Abstract:
A field experiment was conducted on “Validation of STCR Based Fertilizer Prescription on the Farmer’s Field” of Lanjoda village, District-Kondagaon (C.G.)” during Kharif season, 2020 with the three objectives; To test the validity of fertilizer prescription equation developed for Rajeshwari variety of rice. The fertilizer prescription equations previously developed for rice (variety-Rajeshwari) in STCR project as FN=5.00T-0.78SN-0.3ON, FP= 1.40T-2.78SP-0.27OP and FK-1.57T-0.10SK-0.09OK were validated on farmer’s field with rice variety Rajeshwari. The experimental field was laid out in randomized block design with three replications, consisting of seven treatments as control (N0 P0 K0), farmers practice (N80 P50 K30), GRD (N100 P60 K40), STCR based dose for TY 50 q ha-1 (N102 P28 K45), STCR based dose for TY 50 q ha-1 with FYM (N95 P24 K39 + 5 t ha-1 FYM), STCR based dose for TY 60 q ha-1 (N151 P42 K61) and STCR based dose for TY 60 q ha-1 with FYM (N145 P38 K55 + 5 t ha-1 FYM). The soil of experimental field belongs to the soil order of Vertisol having clayey in texture. The highest mean grain yield was recorded with treatment YT 60 q/ha without FYM (61.44 q/ha) and YT 60 q/ha with FYM (60.25 q/ha) which were statistically at par and significantly higher than rest of treatments. Treatments YT 50 q/ha with FYM, GRD, and YT 50q/ha without FYM gave grain yield as 50.24, 50.06 and 49.44 q/ha, respectively were significantly higher than farmers practice dose (41.32 q/ha) followed by control (24.20 q/ha). Significantly highest straw yield (73.37 q/ha) was recorded under treatment YT 60 q/ha followed by YT60 q/ha with FYM (70.45 q/ha), which were statistically at par and both the treatments gave significantly higher straw yield than other treatments. Lowest straw yield recorded in control plot.
