Opis:
The paper deals with the trend for Penman- Monteith reference evapotranspiration and climatic water deficit during the first decade of the 21st century in Southern Romania vs the 20th century. For the first half of the year the monthly evapotranspiration values were higher for the first decade of the 21st century vs the means of the 20th century. However, the trend reverses for the second half of the year, but for the whole year the totals were higher for the first decade of the 21st century vs the totals of the 20th century. The yearly temperature means in the first decade of the XXI century showed an increase in the three locations studied, respectively, vs century XX. This warming is responsible to a great extent for the increase in evapotranspiration, and the relationship between evapotranspiration and temperature was highly significant. Water deficit decreased in Constanta and Pitesti, but there was a slight increase in water deficit in the same period in Bucharest-Baneasa. Water deficit increased in the first half of the year and decreased in the second half during the first decade of century XXI in all the three locations investigated vs century XX.

Opis:
In maize plant breeding aimed at producing a hybrid, it is necessary to characterize the parents and hybrids by their agronomic aspects and grain quality so that the processing industry may offer consumers a quality product and also improve its efficiency. This study evaluated the viscoelastic parameters of masa and the chemical and texture properties of tortillas obtained from parent lines (M-54, M55, and CML-242), two single crosses (M54xM55 and M55xM54), and one hybrid (H-70). The morpho- logy of the maize grains and tortillas was analyzed using scanning electron microscopy. The firmness of masa obtained from CML-242 and H-70 maize was higher than that from the other maize genotypes. M-54 tortillas showed the lowest crude fiber content. Otherwise, tortillas obtained from the M55xM54 hard grain had the lowest fat content and extensibility, while H-70 tortillas showed an intermediate breaking point and extensibility. M-54 and M54xM55 tortillas were softer due to their more swollen starch granules. In contrast, rigid tortillas were obtained from CML-242 and H-70. Grain hardness causes different morphology in starch and tortilla of maize genotypes. However, grain hardness did not influence the characteristics of texture in tortillas.

Opis:
The objectives of the research were to: fulfil the preliminary assessment of the sensitivity of the soil, water, atmosphere, and plant and denitrification and decomposition models to variations of climate variables based on the existing soil database; validate the soil, water, atmosphere, and plant and denitrification and decomposition modelled outcomes against measured records for soil temperature and water content. The statistical analyses were conducted by the sensitivity analysis, Nash-Sutcliffe efficiency coefficients and root mean square error using measured and modelled variables during three growing seasons. Results of sensitivity analysis demonstrated that: soil temperatures predicted by the soil, water, atmosphere, and plant model showed a more reliable sensitivity to the variations of input air temperatures; soil water content predicted by the denitrification and decomposition model had a better reliability in the sensitivity to daily precipitation changes. The root mean square errors and Nash-Sutcliffe efficiency coefficients demonstrated that: the soil, water, atmosphere, and plant model had a better efficiency in predicting seasonal dynamics of soil temperatures than the denitrification and decomposition model; and among two studied models, the denitrification and decomposition model showed a better capability in predicting the seasonal dynamics of soil water content.

Opis:
Lowland sawah farmers often puddle to improve soil hydrophysical conditions for rice, but the puddling intensity beyond which no extra yield increases occur is unknown. Agro- nomic effects of six mechanical puddling intensities were assessed in three Nigerian inland-valley bottoms. All puddled plots, irrespec- tive of intensity, produced similar effects at all three locations. At 10 days after transplanting, soil bulk density of all puddled plots re- presented mean decreases relative to control plots of about 22.4, 15.8, and 31.7% at Akaeze, Adani, and Ejeti, respectively. Soil bulk density and moisture content upon saturation were similar during 40-120 days after transplanting. All puddled plots consistently showed taller plants and greater tillering than control plots only at Ejeti. Grain yields were similar among treatments in Akaeze and Adani (mean, 3.71 and 6.42 Mg ha -1 , respectively), but one-pass puddling yielded numerically highest in both locations. At Ejeti, grain yields followed the trend for plant growth, with mean values of 4.36 and 1.81 Mg ha -1 for puddled and control plots, respecti- vely. One-pass puddling may be sufficient for sawah rice grown late particularly in less humid environments.

Opis:
The agronomic management of maize (Zea mays L.) modifies the structure and composition of maize grain and its products like flour, masa, and tortillas. Results have shown that the protein content in flour obtained from maize grains treated with nejayote applied at 150 m3 ha-1 (10.36 g × 100 g-1) and nejayote applied at 75 m3 ha-1 with ovine manure applied at 25 t ha-1 (10.17 g × 100 g-1) was higher than that determined in flour treated with chemical fertilizer (10.05 g × 100 g-1). The flours obtained from maize fertilized without nejayote showed the highest viscosity values and the lowest values were for chemical fertilizer (2816 mPa s) and 75 m3 ha-1 of nejayote with ovine manure applied at 25 t ha-1 (2498 mPa s). The highest elastic and viscous moduli were obtained for masa with the following fertilization regimes: 75 m3 ha-1 of nejayote with 25 t ha-1 of ovine manure, and 150 m3 ha-1 of nejayote with 25 t ha-1 of ovine manure and the lowest values of these parameters were obtained for 75 m3 ha-1 of nejayote with 50 t ha-1of ovine manure. The cohesiveness of masa was the lowest for maize fertilized with nejayote applied at 75 to 150 m3 ha-1, and 50 t ha-1 of ovine manure. The highest concentration of 150 m3 ha-1 for nejayote and the lowest level for ovine manure applied at 25 t ha-1 had a positive influence on the production of nixtamal and tortilla.
