75 

 and K (low, medium, and high) were superimposed on each of the four 

 cropping pattern main plots. 



The longest cropping duration was 322 days in cropping pattern 

 HM-HM-HM, while the shortest diiration of 300 days was observed in crop- 

 ping patterns IM-M-IM and HM-LM-MM. Crops grown during winter had 

 prolonged growing periods which delayed the planting of second crops 

 in cropping patterns involving bulb onion. 



In general, marketable yields of vegetables were affected by 

 planting dates. Cropping patterns involving bulb onion resulted in 

 late planting and reduced yields of second crops. Cropping patterns 

 involving large crop residues also delayed planting of succeeding crops. 

 Bulb onion produced lower yield when planted after southern pea where 

 large crop residue remained in the soil than onion planted after collard 

 and mustard. 



High rainfall and temperature at flowering and pod set resulted 

 in low yields of pole bean in both years. Marketable yield averaged 

 only 1.7 metric tons/ha in 1977-78 and 1.5 metric tons/ha in I978-79. 

 These yields were lower than those obtained from normal spring planting 

 in Florida. 



Marketable yields of English pea were lower in 1977-78 than in 

 1978-79 because prolonged low temperature severely retarded early 

 growth which predisposed some plants to killing frost in January and 

 February . 



Yields of southern pea were not significsintly different between 

 years except in cropping pattern KM-MM-M. High residual nutrient 

 level in soil from previous squash and early planting dates contributed
