Abstract

Zinc (Zn) deficiency is one of the major global nutrition concerns, particularly in regions where diets are cereal dominant. About 50% of soils poor in zinc have resulted in zinc deficiency in cereal grains. Farmyard manure (FYM) with Zn application is the way to meet the Zn needs of crops and to raise the Zn content of grain that is ultimately consumed by people. Therefore, a pot experiment was conducted at the Department of Soil Science and Agricultural Chemistry of JNKVV, Jabalpur, in the Rabi season of 2020-2021 with three levels of FYM (0, 5.0, and 10 t ha-1) and three levels of zinc (0, 5 and 10 kg Zn ha-1) through ZnSO4.7H2O in a completely randomized design (CRD). Results revealed that the addition of 5 t FYM ha-1 + 10 kg Zn ha-1 produced significantly better results for the plant height compared to the control. The combined application of 10 t FYM ha-1 + 10 kg Zn ha-1 showed the highest SPAD (Soil Plant Analysis Development) meter reading at 21 DAS (Days after sowing), but it was the highest at the sole application of 10 t FYM ha-1 at 45 DAS. Significant enhancements in spike length (7.65 cm), weight and number of grains per spike (23.90), and DMP of 7.12 g pot-1 were recorded with the 5 kg Zn ha-1 sole application. However, the highest grain weight (2.50 g pot-1) was recorded with 5 t FYM ha-1 + 5 kg Zn ha-1, which was on par with 5 t FYM ha-1, 5 kg Zn ha-1, and 10 t FYM ha-1+10 kg Zn ha-1. The highest Zn content (48.95 mg kg-1) in wheat grain was recorded with 10 kg Zn ha-1, followed by 5 t FYM ha-1 + 10 kg Zn ha-1 (44.45 mg kg-1). The highest Zn uptake of 99.53 µg pot-1 by grain of wheat was recorded with 5 t FYM ha-1 + 5 kg Zn ha-1, which was significantly superior to all the treatments but on par with 5 kg Zn ha-1 (98.82 µg pot-1). Combined application of 5 t FYM ha-1 +10 kg Zn ha-1 maintain extractable zinc in soil as compared to control.
