Crop Sequence

Between 1957-58 and 1960-61, a crop sequence experiment with grain sorghum and peanuts with and without nitrogen fertilizer was carried out on Tippera clay loam at Katherine, N.T. Neither crop was influenced by the crop grown two years before it. Peanuts showed no response to preceding crop or to nitrogen fertilizer. Sorghum grain yields were 77 per cent higher after peanuts than after sorghum, and sorghum stubble yields 56 per cent higher. Nitrogen fertilizer increased sorghum grain and stubble yield when the crop followed sorghum, but not when the crop followed peanuts. Nitrogen content of sorghum grain was higher after peanuts than after sorghum, and was also increased slightly by nitrogen fertilizer. Nitrogen yield of sorghum grain was almost twice as high in crops following peanuts than in crops following sorghum. Nitrogen fertilizer increased nitrogen yield of sorghum grain when the crop followed sorghum, but not when the crop followed peanuts.

Nitrogen Percentage

The effect of nitrogen fertilizer applied at seeding on the nitrogen content of wheat grain was studied in 63 experiments during the six seasons 1956-1961. The overall effect of fertilizer was to increase grain nitrogen percentage, but there were situations where no change and even decreases in grain nitrogen percentage were found. The magnitude of the changes due to nitrogen fertilizer was small in relation to change brought about by climatic factors. Both the change in nitrogen content and nitrogen yield from applied fertilizer showed a relation to the nitrogen content of grain from unfertilized plants. Significant differences between varieties were found for nitrogen yield response but not for nitrogen content response.

This study investigated the effects of sorghum ensiled as whole grains with different dry matter concentrations on the apparent total tract digestibility (ATTD) of energy, crude nutrients and minerals in growing pigs. Whole grain sorghum batches with varying dry matter (DM) concentrations of 701 (S1), 738 (S2) and 809 g kg−1 (S3) due to different dates of harvest from the same arable plot, were stored in air-tight kegs (6 L) for 6 months to ensure complete fermentation. Subsequently, 9 crossbred barrows (34.6 ± 1.8 kg; (Duroc x Landrace) × Piétrain)) were used in a 3 × 3 Latin square feeding experiment. Diets were based on the respective sorghum grain silage and were supplemented with additional amino acids, minerals and vitamins to meet or exceed published feeding recommendations for growing pigs. The ATTD of gross energy, dry matter, organic matter, nitrogen-free extracts, and crude ash were higher in S1 compared to S3 treatments (p ≤ 0.05), while S2 was intermediate. Pigs fed S1 showed significantly higher ATTD of phosphorus (P) compared to all other groups while ATTD of calcium was unaffected irrespective of the feeding regime. In conclusion, growing pigs used whole grain sorghum fermented with a DM concentration of 701 g kg−1 (S1) most efficiently. In particular, the addition of inorganic P could have been reduced by 0.39 g kg−1 DM when using this silage compared to the variant with the highest DM value (809 g kg−1).

Interest in the use of popped sorghum in food products has resulted in a niche market for sorghum hybrids with high popping quality but little work has been done to assess the relative effects of field processing methods of grain on popping quality. This study evaluated the relative effects of harvest moisture and threshing methods on the popping quality of sorghum grain. A grain sorghum hybrid with good popping quality was produced during two different years in Texas wherein it was harvested at two moisture levels (low and high) and grain was removed from panicles using five different threshing methods (hand, rubber belt, metal brushes and two metal concave bar systems). Years, harvest moisture content and threshing method influenced all three popping quality measurements (popping efficacy, expansion ratio and flake size), but threshing method had an order of magnitude larger effect than either moisture level or year. While many of the interactions were significant, they did not influence the general trends observed. As such, the threshing methods with less direct impact force on the grain (hand and rubber belt) had higher popping quality than those samples threshed with greater impact force on the grain (metal-based systems). The popping quality differences between threshing system are likely due to a reduction in kernel integrity caused by the impacts to the kernel that occurred while threshing the grain. The results herein indicate that field processing of the grain, notably threshing method has significant impacts on the popping quality and should be taken into consideration when grain sorghum is harvested for popping purposes.

Research in Kansas from 1983 to 1986 evaluated early preplant (30 to 45 days) and late preplant (10 to 14 days) herbicide treatments for weed control before ridge-till planting in a soybean and sorghum rotation. Control of fall panicum and common lambsquarters at planting time averaged at least 95% for all early preplant and 92% for late preplant treatments. Where no preplant treatment was used, heavy weed growth in spring delayed soil dry-down, which resulted in poor ridge-till planting conditions and reduced plant stands, and ultimately reduced sorghum grain yields by 24% and soybean yields by 12%. Horsenettle population declined significantly, and honeyvine milkweed population increased. Smooth groundcherry populations fluctuated from year to year with no overall change.

Pretreatment Phase

Nitrogen uptake by Rhodes grass was a linear function of the quantity of 15NH4N03 applied for rates up to the equivalent of 400 lb N/ac, but the proportion of fertilizer nitrogen recovered in the plants fell significantly when the rate was increased to 800 lb N/ac. A nitrogen pretreatment equivalent to 200 lb N/ac had relatively little effect on the uptake of 15NH4N03 by the grass, despite the fact that it almost doubled the weight of roots in the pots when the 15NH4N03 was first applied. Over the range 0–400 lb N/ac, 84.1%% of added total nitrogen and 75.5% of added 15N was taken up by plants that received no nitrogen fertilizer during the pretreatment phase, and 80.3% of added total nitrogen and 71.9% of added 15N was taken up by plants that received a pretreatment of 200 lb N/ac. Fertilizer nitrogen was distributed between tops and roots in the ratio (averaged for the two pretreatments) of 5.2 : 1 for total nitrogen and 4.5 : 1 for 15N; these ratios were constant over the range 0–400 lb N/ac and were not significantly different.

Safflower, linseed, and wheat were grown under irrigation at Kimberley Research Station in the 1964 dry season following 6 and 18 month clean and weedy fallows. Four levels of nitrogen fertilizer, as ammonium sulphate and urea, were superimposed. Crop nitrogen yields were highest after 18 months clean fallow, and were highly correlated with the amount of nitrate-nitrogen that had accumulated in the soil profile during the preceding fallow period. For wheat, which was the most efficient user of mineral nitrogen, 160 lb nitrogen an acre as ammonium sulphate was required after 18 months weedy fallow to equal the crop nitrogen yield after 18 months clean fallow without nitrogen fertilizer. The mean crop nitrogen yield with urea was only 76.7 per cent of that with ammonium sulphate. The results indicate that the form, and possibly the distribution, of mineral nitrogen in the soil in the early stages of crop growth could be important factors determining the efficiency of nitrogen for optimum plant performance.
