Experimental Observations Rheological Behavior Aluminum Oxide and Multiwall Carbon Nanotube Dispersants in a Mixture of Water and Ethylene Glycol Hybrid Nanofluid

Paper ID- AMA-07-08-2021-10572

Micro and nano colloidal suspensions in conventional fluids are identified as potential fluids for heat transfer cooling applications. The pumping power of any fluid mainly depends upon the viscosity of the working fluid. In this present work, the viscosity of the nanofluid is compared with conventional fluids. The hybrid nanofluid viscosity and shear stress are measured by varying the shear rate from 0-500s-1. The nanoparticles are composite MWCNT and aluminium oxide (10:90) ratio percent by weight or (13:87) ratio percent by volume. The coolant mixture of (80:20) % volume water and ethylene glycol has good antifreeze properties. The rheological properties are measured for volume fractions 0.004-0.028% and various temperatures from 25oC- 55oC. The findings showed that the viscosity increased with the loading of nanoparticles along with the decrease in temperature. Hybrid nanofluid's viscosity rises to 9.9% of base fluid at 25oC for premier volume fraction 0.028%. Shear stresses the shear strain rate following the linear trend for all the volume fractions, obeying Newton's Viscosity law called Newtonian fluids.

Toxicity Characteristics of Acetamiprid Insecticides Against Adult Earthworms, Eisenia Fetida

Paper ID- AMA-07-08-2021-10571

The use of neonicotinoides insecticides, particularly acetamiprid, in agriculture is increasing day by day to increase crop yields, but their excessive use has reduced beneficial soil fauna and flora, which directly or indirectly affects soil health. Crop yield is inversely proportional to invertebrate flora, with earthworms being the most affected organisms by pesticides. During pest management programmes in agricultural fields, through direct application as well as foliar wash-offs or drift, large amounts of acetamiprid active ingredients are typically deposited on the soil. Studies on the impacts of neonicotinoids pesticides have primarily focused on acetamiprid's effects on earthworm’s morphological parameters as well as behaviour. Acetamiprid LC50 values derived using the Probit analytical method were 0.165g/cm2, which is the pesticide concentration that kills 50% of earthworms. As the concentration of acetamiprid rises, so do the negative effects on earthworms, with bulging of the anterior end, body constriction, preclitellar swelling, clitellum bulging, tapered end swollen, oozing out of coelomic fluid, loosened segments, formation of a knot-like structure at the anterior end, cuticle rupture, and desegmentation among the changes. Furthermore, earthworms demonstrated dark coloration, leaking out of hemocoel, perforated cuticle, and epidermal peeling at an acetamiprid dosage of 0.240g/cm2.

Weed dynamics, crop productivity and profitability of pearl millet as influenced by mechanized weed control under semi-arid agro-ecology of India

Paper ID- AMA-07-08-2021-10570

Identification of appropriate method of mechanical weed control and inter-culture suitable crop row spacing are the important researchable areas in pearl millet agronomy. Considering this research gap, field experiment entitled “Weed dynamics, crop productivity and profitability of pearl millet as influenced by mechanized weed control under semi-arid agro-ecology of India” was undertaken with the aim of finding out the effect of experimentation on weed dynamics (weed flora distribution, weed density, weed control efficiency and weed index), crop productivity and profitability parameters (gross returns, cost of cultivation, net returns and benefit: cost (B:C) of pearl millet. The field experiment was carried out in Kharif, 2017 at Regional Research Station, Bawal, Rewari of Chaudhary Charan Singh Haryana Agriculture University (CCSHAU), Hisar. A combination of twelve treatments (manual weeding by kasola and wheel hand hoe however; mechanized weeding by tractor and power weeder) were allocated in randomized block design and replicated thrice. Dominant weed flora in the study were Cyperus rotundus, Trianthema portulacastrum, Digera arvensis whose relative weed density was 42% & 46%, 26% & 22% and 17% & 15% at 20 days after sowing (DAS) and at maturity stage, respectively. Treatment T8 (sowing at 60 cm row spacing and two inter-culture with power weeder) has resulted in lowest weed density and weed dry matter at 20 DAS while, T1 (sowing at 45 cm row spacing and two interculture with kasola) has resulted in lowest weed density, weed dry matter (2.66 & 3.41 g/m2) and weed control efficiency (92.5 & 89.1%) at 40 DAS and at maturity respectively T1 also resulted in lowest weed index (3.09%), higher crop productivity (29.43, 68.50 and 97.93 q/ha of grain, stover and biological yield, respectively) and high value of cost of cultivation and gross returns. However, T7 (sowing at 60 cm row spacing and two interculture with tractor) noted with at par productivity but higher net returns (Rs/ha, 23777.7) and higher B: C ratio (1.80) than T1.

Current adoption status of inland fishery in Haryana state of India

Paper ID- AMA-07-08-2021-10569

Study was carried out in Haryana state to assess the adoption of inland fishery farming practices and constraints faced by fishery farmers of Haryana state. The findings revealed that majority of fish farmers (58.67%) possessed large size ponds and all were perennial in nature but 52.00 percent of them were using leased village ponds. The overall adoption for fish farming technology was low (56.00%). While the practices such as recommended species, watering of ponds and stocking fish seed, recommended fish seed rate or fingerlings application, proper harvesting period and pond site management practices were fully adopted by farmers whereas, least adopted practices included control of aquatic weeds, ploughing of pond, disease control measure and application of recommended manures and fertilizers. However, very serious constraints in fish farming were viz. lack of knowledge of field functionaries for post-harvest management practices, lack of knowledge of modern storage structures, non-availability of fish feed and seed at proper time in villages, lack of remunerative fish MSP policy, wide price fluctuations, high price of fish seed and no cold storages at villages. Both technological empowerment as well as remunerative and assured markets is very crucial for sustainability and profitability of this farming enterprise.

The Effect of Chicken Manure Fertilizer and Arbuscular Mycorrhizal on Growth and Yield of Pearl Grass (Hedyotis corymbosa)

Paper ID- AMA-07-08-2021-10568

Pearl grass is a plant that can be used as a medicine for various diseases, such as cancer, hepatitis, diabetes, wounds, eye pain, fever, and stomach. Pearl grass contains several chemical compounds, and of them are ursolic acid and oleanolic acid. Using chicken manure and arbuscular mycorrhizal has the potential to be a cultivation technology to determine ursolic acid levels in the pearl grass. The research was carried out in Jumantonso, Karanganyar, Central Java.  The research was conducted from December 2019-February 2020. The study used a completely randomized design (CRD) with 2 factors. The first factor is chicken manure at a dosage of 0, 7.5, 15 tons/ha. The second factor was arbuscular mycorrhizal at the dosage of 0, 5, 10, 15 g/plant. The treatment combination consisted   of 5   replications.   The   variables observed were plant height, number of branches, plant crown diameter, root length, plant root weight, fresh plant weight, plant dry weight, and ursolic acid content. The results showed that the application of chicken manure 7.5 tons/ha was able to affect all parameters except for the length and weight of pearl grassroots. The various doses of arbuscular mycorrhizal did not affect all growth and yield parameters of pearl grass. Application of chicken manure and arbuscular mycorrhizae resulted in high levels of ursolic acid in most treatment doses. The application of chicken manure and arbuscular mycorrhizae increased the growth and yield of pearl grass but did not provide interaction on the growth and yield of pearl grass.
