Abstract

Cassava (Manihot esculenta) cultivation is often carried out with an intercropping pattern with upland rice (Oryza sativa L.) as an intercrop which is expected to increase production and maximize land use. Cassava and upland rice have the same land characteristics, which are planted on dry land so they are suitable for intercropping. The effort used to make land efficient in this system is to adjust the planting time between intercropping plants and the main crop. The purpose of this study was to determine the effect of planting time of upland rice (Oryza sativa L.) on cassava (Manihot esculenta) intercropping. This research was carried out from May to September 2021 in front of Universitas Brawijaya at Mrican Village, Mojoroto District, Kediri City with a place height of 67-100 meters. The study was conducted using a one factor Randomized Block Design (RBD), which is planting time with a combination of 5 treatments and replications. The treatments used included W1: upland rice planting time 14 days before cassava, W2: upland rice planting time 7 days before cassava, W3: upland rice and cassava planted together, W4: upland rice planting time 7 days after cassava , W5 : planting time of upland rice 14 days after cassava. Data were analyzed using variance (ANOVA), if there was a significant effect it was continued with a follow-up test of Honest Significant Difference (BNJ) at 5% significance level. The most appropriate treatment is planting time for upland rice 14 days after cassava, due to the low competition between cassava and upland rice so that cassava and upland rice yields will remain good.

Abstract

The beet armyworm, Spodoptera exigua is a notorious pest that inflicts significant damage to shallot crops, especially leeks, causing leaves to wither due to brown spots and transparency. This issue often leads to excessive chemical control measures, which, in turn, promote insecticide resistance. This study hypothesized that symbiotic bacteria within S.exigua have the capacity to degrade chlorpyrifos-based insecticides. S.exigua samples were collected in Dringu, Gending, and Leces districts, Probolinggo, and subsequently examined for symbiotic bacteria with biodegradation potential. Bacterial exploration and identification were conducted from April to October 2023 at the Pesticide Toxicology Laboratory, Brawijaya University. The study analyzed the clear zone diameter produced by bacteria in media contaminated with chlorpyrifos-based insecticides as an indicator of biodegradation. Out of 41 surviving bacterial isolates, 10 demonstrated notable biodegradation capabilities. The Genus identification revealed that Erwinia sp., Pantoea sp., and Coryneform sp. were among the contributing bacteria. This research emphasizes the potential role of S.exigua-associated symbiotic bacteria in managing chlorpyrifos-resistant pest populations, offering a promising avenue for sustainable pest control methods.

Abstract

Bambara groundnut (Vigna subterranea L.) is a legume plant from Africa. This plant is a promising food crop because it has many benefits regarding nutritional content, health, and agronomic aspects. However, efforts to increase the genetic diversity of potential yields are constrained by the limited genetic resources with high yields. Polyploidy induction increases plant diversity by giving chemical mutagens such as colchicine. This study aims to obtain the optimal concentration for the induction of bambara groundnut plant diversity with the drip method. This research was carried out from May 2022 to July 2022, located in the experimental field and at the Plant Breeding Laboratory, Faculty of Agriculture, Brawijaya University. The treatments used were different concentrations of colchicine, namely K0: 0% (control), K1: 0.1%, K2: 0.2%, K3: 0.3%, K4: 0.4%. The analysis of variance with the 5% level test showed that the colchicine concentration treatment significantly affected all observations of the bambara groundnut plant's quantitative character. The coefficient of the diversity of plants treated with colchicine was higher than the control treatment. The concentration used in this study did not cause the death of 50% of plants, so the LC50 value has not been found. Abnormal plants were found at 0.3% and 0.4% colchicine concentrations with different leaf shapes from the control plants.

Abstract

Sunflower (Helianthus annuus L.) it has high economic potential as a raw material for the food industry and is extracted to produce vegetable oil. The high use of sunflowers causes this plant to be widely cultivated around the world, including in Indonesia. Sunflower production in Indonesia is not enough to meet market needs due to low knowledge related to seed quality. Quality seeds of appropriate size can affect germination and plant growth character. The purpose of this study is to determine the relationship between physical quality and physical character of seeds on the germination of sunflower seeds. The research activity was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, University of Brawijaya Malang in the month of Mare-June 2024. The research was conducted using observation and measurement methods. The variables observed were seed length, seed width, seed thickness, weight of 1000 seeds, seed moisture content, germination power, maximum growth potential, vigor index, growth speed, growth synchronicity, plumula and radicle length. This study uses the analysis of diversity coefficient and correlation coefficient. The results showed that the physical character of sunflower seeds between genotypes had medium diversity and within genotypes had low to high diversity. Physical quality characteristics and physical characteristics of seeds between size groups regardless of genotype, between genotypes, and in genotypes have a positive correlation for all germination characteristics. The improvement in physical quality and seed size was followed by an increase in germination characteristics. Large seeds have a larger embryo size and food reserves as well as enough nutrients to support embryonic development during the germination phase.
