Effects of vermicomposted spent mushroom compost on growing medium characteristics, plant growth, yield and abiotic stress tolerance
… mushroom compost increased shoot growth and marketable yield, and reduced blossom end rot in two independent studies. Vermicompost addition to peat-based growing media increased marketable yield by an average of 21%. Vermicompost also improved tomato fruit quality parameters such as acidity …

Manipulating Flowering Times and Site Attractiveness To Pollinators To Improve Yield and Fruit Quality in Strawberry
… the local strawberry season, maximize their yields though day-neutral production, and create a more pollinator-friendly production system. Fragaria x ananassa ‘Albion’ was planted in plasticulture in a RCBD in Ithaca, NY for the 2022 and 2023 growing seasons. Plants were sourced as four …

Fruit cluster pruning impacts on yield and quality of three tomato cultivars in an organic high tunnel system
The successful production of high-quality, high-yielding crops is important for fruit and vegetable producers, especially growers who use high tunnels. The valuable space within a high tunnel is well-suited to organic farming and can be used to grow many specialty crops. Fruit load management is …

Effect of planting depth and cutting orientation on growth and yield of sweet potato (Ipomoea Batatas L.(LAM) cultivars for small scale production in Verulam
… of South Africa. However, low storage root yields in small scale farming are attributed to a number of factors including poor selection of cultivars and possibly unsuitable cultivation practices. Therefore, two experiments were conducted over two growth seasons (2014/2015 and 2015/2016) to …

The effectiveness of biological control of Frankliniella occidentalis in prevention of the spread of Tomato spotted wilt virus
… weekly proportion of infected plants, and total marketable yield. The effects of different virus introduction methods were also compared. A comparison of virus introduction methods showed that, among all plants, the average number of weeks they were infected by TSWV was significantly lower when …

Alternaria Leaf Blight and Head Rot of Broccoli: UAV-Based Disease Detection and Fungicide Resistance Management
… rot (ABHR) of brassicas significantly impacts yield, threatening the sustainability of the broccoli industry. Management traditionally relies on quinone outside inhibitor (QoI) fungicides, but recent reports indicate reduced efficacy. The causes for this decline are unclear, whether due to a …

Effect of tillage system and nitrogen rate on tomato yield
… of other nutrients at Carrasco or Jackson. Total yield was not affected by the tillage systems except for Blacksburg in 1982 when the NT plots outyielded CT plots. Marketable yield was consistently increased by the NT system at all locations and years. Unmarketable yield was equal or higher with …

Recycling of domestic wastewater treated byvertical-flow wetlands for irrigating crops
… of various experimental systems in terms of marketable yields, the impact of differently treated wastewater on soil and fruit mineral and microbial contamination as a function of the wetland type as well as its operation and management, and the possibility of regenerating Capsicum annuum …

Developing methods of strip cropping cucumbers with rye/vetch
… petiole sap nitrate-nitrogen, soil moisture, yields and economic viability were assessed. Four treatments, namely cucumber direct seeded in black plastic mulch on tilled bare ground (conventional); cucumber direct seeded in black plastic mulch laid over incorporated rye/vetch residue; cucumber …

Host Range, Fungicide Resistance and Management of Pseudoperonospora cubensis, Causal Agent of Cucurbit Downy Mildew
… to the non-treated control at all locations and marketable yield was significantly reduced in mefenoxam and pyraclostrobin plots in all locations except Florida. Fungicide efficacy trials in Sampson County, NC in 2005, 2006 and 2007 indicate that fungicides with active ingredients famoxadone, …

Evaluation of the cucumber germplasm collection for fruit yield and quality
Breeding for improved yield in cucumber (Cucumis sativus L.) has been one of the important objectives of cucumber breeding. Although the average yield of cucumber has increased by 100% over the last four decades, yield progress has remained flat in the past two decades. Thus, it is necessary to …

Integrated pest management of squash bug, Anasa tristis, for conventional and organic cucurbit systems in Virginia
… leading to leaf necrosis, seedling death, and yield loss. Currently, A. tristis management strategies in summer squash focus exclusively on insecticide applications. Given that continuous use of insecticides imposes negative side effects on many non-target species, the major objective of this …

Impact of Sweet Potato Feathery Mottle Virus and Micropropagation on Yield, Root Quality and Virus Incidence in Commercial Sweetpotato Production Systems
Reduction in yield and root quality (decline) in sweetpotato has been attributed to the accumulation of viruses and mutations. Three studies were initiated to assess the effects of mutations and viruses in sweetpotato. In the first study, to document the effects of decline over time, two …

Predicting the Spread and Management of the Cassava Brown Streak Disease Epidemic
… root tissue, which reduces both consumable and marketable yield. In 2004, CBSD emerged in Uganda and has since been spreading rapidly through previously unaffected regions of East Africa and into Central Africa. Preventing spread to West Africa is a major food security and development priority, …

Improving Uniformity of Potato Crops
… some tubers are too small or too large to be marketable. There are economic and environmental incentives to improve uniformity, thereby increasing the fraction of yield that is marketable. The potato crop has a complex, three-tiered population structure consisting of plants, stems and tubers, …
