Abstract

Pepper (Piper nigrum L.) is one of the estate crops with high economic value and a foreign exchange earner for Indonesia, but its productivity is still low. For this reason, nutrient management is essential to increase the productivity of pepper parent plants. This study aimed to obtain the best composition of foliar fertilizer for pepper parent plant growth, obtain the best spraying frequency of foliar fertilizer for pepper parent plant growth, and obtain the best combination of composition and spraying frequency of foliar fertilizer for pepper parent plant growth. The study was conducted from November 2020 to April 2021 using a Randomized Block Design (RBD) with a factorial pattern of 4 × 2. The first factor was the composition of foliar fertilizers with four levels of treatment, namely control (D0), NPK foliar fertilizers 11:8:6 (D1), NPK foliar fertilizer 20:15:15 (D2), and NPK foliar fertilizer 32:10:10 (D3). The second factor is spraying frequency of foliar fertilizer with two levels of treatment, namely every two weeks (F1) and every four weeks (F2). Each treatment was repeated three times and each experimental unit consisted of two parent plants. Observational data was analyze using analysis of variance and continued with the honestly significant difference test (HSD) at the 5% level. The results showed that the composition of NPK foliar fertilizer 20:15:15 with the spraying frequency every two weeks gave a significant effect but did not give the best effect. Significant interactions were shown in the observation variables of number of leaf, number of internode, leaf greenness index, leaf area number three, and leaf dry weight number three.

Abstract

Sugarcane cultivation in dryland is faced with a lack of water availability and low P content in the soil. The technology that is expected to improve the productivity of dry land planted with sugar cane is the use of microbial technology, such as the arbuscular mycorrhiza fungi (AMF) which are synergized with compost planting media as a soil mixture. This study aims to obtain the optimum dose of AMF inoculants, to get the best composition of the planting media, and to get the interaction between AMF inoculant doses on the growth of sugarcane. The study was conducted at the Politeknik Negeri Lampung Teaching Farm from November 2017 to June 2018. The experiment was using a factorial randomized block design with three replications. The first factor is the AMF inoculant dose which consists of four levels (0 g/bucket, 5 g/bucket, 10 g/bucket, and 15 g/bucket); while the second factor is the composition of the compost: subsoil planting media consisting of four levels (0%: 100%, 25%: 75%, 50%: 50%, and 75%: 25%). The results showed the application of AMF inoculants up to 15 g/bucket had not been able to increase the growth of sugarcane. The composition of the planting media 25% compost: 75% subsoil has been able to increase the number of tillers, number of leaves, and stem diameter of sugarcane. There was no interaction between AMF inoculant dose and the composition of the planting media on the growth of sugarcane. Sugarcane requires fertile soil conditions, enough water, and not flooded.

Abstract

Indonesia is one of the world's most enormous vanilla (Vanilla planifolia A.) producing countries. Propagation of vanilla plants by vegetative means using cuttings consisting of 1-3 segments, each node of vanilla has the potential to remove roots and shoots so that with this potential, it is possible for vanilla to be propagated by cuttings. Still, the growing ability is meagre, so special treatment is needed by giving plant growth regulators (PGR). Information regarding using NAA on the growth of vanilla cuttings has not been found. Therefore, this study was conducted to obtain the best NAA concentration for the growth of vanilla seedlings. This research was carried out from July - November 2021 in the experimental garden of the Politeknik Negeri Lampung. The method used was a single factor Randomized Block Design (RBD) with five treatments and five replications, so there were 25 experimental units. The treatment consisted of five levels, namely 0 ppm (R0), 100 ppm (R1), 200 ppm (R2), 300 ppm (R3), and 400 ppm (R4). The data was analysed using the F test. If there is a difference, proceed with the HSD test at the 5% level. The results showed that the 200 ppm (R2) NAA concentration gave the highest average value for several variables, namely, shoot height (16.86 cm), number of leaves (4.68), number of internodes (4.84), and root length (57.05 cm) at the age of 30 DAP to 120 DAP.
