1. Direct onion sowing under soil tillage methods
ABSTRACT Onion production is conditioned to the adopted techniques during the cultivation. Sowing depth, soil preparation and cultivars are determinant factors for productivity to be increased. Two experiments were developed, the first with the objective of evaluating the effect of sowing depths and soil preparation methods on the germination and development

2. Agronomic performance of watermelon under direct sowing system and seedling transplanting
RESUMO A melancia é tradicionalmente cultivada por semeadura direta, porém, em função do alto valor das sementes de materiais melhorados, o transplantio de mudas é alternativa promissora. Este trabalho teve como objetivo avaliar, em dois ciclos de produção, o desempenho agronômico da melancia por semeadura direta e transplantio de mudas. Os experimen

3. SIMULATING CROP YIELD, SOIL NITROGEN, AND ORGANIC CARBON IN NO-TILLAGE CROP SEQUENCES IN A SUBTROPICAL CLIMATE IN BRAZIL
ABSTRACT Brazil stands out worldwide for its high grain production in areas of direct sowing. The objective of this study was to simulate and assess the relationship of soil organic carbon content and nitrogen, crop yield, and biomass of two crop sequences under the no-tillage system in a subtropical region of São Paulo, Brazil, using CSM-CROPGRO-Soybean an

4. Direct selection for phenotypic traits in carrot genotypes
RESUMO A seleção de genótipos de cenoura mais produtivos é fundamental para os programas de melhoramento dessa cultura visando aumento na produção com redução dos custos. Assim, objetivou-se com esse trabalho avaliar o ganho com a seleção direta e medir seus efeitos em outras características agronômicas de interesse em cenoura. Para isso, 36 gen�

5. Influence of Tillage Systems and Selective Herbicides on Weed Management and Productivity of Direct-Seeded Rice (Oryza sativa)
RESUMO: Plantas daninhas causam dano considerável à colheita de arroz. Para averiguar a influência de diferentes práticas de manejo de plantas daninhas sob diferentes sistemas de cultivo, um teste de campo foi conduzido durante 2014 -15. Como desenho experimental foram utilizados blocos inteiramente casualizados com parcelas subdivididas, cada uma de 6 x

6. Somatic embryos from Phalaenopsis classic Spotted Pink (Orchidaceae) protocorms
RESUMO: O presente estudo buscou induzir a formação de embriões somáticos em protocormos do híbrido Phalaenopsis Classic Spotted Pink em dois estádios de maturação fisiológica aos 80 e 120 dias após a inoculação das sementes (DAIS). Os protocormos foram inoculados em meio ½ MS suplementado com 0,1 mg L-1 de ANA e 3 mg L-1 de TDZ. Aos 15 dias de

7. Water use of cowpea under deficit irrigation and cultivation systems in semi-arid region
RESUMO A resiliência das culturas à seca depende fortemente das práticas culturais adotadas, as quais podem ter um efeito direto sobre a eficiência de uso da água. O objetivo deste estudo foi avaliar a influência de turnos de rega sobre o crescimento, consumo de água e eficiência de uso da água do feijão-caupi (cv. BRS Guariba) nos sistemas de plan

8. TRACTIVE DEMAND, SOIL MOBILIZATION PARAMETERS, AND CORN YIELD IN COMPACTED OXISOL
ABSTRACT Direct seeding systems are characterized by soil disturbance only occurring in the sowing line and the maintenance of the remaining area is achieved by covering with crop residues. Without total area soil mobilization as recommended by the no-tillage system, associated with the increase in the degree of soil compaction caused by the traffic of agric

9. Farmer rationality and the adoption of greening practices in Poland
ABSTRACT Common Agricultural Policy (CAP) reform in the European Union introduced a new element: greening. The aim of greening is to support the environment and create non-productive value in agriculture. The main element of greening is the Ecological Focus Area (EFA) meaning that a portion of farmland area has to be designed for environmental purposes. This

10. Enrichment of arbuscular mycorrhizal fungi in a contaminated soil after rehabilitation
Abstract Spore counts, species composition and richness of arbuscular mycorrhizal fungi, and soil glomalin contents were evaluated in a soil contaminated with Zn, Cu, Cd and Pb after rehabilitation by partial replacement of the contaminated soil with non-contaminated soil, and by Eucalyptus camaldulensis planting with and without Brachiaria decumbens sowing.

11. Genetic divergence among maize hybrids by morphological descriptors
Two experiments with 25 maize commercial hybrids were carried out in a direct sowing system in Southern Brazil in the harvests of 2009/2010 and 2010/2011. Quantitative descriptors were used with the objective of determining the genetic divergence and the relative contributions of traits among hybrids for extraction of inbred lines. This study was carried out

12. Requerimientos ambientales para la germinación de sphaeralcea bonariensis
S. bonariensis (white mallow), tolerant to glyphosate, is important for the practice of direct sowing in Argentina. The germinating behavior of the species at different temperature conditions (namely 5, 10, 15, 20, 25, 30, 35, 40, 20/10, 25/15, and 30/20°C in a 12 hour photoperiod of light); saline stress (0, 30, 50, 70, 90, 130, and 150 mM of sodium chlori
