FIELD TRIALS AND EXPERIMENTS
Conventional agriculture plays a significant role in meeting the food demands of a growing human population, which has also led to an increasing dependence on chemical Fertilizers and pesticides. Chemical fertilizers are industrially manipulated, substances composed of known quantities of nitrogen, phosphorus and potassium, and their exploitation causes air and ground water pollution by eutrophication of water bodies. In this regard, recent efforts have been channelized more towards the production of ‘nutrient rich high quality food’ in sustainable comportment to ensure bio-safety. The innovative view of farm production attracts the growing demand of biological based organic fertilizers exclusive of alternative to agro-chemicals. In agriculture, encourage alternate means of soil fertilization relies on organic inputs to improve nutrient supply and conserve the field management. Organic farming is one of such strategies that not only ensures food safety but also adds to the biodiversity of soil. The additional advantages of biofertilizers include longer shelf life causing no adverse effects to ecosystem
In order to improve the productivity of different crops in the State, various trials have been conducted in Experimental Farms and Farmers’ Field on the effects of bio-inoculants such as Trichoderma and Phosphate solubilising bacteria and different organic composts on productivity of different crops like potato, pea, french bean, ginger, turmeric, maize, etc. Trials have been conducted in over 40 farmer’s fields of 27 villages across the State.
The result on crops which were harvested is encouraging in term of improved productivity and soil health. More of such field trials need to be conducted with scientific documentation before finalizing recommendation, etc.
