Estimation of irrigated oats yield using spectral indices
(2019-08-20)
Spectral indices such as normalized difference vegetation index (NDVI) and Falker chlorophyll index (FCI) are valuable tools for estimating crop yield. However, there remains a need to define the best phenological stages ...
Comparison of two non-destructive techniques to determine DM yield in the tropics
(2018-06)
Dry matter yield determines both stocking rate and animal carrying capacity on farms, but to estimate
such indicators, accurate yield measures are required. Some common techniques to estimate biomass in
pastures are ...

ESTIMATE OF THE GRAIN YIELD OF OATS CULTIVATED UNDER IRRIGATION LEVELS USING CHLOROPHYLL METER
(Faema-fac Educacao & Meio Ambiente, 2018-07-01)
The use of indirect measures of vegetation in agriculture, associated with models, is an efficient way of estimating crop productivity. The objective of this study was to verify the accuracy of models to estimate the yield ...

Los objetivos de este trabajo son:
• Desarrollar miniOCR, una aplicación capaz de reconocer dígitos aislados dibujados a mano en pantalla por el usuario a través del mouse. Utilizará una red neuronal convencional ...
Efeito da densidade de semeadura na produção do amendoim
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-10-01)
In this work, the effects of sowing densities on peanut (Arachis hypogaea L.) crop, cv. Tatu were studied. Three experiments were carried out under field conditions on a soil classified as ''Latosol Roxo'', in the Municipality ...

Mombaça grass yield as a function of nitrogen fertilization based on the use of the chlorophyll meterProdutividade do capim mombaça em função da adubação nitrogenada baseada no uso do clorofilômetro
(2021-01-01)
The objective of this study was to evaluate the yield and agronomic efficiency of mombaça grass achieved with the management of nitrogen fertilization, based on the nitrogen sufficiency index (NSI) calculated using ...
Chlorophyll meter-based leaf nitrogen status to manage nitrogen in tropical potato production
(2021-01-01)
Potato (Solanum tuberosum L.) is a N intensive crop, and meeting its requirements with N fertilization is the primary practice to improve N recovery and achieve suitable tuber yield. A 3-site-year (SY) study was conducted ...
