The efficacy of using crop cover in controlling viral diseases of squash was studied under field conditions. Results of the study revealed that crop cover of 15 to 30 d delayed the onset of disease incidence, spread and severity of viral diseases, leading to improvement in vegetative growth and consequently, to increase and subsequent improvement in fruit yield and quality. It was observed that 21 d was the optional coverage period for higher fruit yield. Vegetative growth and fruit yield and quality did not differ significantly for plants under cover for IS d and 30 d.

Tomato Cultivars

Fourteen tomato cultivars resistant to tomato spotted wilt tospovirus (TSWV) were evaluated for their tolerance against tomato chlorotic spot tospovirus (TCSV) under field conditions during the 2014–2015 and 2015–2016 growing seasons in Homestead, FL. All TSWV-resistant tomato cultivars had significantly (P < 0.05) lower disease incidence of TCSV, compared with the commercial standard cultivars ‘FL 47’ or ‘Sanibel’, exhibiting intermediate to high levels of tolerance to TCSV. There was no significant effect of tomato genotype on the thrips vectors, western flower thrips (Frankliniella occidentalis) and common blossom thrips (F. schultzei). All tested tomato cultivars had equivalent or greater yields of total marketable fruit compared with the standard cultivar Sanibel. Particularly, in the third trial with disease incidence of 25% on Sanibel, ‘BHN 1064’ had significantly greater total yield and yields of extra-large and large fruit compared with Sanibel. ‘SV 7631TD’ and ‘Brickyard’ had significantly greater extra-large fruit yield and medium fruit yield, respectively, compared with Sanibel. Results from this study show that TSWV-resistant tomato cultivars were tolerant to TCSV under field conditions of south Florida, indicating that the use of genetic resistance in commercial tomato cultivars is an effective strategy to manage TCSV.

Swingle Citrumelo

‘Valencia’ sweet orange is widely cultivated in Colombian tropical lowlands, with low yields and a lack of technology. As a result, nine rootstocks commonly used in tropical zones: ‘C-35’, ‘Carrizo’, ‘Swingle’ citrumelo or CPB 4475, ‘Cleopatra’, ‘Sunki ´ English’, ‘Volkamer’, ‘Webberi’ and ‘Yuma’ were evaluated. The plants were established in 2001 and were evaluated for vegetative growth, fruit yield and quality for 10 years (2004-2013). The obtained results indicated that ‘Sunki × English’ and ‘Volkamer’ were the best rootstocks for fruit yield and the worst was ‘Yuma’. Furthermore, all of the rootstocks, except ‘Yuma’, stabilized their height in the last year. In terms of volume, ‘Amblycarpa’ and ‘Cleopatra’ were the bigger plants and ‘Yuma’ was the smallest. In addition, for yield efficiency, ‘Yuma’ had the best rootstocks, followed by ‘Sunki × English’. All of the rootstocks showed a similar fruit quality, except for ‘Sunki × English’, which obtained the highest total soluble solids/total titratable acids ratio.

The use of agricultural waste is of great interest to sustainable agriculture. An investigation was carried out to evaluate the effects of compost and compost tea made from agricultural waste rice straw on the yield and quality of two horticultural crops strawberry and tomato. In strawberry experiment, six treatments were considered which wereT1: 100% soil (as a control), T2: 80% soil + 20% compost, T3: 60% soil + 40% compost, T4: 40% soil + 60% compost, T5: 20% soil + 80% compost & T6: 100% compost. Results revealed that number of fruit, fruit yield and total sugar (%)was increased with the increasing level of compost up to 80% after that decreased at 100% compost. The treatment T5: 20% soil + 80% compost gave the best results among the treatments to grow strawberry with good yield (185.3 g/plant) and sweetness (total sugar 5.19%). On the other hand, six treatments i.e. T1: Control, T2: Compost (5 t/ha), T3: Compost tea (50% concentration), T4: Compost (5 t/ha) + Compost tea (50% concentration), T5: Compost tea (100% concentration) and T6: Compost (5t/ha) + Compost tea (100% concentration) were considered in tomato experiment. As a result, it was observed that combined application of compost (5 t/ha) along with compost tea (100% conc.) (T6) gave the highest yield of tomato than not only control (T1) but also single application of compost or compost tea (T2, T3, T4&T5). Level of compost tea concentration also showed significant effect on fruit yield of tomato. Comparing between treatment T4 and T6, fruit yield was found higher (1027.67 g/plant) in treatment T6: Compost (5t/ha) + Compost tea (100% conc.) than 961.3 g/plant in T4: Compost (5 t/ha) + Compost tea (50% conc.). So, it could be summarized that use of rice straw as compost and compost tea affects positively both in two experiments. The results of this study confirm the beneficial effects of compost to increase the yield and sweetness of strawberry and combination of compost and compost tea to increase the yield of tomato.
