Dry bean is an important legume crop for Latin American people and nitrogen is one of the most yields limiting nutrients for bean crop. A greenhouse experiment was conducted to evaluate nitrogen (N) use efficiency of 20 dry bean genotypes. Genotypes were grown on an Oxisol and two N levels used were without N application (low level) and an application of 400 mg N kg−1 (high level). Shoot dry weight, grain yield and yield components, N concentration and uptake in shoot and grain were significantly affected by N and genotype treatments. Grain yield had a highly significant (P < 0.01) association with shoot dry weight, pod number, grains per pod and 100 grain weight. Among the 20 genotypes tested, Perola, CNFR 7847, CNFR 7865, CNFP 7777 and CNFM 6911 were found to produce reasonably good yield at low N rate as well as responded well to applied N. Whereas, some genotypes like BRS Radiante, CNFP 7624, CNFM 7875, CNFM 7886, CNFC 7813, CNFC 7827, CNFP 7677 and CNFP 7775 produced very good yields at higher N rate but very low yields at lower N rate. Hence, these genotypes are good for farmers using higher technology. Nitrogen concentration and uptake were higher in dry bean grains compared with shoot and 63% of N accumulated at zero N rate and 75% N accumulated at 400 mg N rate were translocated to grain across 20 genotypes. Nitrogen uptake efficiencies were having highly significant (P < 0.01) quadratic relationship with grain yield. This indicates that improving N uptake in dry bean plants can increase grain yield.

In 1995, fourteen maize hybrids and eleven varieties were evaluated over eighteen environments in the northeast of Brazil using a casualized blocks design with three replications. This study aimed to determine the adaptability and stability of these materials, in those environments. Significant differences were observed in varietal performance in relation to environmental conditions. The hybrids performed better than varieties in terms of grain yield averages, especially Pioneer 3041, BR 3123 and AG 510, although not statistically different from the others. Among the hybrids, only Cargill 701 showed adaptability to unfavourable environments while AG 510 gave a good response to environment improvement (by fertilizer addition). The varieties BR 5033, BR 5004 and BR 5028 showed adaptation to unfavourable environments, while BR 473 has also showed a response to environment improvement.. |
