Abstract: An investigation entitled “Effect of FYM, Zn and Trichoderma spp. applications on growth, yield and cadmium uptake by spinach beet grown in Cd contaminated soil” was carried out during rabi 2016 at Department of Natural Resources Management, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari. The present pot trial consisting of 18 treatment combinations involving three levels of FYM (F₀: control, F₁: 10 t ha^-1 and F₂: 20 t ha^-1) and two levels of Trichoderma (T₀:- Control, T₁:- 2 kg ha^-1) and three levels of Zinc (Z₀: control, Z₁: 2.5 mg kg^-1 and Z₂: 5.0 mg kg^-1) was conducted in FCRD with three repetitions. The significantly highest content of N (3.20, 3.08 and 3.02 percent), P (0.23,0.23 and 0.16 percent) and K(3.86, 3.38 and 3.51 percent), Fe (526.79, 615.88, 313.10 ppm), Mn (53.61,50.10, 49.05 ppm), Cu (5.13, 6.08, 5.55 ppm) and Zn (15.48, 14.5, 15.78 ppm) were found due to application of FYM @ 20 t ha^-1 over F₁ and F₀ during 1^st, 2^nd and 3^rd, respectively. However, significantly lowest Cd content was found due to application of FYM @ 20 t ha^-1 over F₀ during 1^st, 2^nd and 3^rd cutting with magnitude in decrease by 9.06, 16.22 and 10.37 percent, respectively in leaves and 17.91 percent in root. However, N, P and K content significantly affected due to application of Trichoderma @ 2 kg ha^-1(T₁) over no application (T₀) except during 2^nd cutting in K content. Fe content was significantly affected due to application of Trichoderma @ 2 kg ha^-1(T₁) over no application (T₀) except Fe content during 2^nd and 3^rd cutting. While Cu and Cd content in leaves during 1^st and 3^rd cuttings and Cd content in root were significantly affected due to application of Trichoderma (2 kg ha^-1) over the control. The concentration of macro and micro nutrient were significantly higher with Z₂ treatment as compared to Z₁ and Z₀ treatment. However, macro and micro nutrients uptake by leaves significantly affected due to application of Trichoderma @ 2 kg ha^-1(T₁) over no application (T₀) during 1^st, 2^nd and 3^rd cutting. However, significantly highest N, P, K, Fe, Mn, Cu and Zn uptake by leaves were found due to application of Zinc @ 5 mg kg^-1(Z₂) over Z₁ and Z₀ with corresponding value of 0.302.0, 0.296, 0.275 g pot^-1; 0.0226, 0.0215, 0.0137 g pot^-1 and 0.394, 0.331, 0.341 g pot^-1; 5.13, 6.21 and 2.95 mg pot^-1; 0.53, 0. 51 and 0.48 mg pot^-1; 0.050, 0.059 and 0.052 mg pot^-1; and 0.1622, 0.1460 and 0.1489 mg pot^-1, respectively during 1^st, 2^nd and 3^rd cutting.
