<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>

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.

A field experiment was conducted for two years (2007 and 2008) at the G. B. Pant University of Agriculture and Technology, Pantnagar, to study the productivity, biological efficiency and economics of intercropping in spring maize (Zea mays L.) with sunflower (Helianthus annuus L.) and urdbean (Vigna mungo L.) under different spatial arrangements. The experiment consisting of ten treatments i.e. three sole crops (maize, sunflower and urdbean), six replacement intercropping system of maize with each sunflower and urdbean in row ratios of 1:1, 2:1 and 3:1 and one additive intercropping system of maize with urdbean in row ratios of 1+1 was laid out in randomized block design with three replications. The intercropping system of maize with urdbean in row ratio (1+1) was found beneficial over sole cropping of maize and gave the maximum maize-equivalent yield (5847 kg ha-1), land-equivalent ratio (1.36) and net return (Rs.13420 ha-1). Intercropping of maize in replacement arrangement was not productive and advantageous than respective sole crops. DOI: http://dx.doi.org/10.3329/sja.v12i1.21110 SAARC J. Agri., 12(1): 26-32 (2014)
