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
Cropping Systems, Micronutrients (Zn and Cu), Chemical Fractions.- Seed Production of Egyptian Clover [Trifolium alexandrium (L.)] as Influenced by Foliar Application of Zn, Mn, Mo and B on Loamy Sand Soil

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
