Abstract:ResumoOs biofertilizantes são produtos orgânicos geralmente obtidos via anaerobiose, estudados, principalmente, como fitoprotetores para a agricultura, mas que podem também incrementar a produção das plantas. Nesse sentido, um experimento de campo foi desenvolvido, no período de maio/2003 a agosto/2004, no município de Remígio-Pb, para avaliar os efeitos de dois biofertilizantes bovinos sobre a massa média, produtividade e a qualidade externa e interna dos frutos do mamoeiro Havaí (Carica papaya L.) cultivar '… Show more
“…The results of the present study are useful to guide researchers in papaya field experiments, since there is not a standard number of plants by plot and number of replications, as can be observed in the following studies: five plants by plot (OLIVEIRA et al, 2014), six plants by plot (REIS et al, 2015), eight plants by plot (DIAS et al, 2011), ten plants by plot (CARDOSO et al, 2014), twelve plants by plot (FERREIRA et al, 2012), and fifteen plants by plot (MESQUITA et al, 2007).…”
ABSTRACT-The aim of this study was to estimate the optimum plot size and number of replications in papaya field experiments. Eleven variables were evaluated in four cultivars of papaya with planting in different seasons between 2011 and 2013 in the north of the Espírito Santo state. Analysis were made from blank test applied to 240 selected for planting season and cultivate plants in commercial fields. The determination of optimum plot size was performed by applying the methodologies of modified maximum curvature and maximum curvature of coefficient of variation. The determination of the number of repetitions was taken from the least significant difference in average 20% and 30%. The optimum plot size proved the same by the two methods studied for most evaluations. The optimum size required differs among cultivars, between variables and between planting seasons, with the largest number of plants was required for the variables number of fruits per plant and yield per plant. We conclude that the optimal number of papaya plants planted in the field is six plants per plot using three replications.

TAMANHO ÓTIMO DE PARCELAS E NÚMERO DE REPETIÇÕES EM EXPERIMENTOS DE CAMPO COM MAMOEIRORESUMO-Objetivou-se neste estudo estimar o tamanho ótimo de parcelas e o número de repetições em mamoeiro cultivado a campo. Avaliaram-se onze variáveis em quatro cultivares de mamoeiro com plantio em diferentes estações do ano entre 2011 e 2013 no norte do Espírito Santo. As análises foram feitas a partir de ensaio em branco aplicado em 240 plantas selecionadas, por época de plantio e por cultivar, em lavouras comerciais. A determinação do tamanho ótimo de parcela foi feita aplicando-se as metodologias de máxima curvatura modificado e máxima curvatura do coeficiente de variação. A determinação do número de repetições foi feita a partir da diferença mínima significativa da média de 20% e 30%. O tamanho ótimo da parcela se mostrou o mesmo pelas duas metodologias estudadas para a maioria das avaliações. O tamanho ótimo requerido difere entre as cultivares, entre as variáveis e entre as épocas de plantio, sendo que o maior número de plantas foi requerido para as variáveis número de frutos por planta e produção por planta. Concluiu-se que o número ótimo de plantas em experimentos de mamoeiro plantados a campo é de seis plantas por parcela com uso de três repetições.

“…Os valores de número de ramos produtivos por planta são inferiores aos 34 ramos obtidos por Cavalcante et al (2007) e semelhantes aos 24,7 ramos verificados por Rodolfo Júnior, Cavalcante e Buriti (2009) em plantas de maracujazeiro amarelo. Segundo Hafle et al (2009), plantas de maracujazeiro com redução no número de ramos produtivos tendem a apresentar decréscimo na produção, pois resulta na diminuição do número de gemas floríferas e, consequentemente, a floração e a produção por planta.…”

“…O biofertilizante bovino é um comporto orgânico bastante utilizado pelos agricultores rurais como uma alternativa viável e econômica, sendo recomendado tanto na adubação, como também no controle de fitomoléstias, reduzindo assim os custos com insumos e defensivos (MESQUITA et al, 2007;SOUZA et al, 2012).…”
(90DAT); and, applied one week before and every 90 days after transplanting (1SAT+90DAT). The electrical conductivity of irrigation water reducing the growth of passion fruit, delaying the timing of flowering of culture. The biofertilizer 1SAT and 1SAT+90DAT, the largest number of applications stimulated the growth of yellow passion fruit plants mitigating the effects of saline irrigation water.
“…In Brazil, the main papaya production country worldwide (Fao, 2011), papaya has been widely produced aiming its consumption as fresh (mainly) or processed fruit into various products, such as chunks and slices for tropical fruit salads, dehydrated slices, cocktails or processed into puree for juices and nectar base, usually frozen; and as canned nectar, mixed drinks and jams, because the puree of papaya fruit is the basis for the remanufacturing of many products. For papaya fruit evaluation, many studies have been conducted in order to understand the postharvest factors that influence papaya quality just as Bron & Jacomino (2006) and Mesquita et al (2007), and others have been developed on the importance of an extra variable and on fruit firmness. Better firmness of papaya fruit delays membrane lipid catabolism thus extending storage life of fresh fruits, what could be improved by fruit treatments before its ripening, likeextra calcium supply, the same manner Mahmud et al (2008) has studied and verified that the infiltration treatment at 2.5% demonstrated the best effect on maintaining fruit firmness.…”

“…Coconut water quality is directly and mainly affected by coconut plant genotype, maturation, plant nutrition, irrigation and climatic conditions, thus it is important monitoring all fruit growth and maturation circle to obtain fruits with high amounts of water, what is very important for coconut water industry. As for papaya fruit processing it is necessary good quality fruits, produced under low costs, as suggested by Mesquita et al (2007), who have evaluated the fruit quality and yield of papaya fertilized with bovine biofertilizers. The results of their study, except for fruit firmness, registered positive effects of the biofertilizers on 'Baixinho de Santa Amália' papaya cultivar in relation to yield, physical and chemical fruit quality.…”
