Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.

Abstract: The objective of this work was to evaluate the productive performance of soybean crops, in response to the use of seeds from lots with increasing vigor levels. The study was developed during the 2014/2015 and 2015/2016crops. In the first period, 14 treatments were evaluated, consisting of two factors, two genotypes (Syn 1059RR and NK7059RR), and seven seed lots. In the second seven treatments were considered, involving one genotype (Syn 1158RR) and seven seed lots. In both crop years, seed lots had vigor levels of 65, 70, 75, 80, 85, 90 and 95%, as determined by the accelerated aging test. The experiment was performed in a randomized block design, with a factorial scheme and five replications. Plant height, yield components, and grain yield were assessed throughout the culture cycle. The reflex of seed vigor in crop performance depended on the genotype employed. Also, there was an increase in both vegetative and reproductive performances of the crop as a function of seed vigor level. In this sense, every percentage point augmented in the vigor level of the lots resulted in a grain yield expansion of up to 28 kg.ha-1.

Abstract: The aim of this study was to assess the effect of seed treatment at different levels of physiological quality with amino acids on the performance of seeds and plants in the field. The experimental design was a randomized complete block design with four replications involving a combination of two factors. Factor A consisted of seed lots of three levels of physiological quality (high, intermediate, and low) and factor B consisted of five doses of a commercial product based on amino acids used in seed treatment.Seeds of different levels of physiological quality were treated with a commercial product (C.P.) at doses of 0, 200, 400, 600, and 800 mL C.P. 100 kg−1 of seeds. After seed treatment, the physiological performance was assessed in the laboratory and then the seeds were sowed in the field aiming at assessing plant performance, yield components, and productivity. Seed treatment with amino acids does not promote the physiological performance of seeds and plants in the field. The productivity of isolated soybean plants from seed lots of a high physiological quality is 15% higher than that of plants from seed lots of a low physiological quality.

Aims: This study aimed to investigate the interaction effect of nitrogen and phosphorus on curd yield and seed production of cauliflower. Study Design: The experiment was laid out at a randomized complete block design with three replications. Place and Duration of Study: Research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, from September 2016 to March 2017. Methodology: The experiment consisted of two factors comprising three levels of nitrogen (270, 220,170 kg ha-1) and three levels of phosphorus (160,130,100 kg ha-1) with control of each nutrient. There were 10 treatment combinations resulting in 30 unit plots where each plot had two rows of 6 plants. Nitrogen and Phosphorus fertilizer were applied as per treatment in the form of Urea and TSP as a top dressing in two equal splits at the time of transplanting and 15 days after transplanting. Results: All the characters related to growth and yield of cauliflower showed significant variation by nitrogen and phosphorus levels at different days after transplanting. Among the different treatment combinations, N270P160 produced maximum plant height (50 cm), leaf area (700 cm2), plant weight (1003 g), curd diameter (18.3 cm), marketable curd weight (601 g) and marketable curd yield (18.5 t) at harvesting compared to control where nitrogen and phosphorus were not used. Moreover, the largest number of leaves (21.3) and curd weight (346 g) was observed by treatment combinations N220P160 at harvesting. For seed production, the highest number of siliqua plant -1 (1461), 1000 seed weight (4 g), seed yield plant-1 (41.1 g) seed yield ha-1 (1.5 t) and germination (97.7%)was also found from N270P160while the maximum number of seeds siliqua-1(20.5) was revealed by N220P160 compared to control treatment. Considering a different point of view, treatment combinations N270P160 can be marked more convenient for cauliflower production than others. Conclusion: It is concluded that the combinations of nitrogen (270 kg ha-1) and phosphorus (160 kg ha-1) would be appropriate for curd yield and seed production of cauliflower.
