    Abstract

    Analysis of soils from 421 farmers' fields in eastern districts of Rajasthan, India revealed widespread deficiencies of sulfur (S; 43 to 87% fields deficient), boron (B; 25 to 100%), zinc (Zn; 0 to 94%) in addition to phosphorus (P; 10 to 73%) and soil organic carbon (1 to 84%). Integrated approach of application of deficient sulphur, boron and zinc along with nitrogen and phosphorus to high yielding crop cultivars increased yield over farmers' practice of nitrogen and phosphorus application to local cultivars by 92 to 204% in maize, 115 to 167% in pearl millet and 150% in groundnut. Benefit to cost ratio of the integrated strategy varied from 3.33 to 8.03 in maize, 2.92 to 3.40 in pearl millet and 1.15 in groundnut. Integrated approach effectively utilized scarce water in food production and increased rainwater use efficiency at 67 to 145 kg mm−1 ha−1 from 21 to 50 kg mm−1 ha−1 under farmers' practice.
