Hasil penelitian menunjukkan volume air 600 ml hari-1 tan-1 optimum dengan media tumbuh tanah + bokhasi pada bobot tanaman segar (1083.33 g) sedangkan volume air 1200 ml hari-1 tan-1 dengan media tumbuh tanah + bokhasi memberikan pengaruh terhadap bobot tanaman kering (95.80 g). Jenis media tumbuh memiliki kapasitas volume air yang berbeda untuk pertumbuhan dan hasil tanaman yang optimal. AbstractThe proper growing media and water volume provide the growth and yield of melon plants. This study aimed to determine the optimum water volume in certain growth media to optimize the growth and yield. The study used a 4 x 3 split plot design with three replications. The main plots were volume of drip irrigations i.e 600 ml day-1 tan-1, 1200 ml day-1 tan-1, 1800 ml day-1 tan-1, and 2400 ml day-1 tan-1 while the sub plots were growing media with three levels i.e soil + husk charcoal, soil + cocopeat, and soil + bokashi. The observed parameters  were plant  height,  leaf number, total plant root length, leaf area, leaf relative water content, proline, stomatal opening width, stomata density, chlorophyll content, flowering age, wet plant weight, dry plant weight, fruit weight, fruit circle, fruit brix, the fruit water content, and NPK content in leaf tissue. The water volume of 600 ml day-1 tan-1 is optimum with growing media soil + bokashi on fresh plant weight (1083.33 g) while the water volume of 1200 ml day-1 tan-1 with soil + bokhasi growing media had an effect on dry plant weight (95.80 g).The types of growing media have different water volume capacities for optimal plant growth and yields.  ","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83034853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Karakteristiknya sebagai tanaman akumulator nitrat perlu diimbangi pemupukan N dan aplikasi Silika (Si) sesuai kebutuhan tanaman. Penelitian ini bertujuan untuk mempelajari interaksi ekstrak silika sekam padi (ESSP) dan N-total, serta memperoleh konsentrasi  ESSP dan N-total yang tepat untuk menghasilkan panen selada yang tinggi tetapi aman bagi kesehatan. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap Faktorial, faktor pertama adalah konsentrasi ESSP (0 ppm, 30 ppm, 60 ppm, 90 ppm) dan faktor kedua adalah konsentrasi N-total (100 ppm, 200 ppm, 300 ppm), setiap kombinasi perlakuan diulang 3 kali. Parameter yang diamati yaitu tinggi tanaman 35 hari setelah tanam (HST), luas daun, berat kering tanaman, berat segar tanaman, kandungan nitrat pada daun selada. Data dianalisis dengan analisis varians taraf 5% dilanjutkan dengan Uji Jarak Berganda Duncan pada taraf nyata 5%, sedangkan parameter kandungan nitrat dianalisis secara deskriptif. Berdasarkan hasil analisis varians konsentrasi ESSP dan konsentrasi N-total berinteraksi pada tinggi tanaman dan berpengaruh mandiri terhadap berat kering tanaman dan berat segar tanaman. Aplikasi ekstrak silika sekam padi 30 ppm meningkatkan hasil panen 28% lebih tinggi dan menurunkan 12% kandungan nitrat tanaman selada pada N total 100-300 ppm.AbstractLettuce is a freshly consumed vegetable. Its characteristics as a nitrate accumulator plant need to be balanced with N fertilization and Silica (Si) applications according to the plant required. This research aimed to study the interaction between rice husk silica extract (ESSP) and total N to obtain the right ESSP and total N concentrations to produce high yield lettuce and safely consumed it. This study used a factorial completely randomized design. The first factor was ESSP concentrations (0 ppm, 30 ppm, 60 ppm, 90 ppm) and the second factor was total N concentrations (100 ppm, 200 ppm, 300 ppm). Each treatment combination was repeated 3 times. The parameters observed were plant height in 35 days after planting, leaf area, plant dry weight, fresh plant weight, and nitrat e content in lettuce leaves. The  data  were  analyzed  by analysis of variance at the 5%, and post-test by DMRT at the 5% significant level, the nitrate content used descriptive analysis. Based on the analysis of variance, ESSP concentration and total N concentration interacted on plant height. The ESSP concentration and total N concentration independently affected plant dry weight and fresh plant weight. Application of 30 ppm rice husk silica extract increased 28% higher yield and decreased 12% nitrate content of lettuce plants at N-total of 100-300 ppm.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91321310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
