Impact of Integrating Annual and Perennial Legumes under Coffea arabica on Sloping Land
نویسندگان
چکیده
Above-ground biomass cover under Coffea arabica on sloping land is beneficial but difficult to sustain. Interplanting annual and perennial legumes can sustain the above-ground cover, improve soil fertility, yield, profitability. This was tested 26 farms in a four-growing season experiment undersowing C. with new crop combinations: Mucuna pruriens var. utilis (T1); Millettia dura Dunn (T2); combination of M. (T3); control no-cover legume (T4). On each farm, all treatments followed randomized single-block design. T3 produced 8.7 mt/ha/yr that significantly (p < 0.01) higher than other increasing seasons. Under T3, plant-available nitrogen (N) potassium (K) increased more treatments. During fourth season, coffee yield 54%, 22%, 11% T4, T2, T1, respectively. The gross profit 86% T4 season. indicates interplanting sustainably increase soil’s N K, Based results, recommended optimize production described conditions.

Perennial-like adaptation mechanisms of annual legumes to limited irrigation.
The hydrodynamic behavior of two annual legumes (Trifolium angustifolium L. and Onobrychis caput-galli (L.) Lam.) under water shortage was studied in a rain shelter experiment. Seeds were collected from natural grasslands of northern Greece and were sown in pots. Two months after seedlings' emergence, full irrigation (up to field capacity) and limited irrigation (40% of field capacity) were app...
متن کاملThe Impact of Climate Change on Indigenous Arabica Coffee (Coffea arabica): Predicting Future Trends and Identifying Priorities
Precise modelling of the influence of climate change on Arabica coffee is limited; there are no data available for indigenous populations of this species. In this study we model the present and future predicted distribution of indigenous Arabica, and identify priorities in order to facilitate appropriate decision making for conservation, monitoring and future research. Using distribution data w...
متن کاملEndophytic bacteria in Coffea arabica L.
Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, ...
متن کاملBiosynthesis of chlorogenic acids in growing and ripening fruits of Coffea arabica and Coffea canephora plants.
Chlorogenic acids are major secondary metabolites found in coffee seeds. The accumulation of chlorogenic acids and free quinic acids was studied in Coffea arabica cv. Tall Mokka and Coffea canephora seeds. Growth stages are specified from I to V, corresponding to rapid expansion and pericarp growth (I), endosperm formation (II), mature (green) (III), ripening (pink) (IV), and fully ripened (red...
متن کاملIdentification of novel and conserved microRNAs in Coffea canephora and Coffea arabica
As microRNAs (miRNAs) are important regulators of many biological processes, a series of small RNAomes from plants have been produced in the last decade. However, miRNA data from several groups of plants are still lacking, including some economically important crops. Here microRNAs from Coffea canephora leaves were profiled and 58 unique sequences belonging to 33 families were found, including ...
