EFFECT OF PRUNING INTENSITIES ON TURMERIC IN DALBERGIA SISSOO BASED AGRISILVICULTURE SYSTEM IN CENTRAL INDIA

Abstract

 Dalbergia sissoo is a medium to large sized tree belonging to family – Leguminosae and subfamily Papilionioideae. It attains a height upto 30 m. This genus has about 300 species of tropical and sub-tropical timber tree species. It is having multiple uses such as fuel, wood, fodder, shade, and nitrogen fixing ability .The Present investigation was conducted in a Dalbergia Sissoo turmeric agrisilviculture system to find out Pruning effect on Turmeric yield and various growth characters of turmeric plants, respectively. The turmeric crop was sown in the interspace of a 16 year old Dalbergia sissoo plantation, planted at a spacing of 5mX5m. The effect of different pruning on fresh yield was found significant. The maximum fresh yield of rhizomes (3385.9 kg/ha) was measured under 25% pruning followed by 50% pruning (3221.3 Kg/ha), no pruning and open conditions. Whereas, the lowest fresh yield of rhizomes (2960.6 kg/ha) was recorded under 75% of pruning.
