A field survey was carried out in Nagal Hatnala village of Dehradun to evaluate the growth, biomass and productivity of Brassica campestris in an agroforestry system in Doon valley. Traditional agri-horti-silviculture system comprised of where fruit, fuel and fodder trees were present along with intercrops at the boundaries. The trees present were Toona ciliata, Mangifera indica, Bombax ceiba, Eucalyptus tereticornis, and Dalbergia sissoo. Agroforestry is a common practice in the Doon valley. Farmers are inclined towards retention of fruit based tree on their agricultural fields for addition monitory gains from the fruits and therefore agri-horticultural practices is the priority of high land holding farmers as the climatic and geographical situation also permit such practices. The study concludes that there was a significant reduction of agricultural productivity (grain, straw, and biological yield) under trees as compared to sole agricultural systems Sole crop showed maximum grain yield (26.45 Mg/ha) and straw yield (18.97 Mg/ha). Both grain and straw yield were 3.0 times and 2.94 times more in sole crop in comparison to crop growing under trees. Biomass of different plant components was in the order of shoot>silique>leaf>root i.e., 25.30 Mg/ha, 10.56 Mg/ha, 8.83 Mg/ha and 7.07 Mg/ha respectively. Data on yield attributes and biomass showed statistically significant variation between crop growing as sole and under trees.
