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.

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.

Studies were carried out at Offinso in the Ashanti Region of Ghana to assess root quality of cassava grown with application of poultry manure and NPK 15-15-15 and NPK 23-10-10 fertilizers. The experimental design was a 2 x 6 factorial, arranged in a Randomized Complete Block Design (RCBD) with three replications. The treatments consisted of two cassava varieties in combination with five inorganic and/or organic fertilizer formulations and a control with no fertilizer. The parameters measured were starch content, poundability, nitrogen, phosphorus and potassium contents of cassava roots. The data collected were subjected to analysis of variance using the Genstat Statistical package. The results of the study indicated that Bankyehemaa produced higher starch content (29.86%) than the Nkabom variety. Fertilizer application increased starch content with the combined application of poultry manure and NPK 23-10-10 treatment recording the highest treatment effect (30.40%). Both the organic and inorganic fertilizers applied increased starch content of cassava roots. Poundability was not also affected by both variety and fertilizer application. However, roots treated with NPK 15-15-15 only and poultry manure alone were very poundable (3.0). Variety significantly affected only nitrogen and phosphorus contents of cassava roots. Bankyehemaa had higher content (0.72%) of nitrogen than Nkabom, while Nkabom recorded higher content (1.05%) of phosphorus than Bankyehemaa. Generally, application of fertilizer significantly affected root contents of nitrogen, phosphorus and potassium. However, potassium and phosphorus contents were reduced by the organic fertilizer (poultry manure). The NPK 15-15-15 treatment produced higher potassium (9.37%) and phosphorus (1.36%) contents of roots than the other treatments. The highest nitrogen content of roots (0.78%) was observed in the combined application of poultry manure and NPK 23-10-10 treatment.

AbstractThis study aimed at determining shoot and root characteristics of cassava as affected by root yield and the influence of soil moisture on vegetative growth and yield. Thirty cassava genotypes were evaluated for morphological and physiological characterization in three locations in Nigeria: Ibadan, Mokwa and Zaria. Randomized complete block design was used with four replicates. Studies on the pasting properties of the genotypes were also carried out. Data were collected on plant height, stem girth, stay-green ability, garri and fresh root weight. Genotypes differed significantly (P < 0.05) across and within locations for shoot and root characteristics. Across locations, genotype 011663 had the highest plant height (132.4 cm); 30572 had the largest stem girth (8.6 cm); and 010040 was the best stay-green (2.2). Genotype 011086 had the highest number of roots per plot (95.7), 950289 had the highest fresh root yield (24.3 t/ha), and 990554 had the highest percentage of dry matter (35.2). Trends in root yields across locations were Ibadan (28.9 t/ha), Mokwa (20.3 t/ha), and Zaria (8 t/ha). Five genotypes IITA-TMS-IBA950289, 010034, 990554, 011807, and 980581 had negligible interactions with the environment and so have broad adaptation and are considered stable; and two clones 011807 and 950166 were found to be the best for pasting properties. Breeding strategies that consider root size, total root number, harvest index, dry matter, with applications for household foods and industrial uses, will be an effective and efficient way to select genotypes for high yield.

ABSTRACT The elephant-grass undergoes successive cutting and periodical evaluations that it possible to identify clones with high stability for dry matter production, which can be used for energy production. The present study was carried out to evaluate stability dry matter yield for different parametric and non-parametric methods in elephant grass genotypes for biomass production undergoes successive cutting in the agroclimatic conditions of the Norte Fluminense (RJ, Brazil). The variable measured in the 40 genotypes was dry matter yield (DMY) at 2009, 2010 and 2011 in a field study designed as randomized block design with two replicates. Each sample was grown in different environment condition. The stability methods tested were the Yates and Cochran’s, Plaisted and Peterson’s, Wricke’s ecovalence, Annicchiarico’s, Lin and Binns’ and Kang and Phan’s. Results indicated that cutting (E) and genotypes (G) influenced significantly on the performance of dry matter yield. The non-parametric stability methods were effective for the evaluation of stability in dry matter yield. Genotypes Mercker, Pinda-México, Mercker 86-México, Guaçu/IZ, Mercker Pinda, P-241-Piracicaba and Cubano Pinda were stable stability dry matter yield. Hence, there are genotypes may be exploited in future breeding programmes in order to improve productivity of upland elephant grass over environment.

A field experiment was conducted during two seasons 2018/2019 and 2019/2020 at Homs Agriculture Research Center, General Commission for Scientific Agriculture Researches (GCSAR), Syria, to study the effect of nitrogen fertilization rates and foliar application of boron on root yield and quality and dry matter yield of fodder beet. Results showed that the effect of nitrogen fertilization was significant (p≤0.001) for all studied traits except brix%. The effects were significant positive on root, shoot and biological yields, sucrose percentage, root, shoot and total dry matter yields. On the other hand the effect of boron spraying was presented for each season separately, because the differences of boron treatments were significant for all parameters except brix% at each season, and HI at the two seasons, while the differences of years were significant for all parameters except for HI. the highest yield and yield components were achieved by adding 300 kg N/ha with the addition of boron under Homs governorate conditions.

Field experiment was carried out during the spring and fall seasons of 2019 at the Abu Ghraib Research Station of the Agricultural Research Office/ Ministry of Agriculture, was aimed to investigate the effect of plant growth inhibitors on growth and yield of several sorghum varieties .Randomized Complete Block Design within split plot arrangement with three replications was used. The main plot consists of three growth inhibitors (Cycocel, Ethiphon, and Mebiquat), which were added at stages six and eight leaf stage, in addition to the control treatment (distilled water only), the sub plot was included three cultivars (Mabrouk, Buhooth 70 and Giza 113). The results showed in both seasons significant interaction between cultivars and growth inhibitors in most of the studied traits. The plants of the variety Giza 113 sprayed with Ethiphon recorded the lowest period of reaching physiological maturity, the highest average dry matter yield, and the highest weight of 1000 grains (89.00 days, 17.32 ton ha-1, and 39.33 gm) respectively. The same variety recorded the highest content of chlorophyll in the leaves and the highest grain yield due to the effect of Mebiquat (49.50 spad, 3.93 ton ha-1. The cultivar Buhooth 70 with the effect of Cycocel achieved the highest average of dry matter yield of 33.27 ton ha-1.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

<p>Objetivou-se com o presente trabalho avaliar as características morfométricas e de rendimento da palma forrageira 'Gigante' submetida a diferentes tipos de adubação orgânica, química e organomineral e configurações de plantio<em>. </em>O experimento foi instalado em LATOSSOLO Vermelho-Amarelo distrófico, num delineamento em blocos casualizados, em esquema de parcelas subdivididas, com três repetições. As parcelas constituídas por duas configurações de plantio: 1) 24.0000 plantas ha<sup>-1</sup>, dispostas em fileira tripla, no espaçamento 3,00 x 1,00 x 0,25 m; 2) 26.666 plantas ha<sup>-1</sup>, dispostas em fileira quádrupla, no espaçamento 3,00 x 1,00 x 0,25 m; as subparcelas compostas por 12 tipos de adubação orgânica, química e organomineral. Aos 650 DAP mensuraram-se altura da planta, número, comprimento, largura e índice de área de cladódios, produção de matéria verde e seca e teor de matéria seca. As características morfométricas, o teor de matéria seca e a produção de massa verde e matéria seca foram influenciadas pelas adubações (P&lt;0,05), independentemente da configuração utilizada. Das características morfométricas apenas a largura e área do cladódio não foram influenciadas pelas adubações.

The experiment was installed in a dystrophic Red-Yellow LATOSOL (Oxisol), in a randomized block design, in a split plot design parcel, with three replications. The plots consist of two plant configurations: 1) 24.0000 pl ha<sup>-1</sup>, arranged in triple row, spaced 3.00 x 1.00 x 0.25 m; 2) 26,666 pl ha<sup>-1</sup>, arranged in quadruple row, spaced 3.00 x 1.00 x 0.25 m. The subplots are composed of types of organic, chemical, and organic mineral fertilizers. On the 650th DAP were measured the plant height, number, length, width, cladode area index, fresh and dry matter yield and dry matter content. Morphometric characteristics, the dry matter content and the green mass and dry matter production were influenced by fertilization (P &lt;0.05), regardless the configuration. From the morphometric features, only the width and cladode area were not affected by fertilization. The absence of fertilization or just 30 Mg ha<sup>-1</sup> yr<sup>-1</sup> of cattle manure is not enough to achieve satisfactory results with 'Gigante' forage cactus.</p>

The experiment was conducted at screen house of Centre for Dry land Agriculture, Bayero University Kano, in the year 2016. The objective of the study was to determine the effects of poultry manure and nitrogen rates from battery cage and deep litter systems on dry matter yield, morphological characteristics and forage quality of Columbus grass (Sorghum almum). Sorghum almum seeds were sown in 32 plastic containers (dimensions 26 cm height, 28 cm top width and 20cm base width) perforated at the bottom containing 12 kg mixture of sandy and loamy soil in ratio of 1:3. The treatments consisted of poultry manure from two production systems (Battery cage and Deep litter) and nitrogen rates (50, 60, 70 and 80 kgN/ha) in a 2x4 factorial combined in a completely randomized design. Parameters measured were dry matter yield, number of tillers and stem diameter at the late boot stage of Sorghum almum, in addition, forage quality parameters (CP, ADF NDF, digestible dry matter (DDM) dry matter intake as a percentage of body weight (DMI) and relative feud value (RFV)) were also evaluated. The results revealed no significant (p>0.05) difference between battery cage and deep litter fertilized Sorghum almum but deep litter fertilized Sorghum almum had numerically higher dry matter yield (5062.30 kg/ha) than battery cage (4400.40 kg/ha) Number of tillers and stem diameter were found to be significantly greater (p<0.05) in Deep litter (2.56 and5.70mm respectively) compared to Battery cage (1.13 and 5.08mm respectively. Both dry matter yield and stem diameter of Sorghum almum were significantly (p<0.05) highest at 80 kg N/ha. Crude protein was observed to be significant (P<0.05) in Sorghum almum fertilized with poultry manure from deep liter (11.35%) compared with buttery cage (10.05 %). The CP value was observed to increase with increased nitrogen rate with the highest value recorded at 80 kg N/ha (1.71%). Dry matter intake (us a percentage of body weight) was equally greater (p<0.05) in Sorghum album fertilized with deep litter (2.63%) compared to battery cage (2.49%). The value for NDF was significantly higher in sorghum almum fertilized with battery cage, while that of ADF was greater in deep litter it can be concluded that, Sorghum almum fertilized with manure from deep litter system produced better yield and nutritive value.

Farmers use Inorganic Fertilizers (IF) to improve kenaf yield in Nigeria. However, the detrimental effects of mineral fertilizers and its high cost calls for the use of organic fertilizers that are locally available and environment friendly. Combination of Organic Fertiliser (OF) with IF may reduce the bulkiness of OF while harnessing the benefit of both for higher yields. Field trials were conducted at Ibadan and Ilora in 2013 and 2014 to investigate the effects of combined fertilizers on the growth and yield of kenaf. Organic and IF (NPK 20:10:10) fertilizers as: (i) 160 kg ha-1 (sole organic), (ii) 100 kg ha-1 (sole IFl), (iii) Organic and IF at 50:50 ratio and (iv) control (no fertilizer). The experiment was laid out in Randomized Complete block design (RCBD) and replicated three times. Results showed that plant height (220.17 cm, 216.80 cm) and stem diameter (2.27 cm, 1.16 cm). Bast fiber (2.27 t/ha, 2.27 t/ha) and seed yield (1.69 t/ha, 1.78 t/ha) in Ibadan and Ilora respectively were significantly higher in plots with combined fertilizer. Combined fertilizers had the highest fiber and seed yield above sole application and control (no fertilizer application). Hence it is recommended for kenaf cultivation in Southwest Nigeria.
