“…Results from field trials in Ethiopian soils showed positive crop responses to K application. For example, coffee yield increased from 1 038 kg ha −1 in the control without K to 1 311 kg ha −1 when K was applied at 62 kg ha −1 in Jimma (Melke and Ittana, 2015). Haile and Boke (2011) also reported that increasing the level of K application to 150 kg ha −1 increased tuber yield from 18 t ha −1 in the control (no application) to 53 t ha −1 .…”

Integrated Soil Fertility and Plant Nutrient Management in Tropical Agro-Ecosystems: A Review

The greatest challenge for tropical agriculture is land degradation and reduction in soil fertility for sustainable crop and livestock production. Associated problems include soil erosion, nutrient mining, competition for biomass for multiple uses, limited application of inorganic fertilizers, and limited capacity of farmers to recognize the decline in soil quality and its consequences on productivity. Integrated soil fertility management (ISFM) is an approach to improve crop yields, while preserving sustainable and long-term soil fertility through the combined judicious use of fertilizers, recycled organic resources, responsive crop varieties, and improved agronomic practices, which minimize nutrient losses and improve the nutrient-use efficiency of crops. Soil fertility and nutrient management studies in Ethiopia under on-station and on-farm conditions showed that the combined application of inorganic and organic fertilizers significantly increased crop yields compared to either alone in tropical agro-ecosystems. Yield benefits were more apparent when fertilizer application was accompanied by crop rotation, green manuring, or crop residue management. The combination of manure and NP fertilizer could increase wheat and faba bean grain yields by 50%-100%, whereas crop rotation with grain legumes could increase cereal grain yields by up to 200%. Although organic residues are key inputs for soil fertility management, about 85% of these residues is used for livestock feed and energy; thus, there is a need for increasing crop biomass. The main incentive for farmers to adopt ISFM practices is economic benefits. The success of ISFM also depends on research and development institutions to provide technical support, technology adoption, information dissemination, and creation of market incentives for farmers in tropical agro-ecosystems.

“…Ethiopia holds a unique position in the world as C. arabica L. has its primary centre of diversity (Melke and Ittana, 2015). And the present study on the effect of soil nutrient ratios on coffee quality has wider importance since the natural coffee forests of Ethiopia is a birthplace of wild Arabica coffee, and the information obtained from this study can be used as a model for simulating suitable soil conditions such as nutrient balances for improving coffee quality and for expanding commercial production of Arabica coffee in other parts of the country or elsewhere.…”

“…Mineral nutrients are essential for plant growth and development through the incorporation of these mineral nutrients into organic substances such as pigments, enzyme cofactors, lipids, nucleic acids, and amino acids (Taiz and Zeiger, 2002). And hence nutrients influence the chemical composition and the sensory quality of plant products (Wiesler, 2012;Melke and Ittana, 2015). Nutrients are accumulated by the fruit during its development, and coffee fruits/beans are strong sinks for minerals and carbohydrates (Covre et al, 2016), which affect it quality.…”

“…Plants require nutrients in balanced amounts (Roy et al, 2006;Hall, 2008), and nutrient interactions are very important aspect in mineral nutrition of plants (Clark and Baligar, 2000;Fageria, 2009). Proper coffee nutrition is thus required since it affects coffee quality and the overall productivity of the crop (Melke and Ittana, 2015). It is hypothesized that soil nutrient ratios (nutrient balances) in coffee plots from the natural coffee forest ecosystems are distinct since these Afromontane rainforests are the origin of Arabica coffee.…”

Nutrients are essential for plant growth and development, and soil nutrient ratios play key roles in coffee quality. The objective of this study was to investigate the influence of soil nutrient ratios on the quality of wild Arabica coffee in Ethiopia. Results revealed that the balance between the soil nutrients was well correlated with coffee quality attributes. The balance between magnesium and calcium (Mg:Ca) and the balance between nitrogen and phosphorus (N:P) were found to be very important factors for bean size. Increase in Ca relative to Mg increased bean size, and vice versa. The higher the concentration of available P in relation to soil organic carbon (P:C) or total N (P:N), the better the cup quality of the coffee, and vice versa. The Mg:K ratio, P:N ratio, P:C ratio and P:Zn ratio were very important factors for cup quality. Although the ratio between Mg and K was important for cup quality, it was not apparent for bean size. The ratio between Ca and Mg was of no or little importance for coffee cup quality as opposed to that of bean size. Therefore, coffee growers should make careful decisions depending on the demands of the buyers/consumers and environmental requirements.

ABSTRAKMikoriza merupakan agens hayati yang dapat meningkatkan efisiensi penggunaan pupuk kimia (anorganik) karena dapat meningkatkan ketersediaan unsur hara tanah. Penelitian bertujuan mengevaluasi efektivitas mikoriza dan pupuk NPKMg terhadap pertumbuhan dan hasil tanaman kopi muda di lapangan. Penelitian dilaksanakan di KP. Pakuwon, Sukabumi, Jawa Barat, mulai Januari 2013 sampai November 2014. Perlakuan yang diuji adalah penggunaan mikoriza 3 taraf: tanpa mikoriza, 200 spora/pohon, dan 400 spora/pohon; dan pemberian pupuk NPKMg, 4 dosis (dosis rekomendasi, ¾, ½, dan ¼ dosis rekomendasi). Perlakuan disusun dalam rancangan acak kelompok, 3 ulangan dengan ukuran petak 4 pohon. Dosis rekomendasi adalah pemberian pupuk NPKMg sebanyak 140 g/pohon/tahun (40 g urea, 50 g SP-36, 30 g KCl, dan 20 g kieserit). Pupuk NPKMg diberikan dalam 2 tahap, sedangkan mikoriza diaplikasikan dua bulan setelah pemberian pupuk NPKMg yang pertama. Parameter yang diamati meliputi karakter vegetatif (tinggi tanaman, diameter batang, dan jumlah cabang) dan generatif (hasil kopi) serta tingkat infeksi mikoriza pada akar kopi. Hasil penelitian menunjukkan pemberian kombinasi mikoriza 400 spora dan 105 g NPKMg per pohon/tahun menghasilkan pertumbuhan tanaman kopi terbaik sampai umur 15 bulan setelah tanam, tetapi belum berpengaruh terhadap produksi kopi. Pemberian inokulum mikoriza sebanyak 200 dan 400 spora/pohon memperlihatkan tingkat infeksi mikoriza yang sama pada akar kopi pada semua pemberian dosis pupuk.Kata kunci: Kopi Arabika, mikoriza, pupuk NPKMg/tree/years (40 g urea, 30 g KCl, and 20 g kieserit ABSTRACT Mycorrhiza is a biological agent that could improve the efficiency of chemical fertilizers (inorganic) due to it can increase the availability of soil nutrients. The study aimed to evaluate the effectiveness of mycorrhiza and NPKMg fertilizers on growth and yield of coffee plants in the field. The research was carried out at KP. Pakuwon, Sukabumi, West Java, from January 2013 to November 2014. The treatments that examined in this study were 3 levels of mycorrhiza application (M0, without mycorrhizal fungi; M1, application of 200 spore/tree; and M2, application of 400 spore/tree), and 4 dosage of NPKMg fertilizers (F1, recommended dose, RD; F2, ¾ RD; F3, ½ RD, and F4, ¼ RD). The treatments were arranged in a ramdomized block design with 3 replications, and the plot size consisted of 4 coffee plants. The recommended dose of fertilizer is 140 g
