Understanding the preference of a crop for forms nitrogen (N) is important to ensure efficient use N-sources in agriculture. A study was conducted assess nutrient uptake and dry matter yield six vegetable crops under different ratios ammonium- N (NH4+-N) nitrate-N (NO3–-N) growth medium. Seedlings cabbage, carrot, capsicum, knolkhol, lettuce, tomato, were supplied with five N-treatments (NH4+-N...

Introduction: Adequate biological identification is fundamental for establishing integrated pest management programs and identifying the trophic mutualist relationships that can affect population dynamics. Aphids are main of pepper Capsicum spp. (Solanaceae) crops in Southwestern Colombia, due to their role as vectors viruses. However, aphid species complex, limiting investigations performed ad...

INTRODUCTION In order to conserve the biodiversity of Capsicum species and find genotypes with potential to be utilised commercially, Embrapa Clima Temperado maintains an active germplasm collection (AGC) that requires characterisation, enabling genotype selection and support for breeding programmes. OBJECTIVE The objective of this study was to characterise pepper accessions from the Embrapa ...

ABSTRACT Five Capsicum species were tested for susceptibility to Tomato yellow leaf curl virus (TYLCV) and the mild strain of TYLCV (TYLCV-Mld). TYLCV was able to infect 30 of 55 genotypes of C. annuum, one of six genotypes of C. chinense, one of two genotypes of C. baccatum, and the only genotype of C. frutescens tested but was unable to infect the one genotype of C. pubescens tested. This is ...

Paprika extract is an extract of the fruits of the genus Capsicum. Capsicums are a widely consumed natural foodstuff used as a vegetable, spice or colour. The variety used to manufacture paprika extract for food colouration is Capsicum annuum. Colour extracts have a very low content of capsaicin in contrast to the extracts used as flavouring agents. Paprika extract primarily consists of caroten...
