Indonesia has several specialty coffee that have been marketed domestically and exported to foreign countries. The current focus of specialty coffee development is increasing production and quality of domestic coffee by paying attention to aspects of local wisdom. This review article was aimed to discuss several agronomical measures should be applied by coffee farmers in Indonesia. It is hoped that this effort will enrich the variety of high-value specialty coffees from various regions. To obtain specialty coffee products with good quality, coffee cultivation techniques that are in accordance with good agricultural practices (GAP), environmentally friendly, as well as adaptive to climate change, need to be supported. Therefore, it is necessary to apply sustainable coffee cultivation by 1) replanting and rejuvenating of coffee plantations using novel resilient cultivars, 2) planting shade trees, 3) pruning, 4) using organic fertilizer and biofertilizer, 5) rainwater harvesting and irrigation systems, 6) integrated pest, desease, and weed management, and 7) selective cherry harvest.

“…In the field, Araújo et al (2013) used organic compost-based fertilizer in quantities sufficient to supply 25, 50, 75, and 100 % of the N requirement for the coffee plant. They supplemented it with 450 g of dry C. juncea labelled with 15 N at 11 and 22 months after planting.…”

The coffee sector is estimated to have a retail market value in excess of USD 83 billion, and over 125 million jobs have been created in the global coffee chain. The coffee specialty market has recently increased significantly, generating opportunities to certify coffee beans produced by sustainable practices. This avoids practices potentially harmful to the environment. Agroforestry, organic farming, intercropping, and soil conservation strategies are examples of sustainable alternatives in the production of coffee. In this review, we focus on practices for the sustainable management of coffee plantations that can help farmers fight problems caused by global warming. More specifically, we address soil organic matter and microbiota, the use of Urochloa grass as intercrop in coffee plantations, shading systems (including agroforestry), and organic coffee production. We concluded that from the agronomic viewpoint, we already have production techniques that can replace traditional ones with significant advantages accruing to the quality of coffee orchard ecosystems. Nevertheless, we need scientific research efforts to deal with the existing gaps and the engagement of the whole coffee chain as a means of guaranteeing an adequate profit to those smallholders who adopt and maintain sustainable practice and are capable of bringing several positive changes to the coffee crop, including the use of microbia-based commercial products and new organic sources of nutrients to complement chemical fertilizers and improve coffee quality.

“…O cultivo da C. juncea em consorciação, rotação e sucessão é muito estudado, obtendo resultados positivos no aumento da produção, controle de ervas daninhas e diminuição do uso de fertilizantes nitrogenados em diferentes culturas: milho (KAPPES et al, 2015;RUGARE;PIETERSE;MABASA, 2019;SANTOS et al, 2010;WUTKE et al, 2014), trigo (LANGE et al, 2009WUTKE et al, 2014), maracujá (DANTAS et al, 2019, pimentão (TIVELLI et al, 2013), cana-de-açúcar (DUARTE JÚNIOR;COELHO, 2008;WUTKE et al, 2014), café (ARAUJO et al, 2013;WUTKE et al, 2014).…”

Normalized Difference Vegetation Index (NDVI) to estimate green manure phytomass Fabaceae are the most commonly used species in green manure due to their ability to fix atmospheric nitrogen from the process of symbiosis with diazotrophic bacteria. Estimating its yield allows the producer to correctly manage fertilization for crops in rotation or succession. The present work aimed to monitor the vegetative development of green manures over time, through the Normalized Difference Vegetation Index (NDVI), to estimate its phytomass production. The experimental design was in randomized blocks with subplots; the plots were composed of six green manures, Crotalaria juncea L. (Sunn hemp), Crotalaria spectabilis Roth. (Showy crotalaria), Crotalaria ochroleuca L. (Sunn hemp), Cajanus cajan (Pigeon pea), Canavalia ensformis (L.) D.C. (Jack bean) and Panicum maximum Jacq. and the subplots were the evaluation times production phytomass (30, 40, 50, 60, 70 and 90 days after emergence-DAE), with four replicates. Green manures were conducted during the vegetative phase-until 90 DAE, NDVI evaluations were performed twice a week. The green manures showed satisfactory development within the cultivated period with NDVI values obtained over time presenting maximum values between 55 and 69 days, ranging from 0.77 to 0.91. C. spectabilis, P. maximum, C. cajan and C. ochroleuca showed a strong correlation between NDVI and phytomass production, while C. ensiformis and C. juncea presented moderate correlation with NDVI and phytomass. The active optical sensor allows to estimate its production, with precision varying according to the species.
