Response of Chickpea (Cicer arietinum L.) Productivity. Under Different Irrigation Frequencies and Mulching

      Аннотация: A field experiment was conducted during rabi season from 13th October, 2017 to 19thFebruary, 2018 at plasticulture farm of CTAE Udaipur, (Rajasthan).The net water requirement of chickpea crop was found to be 70 mm under single irrigation at pre-sowing only, 144 mm in double irrigation at pre-sowing with flowering stage and 216 mm in triple irrigation at pre-sowing, flowering stage and pod filling stage. Mulching and irrigation frequencies significantly influenced the growth and yield parameters like maximum plant height (77.67 cm), number of primary branches/plant (28.50),number of pods/plant (37.33), average weight of pod (0.32 gm), number of seeds/pod (1.85), seed weight/pod (0.21 gm), yield/plant (9.96 gm), yield/plot (3.22 kg) and yield/ha (20.29 q) at harvest The maximum yield (20.29 q/ha) was recorded in treatment T5 i.e. combination of M1 (PPWM) and I2 (double irrigation) Further maximum net income of Rs 22354/ha with output: input ratio of 1.49 was also recorded under the same i.e. treatment (i.e. T5). However, the highest water use efficiency of 2.553 kg/ha-cm was recorded in treatment T4 i.e. combination of M1 (PPWM) and I1(single irrigation).
