    In the entire world, the main nutritious source for the herbivores is the grass, in the countries that have four stations, with silage processes and haymaking, the food is reserved to provide it when there is not fresh grass Maralfalfa to be a hybrid one has characteristic of gramineous and leguminous, for what makes sure with a single grass, the enough quantity of fiber and protein that the livestock needs for a good production of milk or meat. This investigation was carried out in the experimental Treasury of the Agricultural Technological Institute Luís A. Martínez, located to an Altitude of 2.689 msnm, with a temperature average of 15 oC and a precipitation annual average 300 mm. The floor was of sandy frank type, a pH of 7,6, contained first floor of Matter Organic 4,42%. The objectives that thought about in this investigation were:  Evaluate the productivity of the grass Maralfalfa, by means of two types of asexual multiplication and two organic payments.  Evaluate the productive characteristics of the grass Maralfalfa, in order of the studied treatments.  Determine what type of organic payment that he/she helps to the biggest productivity of grass maralfalfa.  To carry out the economic analysis. An Experimental Design of Complete Blocks was used at random (DBCA) in factorial arrangement of 2x3 with 4 repetitions. The factor A it corresponded to propagation systems: A1: Stumps and A2: Shafts. The factor B constituted types of payments: B1: Witness 0 TM/Ha; B2: Bovine 10 TM/Ha and B3: Ovine 20 TM/Ha Was carried out chemical analysis of the floor and the organic payments, variance analysis, Test of Tukey to 5%, Correlation and lineal regression and of the relationship benefit cost. 84 The main obtained results were:  The system of more efficient propagation reflected in the agronomic components and the yield of grass maralfalfa was that of Stumps with 11.718 Kg. /ha, what meant an increment of the yield of 2.617 Kg./ha in comparison to the system of shafts.  An answer existed very different from the payment types in relation to the agronomic components and the yield of green matter. The payment type with the yield higher average was B2: Bovine 10 TM/Ha with 12.110 Kg./ ha.  In the interaction of factors the yield higher average, registered in the treatment T5: Shafts of Maralfalfa + Bovine 10 TM/ha with 12.890 Kg./ha.  The independent variables that contributed to increase the yield of green matter were the Percentage of Apprehension and Volume of Root to the 60 and 90 ddt.  The variable that reduced the yield of green matter was the Diameter from the Shaft to the 80 and 90 ddt.  Economically the technological alternative with the highest net profit in function only of the costs that varied for treatment it was the T 5: Propagation System for Shafts of Maralfalfa + Bovine 10 TM/Ha with a value of the RB/C 9,21 and a RI/C 8,21.  The relationship lower benefit-cost was reported in the T3: Propagation Systems for Stumps of Maralfalfa + ovine 20 TM/Ha with 2,15.  Finally this investigation allowed to improve the production and productivity of the grass significantly Maralfalfa, when validating a propagation system and the type and payment dose adapted for this ecological area agriculture
