Biometria de sementes de variedades crioulas de feijão-caupi cultivadas por agricultores familiares na região de Apodi/RN.

Abstract

The term "creole seeds", although little known by the academy and by the population, is not something outside the productive reality in Brazil. Cowpea beans, which are largely made up of creole varieties, are of great importance in the northeastern region of Brazil, being one of the nutritional sources, mainly of agricultural families. The objective of this study was to study the biometry of seeds of cowpea bean varieties cultivated by family farmers in the region of Apodi/RN. Six varieties of cowpea (Vigna unguiculata) seeds were worked. Of these, five were native seeds and one commercial cultivar developed by EMBRAPA in partnership with a private company of seed production tracking. The creole seeds used were: Owl, Canapum, Lizão, Sem Verde Green, Ribeiro de Vaca and BRS Potiguar was the commercial cultivar used to make the comparisons. Samples of the seedlings were collected in the Brice Potiguar cultivar, collected at the EMATER-RN office in the Serra do Mel / RN office. . The characteristics analyzed were: length, width, length / width ratio, weight of one hundred seeds, weight of one thousand seeds, quantity of seeds per kilo. Statistically, the Tukey test was used at a 5% probability level to compare the means. There was a statistical difference between the cultivars of cowpea for the biometric characteristics studied. The cultivar Creole cow 's rib was statistically superior to the characteristics of seed length, length length, weight of one hundred seeds and weight of one thousand seeds, with average values of 11.37 mm; 2.14 mm; 31.16g and 312.46g, respectively. The BRS potiguar variety was statistically superior for the characteristic amount of seed per kilo, with a value of 5,099.16 units / kg. Considering the analyzed variables and the results obtained, it is possible to point out to the Creole cow rib variety as the best alternative for the family farmer among the six that were tested.
