Design and optimization of rotary cone feed pushing robot with a pose-adjustment mechanism

Paper ID- AMA-28-07-2022-11565

In order to meet the rapid growth of cattle and sheep breeding in China, a rotary cone feed pushing robot with a pose-adjustment mechanism was designed to replace manual work to reduce labor costs in this paper. The theoretical model of walking and rotary cone pushing was established, and the walking and pushing mechanism was designed and calculated, and the key parameters, such as the driving torque and power of walking, the rotary driving torque and speed of the rotary cone were obtained. In order to solve the problem that the existing pushing robot cannot push clean feed and walk on the slope, a cone attitude adjustment mechanism driven by an electric linear actuator was designed. The cone attitude adjustment mechanism is mainly composed of ternary link, a front end cam and a rear end cam. In order to reduce the driving force and shock, four kinds of convex contours are established by selecting the motion law of sinusoidal acceleration, improved sinusoidal acceleration, 3-4-5 polynomial and improved trapezoidal acceleration. MATLAB was used to write a program to check and calculate the minimum radius of curvature, and to establish a reasonable push and return motion angle. Using Solidworks Motion, the motion simulation analysis of the pose-adjustment mechanism using four kinds of cam profiles was carried out respectively. The analysis shows that the pose-adjustment mechanism designed by the motion law of sine acceleration is the optimal design, and its driving force, roller speed, acceleration and impact force are the smallest. The maximum driving force of the electric linear actuator is 1172N, the maximum speed of the roller is 19mm/s, the maximum acceleration is 3.6mm/s2, and the maximum reaction force on the roller is 748.5N.

Influence of new generation PGRs on qualitative characters of mango (Mangifera indica L.) cv. Dashehari

Paper ID- AMA-27-07-2022-11564

The present investigation was conducted at Horticulture experiment Station, Baramunda, OUAT, Bhubaneswar during the year 2017-19 with an objective to improve the qualitative characters and improve the sugar content of mango Cv. Dashehari by using Brassinostroids and Triacontanol. The experiment was laid in Randomized Block Design (RBD) with three replication and 12 treatments comprising spraying of Brassinostroids @ 0.5 and 1.0 ppm, Triacontanol @ each 300, 500 and 700ppm, its combination and control. The observations on different characters of fruit Viz. Fruit weight (g), Firmness (Kg/cm2), Physiological loss in weight (%), Carotenoid content (mg per 100 g), Ascorbic Acid (mg/100g pulp), Dry matter content (mg per 100 g), TSS (°Brix), Acidity content (%), TSS: Acid ratio, Total Sugar (%), Reducing sugar (%), Non-reducing sugar (%) were recorded. Among the treatments, T10(1 ppm BRs + 300 ppm triacontanol) recorded maximum Fruit weight (182.99 g), Carotenoid content (11.46mg per 100 g), Dry matter content (21.91mg per 100 g), Ascorbic Acid (35.3mg/100g pulp), TSS (17.71ºbrix), TSS: Acid ratio (75.88), Total sugars (16.91%), Reducing sugar (5.07%) and Lowest titrable acidity (0.234%) but minimum non-reducing sugar (11.12%) found in the treatment 0.5 ppm brassinosteroid. High firmness (3.67Kg/cm2) observed in T8 (0.5 ppm brassinosteroid + 500ppm triacontanol) and lowest physiological loss in weight (21.41%) in T9 (0.5 ppm brassinosteroid + 700ppm triacontanol).

Growth, yield and quality of groundnut (Arachis hypogaea L.) as influenced by macro and micronutrients application in coastal sandy soils

Paper ID- AMA-26-07-2022-11558

A field experiment was conducted during rabi, 2021-22 at Agricultural College Farm, Bapatla to assess the response of macro and micronutrients on growth and yield of groundnut in coastal sandy soil. The experiment was laid out in RBD with seven treatments replicated thrice. The treatments are T1- Control, T2- 100% RDF, T3- 125% RDF, T4- 100% RDF + Soil application of ZnSO4 @ 50 kg ha-1 and Borax @ 10 kg ha-1, T5- 125% RDF + Soil application of ZnSO4 @ 50 kg ha-1 and Borax @ 10 kg ha-1, T6- 100% RDF + Foliar application of ZnSO4 @ 2 g L-1, FeSO4 @ 5 g L-1 and Borax @ 1.5 g L-1 at 45 and 65 DAS, T7- 125% RDF + Foliar application of ZnSO4 @ 2 g L-1, FeSO4 @ 5 g L-1 and Borax @ 1.5 g L-1 at 45 and 65 DAS. The results indicated that there was a significant influence on dry matter production, number of pods per plant and yield and quality parameters such as oil yield and protein content by the application of macro and micronutrients. The maximum dry matter accumulation, number of pods per plant, haulm, pod and kernel yield were obtained by the treatment T7 which received 125% RDF + Foliar application of ZnSO4 @ 2 g L-1, FeSO4 @ 5 g L-1 and Borax @ 1.5 g L-1 at 45 and 65 DAS. However, the growth parameters such as plant height, number of primary branches, number of compound leaves and yield attributes such as shelling percentage and 100- kernel weight and oil content were not significantly influenced by the macro and micronutrients application.

Impact of different planting geometry and phosphorus doses on growth and yield potential of summer moong (Vigna radiata L.)

Paper ID- AMA-26-07-2022-11557

The present investigation was conducted at Agronomy Research Farm at ANDUA&T, Kumarganj, Ayodhya (U.P.) during Zaid season of 2021 to asses the planting geometry with phosphorus levels on growth and yield of summer moong. The twelve treatments were tested in Factorial Randomized Block Design with three replications keeping three planting geometries viz.,30 cm x 10 cm, 30 cm x 15 cm, 30 cm x 20 cm and four phosphorus levels viz., 0, 20, 40 and 60 kg/ha. The soil of field was silty loam and the pH of soil was 8.3. The summer moong variety of NDM-1 was sown on 16-04-2021 with seed rate of 20 kg/ha. and the crop was harvested on 25-07-2021. Results revealed that the growth attributes viz., plant population, plant height, dry matter accumulation, branches per plant and leaf area index were significantly higher at 30 cm x 15 cm planting geometry over rest geometry, respectively in summer moong. The yield attributes as number of pods per plant, length of pods, number of grains per pod and number of grains per plant were significantly superior in summer moong crop at 30 cm x 15 cm planting geometry compared to 30 cm x 10 cm and 30 cm x 20 cm planting geometry, respectively. The planting geometry of 30 cm x 15 cm were proved significantly superior in terms of seed, straw and biological yield and harvest index when compared to the rest of treatments, respectively. The increment percentage in seed yield of 10.15% and 6.34% compared to 30 cm x 10 cm and 30 cm x 20 cm planting geometry, respectively. The plant height, dry matter accumulation, branches per plant and leaf area index were found significantly superior upto 40 kg/ha, phosphorus over rest planting geometries, respectively except number of branches per plant upto 60 kg P2O5 /ha. The number of pods/plant, length of pods, grains/pod and grains per plant were significantly increased upto 40 kg P2O5 /ha over rest used phosphorus doses, respectively. The highest seed yield, straw yield biological yield and harvest index were recorded significant upto 40 kg/ha phosphorus over 0, 20 and 60 kg/ha P2O5, respectively and increased phosphorus levels at 60 kg/ha at par in respect harvest index only. The increment evaluated in grain yield of summer moong (37.16% and 20.72%) over control and 20 kg/ha phosphorus, respectively. Therefore, the planting geometry of 30 cm x 15 cm with used 40 kg/ha phosphorus were better performance in terms of growth and yield attributes and yields of summer moong in present field experimentation.

Cultural variability in isolates of Pyricularia oryzae causing rice blast disease in Jammu region

Paper ID- AMA-24-07-2022-11554

Rice blast (Pyricularia oryzae) is the most destructive disease of rice in Jammu & Kashmir. The variability status of P. oryzae was not studied in Jammu region, although many studies had been done in the Kashmir region, therefore the present study is first study which aimed at determining the cultural variability in the rice blast isolates of the Jammu region. In this research, leaf blast samples were collected from the rice growing areas of five districts of Jammu division and variability among 30 isolates of Pyricularia oryzae was studied with respect to cultural traits. The colony colour of thirty isolates collected during the survey were off white to greyish black, with circular or irregular margins and flattened to raised growth pattern. On the basis of colony growth pattern, margin and colour, the isolates were categories into 6 groups (A, B, C, D, E and F). All thirty isolates exhibited excellent variability in respect of colony growth pattern, margins and colony colour.
