PERTUMBUHAN DAN PRODUKSI BAYAM (Amaranthus spp) PADA SISTEM TUMPANGSARI DENGAN SAWI (Brassica juncea) SECARA HIDROPONIK RAKIT APUNG
Abstrak (Bhs. Indonesia)
Penelitian ini bertujuan untuk mengetahui varietas dan tingkat populasi yang tepat untuk pertumbuhan bayam dan sawi, serta produktivitas lahan pada pola tanam tumpangsari. Penelitian dilaksanakan bulan Februari – April 2023 di Experimental Farm, Laboratorium Agroekologi, dan Laboratorium Perlinungan Tanaman, Fakultas Pertanian, Universitas Jenderal Soedirman. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri dari 3 faktor, yaitu monokultur bayam (B), monokultur sawi (S), dan tumpangsari antara bayam dengan sawi (BS). Hasil penelitian menunjukkan bahwa perlakuan varietas berpengaruh terhadap tinggi tanaman, jumlah daun, bobot segar, bobot brangkasan, dan bobot kering, sedangakan perlakuan jarak tanam tidak berpengaruh terhadap pertumbuhan dan produksi bayam. Perlakuan varietas berpengaruh terhadap tinggi tanaman, bobot segar, bobot brangkasan, dan bobot kering, sedangakan perlakuan jarak tanam berpengaruh terhadap tinggi tanaman sawi. Interaksi antara varietas dan jarak tanam berpengaruh terhadap bobot segar bayam serta tinggi tanaman dan jumlah daun sawi.

This research aims to determine appropriate variety and population levels for the growth of spinach and mustard greens, and the productivity of land in intercropping system. The research was carried out from February – April 2023 in the Experimental Farm, Agroecology Laboratory, and Plant Protection Laboratory, Faculty of Agriculture, Jenderal Soedirman University. The experimental design used was a randomized complete block design (RCBD) consisting 3 factors, namely spinach monoculture (B), mustard greens monoculture (S), and intercropping between spinach and mustard greens. The results showed that the variety treatment had an effect on plant height, leaf number, fresh weight, stove weight and dry weight, while spacing treatment had no effect on the growth and production of spinach. Variety treatment had an effect on plant height, fresh weight, stove weight, and dry weight, while spacing treatment had effect on plant height of mustard greens. The interaction of variety and spacing treatment had an effect on spinach’s fresh weight as well as plant height and leaf number of mustard greens.
