Practicas sencillas para aumentar el rendimiento del cultivo de la yuca (Manihot esculenta Crantz) by Leihner, D.E., Castro Merino, A.

“…The low cassava yields obtained in L.A. at present are the result of a complex of problems: 1) deficient quality of planting material, which results in low sprouting, poor rooting and little initial vigor; 2) inadequate land preparation and planting systems; 3) control systems for pests and diseases are unknown and weed control, untimely; 4) some local var. have a low yield potential. …”

Root adaptations to soils with low fertility and aluminium toxicity by Rao, Idupulapati M., Miles, John W., Beebe, Stephen E., Horst, Walter J.

“…BACKGROUND Plants depend on their root systems to acquire the water and nutrients necessary for their survival in nature, and for their yield and nutritional quality in agriculture. Root systems are complex and a variety of root phenes have been identified as contributors to adaptation to soils with low fertility and aluminium (Al) toxicity. …”

Response of ammonia-oxidizing bacteria and archaea to biochemical quality of organic inputs combined with mineral nitrogen fertilizer in an arable soil by Muema, E.K., Cadisch, Georg, Rohl, C., Vanlauwe, Bernard, Rasche, F.

“…This reduction was attributed to a considerable N stress induced by limited organic N availability in ZM and polyphenol-protein complexes in CC. High abundance of AOA under ZM was attributed to their affinity to ammonium under N limiting conditions. …”

A Fosmid pool-based next generation sequencing approach to haplotype-resolve whole genomes by Suk, Eun-Kyung, Schulz, Sabrina, Mentrup, Birgit, Huebsch, Thomas, Duitama, Jorge, Hoehe, Margret R.

“…This method has a broad range of applications including population and ancestry genetics, the clinical interpretation of mutations in personal genomes, the analysis of cancer genomes and highly complex disease gene regions such as MHC. Moreover, haplotype-resolved genome sequencing allows description and interpretation of the diploid nature of genome biology, for example through the analysis of haploid gene forms and allele-specific phenomena. …”
