摘要

This study investigated sustainable nutrient management for urban terrace tomato cultivation at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, India. Conducted during the 2024–2025 rainy and winter seasons, the research evaluated four frameworks: Natural Farming (jeevamrut-based), Organic Farming (vermiwash-based), Conventional (synthetic fertilizers), and an absolute control. Parameters included growth, yield, quality, nutrient concentration, and rhizosphere microflora dynamics. Conventional management proved significantly superior for vegetative growth and productivity (5.80 kg m-2). However, for growers transitioning towards sustainable, low-input alternatives, strategic bio-input applications at 20, 40, and 60 days after transplanting (NF2 and OF2) offered scientifically validated options, enhancing rhizosphere microbial densities and yielding fruit lycopene (4.20 to 4.21 mg 100 g-1) statistically comparable to the synthetic system. Winter cultivation produced 56% higher yields (5.95 kg m-2) than the rainy season (3.82 kg m-2) due to favourable thermal windows. While conventional systems optimized primary fruit nutrient concentrations, unfertilized controls and moderate bio-inputs exhibited the highest ascorbic acid levels and maintained superior tissue integrity against post-harvest degradation. Optimal winter microclimates enhanced liquid bio-input efficacy. Ultimately, while conventional inputs elevate immediate tomato crop productivity, targeted three-dose bio-liquid pipelines provide a biologically stable, high-quality alternative for terrace farming, provided local urban supply bottlenecks are logistically resolved.
