Self-Directed Blended Learning and Students’ Academic Achievement
(2023) Karmakar, Kritika; Bhattacharjee, Rupjyoti
Covid-19 pandemic had a marked impact on the educational system all over the world. The pandemic has exposed the students to remote learning environment and has accelerated the adoption and prominence of online education among them. It was seen that in the post-pandemic situation students started to incorporate online learning in their daily routine after the returning back from schools, which is termed as self-directed blended learning. Self-directed blended learning is an educational approach where learners take an active role in their learning process by combination of the offline and online mode. In this approach, learners have the flexibility to engage with educational content online from the comfort of their home in addition to conventional classroom learning. But this approach may have both benefits and challenges. By using stratified sampling method four Kendriya Vidyalaya schools were chosen from Balipara block of Sonitpur district, Assam. After identifying the prevalence of self-directed blended learning among students with the help of a self-constructed checklist, a sample of 224 students were selected from the highly prevalent group by the Cochran’s formula. A self-constructed questionnaire was distributed to those selected students in order to elicit information regarding their demographic characteristics, the factors influencing them to adopt the self-directed blended learning approach and the challenges of this approach. Academic records of the selected students were obtained from respective school authorities in order to assess the impact of self-directed blended learning on students’ academic achievement. The collected data were coded and analyzed using IBM SPSS software. With the help of a multiple regression analysis, it was found that factors of physical, social and intellectual dimension had a significant influence on students’ adoption of self-directed blended learning approach, with intellectual dimension being the strongest influencing factor. By calculation of composite mean it was found that among all the four chosen dimensions of challenges, physical challenge holds the highest position and with the help of correlation analysis, it was identified that self-directed blended learning has a positive impact on students’ academic achievement

Plant Density and Spatial Management of Lentil Mustard Intercropping System
(Birsa Agricultural University, Ranchi, 1998) Ramesh Singh; M. K. Singh
Production of pulses coupled with oilseeds needs to be enhanced to match the national requirement. It can be possible through Intercropping system to a considerable extent. Plant density and spatial arrangements are the two important facets of agronomic practices for minimizing the competition and maximizing yield advantages of intercropping system. Field experiment was conducted during winter season of 1995-96 on a sandy loam soil, acidic in reaction (pH 5.9), low in available N (213.24kg/ha) and medium in available P20s (37.35kg/ha) and K20 (179.0kg/ha) at the Birsa Agricultural University Farm, Ranchi to determine the compatible plant density and row arrangements of lentil mustard intercropping system for higher productivity. The treatments consisted of 9 combinations of lentil mustard inter cropping along with their respective sole cropping. The first 6 Intercrop systems were in additive series with 100 t lentil 25 and 5% mustard each grown in 3 ratio (2:1, 3:1 and 5:1) and the remaining 3 in replacement series where 33, 25 row and 17 lentil were replaced by mustard in the corresponding row ratio of 2:1, 3:1 and 5:1. The experiment was laid out in randomized block design with three replications. Intercropping of 100 % lentil 25 mustard and 832 lentil + 17 2 mustard each grown in 5:1 row ratio produced a bonus yield of mustard (424 and 324 kg/ha, respectively) without significant reduction in lentil yield (1273 and 1278 kg/ha, respectively) as compared to sole lentil (1453 kg/ha). Consequently both the systems had lentil equivalent yield 1713 and 1614 kg/ha, respectively because less competition and better compatibility leading to land equivalent ratio of of 1.27 and 1.18 and relative crowding coefficient of 4.52 and 3.08, respectively. However, Intercropping of 100 lentil 25 2 mustard grown in S:1 row ratio had significant ly higher energy use efficiency (6.12) through biomass with minimum specific energy requirement (4540 H3/tone) and maximum net return (Rs 18067/ha) and monetary advan tage (Rs 4771/ha).

Studies on Crop Geometry and Nutrient Management for Maize + Rice bean Intercropping System
(Birsa Agricultural University, Ranchi, 1997) Rajni Kiran Lakra; R. K. Bhagat
For suitable planting geometry and nutrient management in saize + ricebean interoropping, a field experiment was conducted during Kharif 1996, at Birsa Agricultural University Farm, Ranchi in a Randomised Block Design replicated thrice. The experiment consists of 19 treatment combinations of maize and ricebean where maize was taken as normal, paired and skip row planting at 100 per cent of nutrients requirement and ricebean intercropped with maize at 188, 58, 25 and zero per cent of the recommended dose of fertilizers. Results revealed that maize grown in association with ricebean in 2:3 row ratio, at 100 per cent of the recommended dose of fertilizers to both component crops, produced maximum naize grain yield (37.25 q/ha), however, it was statistically at par with maize + ricebean in 1:2 row ratio at 100 per cent of the recommended dose of nutrients to both component crops (33.19 q/ha). Maximum ricebean grain yield (12.25 q/ha) was recorded from paired row of naize alongwith ricebean in 2:3 row ratio at 100 per cent of the recommended dose of fertilizers to component crops. Maximum naize equivalent yield (51.03 q/ha) was obtained from paired row planting of maize in association with ricebean in 2:3 ratio at full dose of fertilizers to both component crops and it was significantly superior to rest of the treatments having net return of Rs. 12,367.49 ha-1 and benefit cost ratio of 1:43. Maximum energy from economical (75,014 MJ/ha) and biological yield (1,48,421 MJ/ha) was recorded from the treatments receiving 100 per cent of the recommended dose of fertilizers to both the components crops under 2:3 row ratio. But maximum energy use efficiency (11.59 from economic yield and 26.29 from biological yield) and energy productivity (788 grain gram/MJ) were recorded from sole ricebean at zero level of fertilizer. The results are in conformity with those of Mahapatra and Pradhan (1992). Maximum Land Equivalent Ratio (LER) 2.11 was recorded from maize skip row planting alongwith ricebean in 2:5 row ratio at 25 per cent of the recommended dose of nutrients to ricebean and it was on a par with all the other combinations except normal planting of maize+ ricebean in 1:2 row ratio. where ricebean received 100 or 50 per cent of the recommended dose of fertilizers. Maximum available nitrogen (277 Kg/ha) was recorded from maize + ricebean in 1:2 row ratio. where ricebean was fertilized with 50 per cent of the recommended dose of nutrients. However, maximum available phosphorus (54.23 Kg/ha) and potash (218.67 Ks/ha) were recorded from normal planted maize alongwith ricebean in 1:2 row ratio at 100 per cent of the recommended dose of fertilizers to both the component crops.

A Study on Prevalence of Social Anxiety among Students
(2023) Laldinpuii, B.; Bhattacharjee, Rupjyoti
Anxiety is a mental health condition in which the person anticipates a future worry and reacts to specific items and situations with dread and fright. Social anxiety is a persistent mental health issue characterized by unreasonable anxiety during social interactions. Everyday social encounters for those with social anxiety can result in unreasonable worry, fear, self-consciousness, and embarrassment. Symptoms can include an extreme fear of being judged, feeling embarrassed or ashamed, or worry about upsetting someone. The college time is critical for college students’ rapid maturity of cognition, emotion, and behaviour. Interpersonal communication is becoming increasingly vital in college students’ studies, lives, and employment. It is one of the most significant psychological issues influencing college students’ studies and lifestyles, and interpersonal communication issues are prevalent among today's college students. (Luan Y. et al, 2022). The objectives of the study were to find out the prevalence of social anxiety among students, to assess gender difference in the prevalence of social anxiety and to find out the impact of social anxiety on life style of the students. The study was conducted on 198 numbers of college going students who falls under the age group of 19-21 years. Two questionnaires were used for data collection. The responses were coded and analysed. The findings revealed that social anxiety was prevalent among students as about a quarter of the students (24.8%) were found to have a high level of social anxiety and 56.6 percent of the students were found to have a moderate level of social anxiety. Social anxiety has the potential to negatively impact all aspects of life, including social relationships, academic performance, emotional well-being, and future work opportunities — particularly if left unaddressed. With proper planning and understanding of its unique effects on students, educators can create an inviting environment for all students to learn and grow.

Technology Assessment for Late Sown Wheat in well - Endowed and Small Production Systems
(Birsa Agricultural University, Ranchi, 1997) Kiran Kumari; R.P. Singh "Ratan"
The finding dealt above lead to the conclusion that the study area was endowed with constrained bio-physical and socio –economic factors. Majority of the area owned by the respondents was rainfed having poor fertility status with acidic soils. Ultimately categorized into two types of production systems i.e. small production system (CDR) and well endowed production system . Majority of the respondents were illiterate relatively of middle age having cultivation as their occupation. The farming system of the respondents were complexed and diversified with the important components like crop production, vegetable production and livestock rearing, predominantly the small animals .Existing wheat production practices includes farmers wishful resource management techniques and injudicious use of chemical fertilizers as well as use of traditional non descript variety of seeds. Based upon the hypothesis that the improved seeds as well as balanced use of chemical fertilizers would lead to increased production and productivity the interventions made in the form of on farm research consisting of three treatments in small- production systems and demonstration in well endowed production system were found to be successful in testing their appropriateness as well as convincing the farmers about using the intervened technologies in their existing farming situations. Treatment (T3) i.e. improved seed +improved practices of OFR and demonstration resulted relatively higher productivity and profitability over farmers seed +farmers practices. The respondents favourably reacted to the interventions in terms of selected attributed and opined for their acceptance of treatments provided the input supply if assured timely and adequately. The woman farmers also found the interventions suitable to their multifaceted activity perspectives. The demonstration farmers received relatively higher level of knowledge than those of the participating farmers about late sown wheat production technology .On the basis of farmers assessment and opinion on refinement of late sown wheat production technology finally.

ASSESSMENT OF NUTRITIONAL STATUS OF MISING TRIBE IN ASSAM
(2023) NONGRUM, YASHMIN; Bhattacharyya, Ruma
The present investigation entitled “Assessment of Nutritional status of Mising tribe in Assam” was carried out to examine the socio-demographic profile of the Mising tribe, assess their nutritional status through various anthropometric measurements, dietary patterns, biochemical markers and clinical parameters, and implement a targeted nutrition education intervention. To achieve these objectives, a cross-sectional study design was employed and 384 households were selected for the study. Sociodemographic data was collected through structured questionnaires, while anthropometric measurements, including Height, Weight, MUAC and Body Mass Index (BMI) were recorded. Dietary assessments were conducted to evaluate the consumption patterns, assess the food and nutrient intake of the target groups. Biochemical marker, such as hemoglobin levels were measured to identify any nutritional deficiencies . Clinical examinations were performed to identify any signs of malnutrition , anemia or related health issues. The Mising tribe's socio-demographic profile reveals a majority of individuals belong to small families (65.10%) who reside in traditional Chang ghar houses (66.41%). They heavily rely on agriculture as their main income source (90.40%) and face challenges such as high illiteracy rates and lack of proper toilet facilities.The dietary assessment among the Mising tribe revealed various consumption patterns and nutritional deficiencies. The Household Dietary Diversity Score (HDDS) showed that the mean score was 6.5 out of 12, with 59.7% of households having inadequate dietary diversity. In terms of food and nutrient intake, deficits were observed in the consumption of eggs, fruits, milk and milk products, fats and oils, as well as micronutrients like vitamin A, vitamin C, and calcium. Additionally, there was a high intake of energy derived from carbohydrates whereas poor intake from fat indicating an imbalance in macronutrient distribution as per the Acceptable Macronutrient Distribution Range (AMDR). The anthropometric assessment of the Mising tribe's when compared to Indian Council of Medical Research (ICMR), National Centre for Health Statistics (NCHS), and World Health Organization (WHO) guidelines, in the case of height, both ICMR and NCHS standards were not met, indicating a significant deficit at P< 0.05 in all target age groups . Moreover, the WHO Z-scores of height-for-age classified a significant proportion of preschool boys and girls as stunted, and the mean weight of preschool boys and girls, as well as adolescent girls, were consistently lower than the ICMR and NCHS standardsfurther emphasizing the nutritional challenges faced by this population. The deficits ranged from 7.3% to 30.2% compared to the ICMR standard and from 4.8% to 43.1% compared to the NCHS standard. This suggests an overall underweight status among the Mising tribe, particularly among adolescent girls. The prevalence of undernutrition based on BMI-for-age was also notable, with percentages ranging from 14.7% to 26.08% for preschool children and from 6.5% to 40% for adolescent girls. However, overweight and obesity were not prevalent among this population. The MUAC classification indicated that the majority of preschool boys and girls were well-nourished, with only a small prevalence of acute and moderate malnutrition ranging from 6.05% to 15.15%.Various clinical manifestations associated with nutrient deficiencies.In preschool children, adolescent girls and pregnant women , clinical signs and symptoms such as dull and dry hair, pale and dry conjunctiva, cheilosis, dental caries, and dry and flaky skin were observed due to deficiencies in vitamins A, C, and iron. Anemia was also prevalent among both adolescent girls and pregnant women. The mean hemoglobin level (g/dl) of adolescent girls (13-18 years) and pregnant women of Mising tribe reported to be 10.9 g /dl and 9.3 g /dl with prevailing symptoms including pale skin, fatigue, weakness, dizziness, and rapid heartbeat. Statistical analysis revealed a strong significant positive correlation between height and micronutrient intake, including iron, calcium, vitamin C, and vitamin A (p < 0.05). This suggests that the intake of these micronutrients may have an impact on the height of the target population. Additionally, a strong significant positive correlation was found between weight and fat intake among the target age groups. Significant positive correlation was also obtained between hemoglobin level, iron intake and vitamin C. These statistical findings underscore the significant nutritional challenges faced by the Mising tribe, encompassing inadequate dietary diversity, micronutrientdeficiencies and macronutrient imbalance impact leading to stunting, underweight status, and prevalent anemia.
