| Abstract:
Application of FYM had more pronounced effect on saffron yield as compared to in-organic fertilizers. FYM alone at different levels recorded the highest saffron yield (4.011 kg/ha), whereas impact with inorganic fertilizers was exhibited to the tune of 3.417 kg/ha (CLF). Application of FYM at 350 kg ha-1 in combination with N:P:K at 30:20:15 kg/ha recorded maximum saffron yield averaged over 3 years (4.350 kg/ha) showing an increase of above 91% over the control plots. For corm production application of FYM at 350 kg ha-1 in combination with Compound Liquid Fertilizer (12% N, 7% P2O5, K2O, Fe, Zn Chelates) at 7 g/1000 m recorded maximum corm yield/m2 (1047 g), followed by application of FYM at 350 kg ha-1 in combination with Urea spray at 46%. Maximum corm yield was associated with maximum percentage of flowering corms weighing above 5 g (>77%). An increase of 30% in corm production was recorded with application of vermicompost ranging from 300 to 350 kg/ha. However, application of 250 kg vermicompost in combination with recommended level of FYM and N:P:K recorded highest corm yield/m2 (980 g) showing an increase of 57.42% over control. Study suggests a beneficial effect of vermicompost in saffron and thus it can be effectively used as an alternative for application of FYM which presently is unavailable and if available is very costly. | |
