Summary: A quick and sensitive analytical method for estimation of dithiocarbamate residues in spices has been optimized and validated. The method offers high recovery, low limit of quantification and is not interfered by essential oils in spices. It can be used for evaluation of compliance of real samples against the maximum residue limits and safety assessment for human consumption.

Summary: The study aimed to generate preliminary information on pepper types based on morphological characteristics for comparison with known varieties in the spices industry. The different pepper types in Morogoro district showed significant differences in most evaluated traits, which could be used to formulate conservation methods and genetic improvement strategies. Further studies are needed to confirm genetic relatedness and assess internal quality attributes.

Summary: The study analyzed the incorporation of canopy temperature minus air temperature in a simple ecophysiological model across three trials testing different water treatments. The results showed that under certain conditions, this model could predict potato yield more accurately.

Summary: This study used the Ledflex fluorometer to measure the effect of water stress on chlorophyll fluorescence in a fescue field under extreme temperature and light conditions. The results showed a significant decrease in fluorescence level under water stress, which was correlated with surface temperature difference. Airflex fluorometer data obtained from an ultralight plane also supported the findings.

Summary: We conducted active and passive measurements of diurnal cycles of chlorophyll fluorescence on potato crops for 26 days. The results showed that variations in chlorophyll fluorescence were directly influenced by changes in irradiance conditions. Under cloudy sky, chlorophyll fluorescence varied in parallel with photosynthetically active radiation (PAR). On clear sky days, a M-shaped diurnal pattern with a minimum around noon was observed. We derived a proxy of fluorescence yield (FYSIF) from spectral transmittance and demonstrated its close relationship with Fs, outperforming other normalization methods.

Summary: Under the water crisis in agriculture, irrigation methods that save and conserve water are necessary. This study analyzed the effectiveness of two irrigation timing thresholds based on thermal imagery on potato yield and environmental impact. The results showed that irrigation thresholds determined by thermal imagery can reduce production costs and improve yield under furrow irrigation systems.

Summary: This study introduces a nondestructive method to estimate chlorophyll concentrations in potato leaves based on vegetation reflectance. The results were validated with the SPAD chlorophyll meter, showing correlations greater than 90%. This study highlights the potential of vegetation reflectance techniques as indicators for estimating plant biochemical-physiological parameters.
