(2012-01-12)
Water is vital for live as such including a wide range of livelihood activities including domestic and productive needs. Access to adequate water supply would significantly contribute to poverty alleviation, whereas lack ...
Comparison of DRIS and critical level approach for evaluating nutrition status of wheat in District Hyderabad, Pakistan
(2012-03-07)
Intensive cropping systems, improper use of fertilizers or no fertilizer application, and unreliable and poor quality of irrigation water have led to declining soil fertility in the district of Hyderabad, Pakistan. To date, ...
