Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinological disorders with a broad spectrum of clinical manifestations affecting about 6-8% women of reproductive age. Many adolescent girls and women lack knowledge of Polycystic ovarian syndrome. The present study was designed so as to evaluate the knowledge of sixty undergraduate girl students from College of Community Science, Saifabad, Hyderabad, PJTSAU before and after the intervention programme on Polycystic ovarian syndrome. Knowledge assessment schedule developed by Kalpana, [1] was used with modifications as a data collection tool. High levels of knowledge was observed to be on basic terminology and definitions (31.6%),  pathophysiology of the disease (16.6%), complications of Polycystic ovarian syndrome (21.6%),  and management of Polycystic ovarian syndrome (26.6%) before the educational programme. An educational programme was provided as intervention to improve the students’ knowledge level regarding Polycystic ovarian syndrome. Then, a post test was conducted to measure the effectiveness of the intervention. The knowledge level of 83.3%, 68.3%, 75% and 83.3% of the total sample was found to be high on basic terminology and definitions, pathophysiology, complications and management of Polycystic ovarian syndrome respectively. Mean scores of the post-test were significantly higher compared to their values at pre-test (p<0.001). Thus the results prove that the knowledge intervention in the form of educational programme is effective in enhancing the knowledge of the students.

Pearl millet is a climate-resilient crop which is most widely grown in the arid and semi-arid tropics of Asia and Africa over 26 mha. It is a highly nutritious cereal crop and rightly termed as nutricereal. This crop requires low inputs and delivers high cost-effective benefits. Development of high yielding hybrids is the major target of pearl millet researchers globally. The understanding of genetic diversity is very important and must for developing superior hybrids and crop improvement programs. In the present study, we evaluated the diversity among 30 different released hybrids and varieties of pearl millet using 125 Simple Sequence Repeat (SSR) markers. Out of these, 61 polymorphic SSRs were reported giving 191 alleles with an average of 3.13 alleles per primer. Polymorphic Information Content (PIC) varied from 0.33 to 0.76 with an average of 0.55 PIC value. The cluster analysis based on these SSR markers categorized the genotypes into four major clusters viz., I, II, III, IV with similarity coefficient ranging from 0.58 to 0.73. The results depicted that sufficient genetic variability exists among the different hybrids and varieties used in the study which can further prove useful for pearl millet improvement programs. The study also reveals that SSR markers are proficient and may be used efficiently for genetic diversity studies in pearl millet. It is also anticipated that findings of this study may be further used for DNA fingerprinting and varietal identification.

NRSC-CN for surface runoff estimation is one of the most widely used methods. GIS and remote sensing techniques facilitate accurate estimation of surface runoff from an area. Water availability estimation can be understand by rainfall and runoff is essential. Runoff generated by rainfall is not only dependent on the intensity, duration and the distribution of rainfall, but also soil type, vegetation, and land-use types have significant effects on the runoff pattern. The present study aims to estimate runoff in a study area. The study was carried out in Godavari Eastern Delta in Andhra Pradesh, India. The land use/land cover map, soil map was prepared. The soil and land use map has been prepared by the information available at Andhra Pradesh space application centre. For the rectification of reference, soil and land use map of the study area ERDAS IMAGINE-8.4 software was used. For 30 years surface runoff was estimated, as the runoff value depends on the rainfall, trend of runoff was found to be highly dependable on the quantity of rainfall received within the entire study area. The yearly trend of rainfall during 1987 was 8.97 it’s but the other years, and therefore the runoff was also found to follow an equivalent trend. Similarly, for the year 1995, the runoff was recorded as high, which was also having the highest rainfall.

Study was conducted at the Department of Farm Machinery and Power Engineering workshop, College of Agricultural Engineering, JNKVV, Jabalpur, Madhya Pradesh to determine the nozzle spacing and boom height of JNKVV push type solar and battery operated sprayer on the basis of width of overlapping of spraying. It is difficult to obtain the consistent width of the overlapping between adjacent nozzles for the commonly used spraying. Coefficient of variation of nozzles overlapping varies according to the spray height and nozzle spacing. Precision guidance and precision sprayer control have substantial promise to reduce input application overlap, thus saving chemicals, fuel, and time during the application process. It was found that the overlapping increases with increase in height of the boom. The results were obtained by the overlapping test for boom height and nozzle spacing, there was no overlapping obtained up to height of 80 cm. The overlapping varied from 39 cm to 43 cm and mean overlapping was 41.3 cm at nozzle height 120 cm and nozzle spacing of 60 cm. An average overlapping of nozzles varies from 29 cm to 34 cm at nozzle spacing of 70 cm and boom height of 120 cm. At the boom height of 160 cm and nozzle space of 70 cm, spray overlap fluctuates from 79 to 85 cm. The overlapping at nozzle space 80 cm varies from 19 to 22 cm and mean overlapping was 22 cm at the boom height of 120 cm and nozzle space 80 cm. The overlapping varies from 70 cm to 74 cm in nozzle series at the boom height of 160 cm and nozzle space 80 cm. As per the crop cultivation practices, adjusted the boom height and spacing to reduce overlapping of spraying.

DOI: 10.9734/cjast/2020/v39i3130988

Household cleaning products are commonly used worldwide to enhance cleanliness and hygiene. Most household cleaning products marketed commercially today are very expensive, unaffordable and contain toxic and harmful chemicals. Some may even damage the cleaned surface through corrosion or abrasion. The aim of this study was to produce eco-friendly household cleaning products from locally available materials. The study was carried out in Omuku, Rivers State. The population was made up of all 182 housekeepers and working mothers across the five school of the Federal College (Technical) of Education and 15 hotels. The stratified random sampling technique was used to sample 102 working mothers and housekeepers. Household cleaning products such as liquid soap was produced from local materials such as orange, lemon, tangerine, coconut oil, and palm ash. Toilet cleaner was formulated from ginger and aloe vera extracts and activated carbon while floor wash was made from local gin, liquid wash, alcohol, lemon and sodium chloride. The products were subjected to sensory acceptability. A nine Point Hedonic Scale questionnaire was also constructed and administered to the respondents for data collection. Mean rating was used to analyze the research questions and sensory evaluation and Z-test was used to analyze the hypotheses at 0.05 level of significance. The result of the study revealed that the locally produced household cleaners were acceptable in terms of quality. The respondents’ response differed with respect to the colour and the odour of locally made household cleaners especially the locally produced liquid soap. The study also revealed that the locally produced household cleaners differed from commercial ones only in terms of colour. The result therefore indicates the potentials of utilizing locally available materials for the production of non-toxic, natural and environmentally safe household cleaning products.
