Abstract:
The goal of this study was to compare the effect of leguminous and non-leguminous cover crops alone or in mixture with fertilizer nitrogen rates on above ground biomass, fruit number, and bell pepper yield. The following fall-spring fertility treatments were applied using randomized complete-block design with three replications: 1) fall-0 N, fallow, spring-0 N; 2) fall-0 N, abruzzi rye, spring-0 N; 3) fall-0 N, hairy vetch, spring-0 N; 4) fall-0 N, abruzzi rye+hairy vetch, spring-0 N; 5) fall-0 N, fallow, spring-84 kg·ha -1 N; 6) fall-0 N, abruzzi rye; spring-84 kg·ha -1 N; 7) fall-0 N, hairy vetch, spring-84 kg·ha -1 N; 8) fall-0 N, abruzzi rye+hairy vetch; spring-84 kg·ha -1 N; 9) fall-0 N, fallow, spring-168 kg·ha -1 N; 10) fall-0 N, abruzzi rye, spring-168 kg·ha -1 N; 11) fall-0 N, hairy vetch, spring-168 kg·ha -1 N; and 12) fall-0 N, abruzzi rye+hairy vetch, spring-168 kg·ha -1 N. In Spring 2003, `Camelott' bell pepper were transplanted. Total yield and fruit number were compiled over 8 weeks, while total vegetative dry matter was measured at final harvest. Highest above ground biomass (48.0 g/plant), total yield (36.7 Mg·ha -1 ) and fruit number (11/plant) were produced by fall-0 N, hairy vetch; spring-0 N. Lowest above ground biomass (19.0 g/plant), total yield (11.5 Mg·ha -1 ) and fruit number (4/plant) were produced by fall-0 N, abruzzi rye; spring-0 N. Hairy vetch without any additional N produced plant biomass, fruit number and yield better than all other treatments. Results indicate the legume cover crop can be an effective N source in supporting plant biomass, fruit number and yield of bell pepper.
