Book (stand-alone)A guide to good agricultural practices for commercial production of ginger under field conditions in Jamaica 2020
Also available in:
No results found.A guide to good agricultural practices for commercial production of ginger under field conditions in Jamaica introduces the utilization of the single bud technology in field production systems. This technology provides a means of multiplying the limited available clean planting material and its propagation under nursery conditions. This technology forms the basis of the ginger certification programme and when supported by Good Agriculture Practices (GAPs) as described herein should help ginger growers boost their levels of production. This information has been compiled predominantly from locally validated investigations and accepted norms in the ginger industry worldwide. It incorporates the use of technologies such as drip irrigation, integrated nutrition management and integrated pest management. The aim of this manual is to provide the user with a step-by-step process flow and thorough understanding of the processes and inputs involved in the application of the single bud technology in ginger field production systems. Please note that this system of production is new to Jamaica and warrants that interested growers receive training and conduct evaluations of this system first in their own environment. Care must be taken to ensure that the recommended practices are followed to achieve the desired result. -
DocumentThe early growth performances of Pinus densiflora and Larix kaempferi seedlings under open-field experimental warming and precipitation manipulation
XV World Forestry Congress, 2-6 May 2022

No results found.This study aimed to investigate the effects of climate change on the survival and growth performance of Pinus densiflora and Larix kaempferi seedlings using open-field experimental warming and precipitation manipulation. We measured the survival rate, root-collar diameter, and height, and then calculated the seedling quality index (SQI) of 2-year-old seedlings under 6 treatments [2 temperatures (TC: Control; TW: Warming) × 3 precipitation manipulations (PC: Control; PD: Decreased; PI: Increased)] and performed a two-way ANOVA to test for differences. The air temperature of the warming plots was 3°C higher than that of the control plots, while the precipitation manipulation plots received ±40% of the precipitation received by the control plots. Temperature and precipitation treatments did not significantly affect the survival rate of P. densiflora; however, the SQI of P. densiflora decreased with increasing precipitation. In contrast, the mortality rate of L. kaempferi increased with increasing temperature and decreasing precipitation. Furthermore, in L. kaempferi, TC × PI treatment resulted in the lowest SQI with a significant interaction effect observed between the two factors. In summary, low seedling production and quality should be expected in P. densiflora as precipitation increases and in L. kaempferi as temperature increases or precipitation decreases. These results indicate species-specific sensitivities to climate change of two plant species at the nursery stage. With the occurrence of global warming, the frequencies of drought and heavy rainfall events are increased, and this could affect the survival and seedling quality of tree species. Therefore, it is necessary to improve nursery techniques by establishing new adaptation strategies based on species-specific growth performance responses. 1) Keywords: Climate change ID: 3622385 -
