Abstract

Long bean plants are a horticultural commodity that has the potential to be developed because they have quite high nutritional and economic value. In order for long beans to grow optimally, organic and inorganic fertilizers can be applied. This research aims to determine the effect of providing organic and inorganic fertilizers and the correct dosage on the growth of long beans. This research used a factorial Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor is the application of Nasa liquid organic fertilizer (LOF) at 4 levels, namely: C0 (0 ml/liter of water/control), C1 (2 ml/liter of water), C2 (4 ml/liter of water) and C3 (6 ml /liter of water). The second factor is the application of NPK fertilizer at 4 levels, namely: N0 (control), N1 (dose 200 kg/ha or 20 g/plot), N2 (dose 300 kg/ha or 30 g/plot), N3 (dose 400 kg /ha or 40 g/plot). The research results showed that Nasa LOF application and NPK fertilizer had a significant effect on plant height at 15 and 30 days after planting (DAP), number of branches at 15 and 30 DAP and flowering age.

Abstract

Oil palm (Elaeis guineensis Jacq.) is a plantation commodity that has become highly favored in Indonesia. The massive expansion of oil palm plantations through large-scale land clearing has created new problems that impact the availability of suitable land for oil palm cultivation, making it limited and difficult to obtain. Consequently, the land currently used for cultivation and nursery is less suitable. Producing high-quality oil palm seedlings is closely linked to maintenance practices, the use of superior varieties, and the growing media used during the nursery phase. The growing media is a significant determining factor as it is the medium in which plant roots develop and absorb various essential nutrients for the plant's survival. In addition to the use of growing media, the application of nitrogen fertilizer aims to increase the availability of nutrients that can be absorbed by the plant for optimal growth. This research aims to determine the effects of growing media and nitrogen fertilizer application, as well as the interaction between these treatments, on the growth of oil palm seedlings in the main nursery. The study employs a factorial Randomized Block Design (RBD) with 2 treatment factors. The first factor is the planting media with 3 levels of treatment (M1: topsoil (3 parts) and rice husk charcoal (1 part), M2: topsoil (3 parts) and compost (1 part), M3: topsoil (3 parts), rice husk charcoal (0.5 part), and compost (0.5 part)). The second factor is the application of nitrogen fertilizer with 4 levels of treatment (N0: control, N1: 4 g/polybag, N2: 8 g/polybag, N3: 12 g/polybag). The results show that the growing media has a significant effect on increasing stem diameter. Nitrogen fertilizer significantly increases plant height and stem diameter. The interaction between growing media and nitrogen fertilizer significantly affects the increase in stem diameter of oil palm seedlings.
