SUMMARYDetermination of canopy resistance (rc) is necessary for accurate estimating hourly latent heat flux (LET), using the Penman–Monteith (PM) model for tea crop. In this study, a non-linear relationship between rc and climatic resistance (r*) was obtained for tea plants based on micro-meteorological data and LET from the end of 2014 to the beginning of 2016 in southern China. The proposed rc model was integrated to the PM method and compared with measured LET using a Bowen ratio energy balance method. The root mean square error (RMSE) and the index of agreement (d) were calculated for assessing the accuracy of the proposed rc model. RMSE and d values for rc and LET were 167.4 s m−1 and 29.7 W m−2 and 0.93 and 0.99, respectively. As compared to data from a single season, the rc sub-model based on data from different seasons was more reliable for estimating LET of tea field when integrated to the PM model.

<p>Agriculture has predominantly been observed as the activity of men with little or no interest by women hence this study was conducted in two public senior high schools in the Assin South district of the Central region of Ghana aimed to investigate gender differences in attitude towards the learning of agricultural science. A sample of 198, comprising of 188 students and 10 teachers of agricultural science took part in the survey. The research instrument used for the data collection was questionnaire which was developed by the researchers in two different forms, one for the agricultural science students and the other for the agricultural science teachers. Research findings from the study indicated that gender had no significant influence on students’ attitude towards the learning of agricultural science. Also, the attitude of female students towards agricultural science as a profession is not different from that of the male students. The study again concluded that teachers and parents play a key role influencing students to pursue related science courses. However students should be given the room to express their choice of programme to pursue at the senior high level. It must be reiterated that teachers have a major role to play in increasing and sustaining the interest of students in the study of agricultural science. The study recommends that students especially females should be encouraged, towards building a positive attitude in learning of agricultural science to take up major future roles related to the field.</p>
