Abstract:
... This paper presents the ALNS metaheuristics, employing the idea of DE to solve the mechanical harvester assignment and routing problem with time windows (HARPTW) to maximize the total area serviced by a mechanical harvester under a sharing infield resource system. The effective ALNS is designed to solve large-scale problems integrating the mechanical harvester assignment problem (HAP) and the mech ...

Abstract:
... The last few decades have seen a significant increase in the land under tea cultivation in the major tea growing regions of the world, mostly owing to the increase in the number of small-scale tea growers. These small-scale tea growers often resort to unsustainable agricultural practices. However, some of the growers in a few tea growing regions are converting to sustainable production systems lik ...

Abstract:
... Termites are eusocial arthropod decomposers, and improve soil fertility, crop yield, and also are used by humans for their benefits across the world. However, some species of termites are becoming a threat to the farming community as they are directly and indirectly causing major losses to the agricultural system. It is estimated that termites cost the global economy more than 40 billion USD annua ...

Abstract:
... Horseradish cultivars are highly heterozygous clones and are maintained through asexual propagation, using root cuttings. For many years, horseradish was believed to be sterile and therefore impossible to improve by traditional sexual crosses. Prior to the 20th century, the only way to improve horseradish was to select and plant root cuttings from the most desirable plants. Moreover, the developme ...

This will likely require changes in knowledge, and skills, of okra growers that can be accomplished by training. The study was conducted to identify the training needs of okra growers. Slightly more than half (54.6%) of okra growers required a medium l ...

Abstract:
... The current New Zealand Emissions Trading Scheme (ETS) allows forest growers to earn units under the stock change approach. Carbon price risk means that most participants are only trading safe units that they do not need to surrender after harvest provided that they replant. Consequently, the ETS has provided less incentive for afforestation than had been envisaged.This paper evaluates averaging a ...
