Existing Status of Standards for Agrotech Products sasmira There is a lack of clear Existing Status of Standards for Agrotech Products sasmira There is a lack of clear differentiation of Agrotextile products being used for the same application. The nomenclature of these products did not exist Under Textiles. Barring apart a few products, there did not exist any specification for these products, nationally as well as internationally. There is a lack of guidelines for ideal set – up and processing of Agrotextile products as regards, raw material, machinery, process parameters, quality, cost, etc. The Center of Excellence, Agrotech has addressed these problems.

They can include fishnets, shades, ground covers, thermal screens and crop covers. Common uses for agrotextiles are protecting livestock, maintaining soil humidity and temperature, eliminating the impact of pests and general shading.

sasmira Draft Indian Standard Specification TEXTILES – SHADE NETS FOR AGRICULTURE APPLICATION – SPECIFICATION sasmira Draft Indian Standard Specification TEXTILES – SHADE NETS FOR AGRICULTURE APPLICATION – SPECIFICATION FOREWORD Sunlight is the natural variant which affects the growth of plants. Every plant shows optimum growth and yield under regulated exposure to light and heat. In order to protect fields and greenhouses from the intense solar radiation for healthy plant growth and good harvest, Shade nets with open mesh construction are used to control sunshine and amount of shade required. These shade nets are open mesh structure textiles used to cover the shade houses for regulating the sunlight exposure of plants inside. The mesh size of the nets is variable decides the shading percentage provided. Functionally, these net fabrics allow the air to flow freely. So that the excess heat does not built up under the screen. Also these nets provide benefits of reducing damage to crop from wind, conserve water by reducing evaporation and protection from birds, insects and excessive hail and rains. The selection of shade net depends upon the percentage of shading required for the crop being cultivated. Apart from application horticulture, floriculture, these nets also find usage in nurseries, vermiculture shed, cattle sheds, drying of agro products and also general purpose shading.

Draft Indian Standard Specification sasmira TEXTILES – 100 gsm WOVEN GROUND COVERS FOR HORTICULTURE Draft Indian Standard Specification sasmira TEXTILES – 100 gsm WOVEN GROUND COVERS FOR HORTICULTURE APPLICATION – SPECIFICATION FOREWORD Ground cover fabric is a durable and resilient fabric and is ideal product for creating artificial paving and weed free surfaces around crops in gardens, nurseries, farms and greenhouses. Ground cover is one of the most important Agrotextile products for promoting the growth of crops. It provides weed suppression and ground moisture conservation, whilst allowing roots to breathe and water, air and nutrients to permeate through. This maintains higher soil temperatures and promotes more rapid and even plant growth. It is a woven fabric of UV stabilized polypropylene tape yarns to survive through the effect of continuous exposure to sunlight.
