A field study was conducted to evaluate the effect of boron (B) and zinc (Zn) fertilizer alone and in combination on yield, yield components and nutrient concentration in various plant parts. The treatments consisted of (a) untreated control (b) three levels of B (0, 1, 2 kg B per ha) and (c) three levels of Zn (0, 5, 10 kg Zn per ha). The basal dose of NPK at the rate of 150, 110, 60 kg per ha, respectively, was applied to all treatments except control. The treatments were arranged in randomized complete block design with four replications. Results showed that combined addition of 2.0 kg B and 5 kg Zn per ha produced significant impact on the grain yield and its components i.e., number of tillers m-2, spike length, number of grains spike-1and 1000-grain weight. The improvement in dry matter production and grain yield was 14.5% and 9.4%, over control, respectively, by the combined application of 2.0 kg B per ha and 5.0 kg Zn per ha. There was substantial increase in B concentration in grains i.e., 129.6% and 47.6% by individual addition of 2.0 kg B and 5.0 kg Zn per ha over control, respectively. The level of Zn content was raised from 15.2 to 37.4 mg per kg by application of 10.0 kg Zn per ha. Thus, substantial improvement in wheat productivity could be harvested with simultaneous increased concentration of Zn nutrient in grain for alleviation of syndrome caused due to Zn deficiency across rural and peri-urban communities.
