The life cycle of Puccinia digitariae on Digitaria eriantha and Solanum species in South Africa
Mycologia, 2022Rust fungi are important plant pathogens and have been extensively studied on crops and other host plants worldwide. This study describes the heterecious life cycle of a rust fungus on Digitaria eriantha (finger grass) and the Solanum species S. lichtensteinii (large yellow bitter apple), S. campylacanthum (bitter apple), and S. melongena (eggplant) in

An experiment was conducted to investigate the influence of stage of growth at harvest on fermentative characteristics of Digitaria eriantha subsp. eriantha silage. The treatment included three different growth stages (early vegetative, boot stage and full-bloom stage). The materials were ensiled either directly (unwilted) or after wilting for a period

The performance of beef cows on Digitaria eriantha silage
Journal of the Grassland Society of Southern Africa, 1990Digitaria eriantha silage, ensiled when the plants were in the late flowering stage (March), was fed ad lib to mature, non‐pregnant, dry Hereford cows from mid‐May to mid‐September. The average daily gain during a 98‐day feeding period was 0,35 kg/cow.

In vitroregeneration ofDigitaria eriantha
Journal of the Grassland Society of Southern Africa, 1988Embryogenic callus was obtained from immature regions of the leaf of Digitaria eriantha when grown in the dark on a MS medium supplement with 1, 0 or 2, 0 mg/dm 3, 2, 4D and 3-9% sucrose. Plantlet regeneration occurred when the calli were transferred to MS medium containing 0, 1 mg/dm 3, 2, 4-D and 7-8% sucrose, and placed under 16 hour photoperiod ...

Abstract Digitaria eriantha Steud. subsp. eriantha, plants were grown under controlled conditions and treated with different concentrations and forms of nitrogen. The plants showed a preference for nitrate nitrogen, as opposed to ammonium nitrogen, with greater total dry matter production and leaf areas being recorded.

A production function is derived and calibrated for Digitaria eriantha hay production in the Highveld region of the RSA. A procedure is described that optimizes this function for nitrogen and phosphorus application rates within economic and risk constraints at different expected rainfall levels.

Yield and quality of fertilized deferred forage of Digitaria eriantha and Eragrostis curvula
Journal of Arid Environments, 2001Abstract A cutting experiment was carried out in Bahia Blanca (Argentina) during 1998 and 1999 using a randomized block design in a 2 3 factorial experiment: (1) the species Digitaria eriantha and Eragrostis curvula , (2) 0 and 60 kg Nha −1 fertilizer treatment and (3) deferred harvesting on 1 June and 15 July.

The effect of form and level of nitrogen fertlization on the yield of Digitaria eriantha Steud
Journal of the Grassland Society of Southern Africa, 1987On dryland Digitaria eriantha ammonium sulphate and limestone ammonium nitrate were superior to potassium nitrate and urea. With reference to the level of nitrogen fertilization it was found that levels in excess of 300 kg N/ha, and up to 400 kg N/ha, could be economically justified, even on a pasture with a high basal level of fertility.Language ...
