The influence of electric voltage on the germination of leguminous seeds

The aim of this paper was to examine the influence of the electrostatic field on seeds of soybean (Glycine max L), vetch (Vicia spp. L.), pea (Pisum sativum L.), grass pea (Lathyrus sativus L.) and chickpea (Cicer arietinum L.) which were selected at the Institute of Field and Vegetable Crops in Novi Sad. The DC voltage of 9V was used. The durations of seed treatment were 0 (control), 1, 2 and 3 minutes. The trial was set up as a randomized block design with four replications. 4x100 seeds of each variant and control (untreated seed) were treated. After treatment, seed quality was examined using a germination test (optimal temperature) and a cold test (low temperature). The results of the study showed that the effect of the electrostatic field on seed quality depended on the plant species, the time of seed treatment and the temperature conditions in which the seed germinated after treatment. The increase in germination energy ranged up to 18.18% in vetch, and a decrease of up to 12% was observed in chickpea. The application of the electrostatic field had a significantly greater impact on seeds that were exposed to low temperatures in the germination process after treatment. The increase in seed germination ranged up to 82.35% in chickpeas, and the decrease amounted to 92.68% in peas. In addition, the obtained results indicate that it is not possible to talk about the universal application of a certain duration of seed treatment.

Abstract Plant growth is influenced by seed quality. Seeds need to be treated to prevent pest and disease disorders or to increase seed germination. Soybean planting was carried out in this study by the treatment of varieties and seed pre-treatment application before planting. The study aimed to measure the growth and yield of soybeans by varieties and seed treatment before planting, carried out in the Village of Nggembe, District of Bolo, Bima Regency. The study used factorial randomized block design with two factors. The first factor was soybean varieties consisting of two levels, namely Devon and Dena varieties, and the second factor was the application of pre-planting seed treatments consisting of four levels namely Cruiser, Marshall, Agrisoy, and without seed treatment, each treatment was repeated three times. Observations were made on the performance of agronomic crops and soybean yields. The results showed that the treatment of soybean varieties and the application of seed treatment had a significant influence on plant height and soybean productivity, and both treatments had interactions on parameters of plant height, number of filled pods, weight of 100 seeds, and soybean productivity with the best results successively produced by a combination of Devon-Control, Devon-Marshall, Devon-Agrisoy, and Dena-Cruiser.

Abstract: The objective of this work was to evaluate the effect of different grain sizes and treatments in the physiological quality of seeds and performance of soybean cultures. The object of analysis were seeds from the cultivars Monsoy 5730 IPRO and Monsoy 5947 IPRO, sized 5.5 and 6.5 mm. The industrial seed treatment was carried out in lot equipment, with the products cyantraniliprole, thiamethoxam, metalaxyl, thiabendazole, and a combination of fludioxonil + polymer + talc. The conventional treatment was performed with the products cyantraniliprole, thiamethoxam, metalaxyl, thiabendazole, and fludioxonil. Part of the seeds was kept untreated (control). The experiment used a randomized block design, with four replications. The parameters assessed include the moisture content measurement, seed coating, germination, first germination count, field emergence, survival rate, and grain yield (right after the seed treatment and after 45 days of storage). The industrial treatment method produced a better seed coating. As for seed size, it had no effect on quality or grain yield. Last, the treated seeds presented the best results for emergence in field, while the industrial treatment achieved the highest productivity.

An important aspect in the cultivation of vegetables is the quality of the product to be marketed, free from dirt and damage and the practice of mulching could be an option, but there is scarse information. The aim of this study was to evaluate the influence of mulching on the production traits of three cultivars of Pak Choi. The experiment was set up during March to May 2013 using a split plot randomized block design, with four replications. Soil cover treatments (white agrotextile, black agrotextile, black plastic, silver plastic, tifton straw and bare soil) were arranged in the plots, and three cultivars of Pak Choi (Green Pak Choi, White Pak Choi and Chingensai Natsu Shomi) in subplots. Height and diameter of shoots, number of leaves, fresh weight of the head and petiole, base diameter, dry weight of stem, petiole, and leaf were evaluated thirty-five days after transplantation. The total dry weight and leaf area were measured, and then we estimated the yield. There was a significant effect of soil cover and cultivar. In general, the cover with synthetic materials showed higher values on production of Pak Choi. The cultivar White Pak Choi was better adapted to the growing conditions, with an average yield of 57.78 t/ha.

Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.

ABSTRACT Sweet sorghum culture is an alternative to sugar and ethanol production. With the aim of evaluating herbicide tank-mix selectivity associated or not to sweet sorghum seed treatment with naphthalic anhydride, two experiments with ESX5200 and EJX7C5110 hybrids were performed in red oxisol (clayey) field conditions, in the municipality of Campo Mourão, Paraná state. A randomized block design was used, with 4 x 2 factorial scheme, with four replications. The first factor represented three herbicide associations and a control sample without herbicide, and the second factor was constituted by the absence or presence of seed treatment with naphthalic anhydride (5.0 g kg-1). Herbicide treatments were tank-mixes of atrazine + S-metolachor (2,640 + 480 g ha 1) (pre-emergence); atrazine + S-metolachlor + isoxaflutole (2,640 + 480 + 11.25 g ha-1) (pre-emergence) and atrazine + S-metolachlor (1,500 + 384 g ha-1) (post-emergence). The following characteristics were evaluated: intoxication, plant height, stalk diameter, number of internodes per stalk and plant density, performed 60 days after emergence (DAE); stalk yield and Brix, were evaluated on day 85 DAE. Atrazine + S-metolachlor tank-mix applied in pre or post-emergence did not affect growth, development, yield and stalk quality of the ESX5200 and EJX7C5110 sweet sorghum hybrids. Sweet sorghum seed treatment with naphthalic anhydride provided partial protection against the action of atrazine + s-metolachlor + isoxaflutole tank-mixes, being more evident for the ESX5200 hybrid.

Set Up

Papaya is a popular fruit and is grown commercially in many subtropical and tropical countries. Papayas are generally grown from seeds; therefore the offsprings are not true-to-type and could come in three sexes, female, male, and hermaphrodite. Clonal propagation is required to obtain to grow true-to-type hermaphrodite papayas. In this research, we developed an in vitro protocol for shoot multiplication from lateral shoots from in vitro germinated papaya seedlings. The in vitro propagated plant materials could potentially be used as a source of papaya micro cuttings, or as scion for papaya grafting. The experiment was set up as a factorial experiment with NAA at 0, 0.1 and 0.5 mg.L-1, and BAP at 0, 0.1, 0.5, and 1.0 mg.L-1 in a completely randomized block design. BAP interacted with NAA in affecting the shoot production per explant. The optimum BAP and NAA concentration to produce lateral shoots was 0.54 mg. L-1 and 0.1 mg.L-1, respectively. Media without NAA reduced the number of lateral shoots and number of leaf per explant at any BAP concentration.Keywords: hermaphrodite, seeds, true to type, clonal propagation, micro cuttings.

Long bean production in Indonesia continues to decline every year, this is due to land conversion and the lack of application of agricultural technology. One of the efforts to increase long bean production is by multiplying quality seeds using organic materials as nutrients needed by plants. This study aims to determine the response of the growth and production of long bean seeds to the interaction of strains, varieties with a concentration of liquid organic fertilizer. The research was conducted at the Vegetable Crops Research Institute, Lembang, West Bandung Regency from July 2020 to January 2021. The research method used was an experimental method with a Randomized Block Design (RBD) with a split-plot design consisting of 2 factors: the first factor (main plot) (A) was the variety and strain with 2 levels, a1 (Tavi canton variety) and a2 (pras-1 strain).The second factor (subplot) (B) is concentration of biopras-1 with 5 levels, b1 (0 cc/l-1 water), b2 (1 cc/l-1 water), b3 (2 cc/l-1 water), b4 (3 cc/l-1 water) and b5 (4 cc/l-1 water). The effect of the treatment was analyzed by means of variance and if the f test at 5% level was significantly different, then to find out the best treatment was continued with the DMRT (Duncan Multiple Range Test) at the 5% level. The results showed that there was an interaction between varieties, lines with various concentrations of biopras-1 liquid organic fertilizer on dry seed weight per plant, dry seed weight per plot, and 1000 seeds weight. Treatment of pras-1 lines with the concentration of liquid organic fertilizer biopras-1 4 cc / l of water was able to give the best results on dry seed weight per plant (35.31 gr), dry seed weight per plot (1.298.20 gr or 2.16 Ton/ha-1) and the weight of 1000 seeds (153.10 gr).

Abstract This study aims to obtain sucker weight and appropriate seedling site as a source of sago seeds by using seedling techniques in polybags to improve seed quality on sago cultivation. The experiment used a factorial design arranged in a randomized block design with three replications. Factor A, namely sucker weight, consisted of <999 g, 1000-1499 g, 1500-1999 g and > 2000 g. Factor B is the seedling site, consisting of laying seeds in the field, greenhouse and paranet of 60%. The results of the study showed that there was no interaction between the sucker weight combined with the seedling site, but the sucker weight had a significant effect on the number of rachis and the number of primary roots per plant and the percentage of life seedlings. Higher rachis growth was 3.8 obtained from medium-sized sucker weights (1000-1499 g and 1500-1999 g) and the highest number of primary roots was 41.3. It is obtained at sucker weights of 1000-1499 g. Meanwhile, the higher percentage of seedling survival was obtained at medium to large sucker weights of 66.3-71.0%. Thus, multiplication of sago seeds using medium-sized sucker on polybag media is highly suggested.

Pakcoy is a type of mustard plant that is quite popular with the community, it is very suitable to be cultivated considering the need for vegetables is quite large. The community's need for fresh and pesticide-free vegetables is a choice now in line with the community's understanding of a healthy diet. Alternatives to fulfillment are chosen by planting with hydroponic media. Hydroponics is a substitute for soil media that can be used to grow vegetable crops. The presence of hydroponics is expected to be able to overcome the narrowing of agricultural land and reduce the use of pesticides considering that pesticides greatly affect human health and the environment. This study aims to determine the effect of nutritional doses of AB mix agrifarm and age of seedlings and their interactions on the growth and yield of pakcoy plants, this study is carried out in the experimental garden of the Faculty of Agriculture, Tabanan University which began on 9 December 2018 until 12 January 2019. The study used a Randomized Block Design (RBD) consisting of two factors. The first factor is the nutritional dose of AB mix agrifarm (N) which consists of three dose levels, namely the dose of 850 ppm, 1050 ppm and 1250 ppm. The second factor is the age of seedlings (U) which consists of two seedling age levels, namely the age of seedlings 1 week and 2 weeks. Each treatment is repeated four times. The results of the study obtained the interaction of dose agrifarm treatment with seed age showed a very significant effect (p 1 0.01) on all parameters except for the parameters of the number of leaves aged 35 days old which showed no significant effect (p 5 0.05). The economical wet weight of plant-1 and BKO of the highest yield of 1-crop yield is produced in the combination treatment of N3U, which amounted to respectively 244.09 g and 78.10g or increased respectively by 57.78% and 293.85% compared to results the lowest produced by the combination treatment of N1U1 is 154.71g and 19.83g

ABSTRACT The salinity of water and soil reduces the growth and production of crops, especially the fruit trees, such as papaya. Thus, it is necessary to obtain management alternatives for cultivation under these conditions. Therefore, the objective of this study was to evaluate the growth and phytomass of papaya cultivated under irrigation with saline water and organic fertilization. An experiment was set up using a randomized block design, with the treatments distributed in a 5 x 2 factorial scheme, consisting of five levels of salinity of irrigation water (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and two levels of organic fertilization (10 and 20 L of bovine manure per plant), with three replications, totaling thirty experimental plots. Growth variables of papaya were evaluated. Papaya plants were negatively affected by irrigation water salinity, with a greater effect on the number of leaves and on dry phytomass of leaves, with no effect of bovine manure levels.
