Influence of different irrigation methods on growth and yield of summer greengram (Vigna radiata L.)

Abstract

A field experiment was conducted at Wetland farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during summer 2022 to study the effect of growth and yield parameters of greengram under different irrigation methods. The field experiment was laid out in randomized complete block design having seven treatments and replicated thrice. The treatment are T1: Check basin method (Line sowing), T2: Check basin method (Broadcasting), T3: Raised bed method (Line sowing), T4: Ridges and furrow method (Line sowing), T5: Drip irrigation system (Line sowing), T6: Drip irrigation system (Broadcasting) and T7: Sprinkler irrigation system (Line sowing).Experimental results showed that significantly higher plant height, number of branches plant-1, number of pods plant-1, pod weight plant-1, number of seeds plant-1, seed yield and haulm yield were recorded in drip irrigation system (Line sowing) in greengram which was on par with sprinkler irrigation system (Line sowing). Drip and sprinkler irrigation systems recorded the higher seed yield (42.1% and 36.1%, respectively) over check basin method (Broadcasting). This study revealed that the drip and sprinkler irrigation methods along with line sowing resulted better growth and yield parameters of summer greengram and enhanced its production.
