Soil Caco3

Little published evidence exists which relates narrow-leafed lupin growth to lime levels in soils when compared with growth on a soil with minimal or zero levels of lime. This pot experiment measured lupin growth and nodulation plus plant levels of Ca and Fe by using mixtures of a gilgaid black earth soil with varying quantities of free lime. A sand control allowed a plant growth comparison at minimal levels of lime. Iron sequestrene was added to all treatments to eliminate iron chlorosis. Plants harvested 68 days after sowing showed adequate levels of Fe. However, plant height, branch number, shoot and root dry weight and nodulation were markedly lower for plants grown on the low lime depression soil than those from the sand. Further major reductions in all aspects of growth occurred with increasing levels of the mound (high lime) soil. These effects were strongly related to soil and plant Ca levels; it is suggested that poor lupin growth on highly calcareous soils may be related to adverse direct effects of Ca.

This study was aimed to determine the effect of the increasing silica and boron concentration and their interaction on plant growth and soybean yield. This research was conducted from April-September 2017 in the integrated field of the experiment at the University Lampung. The treatments were 0 and 5 ppm Boron (B) fertilizer and Silica (Si) concentrations in 6 levels (0, 25, 50, 75, and 100 ppm). The difference between the means of B were calculated by using Orthogonal Contrast and response of Si was used Polynomial at a 0.05. The results showed that application of 5 ppm of B foliarly produced higher of soybean growth and production than without B treatment through variables of the dry weight and grain weight. Application of up to 125 ppm of Si foliarly was improved of soybean growth and production through variables of plant height, number of leaf, leaf area, dry weight and number of productive branch, number of pods, filled pod, and grain weight, but it didn’t affect the percentage of empty pods. The response of soybean growth and production to the increasing Si didn’t depend on the foliar B which was showed in all variables.

Abstrak : Pemupukan anorganik pada sistem budidaya pertanian menimbulkan beberapa masalah, antara lain biaya produksi meningkat, pendapatan petani menurun, tanah menjadi keras dan tidak subur, serta mencemari lingkungan. Karena itu, perlu ada upaya untuk menemukan sumber bahan baku pupuk yang mudah didapat, murah dn ramah lingkungan. Beberapa peneliti sebelumnya melaporkan bahwa rumput laut mengandung fitohormon dan elemen essensial yang dapat merangsang pertumbuhan dan hasil tanaman. Artikel ini melaporkan pengaruh ekstrak cair dan padat Sargassum aquifolium terhadap pertumbuhan dan hasil tanaman mentimun. Ekstrak cair dan padat alga tersebut diperoleh dengan metode Godlewska et al., 2016. Ekstrak cair (10%) disemprotkan satu kali seminggu selama pertumbuhan vegetatif. Ekstrak padat (5%) diberikan pada media tanah saat tanam. Ekstrak cair secara signifikan mempengaruhi sebagian besar parameter pertumbuhan (tinggi tanaman, jumlah cabang dan berat kering tunas) dan pertumbuhan generatif (jumlah dan berat buah per tanaman), namun ekstrak cair tersebut tidak secara signifikan mempengaruhi berat kering akar. Fenomena serupa juga ditemukan pada pengaruh ekstrak padat terhadap pertumbuhan dan hasil tanaman mentimun. Hasil penelitian ini memberikan indikasi bahwa ekstrak cair yang dilaporkan mengandung fitohormon, dan ekstrak padat yang mengandung elemen essensial dapat dikembangkan sebagai “biostimulan” dan “biofertlizer” organik yang dapat memacu pertumbuhan dan produksi tanaman.Kata kunci : ekstrak cair, ekstrak padat, Sargassum quifolium, pertumbuhan, hasil, tanaman mentimun.Abstract : Aplication of inorganic fertilizer in agriculture cultivation system causes some disadventages, such as increase cost production, reduce farmer’s income and soil fertility, and hqrm our environment. Therefore, it is needed to find out raw materials for fertilizer which easy to obtain, cheap and adaptive to our environment. Previous researchres reported that seaweed contained plant growth hormones and essential elements stimuliting growth and yield of plants. This article reports effect of liquid and solid extracts of Sargassum aquifolium on growth and yield of cucumber plants. Liquid and solid extracts were obtained according to modified Godlewska method (2016). Liquid extract (10%) was sprayed once a week during vegetative growth. Moreover, solid extract (5%) was applied in plant media. Liquid extract influenced significantly most growth parameters, such as plant height, branch number, shoot dry weight and yield parameters like fruit number and fruit weight per plant, but liquid extract did not significantly affect root dry weight. Similar phenomena was also found on the effect of solid extract on growth and yield of cucumber plants. The results suggest that liquid and solid extracts containg plant growth hormones and essential element respectively, could be developed as organic biostimulant and biofertilizer inducing growth and plant production.Keywords : liquid extract, solid extract, Sargassum quifolium, growth, yield, cucumber plants.

Background: Selenium (Se) is a crucial component of selenoaminoacids and selenoproteins. Therefore, Se-enriched agricultural products can reduce health complications induced by Se deficiency. Objective: This research was carried out to investigate the effects of Se bio-enrichment on Basil grown in calcareous and non-calcareous soil systems and also to evaluate the changes in Se concentration in the soil after harvesting. Methods: The experiments executed in two calcareous and one non-calcareous soil systems, and different Se application methods (control, soil application, seed inoculation, foliar application, and soil + foliar application) were administered. Selenobacteria, a plant growth-promoting rhizobacteria (PGPR), derived from the soil was used as a biofertilizer, compared to the other Se sources. Results: The results showed that both soil types and the methods of Se application had significant effects (P ˂ 0.01) on root and shoot dry weights and concentrations of P, K, Zn, Fe, and Se in both of the root and shoot. Shoot dry weight of plants treated with foliar Se was maximum in the calcareous soil. Compared to the control treatment, foliar application of Se increased shoot Se content in both calcareous and non-calcareous soils by 242% and 204%, respectively. Furthermore, the increase in shoot Se concentration in calcareous soil induced by Se application increased the concentration of other nutrients in the shoot and root. Plant growth parameters and concentrations of nutrients were significantly increased by using selenobacter inoculum. Conclusion: The application of Se-containing compounds can improve vegetable quality. Considering the daily requirement of the human body for minerals and nutrients, enriching basil with Se can play an important role in community health.

Effects of inoculation with arbuscular endomycorrhizal fungi (Acaulospora scrobiculata and Glomus mosseae) on acclimatization and growth of chrysanthemum (Dendrathema glandiflora Tzevelev) plants, propagated in vitro, under different conditions of fertilization (0, 20, and 40 mg·L-1 of NPK) were studied. Mycorrhizal colonization did not influence surviving percentage of chrysanthemum plantlets during the acclimatization stage; however, we could colonize the developing roots and reduce the amount of inoculum needed and beneficial effects on plant growth were obtained during early stages of colonizing. Plant growth in greenhouse was regulated by synergism between the effect of endomycorrhizal fungus type and soil fertilization with N, P, and K. Effects of A. scrobiculata were observed as an increasein number of leaves, leaf area, stem diameter, root volume and fresh and dry weight of leaves, stem and root. The G. mosseae fungus improved N, P, Mg, and Zn content in leaves; P, K, Ca, Mg, and Zinc in stem and Ca content in root. On the other hand, A. scrobiculata only increased N content in leaves, stem and roots; P content in leaves and roots, and Ca content in stem. Percentage of mycorrhizal colonization on roots was affected by adding N, P, and K to soil. The highest values were obtained with fertilization doses of 20 mg·L-1. The number of spores of mycorrhizal fungi was increased by adding fertilizer to soil (40 mg·L-1 of NPK).

N Form

The form of nitrogen (N) in fertilizer can influence plant growth, nutrient uptake, and physiological processes in the plant. However, few studies have been conducted on the effects of N form on tall bearded (TB) iris (Iris germanica L.). In this study, five NH4:NO3 ratios (0:100, 25:75, 50:50, 75:25, and 100:0) were applied to investigate the response of TB iris to different N form ratios. NH4:NO3 ratios in fertilizer did not affect the leaf, root, and rhizome dry weight, or total plant dry weight. Plant height and SPAD reading were affected by NH4:NO3 ratios in some months, but not over the whole growing season. Neither spring nor fall flowering was influenced by NH4:NO3 ratios. Across the whole growing season, leachate pH was increased by higher NH4:NO3 ratios. At the end of the growing season, concentrations of phosphorous (P), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu) in leaf; calcium (Ca), magnesium (Mg), Mn, boron (B) in root; and N, P, Mg, Fe, Mn, and Zn in rhizome tissues were affected by NH4:NO3 ratios. Greater NH4:NO3 ratios increased the uptake of Fe, Mn, and Zn. The net uptake of N was unaffected by NH4:NO3 ratios, which indicates TB iris may not have a preference for either ammonium or nitrate N.

Abstract Five plant growth regulators were applied to container-grown Photinia × fraseri as foliar sprays to determine their influences on plant size and lateral branching. Height, width, and lateral branch number were determined at three month intervals over one year. Treated plants generally were shorter than control plants in response to uniconazole, paclobutrazol, and benzylaminopurine (BA) and were taller than controls when BA was applied with gibberellins A4 + 7. Each growth regulator altered one or more growth factors dependent on the time after application. Paclobutrazol and uniconazole reduced shoot width 3 months after application (MAA) and 3 to 6 MAA, respectively compared to the control plants. Higher rates of uniconazole and paclobutrazol were responsible for shoot width reductions 12 MAA. Lateral branching was increased 3 MAA by dikegulac-sodium and paclobutrazol at the highest rates only and was reduced by uniconazole 12 MAA. Uniconazole reduced shoot dry weight 12 MAA.

SummaryEnhancement of the resistance level in plants by rhizobacteria has been proven in several pathosystems. This study investigated the ability of four rhizobacteria strains (Pseudomonas putida BTP1 and Bacillus subtilis Bs2500, Bs2504 and Bs2508) to promote the growth in three barley genotypes and protect them against Cochliobolus sativus. Our results demonstrated that all tested rhizobacteria strains had a protective effect on barley genotypes Arabi Abiad, Banteng and WI2291. However, P. putida BTP1 and B. subtilis Bs2508 strains were the most effective as they reduced disease incidence by 53 and 38% (mean effect), respectively. On the other hand, there were significant differences among the rhizobacteria-treated genotypes on plant growth parameters, such as wet weight, dry weight, plant height and number of leaves. Pseudomonas putida BTP1 strain was the most effective as it significantly increased plant growth by 15-32%. In addition, the susceptible genotypes Arabi Abiad and WI2291 were the most responsive to rhizobacteria. This means that these genotypes have a high potential for increase of their resistance against the pathogen and enhancement of plant growth after the application of rhizobacteria. Consequently, barley seed treatment with the tested rhizobacteria could be considered as an effective biocontrol method against C. sativus.

A concept of ratio of radiant to thermal energy (RRT) has been developed to deal with the interactive effect of light and temperature on plant growth and development. This study further confirms that RRT is a useful parameter for plant growth, development, and quality control. Based on greenhouse experiments conducted with 27 treatment combinations of temperature, light, and plant spacing, a model for poinsettia plant growth and development was constructed using the computer program STELLA II. Results from the model simulation with different levels of daily light integral, temperature, and plant spacing showed that the RRT significantly affects leaf unfolding rate when RRT is lower than 0.025 mol/degree-day per plant. Plant dry weight is highly correlated with RRT; it increases linearly as RRT increases.

Abstract Background Orobanche crenata is an obligate root parasite belonging to Orbanchaceae. Broomrape causes great damage to the faba bean. Several attempts were applied for controlling parasitic weeds. So, the aim of this work is to study the application of Trichoderma spp. as well as three rhizobacteria species in comparison to herbicidal effect of Glyphosate (Glialka 48% WSC) for controlling broomrape infesting faba bean (Vicia faba). Materials and methods Three pot experiments were carried out in the greenhouse of the National Research Centre, Dokki, Giza, Egypt during two successive winter seasons. Trichoderma inocula were adjusted to 3.6 × 108 propagules/ml and the bacterium inocula were adjusted at 107–109 colony-forming unit (CFU)/ml. All treatments were applied, before 1 week of sowing, at rate of 50 ml per pot in experiments I and II, while 100 ml per pot in experiment III. Results Trichoderma spp. (T. harzianum, T. viride and T. vierns) as well as three rhizobacteria species (Pseudomonas fluorescens, Bacillus subtilis and Bacillus pumilus) enhanced the growth parameters in faba bean plants, i.e. shoot length, shoot fresh weight, shoot dry weight and leaf number in the first experiment when applied without O. crenata infection. In the second experiment, all bio-control could protect plants against O. crenata infection, where it had better juvenile number reduction, than glyphosate after 2 months of application. Both B. subtilis and B. pumilus had the highest reduction to juvenile fresh weight, while their effect was equal to herbicide for juvenile dry weight, respectively. The bio-control agents had high effects until the 4th month, but it was less than that of the herbicide. In experiment III, the bio-control agents could highly reduce the juvenile parameters after 2 months, as well as juvenile fresh weight and juvenile dry weight after 4 months, than the herbicide, respectively. The bio-control agents were effective until 6 months, but less than the herbicide effect. All bio-control treatments highly increased the plant growth parameters, than the herbicide. Conclusion The application of Trichoderma spp. as well as rhizobacteria species could play an important role in controlling broomrape in faba bean as a natural bioherbicide.
