Research on a method to measure and calculate tillage resistance of tractor mounted plough

Paper ID- AMA-05-08-2021-10499

In the conventional electro-hydraulic hitch control system, the method of measuring the tillage resistance could not accurately reflect the tillage resistance of the mounted plow. We analyzed the method of measuring the tillage resistance and proposed a method of measuring the tillage resistance of the mounted plow by the action signal of the hinge points of the upper link and the lower link. The tillage resistance analysis matrix was constructed using the spatial vector mechanics analysis principle. The resistance measurement system prototype was developed on the JINMA 1204 tractor. We analyzed the ill-conditions of the analysis matrix and developed a calculation program for tillage resistance. A field test of the tillage resistance measurement system was carried out, and the test result showed that the correlation coefficient between the measured value of the tillage resistance measurement system and the test value was 0.79, which showed a strong correlation. Resistance is effective. Through the calibration of the resistance measurement system, the maximum reference error between the tillage resistance measurement value and the tillage resistance test value is 5.7%, which meets the measurement requirements for electro-hydraulic hitch control of agricultural tractors.

Designing and testing an innovative soybean seed grader with oval-hole screen type

Paper ID- AMA-05-08-2021-10498

In order to improve the performance of the existing soybean seed sorter using the commonly used spherical hole screen type, an innovative sorter using the oval hole screen type was designed and tested. The design process was carried out at the Agricultural Mechanization Laboratory, while the performance testing process was carried out at the Muneng Laboratory of the Legume and Tuber Crops Institute (ILETRI) in Indonesia from January to December 2011. For comparison, a sorter designed using an elliptical hole screen type (hole size: 6,5,4 mm) and a spherical hole screen type (hole size: 6,5,4 mm) was used at both ends and the screen with a screen inclination of 10 °. Spring-supported at both the center. The sorter was driven by a 5.5hp gasoline engine and operated at a pulley speed of 432rpm. The performance of the sorter was evaluated by using large seed size varieties of soybean seeds (Grobogan and Argpmulyo) and medium seed size varieties (Wills). The results show that the sorter (ILETRI sorter) with an elliptical hole screen type (hole size: 6,5,4 mm) was used for both types of soybean seeds (large and medium size) compared to the spherical hole screen type. On the other hand, it was shown that the seed quality grade (Gi) can be increased. The capabilities of the ILETRI sorter were higher for all large seed size varieties: Grobogan (656 kg / hr) and Argpmulyo (678 kg / h) compared to medium seed size varieties: Wills (437 kg / h). Furthermore, by using this sorter, the seed grade can be divided into two grades (G1 and G2) with respect to Grobogan, and the ratio of G1 and G2 is 56.6% and 37.8%. The average diameters were 9 mm and 8 mm, respectively. On the other hand, for the other two varieties (Argomulyo and Wills), the seed grades were divided into three grades, namely G1, G2 and G3. On average, the percentage of G1 and seed diameter were 51.9% and 6.6 mm for Argomulyo and 14.6% and 5. for Wills. It was 1 mm. The G2 ratio and seed diameter for Argomulyo were 33.7% and 6.5 mm, while for Wills they were 23.8% and 6.0 mm. However, the ratio of G3 to Argomulyo and Wills was 14.4% and 56.15%, respectively, and the average seed diameters of both varieties were 6.4 mm and 4.8 mm, respectively. The indicators of seed homogeneity were similar for both types of seeds with a coarse: medium: fine ratio of 10: 0: 0, suggesting that the level of homogeneity reached 100%. However, on the other hand, the seed survival rate met the criteria for seed elongation (70%). On average, the seed viability of Grobogan, Argomulyo and Wills was 82.5%, 87.1% and 74.6%, respectively. With a price of Rp16 million / unit and a wage of two drivers with Rp150,000 per day, the cost of the ILETRI sorter is Rp52 / kg, the break-even point is 103t / year, and the rate of return is 6.0. In months, the net present value is Rp73.9 million, the profit-to-cost ratio is 1.67, and the internal rate of return is 199.8%. In conclusion, technically and economically, the ILETRI sorter has a beneficial prospect of being applied in soybean seed producers. The ILETRI soybean seed sorter is patented in Indonesia with patent number: S002012000 65. (Translation author abstract) Meet the criteria for seed elongation (70%).

Paper ID- AMA-05-08-2021-10497

This paper reports a new design of a deep fertilizer suitable for double row application in one ridge, as is commonly used on flat land in Guizhou Province, China for tobacco production. This fertilizer applicator can simultaneously achieve soil cultivation, ridge making and accurate fertilization. The implementation of the fertilizer applicator is combined with a system that controls fertilization based on operating speed. Conducted tests were conducted in a series of field experiments. As a result, tilling, ridged and fertilizer application can be carried out at the same time, the fertilizer application can be carried out deeply and accurately with a coefficient of variation of fertilizer uniformity of 12.3%, and 0.41 when the coefficient of variation of fertilizer application amount is 4.58%. The operating efficiency is hm 2 / h, and good ridges are formed with ridge height, apex width and foundation width of 28 mm, 1,318 mm and 1,755 mm, respectively, and the allowable range of the target values ​​of 30 mm, 1300 mm and 1700 mm. It was shown that it was.

Authentication and Validation of Cytoplasmic Wheat Hybrids with Linked SSR Markers

Paper ID- AMA-04-08-2021-10495

Wheat is the major cereal crop in India on which the food security rests. Determination of the best selection criteria is the most important aim in wheat breeding programs. To achieve high yield potential in wheat, hybrid breeding is a major innovative technique. A total of 16 newly developed CMS lines and a restorer lines, were used as the experimental material. Out of 82 pairs of SSR marker, Six SSR markers viz. Xcdf23, Xgmw374, Xgwm371, Xgwm335, Xwmc285 and Xwmc617, were analyzed for confirming that, the male sterility is controlled by a single dominant Ms2 gene in sixteen male sterile parental lines. Sixteen maintainer parental line were amplified with four SSR markers Xwmc131, Xwmc503, Xwmc44 and Xcdf63 to exhibit the Rf3 fertility restoration gene. Rf3 gene controls fertility in maintainer and hybrid lines and was found to be linked with the four SSR markers. The parental polymorphism survey indicated that four SSR markers viz., Xwmc346, Xbarc61, Xgwm294-2A, and Xgwm46-7B gave clear cut differentiation in both the (male and female) parents and indicated polymorphism among them, which confirm the authentication of hybrids.

Multi User Detection For FD-MC-CDMA system In Presence Of CFO Using Fuzzy Logic Based Adaptive Genetic Algorithm

Paper ID- AMA-04-08-2021-10494

Novel Multi User Detection (MUD) techniques to improve the efficiency of receiver in 5G wireless communications with the Frequency Division Multicarrier CDMA (FD-MC- CDMA) receiver are suggested in this research paper. Carrier frequency offset (CFO) on Multi-Carrier systems minimizes the efficiency of system; therefore, it is essential to estimate of CFO and minimize the influence on multiple carrier modulations systems. Introduction of novel MUD Schemes, Carrier Frequency Offset Estimation techniques on FD-MC-CDMA system are also focussed. There are several existing Multiuser Detection (MUD) schemes that suffer from performance degradation issues like optimisation in MAI and noise in the system, Near-far effect and Inter Symbol Interference (ISI). The combination of FD- MC-CDMA and MUD system is introduced and is designed for a novel Adaptive Genetic Algorithm (AGA) aided MUD using the Soft Computing Approaches such as Adaptive Population Sizing in Genetic Approach and Fuzzy Logic Controllers into the Adaptive Genetic Algorithm are simulated and analysed. The Bit Error Rate (BER) and Evaluation Complexity of the suggested MUD Schemes has been investigated under various Frequency Selective Fading Channels such as Additive white Gaussian noise (AWGN) channel, Rayleigh Fading Channel, and Rician Fading Channel. The simulation results are compared with existing non-linear MUD schemes, Successive Interference Canceller (SIC) and Parallel Interference Canceller (PIC). From the simulations, it is indicative that the efficiency of suggested AGA aided MUD is superior when compared to mentioned approaches.
