Abstract

A proper protocol of efficient irrigation and nutrient management for ginger is a necessity for boosting the productivity and quality of the crop in high-intensity cultivated lands. For this, a field experiment for 3 consecutive years was conducted in an Inceptisol of India to optimize irrigation schedule and nutrient management for augmenting rhizome yield and crop water productivity (CWP) of ginger. The trial was laid out in a split plot design with 12 treatment combinations consisting of 4 levels of irrigation schedules viz., rainfed (I1) and a ratio of 0.6 (I2), 0.9 (I3) and 1.2 (I4) of irrigation water to cumulative pan evaporation (IW/CPE) and 3 levels of nutrient management: 100% recommended dose of fertilizer (RDF) through inorganic (N1), 75% RDF (inorganic) + 25% RDF through vermicompost (VC) (N2) and 50% RDF (inorganic) + 50% RDF through VC (N3). Mean maximum growth and yield components, quality parameters, green rhizome yield (12.63 Mg‧ha−1) and highest nutrient uptake were obtained with I4N2, which was statistically on par with I3N2. The treatment combination I1N2 exhibited maximum CWP. Well-managed irrigation and nutrient scheduling is key to improving ginger production and its marketability for better financial returns.

通过灌溉和养分管理改善生姜的生长、产量和品质:来自印度Inceptisol的研究

合理的生姜灌溉和养分管理方案是提高高集约化耕地生姜产量和品质的必要条件。为了提高生姜根茎产量和作物水分生产力(CWP)，在印度Inceptisol进行了连续3年的田间试验，优化灌溉计划和养分管理。试验采用分畦设计，采用12种处理组合，包括4个水平的灌溉计划，即雨养(I1)，灌溉水与累积蒸发量(IW/CPE)的比例为0.6 (I2)、0.9 (I3)和1.2 (I4); 3个水平的养分管理:100%推荐剂量的肥料(RDF)(无机)(N1)， 75% RDF(无机)+ 25% RDF (VC) (N2)和50% RDF(无机)+ 50% RDF (VC) (N3)。I4N2处理的平均最大生长和产量成分、品质参数、绿根茎产量(12.63 Mg·ha−1)和养分吸收量最高，在统计学上与I3N2相当。处理组合I1N2表现出最大CWP。管理良好的灌溉和养分调度是提高生姜产量及其市场销售能力以获得更好经济回报的关键。
