Analisa Laju Konsumsi Air dan Nutrisi pada Budidaya Tanaman Kacang Hijau ( Vigna radiata L.) Menggunakan Sistem Fertigasi Irigasi Tetes dengan Media Tanam Cocopeat

Abstract

Water and nutrition consumption rate are affect to growth and yield of plant. This study aims to determine the effect of water and nutrition on the growth of mung bean (Vigna radiata L.) with cocopeat as planting media using drip irrigation fertigation system. Parameter analyzed were evapotranspiration, water consumption rate, nutrition consumption rate, total of seeds per plant, the weight of seeds per plant,weight per seed. The research design is non-factorial completely randomized design. Consisting of 3 treatments and 6 replications. The results showed evapotranspiration was 6,7 mm / day with water consumption rate was 486,6 ml/ day and nutrition consumption rate was 38,638 ml/day. Total of seeds per plant and weight of seeds per plant get the best results at 100% field capacity treatments where total of seeds per plant was 1785 seeds and weight of seeds per plant was 22,78 g/ plant. The best seed weight per grain was treated at 75% field capacity, which was 0.078 g per seed.

Laju konsumsi air dan nutrisi berpengaruh terhadap pertumbuhan dan produksi tanaman. Penelitian ini bertujuan untuk menganalisa laju konsumsi air dan nutrisi tanaman terhadap pertumbuhan tanaman kacang hijau (Vigna radiata L.) pada media tanam cocopeat dengan sistem fertigasi irigasi tetes. Parameter yang dianalisis adalah evapotranspirasi, laju konsumsi air, laju konsumsi nutrisi, jumlah biji per tanaman, bobot biji per tanaman, bobot per butir biji. Rancangan penelitian menggunakan rancangan acak lengkap non faktorial terdiri dari 3 perlakuan dan 6 ulangan. Hasil penelitian menunjukkan nilai evapotranspirasi sebesar 6,7 mm/hari, dengan laju konsumsi air tanaman yaitu 486,6 ml/hari., dan laju konsumsi nurisi 38,638 ml/hari. Jumlah biji per tanaman dan bobot biji per tanaman memperoleh hasil terbaik pada perlakuan 100% kapasitas lapang dengan jumlah biji sebesar 1785 biji dan bobot biji 22,78 g per tanaman. Bobot per butir biji tanaman terbaik yaitu pada perlakuan 75% kapasitas lapang yaitu 0,078 g per biji.
