Abstract

The The bambara groundnut has the potential to continue to be developed, but the obstacle faced is the very limited availability of bambara groundnut seeds. This is because there are no varieties from the results of breeding that are released and the low quality of the seeds. Low seed quality is caused by slow germination and results in the seed growth process being non-unison, this is influenced by seed dormancy. The purpose of this study was to determine the effect of soaking time in KNO3 on germination, vegetative morphology, and crop yield in the field by measuring seed viability and vigor, vegetative morphology and yield. The research was carried out for 4 months, from June-October 2022 which took place at the Agrotechnology Laboratory of the Muhammadiyah University of Malang and Dadaprejo Land, Batu City. The study was conducted using a simple Completely Randomized Block Design (RKLT) consisting of 10 treatments, and was repeated 3 times. The observed variables included moisture content, DB, PTM, IV, KCT, T50, plant height, number of leaves, leaf shape, leaf color, stem color, pod color, pod shape, number of pods, pod dry weight, number of seeds, dry weight seeds, yield potential, and weight of 1000 seeds. The results showed that the long soaking of seeds in KNO3 did not affect their vegetative morphology. Soaking time of seeds in KNO3 had no significant effect on DB and PTM values, but had a very significant effect on IV values, the number of leaves in the vegetative and generative phases. And it has a significant effect on the height of the KCT, T50, and plant height in the vegetative phase. As for the yield variable, the results showed no significant effect. Soaking time in KNO3 only affected germination, plant height, and number of bambara groundnut leaves.

Abstract

Vermicast is a used soil from worm maintenance that is product composting from its maintenance in the form of organic fertilizer and it is very suitable for plants. Vermicast contains various ingredients needed by plants that is hormones such as gibberellins, cytokinins, and auxins, and contains of nutrients (N, P, K, Mg and Ca) and Azotobacter sp. which is a non-symbiotic N-fixing bacterium which can help enrich the N element for plants. In the use of vermicast can be solid or liquid. The purpose of this research is to determine the effect of dosage and vermicast with different ingredients of feed as organic fertilizer for shallot. This research was conducted at the FPP Experiment Garden UMM in Tegalgondo Village with a height of ± 560 m above sea level. The study used a Randomized Block Design with two factors. The first factor: worm feed ingredients (K) consist of (K1); Blotong waste (K2); rumen waste (K3); combination of blotong and rumen waste. The second factor: the dosage of administration (U) consists of (U1); 4 Ton / ha (U2); 5 Tons / ha (U3); 6 Tons / ha (U4); 7 tons / ha. This research included nutrient content in vermicast and on the growth of shallot including: Length of plant, number of leaves, number of tubers, weight of fresh plant, weight of dry plant. The results of this research showed that the dosage and feed ingredients given had no significant effect on plant height parameters, number of leaves, weight of fresh plant, and weight of dry plant of shallot (Alium asconolicum L.) for However it was given significant effect for the height parameters of the plant at the age of 13 HST and the number of leaves at the age of 13 HST. And the best is the combination of K3U3 (Vermicast which is given a combination of blotong and rumen waste feed ingredients) with a dosage of 54 grams / plant.
