This study assessed the dry matter yield, mineral and proximate composition of Panicum maximum Jacq var. Ntchisi planted with Lablab purpureus (Lablab), Centrosema pubescens (Centro), Aeschynomene histrix (A. histrix) and Stylosanthes guianensis (Stylo) in a 3 x 5 factorial experiment using Randomized Complete Block Design in early, mid and late rainy season. The dry matter yields (DMY) of panicum sown with Lablab (11.82 t/ha/yr) was significantly higher (P<0.05) than that observed for other mixtures. The least DMY of 9.46 t/ha/yr was observed for panicum in panicum/ A. histrix mixture. The yields recorded for Stylo and Lablab were highest in mid and late rainy seasons than in the early rain. Panicum sown with Lablab had the highest DM (37.71g/100g DM), Crude protein (CP) (11.36g/100g DM), ether extracts (7.20g/100g DM) and ash content (2.52g/100g DM). Among the legumes, Lablab had the highest CP (23.29 g/100g DM), crude fibre (10.61 g/100g DM) and ash content (3.96 g/100g DM). However, Centro was highest in ether extract (9.30g/100g DM). Panicum sown with Lablab had higher concentration of sodium (Na) and iron (Fe) while panicum planted with Stylo had highest concentration of phosphorus (P). The concentration of calcium (Ca) was similar (P>0.05) among the mixtures but differed (P<0.05) in the legumes. Stylo had the highest Ca concentration (0.72%) whereas highest P and Fe values were observed in Lablab. In conclusion, panicum harvested from panicum/lablab mixture had the highest DMY, CP, EE and ash content of grass in early, mid and late rainy season than the other mixtures.

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.

Randomized Block Design

The study aimed to evaluate the agronomic characteristics of elephant grass (Pennisetum purpureum Schum.) genotypes on energy production in the combustion form. A randomized block design with 3 repetitions was used. The treatments were arranged in subdivided plots scheme, considering as a plot the genotypes and as subplots, the harvest season. The agronomic characteristics plant height (H), leaf length (LL), leaf blade width (LBW), stem diameter (SD), tillers number (TN), stem percentage (SP), dry matter yield (DMY) were evaluated. The rainy season provided greater H to elephant grass genotypes with height above 3.5 m. The average SP obtained by the genotypes was 68.21% and 67.21% to the first and second year of cultivation, respectively, which gives the biomass good quality of burning. The rainy season provided greater DMY comparing to the dry season. In the first year of cultivation there were genotypes with annual dry matter yield (ADMY) above 50 ton ha-1 year-1, however, the non-maintenance of soil fertility promoted the reduction of 39.17% and 39.05% in the DMY and ADMY, respectively. Analyzing the agronomic characteristics, we conclude that the promising genotypes of elephant grass to produce energy in the form of direct combustion are CNPGL 91-25-1, Cubano Pinda, BRS Canará, Porto Rico and Mercker.

Shading (S), bioregulators (BR) and biostimulants (BS) techniques are alternatives that promote sprouting and production of grass. The objective was to evaluate the effect of S, BR and BSt on the growth and yield of Mombaza grass in Ecuador. A complete randomized block design, with split plot arrangement and three replications, was used, the main plot represented by condition S (S1: full solar exposure, S2: shade of trees) and secondary one by BR and BS application (A0: control; A1: minimum doses of BR, 250 mL.ha-1 Cytokin + 10 g.ha-1 New Gibb 10 %; A2: maximum doses of BR, 500 mL.ha-1 Cytokin + 20 g.ha-1 New Gibb 10 %; A3: commercial dose of BS Algamar, seaweed, 750 g.ha-1). Three cuts of grass were made, 35 days after staring experiment; in each one, tiller height (TH), number of tillersm-2 (NTM) and stemstiller-1 (NST), and dry matter yield (DMY) were evaluated. It is found effects (P<0.05) of S on the four variables in each cut; and application of BR and BS on TH in cuts 1, period of least precipitation. It is concluded that the grass cultivated in S1 increased the growth and DMY in cuts 1, 2 and 3 (0.180, 0.300 y 0.398 kg.m-2). NTM was stimulated with S2 and TH with the minimum dose of BR.

The effects of fertilizer-N application and cutting frequency on the herbage yield of Panicum maximum pasture were investigated in 2001 through 2004 in a sandy loam soil at Nsukka. The experiment was a 4r 4 factorial arrangement laid out in a randomized complete block design with three replications. Treatments comprised four levels of Nitrogen of 0, 150, 300, and 450 kg N ha' and four harvesting frequencies of 3-6-19- and 12-weekly intervals, resulting in süteen treatment combinations per block, Grass dry matter yield increased significantly (P < 0.05) from 7.799 to 10,993 kg ha' and from 5,715 to 14,220 kg ha' when the interval between cuts extended from 3 to 12 weeks at the first and fourth harvest years, respectively. Pasture plots cut at 3- or 6 weeks intervals exhibited much greater weed proportion than those cut at 9-, or 12-week interval. The total annual herbage dry matter yield increased significantly (P < 0.05) from 8.564 to 11,312 kg ha and from 6,814 to 10,268 in 2001 and 2004, respectively, when fertilizer N was increased from 0 to 450 kg N ha. A combination of 12-weekly interval of cut with 300 kg N ha gave a significantly higher forage grass herbage dry matter yield compared with the values got from 3- or 6-weekly interval combined with any N rate. Fertilizing at 300-450 kg N ha when combined with cutting at 9 to 12-weekly interval bet ween citts was more effective in suppressing growth and proportion of weeds.

Irrigation trials were conducted in the late dry season (March to June) with Lublab (Lablab purpureus) and Columbus grass (Sorghum almum) in the Sudan savanna of Nigeria. The objective of this study was to determine the dry matter yield (IDM/ha), crude protein (CP), calcium (Ca) and phosphorus(P) in dual-purpose lablab bean and Sorghum almum at 3 irrigation schedules (5, 7 and 10 days irrigation interval). The results obtained showed dry matter yield in lablab increased (P<0.05) and varied from 1.7 to 11.7 IDM/ha. Calcium and P concentrations differed significantly (P<0.05). Mean CP for the lablab was 15.57%. Dry matter yield obtained for Sorghum almum varied (P<0.05) from 11.07 to 19.6 tDM/ha. Concentration of CP and Ca rose and declined thereafter with a mean concentration of 9.86% for CP und 0.08% for Ca while P declined consistently (P<0.05). Intervals of irrigation days had a relationship (P<0.05) with DM/ha, Ca and P in lablab. The increasing trend in foruye yield with increased irrigation interval showed optimum irrigation interval was not attained. It is therefore recommended that longer irrigation intervals be tried to determine the optimum irrigation interval after which forage yield would be depressed due to moisture stress. From the results of the present study Sorghum almum and lablab would be grown successfully at a 10-day irrigation interval.

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.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.
