In this context, a field experiment was conducted with green gram (cv: NVL-516) in anacidic soil of the Agricultural Research Farm, Siksha ‘O’ Anusandhan, Bhubaneswar with the objective to study the impact of combined soil and foliar application of nutrients on yield and protein content of summer green gram in Odisha. The experiment was laid out in a Randomized Block Design with three replications and eight treatments consisting of recommended dose of Nitrogen, Phosphorous, Potassium and Sulphur (NPKS) along with foliar application of 2% urea, diammonium phosphate (DAP), KCl, N: P: K (19:19:19) and 1%KNO3 and control.Foliar application was done two times at 30 and 45 DAS. The highest yield (1582 kg ha-1 ) was recorded in treatment where 1%KNO3 was applied as foliar spray along with the recommended dose of NPKS and was at par with 2%DAP(1574 kg ha-1). The protein content of seeds was found highest in treatment with foliar application of urea (22.6%) followed by KNO3 (22.4%), N: P: K (19:19:19) (22.4%) and DAP(22.1%).

The experiment was conducted at Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar in randomized block design with three replications. The results revealed that first four component axes had eigen values 1.0, representing a cumulative variability of 76.86 %. Principal component analysis (PCA) indicate that four components (PC1 to PC4) accounted for about 76.86% of the total variation present among all the traits. Out of total principal components PC1, PC2, PC3 and PC4 with values 33.781%, 19.02%, 13.859% and 10.206% respectively, contributed more to the total variation. The first principal component had high positive loading for 15 traits out of 17. Similarly, second and third principal component had 7 traits each, fourth component with 6 traits had high positive loadings which contributed more to the diversity. Genotypes in cluster V showed higher mean performance for most of the yield attributing traits. Therefore, selection of parents for different traits would be effective from this cluster. Thus, result of the present study could be exploited in planning and execution of future breeding programme in rice under direct seeded condition.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84512757","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}

In the present study, a yellow coloured bacterial colony was isolated which showed tolerance to high pH, and metals like lead, chromium and arsenic. Genomic DNA extraction followed by partial 16S rDNA amplification and sequencing study revealed the isolate to be Glutamicibacter sp. The bacterial strain showed luxuriant growth in pH ranging from pH5 to pH 11, and salt concentration up to 8% NaCl. The pigment was isolated by methanol extraction and identified to be beta-carotene through FTIR spectroscopy. The pigment showed absorption peaks at 436 nm and 466 nm. The pigment could not show antibacterial activity significantly. The pigments showed a good free radical scavenging activity which increased significantly under stress conditions. No such studies were done from the red mud ponds of Utkal Alumina earlier. Tolerance of the bacterial strain to various heavy metals indicates presence of heavy metals in the red mud. Identification of molecular mechanisms underlying the heavy metal resistance and use of the pigments as cosmetics can be carried out in future.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76913313","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}

Henna (Lawsonia inermis L.), is a plantation crop native to tropical and subtropical regions of Africa, Asia, and Australia and is found in arid and semi-arid zones. From its leaves a red orange dye agent is extracted which has an affinity for bonding with proteins, and thus is used to dye human body parts (skin, hair, fingernails), as well as leather, silk and wool. The present study was conducted purposively selected Pali district in arid zone of Rajasthan State of India. One hundred and twenty beneficiaries were selected purposively who have obtained training on improved henna production technologies and 120 non-beneficiaries were selected randomly in same number from same villages of study area. Thus, a total of 240 farmers was selected from 20 villages for the present investigation. it was found that more than half (57.91%) of respondents belong to medium level of adoption category followed by 27.08 percent of respondents belong to high level of adoption category.

In the current study, we studied we studied diversity and foraging behavior of floral visitors to floral visitors along with their visitation rate, frequency during 2019 and 2020. The data were collected at 0800–1000 hours (early morning foraging activity), 1000-1200 hours (late morning foraging activity), 1200-1400 hours (Noon foraging activity) and 1400-1600 hours (afternoon foraging activity). The results revealed that seven species of bees, five flies and three wasp species on the flowers of cauliflower. Apis mellifera, Apis dorsata and Apis florea were the dominant pollinator species with 162-214, 126-164, and 82-136 individuals, respectively in both years. The maximum foraging activity of the dominant pollinators was observed at 14:00 hrs followed by 12:00 hrs whereas the minimum foraging activity was recorded in the early morning hours 08:00. Floral visitors differed significantly in term of visitation frequency with A. mellifera as the most frequent visitor (14.00–15.37 visits/flower/5 min) followed by A. dorsata (7.50–8.90 visits/flower/5 min) and A. florea (9.80–10.63 visits/ flower/5 min) in both years. Similarly, A. mellifera had statistically highest visitation rate (26.93–27.40 flowers visited/min) followed by A. dorsata (12.62–15.13 flowers visited/min) and A. florea (15.93-16.00 flowers visited/min). The results suggested A. mellifera, A. dorsata and A. florea could be effective pollinators of cauliflower. Therefore, these three species can be effectively used on a commercial scale to increase crop yield.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85819538","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}
