Response of Seed yield, Its Components and Chlorophyll Content of Corn to Integrated Effect of Nitrogen Fertilizer and Vermicompost under Different Irrigation Round

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Improve saving water in irrigated agriculture and thereby improving water use efficiency is of paramount importance in water-scarce regions. OBJECTIVES: This study was conducted to assessment effect of different levels of irrigation regime, nitrogen fertilizer and vermicompost and on seed yield, its components and chlorophyll traits of corn. METHODS: This research was carried out to via split plot experiment based on randomized complete blocks design with three replications along 2015 year. The main factor included three level of irrigation regime (Ir1: 60mm evaporation Pan Class A, Ir1: 90mm evaporation Pan Class A, Ir1: 120mm evaporation Pan Class A) and sub factor consisted three level of fertilizer (N1: 100% Urea fertilizer, N2: 50% urea fertilizer + 50% vermicompost, N3: 100% vermicompost). RESULT: Result of analysis of variance indicated effect of irrigation regime and nutrition on all studied traits (instead harvest index) was significant, but interaction effect of treatments was not significant. Mean comparison result of different level of irrigation regime revealed that maximum amount of studied traits was noted for Ir1 and minimum of those belonged to Ir3 treatment. Also as for Duncan classification made with respect to different level of nutrition maximum and minimum amount of studied traits belonged to N2 and N1 treatment. CONCLUSION: Finally according result of current research Ir1 treatment (60mm evaporation Pan Class A) with apply N2 treatment (50% urea fertilizer + 50% vermicompost) had the highest amount of studied traits and it can be advice to producers in studied region.
