Interpretive Summary:

Technical Abstract: Two field plots were used to evaluate the effect of conventional monocropping system and low-input multiple cropping systems on sweet pepper growth and yield potentials. The low-input cropping systems involved the production of sweet pepper intercrop with swiss chard, or the intercrop with rosemary herb. The effects of the systems on yellow nutsedge control and some soil properties were also investigated. The study was conducted at Lorman, MS, on a Memphis silt loam soil. A completely randomized design was used in this study. Pepper seeds were grown in the greenhouse using ProMix Bx**a. Ten seedlings were transplanted in each row at a within-row distance of 1.22 m and between rows 1.07 m width. Each plant represented an experimental unit. Data collected on growth and canopy characteristics submitted to the USDA Natural Resources Conservation Service for use in developing databases for erosion prediction models. The effect of cropping system on root dry weight at 0-10 cm soil depth, total root fresh and dry weights were significantly higher for the herb-intercropping system. The highest values for plant height, canopy height, shoot fresh and dry weights were also for herb-intercropping system. The values for marketable and nonmarketable pepper fruit number and weight were higher (but not significantly) for the herb-intercropping. Sediments in runoffs from the plots, and nitrate-N in soils were highest for the monocropping system. Orthophosphate was highest in the vegetable-intercropping and monocropping system. Nutsedge infestation, soil temperatures, soil moisture and total runoff from plots were not different.
