“…Maize (Zea mays L.) is known to be very sensitive to Zn deficiency (Lindsay & Norvel, 1977). Under Zn deficiency stress, maize has shown white bands between the midrib and the margin of leaves (Singh, Natesan, Singh, & Usha, 2005), accompanied by an obvious decline in plant height (De Vasconcelos, Clístenes, & Fernando, 2011) and in dry matter production (Van Biljon, Wright, Fouche, & Botha, 2010). These symptoms are explained by the important physiological functions performed by Zn, which include protein synthesis and energy production (Hansch & Mendel, 2009).…”

Corn silage (Zea mays L.), grown on sandy soil, was severely affected by Zinc (Zn) deficiency stress. Mineral and organic Zn sources were required to prevent this deficiency. The objective of this study is to evaluate the effectiveness of dairy cattle (Bos taurus) slurry as an organic source of Zn in preventing Zn deficiency in corn silage grown on sandy soil. A field experiment was conducted and six rates of dairy cattle slurry were spread just before sowing: 0 or no slurry spread; 50; 100; 150; 200 and 300 t ha -1 . These slurry rates were compared to an adequate mineral Zn supply of 5 mg kg -1 applied to soil as (ZnSO 4 ·7H 2 O). Regression analysis has shown that slurry rates ranging between 50 and 60 t ha -1 had almost similar efficacy to the adequate Zn mineral supply. Both of them corrected Zn deficiency symptoms, enhanced plant growth and increased silage yield by 37.5%, compared to no Zn or slurry applications. A high slurry rate of 280 t ha -1 maximized silage yield but may pose a threat to the environment due to its high content of nitrogen (N). At the next cropping season, a sufficient DTPA residual Zn soil content of 0.9 mg kg -1 was recorded only with a high slurry rate (300 t ha -1 ).

“…In this regard, Lindsay and Norvel (1977) recommended a soil Zn content of 0.8 mg Kg -1 (DTPA extraction) as a critical level for corn production. Van Biljon et al (2010) established the amount of 3.8 mg Kg -1 (0.1 M HCl extraction) as a Zn optimum content on sandy soil for corn production. However, Zn can also be toxic when it's present in excess.…”

The objective of this study is to identify an adequate zinc (Zn) foliar spray concentration which corrects Zn deficiency without disrupting other plant mineral contents, enhances plant growth, and thereby corn silage yield when grown on sandy soil. A field experiment was conducted using five Zn foliar spray concentrations (w/v): 0.03%, 0.07%, 0.10%, 0.14% and 0.18%. Zn sulfate (ZnSO 4 . 7H 2 O) was used as a source of Zn. Zn foliar application was realized at two growth stages (6-7 and 9-10 leaf stages). A treatment without Zn foliar spray was maintained as control. The results showed a quadratic response of corn silage towards Zn foliar spray concentrations, in which 0.09% was the optimum value for overcoming Zn deficiency. Such level increased shoot Zn concentration at harvest from 15 mg kg -1 to 21.8 mg kg -1 , didn't decrease plant mineral content below critical levels, enhanced plant growth and raised silage yield by 49.4% compared to control. On the other hand, Zn foliar spray concentration up to 0.10% induced visible leaf damage, growth inhibition and a decrease of 26% in silage yield compared to Zn foliar applications at 0.09%.
