Shading effects on the yield, quality, and sucrose-metabolizing enzyme activity of sweet corn during filling stage

Two low-light sensitive varieties of sweet corn (Zea mays L.), cultivars Xiantian 5, and Huazhen, were subjected to different shading-intensity treatments during the grain-filling stage in a field experiment in order to clarify physiological mechanisms of lowlight effects on the yield, quality, and sucrose-metabolizing enzyme activity of sweet corn. The results showed that under weak light stress (50% light...

Assessment of water yam (Dioscorea alata L.) landrace varieties for resistance to anthracnose disease

Yam anthracnose disease (YAD), caused by the fungus Colletotrichum gloeosporioides Penz, is the most damaging fungal disease of Dioscorea alata yam worldwide. Local yam varieties, which sustain Côte d'Ivoire’s farmers and other end-users livelihoods, are highly susceptible to this pathogen. Thus, there is a need for developing new yam cultivars to sustain yam production in Côte d'Ivoire. To...

An assessment of tomato production practices among rural farmers in major tomato growing districts in Malawi

Tomato is one of the most commonly grown vegetables in Malawi. However, considerable attention has not been given for its production and marketing aspects among smallholder farmers. Therefore, this study was conducted in six major tomato growing districts in Malawi with the objective of identifying production and marketing practices and constraints affecting tomato productivity. Semi structured questionnaires were...

Multiple solutions for rice farmers’ production constraints in Ethiopia: Cost efficient methods of sheath rot disease management

Rice sheath rot disease is one of the obstacles in Fogera plain of rain-fed rice production system. A cultivar called X-Jigna has been used by small scale farmers based on mono-cropping system for over two decades. This production system contributed to the disease occurrence and adversely impacted the production and productivity. So far, there were no any effective measures taken as research remedies in the rain-fed...

Prospects and constraints faced by smallholder farmers in the cultivation of GM crops: A case study from Northern Ghana

As Ghana prepares to commence commercialization of Genetically Modified (GM) crops, this paper reports findings of a survey that sought the views of smallholder farmers in northern Ghana on the likely prospects and constraints of GM crops cultivation. Multi-stage sampling techniques were employed to sample 360 smallholder farmers across ten districts in northern Ghana with interviews, guided by semi-structured...

Effects of crops residues management systems on crops yields and chemical characteristics of tropical ferruginous soil in Western Burkina Faso

Crop residues' inappropriate management is the main constraint causing the decline in soil fertility and crop yields in Burkina Faso. This study was conducted at the Farako-Bâ Research Station from 2014 to 2019 to assess the effects of crop residue management to improve the sustainability of the cotton-cereal based production systems. The experimental design was complete randomized blocks of Fischer with four...

Role of aromatic plants in the integrated pest management (IPM) of Thrips tabaci Lindeman (Thysanoptera: Thripidae)

Onion thrips, Thrips tabaci Lindeman is a cosmopolitan and polyphagous insect pest. Onion thrips cause direct and indirect damage to onion by feeding and ovipositing on leaves of several horticultural crops. Besides causing direct damage to its host plants, T. tabaci has been known as an asymptomatic transmitter of plant pathogens such as tomato spotted wilt virus (TSWV), iris yellow spot virus (IYSV) and tomato yellow...

Estimation of genotype x environment interaction and stability analysis for protein content on durum wheat (Triticum turgidium Var Durum)

Genotype x environment interaction (GEI) and stability of protein content across locations could be helpful in identifying wheat lines with premium quality. The protein contents of 25 selected durum wheat genotypes tested over six environments in 2017 to evaluate genotype by environment interactions and identify stable genotypes for protein content. Protein content was determined based on Mini-infra Smart T Grain...
