Effect on Yield and Yield Component of Maize (Zea mays L.) Due to Planting Patterns and Different Irrigation Levels

To study the effect of two planting patterns viz. 60 cm apart single rows and 30/90 cm apart double row strips (30 cm from row to row and 90 cm from strip to strip) and different irrigation levels viz. 0, 3, 4, 5 and 6 irrigations on growth and yield of maize, a field trial was carried. The growth and yield of maize were not influenced by planting patterns but number of plants per plot at harvest, number of grains per cob, 1000 grain weight, biological yield, grain yield and harvest index were significantly affected by different irrigation levels. When planting spacing was kept at 30/90 cm apart; double row strips (30 cm from row to row and 90 cm from row to row) and 6 irrigations, maximum grain yield (7.37 t ha⁻¹) was produced.
