Effect of the crop succession and the organic and mineral fertilization on the yields of the tobacco cultivated in the sun

The effect of the precedents cultural corn (zea mays L) and been (vigna unguiculata L (Walp) was studied, as well as the combination of mineral and organic fertilization on the yield of the cultivation of the black tobacco (Nicotiana tabacum L.) variety Havana 92 cultivated in the sun on a fluvisol soil, in the agroclimatical area "Los cayos", Yara municipality, province of Granma, during the periodid 2006 - 2007. A totally randomized design was used, with a number of samples of 10 plants for each treatment to measure the variables wide and zize of the leaves, later on the agricultural yield was determined weighing the total number of leaves of each treatment in dry base later to the cured. Was proven that the experimental variants where it was included the organic fertilization and the combination of corn + vigna + tobacco didn't show significant differences to each other in the variable width and longitude of the leaf, achieving the biggest agricultural yield when combined the mineral fertilization and the organic with a value of 1313.25 kg. ha(-1).
