Utilization of Cow’s Urine and Tofu’s Liquid Waste for Growth of Leucaena Leucocephala Seedlings

Abstract

In the planting program of lamtoro (Leucaena leucocephala), healthy and vigorous seedlings are needed, therefore, it is necessary to apply fertilizer at the nursery stage. The purpose of this study was to determine the effect of tofu's liquid waste and cow's urine on the growth of lamtoro seedlings at aged 6 weeks until 14 weeks. The treatments consisted of control, tofu’s liquid waste (30% and 40%), and cow’s urine (50%, 60% and 70%). Treatment was given every 2 weeks. Parameters observed were height, diameter, number of leaves, biomass, toughness, shoot root ratio, seedling quality index and chlorophyll content. The results showed that 30% and 40% of tofu’s liquid waste had a significant effect on increasing the height growth at 6 weeks and 8 weeks old seedling. The 70% cow’s urine has a significant effect on increasing the height growth at 6 weeks until 12 weeks old seedling. The 60% cow’s urine had a significant effect on increasing the number of leaves.

Effect of Organic Fertilizer on Growth and Productivity of Ipomoea reptans Poir

“…Penelitian Zulfa (2019), menjelaskan bahwa pemanfaatan limbah cair tahu berpengaruh terhadap pertumbuhan Alternantera amoena Voss) hasil terbaik limbah cair tahu terdapat pada perlakuan P3 (60%). Abdillah (2017), perlakuan pupuk AB Mix P0 kontrol menghasilkan pertumbuhan terbaik, Bramasto et al, (2020)…”

“…Pertumbuhan tinggi Ipomoea reptans Poir terlihat berbeda nyata pada hari ke 14 HST hingga 35 HST. Optimalisasi penyerapan unsur hara N sudah optimal pada waktu tertentu (Bramasto et al, 2020). Grafik diatas menunjukan perlakuan P2 lebih dominan pada pertumbuhan tinggi Ipomoea reptans Poir.…”

“…Grafik diatas menunjukan perlakuan P2 lebih dominan pada pertumbuhan tinggi Ipomoea reptans Poir. Penelitian Bramasto et al, (2020), menjelaskan bahwa urin sapi dan limbah cair tahu dapat meningkatkan pertumbuhan. Pemberian konsentrasi 40% (P2) menunjukan pertumbuhan lebih tinggi bila dibandingkan dengan pemberian pupuk kotoran sapi dan limbah industri tahu dengan konsentrasi 20% (P1), 60% (P3), 80% (P4).…”
