Abstract
Agroforestry is a land use system where woody perennials are cultivated on the same land management units along with annual/biennial agricultural crops and livestock components. To study the yield of Paddy under the bund plantation of Acacia auriculiformis&Eucalyptus tereticornis, B-C ratio in the agri-silviculture system as well as in the sole crop and growth increments of the tree components in the bund plantation an experiment was conducted in two different fields in Kendrapada District (Odisha) during the year 2020-21 in Kharif season (Oct-Dec). Observations were recorded for severalgrowth and yield parameters such as Height measurement of paddy plants in 30-day interval till the harvest of crop 150 DAP, No. of Tillers /Plant at harvest, Panicle length of Paddy at harvest, Number of grains per panicle at harvest, Seed weight of 100 grains at harvest, Grain yield (q/ha), Straw yield (q/ha), Biological Yield, Harvest index (%), Height of trees present in the field bunds, Diameter at Breast Height (D.B.H.), Girth at Breast Height (G.B.H.) for both the tree and crop components in a 30 days interval. The same observation also recorded under sole cropped field of the paddy varieties Pooja and Kalachampa. The observed data was then statically analyzed using T-test. After analyzing and computing the data of this experiment results showed that If we consider only growth parameters and economic yield of paddy, bund plantation of trees has an adverse effect on paddy up to 5% of low yield. But when we calculated the B-C ratio, B-C ratio of the sole crop was significantly lower than the B:C ratio of crop under bund plantation of A.auriculiformisand E.teretocornis. In experimental site – 1, the B-C ratio of sole crop was 2.04 whereas the B- C ratio of crop with the bund plantation of A.auriculiformiswas 3.00. In experimental site
- 2, the B-C ratio of sole crop was 2.22 whereas the B-C ratio of crop with the bund plantation of E.teretocorniswas 2.55. This is due to wood component income after harvest of mature tree crop farmers get money in 12 year. The calculation of amount obtained in 12 year equally divided by yearly basis. BC ratio we may conclude the results that there is more economic benefit when we plant trees on field bund along with the crops despite of a little reduction of the yield of rice compared to the sole crop. Thus agroforestry system is economically beneficial in the long run as compared to a sole crop. After this experiment we can suggest the farmers in Kendrapada to go with bund plantation of trees rather than sole cropping of Paddy. As bund plantation of trees improve the soil fertility with litter decomposition and addition of nitrogen through nitrogen fixing trees. The bund plantation of agroforestry trees are beneficial for to enhance the income as well sustainable agriculture maintain soil fertility both this comes under eco-friendly agriculture system.
