Abstract

West Lampung Regency still survives as the central area of coffee production in Lampung Province while production of other districts so far are declining. This research aims to study the ethno-agronomy of coffee cultivation in West Lampung which is tolerant to rainfall variability. This research was a survey located in Sumberjaya District and Sekincau District, West Lampung Regency, Lampung Province, Indonesia year 2018—2019 which from each subdistrict two villages was selected purposively and from each village one farmer group was chosen. Primary data were collected through interview, Focused Group Discussion (FGD), and observation of coffee farm. Secondary data were obtained from the BPS Lampung and rainfall data from Radin Intan Climate Station. The results showed that the area of coffee plantations in West Lampung in the last decade has decreased by 0,64% per year but productivity has increased by 1,42% per year, and in West Lampung, which is a mountainous region, the number of rainy days was negatively correlated with coffee yield while the number of dry months was positively correlated. Whereas in North Lampung, which is a medium elevation area, coffee productivity correlated with sufficient rainfall and productivity was negatively correlated with the number of dry months of the previous year. Coffee farmers in West Lampung have perception the need for various adaptation measures of coffee farm maintenance, which grafting adult coffee tree with superior local robusta clones is a typical ethno-agronomy practiced by coffee farmers in West Lampung to obtain high coffee yield.

Abstract

Tillage can significantly affect soil susceptibility to erosion which can accelerate and increase the rate of erosion. The use of mulch can reduce erosion by reducing the impact energy of falling rain so it does not damage the structure and aggregate of the soil, reducing speed, volume and scouring of surface runoff. This study aims to determine the effect of (1) tillage systems on surface runoff and erosion in green bean plant  (2) applying organic mulch to the amount of surface runoff and erosion in green bean plant  (3) the interaction between the tillage system and the use of mulch on surface runoff and erosion in green bean plant . This research was conducted in March to June 2017 in the Integrated Field Laboratory of the Faculty of Agriculture, University of Lampung. The design used is factorial in the Complete Randomized Block Design (RCBD) on two treatment factors namely the tillage system and the mulch with four replications. The results showed that the tillage system did not significantly affect all observed variables. In the treatment of giving and without mulch also did not significantly affect all observed variables. The response of surface runoff and erosion in green bean plant  to the tillage system does not depend on the organic mulch shown on all variables.
