  1. SASMIRA CASE STUDIES ON USAGE OF PROMINENT AGROTEXTILE PRODUCTS VIZ., SHADE NETS, GREENHOUSE & MULCH MATS AND THEIR STANDARDS MOT,GOI Workshop, 18.9.08

  2. SASMIRA I. USAGE OF SHADE NETS • Shade nets have special optical properties which improve the utilization of solar radiation by agricultural crops • Their use in Greenhouse promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop Sunflower in natural climate BENEFITS Sunflower under shade net • All season cultivation • Premium quality of produce • Fetches higher market price • Lesser Crop diseases • Easy maintenance of crops • Increased Crop produce • Reduces water requirement

  3. II TYPES OF GREEN HOUSE SASMIRA Low cost – Vegetable Medium cost tunnel – Spices High cost - Floriculture

  4. GREEN HOUSES SASMIRA 2.5 m 3 m 2.0 m 2.0 m 10 m 10 m 5 m 5 m LOW COST Bamboo, Jute Cloth/UV Stabilised Plastic Film, Plastic Wires Natural control on temp.& humidity 100 – 125 MEDIUM COST PVC Pipes, UV Stabilised Plastic Film/ Shade net, Plastic Wires Air circulating fans to control temp. & humidity 450 – 500 HIGH COST Metallic frame, UV Stabilised Plastic Film/ nets, plastic wires Systems to control andregulate temp. & humidity 1500 - 2000 TYPE MATERIAL FEATURES COST (Rs./sq.m)

  5. SASMIRA S.N Crop Type of Green House Increased Yield (%) Increased income (%) 1 Leafy Vegetable Low Cost 50 60 2 Flowers Medium Cost 56 91 3 Tomato Low Cost 159 467 4 Other Vegetables Low Cost Medium Cost 185 290 150 90 ADVANTAGES OF GREEN HOUSE USAGE FOR DIFFERENT CROPS

  6. SASMIRA III. USAGE OF MULCHES • Substrates used in proximity to soil to help conservation of soil moisture and the moderation of soil temperatureirrespective of climatic conditions • Materials used for mulching • Black Plastic Film (BPM) • Nonwoven fabrics BPM in marigold 7-micron plastic in bitter gourd

  7. BENEFITS OF MULCHING SASMIRA • Salinity control • Better fertilizer use • Increase in yield • Weed control • Moisture conservation • Maintenance of soil structure • Soil borne pathogens control ECONOMICS OF MULCHES

  8. SASMIRA Mulching Demonstrations MOT,GOI Workshop, 18.9.08

  9. SASMIRA STANDARDS FOR EVALUATION As such there are no standards for evaluation of a Agrotextile products however the following properties of mulches are evaluated as per available general standards: Sr. N. Test performed Test standard 1. Tensile strength IS 1969 2. UV (With % dosage for UV - A tester (CEN method – high tropical exposure conditions) EuropeanCommittee for standardization) 3. Synthetic shadecloth AS 4174 Standards and Norm required to be developed for Indian Climatic conditions for Agrotextile products MOT,GOI Workshop, 18.9.08

  10. SASMIRA SUMMARISED BENEFITS OF AGROTEXTILE PRODUCTS IN PROTECTED CULTIVATION • Increased productivity (50 - 80 %, depending upon the nature of crop) • Premium quality of produce (increased income by 50 – 60 %) • All season and any region cultivation of crops • Early and even ripening of produce (more harvest cycles per year) • Reduced water consumption (10 – 15 %) • Minimised use of fertilizers and pesticides ( 25 – 30 %) • Prevention of damages due to birds, insects, hail, sunburns, falling off of ripened fruits (100 % protection) MOT,GOI Workshop, 18.9.08
