Efeito da adubação nitrogenada na produção de mudas de lichieira

Abstract

Nitrogen fertilization in the productionof lychee seedlingsBecause the lack of information on nitrogen application in the production of lychee seedlings in the nursery stage, the present work was carried out in a nursery in the municipality of Urânia-SP (20°11' 25.4'' S and 50° 37' 42.9'' W). The experiment was arranged in a randomized block design with five treatments (five rates of nitrogen in form of urea -45% N): 0, 800, 1600, 2400 and 3200 mg.dm -3 of substrate, with four replications and ten plants for replication. One hundred and four days days after planting, the length of aerial part and roots, number of leaves and content of chlorophyll were evaluated. There was significant effect of N rates only for length of aerial part and chlorophyll content. Nitrogen fertilization of lychee seedlings at the concentration of 2188.33 mg.dm-³ of N in the substrate provided the greatest length of the aerial part. Chlorophyll content in the leaves increased linearly with nitrogen rates.

Nitrogen fertilization in the production of seedlings of Talisia esculenta (A. St. Hil) Radlk

“…Results of studies conducted with various species show responses related to N application for the growth of seedlings in containers (Prado & Vale, 2008;Souza et al, 2009;Leite et al, 2010;Menegazzo et al, 2011;Smarsi et al, 2011;Pereira et al, 2011).…”

Composição química e fitoquímica das farinhas da casca e da semente de lichias (Litchi chinensis Sonn) cultivar 'Bengal'

“…A produção brasileira da lichia ainda não está bem determinada e concentra-se, principalmente, na região Sudeste (SMARSI et al, 2011). Apesar da sua pouca expressão no mercado nacional, a lichia é um fruto não-climatérico, com alto valor comercial e muito apreciado pelos consumidores (XU et al, 2011;GUIMARÃES et al, 2013), o que contribui para a I Departamento de Química, Universidade Federal de Lavras (UFLA), Campus Universitário, CP 3037, 37200-000, Lavras, MG, Brasil.…”

Leaf Area Estimation in Litchi by Means of Allometric Relationships

“…is a plant of the Sapindaceae family, the same of guaraná, pitomba and rambutã, typical of subtropical climate. In Brazil, its introduction occurred in the year 1810 in Rio de Janeiro and, from then, its cultivation expanded to the southeastern region (SMARSI et al, 2011). In early 1970s, the first commercial plantations emerged in the state of São Paulo.…”
