Growth performance of wheat varieties under different pruning intensities of Dalbargia sissoo based Agri-silviculture system

Abstract

A field experiment was carried out at Dusty Acre Research Farm, Department of Forestry, JNKVV, Jabalpur to assess the growth performance of wheat varieties in 13 year old Dalbergia sissoo plantation. Maximum grain yield of wheat was recorded when grown under open condition (27.20 q ha-1). Among different pruning intensities, significantly maximum grain yield was recorded under 75% pruning (24.4 q ha-1) which inturn was significantly superior to 50% pruning (21.27 q ha-1) and 25% pruning (19.47 q ha-1). No pruning recorded significantly lowest grain yield (17.74 q ha-1). The percent reduction in grain yield under no pruning 25%, 50% and 75%. Pruning as compared to open condition was 34.75%, 28.41%, 21.80% and 10.29% respectively. Wheat varieties showed no significant effect on straw yield, however variety Sujata recorded higher straw yield as compared to variety MP 3173 and MP 3288. Different wheat varieties showed significant effect on harvest index. Variety MP 3288 recorded significantly higher harvest index (34.96) followed by MP 3288 (33.90). Variety Sujata recorded lowest harvest index (32.51).
