ABSTRACT: A study was carried out in the Teaching and Research Farm of Delta State University, Asaba Campus in 2005 to evaluate the effects of five different staking methods on the growth and development of Telfairia occidentalis. Five treatments involving different staking methods were replicated three times in a randomized complete block design. Data collected were subjected to analysis of variance. The result indicated a positive or significant influence of staking on the yield and yiels component of T. occidentalis: Plant growth and yield were better under staking than when allowed to creep on the ground. Raised platform proved to be the best method of staking and was recommended with a view to exploiting the great economic potentials of crop.

ABSTRACT: The present investigation was conducted to elicit information on extent of genetic variability, heritability and genetic advance for twenty-one characters in 84 intrahirsutum cotton hybrids (Gossypium hirsutum.L) plus two checks which were derived by involving twelve lines and seven testers in line X tester fashion. These lines were developed from new heterotic genepools. These 84 intrahirsutum cotton hybrids along with two checks were evaluated during kharif 2010-11. Wide variability was observed incase of number of sympodia, specific leaf weight, crop growth rate at peak flowering stage, crop growth rate at boll formation stage, crop growth rate at maturity stage. High heritability accompanied by high genetic advance was observed in case of plant height, number of monopodia, number of sympodia, relative water content, specific leaf weight, crop growth rate at peak flowering stage, crop growth rate at boll formation stage, crop growth rate at maturity stage, boll weight, seed index and lint index indicating the role of additive gene action in the inheritance of these traits and directional selection could be profitably applied on these traits in the genetically diverse material.
