ABSTRACT
The correlations studies of Musi command area in Nalgonda indicated that, the soil EC was positively and significantly correlated with organic carbon (r = 0.29), and available phosphorus (r = 0.5). Organic carbon was positively and significantly correlated with phosphorus at 1 per cent level of significance. Pre monsoon bore well pH was positively and significantly correlated with SAR (r = 0.626), and Fluorides (r = 0.60), EC was positively and significantly correlated with nitrates (r = 0.45) in open wells at 1 per cent level of significance. The RSC in bore wells was negatively and significantly correlated with chlorides. Post-monsoon bore well pH was positively and significantly correlated with SAR, and fluorides. Post-monsoon EC of bore well was positively and significantly correlated with nitrates, chlorides and ammonia. The SAR in open wells was negatively and significantly correlated with RSC in open wells. Paddy yield was positively and significantly correlated with available nitrogen, available phosphorus and potassium.
