Weed control is one of the most time-consuming tasks, and manual weeding is inefficient due to labor costs, time, and tedium. Chemical weed management technologies have helped to alleviate these negative aspects. However, the growth of herbicide-resistant weeds, their environmental impact, and the growing desire for chemical-free foods have encouraged researchers to investigate alternate weed management strategies. A prototype of a walking-type battery-operated boom sprayer cum weeder was developed. The attachment was made to suppress inter-row weed plants mechanically. A brushless dc motor powers the mechanical weeding attachment. One of the most challenging aspects of this project was appropriately designing the weeding attachment and the sprayer for spraying. Both attachments would be joined with a machine to do mechanical weeding and spraying without affecting the crops. In this paper, various researches on sprayers, weeders, and combined configurations of sprayers & weeders have been discussed along with their working principles.
Prediction of seed vigor based on hyperspectral peanut. The traditional method is time-consuming and laborious to detect seed vigor. At the same time, the accuracy of the detection result is not high, and it will cause damage to the seed itself. Therefore, in order to achieve rapid and non-destructive detection of peanut seed vigor, the test was performed with original health, artificial aging for 24h and Peanut seeds with different vigor gradients at 72 hours were used as the research samples. Hyperspectral images with a wavelength range of 387~1035nm were collected, and the image of the central part of the peanut seeds with a pixel size of 60×60 after correction was intercepted and the average reflectance value was calculated. After the collection was completed, the individual peanut seeds were numbered one by one, and then the roll paper germination method was used to induce germination to ensure that the peanut samples collected by the spectrum were consistent with each other. There was a one-to-one correspondence between the peanut seeds in the induction test of roll paper germination. After a combination of processing analysis, characteristic band processing, and model selection, a hyperspectral prediction system with the highest correlation to the viability of extracted peanut seeds was finally established. Experiments shown that the combination of hyperspectral imaging technology and the MF-LightGBM-RF model had the best performance, with a prediction accuracy of 92.59% and a fitting time of 1.77s, which simplifies the model and improves efficiency.
The current study was conducted in Haryana's districts of Ambala and Kurukshetra in 2020 and 2021, to assess farmers' awareness of Direct Seeded Rice (DSR) cultivation technology in eight villages in these districts in order to improve resource use efficiency and lower rice cultivation costs. Empirical data was obtained using a well-structured and pre-tested interview schedule and analysed using appropriate statistical procedures utilising the Statistical Package for Social Sciences 26th version (SPSS). According to the findings, two-thirds of the respondents (41.25%) had a poor degree of knowledge regarding DSR technology, followed by medium and high levels of expertise. Indeed, the government and non-governmental groups should arrange more awareness programmes to raise the level of understanding of DSR technology in order to sustain rice production in Haryana. Personal attributes like education, land holding, farm equipment availability, mass media exposure, extension contact, economic motivation, risk orientation, and innovativeness all showed a positive and significant link with their awareness level about DSR technology at the 0.05 level of probability.
Experiments were conducted in two locations under the acidic soil conditions of Nagaland. Growth, yield, yield attributes and quality of soybean were recorded, analysed and computed statistically during 2019, 2020 and pooled respectively. It was observed that the parameters such as plant height, no. of nodules plant-1, fresh weight of nodules, dry weight of nodules, seeds pod-1, pods plant-1, seed and stover yield, protein content and yield, oil content and yield and soil fertility after harvest were significantly increased @ 5 kg ha-1 ZnSO4 H2O + RDF during both the experimental years as well as in pooled respectively. The fatty acids composition in soybean such as palmitic, stearic, oleic, linoleic and linolenic acid were also found to be significantly increased @ 5 kg ha-1 ZnSO4 H2O + RDF among the various Zn sources applied. From the experiment conducted, it was observed that soybean responded well to application of Zinc sources in balanced doses.
An air-assisted sprayer sends liquid medicine to a canopy of orchard plants for protection. However, the inherent drift in this method lowers the pesticide utilization. To meet the gardening requirements of a short-anvil densely planted apple orchard, a profiling boom sprayer was designed, and the operation requirements and prototype operation parameters of plant protection were determined. The droplet depositions in the upper, middle, and lower layers of the targets and in the inner, middle and outer rings were analyzed in field experiments. The standard deviations of the droplet deposition coverage rates on free, slender, and high spindles at different heights were 4.43, 2.82, and 5.29, respectively, and those of the droplet deposition densities were 5.97, 4.98, and 6.15, respectively. All p-values exceeded 0.05, indicating that droplets from the outer ring were uniformly distributed at different canopy heights. The average droplet deposition density exceeded 150 grains·cm-2 in the outer and center rings of the three tree-shaped targets, and reached 100.60 grains·cm-2 in the inner ring. The droplet deposition coverage rates on the free, slender, and high spindles in the inner ring were 37.41%, 36.69%, and 35.47%, respectively, indicating that the droplet penetration ability of the profiling boom sprayer meets the requirements of plant protection. The developed profiling boom sprayer has improved the inherent serious drift problem of the air blower sprayer, and has provided inspiration for the research and development of orchard plant protection machinery.
