Bark and fruits of mahua (Madhuca indica) are spread uniformly in the field to destroy the wild onion weeds from the crop field. This wild onion weed germinates in wet type of soil and seen mostly in the monsoon season. Generally in 3-4 days, the wild onion weed starts germination after the onset of monsoon.
Crop: Onion
Crop Family: Amaryllidaceae
Crop Scientific Name: (Allium cepa)
Crop Vernacular Name: Dungali, Pyaaz, Kanda
Ingredients: Bark And Fruits Of Mahua In (Madhuca Indica)

"Soil improver, soil reclamation and erosion control Though not a legume, mahua develops mycorrhizal associations able to fix atmospheric N. Its extensive superficial root system binds the soil and limits erosion. In India, mahua was used in soil reclamation on hard lateritic soils. Fallen leaves on the soil provide organic matter but they do not break down as easily compared to teak leaves or Shorea robusta leaves (Bargali et al., 2015; Manna et al., 2004). Mahua seed cake is used as a fertilizer and to control root-knot nematode (Orwa et al., 2009; Yadav et al., 2005). "

"Consequence of Butea monosperma plantation on the nutrient cycling in a semiarid grazingland, Rajasthan, India - The soil moisture content also showed significant increase under Butea plantation than in the open grazingland. Of the total uptake, about 85% of nutrients, were transferred to above ground plant parts and very little was transferred to below ground parts. At both sites, the nutrients return to the soil through root was lower than that of litter disappearance. The study reveals that Butea trees can increase the nutrient content of understorey grasses by their rapid leaf turnover and decomposition of nutrient rich litter, which can result in significant increase in soil fertility."
