Abstract
An experiment was conducted during the rainy season of 1999 and 2000 at Zonal Agricultural Research Stc tion, Konehally, Tiptur, to study the influence of 3 row spacings (30, 45 and 60 cm) and 4 cutting managements on guinea grass (Panicum maximum Jacq.) under irrigation. PImong ?he growth parameters, the number of tillers/m row alone was significantly higher at wider spacings. The tillering was significantly profuse when the crop was cut for fodder cum seed purpose at later cuts than at first cut. The green fodder yield was significantly influenced by cutting management. However, the seed yield was not influenced significantly by row spacings and cutting man agement. The closer row spacing of 30 or 45 cm and managing the crop with fourth cut for fodder cum seed pur pose giving a green fodder yield of 55 58.5 tonnesfha and a seed yield of 105 1 15 kg/ha appeared optimum for PGG 51 8 guinea grass under irrigation.
