Growth Response Of Pakcoy Mustard (Brassica Rapa L.) Mustard Plant Production With The Hydroponic Model Of The Wick System To Salinity Stress Conditions Respon Pertumbuhan Produksi Tanaman Sawi Pakcoy (Brassica Rapa L.) Dengan Model Hidroponik Sistem Sumbu Terhadap Kondisi Cekaman Salinitas

Abstract

The current decline in productivity and agricultural output is also a result of high salinity levels. As much as 20% of 50% of irrigated land worldwide is affected by varying levels of salinity. The purpose of this study was to determine the growth response of the wick system of hydroponic pakcoy mustard greens to salinity stress conditions. This research was conducted in Pabean Hamlet, Kejapanan Village, Gempol District, Pasuruan Regency, starting from September to October 2020. The experiment was arranged in a randomized block design (RAK) with 6 treatments consisting of 0, 1000, 1500, 2000, 2500, and 3000 ppm. The treatment was repeated three times, so that 18 experimental units were obtained. Each experimental unit consisted of 12 plants. The data were analyzed using ANOVA at the 5% level followed by the 5% BNJ test. The variables observed were plant height, number of leaves, leaf area, wet weight, consumption weight, and chlorophyll test with a wavelength of 649 and 665. The results showed that there was no significant difference in each treatment unit. From these results it can be concluded that pakcoy mustard plants do not respond to salinity stresses of up to 3000 ppm.
