Assessment of organic and inorganic fertilization on soil micronutrient cations and qualitative parameters of cauliflower

A field experiment was conducted to assess the organic and inorganic fertilization on soil micronutrient cations and qualitative parameters of cauliflower with nine treatments viz Control, 100 per cent FYM on N equivalent basis, 100 per cent N, 100 per cent NP, 100 per cent NK, 100 per cent PK, 100 per cent NPK, 100 per cent NPK + FYM and 150 per cent NPK + FYM replicated thrice in randomized block design in plot size of 3 m × 2.7 m on variety PSBK-1 during 2019-20 and 2020-21 at Dr YS Parmar University of Horticulture and Forestry, Solan, Himachal Pradesh. Highest available micronutrient cations (Fe, Zn and Mn) were recorded with application of FYM alone or in combination with NPK. Application of 100 or 150 per cent NPK along with FYM also recorded higher TSS and ascorbic acid content.
