ABSTRACTThis study aimed to evaluate the chemical attributes of an Inceptisol cultivated with castor bean (Ricinus communis L.), variety ‘BRS Energia’, fertilized with sewage sludge compost and calcium (Ca) and magnesium (Mg) silicate. The experiment was conducted at the ICA/UFMG, in a randomized block design, using a 2 x 4 factorial scheme with three replicates, and the treatments consisted of two doses of Ca-Mg silicate (0 and 1 t ha-1) and four doses of sewage sludge compost (0, 23.81, 47.62 and 71.43 t ha-1, on dry basis). Soil organic matter (OM), pH, sum of bases (SB), effective cation exchange capacity (CEC(t)), total cation exchange capacity (CEC(T)), base saturation (V%) and potential acidity (H + Al) were evaluated. There were no significant interactions between doses of sewage sludge compost and doses of Ca-Mg silicate on soil attributes, and no effect of silicate fertilization on these attributes. However, fertilization with sewage sludge compost promoted reduction in pH and increase in H + Al, OM and CEC. The dose of 71.43 t ha-1 of sewage sludge compost promoted the best soil chemical conditions.

ABSTRACTThis study aimed to evaluate the residual effect of sewage sludge fertilization on yield and nutrition of sunflower in its second cycle. The experiment was carried out from April to August 2012. The treatments consisted of four doses of sewage sludge (0, 10, 20 and 30 t ha-1, dry basis) applied in the first cycle of sunflower, distributed in a randomized block design, with six replicates. Sunflower stem diameter, plant height, capitulum diameter and yield increased with the increment in sewage sludge doses, with maximum values observed with the dose of 30 t ha-1. The contents of calcium and magnesium in the soil, pH, sum of bases, effective and potential cation exchange capacity and base saturation increased, while potential acidity and the contents of manganese and iron in the leaves decreased, with the increment in the residual doses of sewage sludge. There was a reduction in yield and growth characteristics of sunflower in the second cycle; thus, additional fertilization with sewage sludge is recommended in each new cycle.

Abstract. Tsegay BA, Gebreegziabher BG. 2019. Effects of terrains’ soil and altitude on performance of Abyssinian pea (Pisum sativum var. abyssinicum A.Braun) landraces of Ethiopia. Biodiversitas 20: 3467-3477. Pea production in Ethiopia is mainly located in the highlands. Field-based agronomic performance evaluation of Abyssinian pea landraces at different altitudes and soil types are rarely explored. This study was conducted to assess the effects of soil composition and altitude on morphological and yield traits of three landraces. The experimental investigation used was a completely randomized block design. Morphological and yield traits of the landraces considered in this study varied across agroecology. The variations were due to soil nutrient differences, altitude of the agroecology and their interactions. Soil samples collected from the mid-altitude had the highest pH of 7.71±0.07. Cation exchange capacity of this soil was found to be 45.46±0.71, in covenant with the approximate cation exchange capacity of most soils (>40 CEC meq/100 g soil) around neutral pH. This agroecology was found to be best for overall performance of the landraces. In the highland terrain, the landraces were less vigorous and shorter in height. In the lowland terrain, landraces were taller in height but gave low yield. Gedober 2017 landrace performed best in seed yield (6.00±0.11g/plant) and harvest index (0.32±0.43) at the mid-altitude. From this study, farmers are mindful to cultivate Gedober 2017 landrace at midland and highland pea production potential areas of Ethiopia.

<p>Andisol soil contains a lot of heavy metals Al and Fe, which results in P being unavailable to plants and can cause low soil pH, this will inhibit plant growth. One effort that can be made to increase the availability of nutrients in the soil is by utilizing soil enhancing ingredients enriched with biological fertilizers. The research design used was factorial randomized block design (RBD) consisting of: Factor I: (biological fertilizers) M0 = without application, M1 = <em>Talaromyces pinophilus </em>(Hedgecock), M2 = <em>Azotobacter</em> sp, M3 = Mycorrhizae, M4 = <em>Talaromyces pinophilus</em> + mycorrhizae + <em>Azotobacter </em>sp. Factor II Soil enhancing ingredients, namely P0 = Without Soil Improvement, K1 = Zeolite 50 g, K2 = Humic acid 50 ml, K3 = compost / manure fertilizer for agriculture 50 g. From the results the combination of microbial treatment and soil conditioner can increase nitrogen in the soil by 2-40.81 %, cation exchange capacity by 1.7-44.29 % and P available by 1.3-49.36 %. Soil conditioner combined with biological fertilizers can improve soil quality in general, the best treatment is a combination treatment of <em>T.</em> <em>pinophilus</em> + mycorrhizae + <em>Azotobacter </em>sp. with coffee skin (M4P4).</p>

The present study was carried out during kharif season 2019-20 at the Research Farm, Department of Soil Science & Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh (INDIA), to assess the effect of microbial inoculants on plant attributes and nutrients uptake by soybean in Vertisols. The experiment was laid out under randomized block design (RBD) with three replications. The 15 treatments comprised of different beneficial microbial consortia in possible combinations applied as seed treatments. The crop was supplemented with recommended dose of fertilizers 20 N : 80 P2O5 : 20 K2O kg ha-1. Besides these, two control plots were maintained as fertilized un-inoculated control (FUI) and unfertilized un-inoculated control (UFUI). The findings revealed that the significant improvement were noticed by the application of consortia NPK+EM+PGPR in plant growth attributes of nodulation at 25, 45 & 65 DAS (71, 70 & 59% respectively), over control (9.5, 33.4 & 34.7 nodule plant-1) and its biomass, (62, 69 & 74% respectively),over the control  (0.58, 1.16 & 0.99 g plant-1),  plant height at 25, 45 & 65DAS were increased 61, 40, 41% respectively, over the control (16.20, 34.90 and 44.30 cm) and plant biomass, (48, 62 & 53%), over the control 1.67, 4.73 and 6.1 g plant-1. Similarly, nutrient uptake (seed & stover) were also increased at 25, 45 and 65 stages of crop growth, with 36.6, 34.8 & 51.3% in seed and 66.7, 98.2 & 67.2% in straw respectively over the control (98.5, 63.8, 5.2, and 7.4, 24.9 and 44.4 kg ha-1 respectively). Thus, it may be concluded that the consortium of NPK + EM + PGPR was superior for sustainable crop production and soil health.

<p>An improvement in soil chemical properties and crop development with silicate application has been confirmed in several plant species. The effects of silicate application on soil chemical properties and wheat growth were investigated in the present study. The experiment was carried out in 8-L plastic pots in a greenhouse. Treatments were arranged in a randomized block design in a 3 × 5 factorial: three soils [Rhodic Acrudox (Ox1), Rhodic Hapludox (Ox2) and Arenic Hapludult (Ult)] and five silicate rates (0, 1, 2, 4 and 6 Mg ha–1 of calcium/magnesium silicate), with four replications. The plant length, number of spikes per pot, shoot dry matter and grain yield, were measured after 115 days of wheat (<em>Triticum aestivum </em>L.) growth. Changes in the soil chemical properties (pH, H+ + Al3+, Al3+, P, K, Ca, Mg, Si, Cu, Zn, Fe and Mn) were analyzed after wheat harvest. Application of calcium/magnesium silicate reduces the potential acidity (H+ + Al3+) and Al3+ phytotoxic; and increases the soil pH, available Ca, Mg and Si, cation exchange capacity (CEC) and soil base saturation. Silicate application did not affect the available P, exchangeable K and availability of micronutrients (Cu, Zn, Fe and Mn) in the three soils. The application of calcium/magnesium silicate in an acid clayey Rhodic Hapludox improves the development and yield of wheat; however, the silicate application in soil with pH higher to 5.3 and high Si availability does not affect the agronomic characteristics and grain yield of wheat.</p><p><strong> </strong></p>

The aim of the study is the effect of nitrous oxide (N2O) emissions on rice field. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Sriwijaya University, Indralaya Campus. The N2O gas analysis was conducted at the Laboratory of the Indonesian Agricultural Environment Research Institute, Ministry of Agriculture, Central Java. From April to July 2016. This study used a Randomized Block Design (RBD) with irrigation classes, namely 5 cm (A1), intermittent / intermittent (A2) plots, and saturated land (A3), divided into three (3) groups with a total of 18 treatments, so that there were 54 plots in total. Observation of N2O gas was chosen at weeks 2, 4, 6 and 8 after planting using a closed lid for 24 hours. N2O gas flux is calculated based on an equation adopted from the International Atomic Energy Agency (IAEA). The results obtained are the emission of N2O gas produced by maps with air saturation condition of 5 cm from the surface of the land (A3) in the amount of 1564,554 mg N2O / ha / day and the lowest is produced by inundated plots (A1) with a value of 648,996 mg N2O / ha / day. Soil conditions that are inundated during plant growth produce anaerobic soil conditions capable of lifting N2O flux compared to air-saturated conditions.
