Artificial neural network-(ANN) simulation models have been successfully applied in various fields, including agricultural sciences. This study evaluated the applicability of an artificial network for predicting water distribution uniformity medium-sized sprinklers under varying wind conditions. Using data from 74 field tests, ANN was developed and trained through supervised learning to optimize its predictions. The patterns simulated by closely mirrored observed data, with 50% test set...
O Pará está em destaque na produção de açaí para comercialização nacional e internacional, movimentando um mercado constante expansão. Os modelos microaspersores rotativos variam acordo com a pressão serviço, vazão características aplicação água, como precipitação, dimensão das gotas, número bocais padrão distribuição água. estacionários (“sprays”) não têm movimento rotação, mas funcionam forma similar aos rotativos. Apresentam vantagem permitir sua utilização áreas irregulares, alta baixo...
The use of plant growth-promoting bacteria has proven to be a promising alternative for maize crops. aim this study was evaluate the vegetative growth under different mineral nitrogen doses and inoculation with Azospirillum brasilense. experiment conducted protected cultivation, using randomized block design 20 treatments 4 replications, arranged in 2 x 5 factorial scheme. included A. brasilense control (no inoculation), two water conditions (irrigated suppression), five N doses: 0, 40, 80,...
ABSTRACT Basil is used as spice and for medicinal purposes. Its growth influenced by environmental factors, mainly soil moisture air temperature. Thus, this study was installed to evaluate production of basil under different levels luminosity water replacement. The experimental design completely randomized, with six replicates, arranged in split plot scheme, three the plots (full sun, 50% 70% shading) four replacement subplots (25, 50, 75 100% ETc). We evaluated plant height, stalk diameter,...
Artificial Intelligence (AI) has changed how processes are developed, and decisions made in the agricultural area replacing manual repetitive with automated more efficient ones.
