“…Keberadaannya dalam jaringan tanaman mempengaruhi penyerapan unsur penting lain yang menentukan dalam proses pertumbuhan dan perkembangan tanaman kopi selanjutnya (Silva, Lima, & Bottega, 2013). Namun, kandungan P yang berlebih (sangat tinggi) seperti di lokasi penelitian (Tabel 2) akan mempercepat proses pematangan buah sehingga pengisian biji tidak optimal, akibatnya ukuran biji mengecil dan beratnya berkurang (Somporn et al, 2012;Martins et al, 2015).…”

ABSTRAKKetinggian tempat mempengaruhi unsur-unsur iklim yang akan berdampak terhadap sifat kimia tanah. Pertumbuhan, produktivitas, mutu, dan citarasa kopi ditentukan oleh beberapa faktor, salah satunya sifat kimia tanah. Tujuan penelitian adalah menganalisis korelasi antara ketinggian tempat, sifat kimia tanah, dan mutu fisik biji kopi Arabika di dataran tinggi Kabupaten Garut. Penelitian dilakukan di dataran tinggi Kabupaten Garut, Provinsi Jawa Barat, mulai bulan April sampai Agustus 2014. Penelitian menggunakan metode survei dengan pemilihan lokasi dan ketinggian tempat secara purposive serta pengambilan sampel tanah dan biji kopi secara acak di masing-masing lokasi. Parameter yang diamati adalah sifat kimia tanah, persentase biji normal, dan berat biji kopi Arabika pada ketinggian tempat 1.000-1.600 m dpl. Data dianalisis menggunakan korelasi. Hasil penelitian menunjukkan korelasi yang nyata antara ketinggian tempat dengan beberapa sifat kimia tanah dan mutu fisik biji kopi Arabika di dataran tinggi Garut. Semakin tinggi tempat maka semakin meningkat pula sifat kimia tanah seperti pH, C-organik, N-total, Na, dan KTK, tetapi sebaliknya untuk P 2 O 5 total. Meningkatnya tinggi tempat dan beberapa sifat kimia tanah tersebut seiring dengan meningkatnya pula persentase biji normal dan berat 100 biji kopi Arabika.

“…The nutritional content in plant tissues; the efficiency in which the plants acquire, translocate and utilize the nutrients; and tolerance to cultivation in environment with low fertility have all been successfully used as parameters to study the variability among genotypes of C. canephora and to identify groups with different traits (Martins et al, 2013a;2013b;Colodetti et al, 2014;Machado et al, 2016;Martins et al, 2015b;Starling et al, 2018). Differences among genotypes were observed for the content of all macronutrients in green tissues, and the magnitude of the genetic parameters showed that nutritional contents can be greatly influenced by the genetic constitution (Table 1).…”

Coffea canephora shows considerable variability for several agronomic traits, including nutritional efficiency. Beside the intrinsic nutritional efficiency of a genotype, the availability of water in the soil is another factor that can cause different responses, which suggests the possibility of selection of genotypes to enhance the nutritional efficiency under different scenarios, such as plantings in areas with low natural fertility or subjected to drought. We evaluated the genetic diversity of genotypes of C. canephora that compose the cultivar "BRS Ouro Preto", the first available clonal cultivar recommended for Rondonia State, based on parameters of nutritional status of the plants subjected to cultivation under conditions of abundant water supply or subjected to water deficit. To this end, the experiment was developed with two trials where the 15 genotypes of this cultivar were cultivated in a greenhouse, under conditions of abundant water supply or subjected to water deficit. The trials followed a completely randomized design, with four replications and the mineral status of the plants was evaluated based on the content of N, P, K, Ca, Mg and S of their green tissues. The genotypes ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (2): gmr18300 L.C.T. Starling et al. 2presented high variability for these nutritional parameters, making it possible to identify distinct patterns and to group them according to their nutritional status. Variability was affected by drought, showing that the water supply can cause changes in patterns of nutritional status and affect the clustering of genotypes. The genotypic effect surpassed the environmental influence for most mineral parameters, resulting in a desirable scenario for a possible selection to enhance nutritional efficiency, for both irrigated and rainfed systems, within the group of genotypes that already present high yield in Rondonia state.

“…Differences in the nutritional efficiency among genotypes of conilon coffee have been reported in several studies (Martins et al, 2013a(Martins et al, , 2015a(Martins et al, , 2015b. Scientific results indicate that N and P supply in the soil can cause alterations in the biomass allocation patterns, making it possible to discriminate genotypes by their tolerance to the deficit of these nutrients in the soil (Colodetti et al, 2014;Martins et al, 2013bMartins et al, , 2015b.…”

“…Among the species of the genus Coffea, the species Coffea arabica, Coffea canephora and Coffea liberica have been widely cultivated for beverage production (Ramalho et al, 2013). During the last decade, the cultivation of C. canephora has been greatly contributing to the increase in the worldwide production of coffee, which has been increasing the need for scientific and technologic advances for the management of genotypes There is wide intra and interspecific variability among genotypes of C. canephora, mainly in characteristics as growth rate, drought tolerance, ripening cycle and crop yield (Ferrão et al, 2008;Fonseca et al, 2004;Marraccini et al, 2012;Martins et al, 2015a;Rodrigues et al, 2012); conferring to conilon coffee, a great possibility of exploration, by means of identifying genetic material adapted to diverse conditions of soil and weather (Martins et al, 2015b). Therefore, the need to understand aspects of the nutritional demand and efficiency of genotypes to use and convert the taken nutrients is undeniable (Martins et al, 2013a;Partelli et al, 2014); however, the breeding programs have not been considering the nutritional efficiency as a selection criterion to identify superior genotypes of conilon coffee worldwide.…”

The objective of the study was to differentiate genotypes with higher efficiency and responsiveness to nitrogen supply, to understand how the nitrogen supply can impact the dry matter allocation and the accumulation of this nutrient in the different plant compartments of genotypes of conilon coffee, cultivated under contrasting conditions of nitrogen availability in the soil. The plants were cultivated during 150 days in pots containing 10 kg of soil, in greenhouse. The experiment was set up in a 13×2 factorial scheme, following a completely randomized design (CRD) with three replications. The factors were: 13 genotypes and two levels of nitrogen fertilization (0 and 100% of the N recommended level). The N supply increased between 70 and 210% of the total dry matter and between 360 and 680% of the concentration of N content in leaves of the genotypes of conilon coffee. It was possible to observe that the expression of the genotypes was modulated by the availability of N in the soil, since they presented different behaviors in the studied environments (with 0 or 100% of N supply in the soil). The genotypes CV-03, CV-07 and CV-08 were classified as non-efficient and non-responsive, while the genotypes CV-01, CV-04 and CV-09 of conilon coffee were classified as efficient and responsive.
