EFFECT OF INVERTED T-TYPE FURROW OPENERS OF NO-TILL MACHINE ON SOWING UNIFORMATY

Paper ID- AMA-22-08-2021-10636

This study was carried out to determine the suitability of the inverted T-type furrow opener of no-till machine used in many areas of the world but has not yet found production and use in our country. For this purpose, inverted T type furrow openers in different sizes and dimensions were designed and produced. Field trials were also made to determine the success of planting of T type furrow opener. Three different inverted T-type furrow openers (115°, 120° and 125° wing angles) and a conventional double disc furrow opener were tested in terms of plant emergence and distribution uniformity in field conditions. In the study; corn was sown by no-tillage planter with four different furrow openers under two different stubble conditions, namely the stand stubble and chopping stubble between 2018-2019 years. In this study, the inverted T type furrow openers were more successful than the double disc opener in terms of both plant emergence parameters and plant distribution uniformity. When the inverted T type openers are compared within themselves, the furrow opener with 125 ° wing angle (5,03 day) was successful in terms of plant emergence parameters and also the furrow opener with 120° wing angle (quality of feed index %87,87) was more successful in terms of accuracy of horizontal plant distribution.

An analysis of a vibratory soil compactors ride comfort with two types of hydraulic cab mount systems

Paper ID- AMA-21-08-2021-10635

The purpose of the present study to analyze the performance of two different types of hydraulic cab mount systems (HCMs) of a double drum vibratory soil compactor (DVSC) in the direction of improving vehicle ride comfort. Firstly, a drum-vehicle-ground dynamic interaction model of DVSC under the different operating conditions is set up to analyze the ride performance of two different types of HCMs. And then, the mathematical model with the damping characteristic of two different types of HCM with the annular orifice (Type 1) and with the orifice and the annular orifice (Type 2) are set up to determine their nonlinear forces in the vertical direction with are connected with a mathematical model of the whole vehicle. Finally, the performance of two different types of HCMs analyzed and evaluated under the different operating conditions through the objective functions such the time domain and power spectral density (PSD) acceleration responses of the driver’s seat and pitching cab angle. The time domain and PSD acceleration responses of the vertical driver’s seat (as) and cab’s pitch angle (acphi) are chosen as objective functions The obtained results indicate that the peak amplitude values of as and acphi with Type 2 respectively reduce in comparison with Type 1 under the survey conditions that lead to significantly improved the ride comfort of DVSC with cushioning systems with high damping coefficient values. The study results propose a theoretical basis for the optimal design of the cab mount system for earth-moving machinery.

Economic Analysis of Cucumber-Based Crop Rotations Under Protected Structures in Haryana, India

Paper ID- AMA-21-08-2021-10634

The present study was conducted in Haryana state to find out the economics of crop rotation in the protected structures. In the study area, four cucumber-based crop rotations were found i.e. cucumber + cucumber (R1), cucumber + capsicum (R2), cucumber + tomato (R3), cucumber + lilium (R4). Sonepat, Karnal, and Hisar districts were purposively selected because of the predominance of protected structures. The results obtained in this study indicated that the R4 cropping rotation (₹4838447) has higher cost of cultivation followed by R2 (₹1765041), R3 (₹1760968) and R1 (₹1574530). Gross returns were higher in case of R4 cropping rotation (₹6942780) is a higher cost of cultivation followed by R3 (₹2261224), R2 (₹2215500) and R1 (₹2126250). Net returns were highest in R4 (₹2137185) followed by R1 (₹511720), R3 (₹500255) and R2 rotations (₹450459). The present study also revealed that maximum respondents were adopting R1 crop rotation because of the lesser cost of cultivation and higher net returns.

Screening of Various Genotypes of Okra [Abelmoschus esculentus (L.) Moench] Against Major Insect Pests

Paper ID- AMA-19-08-2021-10633

Out of 10 varieties of okra, Abelmoschus esculentus (L.) Moench screened against the sucking insect pests [leaf hopper, Amrasca biguttula biguttula (Ishida) whitefly, Bemisia tabaci (Genn.)] and fruit and shoot borer (Erias spp), none of the variety was found completely free from their infestation, although they differed significantly in their degree of damage and pest number to harbor. During both the kharif seasons, 2019 and 2020, Punjab Padmini reported as the least susceptible variety against both leafhopper (6.26 nymphs/plant) and whitefly (9.32 adults/plant) whereas, lowest fruit and shoot borer infestation was observed on Hisar Naveen (Percent shoot damage- 8.51 Percent fruit damage on number basis- 29.07 Percent fruit damage on weight basis- 29.93). Meanwhile, Arka Nikhita F1 was noted as the most susceptible variety among all the screened varieties against all three major insect pests (Leafhopper- 9.80 nymphs/plant; Whitefly- 15.29 adults/plant; Percent shoot damage by Earias spp.- 12.14 Percent fruit damage by Earias spp. on number basis- 37.18 Percent fruit damage by Earias spp.on weight basis-38.02) investigated during the study period. However, rest of the varieties viz., Hisar Unnat, Varsha Uphar, Punjab Suhawani, Arka Anamika, Punjab-8, Pusa Sawani, Parbhani Kranti were concluded as moderately susceptible varieties.

Closing Yield Gaps Through Agronomical And Socio-Economical Factors

Paper ID- AMA-18-08-2021-10632

Yield gap analysis of individual crops in a cropping system has been done to explore the opportunities for increasing crop production which may provide important information to the policy makers for augmenting food security. In this context, study has been undertaken in Terai Zone of India, specifically West Bengal. The cropping system predominantly in the area is Kharif Paddy-Potato-Jute. We used econometric models Multiple Regression Analysis, for identified the factor which is cause to yield gaps. The result shows that Yield gaps have been found for all crops as well as cropping pattern of farmers in various levels. Regression analysis reveals that various factors like participate family member in farming, family head of education, age of head, farm holding, contact with social office, manures, farm distance etc. remain the most significant ( p< 0.01; p<0.05; p<0.1 ) to influence the yield gap. This led to the conclusion that the yield gap could be deeply reduced by controlling local agronomic management and improving socioeconomic factors.
