Abstract
Malus zumi (Matsum.) Rehder is a carrier of powdery mildew resistance genes and also has ornamental traits. However, the variability of its traits is still poorly understood. The aim of the research is establishing the variability and relationship between the 17 traits of the Malus zumi. It was found that the variability of the traits of the flower and fruit is at a very low level, and the traits of the leaf are more variable. There were found strong correlations between the seeds’ weight and its number in the fruit (r=0.83), the diameter and weight of the fruit (r=0.79), and there is a strong inverse relationship between fruit’s weight and anther’s length (r=-0.73). The length of the filament has a strong relationship with the length of the fruit (r=-0.71) and the leaf’s length (r=-0.71), also it is closely related to all leaf traits with a positive relationship. This information is important for the implementation of directed breeding programs, as well as recommendations for use in ornamental horticulture.

Abstract
This article discusses the use of additives from the roots and rhizomes of inulin-containing plants in baking. A method has been developed for the production of bread with the addition of powders of wild-growing inulin-containing plants at a dosage of 1.5%, which makes it possible to obtain a new type of bread while reducing the consumption of baker’s yeast by 10-15%, or reducing the duration of dough fermentation by 15-20%. The content of inulin in 100 g of bread made from wheat flour with the addition of 1.5% to the mass of high elecampane powder is 0.41 g/100 g (S.V.), the fructose content is 0.35 g/100 g (S.V. ). It was found that the added additives do not reduce the microbiological safety of bread. So, QMAFAnM in the sample with high elecampane - 3.5 × 102, in the sample with dandelion officinalis - 1.0 × 102, in the sample with greater burdock 2.3 × 102, which meets the requirements of SanPiN. The quality indicators of powders from roots and rhizomes have been determined, their influence on the technological process of bread production has been studied. A rational dosage was established in the amount of 1.5% by weight of flour, which makes it possible to obtain bread with high quality indicators, increased nutritional value.

Abstract
The article discusses the results of the study of sunflower tester hybrids obtained at the Saratov State Agrarian University according to the scheme: 3 testers - sterile lines and 26 lines - pollinators. Combining ability studies revealed the ranks of OCS and SCS testers, as well as paternal forms. Significant effects of SCS hybrids on the content of fat and protein in sunflower seeds allow them to be considered as a promising breeding material for further study in nurseries of a higher level. It has been established that the frequency of heterosis in terms of fat content is determined by the genotype of parental forms. Line - tester UV 16 b causes a higher frequency and degree of competitive heterosis. According to the protein content, the magnitude and frequency of competitive heterosis practically does not depend on the choice of the tester line. The value of true heterosis in terms of protein content in tester crosses is noted very rarely. A high effect of OCS on fat content was found in the lines: J6 - Slastena, J6 - UN 1313, (KSP-6V), J6 - Krepysh, J6 - Saratov 20 (KSPP-3A). A high dispersion of SCS in terms of fat content was determined in the lines: J6 - Saratov 20 (KSPP-3A), J6 - Malin. Lines with a high effect of OCS in terms of protein content were identified: J6 - Stepnoy 81, J6 - Photon. In breeding for the creation of heterotic hybrids according to the protein content in sunflower seeds, it is advisable to use lines with high SCS dispersion: J6 - Veydelevsky 99, J6 - Natali, J6 -Belgorodsky 94, J6 - Sholokhovskiy.

Published: April 2022

Abstract
The relevance of the topic of the article is due to the increase in the number of adverse climatic phenomena and the strengthening of their influence on the basic branch of agriculture - crop production. The differential manifestation of negative weather factors in the most productive regions leads to fluctuations in yields and agricultural production, disruption of food chains and a decrease in food stocks, thereby jeopardizing sustainable agricultural production and creating risks for ensuring the food security of the Russian Federation. This necessitates the study of regional features of the manifestation of dangerous weather phenomena for the subsequent substantiation of organizational and economic measures to mitigate the consequences and adapt agriculture to global climate change. As an example, we took the Saratov region, as a region with a significant amount of sown (planting) areas and a high share of crop production in the total crop production of the Russian Federation. Using satellite monitoring data, a number of adverse meteorological (weather) phenomena have been established that manifested themselves in the period from 1991 to 2019 in the Saratov region. The tendency to their growth and increase in duration in the territory of the given region is revealed. The dependence of the main indicators of grain production in the Saratov region on the growing influence of negative climatic factors has been studied. The necessity of taking into account the impact of hazardous meteorological (weather) phenomena in the system of strategic priorities, as well as in the preparation of forecasts for the socio-economic development of the region, modeling the impact of negative climatic factors on the structural balance of the agro-industrial complex, is substantiated.

Abstract
Lobster or spiny lobster (Panulirus sp) is a crustacean that is larger than other crustaceans (lobsters). Hong Kong, Taiwan, China and Japan [1]. Indonesia has a sea area of 2/3 of the land, so it has the potential to be utilized for the economy of the Indonesian people, however, the use of marine resources must maintain environmental sustainability [1] Based on the potential of marine waters, it is necessary to take strategic steps to develop lobster cultivation technology to increase production to be able to produce lobsters with high survival and growth. The problem that is still faced when cultivating lobster is the lack of open water environmental studies, the right density, as a place for lobster rearing that is used to approach the state of its environment in nature. The purpose of this study was to obtain optimal density of lobsters in floating net cages (KJA), gain growth (weight and length). This study is an experimental study using a one-factor Completely Randomized Design (CRD) with four treatment levels and three replications to minimize errors, so 12 experimental units are needed. The treatments used in this study were: P0 (10 panulirus/m2), P1 (15 panulirus/m2), P2 (20 panulirus/m2) and P3 (25 panulirus/m2). The results obtained temporarily were PO treatment (stocking density of 10 fish/m2 got the highest weight gain (29, 63 g) and the lowest was P1 (stocking density of 20 fish/m) 25,57 grams. The highest survival rate was P0 (100%) and the lowest was P3 ( 96%), The highest of glucose hemolymph was P2 (78 mg/dL) and the lowest was P0 (23 mg/dL). And the highest of Hemocyte Total Count was P2 (7, 8 ×106/cell) and the lowest were P0 ( 2, 1×106/cell).

Published: April 2022

Abstract
This study aimed to examine the impact of the economic recession due to COVID-19 on 4 aspects of food security (availability, accessibility, stability, and food utilization) in Indonesia. The time-series data (2000-2018) of the Food Agriculture Organization’s statistics were used in this study. The regression equations were analyzed using the Ordinary Least Square estimation technique. The final step was to simulate the impact of COVID-19 on four aspects of food security. COVID-19 had a detrimental impact on Indonesia’s food security. The availability, accessibility, and food stability are aspects of food security that are significantly affected by the COVID-19‘s economic recession, while food utilization is not affected by this pandemic. The worst impact magnitude of COVID-19‘s economic recession was on food stability so that the government needed to increase the implementation of food diversification policies in the future. Also, the government should actively be involved in preventing the increase of the protectionism mainstreaming in the international trade of staple food because it will worsen the food stability in Indonesia as a food importer country.

Published: April 2022

Abstract
The use of transplanters to carry out the planting process has been known widely. Reviews related to productivity performance from these tools are closely related to topographic conditions, soil types, land area, plant species, community culture, the purpose of use, and the technology included as an added value to the tool. Previous studies found various levels of productivity, socio-economic studies, and studies related to users’ demographic characteristics. This study tries to provide an overview of the use of transplanters with a limited scale and on a specific type of soil, studied more comprehensively by considering the community’s demographic characteristics. The results showed that economically, using a transplanter with a limited land area had no significant difference from the traditional method on the soil characteristics. This decision-making was allegedly motivated by the demographic characteristics of farmers. Using a descriptive approach involving 40 respondents, this study found that transplanters do not differ in economic productivity performance on a limited scale.

Abstract
Arbuscular mycorrhizal fungi have the ability to increase nutrient availability for the plant as well as improve the soil quality. However, the effectiveness of AMF is affected by soil fertility. Therefore, this study was carried out to determine the best dose of compound fertilizer for oil palm seedlings with and without AMF application. The factorial experiment (2 × 5) with four replication was carried out with the first factor was AMF inoculation, consisting of 2 levels: without AMF inoculation (m0) and with AMF inoculation (m1). The second factor was compound fertilizer dose, consisting of 5 levels: 0 mg polybag-1 (f0), 250mg polybag-1 (f1), 500 mg polybag-1 (f2), 750 mg polybag-1 (f3), and 1000 mg polybag-1 (f4). The treatments were arranged in a randomized complete block design (RCBD). The data obtained were tested using analysis of variance and means separation tested using Least Significant Difference (LSD) at α 5%. The result showed that oil palm seedlings’ response towards AMF inoculation was influenced by the dose of compound fertilizer based on plant height, leaf surface area, shoot fresh weight, and shoot dry weight. The best dose of fertilizer compound for oil palm seedlings inoculated with AMF was 500 mg polybag-1, whereas without AMF inoculation was 1000 mg polybag-1. In other words, the AMF application reduced 50% of compound fertilizer needed for oil palm seedlings.

Abstract
Coffee plants are one of the important commodities that have a fairly high selling value. Indonesia is one of the largest coffee producing countries in the world with a production of approximately 600,000 tons per year. The application of inorganic (chemical) fertilizers is very important if coffee plants are cultivated on soils that naturally have low fertility. In addition to the level of soil fertility as well, the purity of the planting material must be known from its origin. Because to get optimal results, a superior type or clone of coffee is also needed. This research was conducted at the Lampung State Polytechnic Plantation Plant Entres Garden which is located in Hajimena Village, Natar District, South Lampung Regency with a garden height of 118 m above sea level. This research was carried out in June-October 2021. This study was compiled using a Split Plot Design. Coffee clones were assigned to the main plot and the urea fertilizer dose factor was assigned to subplots. Observational data that has been obtained will be analyzed using analysis of variance (F test) at the 5% level. If there is a significant difference (F count > F table 5%), it will be continued with the Least Significant Difference (LSD) follow-up test with a level of 5%. Based on the results and discussions that have been obtained, it shows that the administration of urea to several Robusta coffee clones gave a significant interaction with the parameters of plant height and stem diameter and clones BP 358 with urea doses of 15 and 20 g gave the best growth compared to other clones.

Abstract
In efforts to increase the production of shrubs pepper with good quality, it is necessary to engineer the physical environment, especially the microclimate and the provision of organic matter to produce quality pepper plants. Weather or climate is a factor that affects plant growth and development. Microclimate includes light intensity, temperature, and humidity. Microclimate modification is changing the environment from unsuitable to suitable. Microclimate modifications include: using shade and giving organic matter can improve soil properties such as texture, moisture and soil temperature. This study aims to: (a) obtain the characteristics of the microclimate, including: temperature, humidity, light intensity that enters the shrubs pepper under one layer (25%) and two layers (50%) shade as well as presenting compost to the growing media, ( b) observing the growth and production of shrubs pepper that were used one layer (25%) and two layers (50%) shade and presenting compost to the growing media, and (c) getting the interaction from using one layer and two layers and presenting compost to the media plant. This study used a randomized block design (RAK) with a factorial pattern with 3 replications. The first factor of shading is 25% (one layer) and 50% shading (two layer). The second factor is the combination of planting media used, namely soil, husk-charcoal soil (2:1), compost-soil (2:1), and husk-compost-charcoal soil (2:1:1). These two factors were applied to the age of one year and two years of shrubs pepper. Data analysis was performed by means of variance (F test) at a 5% significance level, and if there was a significant difference in effect, continued with the Least Significant Difference (BNT) test. Microclimate variables include: (a) light measurements, (b) temperature and humidity measurements, (c) soil moisture measurements. The agronomic variables of shrubs pepper cultivated include: (a) stem diameter, (b) number of branches (c) number of segment, and (d) number of shoot. The results of the observations showed that the using too much shade can be decreased plant growth. The combination of burn husk-compost-soil can be increased stem diameter, number of branches, and number of shoot of shrubs pepper.
