Citrus is one of the horticultural commodities that has been a focus of development in 2018. Citrus is the fourth largest commodity in the percentage of Indonesia fruit production in 2014. In 2014, citrus fruit production in Indonesia was 1,785,256 tons or around 9.01% of national fruit production. Karo Regency is a citrus production center in North Sumatra, Indonesia. According to the Direktorat Jendral Hortikultura (2015) the production of citrus commodities was 173.921 tons (53,30%). In 2014, there were 3,150,060 productive citrus trees with a harvested area of ​​7,875 ha and a production of 500,243 tons in North Sumatra. One of the varieties grown by farmers in Karo Regency is Siam. High productivity of siam is certainly also influenced by seedlings, fertilization and controlling the pests. To determine this, research has been conducted on farmers in Simpang Empat and Payung Districts, Karo Regency, North Sumatra, Indonesia. To get quality Siam seeds, farmers in two research locations used Japansche citroen plants as rootstock because they were resistant to disease and drought. Fertilization of siam uses inorganic fertilizer as much as 3-4 months, while organic fertilizer as much as 10 months. The control of pests of siam citrus is done mechanically and chemically. Pests and diseases that usually attack siam are Bractocera spp, black lice, fruit borers, fungus and powdery mildew.  Keywords: cultivation, seedling, fertilizer, pest, productivity, orange, Citrus nobilis

The French citrus industry in Algeria grew rapidly in terms of land area and fruit production from the 1930s until Algerian Independence in 1962. This article contends that technical expertise regarding citrus cultivation played a role in colonial control of Algeria’s territory, population, and economy. The French regime enrolled Algerian fruit in biopolitical interventions on rural ways of life in Algeria and urban standards of living in France. Technical manuals written by state-affiliated agronomists articulated racial distinctions between French settlers and Algerian peasants through attention to labor practices in the groves. A complex legal, technological, and administrative infrastructure facilitated the circulation of citrus fruit across the Mediterranean and into metropolitan France. This nexus of scientific research, economic profit, and racial hierarchy met criticism during the Algerian War for Independence. In the aftermath, expert discussions about citrus production reflected uncertainties and tensions regarding Algeria’s future. Citrus’ place in scientific, technological, and economic changes in twentieth-century Algeria illuminates the politics of technical expertise under colonialism and during decolonization.

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound

Red Currant

Powdery mildew is one of the most harmful fungal diseases that causes economically significant damage to berry plantations. The disease is common in all areas of currant cultivation in the Russian Federation. In this regard, in modern conditions of intensive berry growing, the problem of breeding cultivars that are highly resistant to diseases and pests becomes urgent. Breeders have a difficult task to combine the adaptive potential of the cultivar with its annual high productivity and resistance to biotic environmental factors. When studying the adaptability of introduced cultivars of red currant and selected forms of the Institute to local soil and climate conditions, the following cultivars were identified as sources of economic and useful characteristics and involved in selection: ‘Belaya Potapenko’ as a complex source of resistance powdery mildew and high marketable and taste qualities of berries; SS 1426-21-80 as a source of high productivity and long racemes (raceme length 11-13 cm; up to 20 berries in the raceme). On their base the selection family of red currant has been developed: Belaya Potapenko × ♂SS 1426-21-80. The study of data on the destruction of hybrid seedlings of the selection family by powdery mildew showed that in epiphytotic conditions, the percentage of intensity of the disease development varies over the periods of screening from 0.2% in May to 20.4% in June. Such indicators served as a prerequisite for conducting a comparative test of breeding material in the field under artificial infection with powdery mildew. After artificial infection on the background of epiphytosis, the rate of intensity of the disease development increased slightly and amounted to 35.6% for the family. There were 30 highly resistant seedlings in the family, 10 of which have remained stable and highly resistant since 2018. In these plants we can assume the presence of the so-called field resistance, controlled by polygens, each of which does not give a visible effect of stability, but with different combinations determines one or another of its degree. Highly resistant seedlings will be used in further breeding studies to identify new sources of resistance to powdery mildew.

ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

Application of right dosage of fertilizer and concentration of plant growth regulator are supporting factor of clove growth. This study was aimed to obtain the best combination of organic-inorganic fertilizer, the best triacontanol concentration and both interactions for increasing clove growth. This study used a Randomized Complete Block Design (RCBD) with two factors. The first factor was the organic-inorganic fertilizer dosage package that consisted of 6 levels, i.e no fertilizer, 100% recommended dosage of inorganic fertilizer (r.d.i.f), 25% recommended dosage of organic fertilizer (r.d.o.f) + 75% r.d.i.f, 50% r.d.o.f + 50% r.d.i.f, 75% r.d.o.f + 25% r.d.i.f, 100% r.d.o.f. The second factor was the concentration of triacontanol that consisted of 3 levels, i.e no triacontanol, 2 mg L-1 and 4 mg L-1. The results showed that the application of 25% r.d.o.f + 75% r.d.i.f produced the best clove growth, but it was not significantly different from the combination treatment of the two other types of fertilizer as indicated by the greatest improvement on stem diameter, branches number, leaf area, chlorophyll a, chlorophyll b, total chlorophyll and carotenoids. Clove plants did not respond to the application of triacontanol at a concentration of 2 mg L-1, but gave a negative response to the application of triacontanol 4 mg L-1 on the plant height and leaf area variables. The interaction of the two factors did not have significant effects on all variables. Keywords: chlorophyll, morphology, nutrient dynamics, physiology, vegetative growth
