Abstract

A study on Effect of long term fertilization and manuring on soil quality and nutritional quality of maize (Zea mays L.) under finger millet-maize cropping system was carried out in LTFE plots which has been in progress since 1986 at UAS, GKVK, Bengaluru. Eleven treatments were laid in randomized block design with three replications. The hybrid maize was grown in LTFE plots during Rabi 2021-2022 (35th crop cycle) and qualities of grain were assessed. Application of 100 per cent NPK+ FYM+ lime recorded significantly higher grain quality viz., geometric mean diameter (7.63 mm), bulk density (791 kg m-3), 1000 grain mass (444.10 g), colour (L*72.91, a*4.68, b*27.48), crude protein (10.35%), ash (1.73%), moisture (8.19%) and crude fibre (1.85%). Inorganic fertilization alone, 100% N, 100% NP and control treatments recorded poor quality grain of maize. The conjoint use of organic manures along with chemical fertilizers in balanced form is essential to maintain good soil quality and for quality maize production.
