Application and mechanism of action of Trichoderma spp. in repairing environment and promoting crop growth

Abstract

The field investigation was conducted at farmer field of dhamtari district during Rabi 2019 and Kharif 2020 to study the efficacy of Trichoderma spp. degradable microorganisms on paddy straw. in dhamtari district during kharif paddy is cultivated 136205 ha. and in Rabi 40475 ha total area 176680 ha. Indicates that total production of residue of paddy is almost 69187.88 ton for the total livestock of 321127. Thus the consumption of paddy residue per livestock stands at 0.22t/animal. Highest imbalance of livestock and consumption is noted in dhamtari district with zero consumption per animal. In modern times, powered machinery has replaced many farm jobs formerly carried out by manual labour or by working animals. The crop residues and stubble which left about a foot long. Ploughing this back into the soil was difficult, uprooting or otherwise cutting and collecting it was labour intensive and increasingly expensive. The farmers prefer easiest and cheapest method was to burn it in the field. It self burning of paddy stubble in dhamtari is a relatively big problem. Farmers themselves are doubly harmed, by the local air pollution caused, and by the loss of soil nutrients such as nitrogen, potassium, phosphorous and sulphur due to the burning. The field experiment was laid out in Completely Randomized Design (CRD) with a treatment replicated thrice. In the present investigation, freshly harvested paddy straw dried under sunlight in field that paddy straw treated with combination of 40kg FYM: 5kg Trichoderma spp/acre had significant influence in degrading paddy straw similarly, enhanced production of treated land.
