The response of mukhi kachu (Colocasia esculenta L.) cultivars (Bilashi and local variety) to inorganic (Urea 140 kg ha-1, TSP = 95 kg ha-1, MP= 145 kg ha-1 and Urea 150 kg ha-1, TSP= 100 kg ha-1, MP= 150 kg ha-1) and organic (Cowdung 5,000 kg ha-1, Mustard oil cake 100 kg ha-1 and Poultry dropping 8000 kg ha-1) fertilizers was determined at the farm of Patuakhali Science and Technology University, Bangladesh. Different levels of organic and inorganic fertilizers showed significant effect on number of cormels, dry weight of cormels and yield of the crop. Organic fertilizers produced significantly higher yields of mukhi kachu over the inorganic fertilizers. The variety Bilashi produced the highest yield (25.66 t ha-1) with the application of mustard oil cake.

The objective of this study was to evaluate the effect of water deficit on thegrowth of common bean cultivated in medium and clayey soil. Two experiments were developed in factorial scheme of 2 x 4 with tension for the determination of field capacity on two levels and soil water deficit on four levels in a completelyrandomized design with three replicates for each soil. Growth analyzes were performed in two phenological stage of crop and the data were submitted to an analysis of variance (p ≤ 0.05). When significant, the F Test (p ≤ 0.05) was used for the qualitative factor and regression analysis for the quantitative factor. The water content in the soil of 40 and 60% of available water exertednegative effects on leaf water potential, leaf area and total dry matter of thecommon bean, independent of voltage adopted in determining the field capacity.

Plot Design

The use of cultivars with a higher yield potential and the adoption of new technology have achieved high grain yields in common bean, which probably changed the demand for nutrients in this crop. However, there is almost no information about the periods of the cycle in which nutrients are most demanded at which quantities by the main cultivars. The objective of this study was to evaluate the macronutrient extraction and exportation by the common bean cultivars Pérola and IAC Alvorada, under different levels of NPK fertilization, on a dystroferric Red Nitosol, in Botucatu, São Paulo State, Brazil. The experiment was arranged in a randomized complete block (split plot) design with four replications. The plots consisted of six treatments based on a 2 x 3 factorial model, represented by two cultivars and three NPK levels (PD0 - 'Pérola' without fertilization, PD1 - 'Pérola' with 50 % of recommended fertilization, PD2 - 'Pérola' with 100 % of recommended fertilization, AD0 - 'IAC Alvorada' without fertilization, AD1 - 'IAC Alvorada' with 50 % of recommended fertilization, and AD2 - 'IAC Alvorada' with 100 % of recommended fertilization) and subplots sampled seven times during the cycle. At higher levels of NPK fertilization, the grain yield and macronutrient extraction and exportation of both cultivars were higher, but without statistical differences. Macronutrient absorption was higher in the treatments with 100 % of recommended NPK fertilization (average amounts per hectare: 140 kg N, 16.5 kg P, 120 kg K, 69 kg Ca, 17.9 kg Mg, and 16.3 kg S). Regardless of the treatment, the demand for N, P, K, Ca, and Mg was highest from 45 to 55 days after emergence (DAE), i.e., in the R7 stage (pod formation), while the highest S absorption rates were concentrated between 55 and 65 DAE. More than 70 % of P, between 58 and 69 % of N, 40 and 52 % of S, 40 and 48 % of K, and 35 and 45 % of Mg absorbed during the cycle was exported with grains, whereas less than 15 % of Ca was exported.

AbstractPhaseolus vulgaris (L.), commonly known as bean or common bean, is considered a promiscuous legume host since it forms nodules with diverse rhizobial species and symbiovars. Most of the common bean nodulating rhizobia are mainly affiliated to the genus Rhizobium, though strains belonging to Ensifer, Pararhizobium, Mesorhizobium, Bradyrhizobium, and Burkholderia have also been reported. This is the first report on the characterization of bean-nodulating rhizobia at the species and symbiovar level in Greece. The goals of this research were to isolate and characterize rhizobia nodulating local common bean genotypes grown in five different edaphoclimatic regions of Greece with no rhizobial inoculation history. The genetic diversity of the rhizobial isolates was assessed by BOX-PCR and the phylogenetic affiliation was assessed by multilocus sequence analysis (MLSA) of housekeeping and symbiosis-related genes. A total of fifty fast-growing rhizobial strains were isolated and representative isolates with distinct BOX-PCR fingerpriniting patterns were subjected to phylogenetic analysis. The strains were closely related to R. anhuiense, R. azibense, R. hidalgonense, R. sophoriradicis, and to a putative new genospecies which is provisionally named as Rhizobium sp. I. Most strains belonged to symbiovar phaseoli carrying the α-, γ-a and γ-b alleles of nodC gene, while some of them belonged to symbiovar gallicum. To the best of our knowledge, it is the first time that strains assigned to R. sophoriradicis and harbored the γ-b allele were found in European soils. All strains were able to re-nodulate their original host, indicating that they are true microsymbionts of common bean.
