Synthetic fertilizers solved soil fertility problems, which increased yields per unit area, although they led to high economic, environmental and social costs.1,2 Continue to be preferred by producers for plant growth, in more than 70% of agricultural lands with corn they apply nitrogen fertilizers, Guerrero is no exception, it is still using nitrogen fertilizers through out the State, however, it is frequently lost due to volatilization and erosion,3 and has also caused pollution to the environment.
Agro ecosystems faced eterioration due to the constant use of synthetic fertilizers, there fore, it is important to resume peasant agriculture, in which small farmers appropriate innovations and transition to the production of foods free of agrotoxics, as noted by Montoya et al.4

Sesame seeds are important in human, live stock and industrial nutrition. The objective was to evaluate the response of 6 geno types of sesame (Sesamumindicum L.), Iguala, Guerrero, Mexico. The experimental design was in divided plots: chemical and organic, with 4 blocks and 6 subplots distributed at random and 4 repetitions; The experimental plothad three 4 m long furrows; The useful unit was the 2m central furrow, 1 m was eliminated on both sides and the edge furrows. The distance between rows at 0.75m and distance between plants at 0.1 m, the geno types were: Criolla Mazón, Negro Paraguay, Vara Verde, Tres Huesillos, Calentana and Canasta. 6 central furrow plants per geno type were labeled and evaluated. The study variables were: number of branches, number of capsules, seed weight and weight of 100 seeds. Analysis of variance and Tukey test with SAS Version 9.0. It turned out that between chemical and organic fertilization there was no significant difference, while the number of branches, number of capsules, seed weight and weight of 100 seeds, with R2 of 78%, 72%, 65% and 59%, respectively, the Response variability is attributed to chemical and organic fertilization on the geno types. The Calentana variety surpassed the rest of the geno types in number of capsules, seed weight and weight of 100 seeds. It is concluded that chemical and organic fertilization had similar responses, while the Calentana variety out performed the other geno types.
Chemical and organic fertilization showed similar results, so, in hybrid production, synthetic fertilizers will be gradually replaced by organic fertilizers and bio stimulants in sesame agro ecosystems.
