Decomposition of Paddy Straw Improved Soil Health in NICRA Village of Chatra District: A Review

Abstract

Front line demonstration was conducted during the years 2014-15, 2015-16, 2016-17 in NICRA adopted village Mardanpur in Arra Panchyat of Chatra Block in Chatra district of Jharkhand. The study was conducted to assess the effects of decomposition of paddy stable on productivity and profitability with soil health in local farming system as well as extra pollution of the technology to similar micro farming situation. The experiment consisting of two technology option TO-I: (Farmers Practice) Burning of paddy stable in field and collecting paddy stable for use as fuel of cooking and after onset of monsoon field prepare and transplant rice (Variety-Abhishek) with N80P60K30 TO-II: Decomposition of paddy stable 4.5q/ha after onset of monsoon in the month of June through rotovator and transplanted rice (Variety – Abhishek) with N60P45K23 in RBD design with 20 replication. The result showed that an average grain and straw yield of rice was 25q/ha and 74.80 q/ha in farmers practice in technology option TO-I where as technology option (TO-II) i.e. 28.33 q/ha and 98.84 q/ha respectively. Return for rupee spent was also higher i.e. 2.40 in TO-II as compared to farmers practice i.e. 1.85 (TO-I). It is due to (25%) reduction of chemical fertilizer in technology option (TO-II).
