“…Increases in grain yield were associated with linear increases in ear size, which were significant at P = 0.04, 0.09, and 0.07 in 1990, 1991, and 1992, respectively. Yield levels were twoto three-fold higher in this experiment than in previous studies that did not obtain yield increases from Cl fertilization of corn (Younts and Musgrave, 1958a;Teater et al, 1960;Parker et al, 1985;Schumacher and Fixen, 1989). Hybrid effects may also be a contributing factor to variation in corn responses to Cl as with wheat cultivars (Engel and Sanders, 1992).…”

“…Generally, they were not mfluenced by Cl rate (Table 4). Previous studies (Parker et al, 1985;Teater et al, 1960;Younts and Musgrave 1958a) also found no influence of Cl fertilization on the concentration of other elements in the ear-leaf. Although increasing rates of Cl application were accompanied by decreasing rates of OH-and soa-application, ear-leaf analysis did not indicate an influence of OH-and Soa-rate on plant nutrient status.…”

“…that have not shown significant responses to Cl (Younts and Musgrave, 1958a;Teater et al, 1960;Parker et al, 1985;Schumacher and Fixen, 1989). Chloride supply may, however, become limiting for the significantly higher yields that can be achieved by employing more intensive production practices.…”

Chloride nutrition of corn (Zea mays L.) was investigated to determine if Cl limits production in high‐yield environments. Experiments were conducted to evaluate the effects of Cl fertilization on a Freehold sandy loam (fine‐loamy, mixed, mesic Typic Hapludults) near Adelphia, NJ, using irrigation and intensive crop production practices. Corn was grown at 107 600 plant ha−1 with equidistant spacing. All plots received 454 kg K ha−1 using KOH, K2SO4, or KCl to establish five treatments: 0, 50, 100, 200, and 400 kg Cl ha−1. Positive responses of corn to added Cl were observed each year. In 1990, the Cl treatments averaged 1.1 Mg ha−1 more grain than the check yield of 11.3 Mg ha−1 (P = 0.08). In 1991, the check yield was 19.0 Mg ha−1 and the response to Cl was linear up to the 400 kg ha−1 rate, which yielded 20.5 Mg ha−1. In 1992, the Cl treatments averaged 0.5 Mg ha−1 more grain than the check yield of 14.5 Mg ha−1 (P = 0.07). Grain yields were positively correlated with increases in ear‐leaf Cl concentration. Increases in grain yield were associated with increased ear size. Chloride did not increase stover yield. A linear decrease in incidence of stalk rot with Cl rate was observed in 1992. Results suggest that, when produced in high‐yield environments, corn may respond to enhanced levels of Cl nutrition.

“…From these results it is concluded that the breakdown •Jf the stalk tissue which led to lodging was due to low potassium, since the addition of chloride as ammo:1ium chloride did not reduce the lodging. Chloride from the NH 4 Cl, while not measured directly by plant analysis, should have been readily taken up (8) and should have reduced lodging if chloride had been :~esponsible for reduced lodging. In previous years on this experimental site, lodging on the NP treatments was as high as 78%, whereas on those receiving NPK with potassium as KCl, it was 10% or less.…”

Ammonium chloride treatments were included on selected plots in a corn (Zea mays L.) field laboratory fertility study to determine whether or not reductions in lodging observed in previous years were due to chloride or potassium in the KCl treatments. Sixty‐four percent of the corn lodged in plots receiving no potassium and no chloride or chloride as NH4Cl, while lodging was only 16% with comparable KCl treatments. It is concluded that the reduction in lodging was due to potassium and not chloride.
