Aim: The study measured the menstrual knowledge and hygiene practices of adolescent girls of low socio income group.

Study Design: Purposive sampling method was used for the selection of study participants.

Place and Methodology: A self-developed Questionnaire was used to collect data on knowledge and hygiene practices among the adolescent girls of Hyderabad.

Results: Results showed that the levels of knowledge regarding menstrual health is low among the adolescent girls. Menstruation is clouded in social taboos and is never discussed in homes and hence the adolescent girls are ignorant about it. They accidentally discover and experience menstruation as it happens. It is a prerequisite and a right for adolescent girls to have accurate and adequate knowledge about menstruation and its appropriate related hygiene practices.  Further, there exists a positive correlation between menstrual knowledge and hygiene management by adolescent girls which clearly indicates that if the menstrual knowledge increases among adolescent girls, then there can be improvement in the hygiene practices as well by the same group.

Lilium is one of the most important cut flower and ranks second among bulbous flowers in international market. The scope of the study lies in the fact that despite having the congenial climate of Kashmir for bulb production, the cultivators are importing the bulbs from abroad, so there was need to rationalize the nutrition for optimum plant growth and bulb yield of lilies under Kashmir valley conditions. Consequently, an investigation was undertaken to evaluate the differential response of Asiatic lilies cultivars to different methods of application and nitrogen sources (urea and calcium nitrate) in terms of plant growth, bulb development and yield. Significant differences were observed in growth parameters and behaviour of two cultivars viz., Serreda and Navona. Calcium nitrate significantly improved plant height, leaf area (LA) and LA index (LAI) recorded at 50, 75, 90, and 105 days after planting (DAP). Bulb yield parameters (weight of mother bulb, weight of bulblets, number of bulbs plant-1, propagation coefficient) varied significantly between the two cultivars. Calcium nitrate significantly improved bulb weight, bulb circumference, the number of bulbs plant−1 and propagation coefficient. However, the effect of three and four split nitrogen application on plant height, LA and LAI was significant at 90-105 day interval. Ca(NO3)2 was more effective in ensuring the prompt availability of nitrogen to plants as compared to urea (NH2CONH2); also it was advantageous for improving the bulb growth because of presence of critically important micronutrient i.e. calcium. Split application of nitrogen was advantageous not only in improving the growth and yield attributes but also in preventing the significant losses of nitrogen caused by various processes such as leaching.

The present investigations were carried out on forty genotypes of jackfruit (Artocarpus heterophyllus Lam.) to determine the extent of variability present in the material and association among different traits. The genotypes were collected from six north-eastern states of India viz. Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram and Tripura during the two years 2016 and 2017. Selection and identification of superior genotypes were done following IPGRI jackfruit descriptor. The experiment was laid using randomized block design with three replications during the year 2016 and 2017 under Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, East Siang, Arunachal Pradesh. The phenotypic coefficients of variability and genotypic coefficients of variability were recorded highest values for weight of fresh flake without seed (52.69% & 50.52%, respectively), stalk length (51.09% & 49.06%, respectively) and fruit weight (48.11% & 45.86%, respectively). High heritability coupled with high genetic gain was observed for stalk length, fruit weight, weight of fresh flake with seed and weight of fresh flake without seed traits. Genetic advance was recorded highest for 100-seed weight followed by stalk length and lowest for flake/fruit ratio followed by seed width traits. Yield per plant showed significant and positive genotypic correlation coefficient with fruit diameter, rachis diameter, fruit weight, petiole length, fruit length and flake length traits. The path coefficient analysis revealed that weight of fresh flake with seed has maximum positive direct effect on fruit yield per tree followed by weight of flakes per kg of fruit.

Arsenic is a potential contaminant of groundwater as well as soil in many regions of the world. Elevated soil arsenic levels resulting from long-term use of arsenic contaminated ground water for irrigation may inhibit seed germination and seedling establishment of rice, the country’s main food crop. An experiment was conducted to study the effect of different forms of arsenic on growth and photosynthetic pigments of rice plants. For this purpose rice seedlings were grown hydroponically with half strength of modified Hoagland nutrient solution toxified with different doses of arsenate and arsenite namely 0, 5, 10, 15 and 20 ppm. Germination percent of rice seeds and photosynthetic pigment content of rice seedling decreased significantly with increase in concentration of arsenic of both the forms. Growth parameters affected more seriously in arsenite treated plants than arsenate treated plants.

Picrorhiza kurroa plants were collected from its natural habitat. In vitro plants were raised from the leaves of high yielding collection screened in an earlier study. Leaves, roots and internodal segments were cultured for 15 days. The effect of thidiazuron (1-phenyl-3-(1, 2, 3- thiadiazol-5-yl) urea; TDZ) pretreatment for 15 days on regeneration potential of different explants viz. leaves, roots and internodes of Picrorhiza kurroa was studied. Regeneration potential varied significantly with the type of explant. Regeneration response of 100% with 46.25 shoots per explant was obtained in leaf segments of 2.0 cm length pretreated with 0.5 µM TDZ for 15 days and then transferred to 2.32 µM kinetin (Kn) containing MS basal medium. In case of root explants maximum shoot number (17.12) was obtained on 0.5 µM TDZ pretreated for 15 days and then to 3.64 µM Kn. Maximum shoots per explants (12.33) were obtained in case of internodes pretreated with 0.5 µM TDZ for 15 days and transferred to 1.16 µM Kn. Regenerated shoots from different explants developed in vitro rooting on MS basal medium within 7-8 days. Conclusively, an efficient and repeatable protocol for rapid regeneration from different explants and in vitro rooting has been developed in P. kurroa which can be effectively used for its conservation.

Aim: To advance the creation of variety through food product development and innovation, a comparative study of custard products with Turmeric (Curcuma longa) and Pawpaw (Carica papaya) was done.

Study Design: This study was made to fit into a one way Analysis of Variance.

Place and Duration of Study: The research was carried out at the Department of Food Science and Technology laboratory, Federal University of Technology, Owerri, Nigeria, between March 2017 and August 2018.

Methodology: Different ratios of corn starch to pawpaw or turmeric were used in the custard product while a commercial custard product was used as the control. The samples were evaluated for proximate composition, microbiological analysis, functional and sensory properties.

Results: The water absorption capacity (1.44% to 1.64%), swelling index (5.27% to 6.77%), bulk density (0.68% to 1.55%) and gelation concentration (6.47% to 8.62%) of the turmeric treated custard and pawpaw treated custard were significantly different (P<0.05) from the control sample. The pawpaw treated custard had a higher protein and ash content compared to turmeric treated custard and control. With regards to the general acceptability of the custard products, the control was much accepted while the pawpaw sample was moderately accepted by the panellist. Microbial result showed that the pawpaw treated custard had an acceptable level of Streptococcus spp. The contamination level in the pawpaw treated custard, turmeric treated custard and the control were below the safety level recommended by International Microbiology Standard Limits for pseudomonas spp.

Conclusion: The development of these custard products showed that pawpaw treated custard is acceptable and may compete favourably in the market since it has better aroma than some commercial custard present in Nigeria. It is also important to pay close attention to the handling and processing of these products so as to promote food product safety.

The climate change poses a great challenge to the agriculture sector compared to any other sector in the country as it is highly a weather dependent enterprise. The study results reveal that the climatic variation such as the occurrence of drought due to irregular distribution, lesser rainfall have a high level of impact on the dryland farming by adversely affecting the yield levels of the crops. The farmer’s perception of the impact of climate change on the crops grown in Rainfed condition, such as yield reduction and reduction in net revenue. The farmers already act to the changes in the climatic changes both by adopting the technological coping mechanisms on the positive side and negatively through shifting to other professions especially more pronounced in dryland farming regions of the country. It is concluded that the small and medium Rainfed farmers were highly vulnerable to climate change and to a larger extent the small and medium Rainfed farmers adopted coping mechanisms for climate change compared to large farmers. The studies suggest that as the impact of climate change is intensifying day by day, it should be addressed through developing appropriate mitigation strategies and supported through policy perspective at the earliest to avoid short-term effects such as yield and income loss and long-term effects such as quitting agricultural profession by the dryland farmers of the country.
