“…ies as either percentage of applied N recovered in the harvested portion, generally the grain, or as grain yield increase due to applied N. Other work in Nebraska (Pumphrey and Harris, 1956;Bigeriego et al, 1979), Kentucky (Miller et al,197 5), Ontario (Stevenson and Baldwin, 1969), and Minnesota (Nelson and Mac-Gregor, 1973;Moncrief et al, 1984) has shown no difference in grain yield between planting time and sidedress applications. Excessive delays or unusually dry conditions have reduced yields from late application (Jung et a1., 1972;Lewis et a1., 1983).…”

Corn Yield and Residual Soil Nitrate as Affected by Time and Rate of Nitrogen Application

1989

Efficient use of N fertilizer for corn (Zea mays L.) production is important for increasing economic return to the grower and for minimizing the potential impact on water quality. Time and rate of application are important management tools for improving N efficiency. This experiment was conducted for 3 yr on two nonirrigated southern Minnesota soils-a Mt. Carroll silt loam (fine-silty, mixed, mesic Mollie Hapludalf) and a Webster clay loam (fine-loamy, mixed, mesic Typic Haplaquoll)-to evaluate the effect of time and rate of N application on corn yield, N uptake, and residual soil N03-N. Nitrogen as (NH 4 hS0 4 was applied in a factorial arrangement of N rate (low and high) and time of application (at planting (PL), eight-leaf stage (SL), or split evenly between the two times (SP)). A zero N control and a very high N rate at PL were also included. Nitrogen rates were 75, 150, and 225 kg ha-• on the Mt. Carroll, and 100, 200, and 300 kg ha-• on the Webster. Grain and total dry matter (DM) yield, and plant uptake of N were increased by N application in five of six site years, in most cases up to the high N rate. Delayed N application (SL or SP vs. PL) resulted in either no effect or a slight decrease in DM and in variable effects on N uptake, depending on the year and location. Residual NO:;-N in the 1.5 m profile ranged from 150 to 400 kg ha-• for most treatments in the fall but was 50 to 70o/o lower the following spring. Residual NO:; in the fall was consistently increased by delayed application of the high N rate from the PL to SL stage, with most of the increase occurring in the upper 0.6 m of the profile. The decrease in residual NO:; from fall to spring, attributed in part to leaching beyond the sampled zone, minimized the potential carryover effect for the next year's production and indicated a potential for greater environmental impact where N application was delayed. Dry matter production, N uptake, and residual N03-N were affected by unusually dry periods in midsummer of all3 yr, especially at the Webster site.

“…;elle et al, 1981 ). Grain yields the following year were shown to be higher in response to greater amounts of residual N (Pumphrey and Harris, 1956;Olson et al, 1964;Herron et al, 1971;Rehm and Weise, 1975). Residual N potentially available for the following year's crop is also susceptible to loss by leaching or denitrification (Olson, 1979).…”

“…Most studies of N uptake patterns in maize have shown maximum accumulation rates occur near silking (Jones and Huston, 1914;Sayre, 1948;Jordan eta!., 1950;Hay eta!., 1953;Hanway, 1962; Mengel and Barber, 1974;Bigeriego et a!., 1979). Nitrogen application, when delayed too long, decreases yield and fertilizer N recovery (Pumphrey and Harris, 1956;IAEA, 1970;Jung eta!., 1972).…”

Improved fertilizer nitrogen (N) use efficiency in irrigated maize (Zea mays L.) often results from delaying application of moderate N rates until the crop is rapidly growing. The objective of this experiment was to determine how N application time, N rate, and planting date influenced the pattern of N and fertilizer−derived N (FN) accumulation in irrigated maize grown on a deep, productive silty clay loam soil (Typic Argiudoll, fine, montmorillonitic, mesic). A factorial combination of early and late planting, N application at planting, or at the 4−, 8− or 16−leaf growth stage, and two N rates (90 and 180 kg N ha−1 as 15N−depleted ammonium sulfate) were applied to the same plots in 1979–1980. Above−ground plant samples were taken at the 8−leaf, l2−leaf, silking, soft dough, and physiological maturity stages of growth. Average net rates of N and FN accumulation were calculated using a temperature index as the divisor. Rates of N and FN accumulation per plant were greatest between the 12−leaf and silking growth stages in 1979, except when N application was made at the 16−leaf stage where maximum accumulation rates occurred during early grain fill. Effects of N application time on N accumulation rates were more pronounced in 1980 and followed patterns similar to those in 1979. Substantial amounts of residual FN from 1979 accumulated in above−ground tissue in 1980. Residual FN uptake was apparently greater, in comparison to newly applied FN, in the heavily−fertilized or late−planted crop. Time of maximum N accumulation was delayed as time of N application was delayed. Grain yield was reduced by early N deprivation only when active N uptake ceased during early grain fill. Excessive N application minimized the effect of application time on final grain FN content. Delayed planting reduced FN recovery at both levels of N fertilization. Relative recovery of FN in maize grain was maximized by applying the low N rate late in vegetative growth, irrespective of planting date.

“…No phosphorus deficiencies existed on the sites of the first two seedings. Where Tripp soil has been heavily cropped, nitrogen has proved to be the major limiting plant nutrient ( 14,15). The nitrogen fertility status of the soil on which the first planting was made was much higher than that of the third planting because better nitrogen management practices had been used.…”

Synopsis Spanish, Evergreen, and Madrid sweetclovers differed little in dry matter production and nitrogen content in first‐ and early second‐year growth and exceeded common white only in first‐year growth. Hubam produced more forage, but contained no more nitrogen per acre. The biennial varieties did not differ appreciably in quantity of roots per acre. Nearly 90% of the roots were in the top foot. Nitrogen content of the roots decreased with increasing depth.
