| Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercropped tomato and lettuce were evaluated during two seasons and compared to their sole cropping. The experimental design was a randomized complete block with nine treatments. The productivity and the classification of the tomato fruits were not influenced by having lettuce intercropped with it, but lettuce production was lowered when tomato was intercropped with it.... |

| O objetivo deste trabalho foi avaliar a capacidade combinatória de linhagens de tomateiro com hábito de crescimento determinado, com resistência múltipla a espécies dos gêneros Begomovirus e Tospovirus, e identificar combinações híbridas superiores. O experimento foi realizado em casa de vegetação, com 14 híbridos obtidos do cruzamento de sete linhagens femininas (grupo I) com duas linhagens masculinas (grupo II), em um dialelo parcial. As seguintes características agronômicas foram avaliadas: produção total, produção precoce, massa média de frutos, formato, firmeza inicial e firmeza na meia-vida. As linhagens genitoras TOM-680 e TOM-682, do grupo I, se destacaram por exibir as maiores estimativas de capacidade geral de combinação (CGC) quanto às... |

| We aimed to establish strategies for nitrogen (N) fertilization on drip-irrigated determinate-growth-habit tomato, under Cerrado conditions of Central Brazil. Three field experiments were carried out in a randomized block design. In experiment I six N doses (0, 80, 160, 240, 320 and 400 kg ha-1 N) were tested, in experiment II six combinations of the N forms (nitric; ammonium; amide; 2/3 nitric + 1/3 ammonium; 2/3 nitric + 1/3 amide; and 1/3 nitric + 2/3 amide) were evaluated, and in experiment III the combination of three soil pre-plant fertilization fractions (0, 20 and 40%) was evaluated with two splitting schemes of the remaining N via fertigation (linear and adjusted N-uptake curve). SPAD chlorophyll index and N content were measured in the leaves of... |

| The influence of irrigation depth was evaluated on tomato crop hybrid Debora plus for salad in a field experiment in split-block design with five treatments (irrigation depth of 40, 60, 80, 100 and 120% of crop evapotranspiration - ETc) and four replications. During the experiment, ten plant samples were collected to determine phytomass and leaf area to estimate plant growth parameters for different depths of irrigation. Results showed maximal growth between 70 and 80 days after transplanting in all treatments. Increase in irrigation depth above 80% of ETc increased crop growth rate (CGR), leaf area index (LAI) and total production of tomato fruits, although same commercial fruit yield was obtained with the lower depths. Therefore, an increase in depth of... |

| Se evaluó la respuesta del cultivo de tomate cherry a la biofertilización con microorganismos benéficos bajo condiciones de casasombra. Las semillas fueron inoculadas y co-inoculadas con Azospirillum brasilense (Az) y/o Glomus intraradices (Gi); después del trasplante, las plántulas de seis tratamientos recibieron dos aplicaciones de una solución conteniendo Az + Gi, y fueron comparadas contra el tratamiento testigo que solo recibió fertilización tradicional (NPK). La co-inoculación de las semillas con A. brasilense y G. intraradices más dos aplicaciones de Az + Gi a los 15 y 30 días después del trasplante, incrementaron en promedio 6% la altura de plantas, 11% el área foliar, 10,5% la biomasa seca y 16% el rendimiento de tomate cherry en comparación con... |

| ABSTRACT The production of horticultural crops in no-tillage and in rotation with cover crops reduces the dependency in nitrogen fertilizer, due to increased soil organic matter and by biological fixation performed by legumes. Thus, the aim of this work was to study rates of nitrogen fertilization and cover crops in the agronomic performance of tomato and broccoli grown under no-tillage. The experiment was conducted in a split plot design with four replications. Treatments consisted of cover crops, sunn hemp and millet, and four rates of nitrogen fertilization (0, 50, 100 and 200 kg/ha of nitrogen), for both the tomato and broccoli crops. All soil management was performed in no-tillage. For tomato crops we evaluated the plant growth, the nitrate... |

| ABSTRACT At present, Brazil is among the world's largest tomato producers. This production is directed both for the industry and for fresh consumption. Among the different tomato groups, production of mini-tomatoes has grown in recent years because of their high commercial value and mainly greater price stability. However, there are few studies investigating the proper management of this group, as it is recent in the country. The aim of the present study was to evaluate the viability of mini-tomato hybrids in different training systems, in greenhouse conditions. The experiment was set as a randomized block design in a 2×2×4 factorial arrangement with two numbers of stems (one and two stems per plant), two training systems [conventional (vertical) and... |

| The objective of this study was to evaluate the physiological performance of seeds and seedlings of tomato under the influence of different temperatures. The experiment was conducted in the Didactic Laboratory of Seed Analysis – ERS, UFPel. Gaúcho® tomato seeds were used. Treatments consisted of the constant temperatures 18, 20, 22, 24 and 26 ºC. To determine the physiological performance of the seeds and seedlings were employed germination assessments, first count, germination speed index, accelerated aging, cold test, shoot and primary root length, dry matter of roots and shoots, seedling emergence at 14 and 21 days after sowing, and emergence speed index. The results showed that tomato seed germination is not affected by the temperatures 18 to 26 ºC.... |

| ABSTRACT We aimed to determine an adequate planting density and arrangement for the mechanized spraying of vertically staked tomatoes. Two experiments were carried out in the 2013/14 and 2014/15 harvests in the city of Calmon, state of Santa Catarina, Brazil, both in randomized block design. In 2013/14, treatments were arranged in a 4x2 factorial, corresponding to four planting densities (10,753, 12,903, 16,129 and 21,505 plants/ha) and two planting arrangements (single and double rows). In 2014/15, treatments were arranged in a 5x2 factorial, corresponding to five plant densities (the same planting densities of the previous harvest beyond 32,258 plants/ha) and the same planting arrangements. Total, marketable (considering extra AA and extra A fruits as... |

| RESUMO: Pouco se sabe a respeito da influência do hábito de crescimento no desempenho agronômico de híbridos de minitomate. Diante disso, o objetivo do trabalho foi comparar o potencial agronômico de híbridos de minitomate, portadores do hábito de crescimento determinado versus indeterminado. O experimento foi conduzido em estufa plástica no Sítio São Roque, em Piracicaba-SP. Foi utilizado o delineamento em blocos casualizados com seis tratamentos (híbridos Rosso, Giallo, Verdi, Arancio, Candy e Mascot) e cinco repetições. A semeadura foi realizada em 27/02/2012, em bandejas de poliestireno. Decorridos 37 dias da semeadura, as mudas foram transplantadas para vasos plásticos de cinco litros. Foram avaliados o número de frutos/planta; número de frutos/m2;... |
