Influence of irrigation regimes and organics on the productivity and quality of vegetable cowpea (Vigna unguiculata (L) Walp)

Abstract

A field experiment was conducted at Agricultural College and Research Institute, Killikulam during Rabi season (October 2018 - January 2019) in order to identify a suitable irrigation regime and organic nutrientfor vegetable cowpea (Vigna unguiculata (L) Walp). The experiment was laid out in strip plot design with three replications.There were ten treatment combinations, consistingof two horizontal treatments (irrigation regimes IW: CPE ratio I1-0.4 and I2-0.6) and five vertical treatments (sources of organic. M1-Enriched FYM, M2-Poultry manure, M3-vermicompost, M4-pressmud andM5- inorganic fertilizer). The objectives of the study were to analyze the productivity and quality of vegetable cowpea influenced by irrigation and organic nutrients sources.The results indicated that irrigation at IW: CPE ratio 0.6 showed significantly higher growth and yield parameters which was associated with sources of organic. Enriched FYM gave significantly better results in green pod yield, quality parameters compared to other organic manure.The combination of the treatment (I2M1) both irrigation regimes and organic (IW: CPE ratio 0.6 and enriched FYM) produced the highest yield in vegetable cowpea during Rabi 2018-19.
