Genetic and Environmental Responses of Harvest Index and Other Agronomic Traits in Winter Wheat (Triticum Aestivum L.) and Spring Oats (Avena Sativa L.)
… agronomic traits, especially harvest index, total dry matter production, and growth rate, for improving grain yield. The effect of four nitrogen fertilizer treatments on harvest index, grain yield, grain protein percentage, grain protein yield, and total dry matter yield of wheat was …

Compatibility, Yield, and Quality of Matua Prairie Grass, Bromus willdenowii (Kunth), with Legumes
… no effect on percentage Matua prairie grass or total dry matter yield in 1998. However, in 1999 the ladino clover and red clover treatments increased (P<0.05) total dry matter yield, but also resulted in a substantial decrease (P<0.05) in percentage Matua prairie grass. Nitrogen application in …

Evaluation of Five Cycles of Selection for Canopy Photosynthesis in Corn
… is a primary mechanism which determines the total dry matter production and thus economic yield of a plant. Beginning in 1982, half-sib families of maize synthetic RSSSC were monitored for CO$\sb2$ exchange rate, (CER), a common indicator of photosynthesis. The objectives of the study were to …

Fermentation, digestibility and palatability of ensiled broiler litter and corn forage
… estimated to contribute 15, 30 and 45% of the total dry matter. For these, mixtures were mixed by hand in 2 kg amounts and packed into small polyethylene bags supported in cardboard food containers. For the large-bag study the treatments at reach maturity were: untreated; urea, 0.5%, wet basis; …

Regrowth analysis of alfalfa (Medicago sativa, L.) during three seasons in 1966
… date of cutting in each season. The rate and total dry matter produced was higher during spring and early summer seasons than in late summer. The higher L.A.I. during spring than for the other two seasons may be attributed to production of new leaves because of weevil and frost damage. The …

Plant to plant variation in harvest index in lentil (Lens culinaris L.) : A dissertation submitted in partial fulfilment of the requirements for the Diploma of Agricultural Science in the University of Canterbury New Zealand
… between 0.40 to 0.50. In autumn-sown lentils, total dry matter production per plant increased from 3.90 to 4.90 g/plant with increased irrigation. Spring-sown plants did not show any significant response to irrigation in dry matter production. Irrigation of the autumn-sown crop had a negative …

Effects of certain fertilizer and lime treatments on some chemical properties of Cecil sandy loam
An investigation of the pH, organic matter content, total nitrogen, and cation exchange properties of the soil of the l8-year-old rotation plots at Chatham, Virginia, was carried out. Individual soil samples were taken of each of the 36 sub-plots which compose the experiment. After the chemical …

The response of field bean (Vicia faba L.) to irrigation and sowing date
… sowings by about 55% due to both a greater dry matter production and a larger harvest index. Both total dry matter and grain yield were linearly dependent upon the sum of the rainfall and irrigation received by the crops during the main growth period. Penman's model described the response of …

Effects of panicle removal and nitrogen on yield of grain sorghum
… index = 0.5). Nitrogen application increased total dry matter, tillers, grain yield, and number of kernels in each variety except that Korwane was not responsive in kernel number. Nitrogen fertilization decreased kernel weight in two of the varieties but not Korwane. Kernel weight of Korwane …

Intake and Digestibility of Brown-Midrib Corn Silage by Lactating Dairy Cows
… fed a ration of silage and grain (60:40 ratio, dry matter basis) from week 2 through 8 of lactation. Lignin percentages for bm<sub>3</sub> and normal silages were 4.9 and 6.4. Cattle fed the bm<sub>3</sub> ration consumed 19% more total dry matter as percent of body weight than cows fed normal. …

Nitrogen fertilization, nitrogen and nicotine content of burley tobacco
… the period prior to topping 74 percent of the total dry matter, 80 percent of the total nitrogen and 34 percent of the total nicotine accumulated in the shoots. Applying 2/3 of the 75 pounds of nitrogen per acre 21 days after transplanting increased the yield over treatments in which nitrogen …

Lactase Activity in Steers Fed Large Amounts of Dried Whey
… dried whole whey (86% of concentrate mix, 60% of total dry matter intake) were fed to four Holstein steers in place of corn and soybean meal in the control diet to evaluate the extent and site of lactose digestion in the ruminant's digestive tract. Diets consisted of 70% of the dry matter as …

Validation of the aquacrop model for the irrigated african eggplant(solanum macrocarpon) at the UNZA field station
… through irrigation resulted in decrease in total dry matter and final fruit yield produced. Results showed significant differences (P<0.05) in fruit yield and harvest index (HI) as affected by water application rate. These results therefore suggest that irrigation water requirements of …

Effect of plant density on soybean seed yield and quality
… 4 x 1.8 m. Seed yield was strongly related to total dry matter at the start of seed fill, which in turn was a function of the amount of photosynthetically active radiation (PAR) intercepted by the canopy. A green area index (GAI) of 3.4-3.6 was required to attain canopy closure interception of …

Flavor effects on feed consumption and performance of dairy cattle in early lactation
… Starting eight days postpartum cows were fed a total mixed ration (TMR) twice daily. Four additives and a control (no additive) were examined in each trial with the most preferred, highest total dry matter (DM) intake, being dropped after 5, 4, 3 and 2 d feeding segments. Sweet (sucrose, 1.5% of …

Effects of hydroxy versus sulfate forms of trace minerals in milk replacer or starter on dairy calves through weaning
… and starter intakes were combined to calculate total intake. Blood was sampled at d 14, 28, and 56 immediately before feeding and 4 h post feeding. Blood plasma was used to evaluate concentrations of minerals, total protein, albumin, glucose, non-esterified fatty acids (NEFA), and urea nitrogen. …

From forest to pasture without weeds: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
Dry matter production, botanical composition and seedling size of a ryegrass/ subterranean clover pasture sown on 1 April out of Pinus radiata were measured over three harvest dates (28 July, 17 August, 7 September) in Darfield (43° B'S, 172° 8'E). Pasture was grown at 4 lime rates (0, 2.5, 5, 10 T …

The influence of ryegrass sowing rates and nitrogen fertiliser on white clover establishment : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
… assessed. There was no advantage in terms of dry matter production from sowing greater than 10 kg/ha. Total dry matter from at 10 kg/ha was 3600 kgDM/ha from 19/02/04 until 09/09/04. In September (203 DAS) there was no difference in ryegrass plant population numbers in the 10 and 20 kg/ha …
