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

ADVANTAGES OF GREEN HOUSE USAGE FOR DIFFERENT CROPS

III. USAGE OF MULCHES• Substrates used in proximity to soil to help conservation of soil
moisture and the moderation of soil temperature irrespective of climatic conditions
• Materials used for mulching– Black Plastic Film (BPM)– Nonwoven fabrics
BPM in marigold 7-micron plastic in bitter gourd
SASMIRA
BENEFITS OF MULCHING
• Moisture conservation• Maintenance of soil structure• Soil borne pathogens control
ECONOMICS OF MULCHES
• Salinity control• Better fertilizer use• Increase in yield• Weed control

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) European Committee for
standardization)
3. Synthetic shadecloth AS 4174
STANDARDS FOR EVALUATION
Standards and Norm required to be developed for Indian Climatic conditions for Agrotextile products

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)
