Traditional Seed Preservation Method

Amidst the rising awareness of environmental impact, traditional methods of seed storage and protection are gaining popularity. A comprehensive study was conducted to document the diverse traditional seed storage structures employed by farmers, with a profound objective of preserving and promoting these practices for future generations.

The transition towards sustainable practices entails reducing reliance on non-degradable and artificially created materials. Here, the power of indigenous knowledge shines through, with its accessibility, low cost, and accumulated wisdom from human interaction with the environment.

Modern Challenges and Their Impact

However, the modern drive for agricultural development to feed a growing population has inadvertently affected traditional seed storage systems. The outer Himalayan regions, for instance, face increasing exposure to formal seed systems and storage technologies introduced by multinational seed companies, including genetically modified seeds and advanced planting methods.

Additionally, public and private institutions’ plant breeding and multiplication methodologies, regulated and certified, have come with specific recommendations and restrictions. While market-driven seeds boost yields through fossil-fuel-based inputs, they simultaneously erode the invaluable community-based plant breeding practices that are deeply rooted in tradition.

As a result, the traditional seed system’s weakening poses a threat to seed sovereignty and in-situ germplasm conservation, thereby jeopardizing the nutraceutical security of marginalized farmers. Furthermore, traditional crop by-products, serving as fodder for livestock, play a pivotal role in subsistence farming.

The Essence of Traditional Seed Systems

Maintaining a traditional seed system, governed by local farmers, emerges as a crucial aspect of sustainable food production, balanced nutrition, and genetic diversity preservation, especially in marginal environments. It involves active farmer engagement in managing adaptable landraces and encompasses various seed-related activities, from selection to production, storage, and exchanges via gifts, barter, or purchases in nearby markets.

Moreover, the traditional seed system nurtures socio-cultural practices, fortifies the network of marginal farming communities, and upholds ancestral knowledge systems and traditional storage techniques. It resists the diffusion of ex-situ seeds, thereby preserving local socio-cultural values and adapting to minor environmental and weather changes, ensuring soil health, market price control, and minimum production and income security, even under adverse agro-climatic conditions.

Unraveling the Erosion of Knowledge

Over time, various studies have revealed the erosion of socio-economic and cultural knowledge intertwined with the traditional seed system. While the role of traditional seed practices in enhancing genetic diversity and gene flow has been widely reported, the scientific evidence supporting seed selection and storage remains relatively scarce, leading to skepticism among proponents of modern agricultural reforms.

Seed Selection and Exchange Practices

In the traditional seed system, farmers prioritize the quality, longevity, and estimated yield of grains and crop by-products over sheer production volume. They carefully select seeds from solo crop fields to avoid contamination and ensure optimal yields. Seed exchange becomes common when yields decline after continuous cultivation, usually around 7-8 years. Farmers also exchange seeds if they become infected during storage or face scarcity due to drought or high seed prices.

The majority of farmers, over 70%, prefer exchanging seeds within their community or neighboring villages, with almost 80% opting for community-level exchanges or purchases to reduce travel expenses. In cases where crop owners are relatives or friends, they mutually agree to exchange seeds, often returning the same quantity or 20% more immediately after the crop harvest.

During these exchanges, farmers account for additional seeds, about 25%, to compensate for storage losses and calculate wastage during sowing. The exchange of cereal crops primarily involves men or heads of households, while women play a significant role in exchanging vegetable and pulse seeds within the village.

Time-Honored Practices for Seed Storage

Critical crops like paddy, millets, pulses, oilseeds, and vegetables such as squashes, pumpkins, cucumbers, French beans, faba beans, long beans, gourds, okra, brinjal, and tomatoes form the major crops for seed exchange. After selection, farmers leave the desired individual plants in situ until they fully mature or ripen, ensuring optimal seed collection. Throughout this process, farmers employ traditional methods to protect these mother plants from wild animal crop raids, grazing livestock, poachers, and pests without resorting to chemical interventions.

Subsequently, the harvested seeds are sun-dried for a few days and stored in various containers made of wood, bamboo, mud, metal, or plastic, all treated with traditional techniques to safeguard them from insects and pests. This in-house storage significantly contributes to the traditional seed system and enhances the genetic diversity of local landraces.

These methods utilize natural substances and techniques to protect grains from pests and ensure longer storage periods.

1. Storage of Seeds with Lime

In this traditional method, pulses are stored alongside lime powder. Approximately 10 grams of lime per kilogram of grains are dusted, and the mixture is placed in jute gunny bags. The strong aroma of lime repels insects, safeguarding the grains from damage and allowing them to be stored for up to one year.

2. Storage of Grains using Camphor

For short-term storage (up to 3 months), grains can be preserved by placing 1 gram of camphor per 5 kilograms of grains in jute gunny bags. The potent odor of camphor acts as a deterrent to storage pests. After three months, the grains are sun-dried and combined with fresh camphor for subsequent storage.

3. Cow Dung in Vegetable Seed Storage

To store vegetable seeds such as ash gourd, bitter gourd, and bottle gourd, farmers create plate-like round structures from fresh cow dung, known as Varatis. The seeds are inserted into the cow dung and dried under the sun for 2-3 days. Once the seeds adhere to the Baratos, they are stored inside wooden boxes. This method allows seeds to be stored for up to one year and can be directly used as seed balls during planting.

4. Neem Oil in Seed Storage

Neem oil serves as a natural repellent against various insects, including weevils, red flour beetles, long-headed flour beetles, and fig moths. Farmers apply 20 milliliters of neem oil per kilogram of pulses, coating the seeds uniformly to protect them during storage.

5. Ash Treatment in Sorghum

For sorghum seeds, a mixture of ash in a 1:4 ratio is applied. The treated seeds are then packed airtight in jute gunny bags, allowing them to be stored for 6 months without encountering storage pest problems.

6. Neem Leaves against Storage Pests

To combat a wide range of storage pests like pulse beetles and grain borers, farmers use a traditional method of keeping Neem (Azadirachta indica) leaves alongside the stored grains in gunny bags. This practice effectively repels storage pests and enables grains to be stored for up to one year.

7. Red Gram Storage with Common Salt

For short-term preservation (6-8 months), farmers manually mix approximately 200 grams of salt with 1 kilogram of red gram grains. The treated grains are then stored in jute gunny bags, which are stitched to keep insects at bay. This practice has proven effective in protecting red gram grains from pests. In some cases, red gram is also coated with oil for added preservation.

Biological, Minerals, and Other Materials in Traditional Pest Control

As the ill effects of synthetic pesticides continue to escalate, farmers are turning to traditional pest control methods that utilize various biological, mineral, and other natural materials.
