Tomatoes and peppers are the most popular and profitable high tunnel crops. However, year-round intensive cultivation and extensive monocropping can lead to a loss of soil quality and the buildup of soilborne pathogens. Many growers are considering grafting to help address the drawbacks of covered agriculture and improve yields. Although many trials have been conducted that examine the ability of rootstock to increase yield or reduce disease, the effect of scion cultivar has yet to be tested, and few studies have attempted to quantitatively assess scion compatibility. In 2016 and 2017, we evaluated ten hybrid, determinate, red slicing tomato scion cultivars for compatibility with 'Maxifort' rootstock in a three-season high tunnel in Olathe, KS. While all ten varieties were compatible with 'Maxifort', only 'BHN 589', 'Red Deuce', 'Skyway', and 'Tasti Lee' were "highly compatible" and showed significant improvements in marketable yield when grafted. Additionally, when ranked by yield, differences between grafted and nongrafted populations suggest that relative compatibility may be inconsistent between varieties. However, a significant inverse relationship between the yield of the nongrafted plants and the percent yield benefit from grafting indicates that the effect of a rootstock like 'Maxifort' may not be synergistic, with higher performing nongrafted scion varieties benefitting less from grafting than lower performing varieties. 'Red Deuce' and 'BHN 589' are productive, and highly compatible grafted varieties with potential for commercial high tunnel production. 'Primo Red' benefitted the least from grafting but was the highest performing nongrafted variety (outperforming four of the grafted combinations). Compared to tomatoes, published reports on grafted peppers have been limited and it is unclear whether they provide any advantage in the absence of soilborne disease or environmental stress. Additionally, the use of rootstocks from other solanaceous species outside the Capsicum genus for pepper grafting has not been well explored, though the pool of available rootstock options for peppers would be substantially increased if such graft unions proved to be compatible. The goals of a second project were to identify the utility of grafted pepper (C. annum) plants for commercial high-tunnel production and to explore the potential for graft compatibility between the Capsicum and Solanum genera. We grafted 'Karisma' bell peppers onto two Solanum cultivars ('Maxifort' and 'Sweetie') and three pepper rootstocks ('Scarface', 'Meeting', and 'Yaocali'). Five trials were conducted in 2016-2017 and utilized a randomized complete block design in all locations. Plants grafted onto Solanum rootstocks displayed symptoms of delayed incompatibility, including significant (78%-89%) reductions in yield (by weight), 59%-93% less plant growth, and 58% less marketability, as well as malformations at the graft union and higher in-field mortality rates. These symptoms were likely due to differences in mature stem anatomy. Plants grafted to 'Scarface' produced 32% greater marketable yield, 15%-18% larger fruit, and 9-12% higher marketability than nongrafted 'Karisma'. The results for 'Yaocali' were similar to 'Scarface', though less conclusive. While 'Yaocali' and 'Scarface' rootstocks may be useful for improving yield in low-stress environments, the use of 'Meeting' may be more beneficial for combatting disease.

Grafting with inter-specific hybrid rootstock is effective for tomato (Solanum lycopersicum) growers looking to reduce soilborne disease organically and increase fruit yield in the Southeastern US. However, production with grafted tomatoes has not been tested in the Great Plains region of the US. Small-acreage growers would like to produce grafted plants themselves, but many have difficulty with propagation due to water stress in the scion post-grafting and/or high temperatures within healing chambers. Growers may be able to reduce water stress post-grafting by removing the upper portion of the shoot to reduce leaf surface area, but no data exist on the potential effects of this practice on mature plant yield. Five high tunnel and one open-field study were conducted in 2011 and 2012 to investigate yield effects related to the use of two rootstocks and shoot removal during the grafting procedure. Grafting significantly increased fruit yield in five of the six trials (P

Tomato is among the most important vegetables grown in Tanzania. However, production is strongly challenged by abiotic and biotic factors. Vegetable grafting has been used as an effective tool to combat abiotic and biotic factors while improving yield and quality. Yet, in Tanzania this is still a new technology, which needs to be explored in depth in order to be utilized effectively. The aim of this study was to evaluate the utility of grafting for improving yield and quality of tomato in Morogoro, Tanzania. The specific objectives were to: 1) evaluate grafting compatibility between tomato cultivars of commercial importance in Tanzania and the tomato germplasm line Hawaii 7996 and eggplant germplasm line EG195, 2) assess the effect of grafting with EG195 rootstock on plant growth and vigor of tomato cv. Tengeru97, 3) determine the effect on weed suppression of grafting ... Tengeru97 ... onto EG195; and 4) evaluate the effect of grafting with EG195 rootstock on yield and fruit quality of ... Tengeru97 ... tomato. Since low-resource farmers are unlikely to have access to sophisticated grafting facilities such as cooled healing chambers with humidifiers, the focus of the first series of experiments was to evaluate grafting success when graft healing was conducted in three locations. Although, graft healing was not successful in a shaded area outdoors, some grafting success was obtained indoors in a healing room, and even higher survival of grafted seedlings occurred when grafted plants were placed in a healing chamber within the healing room.

Growing tomato (Solanum lycopersicum L.) is a challenge in the short, cool growing season of northwestern Washington. This study investigated two fertilizer sources, conventional and integrated poultry-manure fertilizer, and grafting for effects on growth, N content, yield and fruit quality of tomato grown in a high tunnel in northwestern Washington. Conventional fertilizer was applied at 112N-74P-47K and 356 Ca kg.ha-1 in 2015, and 112N-62P-43K and 288 Ca kg.ha-1 in 2016. Integrated fertilizer was composted poultry manure applied at 2.4 t.ha-1 in both growing seasons (application rates were 12N-58P-26K and 344 Ca kg.ha -1 in 2015, and 17N-61P-43K and 295 Ca kg.ha-1 in 2016), plus urea fertilizer at 90 kg.ha-1 N. Grafting treatments consisted of 'Panzer' tomato grafted on rootstocks 'Estamino', Maxifort', 'DRO138TX', or non-grafted (control). Conventional fertilizer and grafting increased growth of tomato plants compared to the integrated fertilizer, and non-grafted plants. Grafted plants showed higher nitrate-N than non-grafted plants. Total and marketable fruit weight was higher for grafted plants than for non-grafted plants in the second growing season. Total soluble solids (TSS) and lycopene content were higher with integrated fertilizer, and for fruit from grafted plants. The healing process after grafting is a key factor impacting grafted seedling survival. A greenhouse study investigated the effect of different light (0%, 25%, 50%) and relative humidity (RH) (50%, 100%) levels in the healing chamber environment on the grafting success and plant growth of solanaceous vegetable crops. Survival and growth of grafted plants was greatest when the healing chamber environment was 50% light and 100% RH. Tomato and pepper had 14% greater survival rate on average than eggplant. It is not as critical to control light level in a healing chamber, but RH level can have a significant impact on graft survival, and different solanaceous vegetable crops may have different optimal environments for graft healing.
