Nutritional requirements of vegetables grown on noncoastal regions of Guyana have not been established. The present study was conducted on a major soil type in these areas, a Tiwiwid sand (Typic Quartzipsamments) to evaluate the effects of fertilizer rate and placement and fritted trace element (FTE 503)4 rate on nutrient uptake, root distribution, and yield of snap beans (Phaseolus vulgaris L.). Fertilizer levels were 79-67-112 and 158-67-224 kg/ha on the area fertilized and were applied on one-third, two-thirds, and the full bed. FTE 503 treatments 44.8 kg/ha and no application.
Snap bean yields were reduced from 1,008 kg/ha at the lower fertilizer rate to 727 kg/ha at the high rate. With the application of FTE 503 and the low fertilizer level, yields increased with an increase in the width of the fertilizer band. At the high fertilizer rate, yields were reduced with an increase in the width of the fertilizer band. Application of FTE 503 increased the average dry weight of bean plants from 0.55 to 1.07 and from 1.94 to 5.17 g/plant at the flowering and pod set stages, respectively. Yield increases due to FTE 503 applications were from 216 to 1,800 kg/ha and from 26 to 1,428 kg/ha, when fertilizer rates were 79-67-112 and 158-67-224 kg/ha, respectively. Mean root concentration in the surface 30 cm of soil were increased from 1.39 to 1.82 cm root/cc soil with an application of FTE 503. Results indicated that application of FTE 503 corrected micronutrient deficiencies and improved the availability of soil water and nutrients.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
