“…The effective field capacity of planters depends on the operational speed [11,15]. Field test results (Table 4) show that increase in the machine operational speed resulted in an increase in field capacity of the machine at constant turmeric rhizome length, which agrees with the report of Kalay and Moses [17].…”

“…This could be as a result of decreased wheel slippage of the planter which increases its operational speed which resulted in increased effective field capacity. Researchers [11,14]; Mohamed et al [11] reported that reducing planter's wheel slippage increases its operational speed. Table 3 further illustrates that the best field capacity of the studied turmeric planter was obtained when the rhizome length of 45 mm was planted at the operational speed of 12 kmh -1 .…”

A field performance analysis of a developed prototype tractor-drawn turmeric planter is presented. The experiment was randomized in a factorial design of three planter levels of rhizome lengths (30, 45 and 60 mm) and operational speeds of 8, 10, and 12 kmh -1 . An average mass of 3 kg of wholesome turmeric rhizomes were introduced into the hopper of the planter and planted in 90 m 2 of experimental plot. During field evaluation of the machine, the effective field capacity, field efficiency, missing index, multiple index and planting depth were considered; whereas laboratory tests were conducted to evaluate the planter's seed rate, percentage rhizome bruise wheel slippage and fuel consumption. Results obtained show that the maximum seed rate was 0.283 th -1 . The maximum percent bruised turmeric rhizome was found to be 30.08%. The mean effective field capacity varied between 0.63 -0.96 hah -1 , at operational speeds of 8 and 12 kmh -1 , respectively and 45 mm rhizome length. The mean field efficiency was obtained to be 65.8%. The maximum wheel slippage of 4.37% and fuel consumption of 3.8 lha -1 were obtained at the machine speeds of 8 kmh -1 and 12 kmh -1 , respectively; whereas the minimum wheel slippage of 3.14% and fuel consumption of 2.2 lha -1 were obtained at the machine speeds of 12 kmh -1 and 8 kmh -1 , respectively for the range of the studied turmeric rhizome length. The highest and lowest percentage turmeric rhizome miss index of 35% were recorded for turmeric rhizome length of 30 mm at a speed of 10 kmh -1 and 8 kmh -1 , respectively. An average planting depth of 68 mm was obtained. The numerical optimization approach was adopted to obtain an optimal operational parameters of 12 kmh -1 speed and 45 mm turmeric rhizome grading size with an overall desirability index of 0.73. An economic evaluation was calculated using the principle of payback period which was obtained to be very small (1.64 years) compared to the life of the planter of 17 years. Prospects for future works were suggested.

The current research focuses on testing the role of creative leadership and its necessity and the extent of its contribution to the effect to achieve the empowerment of human resources in the organization independently for a sample of the leaders of the University of Baghdad, as well as diagnosing the extent of the research sample’s interest in research variables and its dimensions, as the indicative variable of creative leadership consists of five dimensions (sensitivity to problems , originality, fluency, flexibility, perseverance and risk), and the responsive variable is the empowerment of human resources from three dimensions (information sharing, knowledge possession, freedom and independence), The researcher used the questionnaire as the main means of data collection, and she employed the descriptive analytical method as a research method. The research sample included (84) individuals from the senior leaders in colleges, and the main research tool (the questionnaire) was distributed to them to survey opinions about the variables, where the research community was (91). ), the researcher distributed (91) questionnaires, and received (84) questionnaires valid for statistical analysis, and the data were analyzed using the statistical programs V24- Amos and the statistical analysis program SPSS- V24, , with the adoption of descriptive and inferential statistics methods represented by a number of statistical programs that were extracted from these programs (arithmetic mean, standard deviation, coefficient of variation, simple correlation coefficient, simple linear regression (Pearson), frequencies and percentages, Komogorove-Simirnov test, coefficient ( Alpha Cronbach), confirmatory factor analysis) to extract the results, and the researcher concluded that there is a correlation and impact of creative leadership in empowering human resources.
