An experiment was conduced to study the effects of a mixture of charco
al with pyroligneous acid (charcoal 4 :pyroligneous acid 1; Sannekka E
) on dry matter production and root growth of summer planted sugarcane
. Sugarcane variety NCo 310 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 replicati
ons. Yield contributing characters, such as stalk number, stalk length
, stalk diameter and sugar content in stalks were increased by applica
tion 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 ca
ne 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 co
ntrols. The highest cane stalk yield (11.4 kg m(-2)), sugar yield (1.9
5 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.
