Chemical composition and photosynthetically active radiation of forage grasses under irrigation R. Bras. Zootec.
Silva,Edilane Aparecida da; Silva,Wilson Jesus da; Barreto,Antônio Carlos; Oliveira Junior,Antonio Barbosa de; Paes,José Mauro Valente; Ruas,José Reinaldo Mendes; Queiroz,Domingos Sávio.
The present study aimed to estimate the photosynthetically active radiation of tropical forage grasses in ten cutting dates, under irrigation. The following treatments were used: Brachiaria decumbens grass (Brachiaria decumbens cultivar Basilisk), Marandu grass (Brachiaria brizantha cultivar Marandu), Xaraes grass (Brachiaria brizantha, cultivar Xaraes), Mombaça grass (Panicum maximum cultivar Mombaça), Tanzania grass (Panicum maximum, cultivar Tanzania) and Tifton 85 grass (Cynodon spp cultivar Tifton 85). The weather parameters were collected by an automatic meteorological station installed in the location and used for irrigation management. The experiment was arranged in a split-plot completely randomized block design, considering the grasses as plots...

Dry matter yield, thermal sum and base temperatures in irrigated tropical forage plants R. Bras. Zootec.
Silva,Edilane Aparecida da; Silva,Wilson Jesus da; Barreto,Antônio Carlos; Oliveira Junior,Antonio Barbosa de; Paes,José Mauro Valente; Ruas,José Reinaldo Mendes; Queiroz,Domingos Sávio.
The present study aimed to estimate the basal temperature and thermal sum for the following tropical forage plants: Brachiaria decumbens, cultivar Basilisk; Brachiaria brizantha, cultivar Marandu; Brachiaria brizantha, cultivar Xaraes; Panicum maximum, cultivar Mombaça; Panicum maximum, cultivar Tanzania; and Cynodon spp, cultivar Tifton 85, in ten cutting seasons, under irrigation. The climatic data were collected in an automatic weather ministration installed in the experimental area and used for irrigation management. The relative development or regression equation method was used to calculate the basal temperature. The estimated basal temperature values were 15.4; 10.5; 14.2; 13.4; 12.4 and 15.1 ºC and the demands were of 2,088.1; 3,542.5; 2,486.5;...
