This modern agriculture sector provides numerous advantages such as efficient location and space requirements, adequate climate control, water-saving and controlled nutrients usage. Hydroponic cultivation is an agricultural method where nutrients are efficiently provided as mineral nutrient solutions.
In particular, inspiration from the action research method applied to interdisciplinary technology development becomes a participatory approach characterized by rapid prototyping cycles which allow iterative technology specification and development together with people in their real world environment. in robotics, embodied AI, and playware), in this paper we suggest a cyclic research method based on a mix between participatory and experimental processes. Based on two decades research in developing engineering systems with a societal impact (e.g. These researchers are challenged by the traditional research method of experimental research with a waterfall model which demands clearly defined project definition and functional requirements, and impose a sequential processes leading to the final system evaluation, which may lead to solutions which work in the lab, but have little impact in the messy real world. Several sub-disciplines of engineering are driven by the researchers’ aim of providing positive change to the society through their engineering. Based on these promising results, hydroponics, therefore, can be recommended as an alternative to soil based cultivation techniques and may be explored further for sustainable crop production and global food safety. Hydroponically grown plants showed a more luxuriant and faster growth rate, earlier initiation of flowering and fruiting and three to four times higher yield than the soil grown plants. The soil grown and hydroponically grown plants showed distinct differences in their germination rates, plant vigour, root morpho-anatomy, pigment contents etc. and Capsicum annuum L.The success of hydroponics in the present study was found to be greatly dependent on the nutrient uptake which was found to be largely controlled by the pH of the medium and best growth was observed with a half-strength Hoagland solution having a pH of 5.8-6.0. The present study was carried out with the objectives of analyzing different hydroponic cultivation techniques and testing their potentialities to be used as a supplement to conventional farming for the cultivation of some vegetable crops like Lycopersicon esculentum Mill., Solanum melongena L.
The hydroponic gardening concepts have been used since ancient times but the concept is gaining popularity only in the recent past especially in the context of acute land crisis and global food security. Hydroponics is a science of growing plants in nutrient solutions with or without the use of an artificial medium for providing mechanical support to the roots. Evaluation of hydroponic cultivation techniques as a supplement to conventional methods of farming. Further, the pilot experimentation in school settings indicates that the comprehensive system design method results in a deployable system, which can become well adopted in the educational domain.Ĭitation: Gurung CT, Bhandari JB, Gurung A. An experiment with nine GrowBots shows that the different parameters can be controlled, that this can control the growth of the food plants, and that control to make an environmental condition with blue light results in higher and larger plants than red light.
The GrowBot system also allows the user to monitor the environmental conditions, such as CO2 monitoring for photosynthesis understanding, on both the touch display and the remote web–interface. This allows school pupils to easily program the GrowBots to different growth conditions for the natural plants in terms of temperature, humidity, day light cycle, wavelength of LED light, nutrient rate, etc. Inspired by educational robotics, we developed user-friendly graphical programming of the GrowBots on several means: a touch display, a micro:bit, and a remote webserver interface. The GrowBot includes sensors for humidity, CO2, temperature, water level, RGB camera images, and actuators to control the grow conditions, including full spectrum lights, IR lights, and UV lights, nutrients pump, water pump, air pump, air change pump, and fan. The GrowBot is a tabletop-sized greenhouse automated with sensors and actuators to become a robotic system for the control of plant’s growth. We present the GrowBot as an educational robotic system to facilitate hands-on experimentation with the control of environmental conditions for food plant growth.
