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). |
