Provedor de dados: 75
Autores: Lana,Milza M.
The effect of line spacing and harvest time on carrot and Cenourete®, a baby carrot-like product, yield were evaluated under conditions of Central Brazil winter. Seeds were sown in order to obtain 6, 8 and 10 lines/meter, what corresponded to a distance of 16.6, 12.5 and 10 cm between lines, respectively. Harvests were made 80, 90 and 100 days after sowing. The cultivars grown were open-pollinated Esplanada and hybrid SugarSnax 54. Root and Cenourete® yield varied with all the main factors and no interaction was significant. The root yield of both cultivars increased with later harvest at each density level. Yield of Esplanada root was only marginally affected by line spacing. Although significant, the effect of plant density on the yield of SugarSnax 54...

Provedor de dados: 75
Autores: Mota,Wagner F da; Pereira,Rosimeire D; Santos,Gizeli de S; Vieira,Janiele Cássia B.
The study aimed to evaluate the agronomic and economic performance of intercropping onion and lettuce on four plant densities of each species. The experiment was set up in completely randomized blocks, with four replications and treatments arranged in a 4 x 4 factorial. Treatments resulted from a combination of four (100, 80, 60, and 40% of recommended plant densities in monoculture) plant densities for both lettuce and onion. Intercropping did not affect the agronomic performance of onion or lettuce. Higher plant densities (100% for both vegetables) resulted in higher lettuce and onion yields. The best economic results were observed using (a) onion at 80% of plant density combined with lettuce at 40 and 100% and (b) onion at 100% and lettuce at all...

ABSTRACT Studies on the interaction between garlic plant density and virus-free seed size are scarce in Brazil. Thus, this study was installed to evaluate the effect of plant spacing and seed size on garlic traits and yield for infected and virus-free bulbs. Treatments were arranged in a randomized block design and 2x5x3 factorial combination [infected and virus-free bulbs, five plant spacings (210, 260, 300, 360, and 390 cm2 per plant), and three bulbous seed sizes (sieve one, two, and three)]. The highest bulb yield was observed for virus-free seeds at a plant spacing of 390 cm2 plant-1, while the highest commercial yield was verified for 210 cm2 plant-1 spacing. The combination of virus-free seeds, larger bulbs, and 332 cm2 plant-1 spacing promoted the...

Espaçamento e densidade para o cultivo do arroz de sequeiro na microrregião Alto Purus-Acre. II. Plantio em sulco.
Provedor de dados: 14
Autores: CAMPOS, I. S.; MEDEIROS, J. A.
A cultura do arroz no Acre, ainda não se reveste da importância econ6mica esperada, apesar de sua condição de cereal de alta produtividade e baixo custo de produção. Com o êxodo da população do meio rural para a cidade e outras regiões que ofereçam melhores condiç6es de trabalho, o agricultor, muitas vezes, vê-se ante o dilema de usar máquinas ou não poder realizar as diversas operações agrícolas, face a indisponibilidade ou deficiência de mão-de-obra. O sistema operacional utilizado pela maioria dos agricultores, é baseado na mão-de-obra familiar, onde considerável parte da produção obtida é consumida pela família, sendo a restante comercializada. Processos inadequados de manejo do solo e da cultura, contribuem para o decréscimo da produtividade. Apesar...

Provedor de dados: 14
Autores: MARCHÃO, R. L.; BRASIL, E. M.
ABSTRACT: The increment on plant density in narrow row spacing resulted in a greater absorption of photosynthetic active radiation particularly in tropical environments as in the Cerrado Biome. This review aims to analyze the main factors that affect plant arrangement definition in maize, the changes in plant arrangement recommendation and, the modification in plant traits that favored such changes. The choice of plant arrangement in the field must take into account cultivar, grower objective, input availability, planting date and disponible farmer structure. The association between better crop management and highly productive hybrids favored the increase in plant density and reduction in row spacing. Most of research results showed that grain yield was...

Autores: CAMPOS, I. S.; MEDEIROS, J. A.
O arroz é um dos principais produtos agrícolas do país, sondo cultivado em maior ou menor escala, em todas as Unidades da Federação, onde encontra condições favoráveis de clima e solo. A produtividade média do arroz no Brasil, situa-se em torno de 1.500 kg/ha, colocando-se entre os menores níveis de produtividade alcançados pelos demais países produtores.A inferior qualidade de sementes e o enfraquecimento gradativo do solo devido aos métodos rudimentares de cultivo utilizados na maior parte da lavoura arrozeira acreana, tem feito do arroz uma cultura que apresenta baixos níveis de produtividade. O presente trabalho foi orientado para introdução de tecnologias que não apenas representem novas alternativas em relação ao tradicional, mas, sobretudo o aumento...

十勝地方におけるラッカセイ生産の可能性を模索するため、帯広畜産大学実験圃場でラッカセイ品種「千葉半立」、「ナカテユタカ」、および「おおまさり」の栽培を行った。栽植方法（直播、あるいは移植）、および栽植密度（標準植：5.1 株/ ㎡、あるいは密植：7.7 株/ ㎡）の組合せによる4 試験区を設け、2016 年5 月23 日にそれぞれの品種の栽培を開始した。茎葉の黄変期に収穫を行い、収量構成要素や子実収量の評価を行った。千葉半立とナカテユタカでは、子実収量に対する栽植方法と栽植密度の効果が認められた。両品種とも移植を行った試験区で直播を行った試験区に比べ収量が高かった。これは、移植を行うことで単位面積当たりの稔実粒数が増加することに起因する。また、両品種とも密植を行った試験区で標準植を行った試験区に比べ収量が高かった。千葉半立は半立ち性、ナカテユタカは立性の草型をもつため光競合を起こしにくく、十勝地方で栽培する場合には都府県の慣行法よりも栽植密度を高めることで土地利用効率が高まり、子実収量が改善されると考えられる。おおまさりでは、子実収量に対して栽植方法の効果のみが認められた。移植を行うことで直播を行った場合に比べ総稔実粒数や1000 粒重が高まり、子実収量が増加した。一方、おおまさりでは子実収量に対する栽植密度の効果が認められなかった。おおまさりは伏性の草型を持つため光競合が起こりやすく、十勝地方においても密植条件下では密度障害が生じ増収につながらないと考えられる。千葉半立とナカテユタカでは、移植・密植の処理組合せによる試験区で、おおまさりでは、移植・標準植、および移植・密植の処理組合せによる試験区でそれぞれ最も子実収量が高く、いずれも子実収量の全国平均（180g/...

Autores: Ferreira,André S.; Balbinot Junior,Alvadi A.; Werner,Flávia; Franchini,Júlio C.; Zucareli,Claudemir.
ABSTRACT Most studies that found soybean high phenotypic plasticity under different seeding rates adopted the same fertilization levels used for the recommended seeding rates. Therefore, the interaction between these factors is little known. This study aims to assess the interaction between seeding rate and levels of phosphorus and potassium fertilization on soybean growth, grain yield and contents of protein and oil in the grains. The experiment was carried out under a randomized complete block design, in a split-plot scheme, with six replicates. Four seeding rates (150, 300, 440 and 560 thousand viable seeds ha-1) were used in the plots, and two levels of phosphorus and potassium fertilizer were applied in the subplots to meet the export of 3 and 6 t...

Optimum plant population for maize-bean intercropping system in the Brazilian semi-arid region
Provedor de dados: 63
Autores: Morgado,Luiz Balbino; Willey,Robert William.
Establishment of the ideal number of plant is a crucial point for obtaining maximum profits while cropping different species together. The main objective of the study was to investigate the effect of different plant populations of maize and beans, at two nitrogen levels, on the performance of the component crops. Two maize (20,000 and 40,000 plants ha¹) and three bean (30,000; 60,000 and 90,000 plants ha¹) populations were tested in a randomized complete block design with tree replicates. Grain yields of maize and beans were affected by intercropping and the effect was more detrimental to the legume mainly at the highest maize plant population. The application of nitrogen fertilizer to maize rows mitigated intercropping effect on maize at higher population...

Plant densities and modulation of symbiotic nitrogen fixation in soybean
Provedor de dados: 63
Autores: Luca,Marcos Javier de; Hungría,Mariangela.
Soybean nitrogen (N) demands can be supplied to a large extent via biological nitrogen fixation, but the mechanisms of source/sink regulating photosynthesis/nitrogen fixation in high yielding cultivars and current crop management arrangements need to be investigated. We investigated the modulation of symbiotic nitrogen fixation in soybean [Glycine max (L.) Merrill] at different plant densities. A field trial was performed in southern Brazil with six treatments, including non-inoculated controls without and with N-fertilizer, both at a density of 320,000 plants ha−1, and plants inoculated with Bradyrhizobium elkanii at four densities, ranging from 40,000 to 320,000 plants ha−1. Differences in nodulation, biomass production, N accumulation and partition were...

Provedor de dados: 109
Autores: Moreira-Barros,Lílian; Mittelmann,Andréa; Pedroso,Carlos Eduardo; Bortolini,Fernanda; Veronez,Rodrigo Porto; Ramos-Tavares,Luis Guilherme.
Abstract There is a shortage of information about the ryegrass crop (Lolium multiflorum Lam.), especially regarding the suitable sowing rate. Thus, the present work aimed to determine the most adequate sowing rate for tetraploid ryegrass cultivars. A tetraploid ryegrass population was sown at different densities: 150, 300, 600, 900, 1200, 1500, 1800 seeds/m2. The number of plants per m2, percentage of soil cover, leaf yield and green and dry forage yield were evaluated. The experimental design was randomized blocks with three replications. To observe the behavior of the pasture at different densities for each cut, regression analysis was performed, through which it was possible to verify that the sowing rate has greater influence on the initial cut of the...

Autores: Souza-Schlick, Genivaldo David de; Soratto, Rogério Peres; Zanotto, Maurício Dutra.
Plant population and arrangement should be properly designed to maximize the seed yield of short-height genotypes of castor (Ricinus communis L.) in each cropping season. Experiments were performed in the in the fall-winter cropping season of 2008 and 2009 in Botucatu, State of São Paulo, Brazil, to evaluate the effects of row spacing (0.45, 0.60, 0.75, and 0.90 m) and plant population (25,000, 40,000, 55,000, and 70,000 plants ha-1) on agronomical traits, yield components, seed yield, and oil yield of the genotype FCA-PB. A high plant density caused a reduction in plant survival and increased the first raceme insertion height, particularly in the year with the higher rainfall. The basal stem diameter, number of racemes per plant, and seeds per raceme were...
