Sweetpotato seed exchange systems and knowledge on sweetpotato viral diseases among local farmers in Acholi Sub Region-Northern Uganda
Viral infections greatly limit sweetpotato yields. Good farming practices are critical for effective disease management. 383 Ugandan farmers were surveyed to document symptom incidence, crop-management practices, and buyer preferences. Results showed that 89.27% farmers grow sweet potatoes yearly and 62.76% of these farmers were female. A total of 56.83% farmers obtained vine seeds from their previous gardens, 25.85%...

Water excess in different phenological stages of canola cultivars
The objective of this study was to determine the stage of development with greater sensitivity to water excess and the period of time required to compromise the emergence and grain yield components of canola. The experiments were performed in a greenhouse at the Federal University of Santa Maria and at the Farroupilha Federal Institute, Campus of São Vicente do Sul, RS during the 2015 agricultural year. The...

Effects of biochar on carbon pool, N mineralization, microbial biomass and microbial respiration from mollisol
Biochar incorporation as a soil amendment has been shown to enhance soil quality. However, there has been conflicting reports on its short term effects on C and N mineralization and microbial biomass. An incubation experiment was conducted to determine the effects of three different levels (0.5, 1 and 2%) of biochar on carbon mineralization, soil organic carbon, nitrogen mineralization, microbial biomass and total...

Economics and variety adoption of tuberose: A farm level survey in Bangladesh
qqqQ1`Recently, Bangladesh Government has incorporated flowers in its export policy. Flowers can be a source of earning huge foreign currency if established as a traditional export item. Using cross-sectional data obtained from a survey conducted during 2016/2017, gross margin analysis was used to calculate cost and returns for double (HYV) and single varieties tuberose farmers and multiple regressions for conducting...

Effects of cutting length, time and growing media on the sprouting of dormant semi-hardwood cuttings of pomegranate cv. Wonderful
Scientific confirmation of the traditionally known health benefits of pomegranates caused a tremendous increase in the consumption and production of this highly valuable fruit tree. Reproduction of pomegranate plants with seeds shows great variability in tree vigour and fruit quality. Cuttings is one of the most successful and preferred methods for the propagation of pomegranates. It is easy, quick, economic and most...

Preliminary survey of foliar maize diseases in North Western Ethiopia
In Ethiopia, maize is the staple food and one of the main sources of calories particularly in the major maize producing-regions of the country. Survey was conducted to determine the prevalence, incidence and severity of foliar maize diseases in North Gondar Zone. A total of 150 farmers’ fields were randomly sampled from five districts (Chilga, Gondar zuria, Takussa, Metema and Dembia) in North Gondar Zone of...

Organic matter and maize straw influence on soil moisture in an Oxisol under different tillages
Cultivation system is one of the main parameters inherent to soil water dynamics. Studies indicate that in soil conservation systems, such as no-tillage and crop-livestock integration, soil quality is maintained and even improved due to higher input of organic matter and straw kept on the soil surface. Thereby, the aim of this study was to analyze the influence of the spatial variation of maize straw and organic matter...

Influence of cytoplasmic genetic male sterility in the grain yield of maize hybrids
One of the main barriers to the production of hybrid maize seeds consists of needing detasseling of female parent in order to avoid contamination with unwanted pollen. This activity is a laborious practice, which makes the production more expensive and promotes productive losses. Thus, the use of cytoplasmic genetic male sterility can facilitate the hybridization process, and consequently, the production of hybrid...
