Effects of Biochar Application in a Sorghum Crop under Greenhouse Conditions: Growth Parameters and Physicochemical Fertility

Application of biochar from vine shoots (Vitis vinifera L.) as an organic amendment in the soil is an alternative agricultural management of interest. The behavior of this type of amendment in the soil requires more information to adjust the pyrolysis conditions in order to obtain a high-quality biochar. The aim of this work is determining the influence of the application of this type of biochar on the soil-plant system. For this purpose, an agronomic test was performed in greenhouse pots. A randomized tri-factorial block design was adopted with the following factors: final pyrolysis temperature (400 and 600 °C), application rate (0 wt. % as a control, 1.5 and 3 wt. %) and texture of the growing media (sandy-loam and clay-loam origin). The selected crop was sorghum (Sorghum bicolor L. Moench), the development and production of which was evaluated during two complete growing cycles under greenhouse conditions. Application of biochar produced at 400 °C significantly increased plants roots dry weight in the sandy-loam growing substrate (52% compared to the control). Grain production was also significantly affected by biochar application, showing better results after addition of biochar produced at 400 °C. Water holding capacity and K, Ca, and Mg contents were enhanced by biochar addition, with evident effects of the application ratios for some of these variables. The effect on the pH of substrates in the sandy-loam texture was weak; however, a significant decrease was observed after the addition of biochar produced at 600 °C.

Hot pepper is an important vegetable and spice crop in Ethiopia. However, the productivity of hot pepper is limited by poor soil fertility and lack of proper soil and water conservation measures under irrigated condition. Therefore, hot pepper crop response to nitrogen (N) fertilizer and mulching experiment was conducted at Alage ATVET College. The treatments consisted of three mulch types (no mulch, transparent plastic mulch, and dry banana leaves mulch) and four levels of N (0, 50, 100 and 150 kg N ha-1) factorial arranged in a randomized complete block design with four replications. A hot pepper cultivar commonly known as “MarekoFana” was used for the study. Days to 50% flowering, 50% fruit set, maturity and harvest were significantly prolonged in response to increasing N application. The delays were about 7, 19, 23 and 12 days at the N levels of 50, 100 and 150 kg N ha-1respectively compared to the control. The analysis of variance revealed that plant height, number of branches per plant, number of pods per plant, dry weight of seeds per pod, total weight of dried pods per plant, weight of individual dry pods and width were significantly (P = .001) increased by the main effect of mulching. Generally, the results revealed that nitrogen application significantly (P = .001) influenced all growth parameters, pod yield, and yield components of the crop. Nitrogen application at 100 kg ha-1 resulted in the highest total dried pod yield (4.5 tha-1), marketable yield (3.76 t ha- 1), pod length (13.3 cm), pod width (3.2 cm), mean dry weight of pod (3.85 g), and seed number per pod (108.4). The interaction of N and mulching also significantly (P = .05) affected marketable and total pod yields. In conclusion, based on agronomic performance and partial budget analyses results we recommend a combined application of dry banana leaves mulch and 100 kg N ha-1 for economically feasible and sustainable hot pepper production in Alage areas of Central Rift Valley of Ethiopia.

Parameter Values

There is limited information on optimal substrate EC level for begonia species (noncultivated hybrids). The objective of this study was to evaluate the response of six species to different substrate EC in a greenhouse. Begonia albopicta, B. cucullata var. cucullata, B. echinosepala var. elongatifolia, B. holtonis, B. fuchsioides (red) and B. fuchsioides (pink) plants were propagated by stem cuttings, and transplanted into plastic pots using a soilless mix. Five concentrations (20, 80, 200, 400, and 600 mg·L-1 N) of 17–5–17 fertilizer were applied as irrigation water to derive the five substrate EC levels. This experiment was a factorial randomized complete-block design. Substrate EC was measured weekly using the PourThru method and averaged for each treatment of each species. Inflorescence number, the longest stem length, SPAD readings, leaf area, and dry weight of each plant were measured as growth parameters. There were significant responses to substrate EC level and species on begonia growth parameters. The highest growth parameters of B. albopicta and B. cucullata were obtained at EC 5.7 and 6.6 mS·cm-1, respectively. The maximum growth of B. echinosepala and B. holtonis was observed at 2.6 and 3.0 mS·cm-1, respectively. B. fuchsioides, grown at 1.2 mS·cm-1, had the best growth parameter values. As EC level increased, SPAD value for B. fuchsioides (pink) and B. holtonis also increased. The highest SPAD reading was observed at EC 3.7 mS·cm-1 for B. albopicta, EC 6.6 mS·cm-1 for B. cucullata, EC 2.6 mS·cm-1 for B. echinosepala, and EC 4.1 mS·cm-1 for B. fuchsioides (red). Plant mortality of several begonia species was observed when grown at EC value above 6.4 or below 4.4 mS·cm-1.

Two experiments were conducted in the Savelugu-Nanton Municipality of the Northern Region of Ghana in 2012 and 2013 to assess the effect of N fertilizer on growth, N remobilization and grain yield of three local varieties of soybean (Glycine max [L] Merill). The experiments were a 3 x 4 factorial laid in Randomized Complete Block Design (RCBD) with four replications. Factor A was soybean varieties (Jenguma, Quarshie, Ahotor); Factor B was 0, 15, 30 and 45 kg N ha-1. The experimental fields were planted manually on the flat by drilling and later thinned to 2 plants hill-1 at 0.50 m × 0.10 m with a population of about 400 000 plants ha-1. Growth and yield parameters measured were plant height, nodule number plant-1, nodule dry weight plant-1, percent nodule effectiveness, number of pods plant-1, number of seeds pod-1, 100 seed weight, harvest index and grain yield. The results showed that the control recorded lower figures in all growth parameters. Nitrogen remobilization was also observed in all plots, which indicate that soybean needs greater levels of N during grain filling. Again, N remobilization and soybean yield were highest in the 45 kg N ha-1 treatment compared to the other treatments. However, considering the overall yields, farmers in the study area should be advised to adopt starter N fertilization of soybean for higher yields as the soils are highly degraded in soil fertility.

Waterlogging is one the major abiotic stresses that affects growth and yield of blackgram. A field experiment was carried out at the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, 1706 during kharif II season to evaluate 26 blackgram genotypes for understanding the flood tolerance in respect of yield and yield contributing characters. The experiment was laid out with a randomized complete block design with three replications. Water logging depth was 3-5 cm, created by irrigation from tap water and imposed at 29 days after emergence of seedlings which was maintained for 8 days. Multivariate analysis was performed involving eight qualitative plant characters. A wide range of variation was found for all the qualitative plant characters like plant height, plant dry weight, branches per plant, pods per plant, pod length, seeds per pod, 1000-seed weight and yield per plant. Flooding reduced all the growth parameters of blackgram but degree of reduction varied greatly over the blackgram genotypes. Considering yield performance, the genotypes BU Acc 25 showed the highest yield per plant (9.03 g) followed by the BU Acc 17 (6.47 g) and BU Acc 24 (6.17) under flooding . The yield reduction percent of the same genotypes were minimum (43.86, 60.82 and 65.96, respectively) compared to control which is very important for selection of those genotypes as a flooding tolerant.

Morpho-anatomy and physiology of red galangal (Alpinia purpurata) and white galangal (Alpinia galanga) under some salinity stress levels. Biodiversitas 19: 809-815. Soil salinity is one of the most urgent issues in agriculture as it can reduce plant growth and productivity. Efforts on development of galangal plant on saline soils are still encountering some obstacles such as lack of information on the galangal types that are tolerant to saline condition. The purpose of this study was to determine morpho-anatomical and physiological responses of red galangal (Alpinia purpurata (Vieill.) K. Schum.) and white galangal (Alpinia galanga (L.) Willd.) to salinity stress treatments. This research used a Randomized Block Design (RBD) assigned in a factorial treatment design of two factors, i.e., (i) species of galangal consisting of two levels i.e., red galangal and white galangal, (ii) NaCl concentration consisting of five levels, i.e., 0‰, 3‰, 6‰, 9‰ and 12‰. Each treatment was three replicates. Observation was done on the growth parameters when the plants showed wilting symptoms. The observed data were subjected to Analysis of Variance (ANOVA), followed by a post hoc Duncan Multiple Range Test (DMRT) at α 5% when the treatment effect was significant. The results showed that salinity stress treatment significantly reduced the plant height increase, leaf area, dry weight, stomata density, chlorophyll content and increased thickness of root epidermis, and proline content in both species of galangal. Red galangal was more tolerant than white galangal.
