Description An experiment entitled "Effect of dates of
~ransplanting and intra-row spacings on growth, herbage and
oil yield of Davana (Artemisia pallens Wall)" was conducted
at Students' Farm, College of Agriculture~ Rajendranagar,
Hyderabad during rabi 1987-88 with an object to determine the
optimum date of transplanting and the intra-row spacing to be
adopted for Davana in the sandy loam soils under the agroclimatic
conditions of Hyderabad.
The experiment was laid out in a Randomised Block
Design with factorial concept having t~ree dates of
transplanting (20th October, 20th November and 20th December)
and three intra-row spacings (15 em, 30 em and 45 em) making
nine treatments were replicated four times. An uniform
spacing of 30 em between the rows was maintained fo.r all the
treatments.
Davana plants were taller in early transplantings
and the height decreased with the delay in the date of
transplanting. Early transplanting increased the plant
height as compared to late transplantings. Similarly, closer
spacing increased the plant height. At all dates of
planting, closer spacing (30 x 15 em) increased the plant
height. Maximum number of laterals were recorded in early
transplanting (20th October) with wider spacing (30 x 45cm).
Rooth length was maximum in early dates of transplanting
(20 October) with wider spacing (30 x 45cm).
Maximum fresh and dry weights of leaves, stems and
roots per plant were recorded in early transplanting (20th
October) as compared to late trans?lantings, and also with
wider spacing (30 x 45 em).
Dry matter production per hectare was maximum in
early transplanting as compared to late transplantings.
Closer spac1ng (30 x 15 em) recorded maximum dry matter
production as compared to medium and wider spacings.
Root shoot ratio was maximum in late transplanting&
(20th December) with closer spacings (30 x 15 em).
Days taken for 50 per cent flowering and crop
duration were more in early transplanting as compared to late
transplantings. Similarly with closer spacing.
Herbage yield per hectare was maximum in early
transplanting and closer intra-row spacings. However, oil
content was not significantly influenced by dates cf
transplanting and intra-row spacings. Oil yield was maximum in early transplanting (20th
October) and closer intra-row spacing (15 em).
