A study was conducted to investigate the influence of planting methods and tuber weight on growth and yield of local yam cultivars obtained by the minisett technique from white yam (D. rotundata) in Gabon. Trials were carried out in 2014 and 2015 at the experimental ground of the Higher National Institute of Agronomy and Biotechnology, under natural conditions of lightness, temperature and rela...

Interactions between elevated [CO2] and soil water availability have the potential impact on crops and future food security of the world. The study was conducted to investigate vegetative growth response of soybeans under two [CO2] (380 and 800 μmol mol−1) with three soil moisture levels in controlled environment. Slow growth rate and altered crop phenology of soybeans were observed under eleva...

Rotylenchulus reniformis resistant LONREN-1×FM966 breeding lines developed at Auburn University have demonstrated that the nematode resistance is accompanied by severe stunting, limited growth, and low yields. The objectives of this study were to evaluate the effects of applying nematicides to selected LONREN breeding lines on R. reniformis nematode populations, plant stunting, and yield. Four ...

The research aimed to examine: 1) effect of AB Mix nutrient concentration on the growth and yield green mustard, 2) growing media plants mustard greens under a substrate hydroponic system, 3) interaction (cocopiet, husk charcoal sand) system. study used two-factor randomized block design with three replications. Observation variables included: plant height, leaf number , area, fresh weight, roo...

Abstract Background The need for adopting improved rice technologies and practices has become more important in Ethiopia as the national self-sufficiency gap increased. This article examines adoption level factors governing of technology packages using data collected from 594 rice-producing household heads Ethiopia. A multivariate probit (MVP) model involving a system five equations was used to...

The Department of Rural Extension (DNER) in the Ministry of Agriculture and Rural Development (MARD) operates several programs to stimulate maize production through the use of improved technologies in Mozambique’s high-potential regions. Until recently no formal analysis had been carried out to assess the yield performance and profitability of the improved technology packages. In 1996/97 the De...

Corky ringspot disease (CRS) of potato (Solanum tuberosum) is caused by the tobacco rattle virus (TRV), which is vectored by stubby-root nematodes, Paratrichodorus spp. and Trichodorus spp., and is a significant threat to potato quality and production in many areas of the western United States. Between 2002 and 2005, fields with a history of CRS were planted to potato and treated with various c...
