crop. The experiment was laidout in Split plot design with five puddling levels viz., 1 pass (PR1), 2 passes (PR2), 3 passes (PR3), 4 passes (PR4) and 5 passes (PR5) of rotavator as main plot treatments and residue incorporation (RI) and residue removal (RR) as subplot treatments in four replications. Results showed that puddling raised rice yield upto 4 -passes of rotavator but greatly altered soil physical properties which may not be advantageous to the following non-rice crop. Puddling significantly increased puddling index (58 to 81 per cent),and bulk density (1.43 to 1.57Mg/m3) and decreased porosity (45.94 to 40.46 percent), infiltration rate (20.86 to 9.25mm/d) and saturated hydraulic conductivity (21.16 to 13.39mm/d). The grain yield of rice (6237 kg/ha) was maximum under 4-passes of rotavator but was statistically equal to that obtained under 3-passes of rotavator. The lowest grain yield (5540 kg/ha) was observed under 1-pass of rotavator | en_US |
