Abstract

In organic farming system the use of biofertilizer plays a significant role due to its sustainability to improve the soil health, microbial activity, soil fertility and productivity of crops. The farmer of North East India mostly uses imbalance fertilizer in their crop field either by organic or by inorganic means. Moreover, the Hilly part of this region mostly use organic matter in imbalance dose in their crop field. So, the productivity of vegetable crop is very less compare to other part of India. This study on ‘Effect of Biofertilizer based organic nutrient management in soil health and productivity enhancement of pea (Pisum sativum) in North East India’ evaluates the impact of organic matters along with biofertilizers on properties of soil, availability of nutrients, growth and yield parameter of pea for contributing a better understanding of sustainable agricultural practices in the region as well as for profit maximization in vegetable cultivation. The study was done through field study, analysis of different parameters of growth and yield of pea, soil testing and through statistical evaluations. For the present study a FLD programme was done in the Farmers Field of Ri-Bhoi District to demonstrate a Technology with comparison to local Farmer practices. The Treatments comprises were T1: FYM @ 5 t/ha + @400 kg/ha+ vermicompost @ 5 t/ha + Rhizobium 10kg/ha + PSB10kg/ha + Organic Mulch and T2: Farmers Practice (FYM 5t/ha). The pea variety taken was Aman which was covered in 1 ha. of Land in five villages namely Thadnongiew, Umeit, Kyrdem, Nonglakhiet and Nongpoh. The results of the FLD revels that the T1 gives higher yield of 28.6 q/ha with B:C ratio of 2.69 as compare to Farmers practice i.e., 16.8 q/ ha with B: C ratio of 1.82. The organic carbon, available nitrogen, available phosphorus and available potassium were significantly higher in the treated plot as compare to Farmers practice. The results of the FLD revels the feasibility of adoption of Biofertilizer based organic nutrient management practices in North East India as a sustainable approach for increase the productivity of crop as well as for enhancement of soil health for the development of socio-economic status of this region.

Conclusion

The use of beneficial microorganism by biofertilizers, generate and release the nutrients which increases the soil fertility required for crop growth and development. Moreover, it improves the soil structure and promote nutrient cycling and helps for organic matter breakdown. The present demonstration clearly stated that the biofertilizer based organic nutrient management can significantly increase the Pea crop yield and nutrient availability of the soil for plant uptake. So, the technology can be successfully used for promoting organic farming in North East Hilly region of India as a sustainable approach for profit maximization and for economic upliftment of the region. Further researches are required to examine the long-term effects of biofertilizer application on soil health and crop productivity in different locations of North Eastern region. The large-scale adoption of biofertilizer-based organic nutrient management practices will be possible through large scale dissemination of the demonstrated Technology as well as by introduction of new technology to nearby areas for sustainable agriculture for achieving a productive and resilient agricultural system.
