Popis: Mulching is highly beneficial for resource conservation under rainfed conditions, but non–availability of organic biomass and easy availability of fertilizers and herbicides has led to a gradual discontinuation of this practice. Various vegetative materials, including some troublesome weedy perennials, are available locally, which can be recycled for enhanced soil moisture and nutrient conservation. A field experiment was conducted at Dehradun, India, from 2001–2004 to study the effect of mulching with kudzu (Peuraria hirsuta), wild sage (Lantana camara), and subabul (Leucaena leucocephala) applied at 30 and 60 days of growth of maize (Zea mays), maize harvest, and sowing of wheat (Triticum aestivum). Application of 10 t/ha (fresh biomass) added 1.6–2.3 t dry matter through Peuraria, 2.5–3.2 t through Lantana, and 2.9–3.9 t/ha through Leuceana, which contributed 47.7–60.9 kg N, 58.4–70.9 kg N, and 118.4–148.4 kg N/ha, respectively. All mulching materials were beneficial and improved productivity of maize ...
