Assessment Effect of Vermicompost on Quantitative and Qualitative Characteristics of Mung Bean (<i>Vigna radiata</i> L.) Under Different Irrigation Regime

Abstract

<strong>BACKGROUND</strong>: Vermicompost in sustainable agriculture is very useful for improving soil porosity and thereby providing more nutrients to crop.<br /> <strong>OBJECTIVES</strong>: Current research was conducted to evaluate effect of biofertilizer (vermicompost) under different level of irrigation on crop production and protein yield.<br /> <strong>METHODS</strong>: This study was carried out via split plot experiment based on randomized complete blocks design with four replications along 2018 year. The main factor included different interval of irrigation (I₁= 70mm, I₂= 90mm, I₃= 110mm and I₄= 130mm evaporation of Pan) and four level of vermicompost (V₁= control, V₂= 4 t.ha^-1 and V₃= 8 t.ha^-1).<br /> <strong>RESULT</strong>: According result of analysis of variance effect of different interval of irrigation and vermicompost on all measured traits was significant, also interaction effect of treatments on seed yield, number of pod per m² and 100-seed weight was significant. Result of mean comparison of different interval of irrigation revealed maximum amount of number of seed per pod (7.87) and protein yield (44.1 gr.m^-2) was for 70 (mm) evaporation of pan treatment but highest amount of protein percentage (24.43%) belonged to 130 (mm) evaporation of pan. Also the maximum amount of mentioned traits was for use 8 t.ha^-1 vermocompost and minimum of those were for control. Mean comparison result of interaction effect of treatments revealed the highest amount of seed yield (250.14 gr.m^-2), number of pod per m² (304) and 100-seed weight (11.01 gr) were obtain for 70 (mm) evaporation of pan with use 8 t.ha^-1 vermocompost and lowest ones were for 130 (mm) evaporation of pan with nonuse of vermocompost.<br /> <strong>CONCLUSION</strong>: The present study revealed that the use of vermicompost is useful for improve growth of mung bean under water stress situation. In order to achieve maxi-mum quantitative and qualitative yield the treatment of irrigation intervals with 90 (mm) evaporation of pan (it doesn't had significant difference with 70mm evaporation of pan) with application 8 t.ha^-1 vermicompost under water stress condition can be advised to the producers.
