Lilium mackliniae Sealy is an endemic lily of North-East India. The changing climate conditions, human activities, and natural resource exploitation have pushed the lily population to the brink of extinction. It has been well documented that the need to conserve L. mackliniae is in its critical stage. Plant phenology is closely correlated with environmental and human-caused factors. Therefore, a well-defined study of phenological traits can aid conservation aims. This paper utilized the BBCH scale to study its phenological characteristic, described by Phenological Growth Stages (PGS) in response to environmental conditions. Our findings can help the researchers as a means of conservation strategies

Chilli (Capsicum annuum L.) is the fourth major vegetable cultivated globally. The major fungal foliar pathogen causing havoc in production, export and marketing is fruit rot or anthracnose of chilli caused by Colletotrichum capsici (Syd.) Butler and Bisby which has emerged in impairing production in both tropical and subtropical regions. In the present study, new molecules of contact, systemic and combi product fungicides were tested against Colletotrichum capsici by poison food technique at different concentrations. The contact fungicides were tested at three concentrations (0.1, 0.2 and 0.3%) where, mancozeb 75% WP recorded 100 percent mycelial inhibition at all three concentrations. Among the systemic fungicides, propiconazole 25% EC and difenoconazole 25% EC showed 100 per cent mycelial inhibition at 0.025, 0.05 and 0.10 per cent. Among the combi product fungicides evaluated, metalaxyl 8% + mancozeb 64% WP showed 100 per cent inhibition which was on par with tricyclazole 18% + mancozeb 62% (99.54 %). Whereas, lowest mycelial inhibition was in zineb 75% WP (30.14 %), hexaconazole 5% EC (66.11 %) and tebuconazole 50% + trifloxystrobin 25% (72.36 %) in contact, systemic and combi fungicides respectively. The overall results suggest that the systemic fungicides of triazole group are highly effective in inhibiting mycelial growth.

The study was carried out at Regional Agricultural Research Station, Nandyal to study the performance of advance chickpea breeding lines under rainfed and irrigated conditions during Rabi 2020-21 and 2021-22 in black cotton soils. The experiment was conducted in Factorial Randomized Block Design with eight chickpea genotypes (four Desi : NBeG 49, NBeG 776, NBeG 779, NBeG 857 and four Kabuli : NBeG 440, NBeG 789, NBeG 833, NBeG 844) under rainfed and irrigated condition with gross plot size 7.2 m2 . Significantly higher seed yield was recorded in desi genotypes, i.e NBeG-857 (2592 kg/ha) followed by NBeG- 779 (2526 kg/ha) and in kabuli genotype NBeG-440 (2055 kg/ha) followed by NBeG- 833 (1874 kg/ ha). The seed yield in irrigated conditions (2326 kg/ha) was significantly higher compared to rainfed conditions (1992 kg/ha). The interactions between genotypes and irrigation was not significant. In desi genotypes hundred seed weight was higher in NBeG -779 (28.7g) and in kabuli NBeG-833 had higher seed size (44.5g). Chickpea genotypes responded to irrigation and an yield advantage of 442 kg/ha was realized due to improvement in biomass and source sink relationship.

According to Vedic Astrology, the status of the planets, their motion, and constellations associated with them have a great impact on the lives of individuals. There exists a co-relationship between celestial bodies and plants. Each of these grahas/rashis/nakshatras is associated with a specific plant that resonates with his/her birth chart. These sacred plants are used in curing any ill outcomes associated with astrology. Moreover, these plants are considered as sacred because of their medicinal, aesthetic, and natural traits. Since ancient times, our culture, food, folklore, and therapeutic practices are deeply connected and affected by the use of plants. That is why since our ancestry we revered plants like Gods and Goddesses and honored them as divine elements. These are powerful sources of many pharmacological activities like antioxidant, antimicrobial, anticancerous, etc. In Indian culture worshipping of plants, thus, form the basis for conserving many plant species. These days, there are numerous variables answerable for the depletion of biodiversity like deforestation, misuse, industrialization, unsustainable development, and so forth so, in this circumstance, the objective of this paper is to an all-encompassing perspective on the significance of plants in our day to day existence from the viewpoint of Vedic astrology, i.e., plants related with navgrah, rashi, and nakshatra alongside their cultural, socio-religious beliefs, mythological facts, and pharmacological properties. Planting and revering plants as indicated by one’s astrological chart is a significant strategy to ensure and conserve biodiversity, eventually benefiting individuals. The human relationship with flora might be useful in conserving plant species for their treasured characteristics.

Water deficiency is one of the main factors for limiting sustainable agricultural development in most arid and semi-arid regions. There is a gradual decline in the availability of fresh water to be used for irrigation in developing countries like India. Sewage farming is quite common in all urban areas in India. The effect of its direct and long-term use for irrigation needs a thorough study. However, there is increasing concern about food safety and health risks, hence, a case study was undertaken to understand the long-term effect of domestic sewage wastewater irrigation on heavy metal concentrations in soil and plants. The study reveals the mineral and heavy metal composition of irrigated domestic sewage wastewater and it has been compared with the well water irrigated in the rural area, soil parameters and also the mineral and heavy metal composition of a cultivated plant, Amaranthus tricolor L. Transfer factor (TF) was calculated to understand the extent of risk and associated hazard due to wastewater irrigation and the consequence of heavy metals accumulation in the edible portion of experimented vegetables. The present study was carried out to assess the potential toxicity of acetone extract of A. tricolor with some essential parameters such as haematological and biochemical parameters, liver and kidney weight and their histopathological study. After conducting in vivo acute and subchronic toxicity experiments using the rat model, there was no toxicity or mortality observed between domestic sewage water and well water irrigated to red amaranth, A. tricolor.

Cotton (Gossypium spp.) is a profitable commercial crop that spans over 33 million hectares in 77 countries and is a vital source of natural fibre globally. It is extensively grown in India and supports over 60 million Indians, including 6 million farmers, the majority of whom are small and marginal farmers. The current study used a randomised block design with two replications and a spacing of 90 cm x 60 cm to explore 89 cultivars from one frequently planted tetraploid species (G. hirsutum) in an areolate mildew hotspot in Odisha during the kharif of 2019, 2020, and 2021. The infector row technique was utilised to supplement natural disease pressure, and the severity of grey mildew was graded on a 0-4 scale. Among all the genotypes tested GSHV-159 and GISV-272 were reported to be disease free. While 32 genotypes shown only moderate resistance to the disease, 22 entries had consistently strong resistance over three years. These genotypes can be used as Grey mildew resistant donors. Twenty-four of the types tested were vulnerable to grey mildew, while the remaining nine germplasms were extremely sensitive to the fungus. These findings support cotton producers, particularly small, marginal, and tenant farmers, in selecting the best genotypes with resistance to grey mildew disease, a hazard to the environment, the economy and most importantly, sustainable crop production.
棉花(Gossypium spp.)是一种盈利的商业作物，在77个国家种植超过3300万公顷，是全球天然纤维的重要来源。它在印度广泛种植，养活了6000多万印度人，其中包括600万农民，其中大多数是小农和边缘农民。本研究采用随机区组设计，2个重复，间隔为90 cm x 60 cm，在2019年、2020年和2021年三季对奥里萨邦areolate霉病热点地区常种四倍体(G. hirsutum)的89个栽培品种进行了研究。采用侵染者行技术补充自然病压，将灰霉病的严重程度分为0-4级。在所有检测的基因型中，GSHV-159和GISV-272报告无病。虽然32个基因型仅显示出对该疾病的中等抗性，但22个条目在三年内始终具有很强的抗性。这些基因型可用作抗灰霉病供体。其中24种对灰霉病易感，而其余9种种质对灰霉病极为敏感。这些发现支持棉花生产者，特别是小农户、边缘农户和佃农，选择抗灰霉病的最佳基因型，灰霉病是对环境、经济和最重要的是可持续作物生产的危害。

The infector row technique was utilised to supplement natural disease pressure, and the severity of grey mildew was graded on a 0-4 scale. Among all the genotypes tested GSHV-159 and GISV-272 were reported to be disease free. While 32 genotypes shown only moderate resistance to the disease, 22 entries had consistently strong resistance over three years. These genotypes can be used as Grey mildew resistant donors. Twenty-four of the types tested were vulnerable to grey mildew, while the remaining nine germplasms were extremely sensitive to the fungus. These findings support cotton producers, particularly small, marginal, and tenant farmers, in selecting the best genotypes with resistance to grey mildew disease, a hazard to the environment, the economy and most importantly, sustainable crop production.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87561400","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}

A synthesis of two forms of activated carbons is included in this paper. Because of its capacity to remove contaminants from both air and water, activated carbon (AC) is commonly employed for purification. Its porous structure allows it to trap impurities, and it is frequently suggested for a variety of water and wastewater treatment applications. However, due to the high expense of filing an AC application, the number of applications that can be filed is limited. AC was made using locally accessible Peltophorum pterocarpum (Copper Pod) and Phoenix dactylifera (Date Plam) seeds in this study. Fluoride adsorption on physical activated carbon from a synthetic sample made from Peltophorum pterocarpum (Copper Pod) and Phoenix dactylife. To remove fluorine from the body physically activated carbon, adsorption in batches methods were completed in order to find the best time, dose, pH sorption kinetics, and sorption equilibrium. The ideal contact duration, dosage of adsorbent and carbon pH were found to be 30 minutes, 140 mg, and 8.00, and 50 minutes, 225 mg, and 9.00, with fluoride removal efficiency of 77.5 percent, 79.33 percent, 82.6 percent, and 72.63 percent, 75.8%, 76.5 percent, respectively. Changes in process factors such as adsorption time and dosage were recycled to inspect adsorption kinetics and sorption isotherm models. The isotherms of Langmuir, Freundlich, and Temkin are three scientists investigated using This experimental data has been determined to be accurate.

Field experiment was conducted during 2017-18 at Sugarcane Research Institute, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar to study the effect of row spacing on yield and quality of early maturing sugarcane genotypes. Treatment included two row spacing (90 and 120 cm) and five genotypes viz., ‘CoLk 12207’, ‘CoP 12436’, ‘CoSe 12451’, ‘BO 130’ and ‘CoSe 95422’. Significantly higher plant population, leaf area index (4.18), dry matter accumulation (34.8 t/ ha) and millable canes (126, 200/ ha) were recorded with 90 cm row spacing gave significantly highest cane (96.2 t/ ha) and sugar yield (11.6 t/ ha). Results showed that genotype CoSe 95422 superseded other genotypes in growth and yield attributing characters. Maximum cane yield (104.4 t/ ha) was noticed due to the genotypes CoSe 95422. However, maximum brix (20.3%), pol (18.13%) and CCS percent (12.60%) were noted with the genotype CoLk 12207 which was statistically similar to BO 130. Significantly higher sugar yield (12.4 t/ha) was obtained with the genotype CoSe 95422 which was statistically comparable to CoLk 12207 and CoSe 12451.
