Analysis of colourfastness of fabrics treated with dyes extracted from Roselle calyces

The dyeing potential of roselle (Hibiscus sabdarifa) extract variously extracted by boiling, steeping and ethanol solvent were evaluated with three dye fixatives (potassium aluminum sulphate (alum), tannic acid, and citric acid), to study their effects on cotton (100%), stone silk (60% silk:40% polyester) and polyester (100%) fabrics. Colourfastness to sunlight, washing, perspiration (acid and alkali) and rubbing...

Standardizing germination tests for quinoa seeds

The standard germination tests have been commonly used on commercial grain crops, such as soybean, field beans, rice and maize. However, there are no standard tests for potential new crops; quinoa being one of them. This work is aimed at evaluating the effect of substrate, temperature and counting time in seed germination of quinoa. The following treatments were used in tests with seeds: on blotter paper, between...

Study on termite damage to different species of tree seedlings in the Central Rift Valley of Ethiopia

A high density of termite mounds is common in the Maki-Batu area of the Central Rift Valley of Ethiopia. To determine whether farmers consider termites as one of their problems in growing trees and practices they use to manage termites, short semi-structured questionnaires were distributed to farmers selected randomly. To evaluate the efficacy of some non-chemical control methods, Eucalyptus camaldulensis seedlings of...

Incidence of viruses and virus-like diseases of watermelons and pumpkins in Uganda, a hitherto none-investigated pathosystem

Common impromptu observations between 2010 and 2012 of apparent virus-like disease symptoms in watermelons and pumpkins in Uganda prompted this study. However, there was no recorded evidence of virus infection in these crops anywhere in Uganda or eastern Africa as a region. Thus, 374 and 522 watermelon and pumpkin plants, respectively, growing in 13 fields were surveyed to record virus-like disease symptoms in...
