Nutrient Partitioning and Stoichiometry in Unburnt Sugarcane Ratoon at Varying Yield Levels
Unraveling nutrient imbalances in contemporary agriculture is a research priority to improve whenever possible yield and nutrient use efficiency in sugarcane (Saccharum spp.) systems while minimizing the costs of cultivation (e.g., use of fertilizers) and environmental concerns. The main goal of this study was therefore to investigate biomass and nutrient [nitrogen (N), phosphorus (P), and pota...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Ratoon stunting disease of sugarcane: isolation of the causal bacterium.
A small coryneform bacterium was consistently isolated from sugarcane with ratoon stunting disease and shown to be the causal agent. A similar bacterium was isolated from Bermuda grass. Both strains multiplied in sugarcane and Bermuda grass, but the Bermuda grass strain did not incite the symptoms of ratoon stunting disease in sugarcane. Shoot growth in Bermuda grass was retarded by both strains.
متن کاملEffect of Ratoon Stunting Disease on the Yield and Components of Yield of Sugarcane under Rainfed Conditions
In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...
متن کاملThe Effect of Ratoon Stunting Disease on the Yield of Some South African Sugarcane Varieties under Irrigated and Rainfed Conditions
The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...
