Abstract
An experiment was conducted to study the physiological effects of a bioinoculant ( NovoBac ) on growth and yield of vegetable cowpea var.VBN 2. The morpho-physiological, biochemical, nutrio-physiological and yield parameters of cowpea were significantly influenced by the biostimulant. NovoBac seed treatment at 2g/kg + soil drenching at 500g/ha on 15 days after sowing (DAS) favourably influenced the plant height. A significant increase in the number of leaves and root length was recorded by NovoBac seed treatment at 2g/kg + soil drenching at 500g/ha on 15 DAS. The data on crop growth analysis also revealed the significant influence of NovoBac treatments. The physiological and biochemical constituents such as soluble protein content and the IAA oxidase enzymes activity were greatly enhanced. The yield and yield components such as days to 50 percent flowering, number of flowers per plant, number of pods per plant, fertility co-efficient, number of seeds per pod, pod weight per plant, pod length and hundred seed weight were significantly influenced by the biostimulant ( NovoBac ). The quality of seeds was also improved by this treatment through enhanced protein content. A close scrutiny of the data on correlation studies showed that pod yield was significant and positively correlated with the traits such as plant height, root length, leaf area index, leaf area duration, crop growth rate, dry matter accumulation, chlorophyll, soluble protein, IAA oxidase, uptake of NPK, bacterial population and soil dehydrogenase activity. It is concluded from the present study that NovoBac seed treatment at 2g/kg + soil drenching at 500g/ha on15DAS resulted in higher vegetable pod yield (6.22 t ha-1). However, considering the B:C ratio, NovoBac seed treatment at 2g/kg + soil drenching at 250g/ha on 15 DAS) was found to record higher ratio of 1: 2.2
