Field bio-efficacy and phyto-toxicity of vitormone (Azotobacter chroococcum L.) on growth and yield contributing characters in Chilli (Capsicum annum L.)

Chilli (Capsicumm annum L.) is one of the important spice and vegetable crop grown in India and World. Hence, the present trial was conducted during 2014-15 at Zonal Agricultural Research Station, Jhabua (RVSKVV - Gwalior) - 457661 Madhya Pradesh, with a view to assess the bio-efficacy of Vitormone (Azotobactor chroococcum) on chilli hybrid. Vitormone study was undertaken at 0.5, 1.0 and 2.0 ml/L along with 100% NPK (RDF) and 75% N and 100% PK at KVK Jhabua. Results obtained revealed that spraying of Vitormone @ 2.0 ml/L along with recommended dose of fertilizer (RDF) at 35, 55 and 75 days after transplanting significantly increase in plant height (19.77%), number of branches/plant (80.0%), fruit length (81.52%), number of fruits/plant (51.12%) and yield by 43.24% over control and by 4.44% more over RDF. Likewise, spraying of Vitormone @ 2.0 ml/L did not show any phytotoxic effect on chilli crop.
