Effect of Vermicompost and P Enriched Biocompost on Soil Properties under French bean Crop

Abstract

French bean (Phaseolus vulgaris L.), a member of family fabaceae, is one of the most ancient and popular warm season vegetable crop grown worldwide for its green pods. It is an important source of protein, calcium, iron and vitamins in human diet. The crop is known by various names as French bean, common bean, snap bean, kidney bean and navy bean. In India, it is commercially cultivated in Himachal Pradesh, Jammu and Kashmir, hills of Uttrakhand, North-Eastern states and peninsular India, covering an area of about 1,50,000 ha with annual production of 4,20,000 tonnes and ranks 4 th in green bean production in the world. Its cultivation in Northern Indian plains is rather restricted in account of limited period of favorable weather conditions. It occupies an area of 3,197 ha with annual production of 33,112 metric tonnes in Himachal Pradesh. Biocompost and vermicompost supplement the nutrient requirements of crops. Concerning the economic sustainability, the low cost of compost is useful to farmer as well to human society. Vermicompost is reported to be rich in nutrient elements (Jambhekar, 1992) and biocompost also contains high amount of nutrients than ordinary compost or FYM.

Organic inputs with reduced chemical fertilizers improve yield, antioxidant components, and defense mechanisms in Tomato (var. Pusa Sheetal)

“…The study found that post-harvest soil parameters were significantly improved by applying a combination of FYM, VC, and reduced NPK fertilization, yielding more significant results than conventional fertilizers alone (Figure 4). Similar findings have been reported by Alah et al [37] and Paul et al [38]. Vermicompost offers sustainable, eco-friendly solutions for improving sustainable crop production.…”

Morphological and Physiological Response of Tomato to Sole and Combined Application of Vermicompost and Chemical Fertilizers

“…According to the literature, more vermicompost is associated with higher soil organic matter levels [78]. It has also been observed that the soil's content of organic carbon (C) increases with increasing doses of vermicompost, followed by organic waste [79]. It is reported that vermicompost has a valuable source of readily accessible nutrients.…”
