Effect of bio-composts on soil fertility status and productivity of organic farm: An approach to promote sustainable agriculture
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 4
Abstract
The findings of this research provide information on various approaches to manage and maintain soil fertility for organic crop production through composting. The initial recorded data pertaining to various conventional farming practices showed very low soil fertility status, low productivity before the initiation of organic farming. In the year prior to 2006 pH was low (4.10) and it increased to 5.40 by 2006-07. Organic carbon percentage increased to 1.35 in 2006-07 and the value of phosphorus was very low in the previous year but increased in the year 2006-07 (6.00 Kg/ha) while Potassium value increased in the year 2006-07 (395.00 Kg/ha). Input use pattern of various composts was also evaluated and it was observed that higher rates of FYM was used in case of maize-wheat+gram (614.31q/ha) in 2006-07 while higher rates of vermicompost was used in case of soybean-pea system i.e 111.11 q/ha for the year 2006-07. It was found that in the year 2006-07, among the cereals, yield of wheat was the highest (15.56 q/ha), among pulses soybean dominated (13.04 q/ha). The yield of potato (74.88 q/ha) was the highest among vegetable crops. For the year 2007-08, the yield of wheat+ lentil was the highest (10.86 q/ha). Among the pulses again yield of soybean was the highest (6.14 q/ha) and potato showed the highest yield among vegetables (73.88 q/ha). It showed that the application of compost had direct effect on productivity as the application of compost in the year 2007-08 decreased the productivity decreased subsequently as compared to initial year i.e 2006-07.
