Abstract

Background: This study aimed to evaluate the growth performance, biomass production and nutrient accumulation of three abundant leguminous weeds, namely Crotolaria micans Link., Aeschynomene indica L. and Calopogonium mucunoides Desv., found in Mizoram, India, to assess their potentiality as green manure crops. Methods: The field experiment was conducted using a randomized block design. After 90 days of sowing, the growth performance of the plants and biomass accumulation was assessed. Accumulation of nutrients was estimated by analyzing the nutrient content using standard methods and multiplying it with dry biomass. Result: The result revealed that Crotolaria micans showed higher growth and biomass accumulation. C. micans accumulates higher N, P, K, Zn, Cu and Fe contents in the shoot and root biomass while A. indica accumulates higher Ca in the root biomass. We conclude that Crotolaria micans was the most promising leguminous weed species in terms of growth performance, biomass production and nutrient accumulation and has better potential to be utilized as a green manure crop.

印度东北部米佐拉姆邦一些豆科杂草作为潜在绿肥作物的评价

背景:本研究旨在评价3种丰富的豆科杂草——Crotolaria micans Link的生长性能、生物量产量和养分积累。、七香菜、甘露菜。在印度米佐拉姆邦发现，以评估它们作为绿肥作物的潜力。方法:采用随机区组设计进行田间试验。播种90 d后，评估植株的生长性能和生物量积累。利用标准方法分析养分含量，并与干生物量相乘，估算养分积累量。结果:结果表明，黄鼠狼有较高的生长和生物量积累。micans在茎部和根生物量中积累了较高的N、P、K、Zn、Cu和Fe含量，而A. indica在根生物量中积累了较高的Ca含量。综上所述，从生长性能、生物量生产和养分积累等方面来看，micans是最有潜力的豆科杂草品种，具有较好的绿肥利用潜力。
