Effects of Irrigation Water Quality on the Recovery of 15N- Fertilizer by Sorghum in Field Study

15N-labeled fertilizer was applied to Sorghum at different rates (0, 100 kg N.ha -1 ) to 1m2 microplots and with two kind of water (well water “WW” and treated wastewater “TWW”) to Sorghum grown in field during 1997 and 1999. Increases in DM production, N uptake and 15 NRF were observed with TWW. About 17% and 36% of the 15Nfertilizer were recovered in the crop with TWW in 1997 and 1999, respec...

Impact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice

Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...

Assessment Effect of Different level of Nitrogen Fertilizer (Urea Source) and Interval between Irrigation Round on Crop Production of Sorghum (Sorghum bicolor L., cv. Speed feed)

BACKGROUND: Nutrients play a very important role in chemical, biochemical, physiological, metabolic, geochemical, biogeochemical, and enzymatic processes. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Conventional deficit irrigation is one approach that can reduce water use w...

Effect of Irrigation and Planting Date on the Selected Morphophenological and Quality Traits of Ajowan (Carum copticum BENTH. & HOOK.F.)

In order to study the effects of irrigation and planting date on selected traits of ajowan (Carum copticum BENTH. & HOOK.F.) an experiment was conducted in two successive conducive seasons of 2009/2010 and 2010/2011 in Birjand. The experimental design was a split plot based on randomized complete block with three replications. In the present study, two irrigation treatments (irrigation terminat...
