The effects of the carbonization product of separated communal waste as an additive to the soil was studied on the germination, quantitative growth and yield parameters of maize (Zea mays L.), bean (Phaseolus vulgaris L.) and tomato (Solanum lycopersicum L.). The product was tested on three soil types with different humus content and mineral composition in doses of 1, 10 and 20 g of additive per kg soil, with application before seeding or after plant emergence, under greenhouse and field conditions. It was found that plants utilized the nutrient content from the carbonization products in both methods of application and that the stimulatory effect on the germination, fresh and dry mass and yield parameters of the treated plants was dependent on the plant species, soil type, dose and method of application. A significant effect of the additive was found on the germination of bean, which increased by 8-22% over the control. Fresh and dry mass increased by 18-62% in maize and by 2-30% in bean when the additive was applied under greenhouse conditions. In the field the additive was found to have a positive effect on the average mass of tomato fruits and maize cobs, and on the yield per plant.

Abstract Seaweed extracts are employed as biostimulants due to their beneficial effects on crop growth and yield. Ascophyllum nodosum seaweed extract aid to improve seedling growth and development, and decrease seedlings production costs; however, the correct concentration must be used in order to maximize the biostimulant effects. Consequently, this study aimed to analyze the effects of different concentrations of a seaweed-based (Ascophyllum nodosum) biostimulant on ornamental sunflower seed germination and seedling growth. Seeds of ornamental sunflower cv. “Sol Pleno” were sown in polyethylene trays containing commercial substrate. The treatments consisted of dairy spraying 60 mL of the solutions 0 (control), 5, 10 or 15 mL L-1 biostimulant on substrate. The experimental design was completely randomized with 4 treatments (concentrations of biostimulant) and 4 replicates (10 seeds replicate-1). The evaluated variables were percentage, index and time averages of germination, seedling height, fresh and dry mass of shoot and roots, and root system morphology (WinRhizo). The increase of the biostimulant concentration enhances seed germination and seedlings development. The concentration 15 mL L-1 biostimulant showed the best results for percentage and index of germination and the lowest mean germination time and increase plant height and fresh and dry mass of shoots in relation to the control treatment. Accordingly, 15 mL L-1 biostimulant (Ascophyllum nodosum) is recommended for ornamental sunflower “Sol Pleno” seed germination and seedlings growth.

Lettuce plants, cv. Vera, were grown under five salinity levels in a hydroponical experimental set-up using a 0.15 m deep sand growing bed. A standard nutrient solution was used, with the following composition, in mmol L-1: 16.9 NO3-; 2.0 H2PO4-; 1.0 SO4- 4.0 Ca++; 10.9 K+ e 1.0 Mg++, and, in mg L-1, 0.42 Mn; 0.26 Zn; 0,05 Cu; 0,50 B; 0,04 Mo, and 4.82 chelated Fe. The five salinity levels compared as treatments were obtained by varying the concentration of the standard nutrient solution, reaching average electrical conductivities (EC) of 0.80; 1.93; 2.81; 3.73 and 4.72 dS m-1, for T1, T2, T3, T4 and T5, respectively. The nutrient solution at each salinity level was supplied from a reservoir by means of a flooded-type electrical pump, for 15 minutes, at intervals of 90 minutes during the day and 420 minutes during the night. A completely randomised experimental design was used with four replications and 20 plants per plot. Four plants of each plot were harvested at 32 days after planting, to determine shoot and root dry mass, shoot fresh weight, leaf area and number of leaves per plant. Number of leaves was 18 per plant and was not affected by treatments. Dry mass of leaves increased 24,4% from T1 to T3. No relationships were found on data from stem and root dry mass. A positive effect of EC was recorded on shoot fresh mass, which increased 28.5% from T1 to T2, and decreased 16.5% from T2 to T5. Maximum LAI estimated value was 4.3 m² m-2 for an EC of 2.6 dS m-1. Salinity levels above 2.0 and 2.6 dS m-1 reduce fresh yield and plant growth, respectively.

The role of preparations supporting plant growth is mainly to reduce the harmful effects of various stress factors on plants and to ensure high yields of good quality. This experiment compared the effect of the mineral stimulator Tytanit® and the biological preparation Effective Microorganisms (EM) on the physiological and biochemical activity, as well as the yield of the common bean (Phaseolus vulgaris L.). The photosynthetic pigments, free proline and malondialdehyde were assayed and compared at three phenological phases of the bean: 15 BBCH, 24 BBCH, 65 BBCH. The yield parameters included the average number of pods per plant, as well as their fresh and dry mass. Additionally, the nutrient content in the pods was determined according to the atomic absorption spectrometry method. The study revealed a positive effect of both preparations on increasing the content of chlorophyll a, b, and the carotenoids in the bean leaves. Plants treated with Tytanit® were characterised by the highest content of malondialdehyde and proline, while EM maintained the aldehyde content on a similar level compared to the untreated plants and significantly reduced the proline content. Both preparations significantly decreased the Mn, Mg, P, and Ca content in the pods and did not have a substantial impact on the yield.

Soil acidity is a major factor limiting green beans (Phaseolus vulgaris L.) production in the Cameroon western Highland. A field experiment (split-plot layout) was conducted with seven dolomite treatments (tons ha-1): control or T0 (0), T1 (0.5), T2 (1), T3 (1.5), T4 (2), T5 (2.5) and T6 (3). Soil physico-chemical properties were determined meanwhile growth and yield parameters were collected weekly for a month and analyzed statistically. Results revealed that control soils were texturally silty sandy. The exchangeable bases (except Na), cation exchange capacity (CEC), base saturation and available phosphorus were very high. They acidity was moderate to high (5.2 to 5.6) while organic matter was very high (% dry mass) and of moderate to good quality (11<C/N ratio<13). Crop variety showed a highly significant difference (P<0.001) for all growth and yield parameters, with Cogito producing the longest (13.88 cm), most numerous (40.94 pods per plant) and highest (16.96 tons ha-1) extrafine pods. Dolomite doses revealed no significant effects (P>0.05) on crop parameters, although highest yield (13.61 tons ha-1) of extrafine pods came from 2 tons ha-1. The dolomite dose versus variety interaction showed no significant difference (P>0.05). Farmers ought to improve soils with compost and cover crops to check nutrient leaching and erosion.

Balanced fertilization is a pre-requisite for better rice production and it is necessary to determine optimum combination of nutrient elements for application. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Boro season to investigate the effects of reduced rates of phosphorus (P) and sulphur (S) on the growth, yield, nutrient content and uptake by rice. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and eight treatments viz. T1: Control, T2: Recommended Fertilizer Dose (RFD), T3: RFD -20% P, T4: RFD-40% P, T5: RFD-20% S, T6: RFD-40% S, T7: RFD-20% PS and T8: RFD-40% PS. The recommended fertilizer doses were 125 kg N ha-1, 25 kg P ha-1, 70 kg K ha-1, 15 kg S ha-1 and 3 kg Zn ha-1 supplied from urea, TSP, MoP, gypsum and zinc sulphate, respectively. There was significant effect of reduced rates of P and S fertilizers on rice yield compared to control. The highest grain yield of 5.10 t ha-1 and straw yield of 7.02 t ha-1 were recorded from treatment T2 (RFD) that produced the maximum values of all the yield components and the highest content and uptake of nutrients. The performance of T2 and T3 (RFD - 20% P) was statistically similar in producing yield parameters, yields, nutrient contents and uptake by rice. Again, 20% reduced rate of S (T5) or of P and S (T7) caused significant yield reduction, poor yield parameters and less nutrient uptake compared to T2. Thus, the recommended fertilizer dose and the treatments where 20% P was reduced from the RFD are equally efficient in increasing yield as well as enhancing nutritional quality of rice. This reduction of chemical fertilizer could help lessen the cost of rice production with decreasing environmental risk. Asian J. Med. Biol. Res. March 2021, 7(1): 40-47

<p>Fenugreek (<em>Trigonella foenum-graecum </em>L.) is an annual herb used as organic (green) manure and has medicinal applications. Organic fertilizers are used in sustainable agriculture of vegetables. Sources of organic manure and their effects on growth and yield characteristics of plants need to be determined. Effects of vermicompost and vermiwash were determined on qualitative and quantitative factors of chemical content, development and yield of fenugreek (<em>Trigonella foenum-gaecum </em>L.) from May to July 2012 at Agriculture College of University Guilan. A completely randomized block design with 3 replications was used. Treatments included 7 t/ha of cow manure, vermicompost, vermiwash (obtained from 7 t/ha vermicompost); 7 t/ha of leachate vermicompost + vermiwash and a control (no fertilization). Use of organic fertilizers beneficially affected plant height, pod length, pod fresh and dry mass, 1000-seed mass, plant fresh and dry mass, internode length and percents of leaves protein and nitrogen. Use of organic fertilizers may increase yield and yield components of fenugreek and its yield efficiency.</p>

<p>Salinity is one of the main abiotic stress factors which limit the growth and productivity of plants, however, the nutritional status of plants is the first brick in the resistance wall against stresses. Therefore, a factorial experiment was undertaken to investigate effects of soil applied humic acid (0, 7, 14, 21 l.ha<sup>-1</sup>) and boron foliar spraying (0, 50, 100 ppm) and their interaction on growth and yield of melon plant under saline conditions. The results suggested that the treatments soil application of humic acid and the boron spraying successfully mitigated the deleterious effects of salt stress and influenced growth and yield of melon plant. Humic acid at 21 l.ha<sup>-1</sup> or boron spray at 50 ppm exhibited an improvement in growth and yield of melon, in terms of plant length, plant fresh and dry mass, chlorophyll (SPAD), fruit mass, total yield, and also leaf nutrient content (N and K) and total soluble solids (TSS) of fruits, while reduced the sodium content of leaves. The combined treatment of humic acid at 21 l.ha<sup>-1</sup> and boron spraying at 50 ppm was found to be more effective for the melon plant to improving growth performance and the crop yield by 21 % as compared with the control group under saline conditions.</p>

The study investigated effect of vermicompost enriched with fish silage on the growth, yield and biochemical constituents of cowpea. The experiment was laid out in a randomised complete block design (RCBD) in three replicates with plot size of 2.0×2.0 m each. The treatments were chemical fertiliser (CF) (100 kg urea + 300 kg single super phosphate ha-1), fish silage enriched vermicompost (VCS) (3.33 t of enriched vermicompost and 300 kg single super phosphate ha-1) and vermicompost (VC) (4.5 t vermicompost + 300 kg single super phosphate ha-1). Data on growth and yield parameters of cowpea were analysed. Chlorophyll and carotenoid content of the leaves were also estimated. Results showed that cowpea performed best with the enriched vermicompost in terms of average yield of fruits per plant (209.27 g), plant height (114.2 cm), total number of branches per plant (13.4), weight per fruit (4.41 g) and number of seeds per fruit (10.5). Cowpea plants given inorganic fertiliser had a better biochemical profile with higher total chlorophyll (37.52 mg g-1) and carotenoid (1.497 mg g-1) content than the organic manure treated plants. Results revealed that enriching vermicompost with fish silage is a potential option for improving the nutrient content of vermicompost, resulting in higher crop production by converting fish waste into a useful byproduct.
