Abstract:
A pot culture experiment was conducted at Rajmohini Devi College of Agriculture Research Station, Ambikapur in Kharif season during 2018. The study was made about limiting plant nutrient based on crop response through nutrient omission technique in Alfisol of surajpur district of Chhattisgarh. For pot culture experiment rice crop variety MTU-1010 was taken as a test crop and further for field demonstration wheat crop was used in farmer field in order to have site specific nutrient management in the field. There were total 11 treatment with 3 replication under completely randomized design in pot culture experiment. It was found that there was significant reduction in straw and grain yield of rice with omission of N, P, K and Zn when compared with the treatment that received all the treatment i.e. SSNM. The test was conducted in order to check the limiting nutrient in farmer filed from where the soil sample were collected for pot culture experiment. The limited plant nutrient was corrected by application of as N - 120, P -35 (80 kg P₂O₅), K- 42 (60 kg K₂O), S – 30 and Zn 5 Kg. The percentage yield increase due to application of SSNM applied dose over farmer’s practice dose were 33.03-40%. This result conclude that application of N, P, S and Zn in Alfisol and should be applied as per the recommended dose in order to attain maximum crop production.
