On-Farm Green Manure Cover Crop (GMCC) Intercropping Strategy Trial under Conservation Agriculture

This study contains data originated from on-farm trials that were conducted to provide viable options to smallholder farmers to improve soil fertility and human nutrition, to increase biomass for fodder and groundcover and to enhance the resilience of current farming systems against the negative effects of climate variability and change. Green manures or cover crop were used as the option. The trials were conducted at farms in Chipata and Lundazi districts of the eastern province of Zambia. The following treatments were used for the trial: Sole cropping maize Maize – Pigeonpea intercropping Maize – Pigeonpea intercropping with 60-day cowpea Maize – Dolichos Lablab intercropping Maize/Gliricidia sepium/pigeonpea intercrop (year 1: groundnuts/Gliricidia; Year 2 soybean/pigeonpea/Gliricidia; year 3 Maize/Pigeonpea/Gliricidia本研究的数据源自农户田间试验，旨在为小农户提供可行方案，以改善土壤肥力与人体营养状况、增加饲料与地表覆盖生物量，并提升现有农业系统应对气候波动与气候变化负面影响的韧性。试验采用绿肥（green manures）或覆盖作物（cover crop）作为改良措施。试验于赞比亚东部省奇帕塔（Chipata）与隆达齐（Lundazi）地区的农户农场开展。试验设置如下处理组：单作玉米；玉米-木豆（pigeonpea）间作；玉米-木豆间作配植60天生长期豇豆（cowpea）；玉米-镰扁豆（Dolichos Lablab）间作；玉米/灰叶豆（Gliricidia sepium）/木豆间作体系（第1年：花生（groundnuts）/灰叶豆；第2年：大豆（soybean）/木豆/灰叶豆；第3年：玉米/木豆/灰叶豆）
