APPLE PRICE FORECASTING USING DIFFERENT TIME SERIES MODELS FOR SOLAN MARKET, HP, INDIA
Agriculture is the major occupation for the people of Himachal Pradesh. The apple is Himachal Pradesh's important fruit crop, accounting for almost 49% of the total area under fruit crops and 85% of total fruit production. Various price series models viz. HWMS, ARIMA, TDNN and Hybrid ARIMA-TDNN models were tried to price series of apple for Solan Market for study period from January 2008 to December 2020. Best model is selected based on lowest RMSE value. Key results show that Hybrid ARIMA-TDNN models were performs comparatively well over other models for forecasting of apple prices.
Performance Evaluation of Planting geometry and Phosphorus levels on their Economics and Qualities of summer moong (Vigna radiata L.)
Field experiment were carried out during Zaid season of 2021 to find out the effect of planting geometry and phosphorus on economics and qualities in summer moong crop. An experiment was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). The experiment was laid out in Factorial Randomized Block design with three replications. The total treatment combinations were twelve and keeping three planting geometry viz., 30 cm x 10 cm, 30 cm x 15 cm and 30 cm x 20 cm and four phosphorus levels viz., 0, 20, 40 and 60 kg/ha. Results revealed that there was significant variation among different treatments in respect of economics, the planting geometry of 30 cm x 15 cm were proved significantly superior in terms of seed yield, as well as gross return, net return, and B:C ratio compared to other rest treatments of summer moong crop. Quality aspect as only protein yield was significantly increased at 30 cm × 20 cm planting geometry over rest of planting geometry. The percentage increment of its geometry over narrow planting geometry (30 cm × 10 cm and 30 cm × 15 cm) were 4.66 and 1.77%, in respect of protein yield, respectively. The highest grain yield of summer moong, economics viz., gross income, net income and benefit cost ratio were significantly more received upto 40 kg ha. P2O5 over 0 and 20 kg/ha. phosphorus levels, respectively. The percentage increment of 40 kg P2O5/ha. over no phosphorus and 20 kg P2O5/ha. were 37.16 & 20.72%, 35.05 & 19.86%, 49.76 & 27.55% and 38.71 & 23.45% in respect of grain yield, gross income, net return and B:C ratio, respectively. The protein content in grain and straw significantly improved upto 40 kg/ha phosphorus per ha. in summer moong. The significant response was observed upto 60 kg/ha. phosphorus application in protein yield only. The application of 40 kg P2O5/ha. enhanced the protein content in grain, protein content in straw and protein yield by a margin of 14.50, 4.80 and 12.09% over no phosphorus, respectively.
OPTIMIZATION OF GERMINATED BLACK KAVUNI BY RESPONSE SURFACE METHODOLOGY (RSM)
In many nations, rice is the main dietary source. 95 percent of the world's rice demands are met by Asia. Because of its unique sensory qualities, high nutritional content, and, primarily, because of its advantageous health features, black rice has attracted growing amounts of attention. Germination has been found to be a low-cost and efficient process for enhancing grain quality. Response surface Methodology (RSM) two factor and three level Central Composite Design (CCD) was employed to optimize the germination conditions of black kavuni. Based on the optimization, the optimized soaking and germination condition was 16 hours soaking and 48 hours of germination. The effect of response variable was overall acceptability (8.98), cooking time (24.47) and anti-oxidant activity (80.25). The texture and the quality attributes of brown rice can be enhanced through germination and it will be the future food for the upcoming generations due to it improve quality characteristics.
Design and optimization of rotary cone feed pushing robot with a pose-adjustment mechanism
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
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).
