The research aim was to determine the influence of different organic and mineral fertilization treatments and post-harvest treatments on the content of nitrogen and crude proteins in the edible part of beetroot (Beta vulgaris var. conditiva). A field trial (2003-2005) was set up in a hilly part of Croatia according to the Latin square method with four types of fertilization (control, 50 t ha-1 stable manure, 500 and 1000 kg ha-1 NPK 5-20-30), while treatments involved harvested fresh beetroot and stored fresh beetroot. The highest dry weight (DW) content was determined in climatologically favourable 2004 (average 14.8% DW) and in the treatment with 1000 kg ha-1 NPK 5-20-30 (15.6% DW) in harvested beetroot. In 2004 and 2005, the highest levels of nitrogen and crude proteins in harvested beetroot were determined in the treatment with 1000 kg ha-1 NPK 5-20-30 (2.41 and 2.43 g N kg-1 in fresh weight and 15.07 and 15.21 g crude proteins kg-1 in fresh weight, respectively). Regardless of fertilization treatment or studied year, nitrogen and crude protein contents were higher in stored than in harvested beetroot, by 12% on average. The lowest crude protein content was determined in treatment with stable manure what confirmed that protein content decreased by organic fertilization. It can be concluded that beetroot lost some water during the storage period, which increased its content of nitrogen and crude proteins in fresh weight and thus increased the nutritional quality of beetroot as a functional food.

Significant Difference

This study investigated the influence of treated greywater on growth and protein content of multipurpose (forage and ornamental) transplants, Prosopis juliflora L., Prosopis tamarugo L., and Albizia lebbeck L. Transplants of tested species were irrigated with treated greywater, diluted greywater (grey + distilled water, 1:1/by volume), and distilled water (control) for seven months. Water quality analysis showed that the concentrations of nutrients and heavy metals found in the greywater were within the acceptable range compared with Jordan Institution for Standard and Metrology (JISM) and the World Health Organization (WHO) thresholds for safe use of greywater. Escherichia coli found in the greywater were lower compared to JISM and WHO guidelines for the safe use of greywater. Irrigation with treated greywater increased shoot fresh weight by 24–39% and dry weight by 34–40% compared to diluted greywater and control. No significant difference in crude protein was noticed between water treatments. Prosopis species (P. juliflora Albizia lebbeck L. and P. tamarugo Albizia lebbeck L.) had higher shoot fresh (35%) and dry weight the same species had lower crude protein (44%) when compared to Albizia lebbeck Albizia lebbeck L. The reuse of treated greywater for landscaping or forage production alleviates the demand for water resources and reduces the pressure on wastewater treatment plants. However, considering the controversial findings of previous studies on greywater quality (especially, long-term reuse), the reuse of treated greywater needs to be considered with caution and periodic quality analyses and economic assessments are required.

Produce Acid

This study, using miniature silos, bas shown that sorghum cut at the booting stage can produce acid silage. Such early harvesting produced silage with a crude protein content of 10 per cent of its dry weight, did not significantly reduce the yield per acre of silage protein, but reduced the yield of silage by some 40 per cent. Sorghum cut before the booting stage failed to produce satisfactory acid silage. Thic could not he explained by low initial sugar contents. Also, a comparison of the fermentation behaviour over the range of crop maturities in miniature silos and water slurries suggests that physical conditions, such as moisture contents and the release of cell constituents, had little influence on the development of acidity.

Phleum Pratense L

An experiment was set up to determine the effect of time and rate of nitrogen fertilization and stage of growth at first cut on yield and digestibility of dry matter and protein content of two timothy (Phleum pratense L.) cultivars, at each of two cuts, No difference in yield or chemical composition was found between cultivars. Highest yields and crude protein contents were measured at rates of nitrogen fertilizer of 112 and 224 kg/ha. Higher yield and protein content were obtained with NH4NO3 applied totally or in split applications in the spring than with urea in the fall. Dry matter digestibility (DDM) was not affected by nitrogen at rates of 56, 112 and 224 kg/ha. First cut was taken at two different stages of growth, and the second cut was taken on the same day in all the plots. At anthesis, yields were higher than at the head stage but DDM and protein content were lower. The opposite was found at the second cut. Except in 1973, total dry matter yield was not affected by the stage of growth at first cut.

SUMMARYSix castrated male cattle of 350 kg live weight were used in an incomplete Latin square design to measure intake and digestibility of barley straw offered ad libitum alone and with 5 levels, 1·5 to 7·5 kg/day, of a barley and dried lucerne concentrate. Straw intake declined and total organic-matter intake increased linearly with increasing concentrate level. On average 1 kg additional organic matter as concentrate, increased total organic-matter intake by 0·68 kg. There was no evidence that the crude protein content of the whole diet affected straw consumption.

A pot experiment was conducted to determine the effects of varying Cr (VI) levels [0.0–4.0 mg Cr (VI) kg-1 soil in the form of potassium dichromate] on the some quality parameters of sorghum Sorghum bicolor (L.). Quality parameters was measured in terms of protein content, chlorophyll content, and IVDMD ( In vitro dry matter digestibility) content at different growth stages, i.e. 35 DAS, 70 DAS and 90 DAS (Days after sowing) that were adversely affected with an increase in Cr (VI) levels from 0.0 to 4.0 mg Cr (VI) kg-1 soil. The decline in protein content 4.67 g/ kg dry weight at T4 was observed as compared to control (T1) ( 8.96 g/kg dry weight basis) at 35 DAS in leaves , Total chlorophyll content declined from 3.25 mg g-1 fresh weight (T1) to 2.40 mg g-1 fresh weight (T4) at 35 DAS and IVDMD content declined from 43.60 to 33.60 per cent dry weight basis with increment in chromium concentration. It is concluded that Cr (VI) at higher doses (4.0 mg Cr (VI) kg-1 soil) adversly affects the quality parameters of Forage sorghum Sorghum bicolor (L.) however, quality parameters are responsible for nutritive value of sorghum Sorghum bicolor (L.).

The experiment with natural meadow of Agrostis capillaris - Festuca fallax type in Rhodope Mountains (Smolyan region, Southern Bulgaria) shows that according to fertilization variants there is a clear tendency towards earlier start of active vegetation and its next phenophases. Most and almost equal amounts of dry biomass (4.38 and 4.31 t.ha-1) were reported in fertilization with N160P80K80 and N160P80, which exceeded the unfertilized control by 128.12 and 124.48%, respectively. Compared with unfertilized variant, the crude protein content increased in all fertilizing variants, as in complete mineral fertilization with N80-160 accumulates the crudest protein - respectively 314 g.kg-1 and 318 g.kg-1. As regards to other studying chemical indicators of the forage (crude fiber, crude fat, crude ash and nitrogen-free extract substances) the mineral fertilization also had an expressed positive effect.

Lactational Performance

Feeding extra protein as an attempt to increase amino acid flux to the intestine may increase lactational performance of dairy cattle. The objective of this study was to compare lactating dairy cow diets containing 16% crude protein (CP), adequate in rumen degradable protein (RDP) and metabolizable protein (MP) according to NRC (2001), with diets containing 17.5% CP. Forty-two Holstein cows (27 primiparous and 15 multiparous, with 172 days in milk) were used in a 3 ´ 3 Latin Square design with 14 replicates. Control diet consisted of 16% CP, adequate in RDP and MP . Crude protein content of diets was increased to 17.5% by feeding extra soybean meal and cottonseed meal (SBCS17.5) to increase diet MP, or extra urea (U-17.5) to increase diet RDP. The experiment was carried out during 60 days with three periods. Animals were group-fed a total mixed ration and milked twice a day. Dry matter intake was higher for the U-17.5 diet (p < 0.15) than for the control diet. Milk (p < 0.01) and 3.5% fat corrected milk (FCM-3.5%) (p < 0.05) yields were increased by extra soybean and cottonseed meal (SBCS-17.5) but not by extra urea (U-17.5). Milk fat content and yield were not affected by treatments (p > 0.05). Milk protein content decreased (p < 0.01) by feeding extra urea (U-17.5). However, higher (p < 0.01) protein yields were observed for the SBCS-17.5 treatment. For cows milking around 29 kg d-1, increasing diet CP content to 17.5%, by feeding extra soybean and cottonseed meal, beyond recommendations for RDP and MP, increased yields of milk, yields of 3.5% fat corrected milk and yields of milk protein.

Nitrogen Treatments

1. A small-scale plot experiment which had been carried out from 1947 to 1949 (Holmes, 1951) to study the effect of massive dressings of nitrogen, with and without phosphate and potash, on the yield of a ryegrass dominant sward was continued in 1950–2. A 4 × 4 Graeco-Latin square was used.The nitrogen treatments applied each year were:(1) no nitrogenous fertilizer, (2) 260 lb., (3) 520 lb. and (4) 416 lb. (312 lb. in 1951) nitrogen per acre per annum applied in four or five equal dressings, one for each cut. Treatments 1, 2 and 3 were cut each time they reached the long leafy stage (8–11 in. in height), treatment 4 was cut when 13–16 in. in height.The mineral treatments were (A) no mineral fertilizer, (B) 336–538 lb. K2O per acre per annum depending on nitrogen treatment, (C) 120–180 lb. P2O5 per acre per annum, (D) treatments B and C combined. Mineral applications were applied in four or five dressings each year, one for each cut.2. Applications of phosphate did not affect the yield or protein content of the herbage, but yields were severely restricted in the absence of potash. Where potash was applied the yields under each nitrogen treatment were maintained or increased over the 6-year period. Average yields of dry matter for the 6-year period when potash was present were 4760, 8050, 9620 and 9320 lb. per acre per annum for treatments 1, 2, 3 and 4. Without potash the corresponding average yields were 3980, 5610, 5190 and 5100 lb. Average crude protein yields with potash were 710, 1410, 1990 and 1640 lb. per acre per annum and without potash 550, 1090, 1190 and 1020 lb.3. The presence of potash resulted in earlier growth in each season through the maintenance of the earlier vigorous grasses in the sward. Although the growth curve was variable with treatment 1, treatments 2, 3 and 4 gave nearly uniform distribution of herbage production over the season.4. The weighted mean contents of crude protein for each year ranged from 13·9% for treatment 1 to 20·6% for treatment 3 when potash was given and from 12·9% for treatment 1 to 23·6% for treatment 3 when potash was absent. There was a gradual increase in protein content at the later cuts in each season, but the range was less where nitrogen was applied.5. The efficiency of utilization of fertilizer nitrogen was calculated. When the yield was compared with that of a no-clover sward the average response was 15·6, 10·8 and 11·8 lb. dry matter per lb. of nitrogen applied for treatments 2, 3 and 4 respectively. In terms of crude protein the percentage recovery was 53, 44 and 42 respectively. When the yields were compared with those of the clovery swards the nitrogen recovery figures were reduced by about one-third.6. The botanical composition of the plots was determined by the nitrogen and potash treatments. Where both were adequate a vigorous sward of ryegrass and timothy was maintained. Where nitrogen was absent but potash present a clovery sward developed. In the absence of potash with or without nitrogen the better grasses declined and were replaced by poor grasses.7. Provided potash was applied there were no marked changes in the soil analysis.8. The results are discussed with particular reference to the maintenance of high grass yields and the relative roles of clover and fertilizer nitrogen.

ABSTRACTGrass silage with a dry-matter content of 19·4% and containing 16·7% crude protein was offered ad libitum to 42 first lactation British Friesian cows during the first 75 days post-calving. In addition the animals received supplementary concentrates containing either 10·3, 13·6, 17·3, 21·1, 25·2 or 30·3% crude protein on a fresh weight basis, with extracted soya bean meal being used as the main protein source. All concentrates were offered at an equal level of 8·0 kg per day. The relationship between milk yield and protein content of the supplement was curvilinear and was described by the following equation:Y= 8·95+ 1·0×–0·0205×where Y = milk yield per day in kg, and × = percentage protein in the supplement. This equation indicated that maximum milk yield was obtained with a concentrate containing 24·4 % protein on a fresh weight basis. The protein content of the milk was also curvilinearly affected by the level of protein in the supplement, and it was calculated that maximum milk protein (nitrogen × 6·38) would be obtained with a supplement containing 23·9% protein. Plasma blood urea levels increased linearly with increasing protein intake. The effects on live-weight change and blood components were also recorded.

This study aimed to analyze the quality of chemical and chlorophyll content of alfalfa plants with lenght of irradiation and dose of dolomite on the regosol soil. The experiment was conducted implemented in Greenhouse Laboratory Forage and Pasture Faculty of Animal Sciences University of Gadjah Mada, from May to September 2015. This study used a Completely Randomized Design (CRD) 3 x 3 factorial design with two factors treatments and four replications. The first factor is the dose of dolomite (D) with 3 treatment (D0 = without dolomite, D1 = dolomite 6 t/hectare or 90 g/polybag and D2= dolomite 12 t/hectare or 180 g/polybag). The second factor is the length of irradiation (C) with 3 treatments (C0 = irradiating 12 hours, C1 = irradiating 14 hours and C2 = irradiating 16 hours). Data were statistically analyzed using analysis of variance and significant results continued with Duncan test at 5% level.Parameters measured were the proximate analysis (dry matter, organic matter, crude protein, crude fiber, crude fat, ash) and alfalfa chlorophyll content. The results showed that there was no significant interaction effect between lenght of irradiation and dose of dolomite treatment to the dry matter content, organic matter, crude protein, crude fiber, crude fat, ash and alfalfa chlorophyll content. The treatment lenght of irradiation are significant (P<0,05) of the organic matter content and ash content of alfalfa. Dose of dolomite treatment was not significant on all parameters of the study. The results showed that the treatment and dosage of radiation are dolomite not significant on the production of plant fresh weight, dry weight of plants, dry matter content, organic matter, crude protein, crude fiber, crude fat, ash and content alfalfa chlorophyll. No interaction between treatment and dosage of radiation are dolomite which significantly affect production plant fresh weight, dry weight of plants, dry matter content, organic matter, crude protein, crude fiber, crude fat, ash and alfalfa chlorophyll content. (Keywords: Alfalfa, lenght of irradiation, dolomite,  regosol soil)
