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

Climate change impacts increasing temperature, and environmental factors can affect the capacity and rate of seed germination. This study aimed to determine and study the effect of temperature changes on the viability and vigor of brown rice seeds and the morphology of the sprouts produced. The variation of temperature used was 28-400C, and ten genotypes of brown rice seeds used were Pulen Mudiak, Pulen Kandih, Pulen Marapak, Pulen Talao, 64, Sibandung, Silalang, Timbo Abu, Labuah Baru, and Melayu. The results showed that every 10C increase in temperature affects rice germination percentage. The optimum temperature for the germination of ten genotypes of brown rice tested was a temperature range of 28-330C, with a germination value of >80%, the maximum critical temperature 370C and at 38-40 0C no brown rice seeds germinated. Pulen Marapak has the highest maximum growth potential of 90,3% at 280C and 10% at 370C. The increase in temperature also damages brown rice roots and shoots dengan the average root length is 6,7-10,1 cm and shoot length is 8-11,5 cm at 280C.

Abstract

Research on the effect of Quail Manure on the Growth and Yield of Shallots (Allium ascalonicum L.), has been carried out in Jorong Lima Ninik, X Koto Singkarak District, Solok Regency with an altitude of ± 400 m above sea level. This study aims to obtain the best dose of quail manure for the growth and yield of shallots. The method used was a Randomized Block Design (RAK) with 6 treatments, 4 groups. The treatment given was the dose of quail manure namely, as follows: P1=0 g/polybag, P2=30 g/polybag, P3=60 g/polybag, P4=90 g/polybag, P5=120 g/polybag, P6=150 g/polybag. The research data were analyzed for variance if the calculated F was greater than F table 5%, followed by Duncan's New Multiple Range Test (DNMRT) at a 5% significance level. Parameters observed were plant height (cm), number of leaves (strands), number of tubers (fruit), wet weight (g), dry weight (g). The results showed that the application of quail manure had a very significant effect on plant height, the number of leaves, wet weight, and dry weight of shallot bulbs. The best results were obtained from the P5 treatment (120 g/polybag) with a production of 78.25 g/plant.

Abstract

Vegetative growth of citrus can be increased through a combination of fertilization and pruning. Borneo Prima Mandarin (Citrus reticulata cv Borneo Prima) is a superior local commodity that is grown in lowlands. It has an interesting orange skin, while normally the tropical lowland citrus has a green skin colour. As a new commodity, Borneo Prima Mandarin has to be developed in order to increase production and improve quality. There is no specific cultural practices, so it needs to be developed, especially on fertilizing and pruning. The first experiment aims to observe the plant growth and architecture of plants grown in the orchard. The first factor was the nitrogen fertilization rate (0, 20, 40, 60 g N per tree per application) and the second was pruning (without pruning, open center pruning, hedge pruning). In the second experiment, the plants were applied with the same factors of experiment 1, but were grown on a root observation chamber sized 40 x 20 x 60 cm (length x width x height) which aims to observe the shoot root’s growth and the plant’s biomass. Nitrogen fertilizer had a significant effect to the growth of the Borneo Prima Mandarin, i.e number of shoots and leaves. Twenty grams of nitrogen fertilizer per aplication was efficient to produce new shoots and leaves. Pruning treatments had significant effects towards the plant architecture (i.e reducing plant height, canopy shade projection and canopy length). Open center pruning and hedge pruning made the crown more open which increased the light interception. The shoot grew rapidly two weeks after fertilizing and also pruning. While the root grew rapidly after shoot dormancy.

Abstract

Salt stress adversely affects the physiological processes of plants, causing negative changes in the morphology and anatomy of cells, tissues and organs. In order to adapt to the increasingly complex situation of saline intrusion, application of exogenous plant growth regulators shows many positive results to improve the crop's tolerance. In order to survey the effects of humic acid and salicylic acid on yellow hot chili (Capsicum annuum L.), the study was experiated in the greenhouse of Kien Giang University. The experiment was arranged in a completely randomized design, including 2 factors: humic acid (with 4 concentrations: 0 ppm, 1,000 ppm, 1,500 ppm and 2,000 ppm) and salicylic acid (with 4 concentrations: 0 mM, 1 mM, 1.5 mM and 2 mM) were treated separately or in combination (including 16 treatments with 3 replicates). The results showed that the yellow hot chili could grow and bear fruit when watered with saline water from 30 days after planting, however, the yield was low. The record indicated that supplying humic acid at 1,500 ppm into the soil and spraying with salicylic acid at 2 mM to the leaves gave the most effective results, increasing 82% of the yield compared with the control.

Abstract

Potatoes are one of the world's five food crops in the form of tubers and have many benefits. One type of potato developed in Indonesia is red potatoes because they have a high nutritional content and are more susceptible to plant pest organisms. An experiment was conducted in Nagari Selayo Tanang Bukit Sileh, Lembang Jaya, Solok, West Sumatra, Indonesia from May to August 2017. The effect of three indigenous rizobacteria (A2.1b2, A3.1a5 and B1.2a2) and three types of manure, both individually and in combination, on the growth and yield of red potatoes was studied. A two way factorial experiment with a completely randomized design and three replicates was used. Chicken, quail and cattle manure were applied at a dose of 30 tons per hectare. Data were analyzed by analysis of variance and comparison of mean using the Honestly Significant Difference test at the 5% level. There was no interaction between rizobacterial isolates and manure on the growth and yield of red potatoes. All isolates gave similar results with respect to plant growth, but isolates A2.1b2 give the best yields. Chicken manure increased fresh weight of tubers by 11.73 ton per hectare compared to quail and cattle manure.

Abstract

This study aims to obtain the composition of soil and cow dung that provides the best growth for kepok banana seedlings using banana corm.. This research was conducted in Sijunjung Regency. Efforts to provide banana seeds are carried out by utilizing banana corm which will produce 3 and 4 tillers per tuber and the production time is much faster than seeds from tillers. To get the best banana corm growth, a study was conducted using a mixed planting medium of soil and cow manure with five comparisons. The treatments were: A. Soil with cow manure 1:1 ratio, B. Soil with cow manure 2:1 ratio, C. Soil with cow manure 3:1 ratio, D. Soil with cow manure 4:1 ratio, E .Soil only. The treatment was repeated 5 times. The design used was a randomized block design and continued with DNMRT (Duncan New Multiple Range Test). Parameters observed were when shoots appeared, percentage of growth, shoot height, stem diameter, number of leaves, leaf length, root length and number of roots. The results showed that the best planting medium for planting banana kepok from corm was a medium consisting of soil and cow manure with a ratio of 1:1. This treatment gives the best results for all parameters.

Abstract

Weed Eleusine indica L. was reported to have been difficult to control using glyphosate in Oil palm plantation during the time. Sulfentrazone was used as an alternative herbicide for the management of resistant weeds. The aim of this study was to determine the effects of two active ingredients Glyphosate and Sulfentrazone on weed Eleusine indica L. resistant to herbicide. The study was conducted using Completely Randomly Designed (CRD) with 14 treatments and 3 replications. 14 treatments consisted of single herbicide Glyphosate, which was applied at field rate 2 l/ha, Sulfentrazone was sprayed at the numerous dose of 500, 750, 1000, and 1250 ml/ha, and the mixture of Glyphosate and sulfentrazone at the dose of 500 ml/ha + 2 l/ha and 750 ml/ha + 2 l/ha, respectively. The research was conducted at the Greenhouse of the Faculty of Agriculture, Andalas University, Padang, from August to December, 2021. The results showed that there were significantly effect when used in combination of herbicides Glyphosate and Sulfentrazone, showed 100% of mortality weed after 3 week application. For a single active ingredient, Glyphosate controlled eficiently weed at the 4-leaf stage, Sulfentrazone had same impact on managing weed on the 4 and 6-leaf stage, both caused 100% weed dead. However, weed Eleusine indica L. was treated with Glyphosate still survived on 6 and 8 leaves weeds. Similar to Glyphosate, Sulfentrazone could not completely control resistant weeds at the 8-leaf stage. Classification of resistant weed Eleusine indica L. are herbicide-developing resistance 14%, herbicide-resistant 22%, and herbicide-susceptible 64%.

Abstract

Areca nut is one of Indonesia’s leading export commodities that must adhere to certain phytosanitary requirements, including being pest-free. It is infested by several types of insect pests during the storage process. Therefore, this study aims to determine the diversity of warehouse pests that infest areca nuts. It was conducted using a survey method at three warehouses of large collectors and exporters of areca nut in the Padang city and the Padang Pariaman regency. The purposive sampling method was adopted to collect samples from three traders' warehouses. Furthermore, the nut was taken diagonally in a pile, namely the corner and center of 1 kg each, and repeated 4 times. The identification key was used to identify 15 insect types from 10 families and 3 orders. The Cryptolestes pusillus, C. ferugineus, and Carpophilus sp. were found with the highest number of individuals in each warehouse. The diversity index of the three warehouses is 1.78, 2.14, and 1.90 indicating a moderate level. Additionally, the similarity index between warehouses shows a high and very high level of species similarity.
