Clay pot irrigation for tomato (Lycopersicon esculentum Mill) production in the north east semiarid region of Ethiopia JARTS
Tesfaye, Tibebu; Sekota Dryland Agricultural Research Center, Sekota, P.O. Box 62, Ethiopia; Tesfaye, Kindie; Haramaya University, Haramaya, P. O. Box 134, Ethiopia; Woldetsadik, Kebede; Haramaya University, Haramaya, P. O. Box 134, Ethiopia.
Water shortage is one of the major constraints for production of horticultural crops in arid and semiarid regions. A field experiment was conducted to determine irrigation water and fertilizer use efficiency, growth and yield of tomato under clay pot irrigation at the experimental site of Sekota Dryland Agricultural Research Center, Lalibela, Ethiopia in 2009/10. The experiment comprised of five treatments including furrow irrigated control and clay pot irrigation with different plant population and fertilization methods, which were arranged in Randomized Complete Block Design with three replications. The highest total and marketable fruit yields were obtained from clay pot irrigation combined with application of nitrogen fertilizer with irrigation water...

Comportamento do arroz de sequeiro em diferentes populações de plantas. Infoteca-e
AZEVEDO, D. M. P. de; MENDES, A. M.; COSTA, N. de L..
Procurou-se verificar a influencia de diferentes espacamentos entre linhas e densidades de semeadura sobre a produtividade da cultivar de arroz Progresso, sob as condicoes do cerrado de Rondonia, em regime de sequeiro e o efeito dos tratamentos sobre os indices de infestacao da Diatraea saccharalis sobre a cultura. Concluiu-se que: Rendimentos de graos foram diretamente proporcionais as densidades de semeadura; Espacamentos nao influenciaram no rendimento da cultura, contudo, observou-se uma tendencia de maiores produtividades com a utilizacao de menores espacamentos; Ocorrencia de D. saccharalis nao foi afetada pelos espacamentos e densidades de semeadura avaliados, no entanto, observou-se uma tendencia de maior incidencia com a utilizacao de menores...

Drought resistance of sugar-cane crop for different levels of water availability in the soil REA
Barbosa,Fernando da S.; Coelho,Rubens D.; Maschio,Rafael; Lima,Carlos J. G. de S.; Silva,Everaldo M. da.
Soil water availability is the main cause of reduced productivity, and the early development period most sensitive to water deficit. This study aimed to evaluate the drought resistance of the varieties of sugar-cane RB867515 and SP81-3250 during the early development using different levels of water deficit on four soil depths. The experiment was conducted at the Department of Biosystems at Escola Superior de Agricultura "Luiz de Queiroz" (ESALQ/USP) in a greenhouse in soil classified as Oxisol, sandy loam texture (Series "Sertãozinho"). Once exhausted the level of available water in the soil, the dry strength of the studied strains are relatively low. Water balance with values less than -13 mm cause a significant decrease in the final population of plants,...

Effects of row spacing and nitrogen topdressing fertilization on the yield of upland rice in a no-tillage system Agronomy
Lacerda, Mábio Chrisley; Nascente, Adriano Stephan.
This study aimed to evaluate the effect of row spacing and nitrogen topdressing fertilization of two materials (genotype 07SEQCL441 CL and cultivar BRS Esmeralda) on the plant height, yield components, grain yield, and quality of an upland rice crop grown in a no-tillage system. Trials were conducted for two growing seasons under field conditions in a 3 x 4 factorial, randomized, complete block design, with four replications. For each material, treatments consisted of the combination of row spacing (0.225, 0.35, and 0.45 m) with nitrogen (N) applied as topdressing (0, 50, 100, and 150 kg ha-1). The lowest row spacing (0.225 m) for genotypes 07SEQCL441 CL and BRS Esmeralda provided a higher number of tillers, number of panicles m-2, and grain yield of rice....

Influence of high planting densities and arrangements on yield and fruit development of Musa AAA Simmonds Acta Agron. (Palmira)
Barrera-Violet,José Luis; Cartagena-Valenzuela,José Régulo; Nanclares-Gómez,Omar Alonso.
Abstract Banana is one of the most abundantly consumed fruits in the world for its contribution to human nutrition, including an important content of potassium. Given the social contribution of this crop in the cropping areas of Colombia, it is necessary to develop agronomic management strategies that contribute to increasing productivity and offering alternatives that regulate the effects of climate seasonality on banana production in the Uraba region of Colombia. For this purpose, different planting densities (2,000, 2,500, 3,000 and 3,500 plants ha-1) and planting arrangements (triangle, rectangle and double furrow), plus a relative control (1,700 plants ha-1 under triangle arrangement), were evaluated in the banana cv. Williams. The experimental design...

O trabalho teve como objetivo conhecer a produtividade, a renda bruta e a renda bruta menos o custo das sementes da beterraba ‘Tall Top Early Wonder’, em resposta ao uso de quatro e cinco fileiras no canteiro e dos espaçamentos de 5,0; 7,5 e 10,0 cm entre plantas. A colheita foi realizada aos 116 dias após a semeadura, quando se avaliaram a altura das plantas, a massa fresca das folhas, o diâmetro e o comprimento das raízes e as massas frescas de raízes comerciais e não- comerciais. A validação do trabalho foi realizada pela determinação das rendas bruta e da rendas bruta menos o custo das sementes obtidas por hectare cultivado. Nenhuma das características avaliadas foi influenciada significativamente pela interação número de fileiras no canteiro e...

Potato crop growth as affected by nitrogen and plant density PAB
OLIVEIRA,CARLOS ALBERTO DA SILVA.
Growth and development variables and dry matter characteristics were studied for cultivar Snowden of potato (Solanum tuberosum L.) to evaluate nitrogen and plant density influence. Disregarding ending of season plant stress, the average number of actives haulms per plant was five and it was not affected by plant spacing. However, seasonal and final number of active haulms per plant were increased at 200 kg/ha of nitrogen. Maximum stem elongation was reached quickly with double density and had the tendency to keep constant at the highest and lowest nitrogen levels after 70 days after planting. Specific stem mass defined as mass per unit stem length was established as an indirect measure of stem thickness and load capacity. Specific leaf mass position in...
