Effect of Different Levels of Irrigation on Plant Growth and Yield of Mango cv. Langra

Artificial application of water to the effective root zone of crops on the appropriate time gives significant results on plant growth and fruit yield in mango. In order to understand the effects of soil moisture content in mango, trial was conducted under the experimental area of BAU, Sabour, Bhagalpur during 2020-21 using five treatments i.e. T1-[Control], T2-[Water requirement at 25% of EP], T3-[Water requirement at 50% of EP], T4-[Water requirement at 75% of EP], T5-[Water requirement at 100% of EP] in a randomized complete block design (RCBD) with four replications. Treatment T4-[Water requirement at 75% of EP]significantly performed better in respect of increase in plant height of 0.24 m, number of 695.00 fruits per plant and yield of 193.23 kg per plant ( 19.32 t/ha). The maximum increase in plant spread such as East-West and North-South direction were 0.25m and 0.23m, respectively, and the maximum canopy volume of 1195.99 m3 was recorded in treatment T5-[Water requirement at 100% of EP].Treatment T3-[Water requirement at 50% of EP] significantly performed better in fruit size (fruit length and fruit breadth of 10.00 cm and 8.20 cm, respectively) and also showed maximum fruit volume of 239.75 (cc). On the basis of findings, it may be concluded that frequent and appropriate application of water at the effective root zone of plant plays an important role in growth and yield of mango.
