Results showed that application of herbicides observed highest net returns, B: C ratio and nutrient uptake. Among herbicides, atrazine 500 g a.i. ha-1 (PE) fbtopramezone 25.2 g a.i.ha-1 at 20-25 DAS fetched significantly highest net returns of `54984 ha-1 being at par with atrazine 500 g a.i. ha-1 (PE) fbtembotrione 120.75 g a.i. ha-1 at 20-25 DAS (`52500 ha-1), over rest of the treatments under investigation. Furthermore, maximum and significantly higher Benefit: cost ratio was obtained in treatment receiving atrazine 500 g a.i. ha-1 (PE) fbtopramezone 25.2 g a.i. ha-1 at 20-25 DAS (3.42).A weedy crop resulted least nutrient uptake than weed free crop.The highest nutrient uptake (kg ha-1) was recorded under treatment receiving two hand weeding at 20 and 40 DAS followed by atrazine 500 g a.i. ha-1 (PE) fbtopramezone 25.2 g a.i. ha-1 at 20-25 DAS.

The experiment was laid out in RCBD with three replications at spacing of 45×45 cm2. By estimating D2 values in all possible combinations of the genotypes, the 21 genotypes of chilli were grouped into 6 clusters based on green fruit characters, revealing the genetic diversity among the parents. Cluster IV had maximum (6) andCluster I with only one genotype. Average intra-cluster distance was maximum in cluster VI (19.56). The inter cluster distance was recorded maximum between cluster I and VI (207.49).

The present study aimed to estimate the mutagenic sensitivity of black gram accession- IC-436524 with Ethyl methane sulfonate. Accordingly, this study checked whether the mutagenic activity has been inherited to the next generation M2. Data analysis has been performed for the determination of significance in germination percentage, seedling length (cm), seedling vigor index, root length (cm) and seed survival rate (Day 1 to Day 15) that were observed to be highly significant (p<0.01) for above characters except root length (cm) for treatments. It clearly indicated that there was adequate amount of variability among the black gram mutant due to treatments. The collected data for 7th day observed that seed germination percentage was higher at 0.2% and 0.3% EMS treated mutants and lowest germination percentage was observed in 0.5% EMS treated mutants. Seedling length (cm) was recorded highest in 0.2% EMS treated mutants and lowest seedling length (cm) was recorded in control. Maximum seedling vigor index was recorded in 0.2% EMS treated mutants and lowest seedling vigor index was showed for 0.5% EMS treated mutants.

The study was conducted at the College of Forestry, Ponnampet, Karnataka in 2020. The wood core samples were collected from the trees falling under 130 to 150 cm girth class, standing in coffee-based agroforestry systems of Kodagu, Karnataka, India. A total of 12 wood core samples were collected using the Presseler’s increment borer at breast height level. For wood fibre analysis the core portion was divided and three, i.e., near to the pith portion, middle and periphery, and made as a composite sample. Core samples were macerated using Jeffreys solution technique at Forest Product and Utilization Laboratory, College of Forestry, UAHS, Shivamogga. Fifty measurements on fibre parameters (Fibre length, Fibre width, Fibre wall thickness, and Fibre Lumen width) were recorded for each sample under a stereomicroscope with an inbuilt Image Analyzer. The mean fibre properties recorded, were used for calculating wood anatomical indices such as the Runkel ratio, Slenderness ratio, Flexibility coefficient, and Rigidity coefficient using standard formulas. The mean Runkel ratio, Slenderness ratio, Flexibility coefficient, and Rigidity coefficient were 0.580, 60.132, 63.290, and 0.184 respectively. The anatomical screening suggests that the species can be used as raw material for paper production, based on the indices.

On this subject, we perform a global literature review. Organic farming employs integrated production practises that reduce the environmental impact of inorganic fertilisers, herbicides, and genetically modified organisms. In terms of environmental and climate change effects, organic farming is less polluting than conventional farming when measured per unit of land. Organic cuisine is gaining popularity around the world. The main driver of increased demand is consumer concern about the detrimental impacts of conventional agriculture on the environment and human health. All across the world, various organic agricultural practises are practised. They are united by common aims of economic, environmental, and social sustainability. Many countries currently have specific legislative underpinnings for organic farming, as well as production and processing certification programmes. The expansion of organic agriculture practises and markets demonstrates how this is a viable alternative to intensification. More political will and scientific money could help realise more of this potential. In addition to developing organic agriculture, this should inform and improve the sustainability of other forms of agriculture.","PeriodicalId":13829,"journal":{"name":"International Journal of Economic Plants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82698409","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}
