This study was designed to evaluate the effects of some root - promoting substances on rooting andmini tuber formation using vine cuttings obtained from two genotypes (TDr 335 and TDr 93 - 49) of whiteyam (D. rotundata). The ashes were obtained from rice straw, bamboo, Gliricidia sepium, dry leav...

Effects of synthetic hormone substitutes and genotypes on rooting and mini tuber production of vines cuttings obtained from white yam (Dioscorea rotundata, Poir)
A reliable means to induce sprouting in dormant seed tubers of yams (Dioscorea species) is required to enhance flexibility in planting date and rate of propagation of the crop. Experiments were conducted to assess the potential of two gibberellin inhibitors, Uniconazole-P and Prohexadione-calcium...

To induce sprouting two gibberellin inhibitors, uniconazole-P (UP) and prohexadione-calcium (PC), were applied to foliage of white Guinea yam (Dioscorea rotundata) and water yam (D. alata) 30 days before harvest or to tubers at harvest. The tuber sprouting period was shortened by about 35 days in...

La concurrence des mauvaises herbes est un obstacle à la rentabilité de la production du manioc. La connaissance des espèces de mauvaises herbes qui affectent négativement la productivité du manioc est essentielle pour une gestion efficace. Une étude a été conduite entre mai et juin 2014 et 2015 ...

Sixty-day-old plants of white Guinea yam (Dioscorea rotundata), water yam (D. alata) and yellow Guinea yam (D. cayenensis) were exposed to 10 h day lengths (short days) for 15 and 30 days. Short-day treatment applied at the early growth stage of yams promoted the enlargment of tubers, but the res...

Seed tuber production of Dioscorea rotundata using the minisett technique was tested on-farm and on-station in different agro-ecological zones in Nigeria. A lower sprouting rate of minisetts was observed in the southern Guinea savanna than in the tropical forest zone. Sprouting and tuber yield in...

In experiments in 2001 to 2003, 50-day-old plants of four varieties of white Guinea yam (D. rotundata) were exposed to 10 h (short-day) day length for 15 days, 14 h for 30 days or constant 24 h, with natural day length as the control. Under natural day length the male varieties flowered earlier t...
