The quality and palatibility of silage and hay complete ration based on organic primer garbage in peranakan etawah (PE) poadABSTRACT. This research was conducted to study the quality and palatability of silage and hay complete ration based on organic primer garbage in nine heads of Peranakan Etawah (PE) Goat. The quality of silage and hay was evaluated By measuring pH, total number of lactic acid Bacteria (LAB), palatability, dry matter (DM) and organic matter (OM) aroma and color of silage. Nine heads of peranakan etawah were grouped based on their lactation periode and randomly assigned to one of tree dietary treatments. The treatments were (1) Control rations; (2) silage complete ration (SRK); and (3) Hay complete ration (HRK). The results indicated that the silage had PH 4.15 and total number of LAB was 2.4 x 10 cfu/g of silage. Dry matter and organic matter digestibility of SRK were better than those of HRK. The palatability of SRK was higher than HRK but less than control. Storage of SRK for did not change dry matter and organic matter content. Organoleptic analysis indicated that texture and color of HRK were changed at after storage, while SRK was still constant. It is concluded that silage composed of organic primer garbage has high quality in terms of physical, chemical and microbial characteristics, prolong storage.

Steers of 252 kg initial mean liveweight were fed 0.44 kg of hay dry matter (DM)/head day-1 plus five rates of whole oats, crushed wheat or whole wheat, with the crushed wheat rations providing 0.7 to 1.3 times the estimated energy for maintenance. All-grain rations at these energy levels had been attempted, but resulted in digestive upset, and were abandoned. The results obtained, listed in the order of the above grains, were : 1 ) grain in ration to maintain liveweight: 1.31, 1.41 and 1.85 kg DMIhead day-1 ; 2) additional grain for each 10 kg improvement in liveweight over I2 weeks: 434,466 and 61 3 g DMIhead day-1 ; 3) mean digestible organic matter content (DOM) of rations, tested at the highest and lowest rates of grain : 69.4, 84.5 and 68.3%. The DOM of the oat rations declined by 8.1 units from the lowest to highest rate of grain. The relative liveweight change on oats could not be explained by the DOMs. Nevertheless, the results suggest, for similar conditions to those applying in our experiment, that: 1) whole oats may be at least as good a feed as crushed wheat, and both will be much better than whole wheat; 2) the feed requirement for maintenance may be about 20% less than standard recommendations; 3) even a little hay in the ration, compared with grain only, may greatly reduce the likelihood of digestive upset

This study evaluated silages made with varying proportions of viticulture by-products (VC) and starch extraction from cassava (CSE). It attempted to determine the effects of these proportions on the microbial population, fermentative losses, and chemical composition. The treatments were specified as the proportions of VC in the silage (0 g/kg, 250 g/kg, 500 g/kg, 750 g/kg, and 1000 g/kg). Silages were  evaluated before (0) and after 1, 3, 7, 15, 30, and 60 days of ensiling. The experimental design was completely randomized with five  treatments, six storage times and four replications. The increased level of VC in the silage enhanced its dry matter content, ammonia  nitrogen (NH3-N), and buffering capacity, and reduced organic matter content. Fifteen days after ensiling, additional VC increased the concentration of soluble carbohydrates. The increased level of VC decreased the count of Clostridium spp. and lactic acid bacteria (LAB). The incidence of yeasts and enterobacteria was low in all treatments at all time points. Over time, losses as effluent and gases increased. Use of increasing proportions from VC in silage made with CSE increased the contents of dry matter and soluble carbohydrates and  reduced the fermentative losses of the silage. The increased amount of VC also favoured pH reduction and reduced the proliferation of undesirable yeasts, while increasing the population of LAB.

Canada's western prairies, lying within the confines of the provinces of Manitoba, Saskatchewan and Alberta, are generally recognised as comprising one of the largest and most important agricultural areas on the American continent. The immense acreage of their arable lands, the great depth and high fertility of their soils and the unexcelled quality of their wheat, have made them widely and favourably known throughout the civilised world. As yet but sparsely settled they will for many years offer a large and attractive field for agricultural occupation and development.

Twenty grass populations were evaluated for dry matter yield, N content, P content, organic matter content, organic matter digestibility and winterhardiness. Of these populations, Agropyron intermedium was most suitable for a hay crop on a well-drained irrigated soil. Agropyron trichophorum, Bromus inermis, and Phalaris arundinacea were lower-yielding alternatives that had a satisfactory N content and good digestibility. Elymus angustus shows promise as an irrigated hay crop and should be evaluated further. The usefulness of the following populations was limited by one or more of these factors: low yield (Y), low N content (N), low digestibility (D) and lack of winterhardiness (W): Dactylis glomerata ’Kay’ (Y,N,D), Dactylis glomerata ’Chinook’ (Y,N,W), Elymus sibiricus (Y), Festuca arundinacea ’Kenmont’ (Y,N,W), Festuca elatior ’Trader’ (Y,N), Phleum pratense (Y,N,D), Poa ampla ’Sherman’ (N,D), Poa bulbosa cv. P4874 (Y,N,D), and Poa pratensis (Y,N,D).

Nitrogen (N) plays an important role in agricultural production. This study was designed to evaluate the presence of cultivable N cycle-associated microorganisms (nitrogen-fixing bacteria—NFB, proteolytic bacteria—PR, ammonifiers—AMO, ammonium-oxidizing bacteria—AOB, nitrite-oxidizing bacteria—NOB, and denitrifiers—DEN), and their relationship with physical-chemical and agronomic soil descriptors, inSolanum phurejarhizospheric soil samples, from traditional and organic crop management farms. A cluster analysis with the physical and chemical properties of soil, allowed to identify the organic matter content as an important factor that determines the outcome of that grouping. Significant differences () between farms were found in the abundance of this groups, but correlation analysis showed that proteolytic and nitrogen fixing bacteria were the main nitrogen associated functional groups affected by soils' physical-chemical characteristics. The amount of ammonia available is affected by the agricultural management strategy, which consequently affects the NFB abundance. Finally the results showed that PR, protease activity and soil properties related with organic matter transformation has a positive relationship with productivity, which given the high organic matter content of the Andean soils being studied, we conclude that nitrogen mineralization process has an important role in the nitrogen cycle and its bioavailability in this ecosystem.

Due to its importance for organic agriculture, one of the most important agricultural production systems, various sources have been proposed to increase soil organic matter content. Vermicompost is one of those sources known as the resistant last form of farmyard manure which is degraded by earthworms. Soil organic matter or humus and their compounds are nutrient sources that increase physical, chemical and biological quality of soil. Humus and humus compounds improve soil physical, chemical and biological quality parameters increasing rhizosphere aeration and water holding capacity, rehabilitating soil structure, providing plant nutrients and constituting natural media for microorganisms with their regulative effects on soil reactions. In this study, the effects of vermicompost on yield and some growth parameters of lettuce were investigated. For this purpose, a random block designed experiment with 5 different applications was conducted in 3 replicates. The applications were control, vermicompost applications of 100 kg, 200 kg and 300 kg per decare and conventional fertilization. According to the results obtained, yield and growth parameters were improved by vermicompost application when compared to control and conventional fertilization. As a result of this study, it was concluded that 300 kg vermicompost/da is a promising application in lettuce production for optimal yield and soil improvement.

A glasshouse experiment was conducted to study the effect of temporary flooding on the growth and development of cotton (Gossypium hirsutum L. cv. Deltapine 61) and the recovery of nitrogen applied as urea fertiliser in two black earths differing in organic matter content, with three water treatments. Two floodings were applied, at 15 days after planting and at 45 days.Plant dry weight and growth characteristics of the cotton plant such as height, number of leaves, leaf area and fruiting points were greatly reduced by the flooding treatments. The cotton plants were more affected by the first than the second flooding. A greater depression in the various growth characteristics was found in the high organic matter soil than the low organic matter soil. The soils behaved differently in their interaction with the water treatments. With the control water treatment, cotton grown on the high organic matter soil produced more dry matter and assimilated more nitrogen but had a lower nitrogen concentration and apparent recovery of urea nitrogen than did cotton grown on the low organic matter soil. For the flooding treatments the low organic matter soil produced more dry matter and assimilated more nitrogen, but had a lower nitrogen concentration and a higher apparent recovery of urea nitrogen than did cotton grown on the high organic matter soil.The lower apparent recovery of urea nitrogen in the high organic matter soil during temporary flooding appears due mainly to higher loss of nitrogen by denitrification, although other mechanisms may be significant. The wider implications of the results in terms of field practice with irrigated cotton are discussed.

Study on the data of forage quality was conducted to determine the quality of napier grass forage with different growth and morfological type. In Indonesia, there are two types of napier grass, namely the tall and short type. The data used in this study were of proximate and van soest analysis of tall-type napier grass forage Pennisetum purpureum Schum and short-type napier grass, cultivar Mott dwarf, which were obtained from the Bekasi Feed Quality and Certification Center and data obtained from journals. The results of the study showed that dry matter content of short-type napier grass was higher than those of tall-type napier grass (23% vs 20%), while fiber fractions such as crude fiber, NDF and ADF of short-type napier grass were lower than those of tall-type napier grass 32% vs 29%, 70% vs 65%, 43% vs 39%, respectively. It is therefore relative forage quality (RFQ) of short-type napier grass was higher than those of tall-type napier grass (68 vs 57). It is concluded that related to dry matter and fiber fraction value, the quality of short-type napier grass (cv. Mott) is better than those of tall-type napier grass. Key words: cultivar Mott, Pennisetum purpureum, relative forage quality (RFQ), short-type napier grass, tall-type napier grass

SUMMARYThe K balance, the difference between K added as fertilizer or farmyard manure (FYM) and K removed by the crops, was calculated for soils from the Classical and Ley-Arable experiments at Rothamsted and for the Woburn Ley-Arable experiment, for the duration of each experiment. Linear regressions on K balance accounted for 78% of the variation in exchangeable K (Ke) and for 83% in K uptake by ryegrass (KP) in the Classical experiments, for 56 and60% respectively in the Ley-Arable experiments at Rothamsted, and for 39 and 6% in the Woburn Ley-Arable experiment.Regressions of Ke and Kp on K balance suggested that, in the Rothamsted Ley-Arable experiments, rather more than half of the K balance remained extractable by ryegrass from the plots with a rotation of crops, and apparently all of the K balance from those under continuous grass. About one-fifth of the K balance remained extractable by ryegrass from the soils in the Rothamsted Classical experiments and soils given FYM retained K slightly better than other soils. With all soils about half the K extractable by ryegrass was exchangeable to ammonium acetate.The plots with FYM or under continuous grass contain more organic matter than other plots in the same experiments. The following possible effects of increasing the organic matter content of the soils were investigated by calculating the multiple regressions of K, and KB on K balance with either percentage of organic C, total CEC, or organic CEC:(1) loss of K decreased by increasing the water retention and lessening leaching;(2) improved K retention by increasing the total cation exchange capacity (CEC) available for K absorption;(3) improved K retention by a mechanism arising from the different selectivities of clay and organic matter for K relative to Ca.In the Classical experiments, where organic matter usually increases because of FYM additions, effect (2) seems the most probable, perhaps because the K given in the FYM was already absorbed by organic exchange sites. In the Ley–Arable experiments, where the K was given mainly as soluble K fertilizer and the organic matter develops mainly under grass, effects (1) or (3) seemed to operate, probably simultaneously.The Woburn Ley-Arable experiment had no continuous grass plots, the soils differed little in organic matter content and no deductions could be made.
