“…The 2010-12 plasticulture trials were designed to determine the optimum in-row plant spacing and number of rows for cabbage grown using plastic mulch and drip irrigation (population trials). In-row plant spacings of 15, 20, 25, 30, and 35 cm and a 3-row or 4-row configuration were combined to make 10 spacing vs. row configuration treatments (Barrett et al, 2015). A 3-row or 4-row configuration with an in-row plant spacing of 25-35 cm was found to optimize crop yield; therefore, only these data were used in the current analysis.…”

“…As a result, differences in yield are expected between years and even planting dates within the same year. Barrett et al (2015) reported 34% and 42% reductions in yield in 2011-12 for cabbage planted in October and December, respectively, when compared with the yield in previous year planted in December. The warmer air temperatures in the 2011-12 growing seasons led to reduction of cabbage yield.…”

“…Moreover, the low cost of operation and ease of use associated with the bare ground system (Locascio, 2005) have not provided the necessary incentives to drive the adoption of a commercial plasticulture cabbage system. Barrett et al (2015Barrett et al ( , 2018) developed a drip-irrigated plasticulture system and nitrogen fertilizer rates to increase water and fertilizer use efficiencies while increasing plant population. In two follow up studies, Paranhos et al (2016aParanhos et al ( , 2016b examined the effects of planting date on plasticulture grown cabbage over the course of the entire Northeast Florida cabbage planting season and compared the profitability of cabbage grown using plasticulture and bare ground.…”

“…In two follow up studies, Paranhos et al (2016aParanhos et al ( , 2016b examined the effects of planting date on plasticulture grown cabbage over the course of the entire Northeast Florida cabbage planting season and compared the profitability of cabbage grown using plasticulture and bare ground. The objectives of this study were to compare yield and profit of the current bare ground cabbage production system used in Florida with the plasticulture system proposed in Barrett et al (2015) by using a model with stochastically simulated independent variables that are known to be correlated with yield. It was hypothesized that these models can predict yield based on specific weather parameters to assess the economic risk in cabbage production systems in terms of yield and profit and be used as a decision support tool for growers.…”

Weather has a major influence on cabbage (Brassica oleracea var. capitata L.) production. Variation in yield between years and cropping seasons is common in North America. Cabbage in Florida has historically been cultivated on bare ground with seepage irrigation. The objectives of this study were to compare yield and profit of a bare ground cabbage production system used in Florida with an alternative plasticulture system. Data from various cabbage trials were combined by production system and used to create regression equations that predicted yield based on air temperature and solar radiation that were significantly correlated with yield. The regression equations were then simulated with correlated stochastic air temperature and solar radiation to estimate the yield distributions for both systems. Cabbage price ($/Mg fresh) was stochastically simulated (correlated to yield) to be used in the profit model. The profit model was created by using the product of yield and the price per unit yield minus fixed and variable costs associated with production and marketing. Simulated profit for bare ground and plasticulture was used to estimate their respective distributions to provide a tool for making better management decisions in the presence of risky weather conditions. The plasticulture system was estimated to have a 36% higher cost but a 57% higher profit than the bare ground system. This is, in large part, because the simulated mean yield for the bare ground system was 29.7 Mg·ha−1 compared with 54.4 Mg·ha−1 for plasticulture. These findings confirmed that plasticulture is an economically viable best management practice for cabbage production in Northeast Florida.

“…Increase in planting density increases crop competition for nutrients, air, moisture, water and affects the size of the heads as well as cabbage yield (de Moel and Everaarts, 1990;Barrett et al, 2015).…”

Late cabbage forms a large above-ground mass which requires certain vegetation space in order to thrive. Late cabbage planting density should therefore, start from at least 70 cm inter-row and 50 cm intra-row spacing. Transplanting at the required spacing gives 28.600 plants per hectare. The required spacing provides proper plant development, the formation of rosettes (over 70-80 cm) with large leaves, and compact cabbage heads. Applying cultivation techniques needed for cabbage production and proper spacing results in the formation of regular head mass and expected yield of late cabbage. Proper spacing also provides better use of agricultural mechanization without damage to cabbage heads. On the other hand, higher planting density increases production costs of transplantation, cultivation practices, and workforce.
