Abstract
The present investigation was carried out to study the effect of soil-test-based long-term fertilization on soil health and performance of rice crop in Vertisols of Central India. The experiment was started in 2007–08 consisting six treatments viz. Control (No fertilizers), General Recommended Dose (GRD) (12060-40), STCR based for 4 t ha−1 target, STCR based for 5.5 t ha−1 target, STCR based for 4 t ha−1 target + 5 t FYM ha−1 and STCR based for 5.5 t ha−1 target + 5t FYM ha−1 and with four replications. The crop cultivar of rice MR-219 was grown with different treatments and performance in terms of grain yield and straw yield were recorded at harvest of the crop. The soil chemical and biological properties were assessed by analyzing the soil samples after harvest of the crop collected from 0–15 cm depth. Experimental data was statistically analyzed by the standard analysis of variance technique appropriate to randomized block design to test the significance of treatment effects. The results of the study revealed that, balanced fertilization based on soil test recorded higher yield of rice over general recommended dose of fertilizers.
