Randomized Block Design

The present investigation was carried out to study the effect of off season soil management practices on yield and quality of turmeric (Curcuma longa L.) cultivars. The experiment was laid out in a Factorial Randomized Block Design with ten treatments in three replications consisted of five off-season land management treatments viz., fallow (S1), summer ploughing 2 times (S2), summer ploughing 1 time (S3), solarization with transparent polyethylene film of 0.05 mm thick for 40 days (S4) and black polyethylene film for 40 days (S5). It was tested with two popular cultivars viz., Curcuma longa -1 CL-1 (V1) and Curcuma longa-2 CL-2 (V2), collected from Erode and Chidambaram. Various yield components were recorded at the time of harvest and were analysed. The yield attributing characters viz., number, length, girth and weight of mother, primary and secondary rhizomes were recorded. The treatment where solarization with transparent polyethylene film of 0.05 mm thick was tested recorded the highest yield and yield attributing characters when compared to other treatments. The same treatment also exhibited the highest fresh rhizome yield per plant, curing percentage and cured rhizome yield. The quality parameters like curcumin, oleoresin and essential oil content were also showed superior performance in the treatment where solarization with transparent polyethylene film of 0.05 mm thick was applied.

N Rates

Soil fertility decline is one of the factors that result in low productivity of turmeric (<em>Curcuma longa</em>, Zingiberaceae Lindl.,) in Ethiopia. An experiment was conducted to determine the effects of N rate and time of application on growth, yield, and quality of turmeric crops in Ethiopia. The trial consisted of five N rates: 0, 46, 69, 92, 115 kg ha<sup>−1</sup>, and five split application times: full dose at emergence, two times (1/2), three times (1/3), four times (1/4), and five times (1/5) equally split applications, arranged in a split plot design with three replications. Plant heights, tiller number per plant, pseudo-stem girth, mother and finger rhizome numbers and weights, fresh rhizome yield, oleoresin and essential oil contents – all were significantly affected by the interaction effects of N rate and time of application. The three times split application of 115 kg N ha<sup>−1</sup> produced higher values of these crop characteristics. This application rate also produced a better yield and quality than did two times of application, the most commonly used practice. Therefore, turmeric producers in southwestern Ethiopia should apply 115 kg N ha<sup>−1</sup> in three equally split applications to improve turmeric yield and quality.

Eucalyptus Sideroxylon

The main objective of this work is to determine the effect of the harvest period on the yield and chemical quality of the essential oils of the Eucalyptus sideroxylon A. Cunn. leaves of the Mamora forest, Dayet Zerzour Bnifdel region, Rabat. Essential oil yields are remarkably high above 2.3%, with an ultimate rate of 5.48% for the month of April. The chemical quality of these essential oils is characterized by the presence of two major monoterpenes, 1,8-cineole (eucalyptol) and α-terpineol, which are proportionally inverted in terms of quantity. During the wet months between September and March, the cineole predominates with levels ranging from 72.67% to 86.11% and the other dry months are characterized by an increase of α-terpineol rate from 12.05% to 25.61%. This inverted chemical variability reveals a change in the orientation of cineole and α-terpineol biosynthesis under the control of climatic factors. This work allows us to discern favorable periods for the harvest of Eucalyptus sideroxylon leaves in terms of yield and quality of essential oils.
