In India, 8.1 million hectares of land are salt affected. This poses serious problems in agriculture. Sustainable agriculture is related to soil quality. Proper appreciation of quality of a particular soil, demands the knowledge of physico-chemical, biochemical and microbiological parameters. This review deals with physico-chemical, microbiological and biochemical aspects of soil quality for saline soil, in general, and coastal saline soil of India in particular

This study deals with the quantitative assessment of nutritionally important fatty acids (FAs) in 94 indigenous rice (Oryza sativa ssp. indica) landraces of India which are critically endangered, being cultivated only by a handful of marginal farmers. Three modern high-yielding varieties and one local high-yielding farmers’ variety were analysed for comparative assessment. Qualitative and quantitative analyses of FAs based on gas chromatography-mass spectrometric analysis of these varieties revealed their significant contribution to daily diet. Two ‘case studies’ were considered on the basis of individual FAs and nutritionally correlated FA parameters of the rice cultivars to isolate the most promising landraces, by clustering through linear discriminant function. These folk rice landraces may add important precursors to essential FAs in the staple diet and can provide for FA requirement in normal brain development in infants. We suggest incorporation of these landraces into India’s food and agriculture policy, both for conserving the vanishing landraces and for ensuring nutritional security of the economically marginalized people.Keywords

Sunflower, an important oil seed crop, needs a balanced nutrition for its optimum growth and thorough maintenance of soil health. A field experiment was conducted to study the impact of integrated use of organic, inorganic and biofertilizers on soil fertility, soil organic carbon fractions, soil microbiological and biochemical parameters as well as yield of sunflower (cv. GK 2002) in alluvial soil at Agricultural Experimental Farm, University of Calcutta, Baruipur, India, during 2013–14 and 2014–15. There were ten different treatments with three replications. After analysis, the data clearly showed significant difference among treatments in sunflower yield and a prominent impact of integrated use of organic, inorganic and biofertilizers was found under the treatments. Microbial biomass carbon, basal soil respiration, activities of soil enzyme and different carbon fractions showed higher values for those treatments where only organic inputs were given. The best possible combination for higher seed yield was recorded in T10/T6 treatment (vermicompost 2.5 t ha–1 or FYM (5 t ha–1) with phosphate solubilizing bacteria @ 8 kg ha–1 soil application + Azotobacter @ 8 kg ha–1 soil application + 50% recommended dose of chemical fertilizers + foliar spray (2% urea)). T10/T6 treatment is thus recommended for sunflower cultivation in alluvial soil considering the soil quality and seed yield of sunflower.Keywords
