Abstract
Red chilli (Capsicum annuum L.) is the vegetable commodity that is widely cultivated in Indonesia. Drought stress is one of the factors that limit the growth and yield of the plants. The research to evaluate the morphology and physiology of red chilli and enhancing the growth and the yield under drought stress conditions was conducted in Jam bi City, with an altitude of approximately 35 above sea level. The research was conducted in two phases. The first research aims to get the level of drought stress that affects the growth and yield ofred chilli, and to get varieties of drought tolerant red chilli. The research was done from October 2015 to April 2016, in the Horticulture Seed Centre, Jambi Province, Indonesia. The Split Plot design was used in this research with three replications. As the main plot is drought stress ie: FC (Field Capacity), 75% FC and 50% KL. As subplots are 8 varieties of red chili: Lado, Kastilo, BCA 999, Tanamo, Laris, Romario, Ferosa, and Azimuth. The results showed that the maximum decrease of growth and yield were found under the high level of water stress (50% FC) compared to optimum water supply (FC). The tolerance red chilli varieties will increase the proline content, and maintain the total sugar content and chlorophyll content. Varieties that can survive under drought stress and still provide a high yield is Tanamo, followed by Kastilo, and BCA. The second research aims to improve the growth and yield of red chilli under drought stress conditions and to obtain responsive varieties for the application of foliar fertilizer under drought stress conditions. The research was conducted at Plastic House, Pematang Sulur Subdistrict, Jambi City, starting from February 2017 to July 2017. The study used Split Plot Design. As the main plot is the foliar fertilizer through ie: without fertilizer and without water, 5 ml L·1 foliar fertilizer, and with water. As a subplot is the red chilli varieties of Kastilo (tolerant), Lado (sensitive), and Romario (sensitive). The drought stress used was 50% FC, while the varieties used were varieties derived from the first study. The results showed that the foliar fertilizer application for 5 ml L·1 concentrations increased the growth and yield of red chilli by increasing plant height, branch number, leaf area, shoot dry weight, root dry weight, and total dry weight, and the amount and weight fruit. Foliar fertilizer will increase P and K content, and decrease N, Ca, and Mg. The responsive varieties of foliar fertilizer are the Lado, followed by Kastilo and Romario. Foliar fertilizer under drought stress conditions 50% FC has not been able to give the same results from the FC. Water application through foliar can increase the resistance ofred chilli to drought stress.
