It All Starts with a Seed
Agriculture is one of the most fascinating subjects in the world . Crop agriculture began more than 10,000 years ago . From the beginning of crop husbandry to our time, seeds have been the key ingredient in the establishment, expansion, diversification and improvement of crop production. Seeds are, first of all, a most efficient and effective means of crop propagation. The seed has always been a key factor in agricultural production. Modern crop production and the science of agricultural also confirms that without seed quality we won’t have a successful agricultural production. Seed is the vital input in crop production because through seed only the investment made on other inputs like pesticide, fertilizer, irrigation and crop maintenance can be realized. The seed required for raising the crop is quite small and its cost is also less compare to other inputs, but the greater income farmer gets depends upon the quality of the small quantity of seed he uses .
Characteristics of good seed : Seed must be true to its type i.e. genetically pure, free from admixtures and should belong to the proper variety or strain of the crop and their duration should be according to agroclimate and cropping system of the locality. It should be free from seed borne diseases and pest infection. It should be clean; free from weed seeds or any inert materials. It should be in whole and not broken or damaged. It should be as fresh as possible or of the proper age. It should contain optimum amount of moisture (8-12 %). It should have high germination percentage (more than 80 %).
Major seed quality characters :
1. Physical Quality: It is the cleanliness of seed from other seeds, debris, inert matter, diseased seed and insect damaged seed. The seed with physical quality should have uniform size, weight, and colour and should be free from stones, debris, and dust, leafs, twigs, stems, flowers, fruit well without other crop seeds and inert material. It also should be devoid of shriveled, diseased mottled, moulded, discoloured, damaged and empty seeds. The seed should be easily identifiable as a species of specific category of specific species. Lack of this quality character will indirectly influence the field establishment and planting value of seed.
2. Genetic purity: It is the true to type nature of the seed, the seedling / plant / tree from the seed should resemble its mother in all aspects. This quality character is important for achieving the desired goal of raising the crop either yield or for resistance or for desired quality factors. .
3. Physiological Quality: It is the actual expression of seed in further generation / multiplication. Physiological quality characters of seed comprises of seed germination and seed vigour. The liveliness of a seed is known as viability. The extent of liveliness for production of good seedling or the ability of seed for production of seedling with normal root and shoot under favorable condition is known as germinability.
4. Seed Health – Health status of seed is nothing but the absence of insect infestation and fungal infection, in or on the seed. Seed should not be infected with fungi or infested with insect pests as these will reduce the physiological quality of the seed and also the physical quality of the seed in long term storage. The health status of seed also includes the deterioration status of seed which also expressed through low vigour status of seed.
Thus seedling is the most essential and crucial input for crop production, It should be completely treated with pesticide /fungicide to protect seed against pests and fungi . HPM’ Chemical & Ferilizers Ltd. offers many seed treatment products like DEVSENA, TAMMA , STUFF and many more. These products applied to the seed can prevent or reduce the harmful attacks of many pathogens. HPM not only gives the seed treatment agrochemicals, also effectively associated with education drives with regards to spreading awareness about better seed quality, enhanced and better farming practices. HPM offers outright counsel and workshops to farmers on how and when to utilize all these agrochemicals.
