The major producing areas of maize are North West, Free State and Mpumalanga, while in Kwazulu-Natal, it is mostly produced for household consumption [ 14 ]. Smallholder farmers prefer to produce white maize for their household consumption and sell it as green maize [ 14 ].…”

“…Most provitamin A carotenoids are available in green, orange and yellow crop tissues [ 11 , 12 ]. Unfortunately, these food sources are usually costly, thus inaccessible to low income communities [ 13 , 14 ]. Therefore, the enhancement of food crops, especially staple crops, through biofortification can lead to the production of food with sufficient carotenoids to combat VAD.…”

Biofortification interventions have the potential to combat malnutrition. This review explored the use of provitamin A-biofortified maize (PVABM) as a vitamin A deficiency (VAD) reduction agricultural-based strategy. Maize has been identified as one of the key staple crops for biofortification to reduce hidden hunger in Africa. Most nutrition interventions have not been successful in reducing hunger because rural communities, who mainly rely on agriculture, have been indirectly excluded. The biofortification intervention proposed here aims to be an inclusive strategy, based on smallholder farming systems. Vitamin A is a micronutrient essential for growth, immune function, reproduction and vision, and its deficiency results in VAD. VAD is estimated to affect more than 250 million children in developing countries. In Africa, especially sub-Saharan Africa, maize is a staple food for rural communities, consumed by most household members. Due to carotenoids, PVABM presents an orange color. This color has been reported to lead to negative perceptions about PVABM varieties. The perceived agronomic traits of this maize by smallholder farmers have not been explored. Adoption and utilization of PVABM varieties relies on both acceptable consumer attributes and agronomic traits, including nutritional value. It is therefore important to assess farmers’ perceptions of and willingness to adopt the varieties, and the potential markets for PVABM maize. It is essential to establish on-farm trials and experiments to evaluate the response of PVABM under different climatic conditions, fertilizer levels and soils, and its overall agronomic potential. For the better integration of PVABM with smallholder farming systems, farmer training and workshops about PVABM should be part of any intervention. A holistic approach would enhance farmers’ knowledge about PVABM varieties and that their benefits out-compete other existing maize varieties.

A B S T R A C TIncreases in room temperature may significantly influence the germination process of several plant species. It can directly interfere directly with physiological, biochemical and other activities, thus altering the maximum seed capacity to activate seedling emergence, as well as the morphological Plants. The objective of this study was to evaluate the effect of temperature on germination of three varieties of corn. It was used three different maize varieties: BRS Assum black, BRS011, and BRS033 Asa Branca. The treatments consisted of three controlled temperature: 20°C and 40°C and 30°C. The variables analyzed were percentage of germination; germination speed index; mean germination time; germination frequency; height change and stem; stem diameter; number of leaves; chlorophyll a, b, overall; fresh and dry stem, leaf and root. The Tukey test was applied at 5%, in the variables when significant. The 30°C temperature range is ideal for germination and early development of corn seedlings. The varieties studied do not differ significantly for dry mass production, except the roots, as well as the biometric variables. There are no differences between varieties in the production of chlorophyll. The temperature of 30 proved that influences the increased production of chlorophyll A and total; stem and leaves dry weight as well as the biometric variables. Keywords: Emergence, seedling, variables, production. R E S U M OAumentos na temperatura ambiente podem influenciar de forma significativa o processo de germinação de diversas espécies vegetais. Podem interferir diretamente em atividades fisiológicas, bioquímicas entre outras, alterando desta forma a máxima capacidade das sementes em ativar a emergência das plântulas, bem como a formação morfológica das plantas. O objetivo desse estudo foi simular em câmaras de crescimento o efeito de diferentes temperaturas na germinação de três cultivares de milho: BRS Assum preto, BRS011 e BRS033 Asa Branca. O experimento foi implantado a partir da utilização dos tratamentos formados por três temperaturas controladas: 20º, 30º e 40ºC. As variáveis analisadas foram percentuais de germinação; índice de velocidade de germinação; tempo médio de
