Injection Treatment

In field trials in 1993-94 on sandy soils at 2 sites in the Netherlands, cattle slurry was applied by injection into slots 25 cm apart (standard injection) or 75 cm apart (banded injection). Subsequently, maize cv. Melody or Mandigo was sown at a row spacing of 75 cm parallel to the slots, either at random lateral positions in the standard injection treatment or 10 cm from the injection slots of the banded injection treatment. All treatments, including a control without slurry, were combined with 0 or 20-31 kg/ha of subsurface banded P starter fertilizer. Dry matter yields of silage maize were on average reduced by 8% when standard injection of slurry was not supplemented with P. However, the yield reduction was only 2% when slurry was banded.

The research was carried out in the Eastern Mediterranean Agricultural Research Institute-Hacı Ali location with 4 replications according to the randomized block trial design in 2013-2014. 13 public and 1 private sector maize variety were used as material in the trials. According to the results of the analysis, it was determined that the maize varieties examined showed statistically significant differences in plant properties, dry grass and silage quality. Average plant height, number of leaves, leaf ratio, stem diameter, number of cob, stem ratio, cob ratio and green grass yield were 249.9 cm, 12.97 plant/piece, 19.24%, 22.08 mm, 0.93 plant/unit, 38.40% and 4,251.57 kg/da respectively. According to the analysis, it was observed that the average crude protein content, ADF ratio, NDF ratio, crude ash content, digestible dry matter ratio, crude protein yield, dry matter rate, dry matter yield and hay yield were 8.80%, 34.91%, 59.7%, 7.2%, 61.7%, 993.9 kg/ha, 29.4%, 11,640 kg/ha 12,570 kg/ha in dry grass, respectively. For the silage of varieties, the average crude protein content, ADF ratio, NDF ratio, pH, digestible dry matter rate, dry matter ratio, crude protein yield and Fleig score were 8.22%, 29.27%, 50.48%, 3.57, 66.1%, 28.14%, 926 kg/ha and 118.35, respectively. Burak, Sasa 1 and Ada 334 genotypes performed better in terms of green yield per hectare (53,650, 50,290 and 45,630 kg/ha) and dry matter yield (14,710, 12,810 and 12,410 kg/ha). These varieties can be recommended to producers as silage maize varieties under second crop conditions in Çukurova region of Turkey.

Annual Water

The effect of spraying maize weekly with a 0.5 M concentration of Cd was studied in Hungary at two water supply levels. Cd reduced the size of the leaf area and the annual water loss. The intensity of evapotranspiration (mm water/unit leaf area) of the polluted crops grew. The higher net radiation of polluted maize resulted in an increase in sensible heat and a warmer canopy. The warmer the canopy, the higher the stress level of the contaminated crops was. While Cd caused a 28% significant decline in plant dry matter production in the rainfed plots, only a declining tendency amounting to a few percent was recorded in the ET treatment.Cd of atmospheric origin was only detected in the leaves; it was not accumulated in the grain. It was concluded from the results that the yield losses in grain maize grown on Cd-polluted areas could be mitigated by irrigation. The production of silage maize, however, is not recommended in regions affected by Cd pollution, especially in areas where irrigation is required, since supplementary water supplies promote the accumulation of Cd in the vegetative organs.

Few Data

Leafy hybrids represent a new direction in the breeding of silage maize. Not only does the increased number of leaves above the ear in these hybrids lead to an increase in dry matter production, but the large quantity of carbohydrates formed and stored in the leaves results in silage with better chemical quality. Many papers have been published abroad on this subject, but few data have been reported in Hungary.The present work aimed to examine the effect of genotype and year on six leafy and non-leafy silage maize hybrids over a period of four years (2002–2005), with special emphasis on the plant height, ear attachment height, leaf number, and fresh and dry matter yield.The results showed that the number of leaves above the ear was much higher for the two leafy hybrids (8.00 and 9.35) than the average of the other hybrids (5.56, averaged over the years). This trait was in close negative correlation (r 2 = −0.7346) with the ratio of ear attachment height to total plant height, a trait with strong genetic determination, little influenced by the year. In leafy hybrids the main ear was located far lower down, but the total plant height was similar to that of the other hybrids. The ratio of ear attachment height to plant height was 0.36 for the leafy hybrids, but ranged from 0.41 to 0.45 for the other hybrids (averaged over the years). In wetter years the hybrids were taller and had greater dry matter production per plant than in the dry year.

N2o Fluxes

Cattle slurry injection (INJ) has shown to be an efficient measure to reduce ammonia (NH3) losses from soils but it might also significantly increase nitrous oxide (N2O) emissions, which can dominate the total greenhouse gas (GHG) release in silage maize production (Zea mays L.). Nitrification inhibitors (NIs) are known for their potential to mitigate N2O. Therefore, we tested the effect of NIs added to cattle slurry before INJ on N2O fluxes from a Haplic Luvisol under silage maize in southwest Germany. We determined N2O fluxes at least weekly, with the closed chamber method over two full years. NIs differ in their chemical and physical behavior and we therefore tested a range of commercially available NIs: 3,4-dimethylpyrazole phosphate, 3,4-dimethylpyrazol succinic acid, a mixture of both, nitrapyrin, dicyandiamide, and 1,2,4 triazol and 3-methylpyrazol. Although not significant, INJ treatments with NI showed lower mean annual N2O emissions than the INJ treatment without NI in the 1st year. The emission reduction by NI of 46% in the 2nd year was statistically significant. In both years, we did not find any difference in N2O release, crop yield, or nitrogen removal between the different NI treatments. In the 1st year, which was extraordinary dry and warm, emission factors (EFs) for all INJ treatments were 4 to 8-fold higher than default EF from the IPCC. Even in the 2nd year, only three NI treatments reached EFs within the range provided by the IPCC. Direct N2O accounted for between 81 and 91% of the total GHG emission. Area- and yield-related GHG emission of the broadcast application with subsequent incorporation was in both years in the statistical class with lowest emission. In contrast, INJ with NIs showed similar GHG emissions in only one year, and consequently, incorporation was found to be the optimum management practice for livestock farmers in our study region.

In field experiments conducted on loamy luvic chernozem (170 m altitude, 48°34’ N 17°45’ E), the effects of undersowing time (5 days after maize was sown and into emerged stand) of lucerne, red clover and sainfoin on silage maize dry matter have been studied. The total dry matter yields were affected by time of undersowing of clover crops. The stands undersown after emergence of maize gave higher yields than former time of undersowing. The late time of undersowing improved conditions for growth of maize and formation of its yield. The number of maize plants had already insignificant effect on yields there. The dry matter weight, height, and number of maize plants and dry matter weight of weeds were main factors of formation of the total yield. The depressive effect of weeds on total yields was applied indirectly particularly through the decrease in the dry matter weight of maize plants. The path analysis in spite of the insignificant effect of clover crops undersown on total yields indicated some differences in the formation of yield. The number of maize plants reached the significant level of effect on yield only at stands with red clover undersown. On the contrary, the negative correlation of weeds dry matter weight with the number of maize plants reached level of significance in stands with lucerne undersown only.
