ABSTRACT
Deep tillage, is performing tillage operations below 20 cm depth, has countless benefits in rain-fed areas but the recent problem in the deep tillage is the loss of nutrients. Various techniques have been studied for declining the loss of nutrients. Therefore, this research was carried out in the University Research Farm, The University of Agriculture Peshawar, Pakistan to find the effect of raised seed bed dimensions and integrated nutrient management on the yield of winter wheat (Triticum aestivum) cultivar (Pirsabak 2015) under deep tillage in silt clay loam (Pedocals) soil during 2019. The levels of planting technique factor were; 0 m high raised seed bed (P1), 10 cm high raised seed bed (P2) and 20 cm high raised seed bed (P3). Compost from domestic residues (C2), a combination of urea with compost (C3), and urea (C4) were compared with control, no N-fertilizer (C1) in integrated nutrient management factor. The result showed that the treatments had a significant effect on the plant height, spike m-2, grains spike-1, grain yield, biological yield, and harvest index. The highest plant height (0.44 m) and spike m-2 (88) were found in the combination of P3 with C2. The highest grain yield (3298 kg ha-1) was recorded in the combination of P2 and C3. The highest biological yield (9144 kg ha-1) was found in P1 with C3. Though the highest grains spike-1 (89), thousand-grain weight (45 g) and harvest index (39.91%) were calculated in the combination of P1 and C4. Almost all the parameters gave the lowest recorded value in the combination of P1 with C1. The research concluded that the combination of compost with urea and raised seed bed are the better option for enhancing the wheat yield under deep tillage.
