ABSTRACT

Mungbean (Vigna radiata L.) is an imperative legume crop in Asia. Iron (Fe) deficiency is a yield-limiting factor for a variety of field crops across the world.

To increase Fe concentration in edible portions of food crops foliar application of Fe- containing solutions might be sustainable and economical strategy; however little information is available in the literature. So the present work was conducted to evaluate the effect of foliar application of iron sulfate (FeSO4) on growth yield and quality of mungbean. The experiment was consisted of foliar applications of 0.5% 1% and 1.5% solutions of FeSO4 both at branching and flowering stages. The results revealed that various FeSO4 treatments increased growth and yield components like plant height number of pod bearing branches per plant number of pods per plant number of seeds per pod 1000-grain weight and seed yield. Moreover application of FeSO4 also improved the quality of mungbean by increasing protein and iron contents in grains.

Application of 1.5% foliar FeSO4 both at branching and flowering stages gave higher number of pods per plant (44.64%) number of seeds per pod (45.31%) 1000-grain weight (18.97%) and grain yield (38.66%) and also improved the quality of grains by increasing protein contents (6.60%) and iron contents (46.39%) in grains as compared to control. Thus we conclude that application of FeSO4 improves the growth yield and iron contents in different parts of mungbean.

INTRODUCTION

Pulses are vital food crops and offer a cheap source of protein. In Asia mungbean (Vigna radiata L.) is an important pulse crop ranked as the second most drought resistant crop after soybean. It has more protein contents and better digestibility than any other pulse crop (Tabasum et al. 2010). It can be grown under drought stress conditions where the short time is available for growth. It grows well under both irrigated as well as rain fed conditions. Salt affected soils are fit for its production while it cannot grow well in waterlogged condition (Yadave et al. 1998). Mungbean grains contain 51% carbohydrates 26% protein 10% moisture and 3% vitamins. The residues of mungbean are also used as feed for animals and enhance the soil fertility as well (Asaduzzaman 2008). A balanced fertilization program with macro- and micro-nutrients in plant nutrition is very important in the production of

high yield with high quality products (Sawan et al. 2001). Micronutrients such as zinc (Zn) selenium (Se) and iron (Fe) play an important role in human growth development and maintenance of the immune system (Shenkin 2006). Iron ( Fe) is one of the most important micronutrients and approximately 2 billion people suffer from Fe deficiency worldwide which has often been claimed to be the predominant cause of anemia (Welch and Graham 1999). It comprises approximately 5% of the earth's crust and is the fourth most abundant element in the lithosphere (Tisadale et al. 1993). Fe is an essential nutrient element for plant growth and development and is involved in chlorophyll...
