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

Abstract

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
