Abstract

Conventional organic garden pea cultivation suffers from lower fruit yield due to the use of traditional nutrient sources like farmyard manure. Selection of proper nutrient management practices can enhance crop growth, yield and as well as soil health. The residual nutrients after proper nutrient management practices can be better utilized by cultivating succeeding crop in the same field. A field experiment was conducted during 2020-21 and 2021-22 at the UBKV Instructional farm, Pundibari, Coochbehar, West Bengal, India to find out the effect of organic amendments of garden pea cultivation and its residual effect on succeeding Amaranth crop growth and soil fertility status. The garden pea crop was grown in split plot design with three replications by combining four main plot factors and four sub plot factors. Succeeding leafy vegetable crop Amaranth was raised on the same plots of garden pea field. The findings of this study suggested that organic manure application on garden pea crop significantly influence the Amaranth growth and soil quality over the foliar spray. The organic amendments i.e., biofertilizer enriched farmyard manure @ 20 t/ha recorded the highest individual plant weight (6.68 g), fresh plant yield/plot (2.20 kg), fresh plant yield/ha (3.88 ton) and plant biomass (0.78 t/ha) of Amaranth crop. The same organic amendments also recorded the highest residual nitrogen (222.36 kg/ha), phosphorous (18.62 kg/ha) and potassium (99.85 kg/ha) content in the soil after harvesting of Amaranth crop. The experimental findings demonstrated that Azophos biofertilizer enriched farmyard manure may be adopted for organic garden pea cultivation to achieve higher green leaf yield and sustainable soil health in garden pea- Amaranth cropping system.

Keywords

Residual effect, garden pea-Amaranth cropping system, organic, soil fertility, biofertilizers enriched manure.

Conclusion

The present study demonstrated that adoption of Azophos biofertilizer enriched FYM as a source of organic manure for organic garden pea cultivation should be practiced for superior growth, yield of Amaranth crop and soil quality. The practice will help long term sustainability of the soil.
