| Abstract: | An experiment upon an agri-silvicultural system involving Willow (Salix alba) tree, Kale (Brassica oleracea var. acephala) and Knol khol (Brassica oleracea var. caularapa) was laid in randomized block designed at farmers’ willow field at Shalimar near Sher-e-Kashmir University of Agricultural
Sciences and Technology of Kashmir, Srinagar India during 2005 and 2006. The main plot was divided into sub-spots with 8 m
× 2 m in size each in which four two-year-old willow (Salix alba) trees were at a spacing of 2 m × 2 m in a sub-spot. The intercrops were maintained at recommended spacing and supplied with
recommended doses of fertilizers. The benefit-cost ratio in willow plantation intercropped with vegetable crops of Kale and
Knol Khol was analyzed and compared with the benefit-cost ratio of sole willow tree forestry. The results showed that every
rupee invested in plantation of agri-silvicultural system generates benefit-cost ratio of 2.78 and 2.79 in case of Willow
intercropping with Kale and Willow with Knol khol, respectively, while as for sole crop of willows benefit-cost ratio was
calculated to be 2.66. These results provided circumstantial evidence in favour of adopting agroforestry involving willow
instead of Sole tree forestry. |
