Melon culture is one of the main sources of income in the generation of employment in the semi-arid regions of Brazil. However, the over-use of fertilizers has provided an organo-mineral fertilization management that reduces environmental impacts with improvement in productivity and fruit quality. It provides the slow release of nutrients and the improvement of the soil's physical, chemical and biological attributes. Current research evaluates the components of production and post-harvest quality of melons fertirrigated with organo-mineral fertilizers. Experiments were conducted between April and June (first harvest) and between October and December (second harvest). Experimental design consisted of randomized blocks with five replications, with treatments in sub-sub-divided splits consisting of two fertirrigation managements (conventional and with urea) in the splits; in the sub-split, four doses of organo-mineral fertilization: 0; 1000; 2000; and 3000 mL ha-1; two agricultural harvests in the sub-sub-split. The Gladial melon hybrid was employed, and the following variables analyzed: fruit diameter and length, pulp thickness, pulp density, number and mean weight of fruits per plant, total productivity and commercial productivity. The second harvest (October to December) had the best productivity rate for melon culture. Organo-mineral fertilization at dose 2,228 mL ha-1, associated with conventional fertirrigation, is recommended in the second semester to increase the fruits' productivity and quality.

A alface é considerada a hortaliça folhosa mais consumida no Brasil, sendo que a escolha e determinação das cultivares a serem plantadas nas diferentes regiões, influência diretamente na produtividade da mesma. Objetivou-se com esse trabalho avaliar o comportamento de cinco cultivares de alface (Brida, Amanda, Cristal, Invicta e Verônica) do grupo solta crespa nas condições de Jataí-GO. O experimento foi instalado em delineamento de blocos casualizados com 4 repetições. As características avaliadas foram: altura e diâmetro de planta, número total de folhas, diâmetro e comprimento do caule, massa fresca total, comercial e do caule e percentual de massa seca. Verificou-se que apenas as características altura de plantas, comprimento do caule, diâmetro do caule, massa fresca do caule e massa fresca comercial apresentaram diferenças estatísticas em relação às cultivares avaliadas. As cultivares que apresentaram os maiores valores de massa fresca comercial foram Brida, Cristal e Verônica. [ABSTRACT FROM AUTHOR]
