Abstract : A survey was conducted during the rabi [winter] season of 1993-94 to study the fruit tree based agroforestry systems (AFS) existing on farmers' fields in the Sahaspur-Vikasnagar blocks of the Doon Valley, Uttar Pradesh. Based on age groups, the AFS were classified into various categories. Among the various fruit types, the mango [Mangifera indica] based AFS was most popular (57.8%) followed by litchi [Litchi chinensis] (15.6%), guava [Psidium guajava] (11.2%), kinnow [mandarin] (7.8%), peach [Prunus persica] (4.4%), lemon [Citrus limon] and olive [Olea europaea] (1.1%). Wheat was the main ground storey crop among the fruit types. Mango with wheat was the dominant system prevailing in the area. In case of mango and litchi up to 14 yr old with 48.6 and 43.5% canopy cover, the yield reduction of the wheat crop was 42.5 and 39.8%, respectively, and thereafter the reduction in yield was more than 50% in both cases. The yield reduction was less in the cases of guava, kinnow and peach, even at fully grown stages (15-21 yr). The farmers also used some of the tree species as multipurpose boundary plantations.
