Activities carried out by the Instituto Colombiano Agropecuario (ICA)-CIAT collaborative project on beans for cold climates in ICA`s regional center in Obonuco and in the dept. of Narino (Colombia) are reported. On the exptl. farm, 6233 materials were evaluated in bush bean trials, of which 103 w...
Although this document is intended to report research on Vertisols, livestock do not respect this boundary as they graze communal land. Hence a general situation of the available feed resources in the highlands is also highlighted which is followed by specific efforts of collaborative partners of...

Grain, fodder and residue management
In 2018, an experiment was run at the IOP farm in Tanzania. Four nutrient management treatments were combined factorial with two tillage options. The results show that the lowest maize yield was obtained under conventional tillage without fertilizer application, and the highest with reduced tilla...

Ensayos Preliminares: Programa de frijol = Preliminary Trials: Bean Program
In tropical Africa, the most common and most extensively evaluated Brachiaria species as cultivated pastures are B. brizantha, B. decumbens, and B. mutica. In recent years, B. dictyoneura cv. Llanero, B. humidicola, and B. platynota have also received increased attention. The first four species p...
Previous economic analysis found alley cropping more profitable than coventional farming. One study that also compared alley farming with small ruminants found it less profitable than alley cropping. The present study shows, on the basis of more recent experimental data, that crop response to mul...

Optimum fodder-mulch allocation of tree foliage under alley farming in southwest Nigeria
Looks into the prospects for the utilization of wheat straw in Ethiopia. Discusses production, utilization and constraints to utilization of wheat straw. Examines the effect of botanical composition and extent of lignification on wheat straw utilization, physical attributes of the straw component...
Reports a concerted interinstitutional attempt to generalize the use of the available draught animal power for the construction of more effective soil surface drainage. The hypothesis is that the relatively high productive potential of the Ethiopian highland vertisols, particularly in high-rainfa...

Improving productivity on highland Vertisols: The oxen-drawn broadbed maker
This chapter reviews relevant Vertisol properties, experimental results and the overall experience of the project on this subject. There are several types of drainage problems in Vertisols whose magnitude may vary from site to site. Drainage improvement is discussed in relation with camber beds, ...
Some of the papers in this report deals with nutrient management; land, soil and water management; grain, fodder and residue management; and technology validation and transfer. The other papers looks into development of coordinated research efforts; distribution and importance of Ethiopian vertis...
