“…The technology of modern drip irrigation developed in the 1960s marked a significant step in the history of irrigation science (Camp, 1998). Many recent studies have proved the advantages of drip irrigation over surface methods of irrigation in terms of water saving, improved economic returns and increased yields and water use efficiency (Tagar et al 2012;Biswas et al 2015;Mali et al 2017;Mali et al 2019;Birbal et al 2018).…”

An experiment was conducted to test the efficacy of irrigation methods and mulching in seed production of chickpea. Irrigation methods included drip with mulch (DM), drip without mulch (DNM) and check basin (CB) irrigation. Drip irrigation was scheduled at 1-day, 2-day and 7 days interval, while farmers’ practice of check basin irrigation at 7-day interval was considered as control. Plant parameters like height, horizontal spread, dry matter, root length and root spread, and number of pods were significantly influenced by irrigation levels and mulch. Seed yield of 17.7 and 16.8 q/ha was recorded for DM having 1-day and 2-day interval, respectively, which was about 82 and 73% higher over the control. The harvest index increased with increasing irrigation interval and was highest (57.4) under treatments with longer irrigation interval (DM7, DNM7 and CB7). Drip irrigation at 1-day and 2-day interval recorded the water productivities of 0.54 and 0.52 kg/m3, respectively as against 0.30 kg/m3 recorded in farmers practice. Polythene mulch with drip irrigation at 2-day irrigation interval is recommended for improving the yields and water productivity of chickpea cultivated under eastern plateau and hill region of India.

“…Root growth and its distribution not only affect the absorption of water and nutrients of root, but also directly affect the growth of fruit trees and the quality and yield of apples. At present, machine vision is mainly concentrated in the upper part of the study of plants, such as the measurement of sunflower flower size by image processing [3], the classification of potato quality by machine vision and three-dimensional image [4], the estimation of apple fruit size by 3D technology [5], etc. The physical measurement of root morphological parameters mainly relies on the root scanners currently available in the market.…”

“…It requires a fixed hardware scanner and software [7]. Which is not only used to research the relationship between roots and soils [8], plant roots and water-saving irrigation [9], plant nutrition and water absorption [10], but also research the effects of different soils on main and lateral roots. This study developed and tested an image processing system to measure the morphological parameters of apple seedling roots (surface area, average diameter, length, and volume) accurately.…”

“…With the development of machine vision technology and research in the field of plant science, it has been widely used in the identification of plant species, plant growth information detection, quality inspection and classification of agricultural products as well as visual navigation of farmland. For example, Sunoj et al proposed measuring the size of sunflowers by machine vision in 2018 [3], Qinghua et al put forward to classify potato quality by machine vision in 2018 [4], Gongal et al proposed estimating the size of apple fruit by 3D machine vision in 2018 [5], Benoit et al simulated image acquisition in machine vision for seedling elongation, root segmentation algorithm for image processing validation in 2014 [6]. The application of machine vision-assisted electronic image analysis systems increases the precision and efficiency of plant production and avoids the subjective effects of human observation.…”

BackgroundTraditional measurements of apple seedling roots often rely on manual measurements and existing root scanners on the market. Manual measurement requires a lot of labor and time, and subjective reasons may cause the uncertainty of data; root scanners have limited scanning size and expensive. In case of fruit roots, coverage and occlusion issues will occur, resulting in inaccurate results, but our research solved this problem.ResultsThe background plate was selected according to the color of the seedling roots; the image of the roots of the collected apple seedlings was preprocessed with Vision Development Module by combining image and Labview. The root surface area, average root diameter, root length and root volume of apple seedlings were measured by combining root characteristic parameters algorithm. In order to verify the effectiveness of the proposed method, a set of measurement system for root morphology of apple seedlings was designed, and the measurement result was compared with the Canadian root system WinRHIZO 2016 (Canada). With application of SPSS v22.0 analysis, the significance P > 0.01 indicated that the difference was not significant. The relative error of surface area was less than 0.5%. The relative error of the average diameter and length of the root system was less than 0.1%, and the relative error of the root volume was less than 0.2%.ConclusionsIt not only proved that the root surface area, average root diameter, root length and root volume of apple seedlings could be accurately measured by the method described herein, which was handy in operation, but also reduced the cost by 80–90% compared with the conventional scanner.

“…The use of appropriate and timely fertilizers will help increase the success of the final results. The selection pattern and efficiency of fertilizer use affect plant growth (Naik, Jha, Singh, & Bhatt, 2019). Fertilization aims to replace lost nutrients and increase the nutrient supply needed by plants to increase crop production and quality (Dewanto et al, 2013).…”

This study aims to analyze the influence of input to output in the production process of rice and maize farming in the central paddy and corn production areas of Padang Pariaman Regency. This study also calculates the minimum production costs and the profit received. The data used are primary data and secondary data. The data analysis technique used is Multiple Linear Regression Analysis with Cobb-Douglas production function analysis. The results showed that land, seeds, fertilizers, and labor had a positive effect on rice and corn farming production. The minimum cost of rice farming is lower than corn farming. Corn profit is higher than rice profit.
