Abstract
barley forage organic and in organic fertilizer Organic and mineral fertilizers influences on forage barley production are not well known in Sistan region. Field experiment was established in autumn 2012 in Sistan research station center to determine the organic and inorganic manure and mixture of them effect on quality and quantity yield barley (HordeumVulgare l.). Six treatments were tested in a complete block design: (A) mineral fertilizer (NKP) an optimal dose (according to the Iran fertilization guidelines), (B) sub fertilization (2/3 of the optimal dose), (C) sub fertilization (1/3 of the optimal dose), (D) animal manure 60 t h-1( an optimal dose), (E) 1/2 of animal manure plus 1/2 of mineral fertilizer and (F) control. The treatments have a significant effect on quality and quantity barley forage. When NKP-fertilization were non-limited (optimal dose) and 1/2 manure plus 1/2 NKP was applied, CP, fresh and dry matter forage have more yielded than those in treatment whit other of them. The sub fertilization (1/3, 2/3 of optimal dose and control) decrease the fresh and dry matter yields by 19400, 5560 and 26487 kg ha-1 respectively. In conclusion, optimal dose (A) and 1/2 of animal manure plus 1/2 of mineral fertilizer (E) provide effective means to conserve soil fertility and forage production in this study. Splitting of organic manure inputs in short term did not bring any benefits to soil properties or crop production.
