Simple models of the growth and development of legume cover crops in di erent environments may aid the selection of species and genotypes most suitable for particular farming systems. The e ects of temperature and photoperiod on the daily rate of seedling emergence (1/t50%) and the rate of leaf a...

The use of Mucuna spp. in cover crop and green manure technologies is proving to be successful in the tropics and subtropics following intensive efforts in technology transfer to farmers by NGOs (Non‐Governmental Organizations). This includes the transfer of seeds of Mucuna spp. for which the ran...

The base (Tb), optimum (To) and ceiling (Tce) temperature for 50% seed germination and seedling emergence, and the thermal time at sub-optimal temperatures (θ1), were examined in experiments with a range of cowpea genotypes from different habitats and latitudes. There was substantial genotypic va...

Las variedades de arveja (Pisum sativum L.) Botanica INIA, Amarilla INIA, Catrico SS y Lebu Loma 13 fueron cultivadas bajo invernadero en cuatro ambientes compuestos por la combinacion factorial de dos temperaturas medias (15 y 19 C) y dos fotoperiodos constantes (12 y 18 h d-1). Se midio el tiem...
