Workshop on crop residue management for environmental protection

under the joint aegis of Agriculture Department of Shri Ram College and Krishi Vigyan Kendra Chittoda, a two-day workshop on crop residue management for environmental protection

Today, under the joint aegis of Agriculture Department of Shri Ram College and Krishi Vigyan Kendra Chittoda, a two-day workshop on crop residue management for environmental protection was organized. The chief guest of this workshop was Dr. Prerna Mittal, Principal Shri Ram College, Muzaffarnagar. The key speaker of the program was Dr. Omvir Singh, Department President, Krishi Vigyan Kendra Chittora. On the second day of the two-day workshop, Dr. Omvir Singh, President, Krishi Vigyan Kendra, Chittora, in his address said that paddy is the second most produced grain in the world after maize. . He said that India is the second largest rice producing country in the world after China and about 60 percent of the world's population uses rice as their daily food, besides the use of paddy crop residues for paper making, mushroom production, It is also used for making compost, as animal feed and fuel. He said that crop residues are those parts of the plant (such as straw, stem, stalk, leaves and skin etc.), which are left in the field after harvesting and threshing. These residues take a long time to decompose, due to which the sowing of the next crop is delayed, so farmers prefer to burn these residues. China, India and the United States are at the top in crop residue burning. In India, it is mostly burnt in Punjab, Haryana and western Uttar Pradesh. At present, even in agriculturally developed states like Haryana and Punjab, only 10 percent farmers are managing crop residues. Giving information, he said that in our country 154.59 metric tonnes/year, paddy residue is produced. By burning it, 0.236 tonnes of nitrogen, 0.009 tonnes of phosphorus and 0.200 tonnes/year of potash are being lost. Due to lack of knowledge of techniques and some farmers, despite being ignorant, they are burning crop residues. Crop residue management is not done properly in our country. So this is becoming a very serious problem for us. It would also be correct to say that instead of using it in the form of organic matter in the soil, most of the part is destroyed by burning or used in other domestic works. According to a study, only 22 percent of the crop residue is used, the rest is burnt.

On burning of crop residues, beneficial nutrients stored in their root, stem and leaves are destroyed by burning. Burning paddy straw in the field results in the loss of almost all the amount of nitrogen present in the straw, about 25 percent of phosphorus, 20 percent of potassium, and 5 to 50 percent of sulfur. On this occasion Dr. P. S. Tiwari Assistant Professor Krishi Vigyan Kendra Chittauda said that by burning crop residue, gaseous pollutants like carbon monoxide, methane, nitrous oxide and hydrocarbons etc. He told that by burning one ton of straw, 3 kg. Particulate matter (PM), 60 kg. Carbon monoxide, 1,460 kg. Carbon dioxide, 199 kg ash and 2 kg. Sulfur dioxide is released. Therefore, due to these gases, the general air quality decreases. He pointed out that burning of paddy crop residue is an important source of especially aerosol particles such as coarse particulates (PM 10) and fine particulates (PM 2.5). It has been found in various studies that the fine particles released due to burning of agricultural residues easily enter the lungs, which causes heart problems. There is also a risk of fire. On this occasion Guest Speaker Krishi Vigyan Kendra Chittauda Dr. Surendra Singh while speaking in detail on the topic of the workshop said that instead of burning the crop residue, it can also be used for para mushroom cultivation. Guest speaker Krishi Vigyan on this occasion Kendra Chitauda Dr. JK Arya told that we have 50 to 60 percent biological efficiency of mushroom from paddy straw, that is, you can get more than 250 to 300 quintals of mushroom production from 500 to 600 quintals of paddy, which costs more than 200000 in the market. 2400000 can be up to Rs. Along with this, he gave lectures on natural farming.

On this occasion, Dr. Ashok Kumar, Director, Shri Ram College, told in his address that the use of Pusa decomposer for the management of paddy crop straw is such a small capsule made by the scientists of Indian Agricultural Research Institute, Pusa, which makes the crop residue beneficial. Converts agricultural waste into manure. The cost of one capsule is just Rs 4-5 and only 4 capsules are required to convert one acre of farm residue into useful manure. The burning of crop residues in the field, first of all, there is a decrease in soil moisture and increase in soil temperature, due to which the fertility of the field is reduced as well as the physical, chemical and biological condition of the soil is adversely affected.
Dr. Vineet Sharma, keeping in mind the environmental protection, said that farmers can earn more profit by not burning crop residues and using them as dry fodder by adding value to animal feed, which will greatly increase milk production and farmers. You can earn profit. In the second session of the second day of the workshop, poster competition and oral competition were organized. Poster competition was organized by the students of Faculty of Computer, Faculty of Bio-Science and Department of Agriculture. In which a total of 14 posters were shown. In the poster competition, Runa Singh (BSc Agriculture Science) got first position, Arjun Singh (BCA) got second position and Dhruv Vishwa Kumar (BCA) got third position. The same oral competition was organized by Faculty of Computer, Faculty of Bio-Science and Department of Agriculture, in which 15 students participated, out of which Chandni Kumari got first place, Rajnandani got second place and Lilavati got third place. Program Director Dr. Vikrant Kumar, Assistant Spokesperson, Department of Agricultural Sciences, keeping in mind the words of Dr. Ashok Kumar, Director of Shri Ram College, said that soon, awareness campaigns will be run from village to village by the Agriculture Department of Shri Ram College. To make aware about crop residue management and environmental protection.

Dr. Nishant Rathi, Dean of Computer Application Department, Shri Ram College, Dr. Nishant Rathi, Dr. Vineet Kumar Sharma, Dr. Pooja Tomar, Dr. Anjali, Dr. Jeetendra, Dr. Archana Negi, Abid Ahmed, Rajkumar, Sachin Sahu and Suraj Singh were present in this workshop. At the end of the program, Dr. Vikrant Kumar concluded the program by thanking all the scientists and all the teachers and all the students present in the program.
