The growth response of coffee (Coffea arabica L) plants to organic manure, inorganic fertilizers and integrated soil fertility management under different irrigation water supply levels

Abstract

A study was carried out to determine the effects of organic, inorganic fertilizers and integrated soil fertility management and irrigation levels (1,000, 750 and 500 ml per planting station) on coffee growth. There were no significant differences (p [ 0.05) in girth, number of leaves and number of primaries due to the different soil fertility management options. Significant differences (p \ 0.05) due to soil nutrient sources were observed in coffee height where inorganic fertilizer treatment resulted in tallest coffee plants (47.4 cm) and integrated soil fertility having the shortest coffee trees (42.8 cm) after 1 year. The highest irrigation level of 1,000 ml had the tallest plants with thickest stems while the lowest level had the shortest and thinnest plants (p \ 0.05). No significant differences were observed in the number of leaves and number of primaries due to irrigation treatments. Results indicate that inorganic fertilizers are the most effective at high irrigation levels while organic manure performs better than inorganic fertilizers under low irrigation water levels.

Comparison of traditional and modern deficit irrigation techniques in corn cultivation using treated municipal wastewater

“…9). Chemura (2014) showed in the research on coffee, irrigation water amounts in terms of height have significant effect (p \ 0.05). Coffee plants were tallest and thickest plant stems when supplied the more irrigation water levels (1000 ml) and shortest and thinnest under the lowest irrigation amounts (500 ml) because of inorganic fertilizers are the most effective at high irrigation levels while organic manure performs better than inorganic fertilizers under low irrigation water amount.…”

“…Also, in cases of drought, nutrients are not easily available from inorganic sources of soil nutrients for plant (Chemura 2014). New innovations are particularly important in waterscarce regions with the aim of saving irrigation water, and thereby increasing crop WUE (Gencoglan et al 2006).…”

Nutrient accumulation in bean and fruit from irrigated and non-irrigated Coffea canephora cv. Conilon

“…The need for renewable options, available in-situ and lower cost for the supply of nutrients for the crop is increasingly important due to the need for more sustainable agriculture (Chemura, 2014). By knowing the amounts of allocated nutrients in Conilon coffee tissues, valuable information can be gathered to assist the planning of the coffee crop fertilization program, as well as its use as a complement to conventional fertilization.…”

Cultivable bacterial diversity and early plant growth promotion by the traditional organic formulations prepared using organic waste materials

“…Nonetheless, biofertilizers or traditional organic formulations prepared by using organic materials/wastes are encouraged to use as a plant nutrition (Badgley et al 2007). Numerous studies stated that the yield and quality of plant products produced by organic farming are considerably better than that of conventional farming (Chemura 2014;Oliveira et al 2013;Luthria et al 2010). Organic farming not only improves the quality of the food products, but it also improves the soil fertility.…”
