“…Brassica Chinensis is sensitive to nitrogen (N) and water stress because it is a leafy plant with a succulent stem (Kamarudin et al, 2014). It requires constant irrigation to achieve optimum production because leaf production is linked to leaf expansion, the most sensitive physiological process to water stress (Paulus et al, 2019).…”

Smart irrigation system is a Precision Agriculture (PA) based device that can automate the irrigation process by analysing soil moisture. The sensor used is a soil moisture sensor that acts as the brain to the system, which will control the whole irrigation system. This research was conducted in the irrigation workshop at UITM Malacca, Jasin Campus, with four treatments and four replications in each treatment. The treatments were T1: manual irrigation (regular planting), T2:40% of soil moisture content, T3:45% of soil moisture content, and T4:50% of soil moisture content. The experimental design used in this study was completely randomized (crd). The parameters involved in this study were plant height, number of leaves, root length, fresh weight, and dry weight of Brassica Chinensis. The data were analyzed using SPSS statistical version 26, and the data analysis involved was average means, analysis of variance (ANOVA), and post hoc test (Bonferroni test). The result shows a significant difference between treatments for plant height, number of leaves, fresh weight, and dry weight parameter since the significance value is less than (0.05), p-value >α, 0.05. While no significant difference between treatments for root length. For all parameter measures of Brassica Chinensis, which was height, the number of leaves, length root, fresh weight, and dry weight shows that T4 had the highest mean, while T2 had the lowest mean. In conclusion, T4 (50% of soil moisture content) was the best percentage to grow a healthy plant.

“…This is in confirmation of the findings of [21], who observed that the highest water use efficiency in terms of marketability was achieved when irrigation led to a 30% depletion of the available soil moisture. [22] have obtained a higher water use efficiency for Chinese cabbage (42.1-47.3 kg m3) in the stress range of 13-17 kappa. As can be observed in Fig.…”

Deficit irrigation is emerging as a promising management practice to reduce water use with marginal loss in crop yield. Further, limited studies are available on the combined effect of water deficit and water quality on the water use efficiency of leafy vegetables like red cabbage in the semi-arid climate of Kirkuk. Therefore, this study was initiated to unveil the combined effect of varying deficit irrigation levels (0.5, 0.75, 1, and 1.2 of full irrigation) and two types of water quality (fresh and saline water) on water use efficiency of red cabbage under drip irrigation with two types of emitters. The results indicated that there is a steady increase in fruit yield with an increase in the level of irrigation with saline water over the entire range of applied water. The highest water efficiency was achieved under the combined effect of fresh water and GR and Turbo emitter when the level of applied water at full irrigation was reduced by a factor of 0.5 (20.31 kg/m3)(21.96kg/m3) respectively Furthermore, crop response factor analysis revealed that the red cabbage can tolerate deficit irrigation and produce satisfactory under both fresh and saline water were GR emitter with fresh and saline water given best value (0.627) (0.703) compeer with Turbo emitter with fresh and saline water given (0.292)(0.566)respectively. Additionally, further research is proposed to study the water productivity of red cabbage with saline water and take into account the yield of the same piece of land when the experiment is repeated for several years.

Description du sujet. Le vers gris (Agrotis ipsilon) est l’un des ravageurs redoutables en cultures maraichères dans les régions tropicales. À Lubumbashi, il s’attaque au chou de Chine (Brassica rapa var. Chinensis) et est responsable d’énormes pertes des récoltes allant de 25 à 50 %.Objectif. L’étude vise à contribuer à l’amélioration de la production maraîchère à travers l’utilisation des biopesticides pour le contrôle d’A. ipsilon dans les exploitations maraichères.Méthodes. Un bloc complétement randomisé avec avec quatre applications et cinq traitements répétés quatre fois (Témoin (T, non traité), Tithonia diversifolia (TD) (extrait aqueux), Tephrosia vogelii (TV), Capsicum pubescens (CP) et Beauveria bassiana (BB) (spores)). Des pièges à phéromones composés de septums en caoutchouc appâtés ont été utilisés pour capturer les A. ipsilon.Résultats. L’application des biopesticides n’a pas influencé les paramètres de croissance du chou, en revanche des différences très hautement significatives ont été observées sur le rendement de chou de Chine. L’intensité d’attaque des bioagresseurs (vers gris) dépend de l’âge de la culture dans le traitement témoin et inversement cette attaque diminue avec l’apport des biopesticides, respectivement de T. vogelii et de C. pubescens. La sévérité (gravité) de l’attaque au niveau de feuilles et l’incidence (influence) de l’attaque des plants sont faiblement observées dans T. vogelii et B. bassiana. Une forte corrélation et positive existe entre la présence de vers gris et les plants morts, de tâches nécrotiques et de feuilles détruites (r= 92 %, 85 % et 80 %). La perforation des feuilles, la chlorose et les feuilles enroulées sont positivement corrélées à l’attaque des vers gris (r= 71 %, 54 % et 42 %).Conclusion. La surveillance a permis qu’un nombre abondant de vers gris soient capturés dans les parcelles de T. vogelii et C. pubescens, mais seul T. vogelii a eu un rendement très élevé que le témoin. L’évaluation des performances économiques des biopesticides s’avère nécessaire afin de disposer d’un référentiel technico-économique solide avant la diffusion de cette technologie auprès des producteurs. Description of the subject. Black cutworms (Agrotis ipsilon) are a major pest for vegetable crops in tropics. In Lubumbashi, they attack Chinese cabbage (Brassica rapa var. Chinensis) and cause huge crop losses, ranging from 25 to 50%.Objective. This study aims to contribute to the improvement of vegetable crop production through the use of biopesticides to control A. ipsilon in farms.Methods. A completely randomized block with four applications and five treatments repeated four times: Control (T, untreated), Tithonia diversifolia (TD) (aqueous extracts), Tephrosia vogelii (TV), Capsicum pubescens (CP) and Beauveria bassiana (BB) (spores). Pheromone traps consisting of baited rubber septa were used to capture cutworrms.Results. This study reveals that biopesticides application did not influence growth parameters in cabbage, although highly significant differences were observed for the yield. The intensity of cutworms attacks depended on the age of the crop in the control group, and decreased with the application of biopesticides (T. vogelii and C. pubescens respectively). The severity of attacks on leaves and their incidence on plants were weakly observed in T. vogelii and B. bassiana. There was a strong positive correlation between the presence of cutworms and dead plants, necrotic spots and destroyed leaves (r= 92 %, 85 % and 80 %). Leaf perforation, chlorosis and rolled leaves were positively correlated with cutworm attacks (r= 71 %, 54 % and 42 %).Conclusion. A higher number of cutworms were caught in the T. vogelii and C. pubescens plots, but only T. vogelii had a higher yield than the control. Evaluation of the economic performance is necessary in order to provide a sound technical and economic reference for biopesticides, prior to stepping up their dissemination to among farmers.
