Abstract:

A field experiment was conducted in Rabi season of 2016-17 at experimental field of AICRP on Irrigation Water Management, Dr. Rajendra Prasad Central Agricultural University, Pusa (Bihar), India. This experiment was undertaken to study the response of different levels of irrigation on crop growth, yield, biomass and water use efficiency of Rabi maize under different levels of furrow irrigation under different treatments. The experiment was laid out in randomized block design with four treatment, five replication and five irrigations were applied in the main plot. The growing season was divided into three phases: vegetative, flowering and grain filling. The irrigation treatments consisted of all possible combinations of full irrigation or limited irrigation in such that T1 (full/control irrigation), T2 (75% of CI), T3 (50% of CI) and T4 (Rainfed /No Irrigation). The biometric parameters like plant height, stem diameter, number of leaves and canopy spread were significantly superior in treatment T1 (control/full irrigation) compared to other deficit irrigation and rainfed treatments. The biometric parameters like plant height, stem diameter, number of leaves and canopy spread for treatment T1 (control/full irrigation) was 179.80 cm, 29.90 mm, 12 and 87.70 cm respectively. Rabi maize yield was highest for treatment T1 with a value of 11.12 t/ha, followed by treatment T2 (75% of CI) with a value of 10.98 t/ha and lowest for treatment T4 (Rainfed) with a value of 3.35 t/ha. Biomass was highest for treatment T1 (CI) with a value of 24.92 t/ha, followed by treatment T2 (75% of CI) with a value of 24.65 t/ha and lowest treatment T4 (Rainfed) with the value of 7.931 t/ha. The crop yield and biomass were significantly higher for treatment T1 (control/full irrigation) compared to other treatments. The water use efficiency of Rabi maize yield decreased with increase in irrigation level for all treatments of furrow irrigation. Water use efficiency was highest for treatment T3 with a value of 310 kg/ha-cm followed by treatment T2 with a value of 303 kg/ha-cm. The water use efficiency was significantly higher treatment T3 (50% of CI) compared to other treatments. The adapted values of canopy growth coefficient and canopy decline coefficient were 15.4% day-1 and 9.5% day-1 respectively for Rabi maize. The days of emergence, sowing to flowering, senescence and maturity were 6, 60, 142 and 161 days respectively. The adopted values of water productivity (WP) were obtained as 30.7 g m-2. The harvest index was obtained as 48%.
