Abstract
The present investigation was carried out on thermal, humidity, rainfall, moisture index, soil texture
and LGP maps were prepared in the GIS environment using Arc Info 10.1. Agro-ecological zones and sub-zones were delineated by logical combination of soil texture layer in addition to all the spatial input layers (moisture index, LGP and soil layer). Maximum temperature showed decreasing trend (-1.90C/100 year) where as minimum
temperature showed increasing trend (2.170C/100 year) mean air temperature showed increasing trend
(0.6980C/100 year). Morning humidity showed increasing trend at all the seven stations. Similar trend was also observed in evening humidity at all stations except Bawal where it showed decrease trend. Mean relative humidity showed increasing trend at all stations. Rainfall showed increasing trend (2.72mm/100 year) at all the stations in
Haryana except Karnal. Haryana was divided in to 4 climate zones based on moisture index. Eight major and 28 sub agro-ecological zones were delineated by overlapping of climate, LGP and soil digital layers in Haryana. A shift in climatic zones of about 60 km was observed. Crop growing period of 3 to 4 mounts is available in zone- 1(Arid and less than 90 days LGP) and zone-2(Arid and 90-120 days LGP), 4 to 6 months growing period was
available in Zone-3(Semi arid and 120-150 days LGP) and zone-4 (Semi arid and 150-180 days LGP), 6 to 7
months growing period is available zone-5 (Semi arid and 180-210 days LGP) and zone-6(Semi arid and more than 210 days LGP). More than 7 months growing period were available in Zone-7 (Dry sub humid and more than 210 days LGP) and Zone-8(Moist sub humid and more than 210 days LGP). Zone-1 is suitable for mono cropping
systems. Zone-2 is suitable for single long duration crop. Zone-3 to zone-6 was suitable for double cropping
systems. Zone-7 and zone-8 are suitable for multi- cropping systems. Four potential processing areas were
identified for establishment of processing units for processing of farm production based on the availability of raw agricultural products cultivated in surrounding area due to suitability of agro-ecological zones.
