thrse high management crops planted in sequence ("bulb onion-pole bean- 

 collard) , and three low management crops planted in sequence (English 

 pea-southern pea-southern pea) . The other two cropping patterns were 

 a combination of low, medium, and high management crops planted in 

 sequence as follows: HM-MM-LW (bulb onion-squash-southern pea) , and 

 HM-M-MM (bulb onion-southern pea-mustard) . These patterns were designed 

 to estimate the effect of crop management sequences on resoiorce use, 

 total productivity, and profitability. 



The four cropping patterns were arranged in a randomized block 

 design with four replications. Each plot measured 21 k long by ^ m 

 wide. Rows were oriented in an east-west direction. Bulb onion, 

 southern pea, English pea, squash, and mustard were field-seeded on 

 raised beds using an Earthway seeder. Pole bean was hand-seeded into 

 holssi2:-CinLdeep. Collards were grown in peat pots and transplanted 

 after 30 days. Planting practices and seeding rates were based on 

 recomirtanded practices (109, HO, I?!). 



Crops were planted in a single row per bed, except for bulb 

 onion which was seeded in double rows. Each plot consisted of three 

 beds ^0 cm wide and 15 cm high spaced 1.10 m apart. A 5-ni section 

 of the center bed was harvested for yields. 



Fertilizer rates for each crop (Table 1) were based on fertilizer 

 and vegetable production studies conducted in Florida (21, 56, 58, 59. 

 60, 74, 93. 159. 168). Basal fertilizer for each crop was applied and 

 incorporated into the soil prior to planting. Depending on the crop, 

 supplemental fertilizer was sidedressed or topdressed one or three 

 times during each crop cycle. Insects and diseases were controlled
