Comportamiento del crecimiento y el rendimiento de la variedad de papa (Solanum tuberosum L.) Spunta

the work was developed in the national institute of agricultural sciences with the objective of evaluating the behaviour of the growth and its relationship with the yield in one commercial variety of potato (spunta). the plantation was carried out following a muestreal design during two years, 2009 and 2010. they were carried out destructive samplings in different moments after the plantation until the crop, to determine the number of shafts average for plant, the number of leaves average for shafts, the leaf area from the lineal measures (long and wide) of the leaves, the accumulation of dry mass in the different organs and the yield (expressed as average by plant). in the moment to do the evaluations were took 10 plants at random every time from the experimental area, they were separated in their different organs. in general was demonstrated the influence of the years in the behaviour of the plantation in the values reached in all variables considered, except in the number of shafts average for plant, aspect were the climatic conditions had a beg influence, but too the more efficiency of application of the raining in the second year.
