Abstract :An experiment was conduced to study the effects of a mixture of charcoal with pyroligneous acid (charcoal 4 : pyroligneous acid 1 ; Sannekka E) on dry matter production and root growth of summer planted sugarcane. Sugarcane variety NCo310 was tested against four levels of Sannekka E (SE) ; 0 (control), 200, 400, and 800 Kg 10a^<-1> and the experiment was laid out in a randomized complete block design with five replications. Yield contributing characters, such as stalk number, stalk length, stalk diameter and sugar content in stalks were increased by application of SE. Values of CGR, NAR and LAI of SE treated crops were higher in comparison to those of the controls. The correlation coefficients between CGR and NAR, and CGR and LAI were significant. The yield of cane stalks, sugar and total dry matter content in SE treated plots had been increased by 13-24%, 19-31% and 14-20%, respectively, over the controls. The highest cane stalk yield (11.4 kg m^<-2>), sugar yield (1.95 kg m^<-2>) and total dry matter content (4.4 kg m^<-2>) were obtained by the application of SE of 400 kg 10a^<-1>. Root content in unit soil cover depths was higher in SE treated plots.
木酢液・木炭混合物(サンネッカE)が夏植サトウキビの乾物生産および根の生育に及ぼす影響を明らかにするために、サトウキビ品種Nco310を供試し、サンネッカE施用量を0(対照区)、200、400および800kg/10aの4水準設定して5反復で実験を実施した.その結果、サンネッカE施肥により茎重、茎長、茎径、糖含量等のサトウキビの収量構成要素が増大した.サンネッカE施用区におけるCGR、NARおよびLAIは対照区より高い値を示し、CGRとNARおよびLAIの相関は有意であった.原料茎収量、蔗糖収量および全乾物重もサンネッカE区が対照区よりそれぞれ13-24%、19-31%および14-20%増加した.また、原料茎収量、蔗糖収量および全乾物重の最高値は400kg/10aサンネッカE区で得られた.サンネッカE区の根系の分布は水平方向、垂直方向とも各分布域における根重密度はサンネッカE区が高かった.
