The objective of this study was to evaluate the efficacy of plant extracts in managing late blight disease in tomato, in vitro. Crude extracts were from Plectranthus barbatus, Tephrosia vogelii, Sphaeranthus suaveolens and Lantana camara. These were compared with commercial formulations Otiva fungicide and untreated as negative control. Their effectiveness was determined by measuring the inhibition zone of the mycelial growth of the pathogen recorded in triplicate at 48 hours and 72 hours. The results showed significant differences (P ≤ 0.001) among the extracting solvents on percentage inhibition of Phytophthora infestans. Methanol was superior in inhibiting the growth of mycelial growth of P. infestans as compared with ethyl acetate. Furthermore, all plants tested showed antifungal activity against P. infestans. The P. barbatus, L. camara and S. suaveolens were comparable with the commercial fungicide in inhibiting the growth of P. infestans. In this study, T. vogelii extract showed poor results in inhibiting the mycelial growth of P. infestans as compared with other plant extracts. Also, it was observed that, there were significant (P < 0.05) interactive effects between solvent and plant extracts and between incubation time and plant extracts. 展开更多

High tunnel production of horticultural food crops is becoming increasingly popular and has a significant impact on their growth, productivity and nutritional quality. The present study examines the effect of high tunnel production of lettuce (Lactuca sativa cv. “Two Star” and “New Red Fire”) and tomato (Solanum lycopersicum cv. “Celebrity” and “Mountain Fresh”) on their nutritional quality relating to major nutrients and health-promoting phytochemicals. High tunnel environment increased the concentration of N (protein) in both lettuce and tomato relative to the open field cultivation. The accumulation pattern of mineral nutrients in high tunnel was similar in green-leaf and red-leaf lettuce varieties. Lettuce varieties grown in high tunnel had higher accumulation of C, S and Zn relative to those grown in open field. However, high tunnel environment suppressed the accumulation of many micronutrients such as Mg, Fe, Cu and Mn in both lettuce varieties but not in tomato. For example, accumulation of Fe was reduced by more than 80% in “Two Star” and by more than 55% in “New Red Fire” under high tunnel. It also suppressed the levels of many health-promoting phenolic compounds such as chlorogenic acid, chicoric acid, rutin and kaempferol in green-leaf lettuce and gallic acid in red-leaf lettuce. High tunnel environment improved the soil nutrient status but reduced the radiation levels (PAR, UV-A and UV-B) received by the crops. The results show that the high tunnel production has a significant impact on the nutritional quality relating to protein and mineral nutrients in both crops and health-promoting phytochemicals in lettuce. 展开更多

Genetic variation developed in plant breeding programs is fundamental to creating new combinations that result in cultivars with enhanced characteristics. Over the years, tomato (Solanum lycopersicum) breeding programs associated with the Texas A&M University system have developed morphologically diverse lines of tomatoes selected for heat tolerance, fruit quality, and disease resistance to adapt them to Texas growing conditions. Here we explored the intraspecific genetic variations of 322 cultivated tomato genotypes, including 300 breeding lines developed by three Texas A&M breeding programs, as an initial step toward implementing molecular breeding approaches. Genotyping by sequencing using low coverage whole-genome sequencing (SkimGBS) identified 10,236 high-quality single-nucleotide polymorphisms (SNPs) that were used to assess genetic diversity, population structure, and phylogenetic relationship between genotypes and breeding programs. Model-based population structure analysis, phylogenetic tree construction, and principal component analysis indicated that the genotypes were grouped into two main clusters. Genetic distance analysis revealed greater genetic diversity? among the products of the three breeding programs. The germplasm developed at Texas A&M programs at Weslaco, College Station, and by Dr. Paul Leeper exhibited genetic diversity ranges of 0.175 - 0.434, 0.099 - 0.392, and 0.183 - 0.347, respectively, suggesting that there is enough variation within and between the lines from the three programs to perform selection for cultivar development. The SNPs identified here could be used to develop molecular tools for selecting various traits of interest and to select parents for future tomato breeding. 展开更多

Development of diseases in cultivated crops depends on the complex interrelationship among host, pathogen and prevailing environmental conditions. In nature, plants are rarely, if ever, subject to the influence of only one potential pathogen and this is especially true of soil-borne pathogens like fusarium wilt (Fusarium oxysporum). In the present study, the co-occurrence of root-knot nematode (Meloidogyne species) and Fusarium oxysporum f.sp. lycopersici was surveyed in the main tomato growing areas of the central rift valley of Ethiopia. Mineral and organic samples were collected from 59 farmlands representing five districts and two commercial farms during the main cropping season of 2017. Cultural, morphological and virulence analysis of these pathogens revealed their co-existence. Out of 59 samples, 39% were found infected with the disease complex [Meloilodogyne species.* Fusarium oxysporum f.sp. lycopesici (FOL)]. Off which, 16.9% and 6.8% resulted from concomitant infection of Meloidogyne incognita* FOL and Meloidogyne javanica* FOL, respectively. The percent prevalence of the disease complex ranged between 27.3% and 60%. The co-occurrence of these pathogens within a single host plant within the same ecological niche will indicate the probability of any type of interaction between each other. Therefore, subsequent research studies on their nature of interaction should be done in the future. 展开更多

There has been increasing interest in the quality of food produced in the sub-Saharan Africa and organic fertilizers can be used as palliative for eradicating malnutrition and improving the livelihood of the populace. A study was conducted in two phases, 4 × 5 × 2 and 2 × 4 factorial experiments in a completely randomized design with three replicates at the Department of Agronomy screenhouse, University of Ibadan, Nigeria. In the first experiment, five N levels (0, 20, 40, 60 and 80 kgN/ha) were combined with two P levels (0 and 20 kgP/ha) using urea and single superphosphate, respectively and four varieties (Roma VF, UC82B, Rio grande and Roma savana) of tomatoes were used. In the second experiment, optimum rates (60 kgN and 20 kgP/ha) from the first experiment formed the basis for the application of urea + SSP, urine + ORP, urea + SSP + urine + ORP and control. The best-performing varieties (Rio grande and Roma savana) in the first experiment were used. Data were subjected to analysis of variance. Combined application of N and P had higher N use efficiency and nutrient uptake than sole application of N or P. Urine + ORP based fertilizer mixtures were best for nutrient uptake and crop utilization of N and P. Increasing N levels led to decrease in nutrient use efficiency. Application of urine + ORP and urea + SSP gave better fruit qualities. The descending order of varietal superiority with respect to nutrient uptake, utilization and quality was: Rio grande > Roma savana > Roma VF > UC82B. Thus, urine + ORP based fertilizer mixtures have great potentials as substitutes for urea + SSP in the production of tomatoes. 展开更多

An experiment was conducted at Nagari union in Kaligonj Upazila of Gazipur district to determine the impact of Integrated Pest Management practices on tomato cultivation. Data were collected by using pre-designed interview schedule from 1st March to 5th August, 2014. The results of the study showed that in the study area farmers cultivated tomato in 14.6% of their land and there are eight IPM practices which are generally used by the farmers in their tomato fields. Regarding the overall adoption of IPM practices in tomato cultivation, 65.0% respondent farmers were in medium to high adoption category. The IPM Practice Use Index (IPUI) was found significantly higher in case of IPM adopters than in case of IPM non-adopters. But “use of pheromone trap”, “setting up the bamboo stick in the field” and “cultivation and use of green manure” were ranked as 1st, 2nd and 3rd, respectively in case of IPM adopters whereas “setting up bamboo stick in field”, “cultivation and using green manure” and “use quality and resistant seeds” obtained 1st, 2nd and 3rd rank, respectively in case of IPM non-adopters. The average infestation of insect and disease was found significantly lower in the fields of IPM adopter (9.7%) than IPM non-adopter (11.8%). The average frequency of chemical use in the season was also significantly lower in the fields of IPM adopter (2.14 times) than IPM non-adopter (3.44 times). The marketable yield was found significantly higher in the fields of IPM adopter (51.34 t/ha) than in the fields of IPM non-adopter (42.24 t/ha). The average gross return was also significantly higher in case of IPM adopter (526,143 taka/ha) than IPM non-adopter (472,647 taka/ha). The Benefit-Cost Ratio (BCR) of IPM adopter (2.41) was also found significantly higher than the BCR of IPM non-adopter (1.44). 展开更多

The objective of this work is to analyse the extent to which a change in the drying air velocity may affect the drying kinetics of tomato in a forced-convective solar tunnel dryer. 2 m?s?1 (V1) and 3 m?s?1 (V2) air speeds were applied in similar drying air temperature and humidity conditions. Main drying constants calculated included the drying rate, the drying time and the effective water diffusivity based on the derivative form of the Fick’s second law of diffusion. Henderson and Pabis Model and Page Model were used to describe the drying kinetics of tomato. We found that solar drying of tomato occurred in both constant and falling-rate phases. The Page Model appeared to give a better description of tomato drying in a forced-convective solar tunnel dryer. At t = 800 min, the drying rate was approximately 0.0023 kg of water/kg dry matter when drying air velocity was at 2 m/s. At the same moment, the drying rate was higher than 0.0032 kg of water/kg dry matter when the drying air velocity was 3 m/s. As per the effective water diffusivity, its values changed from 2.918E?09 m2?s?1 to 3.921E?09 m2?s?1 when drying air velocity was at 2 and 3 m?s?1 respectively, which is equivalent to a 25% increase. The experimentations were conducted in Niamey, on the 1st and 5th of January 2019 for V2 and V1 respectively. For both two experiments, the starting time was 9:30 local time. 展开更多

以一年两季设施番茄为对象,利用渗漏池收集渗漏液,研究了设施菜地不同灌溉模式(滴灌、漫灌)和施用有机物料(单施鸡粪M、鸡粪配施玉米秸秆M+C、鸡粪配施小麦秸秆M+W)对土壤矿质态氮、可溶性有机氮淋溶损失的影响。结果表明,日光温室栽培... 以一年两季设施番茄为对象,利用渗漏池收集渗漏液,研究了设施菜地不同灌溉模式(滴灌、漫灌)和施用有机物料(单施鸡粪M、鸡粪配施玉米秸秆M+C、鸡粪配施小麦秸秆M+W)对土壤矿质态氮、可溶性有机氮淋溶损失的影响。结果表明,日光温室栽培条件下,氮素的淋溶损失主要发生于秋冬季,滴灌和漫灌模式下,该季可溶性总氮淋失量占全年淋失量的56.8%和71.1%。漫灌模式下,冬春季和秋冬季可溶性总氮淋失量分别为114.3和281.1kg/hm^2,占单季氮投入量的12.5%和29.3%。与漫灌相比,滴灌使全年番茄产量和氮素吸收量分别显著提高15.6%和21.4%,氮素利用率(氮素吸收量/氮素投入量)显著提高47.5%,同时使全年矿质态氮(铵态氮+硝态氮)和可溶性有机氮淋失量分别降低68.6和47.4kg/hm^2,降幅分别为33.1%和39.6%。与单施鸡粪相比,鸡粪配施秸秆(玉米或小麦)对番茄产量无影响,但显著降低灌溉水渗漏量和氮素淋溶损失量,使全年灌溉水渗漏损失量平均降低24.3%,全年矿质态氮和可溶性有机氮淋失量分别平均降低26.6%和33.7%。综上,可溶性有机氮在氮素淋溶损失中不可忽视,滴灌模式通过降低渗漏液中氮的浓度,配施秸秆通过减少灌溉水的渗漏损失,进而降低可溶性氮的淋溶损失。 展开更多
