Profitability Analysis of Backyard Poultry Farming in Kheda district of Middle Gujarat, India: A comparative study of Triple Cross Chicken Vs. Indigenous Chicken

Paper ID- AMA-23-08-2022-11634

Backyard poultry is an age-old practice in India, particularly in rural areas, where households raise small groups of local chickens for family food and game. Though India's poultry industry has proliferated in the previous five decades, it has primarily been limited to the commercial poultry sector, which is concentrated in and around urban and semi-urban areas. This study is to determine the profitability of backyard poultry production of Triple Cross and indigenous fowl in the Middle Gujarat region. A well-structured questionnaire collected data from 15 Triple cross fowl farmers and 15 indigenous fowl farmers in Kapadwanj Taluka of Kheda District in Middle Gujarat. The data was analyzed using profitability analysis and the Garret Ranking technique. According to the survey, income from hen sales accounts for 9.50 percent for Triple Cross fowl and 12.01 percent for indigenous fowl. Triple Cross fowl net income was 8617.12, while indigenous fowl net income was 6308.33. Compared to BC ratios of indigenous chicken, the BC ratio of Triple Cross chicken was more significant (2.58). (2.20). Tiny chicks up to the age of eight weeks are killed by predators such as dogs and cats, according to the study. The beneficiaries' second major constraint was a lack of knowledge about the scientific rearing of chicken.

Construction of a scale to measuring the attitude of farmers towards Rice Cultivation

Paper ID- AMA-20-08-2022-11630

A scale for measuring the attitude of the farmers towards rice cultivation was developed using Likert’s method of summated rating. Initially, 60 statements were framed and edited as suggested by Edwards. The edited 44 statements were subjected to relevancy test. The relevant statements were subjected to the procedure as suggested by Likert. Finally, t-values of the individual items were calculated. Only those items having t-values more than 1.75 were included in the final scale. Thus the final attitude scale consisted of 24 statements of which 14 positive 10 negative statements. The scale was found to be highly reliable with the reliable coefficient of 0.82.

ESTIMATED SOLUTION FOR THE LC-FILTER CURRENT COMPONENTS IN INVERTERS

Paper ID- AMA-19-08-2022-11626

Inverters are used in power converters, such as variable speed drive systems, Dynamic Voltage Restorers (DVRs) or UPSs, etc. The LC filter is an essential component in inverters. It helps that the output voltage remains the desired fundamental element and eliminates the converter's high-order harmonic feature. This research proposes a method to estimate the current through the capacitor of an LC filter from which it can be accurately determined to control.

Development of suitable IDM module against late blight of potato caused by Phytophthora infestans under climate change

Paper ID- AMA-18-08-2022-11623

The IDM practices have ability to increase growth parameters, yield and soluble protein and total phenol content and on the other hand decreases disease severity of late blight of potato. The highest plant height was found in T9 (Soil application of FYM + Poultry manure + Tuber treatment with T. harzianum+ three foliar spray with Equation Pro) treated plant representing the value 6.15 and 34.05 cm during 2016-17 and 6.30 and 34.65 cm during 2017-18 at 15 and 45 days age of seedling. Similarly, total yield as 417.30 and 449.40 gm per plant was also obtained from T9 (Soil application of FYM + Poultry manure + Tuber treatment with T. harzianum + three foliar spray with Equation Pro) treated plant, against 218.78 gm and 211.68 gm in case of control in year 2016-17 and 2017-18 respectively. The minimum disease severity of late blight of potato as 1.65 and 5.28% during 2016-17 and 1.70% and 5.35% during 2017-18 were recorded in T9 (Soil application of FYM + Poultry manure + Tuber treatment with T. harzianum + three foliar spray with Equation Pro) treated plant as against 30.12% and 48.84% (2016-17) and 30.50 and 49.05 % in case control at 45 and 60 days, respectively. Biochemical analysis of treated plants was also observed due to adaptation of IDM practices that soluble protein content in potato leaves due to IDM approaches ranges from 16.55-23.75 mg/g of fresh leaves with maximum in T9 treated potato leaves, indicating 34.02, 35.32, 36.54 and 37.97 mg/g of fresh leaves at 2, 4, 6 and 8 days of pathogen inoculation during 2016-17. Similar trend of observation has also been found during 2017-18. Similarly, the total phenol content as compared to control at 2, 4, 6 and 8 days of pathogen inoculation was also found in T9 (Soil application of FYM + Poultry Manure + Tuber treatment with T. harzianum + three foliar spray with Equation Pro) treated potato leaves posses increased percent of total soluble phenol as 81.91 % over control at 8 days of pathogen inoculation. Similarly, during 2017-18, the maximum total phenol content was also found in T9 treated potato leaves which were 2.69 mg/g, 3.21 mg/g, 3.31 mg/g and 3.40 mg/g of fresh leaves at 2, 4, 6 and 8 days of pathogen inoculation.

Optimizing and Experimenting of Carrot Root-stem Pulling Separation

Paper ID- AMA-16-08-2022-11616

Carrots are prone to impact damage during the root-stem separation stage, and it is easy to cause fruit damage due to the impact between the pull rod and the carrot. To reduce the damage of carrots harvested by pulling, the finite element method was used to study the critical velocity of carrot damage after the improvement of the pull rod (a rubber cushioning material with a thickness of 2mm, and inner diameter of 16mm, giving a 20 mm outside diameter, and elastic modulus of 100 MPa was wrapped outside the pull rod). The critical rotational speed of the disc driving the pull rods was solved by kinematic analysis of the pulling separation mechanism and impact velocity analysis of carrots. According to the nonuniform motion characteristics of the pull rod, a noncircular gear transmission device was designed, and a root-stem separation experiment was carried out. Because rubber cushioning material affected the success rate of separation and active disc rotational speed affected the damage rate of separation, the experimental factors were pull rod surface with or without rubber cushioning material and active disc rotational speed. Through the separation experiment, it was found that when the rubber cushioning material was used in the pull rod, and the conveyor belt velocity was 1 m•s-1 and the input rotational speed of the disc driving the pull rods was 180 rpm, the separation success rate of carrot was 90% and the damage rate was 5%.
