GUAR CULTIVAR RESPONSES TO NITROGEN FERTILIZER RATES ON OOLITIC CALCAREOUS SOILS AND DISEASE INCIDENCE IN SOUTH FLORIDA

Guar (Cyamopsis tetragonaloba (L.) Taub), grown predominantly in India and Pakistan, is produced in Texas and Oklahoma, USA for seed.
It is tolerant to a variety of climates and soil conditions, and is grown throughout India as a fresh vegetable.
The Asian population familiar with guar as a vegetable, exceeds several thousand in the vicinity of Miami, thus a potential market for guar as a vegetable, exists.
Evaluations in 1987 showed that yields were not significantly affected by nitrogen (N) rates of 22, 66, and 110 kg ha^-1. Yields of cv. ‘Lewis’ were superior to ‘Esser’, ‘Brooks’, ‘Kinman’, ‘Santa Cruz’, and ‘Hall’. In the fall of 1991, ‘Lewis’, ‘Esser’, ‘Brooks’, and ‘Kinman’ treated with N rates of 66, 132 and 198 kg ha^-1 grew poorly apparently due to short day length effects in cultivars reported to have day-neutral flowering habits.
Throughout production areas, guar has potential as a cover crop and improves soils which are low in organic and nutrient contents.
