Amaranth species have gained interest in modern agriculture as food, colouring and ornamentals, grown as field crops and garden plants. Their adaptation into production systems relies on exploiting genetic variability. Progenies originated from natur

SUMMARYAcquisition of high-yielding stable cultivars, a major target for breeding, is achievable by repeated trials across different locations and seasons. The hypothesis is whether evaluation of sowing date and season could be used to assess yield s

Soybean cultivation in the acid soils of low latitude Brazilian Savannahs (Cerrados) has become a reality since the 1970's. Soil fertility management and crop breeding have made major contributions to high standard performance of this crop. There are

The soybean is a major crop in the agricultural systems of the Brazilian Cerrados (Savannahs), whose soils are acidic, devoid of nutrients and need to be amended before they are cultivated. However, below the ploughed layer there is a scarcity of nut

The Brazilian tropical adapted soybeans contains, in addition to superior morphological characters, genetic factors for tolerance to cultivation in acidic, mineral-stressed soils. However, the selection process for these hindrances has been empirical

The Brazilian Savannas (Cerrados), a vast area covering one fourth of the country's territory, has acidic soils that are devoid of nutrients and must be amended before cultivation. Mineral disorder on the soya bean crop has been frequent, mainly due

Field techniques to select for aluminium tolerance are very laborious, time consuming and need to be repeated along crop seasons to minimize the effects of uncontrolled environmental factors. The logical alternative is the use of hydroponics experime
