Adaptability of 5 grass and 13 legume accessions tested in 34 regional agronomic trials throughout the South American humid tropics was assessed by conducting multilocational analysis on seasonal dry matter yield at 12 weeks regrowth. Among legumes, Stylosanthes guianensis CIAT 184 and 136, Desmo...

Various morphological factors affecting the efficiency of production in sorghum (Sorghum vulgare Pers.) were studied at the beginning and the end of the grain filling period. The first part included the morphological description of the plant at the time of anthesis, considering the following para...

Common bean (Phaseolus vulgaris L.) is a vital source of nutrients worldwide. It is one of the most consumed grain legume in Botswana. Fourteen Andean common bean genotypes were evaluated in four environments (two seasons and two diverse agro-ecologies) to determine the effect of genotype and env...

Crop production in sub-Saharan Africa has numerous biotic and abiotic constraints, including nutrient deficiencies. Information on crop response to macronutrients is relatively abundant compared with secondary and micronutrients (SMN). Data from 1339 trial replicates of 280 field trials conducted...

Maize production is constrained by Striga hermonthica in Mali leading to high yield losses. Breeding resistant hybrid maize is a promising alternative for increasing farmers’ income. The objective of this study was to evaluate the response of test crosses to Striga hermonthica and identify high y...

Six weight-classes of white guinea yam (Dioscòrea rotundata Poir.) setts—2–5, 5.01–10, 10.01–20, 20.01–30, 30.01–40, and 40.01–50 g—were presprouted in fresh, moist sawdust in open-air, propagation beds. The 2–5 g and 5.01–10 g classes were described as microsetts. Three natural groups patterned ...

Chloroplast DNA (cp) and nuclear ribosomal DNA (rDNA) variation was investigated in 45 accessions of cultivated and wild Manihot species. Ten independent mutations, 8 point mutations and 2 length mutations were identified, using eight restriction enzymes and 12 heterologous cpDNA probes from mung...
