Water Stress Condition

Yield of common bean (Phaseolus vulgaris L.) is highly constrained by water deficit especially when this occurs during the reproductive development. The purpose of the study was to determine the association of the morphophysiological traits with water stress and how this affects grain yield in common beans. A field experiment involving eight common bean genotypes and three water regimes (50 %, 75 %, and 100 % of crop evapotranspiration) was conducted at National Irrigation Research Station, Mazabuka district during the 2012 growing season. A Split plot design with four replications was used; with soil moisture regime (main plot) and the genotypes (subplot). Based on variation in water stress tolerances, 8 test genotypes - Gadra, KE 3, KE 4, ZM 4488, SER 76 SER 180, SER 89 and CAR-ZAR were used. Water stress treatments were imposed at pre-flowering stage and was discontinued after 43 days when the crop was in its late reproductive stage. Significant differences were found among genotypes for Chlorophyll a (Chl a), Chlorophyll b (Chl b), Total Chlorophyll, Relative water content, Grain yield, Number pods per, Seed weight, Seeds per pod and Days to 50 % flowering under the three water stress conditions. The grain yield in normally irrigated condition (2191.3 kg ha-1) was 60 % higher than in high water stress condition (866.2 kg ha-1), while in the low water stress condition (1078.3 kg ha-1), the reduction in grain yield was 50.8 %. There were significant genotype by environment showing that the genotypes behaved differently under the different growing conditions. Results suggested that Gadra, KE 4, ZM 4488, and SER 180 were water stress tolerant while the SER 89, CAR-ZAR, KE 3 and SER 76 were water stress sensitive genotypes. These results suggest that a selection method based on 100 SW, Chl a, Chl b, and NPP can be used in breeding for bean genotypes to water stress.

Filling Stage

An experiment was carried out with common bean (Phaseolus vulgaris, L.) in a Red Yellow Latossol, sandy phase, in order to study the influence of foliar spraying of the Hanway nutrient solution (NPKS) at grain filling stage on: 1) grain yield; 2) the uptake of fertilizer and soil nitrogen by this crop through the root system and 3) the efficiency of utilization of the nitrogen in the foliar spray solution by the grain. The results of this experiment showed that the foliar application of the Hanway solution with ammonium nitrate at the pod filling period caused severe leaf burn and grain yield was inferior to that of the plants which received a soil application of this fertilizer at the same stage. These facts can be attributed to the presence of ammonium nitrate in the concentration used. The composition of final spray was: 114,28 Kg NH4NO3 + 43,11 Kg potassium poliphosphate + 12,44 Kg potassium sulphate per 500 litres. The uptake of nitrogen fertilizer through the root system and the efficiency of its utilization was greater than that through the leaves.

The objective of this work was to evaluate the efficiency of nitrogen fixing inoculum associated with Co + Mo leaf spray on the common bean grain yield and grain nutrients, cv. FT Nobre. Three dosages of the inoculant (0, 200 and 400 g/50 kg seeds), combined with four Co + Mo leaf spray levels (T0=0,0; T1=4.9,49; T2=7.3,73; and T3=9.7,97 g ha-1 of Co and Mo, respectively) were tested. The grain yield with the use of the inoculant (400 g / 5O kg seed-1) associated with the higher level of Co+Mo (T2 and T3) was very similar to the mineral nitrogen condition fertilizer recommended for the bean (70 kg ha-1 of N). With the increased inoculant dosage, an increase of the protein content and of P and Mg in the grain was also observed. The results indicated that the mineral nitrogen source could be replaced by inoculation of the seeds with Rhizobium tropici combined with Co + Mo leaf spray.

ABSTRACT This study evaluated the effect of an organomineral fertilizer enriched with humic substances on soybean grown under water stress. The experiment was performed in a greenhouse using a Red Latosol (Oxisol) with adequate fertility as substrate, in which soybean plants were cultivated with and without water stress. The experimental design was randomized blocks, in a 2 x 5 factorial scheme (two moisture levels and five fertilizer doses: 0, 1, 2, 4 and 8 mL dm-3), totaling 10 treatments, with four replicates. The organomineral fertilizer was applied in the soil 21 days after plant emergence and the water regimes were established one week thereafter. The fertilizer was not able to attenuate the effects of water stress, reducing soybean grain yield by more than 50% compared with plants cultivated under no stress. Fertilizer doses caused positive response on soybean nutrition and grain yield and, under water stress condition, the most efficient dose was 5.4 mL dm-3. There were lower leaf concentrations of nitrogen, phosphorus and potassium and higher concentrations of sulfur in plants under stress. Humic substances favor the absorption of micronutrients.

In Egyptian sugarcane breeding program, a pot experiment was carried out during 2019 season at Agricultural Research Station, Giza Governorate (latitude 26o 33? N and longitude 31o 12? E), Egypt, to evaluate twenty sugarcane clones, compared with the cultivated variety GT.54-9, under three irrigation water levels IWL (100, 80 and 60% of IWL). The traits FW of the shoot and root, root: shoot ratio, LAI, LAR, Chla, Chlb, Chla: Chlb ratio, carotenoids and proline were assessed. From this study clones 17 had height shoot fresh weight under water stress condition, as same as, clones 1, 18 and 19 had great behavior under water stress. In addition to most of sugarcane tested clones were not affected by increase the degree of water stress from 100 to 80% of IWL. The LAI, Chl.a and Chl.b traits showed the high correlation with shoot fresh weight, whereas, proline had strong relationships with root fresh weight under sugarcane drought stress.
