Abstract

Use of chemical fertilizer is responsible for the loss of soil texture, soil fertility and also food nutrition. But, farmers couldn't cultivate without chemical fertilizers and pesticides because of the presence of huge pests in the environment. In this point, only pesticide tolerant nitrogen fixers are very much essential to take the challenges to return the soil texture and fertility. In relation to the current context, one Azotobacter sp., shown to resist the maximum percent of three chemical pesticides, CP α, CP β, CP γ, one bactericide and one bio-pesticide, Neem seed oil in presence of fertilizers, UREA, DAP, NPK (10:26:26), MOP, SSP, NPK (15:15:15) which ultimately reflected in crop production by supplying fix nitrogen to the soil. A critical work has been done to find out a pesticide resistance strain, Azotobacter sp., which ultimately will solve a long waited cultivator’s problem for crop improvement.

Conclusion

Farmers have been using huge amounts of chemical fertilizers, pesticides and bactericides in vegetable fields for more yields. It disrupts the chemical balance of natural soil. Thus, a reduction of the use of aforesaid chemicals is urgently needed. The present study specifies the use of Azotobacter along with a minimum amount of chemical fertilizers, chemical pesticides, and chemical bactericides in the field (vegetable) for crop production. Neem seed oil would be a good alternative to chemical pesticides and bactericides. Azotobacter could tolerate up to 0.4% of chemical pesticides and bactericides, 0.9% UREA, 1.1% DAP, 0.9% NPK (10:26:26) and 0.7% of MOP, NPK (15:15:15), SSP and 1.5% of bio-pesticide. The Azotobacter could be used as a biofertilizer for better crop production and minimum environmental disturbance.
