In the agricultural field, continuously monitoring and protecting is an important task for the farmers because it enhances the crop growth. Continuous crop growth and output monitoring is an important feature of agricultural management during the developmental stage. This automated irrigation technique increases the agricultural productivity. In traditional farming method fertilizer for the crops is manually supplied. But, in the modern agriculture technique automating the irrigation system has become essential. There are various irrigation techniques available for the agricultural field. Among these irrigation techniques the most commonly used type of irrigation is the Drip irrigation Method. Nowadays, most of the farmers prefer to use drip irrigation because the quantity of water consumed through drip irrigation is quite low compared with the other irrigation techniques. To move ahead with the drip irrigation technique the process involved in drip irrigation is to be automated fully which does not involves any human intervention. The essential fertilizer to the crops will be supplied with the help of venturi pipes which is known as dripper lines. This method will decrease the man power for supplying fertilizers. Compared to the traditional irrigation system drip irrigation will consume less water. Drip irrigation can also provide water to the plant's roots. Using drip irrigation method the crop will be able to absorb more nutrients compared with the traditional irrigation methods. By automating the drip irrigation system the water consumption for the agricultural field can be further reduced. Various sensors, such as temperature sensors, rain sensors, pH sensors, and humidity sensors, can be used to accomplish this.

“…Kim and Park (2019) concluded that when the throat diameter was equal to the injection pipe diameter, the Venturi injector had its highest fertilizer injection efficiency. Chandramohan et al (2019) found that a 45° entry/exit angle coupled with a 33 mm inlet diameter Venturi injector yielded the maximum fertilizer injection flow at the lowest pressure difference. Li et al (2019) designed a Venturi injector with a thread, which had better fertilizer injection performance than existing Venturi injectors.…”

To improve the fertilizer injection performance of a non‐axisymmetric Venturi injector (NAVI), the effects of the contraction angle, diffusion angle, throat diameter and tilt angle of the injection pipe on the fertilizer injection performance of NAVI were examined. Based on the test, the original NAVI was optimized, and the fertilizer injection performance of NAVI before (F1) and after (F2) optimization was compared. Then, a non‐axisymmetric Venturi injector with arc diffusion (F3) was proposed. The results showed that when the water inlet diameter of the non‐axisymmetric Venturi injector was 25 mm, the optimal structural parameters were as follows: the contraction angle was 40°, the diffusion angle 6°, the throat diameter 7 mm and the tilt angle of the injection pipe was 120°. Compared with F1, the injection rate and fertilizer injection efficiency of F2 increased by 21–66 and 27–79%, respectively. Changing the diffusion section of NAVI into an arc structure was conducive to reducing the vortex area size by 11% and improving the injection rate by 20–62%. The results can provide an important reference for the structural design of Venturi injectors.

“…A irrigação por gotejamento tem sido amplamente difundida em todo mundo, principalmente, em regiões áridas e semiáridas, fato atribuído a seus bons benefícios com relação à economia de água (YANG et al, 2020). De acordo com Chandramohan et al (2019) é de fundamental importância o estudo de uma tecnologia eficiente de irrigação por gotejamento associado a conservação de energia para essas regiões em que há pouca disponibilidade de água, assim, a irrigação por gotejamento tem desempenhado um papel importante com relação a recursos hídricos e a otimização da eficiência do uso de água nessas regiões (KANG et al, 2017).…”

O conhecimento das dimensões do bulbo molhado do solo na irrigação por gotejamento superficial é um aspecto importante que vem chamando a atenção de pesquisadores pelo fato de definir tanto a lâmina e a frequência de irrigação, como também o número de gotejadores e o dimensionamento do sistema. Para isso, diversos modelos foram utilizados em diferentes trabalhos, destacando o modelo potencial e o de superfície de resposta para estimar as dimensões do bulbo em condições experimentais em função da vazão do gotejador e/ou tempo de aplicação de água. Nesse sentido, objetivou-se com este trabalho propor, ajustar e avaliar modelos matemáticos para estimar diâmetro máximo (Dmax), profundidade máxima (Zmax) e diâmetro superficial (Ds) do bulbo molhado usando o volume de 1,0 L de água. Para isso foram instalados seis experimentos em diferentes solos e avaliadas as dimensões do bulbo em função do volume de água aplicado. Foram propostos três modelos, sendo os valores de Dmax, Zmax e Ds para a aplicação de 1,0 L de água. Concluiu-se que os modelos estimaram satisfatoriamente as dimensões avaliadas, com coeficiente de determinação (R2) entre os valores observados e estimados variando de 0,9615 a 0,9896, 0,9212 a 0,9835 e 0,8904 a 0,9704 para Dmax, Zmax e Ds, respectivamente.
