Abstract:
An experiment was conducted to assess performance of direct seeded rice under the soil test crop response (STCR) based nutrients management. The study was undertaken during
Kharif season of 2016 at the soil science research farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur Madhya Pradesh, India. The field experiment was laid out in four replications and six treatments
viz., T

in Randomized Block Design. Yield attributing characters like panicles per plant, panicle length (cm), panicle weightplant
-1 (g), number of grains per panicle and test weight (g) were found higher in T
6 (1.45, 21.27, 19.81, 119.73 and 24.49, respectively) and increase to the tune of 17.88, 26.23, 29.73, 47 and 17.68%, respectively, over control. Similarly, seed and straw yield found maximum in T
6 with application of 157:125:70 kg N, P
2O
5 and K
2O with 5 t FYM ha
-1 (5725 and 7623 kg ha
-1, respectively). The targeted yield of T
6 (60 q + 5 t FYM ha
-1) could not be achieved and deviated by ± 4.58% negatively, whereas the targeted yield of T
5 (50 q + 5 t FYM ha
-1) was obtained comfortably. Such findings explicitly showed that the usage of STCR-based fertilizers coupled with FYM was greatly successful in achieving the higher yield.
