The effects of intra-row spacings and cutting heights on the yields of Leucana leucocephala in Adana, Turkey

Abstract

This research was conducted in Adana, Turkey, between 1985 and 1987. The study investigated the effects of the intra-row spacings and cutting heights on yields of 2 cultivars of Leucaena leucocephala, K8 and Peru. The trial was a split-split plot design in randomized blocks with 4 replications. The main plots were the cultivars, K8 and Peru; subplots were intra-row spacings, 25, 50, and 75 cm; and sub-sub plots were cutting heights, 20, 40, and 60 cm. Row spacing was 1m. Peru had higher leaf yields than K8. Increased intra-row spacing decreased both thin and thick dried stem yields and foliage yield per ha. The effects of cutting heights varied with the years. The highest dried foliage yield was obtained from the plots cut at 40 cm in the first year and 60 cm in the second year.
