Climate change awareness and adaptation strategies by smallholder farmers in semi-arid areas of Zimbabwe
Published 2024-12-01“…Maize yield remains significantly low, averaging 0.62 t ha−1 among farmers using some forms of soil fertility and water management strategies. To further understand the reason for low maize yields and improve climate change related adaptation strategies, more research is needed to quantify and confirm management practices applied by farmers, such as fertilizer use and rates, water and nutrient management, use of improved varieties as well as socio-economic factors.…”

Factors to affect inbred beet plants while developing material for linear selection
Published 2019-07-01“…In inbred plants, there is no close relationship between pollen viability and seed productivity, because the elimination of germinated male gametes and degeneration of seed embryos may go over the entire period of fertilization starting its progamic phase. The SI plants have more degenerating embryos than self-fertile ones, but seed vessel outgrowth in the seeds with abortive embryos makes them morphologically similar to fertile seeds. …”
