Currently the production of plants in nurseries traditional not have suffered changes significant, despite know that them estate of these plants in the field are susceptible to them nematodes (Meloidogyne sp and Pratylenchus sp) and other pests that affect the growth and the productivity of the grain; an alternative to this problem, is the grafting of varieties Arabic on patterns of coffee robust , technology that presents advantages for the control of nematodes parasitic, since the species robusta is considered as less susceptible. The objectives of this research were: I measure the effect of three patterns for the graft Hipocotiledonar in coffee Arabica; II evaluating three varieties of coffee Arabica for the graft hipocotiledonar; III study the interaction patterns and varieties for the production of seedlings of Arabica coffee in the nursery and IV carry out an economic analysis of partial budget and calculate the Marginal rate of return (TMR %). The essay is led under a design of blocks complete to the random (DBCA) in arrangement factorial common 3 x 3, with the complement of the comparison of middle of them treatments by the test of Tukey when the Fisher was significant. Also be performed the analysis economic of budget partial and calculation of the rate Marginal of return (TMR %). Of the main results obtained can deduce that plants grafted between Arabic varieties and patterns of robusta coffee were not health problems; prendimiento of grafts was greater than 95%; evaluated agronomic variables did not show statistical differences to 150 days after made graft; in Arabic varieties stresses the variety Sarchimor 1669 and in patterns of robusta coffee stresses genotype ETP: 3752 - 6, at the nursery level. |
