Pengaruh Pemberian Dosis Pupuk kandang Ayam Terhadap Hara N dan Hasil Tanaman Bayam Brazil (Alternanthera sissoo).

Abstract

Brazilian spinach (Alternanthera sissoo) as an introduced plant is still little known and utilized by the wider community. In general, Brazilian spinach is only considered an ornamental plant, even though Brazilian spinach can be consumed and has the potential to be a food security crop. Brazilian spinach leaves can be consumed as food because they contain vitamins A, C, E and iron for erythrocyte regeneration and also have phytochemicals that have the potential to build the immune system. This research aims to obtain the optimal dose of chicken manure for the growth of Brazilian spinach (Alternanthera sissoo). This research was carried out in Deli Tua District, Deli Serdang Regency, North Sumatra Province with an altitude of 59.33 meters above sea level, from June to October 2024. This research used a non-factorial Randomized Group Design (RAK) method with 6 treatments and 3 replications so that 18 were obtained. treatment combination (0; 10; 20; 30; 40; 50 tons/ha). The parameters observed in this research included plant wet weight, root wet weight, plant dry weight, and plant N nutrient uptake. The results of the research showed that giving chicken manure was able to increase the wet weight of the canopy and the dry weight of the canopy. The addition of wet crown weight and shoot dry weight is in line with the increase in chicken manure dose and is still linear so that the optimum dose cannot be obtained. Providing chicken manure can increase the wet weight of the roots. The addition of wet root weight is quadratic so that the optimum dose is obtained, namely 102 g/polybag (equivalent to 40 tonnes/ha). Dosing chicken manure cannot increase N nutrient uptake.
