“…Integrated nutrient management (INM) is a holistic approach and can be defined as the maintenance and regulation of soil fertility and plant nutrient supply to an optimum level in an integrated manner. It is based on the combination of organic, inorganic, and biological nutrient sources in a specific cropping system under consideration of local conditions to achieve and sustain optimum yield without harming the soil ecosystem [89,[112][113][114]. Beside the positive effects on the soil nutrient status, INM can also enhance soil organic matter and increase the retention and storage of water [17,115].…”

Challenges of Smallholder Farming in Ethiopia and Opportunities by Adopting Climate-Smart Agriculture

Agriculture is the backbone of the Ethiopian economy, and the agricultural sector is dominated by smallholder farming systems. The farming systems are facing constraints such as small land size, lack of resources, and increasing degradation of soil quality that hamper sustainable crop production and food security. The effects of climate change (e.g., frequent occurrence of extreme weather events) exacerbate these problems. Applying appropriate technologies like climate-smart agriculture (CSA) can help to resolve the constraints of smallholder farming systems. This paper provides a comprehensive overview regarding opportunities and challenges of traditional and newly developed CSA practices in Ethiopia, such as integrated soil fertility management, water harvesting, and agroforestry. These practices are commonly related to drought resilience, stability of crop yields, carbon sequestration, greenhouse gas mitigation, and higher household income. However, the adoption of the practices by smallholder farmers is often limited, mainly due to shortage of cropland, land tenure issues, lack of adequate knowledge about CSA, slow return on investments, and insufficient policy and implementation schemes. It is suggested that additional measures be developed and made available to help CSA practices become more prevalent in smallholder farming systems. The measures should include the utilization of degraded and marginal lands, improvement of the soil organic matter management, provision of capacity-building opportunities and financial support, as well as the development of specific policies for smallholder farming.

“…Among the different maize parameters, ear length is a vital parameter that contributes to yield; it significantly influences both the number of grains per ear and the size of the maize grain yield. Thousand-grain weight is essential among the numerous parameters promoting the commercial maize yield (Yigermal et al, 2019).…”

Reducing greenhouse gas emissions and increasing agronomic productivity by sustaining soil organic matter and refining soil fertility have become the main concerns for agricultural scientists. There is a new approach to decrease greenhouse gas emissions, soil C sinks, and improve soil quality using biochar. Soil acidification is improved by applying lime or other acid-neutralizing materials. Additionally, Ca and Mg can increase by applying lime. The availability of Ca, Mg, and K in the soil is significantly affected by the application rate of biochar spread separately or combined with chemical fertilizers. Soil nutrients and maize (Zea mays L.) yield are highly influenced by the use of lime and biochar. Biochar can improve the ecosystem by reducing soil CO2 emissions from agricultural practices. The inconsistent results and clarifications from various studies highlight the importance of relating the impact of different biochar rates on CO2 emissions and maize yield. This review summarizes the properties of biochar, provides the scientific reference for its application to achieve high and good quality maize and reduce CO2 emissions.

“…In the case of NPK+FYM, supply of additional 87 kg N, 31 kg P, 67 kg K, 36 kg S, 282 kg Ca, 186 kg Mg, 16 kg Fe, 9 kg Mn, 884 g Zn, 182 g Cu and 173 g B ha -1 year -1 through FYM improved availability of those nutrients in soil (Table 4) and in turn rice yield as compared to the NPK alone. Reports of integrated NM for sustainable crop harvest are available across cropping systems, soil type and climatic region [51][52][53][54][55][56]4].…”

Maintenance of soil quality is considered to be the key to attain sustainability in agricultural production and thus to achieve food security. In this study we tried to answer a research question as to whether integrated application of inorganic and organic sources of nutrients can maintain productivity and soil quality in rice-rice cropping system. To address this, total 27 physical, chemical (including organic C and soil fertility parameters) and biological (including enzyme activities) properties of an acidic sandy loam soil, which were subjected to different nutrient management (NM) practices for nine years of rice-rice cropping under submergence in subtropical India were critically assessed. Seven NM practices comprised of organic [farmyard manure (FYM)], inorganic fertilizers (sources of N, P, K, S, Zn, and B) and some of their combinations were tested using randomized complete block design with four replications. Integrated use of inorganic fertilizers (NPK) and organic manure (FYM) sustained productivity of rice-rice cropping system and aggraded soil quality as compared to only inorganic fertilizers even with inclusion of S, Zn and B. The NPK+FYM was superior among the NM practices to improve physical, chemical and biological properties of soil. Cation exchange capacity, non-exchangeable K and microbial biomass C were screened as the most sensitive attributes for assessing soil quality. Although the present study demonstrated the positive influence of integrated NM, application of even 80-17.5-50 kg N-P-K along with 5 Mg FYM ha-1 in each rice season failed to maintain total K content in soil. This suggested for readjustment of dose of inorganic fertilizers and organic manure and their application schedule for adequate replenishment of K in acidic sandy loam soil under rice-rice cropping in subtropical climate.
