Supervising Plant Growth in a Greenhouse
(IEEE, 2022-11-30) Alexander, D.L; Hathnapitiya, G.A.G.; Gamage, A.I; Bandara, P.M.P.C; Giragama, G.W.M.N.U.I.B; Supunya Swamakantha, N.H.P.R
Since the beginning of civilization, agriculture has played a significant part in the economy of a nation. Currently, as the population continues to increase at a rapid rate, arable lands are dwindling alongside urbanization. Even though farmers devote a substantial amount of time and effort to farming, environmental factors such as seasonal shifts can have a significant impact on the crop. Smart agriculture is implemented to boost the production of high-quality goods and address the lack of control over the farming process. The intelligent greenhouse technology proposed here is called “GSense,” and it could boost plant productivity by managing the greenhouse’s climate. In addition, this solution is useful for novices who are just beginning out in agriculture because it can make recommendations to its user. The execution of the solution is complemented by a mobile application and a desktop application via which the user may submit inputs and examine real-time sensor data

Plant growth flowering and fruit formation of tomato grown under protected culture
(Postgraduate Institute of Agriculture, University of Peradeniya: Peradeniya, 1998) Weerakkody, W. A. P; Peiris, C. N
Protected culture is a remedy for environmental problems of crop cultivation. However, seasonal weather changes adversely affect indoor grown plants. Therefore, this study was conducted to examine the affect of protected (indoor) culture and other improved technologies, often used in protected culture, on tomato (Lvcopersicon esculentum L.) grown with irrigation during the Maha season. Two indoor cultures together with improved technology and two outdoor (open-field) cultures with and without improved technology were used as treatments. Vegetative and reproductive growth of tomato were evaluated during the respective growth stages. Except at early vegetative growth, dry weather prevailed during the cropping season. Most of the vegetative growth parameters were not significantly different between the indoor and outdoor treatments. However, indoor culture showed significantly higher flowering and fruit formation. The shed house recorded the highest number of fruits per plant. Significantly higher vegetative growth was observed with the use of improved technologies, irrespective of the experimental conditions. Moreover, the improved technologies contributedfor greater number offlowers per plant but not for number of fruits. Indoor culture in combination with the improved technology assured greater vegetative growth, flowering and fruit formation of tomato when compared to outdoor culture under low rainy conditions that prevail during the Maha season. Except for fruitformation, comparative advantages of different indoor structures were not evident.
