Digital technologies are slowly spreading in agriculture sectors globally. But their adoption is hampered by the digital divide which requires significant public investments, improved policy and incentive frameworks to be bridged. Only after that, digital transformation will take place at scale. DAP is meant to assess the country's readiness for this digital transformation by identifying main bottlenecks, opportunities and risks for digital transformation. DAP will thus guide public investment and policy work to accelerate the scaling up of digital transformation.

The factors influencing the size and shape of exptl. field plots (area of exptl. lot, soil types, trial objective, no. of replicates, and degree of accuracy and homogeneity of the exptl. material) for the execution of field expt. are discussed. The basic principles of the following different methods to determine plot size are described: max. curve method, method of Koch and Rigney, Hatheway's method, and the max. curve method using the multiple linear regression model. Some considerations are presented on the border effect and on plot size in bush and climbing bean trials.

Soil management in the Altillanura of Colombia’s Eastern Plains The strategies used for adequate soil management for the Altillanura (high plains with flat topography) of Colombia’s Eastern Plains are reviewed to establish modern, efficient, and sustainable livestock systems in this region. Advances in technology development within the technical and scientific cooperation agreement signed between Colombia’s Ministry of Agriculture and Rural Development (MADR) and CIAT, as well as those of the Center’s Soils Project and several national institutions co-partners in the agreement.

Efforts to develop cassava technology for the vast areas of acid infertile soils were continued Large-scale germplasm screening in the field was begun in Carimagua for tolerance to low levels of P and acidity and in Quilichao, for tolerance to low levels of P. Various fertilizer trials were used to determine: (a) nutrient absorption and distribution within the plant during a 12-mo.

Research of the physiology section was centered on identifying the characters associated with high root yields and quality in cassava under stress conditions. Plant reaction to water stress was studied, specifically regarding growth and yields of var. M Mex 59 and M Col 22 with a period of artificial rain exclusion. Observations were made throughout the stress period and subsequent recovery. Water stress reduced LAI notably although M Mex 59 maintained a LAI approx. twice that of M Col 22 during the stress period. LAI for both var.
