Rainfall probability analysis improves predictions of the minimum assured rainfall to aid crop planning. An attempt has been made to look into the patterns of rainfall distribution, including weekly, seasonal, and annual rainfall, using data collected from the Fingeshwar tehsil of the Gariyaband district, Chhattisgarh, over a ten-year period (2011-2020). Using the Weibull plotting position function, expected weekly, monthly, seasonal, and yearly rainfall values were calculated for various probability levels. Based on a 10-year yearly average, the data revealed that 1074.4 mm of rain were actually seen, following an average of 52.2 rainy days. A rainfall amount with a 75% probability level predicts 862.9 mm annually. The largest amount of weekly rainfall, 49 mm, was predicted to fall in the 35th week, followed by 32.1 mm in the 25th standard week and the least amount, 0.0 mm, in the 20-22nd, 29, 37, 40-42nd SMW. This prediction was made at a 75% chance level, same like the one before. According to a study of monthly rainfall at 70, 75, and 80% probability levels, the three crucial wet months are July, August, and September, with probabilities of getting a monthly rainfall between 0 and 50 mm. At a 70% probability level, the seasonal rainfall report projects 833 mm for the Kharif season. Thus, it can conclude that the kharif season's activities could start between the 22nd and the 23rd standard week and farmers can properly produce paddy crops in highland areas followed by any rabi crop in rabi season.

The application of fertilizers can be optimized to maintain crop yield while reducing the amount of fertilizer input. One way to achieve this is by using soil fertility maps and fertilizer recommendations to regulate fertilizer application. In this study, statistical techniques were employed to analyze the physical-chemical quality of soils in the Gwalior region of Madhya Pradesh. The study involved collecting 95 soil samples (0-15 cm) from four blocks in the Gwalior area using GPS (Bhitarwar, Morar, Ghatigao, and Dabra), and conducting laboratory analyses. The results of the analysis showed that the pH, EC, and OC of the soil samples ranged from 7.10 to 8.90, 0.21 to 0.83 dS/m, and 0.23 to 0.98%, respectively. The soil samples also had varying levels of N, P, and K, with values ranging from 194 to 336, 6.10 to 45.00, and 69.89 to 751.30 kg/ha, respectively.

The present study was conducted to determine the response of 55 double haploid (DH) rice lines developed for drought tolerance from the cross Swarna × IR159B in polyethylene glycol (PEG) induced drought stress under in-vitro conditions (DH lines named as double haploid rice lines-DRL). Drought stress was created using PEG-6000 at different level of external water potential. Analyzed seedling traits of DRLs showed significant differences in response to different PEG concentrations. A decrement in plant growth at seedling stage with the increase in PEG concentration was observed as expected. Among 55DRLs, 14 DRLs were found to be drought tolerant sustaining the stress level till -7.5 bar as of the tolerant checks. Further, Drought linked SSRs were also evaluated in developed rice lines. Out of 8 SSRs, RM55 (R2 value- 13.5%) and RM259 (R2 value- 13.9%) found to be exhibiting significant association with the shoot/root ratio at - 7.5 bar stress level. Out of 14 DRLs, 9 DRLs were found to be showing drought tolerant in phenotypic and genotypic screening. Hence, PEG induced stress screening method used in this study will serve as the baseline for screening of rice lines for drought tolerance at very early stage without exploitation of much resource.

A field experiment was undertaken at College of Agriculture, Vellayani during June to December 2019, to assess the efficacy of liquid consortium biofertilizer, Plant Growth Promoting Rhizobacteria (PGPR) Mix - I in cassava and to examine the changes in soil chemical and biological properties with the application. The treatment combinations included four levels of biofertilizer [PGPR Mix - I liquid (L) @ 2 %, PGPR Mix - I liquid (L) @ 5 %, PGPR Mix - I powder (P) formulation @ 10g of 2 % mixture per plant, without biofertilizer] and three levels of nutrients, with 50: 50: 100 kg NPK/ha as the standard dose of nutrients (SDN), [50 % SDN, 75 % SDN, 100 % SDN]. The 4 × 3 factorial experiment was laid out in randomized block design with three replications. The results of the study revealed that the liquid biofertilizer consortium at 5 per cent + 75 percent SDN (37.5: 37.5: 75 kg NPK /ha) recorded significantly superior yield attributes in cassava and improved the soil organic C, available K status and microbial count.

Presence of plastics in the surroundings is ubiquitous, as generation of plastics is booming globally and it gets accumulated in oceans leading to deleterious impacts on marine life, public health and the surrounding environment. Owing to its non-degradable nature, plastic particles remain in surroundings for extended periods which automatically facilitate its out spreading. Therefore, there is a need to shift to bio-based plastics, as bio-based green economy hinges on sustainable employment of bioresources for generating a broad spectrum of products, biofuels, chemicals and bioplastics. Typically bioplastics are synthesized from bio-based resources considered to contribute more to sustainable production of plastic as a part of the circular economy. Bioplastics are luring attention and growing as counterfeit material for petroleum-derived plastics owing to their biodegradability. Recently an engrossed interest has been burgeoning in producing drop-in polymers and new-fangled bioplastics by utilizing lignocellulosic feedstock. This paper reviews the enormous potential of lignocellulosic feedstock as a significant inedible substrate for bioplastic synthesis. Polyhydroxyalkanoates, polyurethanes, polylactic acid and starch-bioplastic are prevailing bio-based plastic comparably derived from lignocellulosic biomass. In forthcoming years bioplastic derived years’ bioplastic derived from lignocellulose will loom as valuable material in numerous fields for an extensive range of cutting-edge applications.

The main polluting source of heavy metal contamination of water is the leather tanning industry, which uses chrome powder and discharges it into the nearby ecosystem. In this investigation, chromium-resistant bacterial strains were isolated and characterized from tannery effluent. Based on morphological and biochemical characterization, the predominant sporulating Bacillus sp. was isolated and identified as Bacillus subtilis based on 16S rRNA gene sequencing. Chromium degradation by the bacterial strain was evaluated using the flask culture method at three different concentrations (300, 600, and 900 µg/ml) of Cr (VI), and the reduction potential of the isolated bacterium was analyzed by Atomic Absorption Spectrophotometry. A maximum reduction of approximately 78% was found at 24 hrs of incubation at pH 7 and at a constant temperature of 30°C. More than 50% of the Cr(VI) was decreased in 24 hours when the Cr(VI) concentration varied from 300 to 900 g/ml. FTIR analysis showed the involvement of hydroxyl and amine groups in chromium adsorption. As an outcome, this strain could be a promising bioagent for the environmentally friendly elimination of toxic Cr(VI) from polluted environments.

Soil carbon pools have a significant impact on the global carbon cycle and soil erosion caused by natural or human activities is one of the main drivers of changes in soil carbon sequestration. The present study aimed to estimate the carbon loss associated with soil loss in the watershed using remote sensing and GIS techniques. The study was carried out at the Central MPKV Campus Watershed, Rahuri, located in the rain shadow region of the Maharashtra state, India. The soil loss from the watershed was estimated using USLE model. The soil loss and carbon loss from the watershed were estimated before the implementation of conservation measures and after the implementation of conservation measures. It was found that the average annual soil loss from the watershed before and after conservation measures was 18.68 t/ha/yr and 9.41 t/ha/yr, respectively. Carbon loss was determined by soil loss rate, organic carbon content and the carbon enrichment ratio. The carbon loss from the watershed before and after conservation measures was 348.71 kgC/ha/yr and 205.52 kgC/ha/yr. The findings revealed that soil and carbon erosion was very severe on steep slopes without conservation measures and with limited vegetation cover. It was found that by reducing the carbon loss associated with soil loss, soil conservation measures not only aid in the conservation of natural resources but also serve as a climate change mitigation measure.

Advent of industrialization increased the human population significantly and it expanded very rapidly from nineteen sixties. Introduction of mechanization, chemical fertilization and genetic selection in agriculture increased the food production, reduced pestilence and thus improved life expectancy. However, in doing so the natural resources were over utilized, degraded and polluted. The greenhouse gas emissions from anthropogenic activities increased several folds that resulted into global warming, the consequences of which are being observed in the form of floods, draughts, cloud bursts, melting of glaciers, rising of sea level and loss of species. The soil fertility & water table is decreasing, resistance to pesticides, drugs, antibiotics is increasing and immergence & reemergence of diseases are common. Since the world population by 2050 is anticipated to touch 9 billion that means an increase of 30%. Obviously, the demand for food to feed such a huge population would require 70% increase in the food. With limited resources, depleted soil, polluted atmosphere, disturbed ecosystems and exhausted natural resources, the challenges for food security have amplified. Urbanization, improved incomes and dietary changes will increase the demand for food of animal origin in coming years. Globally animal products provide 67% of the protein and the requirement for meat and milk by 2050 is expected to increase by 73% and 58% respectively. Therefore, to ensure food and nutritional security in coming years, livestock production has to be augmented efficiently, smartly and sustainably. As such, precision, smart livestock farming is inevitable that must integrate all the techniques, skills, knowledge and innovations to produce safe, sufficient, affordable, accessible and sustainable animal food with minimum environmental impacts. With the advancement in robotics, biosensors, artificial intelligence, internet of things and information technology, the farming practices should now be technology driven, smart, need based, automated, productive and integrated.

A field experiment was undertaken in the post-Rabi season of 2019-2020 to reveal the response of greengram (Vigna radiata L.) to seed dressing and seed priming with nano molybdenum trioxide (MoO3). The experiment was laid out in randomized block design (RBD) consisting of 10 different treatments i.e., M0 (no seed treatment with Mo); M1 (seed dressing with Sodium molybdate @ 400 ppm); M2, M3, M4, and M5 (seed dressing with nano Molybdenum trioxide-MoO3 @ 50, 100, 200 and 400 ppm, respectively); and M6, M7, M8 and M9 (seed priming with nano MoO3 @ 50, 100, 200 and 400 ppm, respectively). Inoculation of greengram seeds cv. Shreya (IPM 2-14) with Rhizobium sps. was undertaken in all treatments as per the recommended practice, except in M0 (control). The MoO3 nanoparticles (NPs) synthesized from Ammonium molybdate through calcination at 600 0C for 5 hours indicated globular-shaped NPs of 68.55 nm in TEM and XRD. Nanopriming with MoO3 @ 200 ppm (M8) was most promising in recording significantly superior growth and yield attributing parameters and yield, whereas Mo (control) produced the least. Crop height, number of branches, root length, shoot dry matter, pods/plant and seeds/plant and root nodulation at harvest in M8 were 39.4% and 22.6%; 39% and 5.6%; 23% and 9.3%; 43.9%, and 16.3%; 28.2% and 5.3%; 28.1% and 0.8%, and 73.3% and 36.5% higher than M0 (control) and M1 (farmers’ practice), respectively. Superior growth and yield attributing characters in M8 treatment produced the highest grain and stover yield of 0.88 and 3.74 t/ ha that was 32.53% and 8.37%, and 35.5% and 14.7% higher than M0 (control) and M1 (farmers’ practice), respectively. Seed priming with nano MoO3 @ 400 ppm (M9) and seed dressing with nano MoO3 @ 400 ppm (M5) were of second and third order in recording grain and stover yield but M0 recorded the lowest among all the treatments.

The experiment was laid out in randomized block design (RBD) consisting of 10 different treatments i.e., M0 (no seed treatment with Mo); M1 (seed dressing with Sodium molybdate @ 400 ppm); M2, M3, M4, and M5 (seed dressing with nano Molybdenum trioxide-MoO3 @ 50, 100, 200 and 400 ppm, respectively); and M6, M7, M8 and M9 (seed priming with nano MoO3 @ 50, 100, 200 and 400 ppm, respectively). Inoculation of greengram seeds cv. Shreya (IPM 2-14) with Rhizobium sps. was undertaken in all treatments as per the recommended practice, except in M0 (control). The MoO3 nanoparticles (NPs) synthesized from Ammonium molybdate through calcination at 600 0C for 5 hours indicated globular-shaped NPs of 68.55 nm in TEM and XRD. Nanopriming with MoO3 @ 200 ppm (M8) was most promising in recording significantly superior growth and yield attributing parameters and yield, whereas Mo (control) produced the least. Crop height, number of branches, root length, shoot dry matter, pods/plant and seeds/plant and root nodulation at harvest in M8 were 39.4% and 22.6%; 39% and 5.6%; 23% and 9.3%; 43.9%, and 16.3%; 28.2% and 5.3%; 28.1% and 0.8%, and 73.3% and 36.5% higher than M0 (control) and M1 (farmers’ practice), respectively. Superior growth and yield attributing characters in M8 treatment produced the highest grain and stover yield of 0.88 and 3.74 t/ ha that was 32.53% and 8.37%, and 35.5% and 14.7% higher than M0 (control) and M1 (farmers’ practice), respectively. Seed priming with nano MoO3 @ 400 ppm (M9) and seed dressing with nano MoO3 @ 400 ppm (M5) were of second and third order in recording grain and stover yield but M0 recorded the lowest among all the treatments.","PeriodicalId":12035,"journal":{"name":"Environment Conservation Journal","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139350413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wild species constitute a source of valuable genes for many adverse climatic conditions, disease and pests. To match up the level of quick depleting insect pest and disease resistance and fast evolving pests, it is the urge of the hour to broaden the resistance base. In order to achieve this goal in cotton, wide hybridization was performed between G. hirsutum (AADD) cv. MCU5, CO14 and CO17, and G. armourianum and interspecific hybrids developed were characterized for several morphological characters for obtaining an idea about the status of the various traits. Interspecific hybrid developed with all three G. hirsutum varieties are potential lines for future introgression programs of insect and disease resistance along with other useful traits. The F1 hybrid displayed intermediate expression for most of the traits. Traits like colour of the stem, leaf colour, position of stigma, nectarines of hybrid completely resembled wild parent-and are considered as dominant in expression. The petal spot was present in the hybrid similar to that wild parent, unlike the cultivated parent; this appeared with different levels of intensity in F1 along with other characters like colour of the anther, and filament colour. Hybrids had profuse flowering throughout the year with low pollen load and pollen of variable shape and size expressing sterility to partial fertility. Noteworthy differentiation was seen between the leaf size and size of other plant parts of the hybrid.
野生物种是许多不利气候条件、病虫害的宝贵基因来源。为了与快速衰退的病虫害抗性和快速演变的害虫相匹配，当务之急是扩大抗性基础。为了在棉花上实现这一目标，在 G. hirsutum（AADD）变种 MCU5、CO14 和 CO14 之间进行了广泛杂交。MCU5、CO14 和 CO17 与 G. armourianum 之间进行了广泛杂交，并对培育出的种间杂交种的多个形态特征进行了鉴定，以了解各种性状的状况。与所有三个 G. hirsutum 品种培育的种间杂交种是未来抗虫、抗病及其他有用性状引种计划的潜在品系。F1 代杂交种在大多数性状上表现出中间表达。杂交种的茎色、叶色、柱头位置、油桃等性状与野生亲本完全相似，被认为是显性性状。杂交种的花瓣斑点与野生亲本相似，但与栽培亲本不同；在 F1 中，花瓣斑点与花药颜色和花丝颜色等其他性状的强度不同。杂交种全年开花，花粉量少，花粉的形状和大小各不相同，表现出不育或部分不育。杂交种的叶片大小和其他植株部分的大小之间存在显著差异。
