Abstract

In order to study the effect of NITROGEN rates and PLANT DENSITY on forage yield and quality of pearl millet (Pennisetum americanum var. nutrifeed) an experiment was conducted at Agricultural Research Station of Torogh region, Mashhad, Iran on summer 2003. Experiment was carried out in split plot based on Randomized Complete Blocks Design with 4 replications. Three levels of PLANT DENSITY (D1=20, D2=13.3 and D3=10 plant/m2) and three levels of NITROGEN rate (N1=200, N2=300 and N3=400 kg N /ha from Urea source) were arranged as main and minor factors respectively. According to main object of this research Qantitative traits (fresh and dry forage yield, Leaf stem ratio, tiller number per plant, tiller number per area and stem diameter) and qualitative attributes (%OM, %Ash, %CP, %Ca and %P) were measured in first and second cutting biomass. Results showed that NITROGEN rate affected all the quantity traits significantly, in such a manner increased N use from 200 to 400 Kg N /ha increased 17.15 and 23.83 percent of fresh and dry forage yield respectively. Lake of significant difference in forage yield between plant densities levels, referred to high tillering ability of nutrifeed millet. Comparison of LAI and tiller number/plant and tiller number/m2 in different treatments indicated that increment of N and density increased dry forage yield through increasing LAI and tiller number per area. Meanwhile Leaf/Stem ratio was decreased. Finally it could be stated, maximum dry matter (18.39 t/ha) and FRESH FORAGE yield (109.43 t/ha) were obtained using 400 Kg N/ha for density of 100000 plant/ha (D3N3 treatment). Also regarding to sustainable agriculture objects we could suggest the D3N1 in the superior treatments group because of its low PLANT DENSITY (10 P/m2) and low NITROGEN rate (200 kg N/ha). FRESH FORAGE production in this treatment was 94.37 ton/ha. It should be mentioned that N rate and PLANT DENSITY have not significant effect on forage quality.
