| effects of crop residues of sunflower (helianthus annuus), maize (zea mays l.) and soybean (glycine max) on growth and seed yields of sunflower. | this pot experiment was carried out at suranaree technology university experimental farm, northeast thailand to investigate effects of crop residues of sunflower, maize and soybean on total dry weight, top dry weight, plant height, root dry weight and seed yield of sunflower plants with the use of korat soil series (oxic paleustults) during the rainy season (july-october) of the 2001. the experiment was laid in a split plot arranged in a completely randomized design (crd) with four replications ... | 2007 | 19069929 |
| residual effects of applied chemical fertilisers on growth and seed yields of sunflower (helianthus annuus cv. high sun 33) after the harvests of initial main crops of maize (zea mays l.), soybean (glycine max l.) and sunflower (helianthus annuus). | the experiments consisted of two locations, i.e., the first one was carried out on a growers's upland area at saraburi province, central plane region of thailand with the use of chatturat soil series (typic haplustalfs, fine, mixed) and the second experiment was carried out at suranaree technology university experimental farm, suranaree technology university northeast thailand with the use of korat soil series (oxic paleustults). the experiments aimed to investigate the effect of residual effect ... | 2007 | 19069898 |
