Abstract

Increasing the genetic diversity of plants can be done through physical mutations with gamma-ray irradiation. This study aims to determine gamma-ray irradiation on the growth of six M1 generation black rice accessions. This research was conducted in May-October 2019 at the Experimental Rice Fields of the Tasikmalaya Perjuangan University, West Java. The materials used in this study were six accessions from Tasikmalaya (PH, PH2, PH3, PH5, PH7, and PH8) without 0 Gy irradiation and with 200 Gy gamma-ray irradiation of M1 generation. The results showed that gamma-ray irradiation reduced germination characteristics, seedling height, and flowering age. Some of the accessions showed different effects; there were a decrease and an increase in the characters of root length, plant height, number of productive tillers, number of unproductive tillers, and the total number of tillers.

Abstract

One of the main products of sunflower is the seed which is a producer of vegetable oil that is needed in the pharmaceutical industry and the health sector. The price of sunflower seed oil is currently very high for the market but sunflower production in Indonesia is quite low. This potential can be used as the basis for the development of sunflower cultivation in Indonesia. One of the efforts to increase the content of sunflower seed oil is to improve proper cultivation techniques and modifications in cultivation techniques. One of the cultural techniques in increasing production is to get the right dose of nitrogen (N) fertilization. The addition of Arbuscular Mycorrhiza Fungi (AMF) is expected to increase the absorption of N nutrients in the soil, thereby increasing the growth and yield of sunflowers. This study aimed 1) effectivity of AMF and nitrogen fertilizer application with various doses on growth and yield of sunflower, 2) to obtain the right dose of N fertilizer on growth and yield of sunflower The study used a Split-plot Design with 3 replications. The first factor as the main plot is AMF i.e. F0 = without AMF, F1 = with AMF 5 g hole-1. The second factor as a sub-plot is the dose of urea fertilizer with 4 levels i.e. N1 = 50 kg N Ha-1, N2 = 100 kg N Ha-1, N3 = 150 kg N Ha-1, N4 = 200 kg N Ha-1. Observations data were evaluated by analysis of variance if the obtained F count was greater than F table 5% followed by a further test of DNMRT at the 5% significant level. Result showed 1) the effectivity of AMF and nitrogen fertilization on sunflowers was able to increase the number of leaves, accelerate the initiation of flowering, increase the diameter of sunflowers, total seeds per plant, the weight of 100 seeds, and seed production per plant, 2) Economically, the application of nitrogen fertilizer with a dose of 150 kg N Ha-1 is more appropriate in increasing the growth and production of sunflowers

Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.

Abstract

Organic matter has an important role besides providing macro and micro nutrients to plants, it can also improve environmental quality. The fermentation of rabbit urine and coconut water is expected to optimise the growth of honje seedlings. The aim of this study was to determine the concentration of fermented rabbit urine and coconut water that can optimise the growth of honje seedlings of Tasikmalaya accession. The study used a completely randomised design with seven treatments, namely A = control, B = 25% rabbit urine fermentation, C = 50% rabbit urine fermentation, D = 25% coconut water, E = 25% rabbit urine fermentation + 25% coconut water, F = 50% rabbit urine fermentation + 25% coconut water, G = 50% rabbit urine fermentation + 50% coconut water. The results showed that the treatments gave significantly different results on shoot emergence, seedling height, seedling diameter, and root crown ratio. Treatment G produced the fastest shoot emergence (6 days), and plant height (10.4 cm). Meanwhile, the widest seedling diameter was produced by treatment B (4.4cm), C (3.9 cm), and treatment G (3.9cm). Treatment C produced the highest root crown ratio of 0.5.
