Field studies were undertaken at Offinso in the Ashanti Region of Ghana during the 2015/2016 growing season to evaluate growth, root and dry matter yields of an improved cassava variety (Bankyehemaa) treated with poultry manure (PM), NPK 15-15-15 and NPK 23-10-10 fertilizers. The treatment structure was a 3 x 4 factorial, laid out in a Randomized Complete Block Design with three replications. Three levels of fertilizer (600 kg/ha NPK 15-15-15, 600 kg/ha NPK 23-10-10 and 2 t/ha PM) were applied at 6, 8, 10 and 12 weeks after planting. The parameters measured included plant height, fresh and dry shoot weights, number of stems per plant, stem girth, fresh and dry root yields and total dry matter yield. The data collected were subjected to analysis of variance using the Genstat Statistical package. Main effects of fertilizer type and time of fertilizer application on most of the parameters measured were not significant. However, the interaction effects of the two factors were significant in all the parameters measured. Vegetative growth of Bankyehemaa increased when mineral fertilizers were applied earlier than 12 weeks after planting. The highest fresh and dry shoot weights and the biggest stems were produced when NPK 15-15-15 fertilizer was applied at 6 weeks after planting. Plants treated with NPK 15-15-15 fertilizer at 10 weeks after planting were the tallest, while those treated with NPK 23-10-10 fertilizer at 8 weeks after planting produced the highest number of stems per plant. Application of poultry manure at 6 weeks after planting produced the highest fresh cassava root yield of 28.10 t/ha. The highest dry matter yield of 19.80 t/ha was obtained when poultry manure was applied at 12 weeks after planting.

Nursery experiment was conducted at Haru Agricultural Research Sub Center (HARSC) of Jimma Agricultural Research Center, Western Ethiopia, to investigate dry matter yield and its nutrient uptake of Arabica coffee seedlings under different lime and coffee husk compost rates and establish optimum combination of theseagricul tural inputs that produce seedlings with better dry matter yield for field planting. The experiment was laid out in a factorial experiment arranged in randomized complete block design with three replications. The treatments included four levels of lime (0, 1.6, 3.2 and 4.8 t ha-1) and coffee husk compost (0, 5, 10 and 15 t ha-1). Nutrient uptake and dry matter yield data of coffee seedlings were collected and subjected to analysis of variance using SAS package and treatment means were compared at 0.05 probability using Duncan’s Multiple Range Test. The results revealed that lime and coffee husk compost rates significantly (P< 0.01) affected NPK uptake and total dry matter yield of coffee seedlings. The highest NPK uptake and total dry matter yield of coffee seedling were obtained from the application of 15 t.ha-1 coffee husk compost and combined lime and coffee husk compost at the modest levels of 3.2 t.ha-1 lime and 10 t.ha-1 coffee husk compost with a nonsignificant variation. From the study, it can be concluded that application of 15 t.ha-1 coffeehusk compost or combining 10 t.ha-1 of coffee husk compost and 3.2 t.ha-1 of agricultural lime could be a promising alternative amendment for acid soil management and production of vigorous coffee seedlings with high nutrient uptake and high dry matter yield in HARSC areas.

A 3-yr study was conducted on Black and Gray Wooded soils at five different sites in the Aspen Parkland of Saskatchewan to determine the effect of spiking, burning, mowing, deep-banding (Trt) and applications of N, P, K and S liquid and granular fertilizers (Fert) on dry matter yield (DMY) and forage quality of primarily smooth bromegrass (Bromus inermis Leyss.) and alfalfa (Medicago sativa L.) pastures. Fertilizer application was a liquid form blended to provide 100 kg N ha–1, 45 kg P2O5 ha–1, 23 kg K2O ha–1 and 12 kg S ha–1 in 350 kg of fertilizer ha–1. The experimental design at each site was a randomized complete block in a split-plot arrangement. Main plots were spike, burn, mow, deep-band, deep-band liquid fertilizer and control. The split-plot treatment was granular fertilizer broadcast at 0 and 350 kg ha−1 (providing 100 kg N ha−1, 45 kg P2O5 ha−1, 23 kg K2O ha–1 and 12 kg S ha−1). All treatments were applied in the spring of 1994. Interaction effects of Trt × Yr and Fert × Yr were significant (P < 0.05) indicating a wide range of response to the rejuvenation methods among years. Spiking reduced (P < 0.05) DMY in year 1 at two sites. Deep-banding and mowing increased (P < 0.05) DMY at one site in year 3. Burning increased (P < 0.05) DMY in years 1 and 2 only at the Gray Wooded soil site. In year 1, liquid plus granular fertilizer (200 kg N ha–1) [deep-banded liquid fertilizer (DBLIQ at 100 kg N ha−1) + broadcast fertilizer (+F at 100 kg N ha−1] increased DMY at all sites by 84 to 185% over control plots. This effect carried over (P < 0.05) into year 2 at four sites but not the third and final year. The high rate of N (200 kg N ha−1) of the DBLIQ + F almost doubled (P < 0.05) crude protein content of year 1 forage, 170.3 g kg−1 compared with 96.4 g kg–1 for control. It was concluded that an application of broadcast or liquid fertilizer alone or combined with mechanical treatments will produce a significant effect on herbage yield and quality but only in the short term.

ABSTRACT This study investigated the residual effects of pig slurry (PS) applied to common carpet grass pasture (Axonopus affinis) for two years (September 2008-March 2010) on dry matter yield and forage-nitrogen uptake from October 2010-May 2011. A field experiment was conducted in a randomized complete block design with four replications. The treatments were 102, 204, 306, 408, and 510 m3 ha-1 pig slurry applied for two years; one mineral nitrogen rate (1,250 kg ha-1 ammonium nitrate) for two years; and no nitrogen fertilization (control). The pasture was cut at intervals of 48, 34, 43 and 69 days, which corresponded to 266, 300, 343, and 412 days after the last fertilizer application, respectively. Dry matter yield increased by 398 kg ha-1 for each 100 m3 of PS applied, the equivalent of 317 and 564 kg ha-1 for each 100 kg ha-1 of inorganic and organic N applied, respectively. The residual effect of PS on dry matter yield and forage-nitrogen uptake ranged from 11-45% and 8-40%, respectively, indicating a gradual release and availability of N in PS, which can help reduce the amounts of nitrogen applied to pasture.

The effects of five times of irrigation, two times of N-fertilizer application and four rates of N-fertilizer application on the seed yield, dry matter yield, N, P, NO3-N, Ca, Mg, and K content and K/(Ca+Mg) ratio of Altai wild ryegrass (Elymus angustus Trin.), were studied from 1974 to 1977. No clear-cut methods to maximize the seed yield on irrigated land were found. Highest dry matter yields were obtained from grass given three irrigations and 400 kg N/ha per year. Spring applications of N fertilizer resulted in forage with a higher N content than fall applications. The N content of the forage increased with increasing levels of N fertilizer, whereas the P content of the forage was reduced by N fertilizer applications. Toxic levels of nitrates can be expected from spring applications of 400 kg N/ha. This danger was reduced if N fertilizer was applied in the fall. The Ca, Mg and K content increased with increasing levels of N fertilizer. The K/(Ca+Mg) ratio indicated that there was little danger of grass tetany problems in animals fed fertilized Altai wild ryegrass.

SummaryRelations between yield, water use and pre-anthesis growth were analysed for cropsof barley grown for three seasons at several sites in northern Syria. The relations obtained were compared with those for other cereal crops grown in similar regions of Mediterranean climates.Phosphorus fertilizer application increased the rate of crop development from emergence to floral initiation and advanced anthesis by up to 11 days. Grain and total shoot dry-matter yields were increased by fertilizer (nitrogen + phosphorus) applications at all sites in all years, in most cases without increasing total evapotranspiration. The increased dry matter at anthesis was produced without having used a larger proportion of the total evapotranspiration in the whole season. Consequently, the ratio of grain yield to total above-ground dry-matter yield (harvest index) and kernel weight were also relatively stable between sites and years, despite some very low amounts of post-anthesis water use. Grain yield appeared to be largely determined by anthesis and there were strong linear relationships between grain yield or total dry-matter yield and number of kernels. Differences in water use efficiency of crops given fertilizer between sites and years were closely related to the differences in amounts of winter growth.Some responses differed from those predicted from models of growth, water use and yield developed in other regions with similar climates. It is concluded that agronomists and breeders should increase amounts of early growth thereby increasing grain and dry-matter yields. Future research emphasis should also be on the development of dynamic simulation models of pre-anthesis growth and water use.

An experiment was conducted twice concurrently at Vom in Plateau State Nigeria in 2011 to evaluate the effects of three animal based organic fertilizers and three rates of application on the growth, seed and herbage yields of Rhodes grass (Chloris gayana var. Callide). This study involved three types (poultry, rabbit and sheep dung) of animal fertilizer and three rates (0, 25 and 50 t ha-1) of application in a 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Animal fertilizers significantly (p < 0.05) increased growth, seed, fresh herbage and dry matter yields of Rhodes grass. Generally, fertilizers from poultry and rabbit were similar and better (p < 0.05) than that of sheep in the enhancement of the measured variables. At 6 weeks after fertilizer application (WAF), fresh herbage yield was in the range of 14.6 – 48.3 t ha-1 whereas dry matter yield ranged from 4.7 – 13.9 t ha-1 while seed yield was 1.8 – 2.3 t ha-1. At 12 WAF, rabbit fertilizer produced significantly higher values than sheep fertilizer by 21.2 % for sward height, 70.1 % for fresh herbage yield and 61.4 % for dry matter yield. The correlation coefficients among the measured variables were positive and highly significant. The highest correlation recorded (0.937**) was between fresh herbage and dry matter yields. The study indicated that application of either rabbit or poultry fertilizer can suitably enhance Rhodes grass growth for higher herbage and seed yields. The study also showed that 25 and 50 t ha-1 of animal fertilizers on Rhodes grass yielded similar results. With adequate fertilizer application, Rhodes grass can produce sufficient herbage to meet the nutritional requirement of several ruminant livestock. It is not economical to apply more than 25 t ha-1 of animal fertilizers to Rhodes grass if they contain more than 1.21 % of nitrogen.
