Crop-specific enriched vermicompost and its role in sustainable oilseed crop production

Organic farming has gained increasing attention in recent years due to growing concerns about soil health, environmental sustainability and consumer preference for safe and chemical-free food. Among various organic inputs, enriched vermicompost (EVC) has emerged as a promising alternative to chemical fertilisers, owing to its ability to improve soil fertility and crop productivity. The present study was undertaken to assess the effect of crop-specific enriched vermicompost on the growth and yield attributes of mustard (Brassica juncea L.) and sesame (Sesamum indicum L.). The experiment comprised three nutrient management treatments, viz., T1, T2 and T3. Growth and yield parameters such as plant height, number of branches per plant, leaf area index, number of pods (capsules) per plant, protein content, oil content, root length density at harvest, shoot biomass (fresh and dry weight), test weight, seed yield, straw yield, biological yield and harvest index were recorded. The results revealed that all treatments performed statistically at par with respect to growth and yield attributes of both mustard and sesame. These findings indicate that crop-specific enriched vermicompost prepared using organic wastes, minerals and biofertilizers can potentially substitute chemical fertilisers without significant yield penalties. Thus, the use of enriched vermicompost in oilseed crops not only ensures sustainable yield but also contributes to soil health management and reduced dependency on synthetic inputs.
