Abstract

Intensive cropping systems with fertilizer responsive crops that rely on high input of inorganic fertilizers often lead to nonsustainability in production and also pose a serious threat to soil health. Application of organic sources of nutrients with no or very little use of fossil fuel-based inorganic fertilizers is rapidly gaining favor. However, considering economics and also physiological potential of varieties, entire dependence on organic sources of nutrients may not be adequate to attain the most productivity. Integrated nutrient management with both organic and inorganic fertilizers was investigated. A field trial was conducted with different fertilizer combinations of organic substrates (cow manure, spent mushroom substrates (SMS) and vermicomposts) and phosphorus fertilization (0, 75, 100 and 125 kg ha) to study their effects on seed number, seed phosphorus and zinc content, oil yield and oil quality in medicinal medicinal pumpkin seed (Cucurbita pepo var. styraca). For lonely application of organic substrates and phosphorus concentrations; vermicomposts and 125 P (kg.ha) treatments had the highest seed number, oil percentage with high value of oleic acid in medicinal medicinal pumpkin seeds. Results from the experiment revealed that among the sixteen treatments compared, the combination of vermicomposts and all levels of phosphorus applications had the maximum of seed number with high oil percentage and qualities. Perhaps in some combine vermicomposts and phosphorus fertilizer applications, linoleic decreased but because of effective role of these combinations on seed number and oil percentage, can help to increase the main important fatty acids.
