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.

Three experiments were carried out in the central area of the state of Veracruz, Mexico, during the Fall-Winter seasons of 1989-90, 1991-92 and 1992-93. The main objective was to determine the effect of the time and type of weeding on the yield of residual moisture growing beans. Twelve treatments, arranged in a CRBD with four replications were evaluated. Treatments consisted in hoeing at different times. In some treatments, hoeing was complemented with hand-weeding. The highest grain yields were obtained when the weeds were eliminated at least in two ocations during the early stages of development of the crop. The yield of these treatments was significantly higher than that obtained with the traditional weeding practice (hoeing at 25 days after emergence).Handweeding after hoeing increased grain yields at high weed densities,but when the weed density was not very high, handweeding after hoeing made no difference. The increase in grain yield obtained when two weeding operations were performed instead of one, was sufficient to cover for the expenses of this additional practice and to generate economic profits.

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.

The present study was conducted at the parish of San Roque, canton Antonio which is before the county of Imbabura. The seed materials used in this study are seeds of frijol varieties such as Paragachi, Canario, and Yunguilla which comes from Santa Catalina (INIAP). The treatments were made up of fréjol varieties (Phaseolus vulgaris L) through the use of the lunar calendar. It uses the design blocks totally at random (DBCA) with six treatments and four repetitions. Their variables were subjected to the variance analysis and it was used to determine the statistical differences of multiple ranges. The Tukey test was also used in this study. The development of the experimental rehearsal were carried out by the following works based on the analysis of the floor, preparation of the floor, subscriber, sowing, fertilization, watering, control of overgrowths, control Phytosanitary, and harvest. To estimate the effects of the treatments, the following data was collected: height from the plant to 30, 60, and 90 days after planting, days of flowering; days of maturation; longitude of sheaths; number of sheaths for plant; number of seeds forsheath; weigh of 100 seeds; grain yield; and economic analysis. According to the interpretation of the results, it was deduced that the biggest plant height was obtained by planting variety of Paragachi. This is done with the use of the lunar calendar. Also, the planting of variety of Yunguilla, using the agricultural lunar calendar, reported bigger number of sheaths for plant and seeds for sheath. The variable days of flowering and days of maturation shows a highly significant difference in the studied treatments. The biggest longitude of sheaths (14,55 cm); weigh of 100 seeds (73,25 g), and yield (3325,00 kg/ha) presented canario variety using lunar calendar. With regards to the economic analysis, all the treatments obtained profitable results. The canario variety stands out using the agricultural lunar calendar with a bigger net profit of $ 3274,14.
