Zinc (Zn) deficiency is the most widespread micronutrient deficiency in crop plants and humans. Low intake of Zn through diet appears to be the major reason for the widespread prevalence of Zn deficiencies in human populations. Application of Zn fertilizer in soil having low Zn increased the grain yield in wheat up to 6.4β50.1%. However, soil Zn application increased the grain yield of rice only up to 7.2β14.8%. Soil having sufficient Zn had no or little effect on grain yield with soil Zn application. The application of foliar Zn with or without propiconazole resulted in significant increases in grain Zn irrespective of soil Zn status. Application of foliar Zn along with propiconazole at earing and milk stages proved beneficial in increasing grain Zn content in both rice and wheat. Hence agronomic biofortification is possible and could be considerably economical if used along with a fungicide depending upon appearance of a disease.Keywords

The present research study has been conducted with prime objective to investigate the chemical fractions of Zn and Cu under 10 cropping systems in alluvial soils. Surface (0-15 cm) soil samples were collected from an ongoing field experiment (in progress since 2000) with 10 cropping systems at research farm of Department of Agronomy, PAU, Ludhiana. These soil samples were analyzed for total Zn and Cu and their chemical fractions using atomic absorption spectrophotometer (Varion AAS-FS Model). Among chemical fractions, higher levels of Zn (WSEX, SpAd, MnOX and CFeOX) and Cu (WSEX and OM bound) were reported under maize-potato-mungbean and cotton-gobhi sarson cropping systems respectively. Among fractions, SpAd, held on organic sites, oxide bound and amorphous fractions of Zn and Cu contributed towards plant available (water soluble and exchangeable) fractions.Keywords

A field experiment was conducted in department of Plant Breeding (Fodder Section) during 2002-03. Different levels of Zn, Mn, B and Mo were tested to increase the production efficiency of seed. The results revealed that different levels of micronutrients increased the seed yield of berseem in the range of 189-312 Kg ha-1. The concentrations of zinc @ 0.5 and 1.0 per cent increased the seed yield of berseem by 7.2 and 18.5 per cent, respectively, over control whereas, maximum increase in seed production efficiency was recorded by 42 per cent with foliar application of 4 Kg ha-1 B. The minimum per cent increase in seed production was recorded by 7.2 per cent with 0.5 per cent foliar application of zinc as ZnSO4.Keywords
