No periodo de 1983 a 1985, foi conduzido na regiao do sertao pernambucano do Sao Francisco, no municipio de Petrolina, PE, um trabalho de campo com o proposito de investigar os efeitos de espacamento, densidades populacionais e manejo de solo sobre a producao de dez cultivares de gergelim. Os resultados evidenciaram que o sistema de captacao de agua de chuva "in situ" aumentou significativamente, a produtividade de gergelim em relacao ao plantio no plano nos anos de irregularidades pluviometricas.

Trigo Embrapa 42: nova opcao para os triticultores de Goias e Distrito Federal.

ALBRECHT, J. C.; ANDRADE, J. M. V. de; SOUSA, C. N. A. de; BRAZ, A. J. B. P.; VANDERLEI, J. C..

A nova cultivar Embrapa 42 (Triticum aestivum L.) foi desenvolvida pela Embrapa Cerrados, Planaltina-DF e Embrapa Trigo, Passo Fundo-RS. Originou-se do cruzamento entre as linhagens LAP 689 (Arthur Type*2/7 Cerros//Ter/Bulgaria 88/3/Ciano/Inia) e MS 7936 (Kavkaz/Tanori//Tito sib). Sendo recomendada para plantio no sistema de cultivo irrigado por aspersao, na estacao seca, no estado de Goias e no Distrito Federal, desde 1994. Essa cultivar destaca-se por apresentar alto potencial de rendimento de graos, altura media, ciclo precoce e resistencia ao acamamento. Quanto a qualidade industrial e um trigo de gluten forte e estabilidade alta, que conferem a ela uma classificacao de trigo melhorador. Em relacao ao rendimento de graos, na media de 11 experimentos...

Assis,Gleice Aparecida; Assis,Franscinely Aparecida; Scalco,Myriane Stella; Parolin,Francisco José Toloza; Fidelis,Iraci; Moraes,Jair Campos; Guimarães,Rubens José.

The objective of this work was to evaluate the effect of different drip irrigation regimes and planting densities on the incidence of the leaf miner, Leucoptera coffeella, in arabica coffee plants for one year. The experiment was carried out in 2008, in a complete randomized block design, in a split-plot in time arrangement, with four replicates. The treatments consisted of four drip irrigation regimes - soil water balance, irrigations at 20 and 60 kPa soil tensions, and a nonirrigated treatment -, which were distributed at three plant densities: 2, 500, 5, 000, and 10, 000 plants per hectare. The evaluations were made on a monthly basis between January and December 2008. The highest pest occurrence period was from August to November, a season with low-air...

A three years set of experiment have been conducted during 2010-2012 to develop and test for rice yield improvement and production cost reduction in Southern part of Thailand. This experiment was conducted in rice research center in the first two years and in farmer field for the third year with Split Plot in RCB; rice varieties as main plots and rice seed rate or spacing as sub plots and 4 replications. Results in research center found that for broadcasting rice, Pathum Thani 1 and RD37 which were photoperiod insensitive varieties gave the highest yield when direct broadcasted with 20 kg/rai seed rate whereas photoperiod sensitive varieties such as Chiang Phatthalung and Sangyod Phatthalung showed the highest yield when soak seed broadcasted with 15...

ABSTRACT Brazilian watermelon productivity is not efficient when compared to the largest producer countries, due to abiotic and biotic factors. Some of the difficulties are because of a small number of studies on this crop in Brazil. The aim of this study was to evaluate the effects of plant density and fruit thinning on two commercial watermelon hybrids (Talisman and Youlie), using trials which were carried out in two different seasons (April - July and August - November). The experiment was conducted in Uberlândia-MG and consisted of two managements of fruit position (A-basal and B-distal) and four plant densities (3,000, 4,000, 5,000 and 6,000 plants/ha). In season 1, the distal management was the most productive in relation to all cultivation...

Seedlings compete for nutrients, water and light. The available area for each seedling affects their behavior related to requirements for these resources. This experiment evaluated the influence of five plant densities on the growth of bare root Pinus taeda, L. seedlings in a nursery after outplanting. The analyzed characteristics were: height (H), root collar diameter (D), H/D ratio, and dry matter weight. Higher densities stimulated H growth and the lowest densities increased D average and dry matter weight and lowered the H/D ratio. Seedlings were distributed by H, D and H/D classes. Higher densities had a larger number of seedlings in larger H classes. Larger numbers of seedlings with larger D and lower H/D ratios were found in lower densities. Ten...

Verificou-se o efeito de diferentes espaçamentos com suas respectivas densidades em viveiro de seringueira, na produção de mudas do tipo convencional (raiz nua). Dos resultados obtidos, conclui-se que as melhores opções de espaçamento para viveiro de seringueira, levando-se em consideração uma maior produção de porta-enxertos por unidade de área, foram: 6(0,60m x 0,15m) x 1,20m e 2(0,50m x 0,15m) x 1,0m, com 62715 e 56960 porta-enxertos/ha em condições para receber os dois tipos de enxertia: verde e convencional.

ABSTRACT The aim with this study was to evaluate the effects of single- and twin-row spatial arrangements associated with different doses of fertilization on soybean yield and its components. The experiment was carried out at Federal University of Goiás, Campus of Jataí, in a split-plot randomized block design with 10 treatments and four replicates. Each plot corresponded to a dose of P and K fertilization (0, 50, 100, 200 and 400% of the recommended dose) and the subplots to two types of spatial arrangements: single and twin rows. The yield components evaluated were plant final population, number of pods and seeds per plant, number of seeds per pod, weight of a thousand grains and yield. The increase in fertilization dose, even at doses two and four times...
