“…4). The reason accredited for superior RSI and RYI values in these districts for the marketing facility which is highly pronounced in these areas and the district Coimbatore is a most potential area for cotton production [10] farmers are practicing subsistence type of farming, the districts identified as MECZ, for the various crops discussed above has to be continued as MECZ in future also, along with prevailing agro climatic factors, marketing facilities, infrastructural development and remunerative price has to be provided. In order to bring ECZ areas under MECZ for the cotton crop, improved cultivars, advanced cultural practices, better management practices and availability of need based quality inputs at reasonable price must be tried.…”

Cotton is an immensely important crop for the sustainable economy of India and livelihood of the Indian cotton farming community. Identification of potential regions would help in increasing the productivity, ensures better utilization of available resources and avoid wastage of resources in the inefficient zones. Efficient cropping zones of the Cotton crop of Tamil Nadu were keyed out with 30 years data (1985-2015) using Relative Yield Index (RYI) and Relative Spread Index (RSI). The results reveled that in Tamil Nadu, fifteen districts were found for MECZ and three for ECZ. Coimbatore is most essential area for cotton crop. Similarly eight districts are coming under LECZ because RSI were very less compare to RYI. Tiruchirapalli and Ramanathapuram both the district have less RYI and RSI indicating NECZ for cotton crop.

An analytical study was carried over to identify the efficient cropping zone for cultivation of major pulses like Bengalgram, Pigeon pea, Greengram, Blackgram and Horsegram in Tamil Nadu. The data on area, production and productivity of the crops for the period from 1985-86 to 2015-16 (excluding 2014-15) were collected and analysed for their Relative Yield Index (RYI), Relative Spread Index (RSI).Based on the pooled result of the indices for thirty years the efficient cropping zones for the crops were identified. Cuddalore district for Blackgram, Salem, Virudhunagar and Tirunelveli districts for Greengram, Salem, Dharmapuri and Theni districts for Redgram, Coimbatore district for Bengalgram, Salem, Dharmapuri and Dindigul districts for Horsegram were identified as the most efficient cropping zones for the respective pulse crops.

“…Several studies have used RSI and RYI to identify efficient crop zones of various crops in Tamil Nadu, viz. rice, sorghum, black gram, cotton, sugarcane [6,7], pearl millet, red gram, , green gram, chick pea, horse gram [8], and efficient cropping zones for groundnut in Tamil Nadu [9]. But Efficient Cropping Zones of horticultural crops is still an exploration to be taken up by researchers and this paper determines to identify the hotspots of potato and chilli crops along with their zonal shift towards cropping.…”

Potato and Chilli are the most significant horticultural vegetable crops commercially cultivated in both field level and homestead gardening. India is leading producer of chilli and 2nd leading of potato in the world, but inadequate storage and huge unpredictable weather conditions leads to loses. This study was done to analyse trend changes in area, production and productivity over 30 years study period (1985-2015) and also identify Efficient Cropping zones of potato and chillies, at district level for Tamil Nadu during 2000-2015, in order to venture the hotspots of 21st century. Results of trend analysis revealed that potato production was decreasing till early 21st century and thereafter increasing gradually with respect to cropping area and chilli showed reduction in production over the years. Relative Yield Index (RYI) and Relative Spread Index (RSI) were used to figured out potential cropping districts for both crops over Tamil Nadu. Dindigul, Erode and Krishnagiri districts were found to be efficient cropping zone, while Nilgiris is sole district of Most Efficient Cropping Zone (MECZ) for potato. Virudhunagar district has been the Most Efficient Cropping Zone for chilli crop, while Ramanathapuram, Sivagangai, Tirunelveli, and Thoothukkudi districts were identified as potential efficient zone (ECZs) in Tamil Nadu. Hence, this paper attempts to identify the hotspot area and to study the deviation in cultivable land, production and productivity of the crops where farmers are facing most of the problems. The climate change scenarios could influence crop cultivation, and this paper is evident on the changes in efficient cropping zones.
