Abstract

The most pressing concern in today’s agriculture is the decline in soil health, due to the excessive use of inorganic fertilizers and poor organic matter management. The sustainability of vegetable production like knolkhol is compromised due to unsustainable practices reducing productivity and loss of soil biodiversity. Addressing these issues food waste compost can offer a sustainable solution by providing nutrient-rich soil amendment to farmers and environmentally responsible waste disposal. Thus, present investigation was conducted during the rabi 2024-25 at the Vegetable Research and Demonstration Farm, MSSSoA, CUTM, Odisha, India to evaluate the effect of different dosage of food waste compost on growth and yield of knolkhol. The experiment was conducted in a randomized block design having eight treatments of varying levels of food waste compost were replicated thrice. The eight treatments chosen for the study were: 1, 2, 3, 4, 5, 6 t/ha food waste compost, recommended dose of fertilizer along with control. The highest nitrogen (48.37 kg/ha) and phosphorous (9.54 kg/ha) uptake observed in treatment with 3 t/ha food waste compost but decreased at higher levels, however, a gradual increase in potassium uptake was recorded with increasing level of food waste compost and maximum (53 kg/ha) with 6 t/ha food waste compost application. The maximum knob yield (15.70 t/ha) was obtained with 3 t/ha which was similar to the treatment receiving recommended dose of fertilizer (15.30 t/ha) but found significantly higher over other treatments. However, the yields showed decreased trend at higher rate of food waste compost application beyond 3 t/ha. Findings of the present study suggest that the application of 3 t/ha food waste compost in place of recommended dose of fertilizer will be a promising strategy to grow the knolkhol organically without decreasing productivity in southern Odisha.
