“…Porém, estes valores não foram comparados estaticamente por não terem sido feitas repetições. Este mesmo resultado também foi observado por outros autores na cultura do pepino (SEABRA JR. et al, 2004), da couve-flor (GODOy; CARDOSO, 2005), do brócolis (KANO et al, 2008) …”

“…Os resultados deste experimento são muito semelhantes aos obtidos por Kano et al (2008) que verificaram que a idade das mudas de brócolis (32, 39, 46 e 53) não teve influência na massa e no diâmetro da "cabeça", assim como no número de folhas. Ressalta-se que neste experimento foi utilizada uma variedade botânica da mesma espécie, o mesmo tipo de solo, além de ser conduzido na mesma época do ano.…”

“…Stofella et al (2000), ao avaliarem quatro idades de mudas (20,30, 40 e 50 dias de idade), obtiveram diminuição na produção de brócolis com o aumento da idade da muda. Por outro lado, Kano et al (2008), ao avaliarem quatro idades de mudas (32, 39, 46 e 53 dias após a semeadura) de brócolis, constataram que a idade não influenciou a massa e o diâmetro da "cabeça", bem como o número de folhas por planta.…”

Resumo -A idade de transplante das mudas é um fator de grande importância, pois pode afetar a qualidade e a produtividade das plantas se o volume da célula não for compatível às condições fenológicas das mudas no momento do transplante. O experimento foi conduzido na Fazenda Experimental São Manuel, pertencente à Faculdade de Ciências Agronômicas da UNESP, no período de março a agosto de 2009. O objetivo deste trabalho foi avaliar o efeito da idade das mudas na produção de repolho, híbrido Kenzan. As mudas foram produzidas em bandejas de poliestireno expandido contendo 128 células, sendo que as semeaduras foram realizadas a cada quatro dias compondo os seguintes tratamentos: 37, 41, 45, 49 e 53 dias após a semeadura (DAS). O delineamento experimental foi em blocos ao acaso, com cinco repetições. Foram avaliados, no dia do transplante (11/05/2009), o número de folhas, altura, massa fresca e massa seca da parte aérea, para a caracterização das mudas. Observou-se que a idade das mudas não teve influência nas características avaliadas por ocasião da colheita: número de folhas internas e externas à "cabeça", massa fresca da parte aérea e da "cabeça", massa seca da parte aérea e da "cabeça" e comprimento do "coração".Palavras-chave -Brassica oleracea var. capitata.

The experiment was conducted at São Manuel Experimental farm, Faculdade de Ciências Agronômicas da UNESP, from March to August, 2009. The objective of this study was to evaluate the effect of seedling age on cabbage production, hybrid Kenzan. The seedlings were grown in polystyrene trays containing 128 cells. Seedings were done every four days and contained the following treatments: 37, 41, 45, 49 and 53 days after sowing (DAS). The experimental design was randomized blocks, with five replications. On transplantation's day (11/05/2009), the number of leaves, fresh and dry weight and height, were evaluated to the characterization of seedlings. It was observed that the seedling age had no influence on traits at harvest: number of leaves inside and outside of "head", fresh weight of shoot and "head", dry mass of shoot and "head" and length of "heart".

“…Therefore, the initial differences between seedlings did not remain until the end of the cycle. Kano et al (2008) and Magro et al (2011) reported that after transplanting under favourable conditions, plants may present similar yields when transplanting seedlings with different leaf numbers, fresh and dry matter.…”

The effect of P on different plants and several growth stages are well known to scientists, but there is little information on the effect of P after transplanting the seedling until harvesting. The current study aimed to evaluate the effect of P on tomato seedling and fruit production of Paronset hybrid. Therefore, six treatments (0, 15, 30, 45, 60 and 75mg L -1 P) were evaluated in a randomized complete block design with four replications. Monoammonium phosphate (MAP) was used as P source, in addition to coconut fiber substrate. A linear increase was obtained for leaf area, seedling height, shoot and root fresh matter at 75mg P L -1 . However, yield and fruits characteristics were not affected by increasing P doses on seedlings.Keywords: coconut husk fiber, fertigation, phosphate fertilizer, Solanum lycopersicum, substrate. Abbreviations: AFW_ average fruit weight; CTC_ cation exchange capacity; CV_ coefficient of variation; DAT_ days after transplanting; FD_ diameter of fruit; FH_ height of fruit; MAP_ monoammonium phosphate; M.O_ organic matter; P_ phosphorus; PP_ production per plant; SB_ sum of bases; TNFP_ total number of fruits per plant; V_ base saturation.

“…According to Kano et al (2008), the correct selection of containers and substrates for the production of vegetables can allow a better use of other inputs employed in their production, providing saving in seed costs, ease in cultivation and a reduction of failures in the planting area, resulting in a greater economic efficiency in the cultivation.…”

ABSTRACT:The aim of this study was to evaluate the development of Chinguensai (Brassica pekinensis L.) seedlings, under different formulations of substrates and sizes of containers, in Fortaleza, Ceará.For this, two studies were conducted in factorial design with randomized blocks and four replicates. The first study was conducted in a factorial (31, 18 and 11 cm³) and four evaluation dates (22, 27, 34 and 41 DAS). The fresh and dry weight of the shoot and root systems was evaluated. Both studies showed no interaction between the variables, with differences noted for substrate factors, containers and times in all traits. In the first study, the earthworm compost resulted in the highest yield of fresh and dry seedling weight. In the second study, the container with 31 cm 3 of cell volume showed the highest production of fresh and dry weights. The results showed that the substrate composed solely of earthworm humus and with the use of trays with 31 cm 3 of cell volume provided seedlings of Chinguensai with the optimal production for transplanting 41 DAS.
