TAILIEUCHUNG - Effects of irrigation regime and nitrogen level on yield and yield attributes of summer Maize (Zea mays L.)

Maize (Zea mays L.) is one of the most important cereal crop species and is grown throughout a wide range of climates. In India, maize is the most important food crop after rice and wheat. Since 1950, the area, production and productivity of maize have increased more than , 12 and times from m ha, m t and 547 kg/ ha to current level of m ha, m t and 2414 kg/ha, respectively due to increase in maize demand for diversified uses. Maize could be grown in wide ranges of soils and climate throughout the year. Deficit irrigation scheduling on the other hand is the practice of irrigating crops below the full water requirement. The effects of water stress on crop growth and grain yield will depend on the timing and magnitude of water stress as well as crop type, since different crops have different levels of tolerance to water stress. For many field crops the most critical period of water stress is during the transition from vegetative to reproductive growth or from flowering to fruit setting. Nitrogen fertilizer played important role in improving soil fertility and increase in crop productivity. A study has been conducted during summer season of 2018 at Bagusala Farm ( N latitude and E longitude) of MSSSoA, CUTM, Parlakhemundi, Odisha under typical humid and sub-tropical climatic conditions to know the best irrigation scheduling and optimum nitrogen level for summer maize. The treatment combinations include three irrigation levels (I1, I2 and I3 at , and IW/CPE respectively) and four nitrogen levels (N1, N2, N3 and N4 at 100%, 50%, 25% and 0% organic sources respectively). | Effects of irrigation regime and nitrogen level on yield and yield attributes of summer Maize (Zea mays L.)
