Abstract

Effect of balance and imbalanced fertilization on soil physical Properties, nutrient uptake, growth and yield of rice in Chhattisgarh was studied under long-term fertilizer experiment during kharif 2019-20 at research farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The experiment comprised of different levels or doses of NPK fertilizers alone and in combination with zinc sulphate, farmyard manure (FYM), blue green algae (BGA) and green manuring (GM) was laid out in randomized block design with four replications and ten treatments viz. Control, 50% NPK, 100% NPK, 150% NPK, 100% NPK+ZnSO4@ 10kgha-1,100% NP, 100% N, 100% NPK + FYM @5t ha-1, 50% NPK+BGA@ 10kg ha-1 and 50% NPK + GM @40kg ha-1. The results showed that the physical properties like total porosity, gravimetric and volumetric moisture content, hydraulic conductivity, infiltration rate, water stable aggregates and mean weight diameter of the soil were increased, while the bulk density was reduced significantly with the 100% NPK FYM treatment over all other treatments. However, the use of imbalanced (100% N and 100% NP) fertilizer, super optimal (150% NPK) and sub optimal (50% NPK) rate of inorganic fertilizer as compared to the unfertilized control showed significant effect on the physical properties of soil. Integrated nutrient management practice including FYM and recommended dose of NPK showed as best treatment with respect to growth and yield parameters like plant height, no. of tillers and no. of grains as compare to other treatments. The grain (5065 kg ha-1) and straw (7075 kg ha-1) yield of rice was registered higher in 150% NPK treatment followed by 100% NPK FYM treatment (4855 kg ha-1 and 6565 kg ha-1) and lowest in control treatment (2350 kg ha-1 and 2680 kg ha-1).

Keywords: Total porosity, gravimetric and volumetric moisture content, hydraulic conductivity, infiltration rate, water stable aggregates and mean weight diameter
