Efektivitas Boron Berbeda Level Terhadap Pertumbuhan dan Produksi pada Hijauan Indigofera zollingeriana

Abstract

ABSTRAK TIARA DEVIKA. Efektivitas Boron Berbeda Level Terhadap Pertumbuhan dan Produksi pada Hijauan Indigofera zollingeriana. Dibimbing oleh ASEP TATA PERMANA dan IWAN PRIHANTORO. Penelitian ini bertujuan mengukur efektivitas boron dengan level berbeda dalam mendukung pertumbuhan dan produksi Indigofera zollingeriana pada skala lapang. Penelitian ini menggunakan rancangan acak lengkap dengan 4 perlakuan dan 4 ulangan. Perlakuan terdiri dari P0: Penambahan 0 ppm asam borat, P1, P2, dan P3 berturut-turut penambahan asam borat 300 ppm, 400 ppm, dan 500 ppm. Peubah yang diamati meliputi tinggi tanaman, jumlah cabang, jumlah ranting, diameter batang, jumlah daun, berat segar, dan berat kering tanaman. Data dianalisis menggunakan ANOVA dan perlakuan berbeda nyata akan diuji lanjut dengan uji Duncan menggunakan SPSS versi 25. Hasil penelitian menunjukkan bahwa penambahan asam borat level 300-500 ppm efektif dalam meningkatkan pertumbuhan jumlah cabang, jumlah ranting, jumlah daun, berat segar, dan berat kering I. zollingeriana dibandingkan kontrol (0 ppm) pada skala lapang. Namun, pada penambahan asam borat level 300-500 ppm tidak efektif dalam meningkatkan pertumbuhan diameter batang. Penambahan asam borat level 300 ppm merupakan level optimal dalam menghasilkan pertumbuhan dan produksi I. zollingeriana. Kata kunci: boron, I.zollingeriana, pertumbuhan, produksi

ABSTRACT TIARA DEVIKA. Effectiveness of Different Levels of Boron on Growth and Production in Indigofera zollingeriana. Supervised by ASEP TATA PERMANA and IWAN PRIHANTORO. This research aimed to measure the effectiveness of boron at different levels in supporting the growth and production of Indigofera zollingeriana on a field scale. This study used a completely randomized design with 4 treatments and 4 replications. Treatment consisted of P0: Addition of 0 ppm boric acid, P1, P2, and P3, respectively, addition of 300 ppm, 400 ppm, and 500 ppm boric acid. The variables observed included plant height, number of branches, number of twigs, stem diameter, number of leaves, fresh weight and dry weight of the plant. Data were analyzed using ANOVA and significantly different treatments were further tested using the Duncan test using SPSS version 25. The results showed that the addition of boric acid at a level of 300-500 ppm was effective in increasing the growth of the number of branches, number of twigs, number of leaves, fresh weight and dry weight of I. zollingeriana compared to the control (0 ppm) on a field scale. However, adding boric acid at a level of 300-500 ppm was not effective in increasing stem diameter growth. The addition of boric acid at a level of 300 ppm is the optimal level in producing growth and production of I. zollingeriana. Keywords: boron, growth, I. zollingeriana, production
