A field experiment was conducted under loamy sand soil during two consecutive rabi seasons of 2014-15 and 2015-16 at Agronomy Farm, S.K.N. of College of Agriculture, Jobner, India. The treatments comprising five irrigation scheduling methods viz. Irrigation at critical stages (I1), 0.9 IW/CPE ratio (I2), 0.6 IW/CPE ratio at vegetative phase + 0.8 IW/CPE ratio at reproductive phase (I3), 0.6 IW/CPE ratio at vegetative phase + 1.0 IW/CPE ratio at reproductive phase (I4) and 0.8 IW/CPE ratio at vegetative phase + 1.0 IW/CPE ratio at reproductive phase (I5) were assigned in main plots and four does of organic manures i.e. Control (M0), FYM at 15 t/ha (M1), VC at 6 t/ha (M2) and FYM at 7.5 t + VC at 3 t/ha (M3) were applied in sub plots and replicated four times in split plot design. Wheat variety “Raj-4037” was used as a test crop. Results indicated that irrigation applied at 0.9 IW/CPE ratio recorded the maximum values of grain yield and soil moisture parameters (Moisture content before irrigation and 1/3 bar) and proved significantly superior over I1, I4 and I3. The highest moisture depletion pattern from soil was obtained with I2. Results also indicated that application of FYM at 7.5 t + VC at 3 t/harecorded significantly higher grain yield, quality parameters (NPK content and uptake) and soil moisture parameters (Moisture content before irrigation and 1/3 bar) which is found at par with M2 proved superior over rest of the treatments. The highest moisture depletion pattern from soil was obtained with M0. Scheduling of irrigation to wheat at 0.8 IW/CPE at vegetative phase + 1.0 IW/CPE ratio at reproductive phase and application of FYM at 7.5 t + VC 3 t/ha is recommended as this practice brought about significantly higher yield, nutrient content and uptake and moisture content. |
