Abstract

Various tillage operation and seed rate could be operated to optimize spatial distribution and plant growth. Thereby
enhancing WUE, Sunlight, soil available nutrients and yield of wheat on sustainable basis. To evaluate response of wheat
yield and yield components to different tillage practices (i.e. 3 Times Chisel Plough + 2 Times Rotavator (40cms), 3 Times Mould
Board Plough +2 Times Rotavator (30cms), 2 Times Disc harrow + 2 Times Rotavator (20cms),1 Time Cultivator + 1 Time
Rotavator (10cms) and seed rates (i.e. 70, 85,100,115,130,145,160,175 kg ha-1
). The research experiment was conducted in
randomized complete block Design with split plot arrangement with three replications at Agronomy Research Farm, The
University of Agriculture Peshawar during winter 2014-2015. Significant effect of different tillage practices on spike weight,
grains spike-1
, biological and grain yield were recorded. Highest spike weight (2.92 g), grains spike-1
(41), grain yield (3418
kg ha-1
), were recorded from treatment of Two Time Disc Harrow + Two Time Cultivator (20 cm). Highest biological yield
(10141 kg ha-1
) was observed from 3 Times Mould Board Plough + 2 Times Rotavator (30cms). Maximum weeds dry weight m2
(32.8 g) was recorded with tillage practices 3 Chisel Plough+2 Rotavator (40 cm). Seed rates also showed significant effect
on spike weight, grains weight spike-1
, grains per spike, weeds dry weight m-2
, grain yield and biological yield. Maximum spike
weight (2.88 g),grains weight spike-1
(1.26 g), grains per spike (42), grain yield(3573 kg ha-1
),were observed with seed rate of
115 kg ha-1
. Highest biological yield (10348 kg ha-1
) were recorded from seed rate 175 kg ha-1
. Maximum weeds dry weight
m-2
(30.8 g) was observed with seed rate 70 kg ha-1
. It is concluded that tillage practices 2 Times Disc harrow + 2 Times
Rotavator (20cms) and seed rate of 115kg ha-1 produced maximum yield of wheaT
