Tanggap Pertumbuhan dan Hasil Tanaman Sawi Pagoda (Brassica norinosa) Terhadap Berbagai Dosis Pupuk AB MIX Metode Hidroponik dengan Sistem Rakit Apung
'Universitas PGRI Palembang', 2020Co-Authors: Dahlianah Inka, Arwinsyah Arwinsyah, Sari, Pebriana Kartika, Rahma, Suhal NurAbstract:The purpose of this research to find a suitable dose of ab mix for pagoda Mustard Plant, has been carried out on Jalan Sukakarya, Sukarami, Palembang. The trial was conducted in October to December 2019 who have used a perfectly randomized design method is a single factor group with 5 treatments and 4 replications. Each treatment consisted of 3 Plant so there was 20 and a total of 60 Plants. This was the dose of AB mix fertilizer (D), namely D1 = 850 ppm, D2 = 1050 ppm, D3 = 1250 ppm, D4 = 1450 ppm, and D5 = 1650 ppm. The observed parameters were Plant height, root length, and wet basis, measured at the end of the study. The results showed that the highest yield of D3 treatment was obtained at root length and Plant wet basis respectively of 15.77 cm and 149.97 g and the highest yield of D4 treatment was obtained on Plant height parameters of 12.91 cm, and the lowest yield was very significant in D5 respectively 9.24 cm, 9.57 cm and 112.50 c

allelopathic effects of black Mustard brassica nigra on germination and growth of wild barley hordeum spontaneum
Journal of Agronomy and Crop Science, 2003Co-Authors: A M Tawaha, M A TurkAbstract:Black Mustard [Brassica nigra (L.) Koch.] contains water-soluble allelochemicals that inhibit the germination and growth of other species. This characteristic could be used in weed management programmes. Greenhouse and laboratory experiments were conducted to determine the effects on wild barley (Hordeum spontaneum Koch.) germination and seedling growth of (i) preceding crops, (ii) fresh black Mustard residue incorporation, and (iii) black Mustard leaf, stem, flower and root water extract concentrations. Growth of wild barley, as indicated by Plant height and weight, was significantly reduced when grown in soil previously cropped to black Mustard compared with that cropped to wild barley. Soil incorporation of fresh black Mustard roots and both roots and shoots reduced wild barley germination, Plant height and weight when compared with a no-residue control. In bioassays, black Mustard extracts reduced wild barley hypocotyl length, hypocotyl weight, radicle weight, seed germination, and radicle length by as much as 44, 55, 57, 63 and 75 %, respectively, when compared with a water control. Increasing the water extract concentrations from 4 to 20 g per 100 ml of water of all black Mustard parts significantly increased the inhibition of wild barley germination, seedling length and weight. Based on 8-day-old wild barley radicle length, averaged across all extract concentrations, the degree of toxicity of different black Mustard Plant parts can be ranked in the following order of inhibition: leaves > flowers > mixture of all Plant parts > stems > roots.

first report of branched broomrape orobanche ramosa on oilseed rape brassica napus wild Mustard sinapis arvensis and wild vetch vicia spp in northern greece
Plant Disease, 2011Co-Authors: J T Tsialtas, I G EleftherohorinosAbstract:Branched broomrape (Orobanche ramosa L.) is a chlorophyll-lacking, root parasitic Plant that infects many crops and wild species (2). Plants are densely hairy with minute, glandular hairs, particularly on flowers and upper stems. Stems are erect, often branched just above the ground, and brown to straw yellow. Leaves are sparse, triangular, dark brown or purple, and arranged alternately mainly near the base of the stem. Flowers are numerous, arranged along an upright spike with a lance-shaped bract beneath the flower (about a third of the length of the flower). Petals are pale blue to purple and united into a slender tube approximately 15 mm long with two lips, the upper divided into two lobes and the lower into three lobes. The flowers have two short and two long stamens. During 2010 and 2011, a severe broomrape infection was found in an oilseed rape (Brassica napus L., cvs. Nelson and W31) crop on light-textured soil in northern Greece (Paralimnio-Serres, 41°01'N, 23°32'E, 40 m above sea level), where oriental tobacco (Nicotiana tabacum L.), a susceptible host of branched broomrape, was grown 20 years ago. The field had been cultivated with oilseed rape for three consecutive seasons in rotation with sunflower (Helianthus annuus L.). The infestation of the oilseed rape crop was confirmed in April by digging in the soil (25 to 30 cm deep) to verify attachment of the broomrape to roots of the crop Plants. Density of the broomrape ranged from 20 to 120 stems per m2 and broomrape stems were 15 to 30 cm tall. Yield losses were estimated at 30 to 60%. In 2011, branched broomrape was found parasitizing wild Mustard (Sinapis arvensis L.) growing as a weed in the oilseed rape field. Attachment of the broomrape was verified on a lateral root of the wild Mustard Plant near the soil surface, 0.95 m from the main root of the weed. Additionally, branched broomrape was found in April 2010 and 2011 parasitizing wild vetch (Vicia spp.) growing in field margins at the Cotton and Industrial Plants Institute-National Agricultural Research Foundation (Sindos, 40°41'N, 22°48'E, 17 m above sea level). The parasitized vetch Plants were growing on light-textured soil. Attachment of the broomrape to roots of the host Plants was verified at a 5-cm soil depth. Stems of the parasite were short (7 to 10 cm). The monthly mean air temperature for February (7.3°C), March (9.6°C), and April (14.1°C) and mean soil temperature at a 10-cm depth for February (7.0°C), March (9.5°C), and April (13.4°C), before verification of the broomrape infestation at Sindos, were much lower than the temperature range reported (18 to 23°C) for branched broomrape infestations (1). To our knowledge, this is the first report of O. ramosa on oilseed rape, wild Mustard, and wild vetch in northern Greece. Since branched broomrape could be a significant parasite for oilseed rape, which was introduced to Greece as a commercial crop 5 years ago, measures should be taken to avoid significant yield losses from this parasitic Plant.

PENGARUH BERBAGAI MACAM DAN DOSIS PUPUK ORGANIK CAIR TERHADAP PERTUMBUHAN DAN HASIL TANAMAN SAWI PAGODA (Brassica narinosa L)
AGRONISMA, 2021Co-Authors: Sidiq, Faizal Arba'iAbstract:Pagoda Mustard Plant (Brassica narinosa L.) is a Plant of the brassicaceae family that has a beautiful shape. In increasing the growth and yield of organic pesticide-free Mustard greens, one of them is by providing liquid organic fertilizer. Liquid Organic Fertilizer (LOF) of golden snail meat which contains nitrogen and banana weevil which contais phosphate are organic materials that can be used for organic liquid fertilizer needed by vegetable Plants. The purpose of giving liquid organic fertilizer in this research was to determine the effect of growth and yield of pagoda Mustard Plants, to find out the best results between the two types of liquid organic fertilizers and to obtain the optimal dose obtained at the dose of the two liquid organic fertilizer. The design used in this research was a 2 factorial Randomized Block Design (RBD). The first factor is the type of LOF material (Golden snail meat and banana weevil), the second factor is the dose of LOF given (50ml/polybag, 100ml/polybag, 150ml/polybag and 200ml/polybag). The result of reseacrh on the growth of the pagoda Mustard Plant showed that the combination of P1D4 (Golden Snail Liquid Fertilizer 200ml) gave the best result at the 28 dap in the number leaves obtained. On harvesting the pagoda Mustard Plants separately, the LOF at D4 (200ml/polybag) had a significant difference with the others. Between the application of Liquid Organic Fertilizer (LOF) gold snail and banan weevil did not show a significant difference between the two ingredients
