Title

RECOVERY OF RESIDUAL FERTILIZER NITROGEN BY CANOLA IN A WINTER CANOLA-FORAGE MAIZE ROTATION

Pages

  75-83

Abstract

 Fertilizer N residual use in agriculture is recognized worldwide as an alternative fertilizer and to a sharp decrease of the nitrate concentration in seepage water recharging the groundwater. In order to evaluate RECOVERY of residual fe1tilizer-nitrogen by canota in a canota-forage maize agroecosystem, a field experiment was conducted at research farm of Shahrekord University, 2008-2009. Experimental design was a randomized complete block with four replicates. Treatments include residues of 0, 100, 200 and 300 kg N ha-1 in the form of urea and broiler litter which that this soil amendments were applied in spring for maize as prior crop. CANOLA was planted in mid­ September following forage maize harvest. The results showed that broiler N residual increased pod/plant, seed/pod, 1000 seed weight, grain yield, dary matter, oil concentration and oil yield compared with the N residual of urea. The greatest pod/plant, 1000 seed weight, grain yield, oil concentration and oil yield were obtained with 300 kg N ha-1 from source of poultry litter, but 200 kg N ha-1 from broiler Jitter produced the highest seed/pod and biological yield. In conclusion, utilization N residual after maize harvest would help to minimize the use of high cost synthetic mineral fertilizers for CANOLA production and represents an ENVIRONMENTally and agronomically sound management strategy.
