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.
Mechanical cultivation of wheat crop under varied establishment practices influences the quality, productivity and profitability
Wheat crop plays a vital role in the cereal crops to ensure the food security of India. In the high-yielding wheat production systems of Northwest (NW) Indo-Gangetic Plains of India (IGP), intensive tillage operations and burning or removing crop residue have led to high production costs, decreased farm productivity and profitability. Therefore, a field experiment was conducted to evaluate the effect of mechanical cultivation (tillage and crop establishment) and different crop residues on the growth, yields and economics of wheat at CIMMYT- CSSRI Research platform Karnal, India. The scenarios were included; Sc1- conventional tillage (CT) wheat without residue (-R); Sc2- Zero tillage wheat (ZTW) with rice residue (+R); Sc3- ZTW with full rice residue (+R); Sc4- Wheat on permanent beds (PBs) with partial maize residue (+R); Sc5- Wheat on PBs with partial soybean residue (+R); Sc6- Wheat on PBs with partial pigeonpea residue (+R). Compared to farmer practice (Sc1), CA-based management practices (Sc2 to Sc6) significantly improved the crop productivity, profitability and quality parameters. Based on 2' years mean, yield and net returns of varied management scenarios were increased by 11.4, 10.7, 7.2, 2.6 and 1.1 % and 17.4, 16.1, 13.6, 8.9 and 7.2% under Sc2, Sc3, Sc4, Sc5 and Sc6, respectively compared to Sc1 (farmers’ practice). Overall, CA-based management practices (mean of Sc2-Sc6) increased the yield by ~7%, net return by 13%, sedimentation value by 7%, gluten content by 22%, falling number by 6% and 20% reduce cost of cultivation compared to Sc1. Results suggest that CA-based management practices can increase yield, profitability and quality from wheat production in NW India.
