Multi-nutrients deficiency of soil in southwest Ethiopia is among the primary constraints for the very low productivity of potatoes (Solanum tuberosum L.). The combined use of organic and inorganic fertilizers is vital for resolving the common productivity issue. Thus, experiments were performed on potato variety “Belte” in Masha district, southwestern Ethiopia, in both Belg (February to May) as well as Meher (June to October) seasons of 2019 to evaluate the potato response to the vermicompost, mineral phosphorus, and nitrogen’s integrated applications. The experiment had three vermicompost rates with the factorial combination (2.5, 5, 7.5 t/ha) and three recommended rates inorganic NP’s 25%, 50% and 75% (124 kg N/ha and 103 kg P2O5/ha) fertilizer. Results have discovered that 75% inorganic NP and 7.5 t/ha vermicompost’s combined application significantly increase total tuber yield, marketable tuber yield, and individual tuber weight, giving the maximum net benefits and marginal return rate. Thus, it has been discovered from this work that for potato production at Masha area, 7.5 t/ha vermicompost with inorganic NP’s 75% recommended dose’s combined applications are best-integrated nutrient management options.
埃塞俄比亚西南部土壤缺乏多种养分是马铃薯（Solanum tuberosum L.）生产力极低的主要制约因素之一。有机和无机肥料的联合使用对于解决常见的生产力问题至关重要。因此，在2019年的Belg（2月至5月）和Meher（6月至10月）季节，对埃塞俄比亚西南部马沙区的马铃薯品种“Belte”进行了实验，以评估马铃薯对蚯蚓堆肥、矿物磷和氮的综合应用的反应。试验采用因子组合（2.5、5、7.5 t/ha）和三种推荐的无机NP（25%、50%和75%）肥料（124 kg N/ha和103 kg P2O5/ha）进行三种蚯蚓堆肥。结果表明，75%无机NP和7.5t/ha粉丝堆肥的联合施用显著提高了块茎总产量、商品块茎产量和单株块茎重量，使净效益和边际收益率最大。因此，从这项工作中发现，对于马沙地区的土豆生产，7.5吨/公顷的蚯蚓堆肥与无机NP的75%推荐剂量的组合应用是最佳的综合营养管理选择。

The aim of research is to reduce the utilization of water by irrigating the agricultural fields that have low moisture level through the implementation of Wireless Sensor Network (WSN). The ARM-based irrigation solution consists of a Solar Tracking System, Wireless Information Unit (WIU), WSN and Remote Access. The Solar Tracking System utilizes maximum solar energy by using Light Dependent Resistor(LDR) to track the sun. The electric energy produced is stored in the battery which powers the ARM processor. Wireless Information Unit will collect the sensor information from Wireless Sensor Network through the use of Wi-Fi. The system monitors soil-moisture and controls the flow of water using a solenoid valve depending upon the set threshold. In the tank, Ultra Sonic sensor identifies the water level controlled by the WIU. An Android application helps the farmer to monitor the water flow and soil moisture remotely. The proposed water management methodologies for agriculture optimizes the water usage and such practices maintain the crop health, keep yield intact, and avoids human intervention. In this proposed system, soil moisture is maintained appropriately to ensure that a good harvest is obtained which in turn preserves different types of nutrients.

Ferulic acid is a potent antioxidant in rice. The objective of this study was to evaluate the variations in ferulic acid and antioxidant capacity among landrace rice genotypes. The experiment is conducted under paddy field conditions in two locations. It uses a randomized complete block design with three replications, and the treatments consist of 24 landrace rice genotypes. Data are collected for yield and yield components, ferulic acid, and antioxidant capacity. Rice genotypes are significantly different for plant height, number of panicles per plant, number of seeds per panicle, 1,000 - seed weight and grain yield. Grain yields of 24 rice genotypes ranged from 1,476.9 to 4,348.1 kg/ha, and G24 is a good source for high grain yield. Variations in ferulic acid content and antioxidant capacity are found among genotypes. Ferulic acid contents range from 11.56 to 45.68 mg/100 g seed, and antioxidant capacity determined by the DPPH method ranged from 15.46 to 86.26%. G6 has the highest ferulic acid content and antioxidant capacity. These two genotypes are promising for parents in breeding programs targeting improved ferulic acid content, antioxidant capacity, and yield.

A field experiment was conducted at Kediri, East Java, to examine the influence of row spacing on the yield of five promising clones from August 2018-June 2020. The investigation was of a Split-Plot design with three replications. The main plot consisted of three planting arrangements: SR, single row spacing at 110 cm, DR1, double rows spacing 50+135 cm, and DR2, double rows spacing 50+170 cm. Sub-plots consisted of five promising clones and one check variety: MLG 5, MLG 9, MLG 14, MLG 52, MLG 55, and PS 881. The results suggest no overall significant effect of planting arrangement on sugar yield, though clones may vary. There are significant differences in yield between some clones. Wider rows, DR2, show the highest yield in tonnes of cane per hectare (TCH) in PC (153.94 t/ha) with a slight decrease (14%) in RC-1 due to reduced plant population. Sugar yield in tonnes of sugar per hectare (TSH) in various planting arrangements ranges from 12.26-13.99 t/ha in PC and 10.68-11.93 t/ha in RC-1. MLG 9 can be released as a new variety with high cane and sugar yields.
2018年8月至2020年6月，在东爪哇Kediri进行了田间试验，研究了行距对5个有前途的无性系产量的影响。本研究采用裂地法设计，有3个重复。主要地块由三种种植方式组成:SR，单行间距110 cm, DR1，双行间距50+135 cm, DR2，双行间距50+170 cm。子区包括5个有前途无性系和1个检验品种:mlg5、mlg9、mlg14、mlg52、mlg55和PS 881。结果表明，种植安排对糖产量总体上没有显著影响，尽管无性系可能有所不同。有些无性系的产量有显著差异。宽行DR2显示PC的每公顷甘蔗吨产量最高(153.94吨/公顷)，RC-1由于植株数量减少而略有下降(14%)。不同种植安排下的糖产量(吨/公顷)在PC为12.26-13.99吨/公顷，RC-1为10.68-11.93吨/公顷。mlg9可以作为甘蔗、糖产量高的新品种发布。

A high population of Crocidolomia pavonana larvae reduces Brassicaceae crop productivity. To control the pest population, mixed plant extract as botanical insecticides is one of the alternatives. The purpose of this research is to evaluate the joint action between mixed extracts of Azadirachta indica and Barringtonia asiatica seed extracts against C. pavonana larvae and the effect on feeding behavior. The seeds are extracted with ethanol using the maceration method. Bioassays are conducted by a feeding method. Each level of concentration tested and controlled is repeated five times. The concentration-mortality relationship is analyzed using probit. Feeding behavior assayed by choice and no-choice at concentrations equivalent to LC25, LC50, and LC75. The results show the mixture of A. indica and B. asiatica seed extract at a ratio of 3:2.3 has a strongly synergistic action with an LC50 of 0.04% and a combination index of 0.27. The extract mixture at a concentration of 0.02-0.08% is reduced feeding activity 77.16-92.84%. Further research is needed to evaluate the extract mixture in the field.

One essential objective of rice breeding is to obtain high-yielding varieties. This study aims to (1) determine the effect of genotype (G), environment (E), and genotype by environment (G×E) interaction on agronomic traits and yield of 12 lowland rice genotypes, (2) estimate variance components and repeatability (3) identify promising rice genotypes with good agronomic performance and high yield potential. The trials were conducted in three irrigated lowland locations from June to November 2020, using a randomized complete block design with three replications. The results showed that the G×E interaction effect was significant on days to flowering, days to harvest, plant height, number of tillers, and panicle length. The genotype's main effect was significant on yield. Four IPB lines (IPB189-F-13-1-1, IPB189-F-23-2-2, IPB193-F-17-2-3, and IPB193-F-30-2-1) had a higher average yield than Ciherang and Inpari 32 varieties. The IPB189-F-23-2-2 had a panicle length stability across the three test locations and a higher average yield than the checks.

The application of antagonist microbes to control significant diseases on crops is an essential issue in the eco-friendly and sustainable agriculture of the chrysanthemum production system. The application of antagonist consortiums is expected to synergistically suppress the pathogen more effectively than a single microbe, thus increasing the marketable flower yield. The research is carried out to evaluate the single and combined application of antagonists C. ladosporioides and PGPRs, B. subtilis, and P. flourescens to control white rust in Chrysanthemum. The results show that there is no cumulative effect from the combination of biofungicide and the PGPR on disease suppression, disease incidence, and plant growth improvement than single antagonist treatments. Compared to synthetic fungicide, biofungicide and the PGPR treatments give higher parasitism intensity, though the values were negligible among the treatments. The lowest disease intensity is recorded from synthetic fungicide treatment. The improvement of flower quality due to biofungicide, PGPR, and synthetic fungicide treatments was found only on the longer vase life than untreated plants. Observation on the compatibility of antagonists with PGPRs are still needed to increase the effectiveness in controlling white rust in Chrysanthemum.

The study aims to observe coconut shell liquid smoke as a bio-fungicide in controlling F. oxysporum growth. The treatment was applied on sample i.e., coconut shield liquid smoke as a bio-fungicide, compared with a chemical fungicide as a positive control, and without treatment as a negative control. The direct observation was conducted for four weeks, with treatment application every seven days. The analysis of variance test shows the difference of three treatments in controlling the F. oxysporum growth for each observation period. Still, it has no difference in average in fungal growth after treatment. According to the results of weekly observations, coconut shell liquid smoke biofungicide reduces the disease severity on the tapping fields infected by F. oxysporum in the range of 13-21%, whereas chemical fungicide reduces the disease severity in the range of 1-10%. In conclusion, the ability of coconut shell liquid smoke bio-fungicide to control is relatively shorter compared to chemical fungicide. Based on the inhibition ability of coconut shield liquid smoke, it is recommended that utilize various grades of coconut shell liquid smoke as a comparison.

Vanilla planifolia Jacks., is the only commercially cultivated orchid for its compound vanillin. This crop has had serious production limitations due to its susceptibility to Fusarium oxysporum f. sp. vanilla (Fov). Salicylic acid (SA) regulates growth and development processes and induces resistance in plants. Our study evaluated its effect on the growth and development of V. planifolia seedlings grown in vitro and in vivo. A completely randomized design was used with seedlings obtained from nodal segments (2-3 cm long) grown in MS medium with different concentrations of SA (0, 0.25, 5, and 7.5 μmol). An experimental design with four SA concentration treatments (0, 0.25, 0.5, and 1 mmol) and 12 replications was used to evaluate the effects of SA on greenhousegrown plantlets. During four weeks, the number of shoots, length, thickness, number of leaves, number and length roots, chlorophyll and carotene content for both conditions were observed. We found the 7.5 μmol and 1 mmol SA stimulated the growth and development of vanilla plantlets grown both in vivo and in vitro. SA does not affect the content of photosynthetic pigments under any growth conditions.

This crop has had serious production limitations due to its susceptibility to Fusarium oxysporum f. sp. vanilla (Fov). Salicylic acid (SA) regulates growth and development processes and induces resistance in plants. Our study evaluated its effect on the growth and development of V. planifolia seedlings grown in vitro and in vivo. A completely randomized design was used with seedlings obtained from nodal segments (2-3 cm long) grown in MS medium with different concentrations of SA (0, 0.25, 5, and 7.5 μmol). An experimental design with four SA concentration treatments (0, 0.25, 0.5, and 1 mmol) and 12 replications was used to evaluate the effects of SA on greenhousegrown plantlets. During four weeks, the number of shoots, length, thickness, number of leaves, number and length roots, chlorophyll and carotene content for both conditions were observed.

Indonesia is a major producer of palm oil. Consequently, the use of chemical fertilizers has become more extensive. Microalgae represent a potential alternative for enhancing and protecting crops based on their cell elements. This study applies dry biomass or liquid culture formulation of the green microalgae Haematococcus pluvialis to the rhizosphere of oil palm pre-nursery as a biofertilizer. Soil application of microalgae biomass of 0.5 g/l (MA) or liquid culture of 10% (v/v) (BCMA) is carried out to assess its effects on 4-months-old oil palm at the nursery stage. The compatibility test between microalgae and bio fungicide agents in agricultural practices, Trichoderma spp., is also tested on both microalgae formulations. The result shows that both microalgae biomass and liquid culture, alone or combined with Trichoderma spp., give a better growth performance to the oil palm. The application of MA and BCMA result in a maximum increment of plant height, leaves count, and chlorophyll content. Furthermore, the application of BCMA gives better oil palm growth performance, which may probably be influenced by the accessibility of nutrients for microalgae growth. The study reveals that soil application of microalgae as biofertilizers can improve oil palm growth performance.
