Principal component analysis for assessment of genetic diversity in rice under Humid South-Eastern plain of Rajasthan
The present investigation was carried out during Rabi 2019 at Agricultural Research Station, Ummedganj, Kota Rajasthan, India to determine level of variability among twenty five rice genotypes in randomised block design using principal component analysis. First three principal components exhibited more than one Eigen values and accounted for 83.91 percent of total variation. PC1 accounted 49.18 % of the total variability contributed by the traits like number of grains per panicle, 1000-grain weight, grain yield per plant and amylase content, whereas PC2 account 24.39 % of the total variation that was contributed by the traits viz. number of productive tillers per plant, days to 50 % flowering, number of grains per panicle, days to maturity and plant height. PC3 had the contribution from the characters like productive tillers per plant, 1000-grain weight and grain yield per plant. Thus, the results revealed vast genetic variation and the traits contributing for the variation in rice genotypes can be used for various breeding programmes for improvement in yield and quality. Cluster I consisted of 7 cultivars showed maximum mean grain yield. Maximum inter cluster distance was recorded between cluster VI and VII. Cluster I had the highest mean values for grain yield and number of productive tillers per plant. Cluster VI had the highest mean values for 1000-grain weight, 1000-grain weight and Panicle length that had significant positive correlation with grain yield. The cultivars from these clusters with desirable characters may be used as potential donor for future hybridization program to develop high yielders.
Relative weed composition, soil fertility and wheat productivity as influenced by fertilization and herbicidal weed management practices
Wheat is the one of the major cereal crop grown under subcontinent of India which faces deficit soil fertility and problem of weed infestation. Optimum fertilization and weed management plays an important role in yield enhancement of wheat in the arid region under loamy sand soil. In the present study, Chenopodium murale contributed the maximum population to total weeds followed by Chenopodium album before and after spray of herbicides. fertilization with 150-50 kg NP/ha showed significant increase in plant height and dry matter at 35 and 50 DAS stage over fertilization of 120-40 kg N-P/ha and 90-30 kg N-P/ha while remain at par with 120-40 kg N-P/ha fertilization in respect of plant height and dry matter at 75 DAS and harvest stage, grain yield straw yield and biological yield. Available nitrogen in soil after crop harvest significantly increase upto 120-40 kg N-P/ha, however available phosphorus increase up to 150-50 kg NP/ha. Among herbicidal weed management, clodinafop-propargyl 15% + metsulfuron-methyl 1% at 64 g/ha was found to be the most effective for better wheat growth (plant height and dry matter), higher yield (grain, straw and biological yield) and available soil nutrients (N and P) after harvest of crop.
Antibacterial and Qualitative Phytochemical Analysis of Ghamra (Tridax Procumbens Linn) and Apamarga (Achyranthes Aspera) Weeds Extract
The aim of the study was to assess the antibacterial activity and phytochemical properties of leaf extracts of two common weed plants Ghamra and Apamarga. Aqueous and methanolic extracts were prepared using maceration and soxhlet extraction method. The extraction solvent was selected on qualitative analysis of antibacterial activity. Antibacterial potency of leaf extracts was tested by agar well diffusion method at different concentrations (10, 15 and 20 mg/ml) against two common human pathogens gram positive bacteria Bacillus cereus and gram-negative bacteria Pseudomonas aeruginosa. The results revealed that aqueous extract of Ghamra and methanolic extract of Apamarga were more effective. It was also found that Ghamra and Apamarga leaf extracts showed maximum zone of inhibition at 20 mg/ml concentration i.e. 20 mm and 18 mm against Bacillus cereus and 17.8 mm and 16.5 mm against Pseudomonas aeruginosa.
The relationship between the establishment of full-scale mechanization demonstration counties and the development of provincial agriculture and economy
The establishment of a full-scale mechanization demonstration county is a pioneering work in China to promote agricultural mechanization. As a spatial organization innovation for the development of regional agricultural mechanization, the full-scale mechanized demonstration counties are becoming an important variable affecting the provincial regional agricultural and economic development. Based on the growth pole theory and the spatial interaction theory, this paper analyzes the internal mechanism of the interaction between the establishment ability of a full-scale mechanization demonstration county and the level of agricultural development and economic development in the province. Using factor analysis and multiple regression methods, and by constructing the influence rate formula of independent variables on the dependent variables, this paper also empirically analyzes the correlation mechanism. It is found that, ①the level of agricultural development and economic development in the province has a positive impact on the establishment ability of a full-scale mechanization demonstration county. ②The establishment ability of a full-scale mechanization demonstration county has a positive impact on the level of agricultural and economic development in the province. Based on the conclusions, the paper puts forward some suggestions on the establishment of a full-scale mechanization demonstration county.
Study on dry anaerobic digestion of organic household waste in villages and towns
The purpose of this paper is to study the problems existing in dry anaerobic digestion of organic household waste and to provide theoretical basis for follow-up research. A study on medium temperature dry anaerobic digestion of simulated organic household waste was carried out in Datun Street, Peixian County, Xuzhou, Jiangsu Province, the experimental period was 60 d. On the tenth day of digestion, the concentration of ammonia nitrogen reached 1183.30 mg·L-1, and the concentration of ammonia nitrogen was as high as 4923.12mg·L-1 finally. Due to the high nitrogen content and total solid content of digestion substrate, serious acidification and ammonia nitrogen inhibition occurred in the digestion system, resulting in low methane content which the maximum only 30%. The cumulative biogas production could reach 361.68 L·kgVS-1, while the cumulative methane production was only 44.73 L·kgVS-1. The results of high-throughput sequencing showed that the digeston process was single in the bacteria and archaea, which explained one of the reasons for the serious inhibition of ammonia nitrogen.
