Abstract :
The experiment was conducted at Rampur Research Farm Rampur, Dehradun, Uttarakhand, India during Nov., 2013 to April, 2014 to study the effect of planting techniques and irrigation levels on growth and yield of wheat (UP-2584). Irrigation was scheduled as per treatment based on IW (Irrigation Water): CPE (Cumulative Pan Evaporation) ratio and on critical growth stages (CGS). The treatments comprising three irrigation scheduling i.e. l1 (irrigation at IW: CPE 0.90), l2 (irrigation at IW: CPE1.20) and l3 (irrigation at Critical Growth Stages) and five planting techniques i.e. Flat bed (Conventional). Raised bed, top 45 cm with two rows (RB 45/15). Broadcast seeding then making raised bed, top 45 cm (MRB 45/25). Broadcast seeding then making raised bed, top 60 cm (MRB 60/25). Broadcast seeding then making raised bed, top 80 cm (MRB 80/25). Data on agronomic traits like germination, numbers of tillers per m2, numbers of active leaves, dry matter accumulation, plant height, grain weight, 1000-grain weight, grain number/ear, number of fertile and sterile spikelet’s/spike, grain yield, straw yield, biological yield and harvest index was recorded. Result showed that irrigation schedule at IW: CPE 1.20 recorded significantly highest grain yield (48.3 quintal/ha), respectively compared to rest of treatment. Consumptive water use efficiency was recorded in IW: CPE 0.90 significantly highest (28.4 kg/ ha-cm), respectively as compared to IW: CPE 1.20 and CGS. Numbers of tillers/m2, dry matter accumulation (g/m2), root weight density, 1000-grain weight in CGS levels was significantly highest over rest of the treatments.
