The center resorted to undertake this research trial as such initiatives are felt mandatory if we are to achieve our nation's steadfast mission of going organic by the year 2020. It is also geared towards finding means of replacing our current trend of agricultural system, wherein we are using excessive chemical fertilizers in nourishing our plants while we are least bothered about the health of our soils. While many dwelling in the farming community have minimal or no knowledge on the beneficial soil microbes, it is also to be emphasized that farmers need to be educated on this aspect of maintaining soil health and the crucial role such microbes can play in agriculture. The need to stress on the maintenance of soil health which is a gateway to sustainable farming is also to be prioritized.

Ø To address the increasing problems associated with the use of synthetic agro-chemicals in agriculture through the use of bio-fertilizers.
Ø To find means of practicing sustainable agriculture by providing an ecological environment where all the microbial community could live in harmony wherein they can balance each other in their quest for food and space.
3. Materials & Methodology
The RCBD experimental design was used to carry out the trial. A total of 7 treatments including control and 3 replications were designed. The trial encompassed a total area of 105 sq. m. with 21 plots of 5 sq. m. each. The seedlings were spaced at 30*45 cm, amounting to a total plant strength of 693.
The 7 treatments namely; FYM, vermi-compost, vermi-wash, liquid manure form biodigester tank, compost tea, heap compost and control were used.
|Treatments 1-3: FYM; Vermi-compost;Vermi-wash.|
The solid bio-fertilizers were applied around the root zone while the liquid formulations were poured around the root zone of the crop on fortnightly interval except for FYM which was stopped after its second application. In total, there were 6 applications in the entire crop period.
4. Result & Discussion
For yield analysis against different treatments, 10 plants per plot were randomly selected and the curd weight recorded. The average curd weight are as depicted in table 1.
Table 1: : Average curd weight(g) of 10 randomly selected plants/plot
Average curd weight(g)
From the data, the average curd weight of the plots with same treatment were derived, & the yield per acre and the comparative yield advantage of the other treatments over the control plot were also worked out accordingly as illustrated in table 2.

Though the data didn't show much statistical significance between the treatments, it does have some difference in the physical weight of the curds. Accordingly, the comparative yield advantage of the different treatments over control can be seen.
