Produção do tomateiro em função dos sistemas de condução de plantas

Abstract

Fruits production of tomatoes as a result of plant training systemsThe effect of plant staking and training methods was studied on fruit yield and quality of four tomato cultivars. and two training methods (one and two stems per plant keeping the same number of stems per area), using the sub subplots experimental design. There was no statistical interaction between cultivars, training methods and among staking methods. The vertical staking with bamboo increased the production of fruits, when compared with other staking methods, and all vertical-staking methods increased the production of fruits, when compared to the crossed fence method. The training method with one stem per plant increased the production of fruits, when compared to the training method with two stems per plant.

Weed Interference in Eggplant Crops

“…The high density of C. rotundus might be related to the particular characteristics of the crop management, such as plant staking and sprout thinning, which favor greater light penetration and aeration in the growing area (WAMSER et al, 2007;MIRANDA et al, 2011), in addition to tuber fragmentation caused by hand-weeding, which increases C. rotundus regrowth. ).…”

“…Crop management practices, such as plant staking and sprout thinning, might have positively influenced this result, reducing the period needed for control. This phenomenon might occur because plant staking helps to limit the severity of disease or pest attack (WAMSER et al, 2008), and enhance the distribution of solar radiation across the crop canopy (WAMSER et al, 2007). Moreover, plant staking facilitates the aeration of crops, which increases fruit size and decreases attacks by pests (CECÍLIO FILHO, 2009).…”

“…These management practices are beneficial to the crops and affect weed control, as they alter environmental factors within the crop. For example, in tomato production systems, plant staking improves how solar radiation is distributed across the plant canopy (WAMSER et al, 2007). Furthermore, sprout thinning prevents leaves and fruits touching the soil and improves aeration, enhancing solar radiation to the plant and the implementation of cultural practices (MIRANDA et al, 2011).…”

Sistemas de tutoramento e épocas de transplante de physalis

“…Inicialmente, o esperado para as variáveis relacionadas com a produção, produtividade estimada e eficiência produtiva, era que os valores mais representativos fossem obtidos nos sistemas verticais associados à primeira data de transplante. Isso ocorre devido ao fato destes sistemas serem considerados os mais produtivos na cultura do tomateiro (cerca de 30% superior) e apresentarem a característica de facilitar o manejo bem como promover melhor aeração e penetração de luz nas plantas (SANTOS et al, 1999;WAMSER et al, 2006;SILVA et al, 2008). Além disso, as plantas transplantadas em novembro (primeira época de transplante) foram submetidas a temperaturas próximas às ideais ao cultivo (25°C) e a um maior período livre de geadas.…”

Produtividade de tomate orgânico cultivado em diferentes ambientes e níveis de insumos

“…Além de ter custo de produção menor, o cultivo de tomate à campo sob manejo adequado pode se obter produtividade superior ao ambiente protegido (WAMSER et al, 2007). Segundo Reis et al (2012) o ambiente protegido em cultivo de tomate promove redução considerável na irradiação solar global, com transmitância média do polietileno de 62%, mas que pode ser compensado pelo aumento na fração solar difusa com maior contribuição na faixa do visível (radiação fotossintética).…”
