Increase of phytomass and protein in hydroponic green forage through fertilization in Casanare, Colombia

Objetive. To evaluate the effect of two types fertilizers on phytomass and protein content hydroponic green forage (FVH) corn (Zea mays L.), rice (Oryza sativa L.) soybean (Glycine max L.). Design/methodology/approach. A 32x32 bifactorial design was implemented. The seeds were disinfected with 1 % chlorine by immersion for 15 min. system nebulization irrigation used frequency every 4 hours 5 cm3 organic fertilizer (FO) inorganic (FI) applied per liter water. Plant height (cm), fresh production (kg), real yield (kg.kg-1.m2) crude (%) measured. data analyzed means an ANOVA comparison Tukey test (p ≤ 0.05) SPSS statistics 24. Results: With 7,102 kg seed, a 50.7 kg.m2 FVH 17 obtained; seed yields 30.53 15% are 19.17 38% protein. Limitations study/implications: nitrogen in can be considered main factor quality. Findings/conclusions: Inorganic fertilization has significant FVH.
