Logistics and storage of soybean in Brazil

Soybean is one of the most important cultures harvested in the world, and Brazil is ranked the second major producer and the top exporter of this oilseed. Brazil presents good edaphoclimatic conditions for soybean cropping, it has a strong research structure and has capacity to enhance its cropping area, and however, the faulty infrastructure in its own terrain hinders logistic operations for soybean flow and...

Physiological quality of second crop soybean seeds after drying and storage

This work was carried out with the goal of determining the immediate and latent effects of different temperatures of drying air on the physiological quality of soybean seeds produced during the second crop. The seeds, which were collected close to their physiological maturity and had a moisture content of approximately 23% (w.b.), were exposed to different drying temperatures (40, 50, 60, 70, and 80°C) until their...

Response of Chinese cabbage to source and rate of N topdressing application in tropical soil in Brazil

The aim of this study was to evaluate the response of Chinese cabbage (hybrid Deneko) to source and rate of N topdressing application. The experimental design was a randomized complete block, consisting of nine treatments (4x2+1 factorial design), with five replications, that is, four rates of N (54, 108, 162 and 216 kgha-1); two sources of N (urea and ammonium sulphate); and a control (without N topdressing). The...

Response of broccoli to sulphur application at topdressing in the presence or absence of organic compost at planting

The literature has confirmed the efficacy of sulphur (S) when growing Brassicaceae. However, there are no studies with this nutrient on broccoli. Therefore, the aim of this study was to evaluate the response of broccoli (hybrid Avenger) to sulphur rates applied at top dressing in the presence or absence of organic compost at planting. The experimental design was a randomized complete block, with ten treatments (5 x 2...

Nitrogen accumulation and productivity of green corn in function of ways and seasons of top-dressing nitrogen fertilizer application

Nitrogen is one of the nutrients required in large amounts by plants and mostly influences corn yield. With the objective of evaluating the best timing and methods of N fertilizer application in topdressing on corn, this experiment was carried out in Ipameri County, State of Goiás, Brazil, on a Red Yellow Latossol (Ferralsol). The treatments were distributed in a randomized complete block design with four...

Selectivity and efficiency of herbicides in warm season turfgrass varieties

Weed infestations and the few post-emergent control alternatives available are some of the main problems in the management of ornamental and sports lawns. Given the exposed, the study aims to evaluate the selectivity of five herbicides to four grass varieties: Paspalum notatum (bahia grass), Cynodon dactylon (bahama grass- ITG6), Zoysia japonica (japanese lawn grass) and Zoysia japonica (imperial – ITG5), as well...

Effect of humic substances and nitrogen fertilization on yellow passion fruit cultivation in the Brazilian semiarid region

Fruit production of yellow passion fruit (Passiflora edulis Sims. f. flavicarpa Deg.) is affected by several factors, such as climate, soil and agricultural practices, including fertilization and irrigation, which are essential for high crop yield. Thus, an experiment was carried on to evaluate the effect of humic substances and different nitrogen doses supplied through fertigation on fruit production of yellow passion...

Soybean seed treatment with micronutrients, hormones and amino acids on physiological characteristics of plants

The study is aimed at contributing to the research on physiological effects of seed treatment with micronutrients, hormones and amino acids. Two experiments were conducted, first in a greenhouse (partially controlled conditions) and second in the field at Patos de Minas, MG, Brazil. Four seed treatments were arranged in a randomized block design (control; micronutrients Zn, Mn, B, Mo, Ni and Co; hormones: indole butyric...

Fermented milk drink flavored with Murici pulp added of passion fruit bark flour

This study aimed to evaluate the physicochemical parameters, antioxidant activity, color and sensory profile of fermented milk drink with murici and passion fruit bark flour (FCM). Four milk drink formulations were processed: 0% FCM + 5% murici pulp (Treatment 1 - control); 0.5% FCM + 5% murici pulp (Treatment 2); 1.0% FCM + 5% murici pulp (Treatment 3) and 1.5% FCM + 5% murici pulp (Treatment 4). The scanning electron...

Genetic variability and correlation analysis of rice (Oryza sativa L.) inbred lines based on agro-morphological traits

In order to evaluate genetic variability of agro-morphological traits and also determine the correlation between grain yield with its components in rice lines, 17 recombinants inbred lines, their parents and a check variety were grown in research station of Africa rice center in Benin republic during two consecutive years 2013 and 2014. The experiments were laid out in a randomized complete block design with four...

Inorganic solute accumulation in noni (Morinda citrifolia Linn) under salt stress during initial growth

Noni (Morinda citrifolia) is a fruit species which is well adapted to different soil and climate conditions, and may be a good option for farmers in arid and semi-arid regions. To evaluate the tolerance of noni plant in the initial phase to salinity and the accumulation of inorganic solutes in its organs, an experiment was carried out in a greenhouse under hydroponic system. The experimental design was completely...

Phosphorus fractionation in sediments of the ypacarai lake basin

The aim of this paper was to determine the phosphorus fractions in the sediment, at different points of the tributaries, on the lake, and on the Ypacarai lake basin. There was a collection of 23 bottom sediment (SF) samples of 0 to 0.05 m of tributaries of the Ypacarai lake basin and 10 samples from the lake. The sand, silt and clay fractions and textural class were determined; in addition to the P forms, grouped in...
