Spectral indices: in-season dry mass and yield relationship of flue-cured tobacco under different planting dates and fertiliser levels
(Hindawi Publishing Corporation, 2013-08-13)
This experiment investigated the relationship between tobacco canopy spectral characteristics and tobacco biomass. A completely randomized design, with plantings on the 15th of September, October, November, and December, ...
Remote sensing applications in tobacco yield estimation and the recommended research in Zimbabwe
(Hindawi Publishing Corporation, 2013-10-28)
Tobacco crop area and yield forecasts are important in stabilizing tobacco prices at the auction floors. Tobacco yield estimation in Zimbabwe is currently based on statistical surveys and ground-based field reports.These ...
Development of tobacco (Nicotiana Tabaccum) yield estimation models using agronomic and remote sensing techniques
Farmers need to monitor crop growth and development and obtain early estimates of final yield. The unavailability of a comprehensive method for estimating crop yield leads to contradicting estimates, subjective national ...
Selection of Optimum Vegetative Indices for the assessment of tobacco float seedlings response to fertilizer management
(ISRN Agronomy, 2012-05-21)
The experiment sought to establish the vegetative indices for assessing tobacco float seedling varieties’ response to different fertilizer rates. A factorial design, with 3 variety × 4 fertilizer management treatments, ...
Assessing the spectral separability of flue cured tobacco varieties established on different planting dates and under varying fertilizer management levels
The NDVI was used to discriminate tobacco variety, assess fertilizer levels, and determine the impact of planting date on separating crops. A split plot design with four planting dates, September, October, November, and ...
