Abiotic stress impact on moong (Vigna radiata L.) and strategies by earthworm enhance soil condition

Abstract

Moong (Vigna radiata L.) generally known as green gram is one of the most important legume and contain a high composition of proteins, vitamin, mineral and thymine, niacin and ascorbic acid. It has wider adaptability to grow short-duration (65-90 days) and requires low input. High or regular increasing temperature will be detrimental for growth functions of various crop plants and increasing demand of Moong during spring/summer season in major growing region in Northern parts of India. Decrease in Moong quality and yield are influenced by abiotic constraints like high temperature, drought, salinity, metal. Photosynthetic activity is recognized as sensitive to elevated temperature and causes loss of chlorophyll and reduction in carbon fixation and assimilation. Aim of study, the role of abiotic stress impact on the growth of moong and the significant role of earthworm to improve the growth and productivity of moong. In the northern plain, India lies in the Indo-Gangetic plain, moong is grown in the summer/spring season for cropping patterns followed by potato, tomato, wheat etc., these are the major crop in Haryana, Punjab and Uttar Pradesh. In heat stress, an adaptation of physiological and biochemical processes gradually may lead to improvement of heat tolerance in plants. Soil conditions manage by agronomic practices at farm for enhance the productivity and quality. Hence, it is necessary to enhance productivity of food grain legumes by available sustainable source i.e. improve soil condition e.g. salinity, ion-extraction. Earthworms play an important role to promote the growth of mung bean and other crop in a sustainable way. Earthworm and its product (vermicompost and vermiwash) aid to overcome in stress condition and provide nutrition to crop.
