performance, digestibility of nutrients, microbial nitrogen flow (mnf) and nitrogen efficiency (ne) inearly lactating holstein cows were investigated by diet supplementation with sodium caseinate (cn).multiparous lactating holstein cows (n = 15) with an average body weight of 638 kg and 21 days in milkwere assigned to a completely randomized design (five cows per treatment) and fed a basal diet...

Future rice production problems are related to global warming and water scarcity due climate change. For efficient sustainable production, flood irrigation management high nitrogen applications must be modified. Among the main recommendations include incorporation of fertilizer at critical stages crop, use direct seeding in dry soil instead transplanting method. This manuscript brings together ...

The use of sprinkler irrigation for rice (Oryza sativa L.) crop is a relatively recent practice in Brazil. Therefore, crop soil and fertilization management are still not very well defined. Another problem is the inexistence of specific cultivars adapted to this cropping system. This study aimed to evaluate sprinklerirrigated upland rice cultivars under different soil management practices and n...

Immunocytological studies in this laboratory have suggested that NADH-dependent glutamate synthase (NADH-GOGAT; EC 1.4.1.14) in developing organs of rice (Oryza sativa L. cv. Sasanishiki) is involved in the utilization of glutamine remobilized from senescing organs through the phloem. Because most of the indica cultivars contained less NADH-GOGAT in their sink organs than japonica cultivars, ov...
