(700–1200 mm yr-1). The Vertisols contain high (40–60%) montmorillintic clay and exhibit typical swelling and&#13;
shrinking characteristics under moist and dry conditions. Vertisols have poor hydraulic conductivity and conse-&#13;
quently, are frequently poorly drained. Traditionally farmers grow a secured postrainy season crop on stored soil&#13;
moisture and keep the fields fallow during rainy season. The most dense region of rainy season fallowing in semi-&#13;
arid tropical India covers areas endowed with Vertisols.&#13;
           Realizing the potential of Vertisols in supporting a short-duration crop during rainy season, which&#13;
otherwise is left fallow, a pilot study was taken up by ICRISAT to delineate the rainy season (kharif) fallows in&#13;
Madhya Pradesh. The Indian Remote Sensing Satellite (IRS-IC/-ID/-P3) Wide Field Sensor (WiFS) data acquired&#13;
during peak kharif, post-kharif, and mid-rabi cropping season was used. The analytical approach employed&#13;
involves geo-referencing and radiometric normalization of multi-temporal WiFS data, and delineation of kharif&#13;
fallows in a Silicon Graphic Work Station using ERDAS/IMAGINE software and&#13;
a per-pixel Gaussian maximum likelihood algorithm and limited field check. While mid-kharif and post-kharif&#13;
season WiFS data enabled detection of lands that remain fallow during kharif season, mid-rabi season WiFS data&#13;
allowed further verification of the delineation since such lands have been found supporting mostly wheat crop&#13;
during rabi season. An estimated area of 2.02 million ha, accounting for 6.57% of the total area of the state is&#13;
lying fallow. Utilization of kharif fallows for short-duration pulse crops like soybean may help not only to boost&#13;
agriculture production but also to improve the sustainability of the agro-ecosystem and minimize land degrada-&#13;
tion.&#13;
