Abstract:

Control of quality standards is very important role in ensuring corn on the market. Corn seed quality standards are determined from the results of classification process applied. So far, evaluation process of classification of corn seeds quality is still done manually which takes a long time and the quality of product is'nt evenly distributed. So, we need a tool to determine corn seeds quality to improve its quality. This study conducted color readings of corn seeds using TCS230 color sensors and sorting diameter of corn seeds using a small, medium, and large diameter sieve machine. The method

The objective of this work was to evaluate the effects of temperature (10, 20, 30, 20/10 and 30/10ºC) and period of storage on electrical conductivity (EC) in four seed lots of corn (Zea mays L.), as well as the mineral composition of the soaking solution. EC test determines indirectly the integrity of seed membrane systems, and is used for the assessment of seed vigor, because this test detects the seed deterioration process since its early phase. The research comprised determinations of water content, germination, accelerated aging (AA), cold (CT) and EC vigor tests, and determinations of Ca

Abstract:

Vigor identification in sweet corn seeds is important for seed germination, crop yield, and quality. In this study, hyperspectral image (HSI) technology integrated with germination tests was applied for feature association analysis and germination performance prediction of sweet corn seeds. In this study, 89 sweet corn seeds (73 for training and the other 16 for testing) were studied and hyperspectral imaging at the spectral range of 400–1000 nm was applied as a nondestructive and accurate technique to identify seed vigor.

The growing demand for high quality soybean [Glycine max (L.) Merrill] seeds requires a precise seed quality control system from the seed industry. One way to accomplish this is by improving vigor testing. Cold test has been traditionally employed for corn seeds. However, it has also been used for other seed crops such as cotton (Gossypium spp.), soybean (Glycine Max), dry bean (Phaseolus vulgaris) and pea (Pisum sativum).

Farmers will choose maize seeds that are fast growing, but will have poor yields on fruit size, resulting in less satisfactory yields. As a result a problem arises that will occur in the absence of determining a number of criteria that can get quality corn seeds. Farmers are not familiar with the use of technology in getting good corn seeds. This requires the use of a system that is able to answer and provide solutions in the selection of corn seeds using a number of criter

Abstract:

The goal of storage is to maintain the characteristics that seeds have immediately after processing; however, when this is over longer periods, storage may cause loss in quality. The aim of this study was to evaluate the effect of treatment with insecticide and fungicide on corn seeds harvested in kernel form and in the ear over the time of storage in two environments for 360 days. The seeds were subjected to the following treatments: T1 - control; T2 - Deltamethrin + Pirimiphos-methyl + Fludioxonil; T3 - Deltamethrin + Pirimiphos-methyl + Fludioxonil + Thiamethoxam; T4 - Thiamethoxam, and T5

In the study grain pile of winter wheat Bezenchukskaya that came from the harvesting was fractionated using laboratory screening with the installation of sieves with hole sizes intervals of 0.2 mm. For selected fractions weight of 1000 grains, the level of injury, laboratory germination of seeds, vitreous grains and gluten content were determined. Processing the results of studies was performed using the methods of mathematical statistics and statistical software package. The studies found that the laboratory germination increases with the weight of 1000 grains and reduction of injury to corn.

Abstract:

The industrial seed treatment combines the application of insecticides, fungicides, nematicides, micronutrients and other products. However, seed submission to the combination of several products can cause phytotoxicity, resulting in reduced viability and vigor, which is directly proportional to the increase in the storage period of the material. Thus, the objective was to determine the vigor of corn seeds and the percentage of germination in substrates when submitted to two types of industrial treatment as a function of storage time. The experimental design was a completely randomized, 2 x 2

A field study was conducted to determine if high seeding rates were economically beneficial for irrigated corn silage production in southern Alberta. On average, 84% of seeds produced a plant, with 12% higher plant establishment in narrow (38 cm) than wide (76 cm) rows. Row spacing did not significantly affect yield, but maximum profitability was attained with a lower seeding rate for narrow rows. Whole-plant dry matter yields and net income were increased by 13% when seeding rates were increased from 64 000 to 74 000 seeds ha-1, but were not significantly affected by seeding rates from 74 000

The dehydration rate was significantly lower in `CNS-711' than `HSII' at all temperatures. In both cultivars, the drying temperature after SMP was critical for seed performance.

The use of seeds with high physiological quality allows rapid growth and establishment of seedlings in the field to be obtained. Therefore, the accuracy of the information obtained during the determination of the physiological quality of seeds is of great importance.

To perform the experiments, we used seeds from five commercial hybrids and/or cultivars of corn and soybean. The ger
