Abstarct: Few decades the use of chemical inputs in agricultural land, causing numerous environmental problems including pollution of water resources, crop quality and reduce soil fertility, poisoning humans, livestock and aquatics, beneficial insects and micro loss of soil . Sustainable agriculture, bio-fertilizers are used to eliminate or substantially reduce the use of chemical inputs, an optimal solution to overcome these problems is considered. Biological fertilizers containing preservatives with a dense population of beneficial organisms splashing or if one or more of these mextabolic products are available, to improve soil fertility and supply the proper nutrients needed by plants in sustainable agriculture systems are used in a. In today's society, the daily volume of organic waste into the environment are huge. Burial or burning of this waste, in addition to environmental pollution, irreversible damage to the economy of each community will enter. Devising appropriate solutions to optimize the use of organic waste, they can re-enter the production cycle and their potential use. One of the most effective strategies for the reuse of agricultural waste into compost and vermicompost.. Therefore, a factorial experimental design as a randomized complete block with three replications Treatments consisted of four level of Humic acid zero (control), 700, 1400, 2100 ml per hectare, and the three vermicompost zero (control), 4 and 8 ton per ha, that the effects of these two substances on the number of tubers per plant, stem height, tuber dry weight, biological yield and tuber yield was significant statistically. Also sprayed with 700, 1400, 2100 ml Humic acid were increase 5.6, 11.8, 19.4 ton compared to control.
