Improved forages play an important role in sustaining the livelihoods of small- and medium-scale farmers in the tropics, mainly as a result of their positive effects on livestock production and contribution to economic and environmental sustainability. However, in many regions of the tropics, the...

The yield attributes of 18 accessions of Centrosema, comprising the species, C. macrocarpum, C. brasilianum, Centrosema sp. nov. were compared in two experiments under a cutting regime. Small, grazed swards of various Centrosema spp. sown with Andropogon gayanus in mixture were also studied, with...

The gene pools for breeding cassava (Manihot esculenta Crantz) in Africa currently contain only a fraction of the existing genetic variation found in Latin America where the crop originates. Our research aimed to broaden the genetic base in Africa by introducing Latin American (LA) germplasm. The...

The inheritance of resistance in pigeonpea (Cajanus cajan (L.) Millsp.) to fusarium wilt (Fusarium udum Butler) was studied in crosses between a resistant line ICP 8863 and two susceptible (ICP 2376 and LRG 30) pigeonpea lines. The parents, F1, F2 and backcross populations were screened for resis...

Fusarium root rot (Fusarium solani f.sp. phaseoli) is one of the most important diseases affecting common beans (Phaseolus vulgaris L.). Trials to identify sources of resistance to the pathogen were conducted on 147 bean lines at the National Agricultural Research Laboratories (NARL) at Kawanda i...

Twenty-three accessions of Centrosema pubescens selected for good performance on an infertile, acid soil were tested along with 2 control lines each of C. pubescens and C. acutifolium at 18 locations in tropical America and one location in tropical China. The sites represent 3 major agroecosystem...

A field infestation of Meloidogyne javanica on Desmodium heterocarpon is reported for the first time in the Eastern Plains (Llanos Orientales) of Colombia. An experimental planting of 59 accessions of D. heterocarpon was evaluated for root galls, chlorosis, stunting and dieback caused by M. javan...

Agronomic assessment of 76 accessions of tropical fine stem stylo or "tardio" (Stylosanthes guianensis Sw. var. guianensis) was carried out at the Carimagua Research Station in the eastern plains region of Colombia. Of 27 accessions tested for dry matter yield, CIAT 10136 was the highest yielder ...
