Title : Biofortification effect of vermicompost, zinc and iron on yield and quality of hybrid maize (Zea mays L.)

Abstract :

The present study investigated the biofortification effect of vermicompost, zinc and iron on yield (grain and stalk q h-1), protein, starch and amylose content in grain of hybrid maize at harvest. Soil application of Zinc (0.005 t) and Iron (0.01 t) along with 2.5 t vermicompost h-1 gave highest grain yield (47.41 and 49.72 q h-1) and stalk yield (72.07 and 74.29 q h-1) for two consecutive years, while the highest protein content (10.87 and 10.93%), starch content (52.55 and 52.60%), amylose content (19.22 and 19.30%) was recorded with 0.0075 t zinc + 0.015 t iron + 2.5 t vermicompost h-1. Yield (grain and stalk) and quality parameters (Protein, starch and amylose) were significantly increased over control as a result of treatments applied. Superior yield and quality of hybrid maize was achieved with the combined use of zinc and iron along with vermicompost as compared to sole application of zinc, iron and vermicompost.
