Effects of insulin-like growth factor I (IGF-I) polymorphism on bodyweight of Nigerian indigenous chickens

A total of 101 randomly selected birds from a population of 601 birds (obtained from a 3×3 diallel mating system involving normal, frizzle and naked neck Nigerian indigenous chickens) were used to evaluate the effects of insulin-like growth factor I (IGF-I) polymorphism on bodyweight. Blood samples for DNA analysis were collected at 20 weeks of age. IGF-I genotypes were identified using polymerase chain...

Bentonite application in the remediation of copper contaminated soil

The concern on heavy metals from commercial fertilizers for fertilization of crops when they are intended for human consumption has increased specifically, horticultures and grains. Several procedures have been proposed to reduce the concentration of heavy metals in the soil; among these are, the application of materials that are able to adsorb these elements, making them less available to plants. This study aimed to...

Nutritional assessment of potassium in tomato (Lycopersicon esculentum Mill.) by direct reading of fruit sap

Analysis of content made available to the plants and their relationship with what is present in plant tissue, are great alternative for proper handling of fertilizer, but the methods currently used, are expensive and require time. This study aimed to implement a new methodology for its determination and thus develop a correlation with the conventional method. It also evaluated the influence of the increase of K doses in...

Growth and physiological responses of sunflower grown under levels of water replacement and potassium fertilization

Water deficit is one of the limiting factors of agricultural production, especially in semi-arid regions. In this sense, the aim of this study was to evaluate the growth and the physiological characteristics of sunflower cv. Hélio 251 at different levels of water replacement and potassium doses in an experiment conducted in the greenhouse of the Center for Technology and Natural Resources of UFCG, Campina Grande,...
