Continuous and ever-increasing use of imidacloprid for the control of sucking pests, chewing beetles and soil insects, leads to diverse tribulations in the environment. The metabolites formed after degradation may have greater insecticidal and mammalian toxicity. The degradation studies in soil are very imperative to study the evaluation of pesticides and its metabolic products in the environment. Due to very limited information regarding dissipation behavior and its metabolic degradation of imidacloprid in soil, the present study was undertaken to estimate the dissipation pattern of the parent compound imidacloprid and its metabolites in different types of soil. Different types of soil i.e. sandy loam, loamy sand and clay loam soil were collected from different geographical locations of Punjab. Each type of the soil samples were treated with different concentrations of imidacloprid i.e. 100, 200 and 400 mg/kg. The samples were maintained at 25 ± 2°C in laboratory. After 7 days of treatment with 100 mg/kg imidacloprid, the total residues of imidacloprid and its metabolites for sandy loam, loamy sand and clay loam soil was reported to be 65.39, 68.96 and 69.99 mg/kg, respectively. Sandy loam soil type showed greater dissipation behaviour of imidacloprid followed by loamy sand and clay loam soil. Even after treatment with high doses of imidacloprid, traces of metabolites residues such as 6-chloronicotinic acid, nitroguanidine, olefin, nitrosimine, urea and 5-hydroxy were detected.
Ordinary agricultural machinery is prone to tipping and tail swinging in hills and mountains, a wheeled robot whose attitude can be adjusted was designed in this paper. In order to carry out high precision and fast positioning, a three-point support leveling scheme was adopted, and a plane for positioning was used. The robot chassis is mainly composed of a front steering drive axle, two rear tire swinging mechanisms. The front steering drive axle can rotate around the longitudinal axis of the chassis, and the two rear wheels can swing around the hinge point, thus the attitude adjustment is realized. The design and calculation of the walking mechanism and the attitude adjustment mechanism were carried out, and the key parameters were obtained. An attitude intelligent detection and control system composed of vehicle-mounted industrial computer, STM32 controller, LIDAR and attitude sensor was also built. The attitude intelligent detection and control system was built based on the ROS, and the look-ahead control technology was used to plan the attitude adjustment path. The slope-climbing test of the prototype shows that the X-axis angular velocity is reduced by about 25% and the Y-axis acceleration is reduced by about 60%, which greatly reduces the possibility of tipping and rolling over. The turning test of the prototype shows that the acceleration along the X-axis can be reduced to zero, and the angular velocity around the Z-axis can be reduced by about 15%, which greatly reduces the risk of roll over and tail swing.
Khasi mandarin is among the most well known commercial fruits of the North-Eastern region of India. Its cultivation in Assam has been hindered due to an onslaught of insect pests and disease problems. The use of IPM modules is a promising strategy for the effective management of insect-pests in Khasi mandarin. Hence, a programme was undertaken for the development and dissemination of recommended IPM technologies among the Khasi mandarin growers of Tinsukia district of Assam under ICAR-NCIPM-TSP project during 2018-2021. The various IPM interventions were practically explained to the growers by organizing village level group discussions, trainings, front line demonstrations, farmers scientist interactions, farmers’ exposure visits and regular field visits. The importance, need and benefit of IPM strategies were described categorically. IPM technologies were disseminated to a total of 65 adopted beneficiaries. Forty five percent (45%) farmers of that locality adopted this new technology and management of the pest with this technology seems to be result oriented.
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.
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.
