Dynamics of Cropping Pattern in Karimnagar District of Telangana – A Markov Chain Approach

Abstract

The assessment of shift in cropping pattern in several regions is crucial for a much better insight into the agricultural development method. The present study was undertaken to examine the dynamics of cropping pattern in Karimnagar district of Telangana. The data was collected from Directorate of Economics and Statistics, Government of Telangana from 1966-67 to 2016-17 and it was analysed with the help of Markov chain by decade wise and for last decade, analysed for five periods. The major findings from the study revealed that any set of crops did not retain its area in Karimnagar, but the acreage of the crops was continuously shifting from one set of crops to another set throughout the period. The cereals area was observed to be more stable while the loss of area from cereals towards commercial crops like cotton and turmeric etc. Indicated that the cropping pattern of the region moves towards diversification in northern Telangana zone. There is a larger scope for deciding within the choice of crops to place the agriculture on the pedestal of property growth that has to be thought-about in analysis and extension programmes.

Dynamics of rice production among the food crops of Tanzania

“…The crop's column elements represent the area gained from other crops, while the crop's row elements indicate the area lost to other crops. [18][19][20] The average area shifted to a particular crop is a random variable that depends only on the previous crop's area, algebraically expressed as: where E jt is the area of the crop shifted towards the particular jth crop in the year t; E it -1 is the area lost by the ith crop during the year t-1; P ij is the probability that the area lost will shift from ith crop to the jth crop; E jt is the error term which is statistically independent of the E it -1; and n is the number of crops.…”

“…A first-order Markov chain analysis provides a base for study into the complexities of cropping trends and patterns by examining the area retention (stability of the area under various crops) and crop shifting from one set to another. [18][19][20] Despite many studies on the area, production, and productivity for major food crops undertaken for Tanzania in the past, there have been very few nationwide studies on rice in recent years. Mkonda and He 21 used the Mann-Kendall test to assess the development pattern of major food crops (five crops) and their efficacy on food security in Tanzania from 1980 to 2015.…”
