Abstract
Conventional practices of farming in mountainous and hilly topographic features of Rawalakot Azad
Kashmir-Pakistan accelerate runoff and erosion. To study effect of tillage and integrated nutrient
management practices field study was conducted in 2009. Layout of experiment was split plot with
four main plots of shallow (0-15 cm) and deep tillage (15-30 cm) with residues (wheat straw; 4 Mg
ha-1) and without residues incorporation. Four tillage levels were: S (Shallow tillage), SR (Shallow
tillage with residues; wheat straw @ 4 Mg ha-1), D (Deep tillage) and DR (Deep tillage with residues;
wheat straw @ 4 Mg ha-1). Sub plots were having three fertilizer levels viz. F0 (control), F1
(Recommended rate of inorganic fertilizers at per hectare rate; 120 Kg N-90 Kg P2O5-60 Kg K2O) and
F3 (application of farm yard manure (FYM @ 7692 kg ha-1) + 60 Kg N- 90 Kg P2O5-60 Kg K2O ha-1).
Significantly (p ≤ 0.05) higher wheat grain yield of 2.9 kg ha-1 was obtained under D while wheat
straw yield was statistically similar under all tillage practices. Fertilizer’s level F2 and F3 increased
grain yield and straw yield compare to F0 but between F2 and F3 statistically no difference was
observed. Statistically higher Water Use efficiency (WUE) was obtained for D (4.56 kg ha-1 mm-1)
and lower with S (2.79 kg ha-1 mm-1). Among fertilizers levels F2 gave higher WUE (4.24 kg ha-1 mm-
1
) which is similar to F1 (3.78 kg ha-1 mm-1).
