This study assessed the effect of petrol and spent lubricating oil on the major growth traits (such as root length, stem length, leaf area, and biomass), and the changes in epidermal layer of leaf and its mitotic index in Guinea Corn (<em>Sorghum bicolor</em> L.) exposed to 0% (control), 5%, 10%, 15% and 20% concentrations of petrol and spent lubricating oil. Each concentration was mixed with 3 kg of soil in a plastic pot and each treatment was carried out in three replicates. Forty days after planting, the leaf areas of guinea corn plant were 95.83 cm2, 89.67 cm2, 89.47 cm2, and 77.80 cm2 in control, 5%, 10%, 15%, and 20% respectively of petrol pollutant. The means of stem length were 32.50±0.5 cm, 22.60±0.65 cm, 21.27±0.75 cm, 20.83±0.28 cm and 20.33±0.28 cm in control, 5%, 10%, 15% and 20% respectively. Both leaf area and stem length of treated seedlings reduced with increased concentration of the pollutants. Additionally, reduction in the dry weight of the seedlings increased with increasing concentration of both petrol and spent oil. The micrograph of the internal anatomy of the upper epidermal layers of the leaf revealed broken and scattered epidermal cells and smaller sizes of the stomata, and were increased with the increasing concentration of the treatment. Statistical analysis of the treatment shows that there was a significant reduction (P&lt;0.05) in the stem length and leaf area of the seedlings. This study revealed that petroleum pollutant adversely affected germination, growth and development of guinea corn but petroleum products like spent oil can provide nutrition necessary for growth and yield of plant at low concentration.

Suminarti et al, 2018. Effect of Source and Dosage of Organic Materials on Changes in Soil Chemical Properties, Growth and Yield of Sorghum Plants (Sorghum bicolor L.Moench) var. KD4 in Dry Land Jatikerto, Malang. JLSO 7(2): Agricultural extensification is the right step to anticipate conditions of food insecurity. This refers to two reasons, namely (1) proliferation of land conversion activities, and (2) sorghum is a carbohydrate-producing plant that is quite tolerant when planted on dry land. The objective of this study was to obtain information about the sources and doses of organic matter that are appropriate to changes in soil chemical properties, growth and yield of sorghum plants, and has been carried out in the dry land of Jatikerto, Malang. A split plot designs with three replications were used in this study, sources of organic material (blothong, UB compost and cow dung) as the main plot, and doses of organic matter (125%, 100% and 75%) as a subplot. Soil analysis was carried out 3 times, i.e. before planting, after application of organic matter and at harvest. The agronomic observations were carried out destructively at 80 days after planting (DAP) including the components of growth (root dry weight, leaf area, and total dry weight of the plant) and harvest at the age of 90 DAP.F test at 5% level was used to test the effect of treatment, while the difference between treatments was based on LSD level of 5%.The results showed that there was a significant interaction between the source and dosage of organic matter on the leaf area and total dry weight, the highest yield was obtained in blothong at various doses. Higher yields of seeds per hectare were also found in blotong: 1.76 tons ha-1, and 1.73 tons ha-1 on 125% doses of organic matter. Blotong application is able to provide elements of N, P and K soil respectively 18.3%, 85.68% and 8.42% for plant.

The aim of this study was to evaluate the salt tolerance of forage sorghum genotypes by analysis of growth variables correlated with the levels of Na+ and Cl- accumulated in the leaves. The research was carried out in a greenhouse belonging to the Brazilian Agricultural Research Corporation (EMBRAPA) – Semiarid, in Petrolina, Pernambuco state, Brazil. The treatments were arranged in a randomized block design with factorial arrangement 10x6 with ten genotypes (‘F305’, ‘BRS 655’, ‘BRS 610’, ‘Volumax’, ‘1,015,045’, ‘1,016,005’, ‘1,016,009’, ‘1,016,013’, ‘1,016,015’ and ‘1,016. 031’), salt solutions with six levels of electrical conductivity (0, 2.5, 5.0, 7.5, 10 and 12.5 dS m-1) and three replications. The variables evaluated were dry mass and water content of the shoots and roots, plant height, stern diameter, leaf area and foliar concentration of Na+ and Cl-. It was found that the growth of forage sorghum genotypes is similarly affected due to the increase of Na+ and Cl- foliar contents. The growth of forage sorghum is reduced by 50% when the plants are submitted to the application of saline solution with electrical conductivity of 8 dS m-1. Keywords: leaf area, salt stress, dry matter, Sorghum bicolor (L.)

E. deCRESCIMENTO E TEORES FOLIARES DE Na+ E Cl- EM GENÓTIPOS DE SORGO FORRAGEIRO IRRIGADOS COM ÁGUAS SALINIZADAS   2 RESUMO A eficiência das plantas em desenvolver mecanismos específicos para sobreviver ao estresse salino pode variar significativamente entre genótipos, implicando em respostas diferenciadas no seu crescimento e rendimento. O objetivo do presente estudo foi avaliar o crescimento e teores foliares de Na+ e Cl- em dez genótipos de sorgo forrageiro submetidos a irrigações com águas salinizadas. O experimento foi conduzido em casa de vegetação localizada na sede da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) – Semiárido, em Petrolina – PE. Utilizou-se o delineamento experimental em blocos casualizados dispostos em esquema fatorial 10x6, considerando dez genótipos (‘F305’, ‘BRS 655’, ‘BRS 610’, ‘Volumax’, ‘1.015.045’, ‘1.016.005’, ‘1.016.009’, ‘1.016.013’, ‘1.016.015’ e ‘1.016.031’), soluções salinas com seis valores de condutividade elétrica (0; 2,5; 5,0; 7,5; 10 e 12,5 dS m-1) e três repetições.  As variáveis avaliadas foram massa seca e conteúdo de água da parte aérea e raízes, altura da planta, diâmetro do colmo, área foliar e teores foliares de Na+ e Cl-. Verificou-se que o crescimento dos genótipos de sorgo forrageiro foi afetado  similarmente com o aumento da salinidade devido à elevação das concentrações de Na+ e Cl- nas folhas. O crescimento do sorgo forrageiro é reduzido em 50% quando as plantas são submetidas à aplicação de solução salina com condutividade elétrica de 8 dS m-1. Palavras-chave: área foliar, salinidade, massa seca, Sorghum bicolor (L.)

The effects of different nitrogen doses on dry weight yield, stevioside and rebaudioside A contents, and yields were evaluated in stevia (Stevia rebaudiana Bertoni). This study was carried out at the Instituto Federal Catarinense, Rio do Sul (SC), Brazil, under decreasing photoperiods. A randomized complete block design with four blocks and five treatments (0, 65, 135, 200 and 270 kg ha-1 N) was used. Variables related to dry weight yield (total dry weight, leaf dry weight, stem dry weight, number of secondary branches and tertiary branches, and main stem length), growth rates (total leaf area, leaf area index, specific leaf area, leaf area ratio, leaf weight ratio), and stevioside and rebaudioside A contents and yields were evaluated. The doses of nitrogen fertilization did not affect the variables related to dry weight yield, stevioside and rebaudioside A contents and yields, or rebaudioside A:stevioside ratio in stevia genotype 8 (G8), grown under decreasing photoperiods.

<h1>The experiment was aimed to know the effect of seed biomatriconditioning with rhizobacteria to improve growth and yield of sorghum (Sorghum bicolor L.). The experiment was conducted in the Field of Animal Husbandry Agriculture Faculty, Haluoleo University from August up to November 2010. The experiment was arranged based on randomized completely design (CRD) which consisted of 5 seed biomatriconditioning with rhizobacteria treatments, namely: without seed biomatriconditioning (M0), seed biomatriconditioning with Bacillus sp. CKD061 + rice hulls charcoal (M1), seed biomatriconditioning with Bacillus sp. CKD061 + red brick powder (M2), seed biomatriconditioning with Pseudomonas fluorescens PG01 + rice hulls charcoal (M3), and seed biomatriconditioning with Pseudomonas fluorescens PG01 + red brick powder (M4). Every treatment was replicated 3 times, therefore, overall there were 15 experimental units. Data obtained were analized using analysis of variance and followed with Duncan’s Multiple Range Test. The result showed that seed treatment with biomatriconditioning using rhizobacteria gave significant effect in improving growth and yield of sorghum. Seed biomatriconditioning with sp. Bacillus CKD061 + red brick powder was the most effective treatment in increasing plant height, leaf area, dry weight of plant bomass, grain weight, and 1000 seed weight of sorghum.</h1>

SummaryEight amounts of nitrogen ranging from 0 to 210 kg N/ha were applied to two tall and one semi-dwarf variety of winter wheat in the spring of 1975 and 1976. The tall varieties were Cappelle-Desprez and Maris Huntsman; the semi-dwarf variety was Maris Fundin in 1975 and Hobbit in 1976. Interactions between varieties and nitrogen were few and small compared with the main effects. All varieties produced their maximum grain yields with 180 kg N/ha. The yield of the semi-dwarf varieties, but not the others, decreased slightly with more nitrogen.Cappelle-Desprez yielded less grain than the other varieties in both years. In 1975 the yields of Maris Fundin and Maris Huntsman were similar and in 1976 Hobbit yielded more than Maris Huntsman. The varieties had similar numbers of ears at maturity and similar patterns of tillering. The semi-dwarf varieties had most grains per spikelet, and hence grains per ear, and Cappelle-Desprez had least. The semi-dwarf varieties had the smallest grains. The semi-dwarf varieties had less straw than the other varieties and hence the largest ratios of grain to total above-ground dry weight. The decrease in dry weight of stem and leaves between anthesis and maturity was similar for all varieties. In 1975 the efficiency of the top two leaves plus top internode in producing grain was the same for all varieties, but in 1976 Hobbit was more efficient than the other two. There were some small differences between varieties in nutrient uptake that were not related to differences in growth. Maris Fundin tended to have a greater phosphorus and potassium content than the tall varieties. Hobbit contained slightly less nitrogen than the tall varieties at maturity, and had a smaller concentration of nitrogen in the grain.Applying 210 kg N/ha doubled grain yield in 1975. Applying nitrogen resulted in a largeincrease in number of ears and a small increase in number of grains per ear due to the development of more fertile spikelets per ear. Nitrogen decreased dry weight per grain, especially of the semi-dwarf varieties. With extra nitrogen, straw dry weight at maturity, shoot dry weight atanthesis and leaf area were all increased relatively more than grain yield, and stems lost moredry weight between anthesis and maturity than without nitrogen. The year 1976 was exceptionallydry and nitrogen had only small effects in that it affected neither straw dry weight nor numberof ears but slightly increased grain yield by increasing the number of spikelets and number of grains per spikelet. It also increased leaf area proportionately to grain yield. In 1975 nitrogen increased evaporation of water from the crop before anthesis but decreased it after anthesis, even though it continued to increase the extraction of water from below 90 cm.

Aged Seeds

Aged seeds exhibit compromised vigour in terms of germination, seedling emergence and growth, but this can to some extent be alleviated by invigoration treatments before sowing. This study aimed to investigate ageing rates and patterns in cabbage (Brassica oleraceae) and lettuce (Lactuca sativa) seeds and whether the beneficial effects of invigorating aged seeds with exogenous antioxidants translate to enhanced seedling performance. Seeds were artificially aged to 25% viability before soaking in 0.4 mM glycerol, 0.6 mM GSH and 0.2 mM trolox for cabbage, and 0.6 mM glycerol, GSH and trolox for lettuce; deionised water served as a control. After 14 days of sowing, seedling emergence percentage, mean emergence time, mean daily emergence, and time taken to 25% emergence were computed. Seedling vigour index, root and shoot dry weight, root:shoot ratio, leaf area, leaf area ratio, and leaf chlorophyll content were assessed 6 weeks after sowing. Furthermore, the photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (E), and chlorophyll fluorescence were measured 6 weeks after sowing. Notably, ageing resulted in the loss of seed vigour and viability at higher rates in lettuce than cabbage. Seed pretreatment with glycerol promoted seedling growth in both species and shoot dry weight in lettuce, while glycerol and GSH enhanced Pn, Gs and E in lettuce. Trolox also enhanced Pn and E in lettuce. The beneficial effects of the antioxidant treatments are thought to be associated with the protection of photosystems from oxidative stress and/or stimulation of enzymes involved in photosynthesis, possibly through an enhanced antioxidant defence system during the early development stages when seedlings are particularly vulnerable to stress.

Field trial was carried out during the 2019 rainy season (June to October) at the Dryland Teaching and Research Farm of the Faculty of Agriculture, Usmanu Danfodiyo University, Sokoto to determine the growth and yield of sorghum varieties in the study area. The treatments consisted of five (5) sorghum varieties (Samsorg 45, Samsorg 46, Janjari, Yartawa and Jardawa), the treatments were laid out in a Randomized Complete Block Design (RCBD) replicated three (3) times. Data were collected on the growth and yield of the crop. Janjari and Jardawa varieties were higher in plant height. Jardawa and Yartawa varieties were higher in number of leaves. Janjari and Yartawa varieties were higher in total dry weight. Janjari, Jardawa and Yartawa varieties were higher in harvest index. Yartawa variety was higher in leaf area, leaf area index and 1000-grain weight. Jardawa variety was higher in panicle length. Janjari variety was early in number of days to heading, flowering, and maturity and was higher in dry stalk weight. The grain yield (249 – 1506kg ha-1 ) was higher in Janjari and Yartawa varieties (1268 – 1506 kg ha-1). Based on the findings of this research, it could be concluded that Janjari and Yartawa varieties performed better than other varieties in the study area.
