Soil health as influenced by FYM and nitrogen under rainfed saffron cultivation
Results revealed that with increase in the levels of the nitrogen fertilizer, the soil pH decreased significantly and minimum pH (6.12) was observed with nitrogen application of 90 kg ha-1. The interaction with farm yard manure also showed significant effect on the soil reaction. The soil pH was found minimum (6.05) when FYM and nitrogen were applied at 60 t ha-1 and 90 kg ha-1, respectively. The decrease over the control (6.33) was found to be 4.4%. The effect of nitrogen and FYM significantly increased the soil organic carbon (SOC) and the maximum SOC of 14.70 and 15.34 g kg-1 of soil were observed with highest application of Nitrogen and FYM. The maximum available nitrogen 315.6 and 348.8 kg ha-1 was found with the application of nitrogen at 90 kg ha-1 and FYM at 60 t ha-1, respectively. The increase over their respective controls (255.7 and 226.1 kg ha-1) was 23.4 and 53.3%. Similarly the phosphorus availability in the soil was also significantly improved by the application of nitrogen and FYM, the maximum available P of 54.5 and 74.9 kg ha-1 was observed with the higher application of treatments. The maximum available potassium of 480.73 and 543.06 kg ha-1 was observed with the application of nitrogen at 90 kg ha-1 and FYM at 60 t ha-1, respectively. The increase over their respective controls was 27.27 and 63.55%. The overall soil health was found sustained with the application of organics over inorganic application.
