Multiplicación de semillas
La semilla es el insumo básico y más barato para una producción agrícola sostenida. La multiplicación y distribución de semillas de alta calidad de variedades mejoradas es un paso crucial en la producción agrícola de cualquier país.

Seed-based development demands a holistic approach if one aims to have impact for a large number of farmers and across a broad rangeof crops. Seed systems need to be designed to meet multiple goals: increase production, enhance family nutrition, make systems more resilience, and help farmers...
- Abstract, Journal of Biology, 2015 Seed is the most important agricultural input and it is the basic unit for distribution and maintenance of plant population. Improved crop varieties play a critical role in agricultural intensification. In Ethiopia, as in many other countries in sub-Saharan...

What will a farmer who would like to plant a certain rice cultivar for the coming season do when he or she only has a limited amount of seeds? Clonal propagation can be resorted to. Clonal propagation is a method of multiplying rice plants from a single grain, an aged seedling or a rice stubble....

TheProvision of Adequate Tree Seed Portfolio in Ethiopiaproject, led by World Agroforestry (ICRAF), has so far successfully established 14 breeding seed orchards in different parts of the country. The project is supported by the Norwegian International Climate and Forest Initiative represented by...

Abstract, Researchgate, 2017 Early generation seed production may constitute maintenance breeding of improved variety and regular multiplication and supply of smaller quantities of breeder, pre-basic and basic seed. The main purpose of EGS Early generation seed production is to maintain the...

The seeding rate is the weight of the seed planted per unit area of land for any crop. Typical seeding rates range from a few pounds per acre to over 100 lbs/acre. The crop yield is the weight of the produce from a harvested crop. In many cases, the produce is itself a seed that can be replanted....

Abstract, Researchgate, 2015 Field and laboratory studies were conducted in split plot design of three replications to determine effects of four sowing rates (50, 75, 100, 125 kg ha-1) and three row spacing (10, 20, 30 cm) on seed multiplication ratio, seed yield, and seed quality of wheat at...

Seed is the basic and most critical input for sustainable agriculture. The response of all other inputs depends on quality of seeds to a large extent. It is estimated that the direct contribution of quality seed alone to the total production is about 15 – 20% depending upon the crop and it can be...
- Community-based seed multiplication of open-pollinated varieties (OPV) can mitigate against hybrid seed unavailability and its soaring cost thereby increasing access to standard seed for communal areas, especially in drought prone areas.

Abstract, 2018, Euphytica Organic dormancy, the inability to germinate under favorable conditions, is a common problem in many crop species and their wild relatives, leading to more variable emergence, plant density, and growth rates, thus increasing costs, and lowering yield. To overcome these...
