“…Similarly, Seliga and Shattuck [ 54 ] observed tomato colour was not impacted by previous crop, N rate (in 1 of 2 yrs) or their interaction. Likewise, others have seen no effect of cover crop treatment on tomato colour [ 36 ] or pH [ 36 , 40 , 55 ]. The lack of cover crop effect and cover crop interactions with N rate or cultivar interaction suggests limited impact of adopting cover crops into tomato production practices based on Agtron colour and pH fruit quality.…”

Much of cover crop research to date focuses on key indicators of impact without considering the implications over multiple years, in the absence of a systems-based approach. To evaluate the effect of three years of autumn cover crops on subsequent processing tomato (Solanum lycopersicum L.) production in 2010 and 2011, a field split-split-plot factorial design trial with effects of cover crop type, urea ammonium nitrate fertilizer rate (0 or 140 kg N ha -1 preplant broadcast incorporated) and tomato cultivar (early vs. late) was conducted. The main plot factor, cover crop, included a no cover crop control, oat (Avena sativa L.), winter cereal rye (hereafter referred to as rye) (Secale cereale L.), oilseed radish (OSR) (Raphanus sativus L. var. oleiferus Metzg Stokes), and mix of OSR and rye (OSR + rye) treatments. Cover crop biomass of 0.5 to 2.8 and 1.7 to 3.1 Mg ha -1 was attained in early Oct. and the following early May, respectively. In general, OSR increased soil mineral N during cover crop growth and into the succeeding summer tomato growing season, while the remaining cover crops did not differ from the no cover crop control. The lack of a cover crop by N rate interaction in soil and plant N analyses at harvest suggests that growers may not need to modify N fertilizer rates to tomatoes based on cover crop type. Processing tomato fruit quality at harvest (rots, insect or disease damage, Agtron colour, pH, or natural tomato soluble solids (NTSS)) was not affected by cover crop type. In both years, marketable yield in the no cover crop treatment was lower or not statistically different than all planted cover crops. Partial profit margins over both years were 1320 $ ha -1 higher with OSR and $960 higher with oat compared to the no cover crop control. Thus, results from a systems-based approach suggest that the cover crops tested had no observed negative impact on processing tomato production and have the potential to increase marketable yield and profit margins.

“…Figueiredo et al (2016) evaluated different genotypes of tomato for industrial processing and calculated an average productivity for the hybrids AP-529 and Tinto of 44.39 and 59.55 t/ha, respectively. Galvão et al (2013) analyzed industrial tomato hybrids with spacing of 1.5 m between rows and 0.30 m between plants under different types of ground covering, and recorded a productivity of 81.97 t/ha for the hybrid AP-529, 79.62 t/ha for AP-533, 65.33 t/ha for Kátia, and 57.69 t/ha for Sicílio in the fallow area. The results obtained in this study support those reported by the aforementioned authors.…”

Industrial tomato lines: morphological properties and productivity

The tomato is the second most produced vegetable in the world, with significant participation in the human diet. In addition, the production of tomatoes generates jobs and family income. The availability of improved cultivars that provide greater profitability to the producer and satisfactorily meets the needs of the fresh fruit market and the processing industry becomes imperative due to its importance. Therefore, this study aimed to characterize and select industrial tomato lines in regard to fruit yield, number of leaf branches, and number of flower racemes (NFR). The experiment was conducted in 2014 in the experimental area of the Federal University of Goiás (Universidade Federal de Goiás). The design was a randomized block design with four replicates and 25 genotypes. The number of leaf branches (NB), NFR, and fruit productivity were evaluated. The results were analyzed using analysis of variance and the means compared by the Tukey test. A difference was observed (P ≤ 0.01) for all traits analyzed. The NB and NFR were related, where more branches promoted an increase in NFR and thus the productivity increases. In addition, a greater number of fruits implied in smaller fruit size, and consequently lower fruit mass. The lowest number of fruit per plant caused increased fruit size and mass. The lines CVR 1, CVR 3, CVR 4, CVR 5, CVR 21, and CVR 22 were suitable for genetic enhancement of tomato and provided the greatest productivity.

“…Em condições edafoclimáticas semelhantes ao presente estudo, Faria et al (2007), avaliando atributos químicos de solo e produtividade do meloeiro, observaram que os adubos verdes exerceram efeito significativo sobre os teores de matéria orgânica na profundidade 0-10 cm em todos os tratamentos avaliados. Galvão et al (2013) avaliando diferentes adubos verdes (aveia preta, ervilhaca peluda, nabo forrageiro, trevo vesiculoso e vegetação espontânea) observaram aumento nos teores de MO do solo em todos os tratamentos, sendo o maior incremento apresentado pelo uso da aveia preta. Em relação ao manejo, observa-se também tendência do revolvimento do solo proporcionar maiores teores de MO, exceto na camada mais superficial do solo (0-5 cm).…”

“…Na camada de 10-20 cm, a VE e o CV2 proporcionaram os maiores teores desse elemento, enquanto na camada 20-40 cm os maiores teores foram observados nas parcelas com a VE e CV1. Galvão et al (2013) avaliando diferentes adubos verdes (aveia preta, ervilhaca peluda, nabo forrageiro, trevo vesiculoso e vegetação espontânea) observaram que o nabo forrageiro incrementou os teores de P no solo, na profundidade 0-20 cm, provavelmente devido a sua elevada capacidade de absorção em camadas mais profundas.

Artigo recebido em 12/04/2017 e aceito em 05/08/2017 R E S U M O O objetivo deste trabalho foi avaliar alterações em características químicas e na estabilidade estrutural do solo e, na produtividade da mangueira após cinco cultivos de dois tipos de coquetéis vegetais e manutenção da vegetação espontânea em dois sistemas de manejo do solo. O experimento foi conduzido no delineamento em blocos casualizados com quatro repetições, com os tratamentos dispostos em esquema de parcelas subdivididas. As parcelas foram constituídas por 2 sistemas de manejo (com e sem revolvimento do solo) e, as subparcelas por 3 tipos de adubação verde (CV1 -75% leguminosas + 25% gramíneas e oleaginosas; CV2 -25% leguminosas + 75% gramíneas e oleaginosas e uma vegetação espontânea (VE)). Em cada unidade experimental foram coletadas, nas entrelinhas das mangueiras, amostras indeformadas para avaliação da estabilidade de agregados e amostras deformadas para determinação dos teores de MO, Ca, Mg e K trocáveis, P assimilável e N total. As amostras foram coletadas nas profundidades 0-5, 5-10, 10-20, 20-40 cm. Foi avaliada também a produtividade da mangueira (t ha -1 ). Os cinco ciclos de cultivo sucessivos de coquetéis vegetais e de manutenção da vegetação espontânea alteraram os teores de P, MO e N. Os coquetéis vegetais promoveram maiores produtividades de manga em relação à vegetação espontânea, mas não alteraram a qualidade dos frutos. Palavras-chave: adubação verde, estabilidade de agregados, fertilidade do solo. Plant mixture and soil management systems changing soil quality and mango productivity A B S T R A C TThe aim of this study was to evaluate changes in chemical characteristics, soil structural stability and productivity of mango tree after five crops of two plant mixure types and maintenance of spontaneous vegetation in two soil management systems. The experiment was carried out in a randomized block design with four replications, with the treatments arranged in a split plot. The plot was set by two management systems (tillage and no tillage) and the subplots by 3 types of green manure (PM1 -75% + leguminous 25% grasses and oilseeds; PM2 -25% leguminous + 75% of grasses and oilseeds and spontaneous vegetation (SV)). In each experimental unit were collected between the lines of mango tree, undisturbed soil samples to assess the stability of misfolded aggregates and samples for determination of OM, Ca, Mg , K exchangeable, P assimilable and total N. The samples were collected from depths of 0-5, 5-10, 10-20, 20-40 cm. It also evaluated the productivity of mango tree (t ha-1). The five cycles of successive cultivation of plants mixture types and on spontaneous vegetation maintenance changed only the P, MO and N levels. The plants mixture promoted major mango productivity compared to spontaneous vegetation, but didn't change the quality of the fruit.
