) Effect of some weed control treatments on sugar cane yield (Saccharum officinarum L.) and the associated weeds
Abstract: Four field experiments were carried out at El-Mattaana Agricultural Research Station, Agricultural Research Center, Esna, Quna Governorate during 1999 / 2001 and 2001 / 2002 growing seasons. The present investigation aimed to study the effect of some herbicides either individuals (metribuzin metribuzin at 300 g/fed,, metosulam at 80 cc/fed, tribenuron at 8 g/fed. and glufosinate at 2 L/fed.) or in combinations (metribuzin plus glufosinate, metribuzin plus hand hoeing once, glufosinate plus glufosinate, glufosinate plus hand hoeing once) compared to hand hoeing at 3 and 4 times on sugar cane yields the associated weeds, The obtained results from both season showed that all weed control treatments either individuals at 60 and 150 days after planting (DAP) or in combination at 90 and 150 (DAP) gave significant effect on controlling the weeds. Hand hoeing at 4 times, hand hoeing at 3 times and metribuzin at 300 g/fed as individual treatments gave the highest reduction on the dry weight of broad-leaved weeds at 150 DAP by 93.3, 81.1 and 70.1 in 1st season and by 95.0, 84.8 and 72.4 %, respectively in 2nd one as compared with control treatment. Hand hoeing at 4 times, hand hoeing at 3 times, metribuzin at 300 g/fed. plus glufosinate at 2 L/fed. as combined treatments gave the highest reduction on the dry weight of broad-leaved weeds at 150 DAP by 87.9, 84.3, 72.4 and 71.6 % in 1st season and by 90.7, 83.4, 69.9 and 68.4 %, respectively in 2nd season as compared with control treatment. Meanwhile, hand hoeing at 4 times and hand hoeing at 3 times either individuals or in combinations gave the highest reduction on dry weight of grassy weeds at 150 DAP from 75.2 to 86.3 % in both seasons as compared with control treatment. Al weed control treatments gave significant effect on increasing sugar cane yields and its components in both seasons, where the hand hoeing at 4 and 3 times were superior treatments. Hand hoeing at 4 times in the first two experiments gave highest value of cane yield and sugar yield by 43.95 and 6.13 t/fed, in 1st season and by 42.41 and 5.97 t/fed, respectively in 2ndseason. The yield of sugar cane was significantly increased from respective treatment by by 43.44% in 1st season and 38.87 % in 2nd season as compared with control treatment. Similar result was obtained from hand hoeing at 4 times in the other two experiments where it gave highest value of cane yield and sugar yield by 48.62 and 6.81 t/fed in 1st season and by 47.35 and 6.73 t/fed in 2nd one, respectively as compared with control treatment. The yield of sugar cane was significantly increased from respective treatment by 44.1% and 51.9% in 1st season and 2nd season, orderly as-compared with control treatment. The other treatments of either individual or in combinations gave the highest values of stalk height (cm), stalk diameter (cm) sucrose (g/100ml), purity %, sugar can yield (t/fed) and sugar yield (t/fed) in both seasons.
