Abstract
The present investigation entitled, “Mapping of fruit crop diversity and frost vulnerability using geo spatial tools in Bilaspur district” was carried out at Geoinformatics laboratory, Department of Fruit Science, College of Horticulture and Forestry Neri, Hamirpur (HP) during 2017 to 2019. IRS P6 LISS IV data of November and December were used to monitor and estimate acreage under different fruit crops. The ground truth sites were used as training sites to generate spectral signatures using LISS IV data. The data were analyzed using ArcGIS 10.5.1, MS office & Excel 2007. Total area under mango in district Bilaspur was obtained as 4116.12 ha in 20172018. Out of total mango area i.e 4116.12 ha. Sadar block with 1501.91 ha is the highest mango holding block followed by Jhandutta. Swarghat block in the district Bilaspur has lowest mango area 472.12 ha. In case of citrus, total area was obtained as 1394.91 ha. Out of total citrus area, Ghumarwin block with 512.34 ha is the highest holding block followed by Jhandutta. Sadar block in district Bilaspur has lowest citrus area 205.42 ha. In study area litchi occupy an area of 642.68 ha. Out of total area, Sadar block with 251.42 ha is the highest litchi holding block followed by Ghumarwin. Swarghat is the lowest litchi holding block in study area. The research mapped frost hotspots in the district Bilaspur were identified by establishing the trend of minimum temperature occurrences between the years 2004-2018. Frost is categorized into three categories i.e severe frost (≤1℃), moderate frost (2-3 ℃) and minor frost (4℃) in which the identified probable severe areas are along Berthin, Talai and Talari in Jhandutta block and Brahmpukhar, Namhol, Dehak and Ghagas in Sadar block. The change in the area and production of fruit crop in district Bilaspur from 1997-2018 were analyzed. The study shows that district Bilaspur has undergone a significant change in cropping pattern of fruits. Total area of fruits was increased by 17.08% in case of production it is increased by 110%.
