Phosphorus (P) deficiency increased the secretion of phytases from roots of various plant species. The secretory phytases were collected with a dialysis membrane tube for 24 hours from roots of sixteen plant species grown with low or adequate supply of P in nutrient solutions. The activity of not...

Three phases of Rhizobium inoculation trials were carried out as part of a programme to select forage legume germplasm adapted to acid, infertile Oxisols of tropical America. Firstly, a range of tropical forage legumes were evaluated for their response to N fertilization or inoculation with strai...

The seed yields and limitations to seed production for four tropical grass cultivars were defined via a replicated field experiment conducted over three years at the Cerrados Agricultural Research Centre near Brasilia (latitude 15° 36' S; longitude 47° 42' W) in a tropical savanna region. The fou...

The phosphorus (P) content of whole roots and root apices has been reported to increase under aluminum (Al) stress, particularly in Al-sensitive plant varieties. We investigated the impact of Al toxicity on the P content of root apices of two tropical forage cultivars of the Brachiaria genus, gro...

The effects of 3 different stocking rates (1, 2 and 3 cows/ha/yr) on sward structure and the amount and pattern of live leaf defoliation were studied at different hierarchical levels within swards of
signal grass (Brachiaria decumbens
) pastures. Permanently marked plants and tillers were followe...
