Description : Crop nutrient management is a critical component of productivity and quality. Commercial horticulture has relied almost exclusively on inorganic nutrient sources to satisfy plant nutritional requirements. Compost tea represents a sustainable alternative technology but its use has not been extensively researched. A factorial experiment was conducted subjecting lettuce plants to four increasing concentrations of compost tea; 0, 5, 10 and 20 % (m/v) applied at either 100 or 200 cm3 plant-1 day-1, for 30 days. At the end of the trial, measurements were made of leaf area (LA), yield, shoot and root dry mass (DM), root to shoot ratio, and nitrogen (N) and phosphorus (P) contents of shoots and roots. Compost tea concentration significantly (P < 0.05) affected all growth indices showing a similar pattern. Increasing concentration up to 10 % (m/v), positively improved growth and yield above the control. Increasing further to 20 % (m/v) reduced LA, yield and dry mass. For these variables, applying compost tea at 200 cm3 plant-1 day-1 resulted in a better response. Increasing concentration of compost tea showed a directly proportional relationship to shoot and root N content. However, the effect was non-significant for P. Yield and shoot DM were affected by the combination of compost tea concentration and application rate. Similar patterns of increasing yield were seen for increasing concentration within both rates however, the differences were significant for all concentrations at the higher application rate. Application of 200 cm3, 5 % compost tea resulted in the greatest yield, shoot and root DM. In addition to root DM, root surface area was significantly correlated with yield and shoot DM. Compost tea used at appropriate concentrations improved root growth and lettuce productivity.

Description : The Sargassum seaweed [Sargassum natans and S. fluitans] can be classed as a perennial invasive weed problem in all the Caribbean islands. It has been shown to affect fisher-folks, sea bathers, and tourists. It is proving to be costly to remove; in addition to its offensive odour which hampers the clean-up operations. The University of Trinidad and Tobago at the BAFT campus is engaged in series of activities to find suitable uses of the seaweed as animal feed, and as soil medium and ameliorant. This study aimed at evaluating the suitability of the seaweed as a growing media for the production of sweet peppers [Capsicum annuum var. annuum] using different percentage of the weed (0, 25, 50 and 100%) with soil under greenhouse conditions. The crop growth and development and yield were monitored. The results indicated that the plant height [Y pl ht = 16.6 + 0.3 DAT - 0.11 TRT] and leaf number [Y no.lvs = 0.90 + 1.04 DAT - 0.206 TRT] increased as age of the crop increased, but decreased with the increase in percentage of seaweed/ soil mixture. A similar response was observed for the flower buds and fruits numbers and percentage soil mixture. The medium had no effect on the crop transpiration and net photosynthesis rate [PN] , photosynthesis active radiation[PAR] , and stomatal conductance. A nutrient analysis of the medium was also conducted.

Description : Mulch application of Sargassum seaweed (Sargassum spp.) to soil can help to reduce beach contamination in the Caribbean Region while providing beneficial horticultural effects. This study investigated the effects of fresh Sargassum mulch on soil properties and plant growth in a test crop of tomato (Solanum lycopersicum L. â? ? HA 3019â? TM). Fresh Sargassum material (washed and unwashed) was applied as mulches (0, 5 and 8cm thick) to small field plots one week after transplanting of 3-week-old seedlings. The mulch material was raked away from the plots after three weeks exposure. Observations on soil moisture, electrical conductivity, pH and biological activity, and plant growth were made at 1 to 2-week intervals over a 6-week period with additional soil measurements after 10 weeks. Soil biological activity (respiration) was increased by the Sargassum mulch with values being similar for the 5cm and 8cm mulch layers. Soil moisture content, pH and electrical conductivity (EC) were increased as the mulch layer increased and EC values were only marginally reduced by Sargassum washing. An increase in plant growth compared to the control treatment was noted only in the washed Sargassum treatments. Potential benefits of Sargassum seaweed mulches on soil properties and plant growth can be nullified due to soil salinization effects.

Résumé : While Macfarlane's subdivision formed the center of West Tampa, the participation and investment of his partners were essential to Howard Avenue and Union Street the area's development, from Columbus Drive on the north to Fig Street on the south from the Hillsborough River on the east to Himes Avenue on the west. Dr. Philip H. Collins owned the subdivisions of El Cerro, Collins' Addition, and Collins' Second Addition. His son-in-law George Nelson Benjamin obtained two large subdivisions in 1892 from William B. Henderson. He ended these orange grove properties and promoted the growth of West Tampa's industry,serving also as Treasurer in the West Tampa Land Improvement Company and as Director of the Bank of West Tampa.

Description : French Overseas Départements are no longer islands as far as their economy is concerned : costs of transatlantic transportation has become too low to provide local productions with sufficient protection. The growth of local unemployment is a threat today for these societies. Producing new goods or services for export seems hardly conceivable for the time being, as french Overseas departments did not find any comparative advantage so far. So, recovering domestic market seems the only way to get jobs. But such a policy would require that would be allowed to raise customs to protect their domestic market : a change for a new status in E.U. law would be necessary, and these ultraperipherical regions would have to be changed into overseas countries and territories.
