1. Hole spacing in soybean hill drop sowing1
ABSTRACT The aim of this study was to evaluate the development, yield and its components of soybean sown in hill drop method with variation in hole spacing, compared to the conventional sowing method in lines. The experiment was conducted in a randomized block design, with six treatments and four replications, using the variety M7739 RR IPRO with four plans

2. INFLUENCE OF SEED TUBE CURVATURE ON SEED LONGITUDINAL DISTRIBUTION
ABSTRACT Studies on the longitudinal distribution of seeds in the sowing row seek to improve crop homogeneity, thus generating high productivity. In this context, seed tubes must be analyzed for their angular curvature. Thus, this study aimed to evaluate the influence of the seed tube curvature on the longitudinal distribution of corn and soybean seeds at di

3. SEED METERING MECHANISMS AND TRACTOR-SEEDER FORWARD SPEED ON CORN AGRONOMIC COMPONENTS
ABSTRACT Seed metering system and tractor-seeder forward speed are factors that affect sowing. Therefore, this study aimed to evaluate sowing and agronomic components of corn as a function of seed metering mechanism and tractor-seeder forward speed, in addition to evaluating the yield data obtained from a harvester with a yield monitor. The soil of the area

5. Seed distribution by punch seeder in family farming
RESUMO A agricultura familiar busca utilizar práticas agrícolas menos agressivas, entretanto existem poucas máquinas adequadas à realidade deste segmento, isso tem levado ao uso de práticas tecnicamente incorretas, que vem contribuindo para o empobrecimento, compactação e desertificação dos solos agrícolas. Diante disso, as semeadoras puncionadoras

6. Seed spacing variability reduces common bean yield
RESUMO A distribuição irregular de sementes na linha de semeadura aumenta a competição intraespecífica das plantas por recursos ambientais, podendo reduzir a produtividade de grãos. Objetivou-se avaliar os componentes de rendimento e produtividade de feijão-comum, em função de coeficientes de variação (0 %, 20 %, 40 % e 60 %) das sementes na linha

8. QUALITY OF SEED DISTRIBUTION AT DIFFERENT SPACES BETWEEN BASE AND INTERMEDIATE BASE
ABSTRACT The aim of this study was to analyze the influence of space between the base and intermediate base on quality of seed distribution with a horizontal seed plate. The experiment was carried out in 2012 at the Laboratory of Agricultural Mechanization of the State University of Ponta Grossa - PR, Brazil, using a sowing simulation device. The experimenta

9. Densidade de semeadura e consÃrcio de braquiÃria e estilosantes visando à formaÃÃo de cobertura vegetal para a cultura da soja / Seeding density and consortium of brachiaria and stylosanthes aiming at vegetation cover to the soybean crop
The tillage efficiency is directly related to the management and choice of vegetation species prior to sowing the crop. In this context, this study examined the effect of brachiaria sowing densities (Brachiaria ruziziensis) (10; 15 and 20 kg ha-1), stylosanthes (Stylosanthes macrocephala and Stylosanthes capitata) (3; 4.5 e 6 kg ha-1) and consortium of these

10. Forage mass production and grazing loss of sorghum hybrid in response to the density of the sowing and the spacing between planting lines
The objective of this experiment was to evaluate dry matter yield and loss of grazing due to animal trampling in response to sowing density and spacing between lines in the planting. Sorghum hybrid 1P400 was submitted to six treatments, composed of three sowing density combinations (12; 16 and 20 kg/ha of seeds) and two spacing between lines (0.40 and 0.80 m

12. Influence of row spacing reduction on maize grain yield in regions with a short summer.
The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in t
