Thus, the objective was to evaluate the production of zucchini trunk (Cucurbita pepo) comparing the conventional cropping systems and direct planting. This experiment was conducted in the Experimental Campus UTFPR - Two neighbors under a Red Nitosoil. The experimental design was randomized blocks with split plots. We evaluated two systems of cultivation, direct and conventional drilling. In the winter period were used cover crops of single oat in Conventional Planting - (CP) and Direct Planting (DP) and a consortium of oat, vetch and radish also implemented in DP. We performed two periods of fertilization located in pits: one before crop sowing of winter covers (Advance) and another shortly after management with roller-knife prior to sowing squash (Normal). The organic fertilization was resulted from composting poultry litter. The culture of zucchini was implanted in September. The harvest fruit was made when the same achieved commercial standard between 15 and 20 cm. After termination of the cycle of zucchini whole area was weeded and received a polyculture corn + leguminous, corn being deployed in the same pits that contained zucchini and legume cultivation between rows. The variables analyzed were the fruits: mass (kg), circumference (cm) length (cm), number of fruits and cycle. The assessment of soil refers to the stock of carbon (C) and nitrogen (N) of the soil and the organic matter fractionation. The cover crops were evaluated for the production of dry matter and the content of N in vegetable waste. The systems of management of soil and fertilization times interfered in the length and number of fruits produced. The tillage system was more productive at the end of the experiment. The concentrations of N and C of the soil and the COP were not influenced by tillage systems and times of fertilization. The early fertilization affected the levels of N in the soil after three cycles of cultivation, being smaller than the system of regular fertilization. O uso de diferentes técnicas conservacionistas propicia condições de manutenção do potencial produtivo dos solos, merecendo atenção de pesquisas na área. Dessa forma, objetivou-se avaliar a produção de abobrinha de tronco (Cucurbita pepo) comparando os sistemas de cultivo convencional e plantio direto. Foi desenvolvido um experimento no Campus Experimental da UTFPR - Dois Vizinhos sob um Nitossolo Vermelho. O delineamento utilizado foi de blocos casualizados com parcelas subdivididas. Foram avaliados dois sistemas de cultivo do solo, plantio direto e convencional. No período hibernal foram utilizadas as culturas de cobertura de aveia solteira em Plantio Convencional – (PC) e Plantio Direto (PD) e um consórcio de aveia, ervilhaca e nabo implantado também em PD. Foram realizadas duas épocas de adubação localizada em covas: uma antes da semeadura da cultura de cobertura hibernal (Antecipada) e outra logo após o manejo com rolo-faca antecedendo a semeadura da abobrinha (Normal). A adubação orgânica foi resultante de compostagem de cama de aviário. A cultura da abobrinha foi implantada no mês de setembro. A colheita dos frutos foi efetuada quando os mesmos atingiram padrão comercial entre 15 e 20 cm. Após o término do ciclo da abobrinha toda a área foi capinada e recebeu um policultivo de milho + leguminosa, sendo o milho implantado nas mesmas covas que comportava abobrinha e a leguminosa na entrelinha de cultivo. As variáveis dos frutos analisadas foram: massa(kg), circunferência (cm), comprimento (cm), número de frutos e ciclo. As avaliações do solo se referem ao estoque de carbono (C) e nitrogênio (N) do solo e ao fracionamento da matéria orgânica. As culturas de cobertura foram avaliadas quanto a produção de matéria seca e teor de N nos resíduos vegetais. Os sistemas de manejo do solo e épocas de adubação interferiram no comprimento e no número de frutos produzidos. O sistema convencional de cultivo foi o mais produtivo ao final do experimento. Os teores de N e C total do solo bem como o COP não foram influenciados pelos sistemas de manejo e épocas de adubação. A adubação antecipada afetou os teores de N do solo após três ciclos de cultivo, sendo menores que o sistema de adubação normal. 2013-10-29T11:08:46Z 2013-10-29T11:08:46Z 2013-07-12 masterThesis BIANCHINI, Cristiano.

The use of different conservation techniques provides conditions to maintain the
productive potential of soils, deserving attention of the researches in the area. Thus, the objective was to evaluate the production of zucchini trunk (Cucurbita pepo)
comparing the conventional cropping systems and direct planting. This experiment
was conducted in the Experimental Campus UTFPR - Two neighbors under a Red
Nitosoil. The experimental design was randomized blocks with split plots. We
evaluated two systems of cultivation, direct and conventional drilling. In the winter
period were used cover crops of single oat in Conventional Planting - (CP) and Direct
Planting (DP) and a consortium of oat, vetch and radish also implemented in DP. We
performed two periods of fertilization located in pits: one before crop sowing of winter covers (Advance) and another shortly after management with roller-knife prior to
sowing squash (Normal). The organic fertilization was resulted from composting
poultry litter. The culture of zucchini was implanted in September. The harvest fruit
was made when the same achieved commercial standard between 15 and 20 cm.
After termination of the cycle of zucchini whole area was weeded and received a
polyculture corn + leguminous, corn being deployed in the same pits that contained
zucchini and legume cultivation between rows. The variables analyzed were the
fruits: mass (kg), circumference (cm) length (cm), number of fruits and cycle. The
assessment of soil refers to the stock of carbon (C) and nitrogen (N) of the soil and
the organic matter fractionation. The cover crops were evaluated for the production of
dry matter and the content of N in vegetable waste. The systems of management of
soil and fertilization times interfered in the length and number of fruits produced. The
tillage system was more productive at the end of the experiment. The concentrations
of N and C of the soil and the COP were not influenced by tillage systems and times
of fertilization. The early fertilization affected the levels of N in the soil after three cycles of cultivation, being smaller than the system of regular fertilization. |
