Potassium (K) is one of the most important nutrients limiting yield of common bean in South America. Use of K-efficient crop genotypes along with K fertilizer may be a viable strategy to improve yield and reduce cost of production. A greenhouse experiment was conducted to evaluate K-use efficiency of 10 promising genotypes of common bean (Phaseolus vulgaris L.). The genotypes were grown on an Oxisol at 0 mg K kg-1 (low K) and 200 mg K kg-1 (high K) of soil. Shoot dry weight, grain yield, number of pods, number of grains, 100-grain weight, grain harvest index, and K harvest index were significantly (P < 0.01) affected by level of K as well as genotype, except for the number of pods by genotype. Significant genotypic differences in K-use efficiency were found. On the basis of K-use efficiency (mg grain weight/mg K accumulated in shoot and grain), genotypes were classified as efficient and responsive (ER), efficient and nonresponsive (ENR), nonefficient and responsive (NER), and non-efficient and non-responsive (NENR). Only genotype Diamante Negro was only classified as ER, and genotypes Carioca, Pérola, Rosinha G-2, and Xamego were classified as ENR. Genotypes LM93300166 and LM93300176 were in the group NER, and in the NENR group were genotypes Iraí, Jalo Precoce, and Novo Jalo. From a practical point of view, genotypes which produce high grain yield at a low level of K and respond well to added K are the most desirable because they are able to express their high yield potential in a wide range of K availability.

This trial aimed to evaluate the ingestive behavior, feed intake (DMI) and its relationship with health in Holstein, Gyr and Girolando-F1 (½ Holstein ½ Gyr) cows during the transition period. For that purpose, 34 cows were distributed in three groups according to their breed compositions. Behavior, DMI and health conditions were monitored daily during transition. Feed intake and ingestive behavior were distinct for Holstein, Gyr and Girolando-F1 animals. Holstein cows had higher feed intake than Gyr and Girolando-F1 cows during the whole transition period. Before calving, Girolando-F1 cows had higher intake rate, while Holstein cows ingested more feed per visit at the trough. After calving, Gyr and Girolando-F1 cows visited more often the feed trough, but remained less time and ingested less feed per visit than Holstein cows. Regarding health status, Holstein cows presented higher dystocia risk than Gyr and Girolando-F1 cows. The occurrence of subclinical ketosis and mastitis affected DMI during the transition period. The behavior of visits to the feeder, time spent at the feed trough and DMI per visit to the feed trough were modified by the occurrence of dystocia, retained placenta, subclinical hypocalcaemia, clinical and subclinical ketosis.The intake rate was lower in animals affected by subclinical ketosis four days before the disease onset. Likewise, the occurrence of subclinical hypocalcaemia reduced the total time spend at the feed trough and duration per active visit to the feed trough one day before its occurrence, as well as the intake rate four days before its occurrence. Feed intake and ingestive behavior are different for Holstein, Gyr and Girolando-F1 cows. Subclinical ketosis and mastitis affect DMI of cows during the transition period and the behaviors related to the visits to the feed trough are the most affected by the occurrence of diseases in the transition period.
