Abstract
Use of Natural Farming Inputs is viewed as one of the means to avoid using synthetic and inorganic chemicals in agriculture while also achieving the organic goals and sustainability. Present study was planned to check the impact of natural farming inputs and their microbes in the growth of French bean (Phaseolus vulgaris L.) and onion (Allium cepa L.). A field experiment was conducted to see the effect of different natural farming inputs on growth and yield of onion and French bean. The treatments used were T1- Control, T2- Vermiwash, T3- Beejamruth + Jeevamruth, T4- Amritpani + Jeevamruth, T5- Beejamruth + Vermiwash, T6- Beejamruth + Panchgavya + Amritpani, T7- Beejamruth + Jeevamruth + Panchgavya, T8- Beejamruth + Jeevamruth + Vermiwash, T9- Vermiwash + Panchgavya + Amritpani, T10- Panchgavya. Out of which T3 showed higher plant fresh weight, weight of bulb per plant and importantly higher yield as compared to other treatments and control in onion. Whereas in French bean, T9 showed the higher root length, plant fresh weight, number of pod/plant, length of pod, weight of per pod, diameter of per pod, total yield, and foliar nutrients like total nitrogen, total potassium; total sugar and total protein as compared to other treatments. The microbial activity of natural farming inputs was analyzed, in which the higher number of bacterial, fungal, zinc and potassium solubilizing bacterial population was found in Panchgavya. Higher actinomycetes, nitrogen and phosphorus solubilizing population were present in Jeevamruth. In glasshouse, an experiment was conducted to study the role of microbes present in natural farming inputs in French bean. The treatments used were Panchgavya, Jeevamruth, Amritpani, Beejamruth, Vermiwash and the microbes isolated from each. Panchgavya showed the higher root length, fresh weight, dry weight, length and weight of pod, organic carbon, foliar nitrogen content, foliar phosphorus content, urease activity, acid phosphomonoesterase activity and alkaline Phosphomonoesterase activity as compared to control and other treatments. Compared to all isolated microbes, better results were shown by microbes isolated from Panchgavya. Present study showed that
natural farming inputs can be used as effective natural method to enhance the crop growth and productivity under natural conditions and can be a good replacement for chemical fertilizers.
