Members of the genus Dioscorea, food yams, were introduced to Jamaica from Africa during the slave era and have remained a staple in local diets and national cuisine. Yam cultivation has also been an important economic activity providing employment for thousands of rural Jamaicans. Until the 1960s yams were grown for local use by subsistence growers for home consumption or by commercial growers...
Both the Vogel Spindle and Spanish Bush systems will allow for the development of a “pedestrian orchard”. A pedestrian orchard is defined as an orchard where two-thirds of the crop can be harvested from the ground, without the use of tall ladders (Fig. 1). Harvesting fruit from the ground greatly enhances worker productivity. In a study that I conducted in The Dalles, Oregon pickers were able t...
Genetically engineered crops were first commercialized in 1994 and since then have been rapidly adopted, enabling growers to more effectively manage pests and increase crop productivity while ensuring food, feed, and environmental safety. The development of these crops is complex and based on rigorous science that must be well coordinated to create a plant with desired beneficial phenotypes. Th...
Wild blueberries in Maine, USA are facing threats from our changing climate. While summer climate variations have been affecting this important commercial crop directly, significant other seasons also can be potentially detrimental to blueberry production. Therefore, we analyzed annual and seasonal trends (temperature, rainfall, snow cover) over the past 41 years (1980–2020) for seven Maine cou...
Advances in automation and data science have led agriculturists to seek real-time, high-quality, high-volume crop data to accelerate crop improvement through breeding and to optimize agronomic practices. Breeders have recently gained massive data-collection capability in genome sequencing of plants. Faster phenotypic trait data collection and analysis relative to genetic data leads to faster an...
An Expert System is a system that employs human knowledge captured in a computer to solve problems that ordinarily require human expertise. In agriculture, expert systems unite the accumulated expertise of individual disciplines, such as plant pathology, entomology, horticulture and agricultural meteorology and Animal Sciences; into a framework that best addresses the specific, on-site needs of...
(Note: Interest in planting cover crops has increased dramatically the past few years, not only in NYS but in ag regions across the US. Attendance at the Cover Crop & Soil Health session at the Empire State Producers’ Expo has been 90 – 100 the past few years. As growers returned to this practice they began to experiment with a wider range of cover crops than ever before, including brassicas li...
Palmer amaranth, a dioecious summer annual species, is one of the most trouble‐ some weeds in the agronomic crop production systems in the United States. In the last two decades, continuous reliance on herbicide(s) with the same mode of action as the sole weed management strategy has resulted in the evolution of herbicideresistant (HR) weeds, including Palmer amaranth. By 2015, Palmer amaranth ...
The alfalfa leafcutting bee, Megachile rotundata F. (Hymenoptera: Megachilidae), is widely used as a pollinator for production of alfalfa, Medicago sativa L., seed, and populations of these bees can be maintained by alfalfa seed growers or can be purchased from mostly Canadian bee providers. M. rotundata raised in Canada have higher survival rates during the incubation that occurs after winter ...
