Effect of Biochar Application on Growth of Garden Pea (Pisum sativumL.) in Acidic Soils of Bule Woreda Gedeo Zone Southern Ethiopia

Abstract

The aim of this experiment was to study the effect of types and rates of biochar on growth, yield, and yield component of garden pea at Bule wereda, Southern Ethiopia. The treatments consist of two types of biochar (corncobs and Lantana camara) and four rates of biochar (0, 6, 12, and 18 t ha−1). The experiment was laid out as a randomized complete block design in a factorial arrangement with three replications. Soil samples were collected at a depth of 0–30 cm and germination parameter and phonology of garden pea were recorded. The result showed that soil bulk density, porosity, pH, and exchangeable acidity were significantly (P<0.001) affected by biochar application. The result also showed that maximum germination percentage of garden pea seeds (95.23%) was recorded at 18 t ha−1 of Lantana biochar. The shoot length was significantly (P<0.05) affected at 15 days and 30 days of biochar application. Moreover, fresh shoot weight and dry root biomass, number of seeds per pod, and grain yield of garden pea were significantly affected (P<0.05). Of the substrate and application rate applied, Lantana camara 12 t ha−1 and Lantana camara 18 t ha−1 significantly increased yield of garden pea. Thus, further studies on effect of different biochars and their specific role are suggested to increase crop production.

Morpho-Physiological Responses of Pisum sativum L. to Different Light-Emitting Diode (LED) Light Spectra in Combination with Biochar Amendment

“…For most of the morphological traits, and independently of the light spectra, we generally observed a positive effect on seedlings grown in the presence of biochar. This finding is in accordance with observations reported by Berihun et al [65], who related such variations in plant morphology to the improved substrate characteristics after biochar application. Indeed, among many factors, organic matter (total carbon) and nitrogen content are most likely to have a beneficial impact on substrate quality [66].…”

“…In our study, together with a significant increase in total carbon and nitrogen availability measured in biochar-amended substrate, a higher fruit mass, both fresh and dry, was detected. These findings are in line with previous studies that highlighted an indirect promotion of fruit productivity related to biochar application [65,67,68]. Alternatively, Solaiman et al [69] ascribed the enhancement in growth of bean plants by biochar application to the increase of substrate pH and nutrient availability.…”

A review on biochar as a potential soil fertility enhancer to agriculture

“…Inclusion of biochar enhances plant growth by expanding the accessibility of basic nutrients (N,P,K etc.) in soil and their eventual take up by plants (Berihun et al, 2017;Lehmann, 2007). Biochar has constructive outcome on crop yield in general, and it is more effective when applied to degraded, low fertile soil rather than nutrient rich healthy soil (El-Naggar et al, 2018).…”

Long term effect of Fertdolomite on soil, maize and wheat status on acid soil of eastern Croatia

“…Usually the materials for liming were calcium oxide (CaO), calcium hydroxide (Ca(OH)2), calcium carbonate (CaCO3), calcium magnesium carbonate (CaMg(CO3)2) or some other calcium complex (Meriño-Gergichevich et al, 2010). However, some other materials can be Original scientific paper DOI: /10.5513/JCEA01/20.1.2140 Iljkić et al: Long term effect of Fertdolomite on soil, maize and wheat status on acid soil... used for decreasing soil acidity such as steel slag (Plopeanu et al, 2017), biochar (Berihun et al, 2017), wood ash and filter dust (Ivezić et al, 2017). Under environmental conditions of Croatia and Bosnia and Herzegovina the positive effects of liming on soil status, field crops yield and quality were found (Markovic et al, 2008;Andric et al, 2012;Kovačević et al, 2015).…”
