Effect of Fym, Zn and Trichoderma spp. on content and uptake of N, P, K, Fe, Mn, Cu, Zn and Cd by spinach beet grown in Cd contaminated soil

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 1st, 2nd and 3rd, respectively. However, significantly lowest Cd content was found due to application of FYM @ 20 t ha-1 over F0 during 1st, 2nd and 3rd 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 2nd 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 2nd and 3rd cutting. While Cu and Cd content in leaves during 1st and 3rd 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 1st, 2nd and 3rd 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 1st, 2nd and 3rd cutting.
