Time Of Harvest

Trials on the cultivars Canyon and Gallatin 50 in 1978 and Cascade in 1979 were run in North Queensland to examine ways of improving seed quality of snap beans. The trials concentrated on the maturation period, since this is a critical period for the development of seed quality. We found that seed quality was poor when the crop was cut at the stage when the leaves had fallen and all the pods were dry, or if the plants were cut at any stage and allowed to dry on the ground in single rows. This poor seed quality was associated with high pod temperatures during seed maturation. Cutting the crop before leaf fall, at a seed moisture content close to 50% (20-40% of pods dry) and windrowing immediately in 5 or 10 rows to 1 windrow gave low pod temperatures during seed maturation and high seed quality. Seed harvested and threshed directly off the crop was of good quality provided the seed moisture content in the crop had fallen to less than 25%.

Spring Sowing

The present paper evaluates the result of irrigation experiments carried out on snap beans sown in spring and summer and grown with and without irrigation. The experiments were run over the course of 12 years. In the average of 12 years, the yield was 2.8t ha-I for spring sown and 1.9 t ha-I in summer-sown plants without irrigation. The lowest level of profitable production, the 5.5t ha-I was reached twice in the case of spring sowing and only once in the case of summer sowing. Profitable yield production can be ensured only with regular irrigation and thus the yield may be increased by 4-5 times. In four of the twelve years we determined the canopy surface temperature of snap bean stands with and without irrigation. A Raynger II infrared remote thermometer determined the canopy surface temperature every day at 13.00 hours. The canopy temperature can well characterize the water supply of plant stands. This parameter may be used for describing the degree of drought and the water turnover of plant stands with different water supply. The positive values of foliage-air temperature differences (SDD) numerically express the degree of drought and the water supply of the crops. The results indicated that a 1 °C higher SDD value may cause 90-130 kg/ha yield loss.

For a better management of fertigation in protected cultivationof vegetables such as snap beans, it is important to know the nutritional requirements of the plants. Thus, weaimedto characterize the biomass and macronutrients accumulation ofbush snap beansgenotypes. For that, an experiment was carried out in greenhouse, where the genotypesUEL-1 and Alessaweregrown in plastic pots with coarse sandas substrateand fertigation by micro sprinklers. Each ten days, plants were sampled and measured the dry matter and the concentrations of elements such asnitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S)for different plant parts, adjusting their accumulation over timeby the gaussian model.The fresh pods yield (kg m-2) was also evaluated. The accumulation of biomass and macronutrients wasintensified from 20 days after emergence (DAE), reaching maximumvaluesnear 50 DAE. The genotype Alessa presented a higher overall accumulation, while UEL-1 was more productive regarding fresh pods, characterizing suchgenotypeas more efficient for using the macronutrients. For both genotypes, N hadthe highest accumulation, followed by K, Ca, P, S and Mg.

Research on snap bean seed production is essential for this crop to compete against other species that have better production technologies. This study aimed to select a physiological quality evaluation test for snap beans to improve progeny selection strategies. The experiment was conducted in the Seed Analysis Laboratory at the Federal Institute of Goiano, campus Iporá-GO. Seed from thirteen progenies were evaluated for physiological quality from a breeding program conducted by the genetic breeding department of the State University of Goiás, campus Ipameri. Seeds were evaluated for moisture content, thousand-seed weight, biometry (length, width, and thickness), germination, seedling vigor classification, length and seedling dry mass, emergence in the field, and emergence speed index of seedlings in the field. The genetic variability in the evaluated characteristics indicated that genetic breeding can contribute to a better performance in snap bean seed physiological quality. The germination test, vigor classification, emergence, and emergence speed index of seedlings can be used to design strategies for snap bean population selection that produces more productive seeds.
