Effect of tillage practices on productivity of wheat (Triticum aestivum L.)

A field experiment was conducted at the research farm of ICAR-Indian Agricultural research Institute, New Delhi during the rabi season 2014-15 to study the effects of various tillage practices on biophysical parameters, yield attributes and yield of wheat in pigeonpea-wheat cropping system. The experiment was conducted in a randomized block design (RBD) replicated thrice. The following treatments were included such as zero tilled permanent narrow bed (PNB), zero tilled permanent narrow bed plus residue (PNB+R), zero tilled permanent broad bed (PBB), zero tilled permanent broad bed plus residue (PBB+R), zero tilled flatbed (ZT), zero tilled flatbed plus residue (ZT+R). The yield attributes viz. plant height, plant biomass, leaf area index (LAI) etc. were significantly influenced with tillage practices. Yield was recorded significantly higher under PBB+R followed by ZT+R, ZT, PBB, PNB+R, PNB and CT
