Book Description
Recently introduced technology-comprising cables used for monitoring grain moisture content (MC) and temperature throughout the entire grain mass during drying offers a means to utilize low-temperature natural air-drying for soybean seed. From an electronic monitor and fan control standpoint, the new technology appears to be very promising for managing drying and storage conditions for soybean seed. The objectives for this study were to simulate conditions typically encountered in on-farm, in-bin drying systems and investigate impact of seed cultivar, temperature, moisture content and duration of storage on seed germination rates and vigor (electrical conductivity). In addition this research addresses the problem of establishing an accurate EMC database, across temperature and relative humidity ranges that are typically encountered during natural air, low-temperature drying of soybean seed. Overall, this study showed that seed viability could be maintained when the MC is at 13% and grain temperature within 20°C to 30°C.

Book Description
"Every year one-third of the food produced worth the US $1 trillion gets spoiled during post-harvest operations. The world population is expected to be to 9.1 billion by the end of 2050 and approximately 70% extra food production is required for maintaining food security. Most of this population rise is expected to be in developing countries which are already facing an issue of food hunger and insecurity.Drying is already an energy extensive process in the industry and in the case of seed grade grain drying, the energy requirement is even higher because of the low drying rate requirement employed worldwide. Microwave drying has evolved in the last two decades and the application of it can be seen in many food industries. However, in the seed industry, the application of novel techniques are not that popular, and the literature doesn’t report sufficient studies on it. In this study, microwave-assisted air drying, fluidized drying, and microwave-assisted fluidized bed of soybean seeds were carried out at the laboratory scale and the viability, vigor and the seed coat quality was studied post drying. In microwave-assisted air drying, thin layer drying at an air temperature (30, 40 and 50°C) and microwave power density (0, 0.5 and 1 W/g) were carried out using face-centered response surface methodology. A 0 W/g microwave power density was studied to highlight the comparison between air and microwave drying. The results showed that drying kinetics was improved by the incorporation of the microwaves with an increase in drying rate, shown by drying rate constant and moisture diffusivity. Also, the drying time was significantly reduced during the microwave-assisted air drying. However, the viability and the vigor of the seeds were damaged during microwave-assisted air drying. The cracking percentage was low, but the fissure percentage was high when the microwave was incorporated. This depicts that the incorporation of microwave in the thin layer drying of soybean is not capable of producing seed grade soybean. Moreover, fluidized bed drying of soybean seeds was carried out at different air temperatures (30, 40 and 50 °C) and air velocity (1, 4 and 7 m/s) with a bed depth of 30 to 32 mm. Air velocity of 1m/s was employed to study the comparison between fixed and fluidized bed. The results showed that fluidization at low velocity improved the drying kinetics with a relatively low negative influence and an increase in air temperature had more influence on drying kinetics. The seeds dried in fluidized bed drying had germination percentage greater than 77% with a reduction in seed vigor. More than 60% of the seeds had a damaged seed coat and the seed coat hardness. In addition to this, microwaves were employed in the fluidized bed drying of soybean seeds and the drying kinetics was further improved as compared with fluidized bed drying. Also, seeds dried in microwave-assisted fluidized bed drying were able to germinate with reduced vigor to the fresh seeds. In microwave fluidized bed drying almost all the seeds had damaged seed coat and the hardness of the seed coat was decreased as compared to fluidized bed drying. The fluidized bed drying technique combined with a microwave can solve the problem of non-homogeneity in bed and low drying rates in the seed drying. However, seed coat damage is a problem which requires attention in adapting these drying techniques as it could lead to spoilage and loss of viability in the seeds during storage"--
A Protocol to Determine Seed Storage Behaviour

Pages : 62
Book Description
This publication provides an approach by which conservationists can determine whether or not long-term seed storage is feasible for a particular species, i.e. whether or not that species shows orthodox seed storage behaviour, and provides advice on the implementation of the protocol, examples of ways in which the results from seed storage studies could be misinterpreted due to confounding factors, as well as several alternative approaches for estimating seed storage behaviour prior to carryng out actual investigations with the seeds. In particular, the latter section introduces the concept of a multicriteria approach for estimating seed storage behaviour.
Seeds Toolkit - Module 2

Book Description
This toolkit – made available in English, French and Spanish – will be promoted as practical guidance to assist in the implementation of the national seed strategies. It will provide a number of practical capacity building tools for essential stages of the seed value chain and targeted primarily at seed sector practitioners who will participate in special training workshops to acquire pertinent technical knowledge and will be expected in return to create a multiplier effect through further follow-up FFS trainings down to the level of seed traders and farmers. In doing so, the toolkit will be used as guidance for conducting country-led workshops and other training activities aimed at strengthening quality seed delivery systems and seed regulatory mechanisms in selected countries. The development of capacity in the production of high quality seeds, the seed replacement rates, true seed cost and realistic seed pricing mechanisms as well as the role of different stakeholders are of critical importance in the process of the formulation of national seed policies, which is one of the core areas of FAO’s delivery at the national level.
