RESUMEN
Micronutrient malnutrition or hidden hunger remains a major global challenge for human health and wellness. The problem results from soil micro- and macro-nutrient deficiencies combined with imbalanced fertilizer use. Micronutrient-embedded NPK (MNENPK) complex fertilizers have been developed to overcome the macro- and micro-element deficiencies to enhance the yield and nutritive value of key crop products. We investigated the effect of foliar applications of an MNENPK fertilizer containing N, P, K, Fe, Zn and B in combination with traditional basal NPK fertilizers in terms of eggplant yield, fruit nutritive quality and on soil biological properties. Applying a multi-element foliar fertilizer improved the nutritional quality of eggplant fruit, with a significant increases in the concentration of Fe (+ 26%), Zn (+ 34%), K (+ 6%), Cu (+ 24%), and Mn (+ 27%), all of which are essential for human health. Increasing supply of essential micronutrients during the plant reproductive stages increased fruit yield, as a result of improved yield parameters. The positive effect of foliar fertilizing with MNENPK on soil biological parameters (soil microbial biomass carbon, dehydrogenase, alkaline phosphatase) also demonstrated its capacity to enhance soil fertility. This study suggests that foliar fertilizing with a multi-nutrient product such as MNENPK at eggplant flowering and fruiting stages, combined with the recommended-doses of NPK fertilizers is the optimal strategy to improve the nutritional quality of eggplant fruits and increase crop yields, both of which will contribute to reduce micronutrient malnutrition and hunger globally.

Background: The United Nations defines violence against women as "any act of gender-based violence that results in, or is likely to result in, physical, sexual or mental harm or suffering to women, including threats of such acts, coercion or arbitrary deprivation of liberty, whether occurring in public or in private life".[1] Violence can take many forms, including physical, sexual or emotional and varies in its severity. Gender discrimination, norms and practices mean that adolescent girls are likely to experience certain forms of violence, such as sexual violence, at much higher rates than boys. Methods: This cross-sectional study was conducted in a rural block of North India. A total of 500 adolescent girls in the age group of 13-19 years studying in class VIII to class XII in 10 government and private senior secondary schools of the Lakhanmajra block were included in the study. A pre-designed pre-tested semi-structured interview schedule was used. Results: In this study, we found the prevalence of physical, sexual and emotional violence among adolescent girls as 6.6, 5.4 and 5.2%, respectively. The most frequent perpetrator of physical violence was the parent and of sexual violence was the neighbour followed by friends or relatives. Higher emotional violence was experienced by adolescent girls from middle-class families (P < 0.05). The prevalence of physical violence among adolescent girls was maximum in the younger age group 13-14 years (10.2%), followed by 15-17 years (4.0%). This association was found statistically significant (P < 0.05). Conclusions: There are several restrictions on free communication about violence-related topics in our highly conservative society. Blaming the victim is the rule rather than the exception and sexual abuse is usually linked to a loss of virginity and family honour in our patriarchal society. Hence, girls may be more reluctant to disclose their experience of violence.
