Effect of different iron and zinc application on growth, yield and quality parameters of mungbean (Vigna radiata L.).

Abstract

An investigation was conducted using 12 mungbean varieties in kharif 2011-12 to investigate the effct of different levels of iron and zinc (appled through chemical chelates/ fertilizers) under uniform levels of NPK on growth, quality traits (protein, iron and zinc content) and yield performance of diverse munbean, cultivars under irrigated conditions at CCS HAU research farm, Hisar and regional Research Station , Uchani , Karnal. This experiment depicted notable response in growth, quality (protein, Fe and Zn content) and yield. Highest seed yield (17.27 g/plant) was recorded in T7 (RDF+50 kg/ha fe So4+ 0.5% FeSo4 foliar spray before flowering). The interactive effect of mungbean varieties and treat,ents was found significant in seed protein, iron and zinc contents. Maximum contents of protein (27.8 9%) and iron (9.90 mg/ 100gm of seed) were observed with application of T5 (RDF+0.5% FeSO4 foliar spray before flowering ). Due to application of treatment T4 (RDF+ 0.5% ZnSO4 foliar spray before flowering), zinc content was higher (2.30 mg/100g of seed) in mungbean It is strongly recommended doses of fertilizer in mungbean for enchnacement of production , quality and upliftemnt of their socio-economic status.
