Effects of biochar produced from different feedstocks and organic fertilizers on soil properties and maize (Zea mays L.) production in the northern part of Rwanda

Discover Agriculture
This study applied biochar derived from different local feedstocks and organic fertilizers (OF) on contrasting acidic soils, Andosol and Nitisol, in order to investigate their effects on selected soil properties and maize growth and yield parameters.

Natural Variation in ZmASB1 Links Tryptophan Metabolism to Root Growth and Drought Tolerance in Maize

Advanced Science, EarlyView.
Natural variation in the maize ZmASB1 promoter regulates tryptophan accumulation, root development, and drought tolerance through a tryptophan–auxin pathway. A 5‐bp InDel alters ZmDOF17 binding and promoter activity, and the favorable allele is enriched during breeding. These findings reveal a cis‐regulatory mechanism linking amino acid metabolism with

RNAi in the Rhizarian Phytopathogen Plasmodiophora brassicae: The Causal Agent of Clubroot Disease in Cruciferous Crops

Advanced Science, EarlyView.
This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.

Zambia Conservation Agriculture Programme (CAP) - a brief update

, 2010
This presentation compares conventional systems and conservation agriculture practices in Zambia. Because of continuous soil disturbance from ploughing with oxen, the top soil is often exposed, which contributes to poor crop emergence, sheet erosion and ...
