Abstract
This paper explains the spatial and temporal variations of Teak (Techtonagrandis), panel data of eight districts viz, Cuddalore, Pudhukottai, Tanjavore, Trichy Tiruvarur, Nagapattinam, Ariyalur and Karur were used for the period of 24 years from 1996-97 to 2019-20. It was found that Teak area as a dependent variable and twelve independent variables like Barren unculturable, Other fallow, Culturable waste, Current fallow, Cropping Intensity, Total Food crops, Total Nonfood crops, Gross Area Irrigated, Total Rainfall, Price of Teak, Net Area Sown, Gross Area Sown are used for the analysis. The results showed that the coefficient of determination (R2) value was 46 percent within the model, 64.95 percent between the model and 54.89 percent for the overall model. The values of the model define that 46 percent of the variation in the area of teak is influenced by the explanatory variables within the model. In main effect, the area of teak is spatially and temporally significant, positively simulated for the price of teak with a 1 percent level of significance. Total rainfall is negative with 1 percent level of significance. In the spatial-panel lag model, the estimate of the parameter ρ was significant at one percent. The theta value is significant at a one percent level of significance. In direct effect, total rainfall shows a negative effect at a significance of one percent and the price of teak also shows that a positive effect at the five percent level of significance. In indirect effect rainfall shows positively significant at 5%, price of teak contributes negatively at 5% significance. The total effect of the model showed the negative effect of the total rainfall at one percent level of significance and the price of teak showed that a positive effect at five percent.The area of Teak expansion was influenced by two major factors like total rainfall and the price of teak. Among these, Rainfall is negatively related and the price of Teak was positively related with the area of Teak.

Introduction The cyclonic disturbances over the Bay of Bengal(BoB) are formed either in situ or remnants of the cyclones receiver from the China Sea. The pre (Mar to May) and post-monsoon periods (Oct to Dec) of the year favor cyclonic disturbance (CD) formation over the Bay of Bengal (BoB). The north Indian Ocean (NIO) fabric […]
Abstract
Background: Recurrent tropical cyclones of thermal origin in the Bay of Bengal have consistent impairment to the 480km Odishacoasts of the east coast of India. The ascribing causes are fierce wind, torrential rain, and storm surge inundations. The sea surface temperature (>270C), relative humidity, wind shear, Coriolis force, cyclonic disturbances, warm oceanic current, easterly trade wind, Indian Ocean Dipole, and upper air cyclonic circulation. Odisha receives a lion’s share of the slams of cyclones of the Bay of Bengal which is shattering its coastal inhabitants and the ecosystem.
Methodology and Results: The cyclone data of the India Meteorological Department from 1891 to 2022are analyzed statistically. The categorization, naming, and cause of slam of cyclonic disturbances in the Bay of Bengal particularly along the Odisha coast are debated in the present study. The favorable geological stratification, meteorological players, and coastal features of the Odisha coast are discussed. The trends in landfall of various types of cyclones and the storms that shall brew and grow over BoB fabric from 1980 to 2020 have been using a machine-learning model.
Conclusions: There is a decrease in cyclogenesis frequency but an increase in amplitude, intensity, and severity is the present trend along with a southerly shift of landfall along the east coast. The changes in the coastal corridor, the discrete Eastern Ghats belt, and its seaward retro gradation are the reason that the southwest monsoon brings with it high wind shear, which has allowed the cyclones to slam the Odisha coast instead of the Gangetic coast and Godavari region.

Introduction A heterogeneous group of small-seeded cereal crops known for their small coarse grains is called millets [14]. Millets had a vital role in strengthening food security [8] due to their ability to withstand extreme climatic conditions, pH, the salinity of the soil, in a short cultivation period [12]. Energy bars were originally designed for […]
Abstract
Millets are small coarse grains with high nutritive value. Snacks play a major role in diet of Indian population. Hence the study was targeted to underweight adolescent girls from 13 to 16 years of age. The millet bar of 50gms was given for 90 days along with the normal diet to 20 adolescent girls. The weight and height were monitored with 30 days interval gap till 90 days. The study concluded that there was a significant increase in BMI at 1% level of significance. The weight was increased and t calculated value is greater than t tab value. Hence supplementation of millet bar is highly significant.

Introduction Damming the rivers decreases flow velocities, and enhances sedimentation, resulting in larger materials deposited at the tail end, finer clay, and silt near the dam’s toe. Sediment may clog vents of excluders and turbines disrupting dam activities [1], [2]. Hirakud reservoir was first impounded in 1957, behind the longest composite dam across the Mahanadi […]
Abstract
Hirakud reservoir impounded since 1957, across the Mahanadi River, Odisha, India. The River 851 km long has discharged a maximum 44.78Kcumec of the floods that inundated downstream areas, and 9500km2 of its delta region. The Hirakud reservoir commands assured irrigation to 2669 km2 and hydropower installations of a capacity of 347.5 MW of Odisha. But the dam traps about 79% of sediment received from upstream. Sedimentation, basin mismanagement, and numerous hydraulic structures have deteriorated the morphology and sediment status of the reservoir. Web-based GIS, LANDSAT, and Multi-date RS data in the web platform help in building various digital maps for meeting utilities. Present studies have utilized SRTM data for index and stream order maps and different LANDSAT data for achieving stream order, contour, aspect, and water spread area maps to quantify sedimentation in the Hirakud reservoir. Continuous sedimentation of the Hirakud reservoir has lost its 34% live storage capacity since 1957, causing the delta to sink, shrink, and subside. The diminution of storage, erratic basin rainfall, and occasional high floods caused by dams upstream have warranted fixing new zero level, and reallocation of revised storage for future capacity building. The sediment accrued within the reservoir bed if not cleared, the reservoir capacity and its benefits shall diminish. The basin managers should outwit further sedimentation by e-flow assessment and database preparations by confirming to EIA recommendations/ clearance process.

Introduction Aonla or Indian gooseberry (Emblica officinalis Gaertn. Syn. Phyllanthusemblica) is one of the important indigenous fruits of the Indian subcontinent, known for its medicinal and therapeutic properties and considered a wonder fruit for the health-conscious population. It has been grown and known in India for last more than 3500 years. It finds a special […]
Abstract
A field experiment was conducted during the year 2018-19 and 2019-2020 to evaluate the effect of integrated nutrient management on economic return for aonla production. The experiment was statistically laid out in Randomized Block Design with 13 treatments which were replicated three times. The treatments vizT1:100% RDF (1:0.5:1+ 10kg per plant),T2:75% RDF+10kgVermicompost,T3:75 % RDF+10kg Vermicompost+ 250g Azotobacter+ 250gPSB, T4 :75 % RDF+20kg Vermicompost,T5:75% RDF + 20kg Vermicompost + 250g Azotobacter +250g PSB,T6:75% RDF + 30kg Vermicompost, T7: 75% RDF + 30 kg Vermicompost+ 250g Azotobacter+250g PSB,T8 :50%RDF + 10kg Vermicompost,T9 : 50 % RDF + 10kg Vermicompost+ 250g Azotobacter+ 250 g PSB,T10:50 % RDF + 20kg Vermicompost,T1:50 % RDF + 20kg Vermicompost+ 250g Azotobacter+ 250g PSB,T12 :50% RDF + 30kg Vermicompost, T13:.50% RDF+ 30 kg Vermicompost+250g Azotobacter+ 250g PSB. The soil application of different organic manure and inorganic fertilizer were found significantly superior for better quality yield which could be a cause of maximum economic return. The maximum yield attributing characters were noted under the treatment T7: 75% RDF + 30 kg Vermicompost+ 250g Azotobacter+250g PSB. Maximum yield gives maximum return and maximum economic return was noted under the same treatment T7. The treatment T1 which comprises 100 % RDF (1:0.5:1: N: P: K + 10kg FYM plant -1) resulted in the lowest yield which was the cause of minimum economic return during both the year of experimentation i.e. 2018-19 and 2019-20.

Introduction The sustainability of rice-based cropping systems is a prime concern for Asia to maintain food security and to support economic growth. But continuous cultivation of rice is lowering soil fertility and organic matter depleting groundwater resources in tube well-irrigated areas and exacerbating weed, diseases, and pest problems. It has been suggested that if these […]
Abstract
As a staple food, rice plays a central role in the food security and economic growth of India. Rice cultivation was mostly adopted in India because of the climatic condition suitable for the crop, which uses large quantities of locally available noncommercial energy, such as manure and animal energy, and commercial energy directly and indirectly in the form of seed, diesel, electricity, fertilizer, plant protection chemicals, irrigation water, machinery, etc. Under this investigation, the mean system yield (10466 kg ha-1), production efficiency (43.9 kg REY ha-1 day-1), energy use efficiency (12.08), energy efficiency ratio (5.13), energy productivity (0.35 kg REY MJ-1), energy profitability (11.08) was highest in early planting (10 July) than 15 days delay in planting. The STBFR+GM treated plot recorded mean energy use efficiency of 11.77, energy efficiency ratio of 5.05, energy productivity of 0.34 kg MJ-1, and energy profitability of 10.77 followed by STBFR+FYM and STBFR alone. STBFR+FYM resulted in higher system yield (9715 kg ha-1) and gross returns (₹ 183462 ha-1) while STBFR+GM during both the years of study resulted in gaining more net return (₹ 83490 ha-1) and B: C ratio (1.83) and production efficiency (41.4 kg REY ha-1 day-1) showing its superiority to other nutrient combinations.

Abstract
The handloom sector is one of the most important sectors contributing to the Indian economy. Despite being one of the oldest occupational works in India, there are not many advances being done in this sector and weavers continue using the age-old looms, as there are no machinery or technologies developed related to reducing the burden of weaving and weavers. Weaving includes a lot of manual labour and physical strain, and weavers are forced to work in sub-standard, congested, and unhygienic work environments. All these lead to several health and occupational problems among the weavers, but are ignored due to various reasons like being paid less wages despite heavy manual work. Most weavers are old aged but forced to continue weaving due to several family reasons. This study tried to analyse the technological and social transitions that need to happen in the handloom sector for benefitting the weavers and providing them with decent work, economic growth, good health, and well-being; along with Industry, Innovation, and Infrastructure development as these are considered to be three important goals among the various Sustainable Development Goals (SDGs). Exploratory research was done to find out the occupational health and work-related issues of weavers from two handloom clusters of Telangana state. Results highlighted that weavers face work-related health issues like lung, back, neck, and shoulder problems, allergies, chest pain, and sight problems due to their heavy, strenuous, and repetitive work. Lack of technological advancements in their working mechanisms and infrastructural and skill-building support added fuel to these existing health conditions. These findings imply that socio-technological transformation must be done in the handloom weaving sector which can help the weaving community in contributing more to their family, improve their health and well-being, and the economic growth of our country. Finding independent weavers in the locations selected for the study was the primary challenge faced by the researcher while carrying out the current study. Independent weavers are the ones who are involved in the handloom weaving work right from the procurement of raw material stage to the selling stage. The number of independent workers have been reducing in the recent times as the younger generation in the weavers’ families are not taking up weaving as their occupation and the older generation have already become old and are not being actively involved in the weaving activities due to the the several occupational problems faced. Inspite of the several challenges faced, the research inteventions were successful in motivating some of the weavers to take up the concept of ‘value addition’ in their products, so that the consumers will be motivated to buy the handloom products as they have a new appeal, which can benefit the weavers directly or indirectly and reduce their occupational problems

Abstract
Numerous studies have been conducted on the mung bean (Vigna radiata (L.) R. Wilczek), and there are a variety of data points accessible. To evaluate the crop’s potential as food, information on the entire mung bean grains’ physical, processing, and nutritional attributes was gathered. A study of the biochemical analysis on various potential genotypes of mung bean [Vigna radiata (L)] was undertaken in the laboratory of Agricultural Biochemistry and farm trial was conducted during the rabi season of 2018-19 at pulse research farm kalyanpur, C.S.A University of Agriculture and Technology, Kanpur. In mung bean varieties according to genotypes, the nutritional quality of flour and characteristics such as the overall range of variability of test weight, grain yield quintal/ha, dhal percent, percentages of husk, broken dhal, percentage loss in processing, protein, content, were found to be 26.99-60.84g, 7-13 q ha-1, 64.29-76.92 percent, 5.41-12.83 percent, 7.65-11.91 percent, 4.96-14.15 percent, and 21 The varietal trail genotypes PDM-139, KM-2320, PDM-11, and K-851 were shown to have lower husk percentages, broken percentages, and processing losses in addition to higher levels of protein and other nutritive factors. The research mentioned above demonstrates how we identify the ideal genotype for farmers in terms of nutrition and for industrialists in terms of processing. This is essential for increasing the output of nutritious crops.
