Abstract
Experiments were carried out to evaluate citronella (Cymbopogon winterianus Jowitt)
genotypes under northern dry zone of Karnataka and to assess the effect of withering on oil
recovery in citronella. The studies were carried out during the year 2013-2014 at K R C
College of Horticulture, Arabhavi and Karnataka. The field trials were laid out in a randomized
block design with nine treatments (genotypes) namely Assam, Bio-13, Ceylon Local, CIMJeeva,
Jalapallavi, Java-2, Mandakini, Manjari and Manjusha and replicated thrice. Withering
experiment was laid out in complete randomized design with seven treatments and three
replications for the promising variety Mandakini obtained in the first experiment.
Among the genotypes Mandakini recorded the highest plant height (162.70 cm),
number of tillers (178.60), petiole length (8.06 cm), fresh biomass yield per clump (2.31 kg),
maximum oil recovery (1.95%) and highest oil yield (587.05 l/ha), while highest clump
spread (E-W) (141.66 cm) was observed in Bio-13. Maximum clump spread (N-S) (148.66
cm), highest leaf length (109.96 cm) and biomass yield (36.19 t/ha) was recorded in Assam.
Maximum tiller girth (8.98 mm) and maximum leaf width (3.14 cm) was recorded in Ceylon
Local. Highest citronellal (38.18%) and geraniol (22.18%) was recorded in variety Manjusha.
Highest citronellol (14.80 %) was recorded in Jalapallavi. Among all the genotypes Assam
and Mandakini performed best under Northern dry zone of Karnataka.
With respect to withering studies, highest loss in moisture content was observed in 18
hours withered biomass (35.9 %) and highest oil recovery was observed in 12 hours (1.79 %)
withered biomass.
