Organic farming is one of the best alternate crop production systems to safe guard human health and other life in agricultural ecosystem from toxic chemicals used in agriculture. Cluster bean is leguminous industrial crop, with huge demand for various sectors like food consumer markets, pharmaceuticals, medicine etc. Indiscriminate use of chemical inputs in cluster bean cultivation affects human health system and environment. So, the research on influence of different organic nutrient sources compared to conventional recommended dose of fertilizers (RDF) on dry-matter partitioning and physiological parameters on vegetable cluster bean was explored. The experiment was carried out using randomized complete block design (RCBD) with twelve treatments and three replications at irrigated condition ta Agricultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore between June to September, 2018. The dry weight of root, stem, leaf and total plant dry weight, LAI, CGR, AGR and RGR of cluster bean were measured and had shown significant difference with application of recommended dose of fertilizer (50:50:25 – NPK) along with a foliar spray application of TNAU pulse wonder (T11). However, it was statistically on par with organic farmers’ practice (T1) and FYM @ 25 t/hain addition to foliar spray of 3% Panchagavya (T2). Considering the need for chemical free environment at food production sites, the farmer’s practice of applying FYM @ 10 t/ha + Jeevamruth @ 500 l/ha through irrigation + foliar spray application of Panchagavya @ 3% is found to beneficial for vegetable clusterbean growth and yield.

Along with food security, it is necessary to consider the safety of environment, human health and in agriculture and food production system. So, it is concluded that the farmer’s practice – basal application of farm yard manure (FYM) @ 10 tonnes per hectare, along with Jeevamruth @ 500 litres per hectare application along with irrigation water and foliar spray application of Panchagavya @ 3 per cent is found to provide better growth rate and better partitioning of photosynthates to sink for higher yields in vegetable clusterbean.
