Bean Crop

In the Middle Volga region, alfalfa is the most widely used bean fodder. In recent years, one more bean crop is used – Fodder galega. The main disadvantage of almost all legumes is low sugar content and poor haylage making abilities. To eliminate this drawback, the biological product “Silostan” was developed. It is used as a preservative. The aim of the work is to study the effect of alfalfa and Fodder galega haylage made using the bio-preservative “Silostan” on milk production and quality of milk of black and white Samara cows. The use of Silostan increased the dry matter content by 5.2 and 4.5, ECE – by 12.8 and 17.5%, and digestible protein – by 27.1 and 15, 5%. The digestibility of dry matter increased – by 3.85 and 4.38%, crude protein – by 5.68 and 5.42%, crude fat– by 4.26 and 5.26%, crude fiber by 3.86 and 4.07%. The use of haylage with bio-preservatives increased the yield of cows for 305 days of lactation by 14.6 and 16.5%. The MFF increased by 0.05 and 0.06%, MFP – by 0.07 and 0.09%, respectively. The technological properties of milk improved, the milk consumption per 1 kg of ripened cheese decreased by 4.9 and 11.2%.

The aim of the research was to study the effectiveness of an application of increasing doses of potash fertilizers in the potatoes cultivation of the middle-early ripeness group of Gala variety on the background of the use of nitrogen-phosphorus fertilizers and sulfur in the dose of N90Р120S30. Studies were carried out in 2016-2018. The soil of the experimental site of gray forest medium loamy granulometric composition had the following agrochemical characteristics: pH of salt extract - 5.4-5.7; humus content - 3.28-3.41%; easily hydrolyzed nitrogen - 146-160 mg per kg; mobile phosphorus - 140-152, exchangeable potassium - 146-160 mg per kg of soil. Potassium fertilizers were applied in increasing doses - К30, К60, К90, К120, К150, К180 kg of the active substance together with the background fertilizers - N90Р120S30 and microelements deficient in this soil: copper, boron and molybdenum in the composition of ZhUSS-1 and ZhUSS-2. The influence of the studied doses of fertilizers on crop yield, dry matter content, vitamin C, starch and nitrates has been established. On average of three years, the productivity of tubers was 21.67 tons per hectare. When applying background fertilizers (N90Р120S30) compared with the control, it increased by 4.32 tons per hectare. The optimal dose of potash fertilizer on the background of N90Р120S30 for potatoes grown under irrigation was К150, where the average yield of three years was 34.42 tons per hectare. A further increase in the dose of fertilizers did not significantly increase the productivity. On average of three years, the highest dry matter content was 22.81% and starch - 13.15% was noted in the variant, where potassium was applied in a dose of К180 kg of the active substance together with background fertilizers and microelements. With the introduction of high doses of potassium (К150 and К180 kg of the active substance), the content of dry matter and starch did not significantly differ from those in the control.

Yield And Quality

The effects of nitrogen fertilization on the yield and quality of early potato (Solanum tuberosum L.) were studied at MTT Agrifood Research Finland during 1996–1997. Cultivars were harvested at three times. The experimental layout was a split-split-plot with harvest times as main plots and nitrogen fertilization and potato cultivars as the subplots. The fertilizer treatments were 60 and 120 kg N ha-1 and the cultivars tested were Timo, Gloria and Van Gogh. The harvest times were 57–62, 70–75 and 85–90 days after planting. Application of 120 kg N ha-1 intensifi ed canopy development and increased leaf area of the stands. At early harvest the tuber yield of all cultivars receiving the higher nitrogen application increased by 0.5–2.5 t ha-1. The highest yielding cultivar was Timo. At last harvest, the higher nitrogen treatment increased yield by 3.0–6.2 t ha-1. The highest yielding cultivars were Timo and Van Gogh. The dry matter content of tubers was very low, 13.8–17.2%, at the fi rst harvest and the higher nitrogen application reduced dry matter content by 0.3–1.0%. The highest fertilizer application rate resulted in the largest tuber size. Nitrogen application, however, affected the quality of potatoes by decreasing the dry matter content. The nitrate content in tubers increased signifi cantly with the increasing level of nitrogen. The range of nitrate content in tubers fl uctuated between 13 and 189 mg kg-1 fresh weight showing good controlling of nitrate values. Harvest time affected sucrose content and the reducing sugar content in tubers, but nitrogen fertilizer did not change the sugar content of tubers. As tuber yield and quality during a short growing season are affected mainly by intercepted radiation, methods to increase tuber yield should focus on reducing the time to emergence, improving haulm growth after emergence and increasing the harvest index.;

Maize was harvested with a precision chopper and ensiled in five plastic tower silos, 1 500 kg fodder/silo. The silages and the ensiling methods were: 0.5 % urea per fresh weight (A), 1.0 % urea per fresh weight + Viher-acid 4 1/1000 kg of silage (B), 0.5 % urea per fresh weight + Viher-acid 4 1/1000 kg of silage (C). Viher-acid 4 1/1000 kg of silage (D) and silage without urea or preservatives (E). The dry matter content of the whole maize was 21 % and the crude protein content was 10.8 % in DM. The addition of urea increased the crude protein (N x 6.25) content in A- and C-silages to 17.7 percent and in B-silage to 24.9 percent. The quality of the silages was good, and some marks of butyric acid was found only in the silage ensiled without Viher-acid or urea. The addition of Viher-acid lowered the fermentation rate so that the sugar content of the corresponding silages was higher. The sugar content was higher (P < 0.01) and the content of lactic acid lower (P < 0.001) in the silage ensiled only with Viher-acid. Urea increased the content of lactic acid and the content of acetic acid of the silages. In the silages ensiled with urea the use of Viher-acid tended to lower the fermentation rate. The use of urea increased the NH3-N (P < 0.05) and the soluble N contents (P < 0.001) in the silages. In spite of the low dry matter content of the silages some enrichment of the urea in the lower parts of the silos was only found in the silage ensiled with 1 % of urea (P > 0.05) and Viher-acid. This was due to the larger effluent amount from the silo. The fermentation losses of dry matter were smallest in the silage D (3.9 %) and highest in the silage E (11.6 %) (P < 0.05). The losses in A-, B- and C-silages were 7.6 %, 4.7 % and 9.2 %, respectively. The use of urea decreased the fermentation losses.

Research staff All-Russian Scientific Research Institute of Vegetable Growing – Branch of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center in collaboration with Russian state agrarian University – Moscow Timiryazev agricultural Academy conducted research (2014-2016) on the effect of fertilizers and plant growth regulators on changes in the quality of onions of the Pervenets F1, Bennito F1 hybrids and Poisk 012 F1 during storage. As a result of research, the greatest effect was obtained from the complex application of N90P90K90 in combination with trace elements (tenso-cocktail) and a growth regulator Zircon. This system allowed to obtain high biochemical parameters of onions. At the end of the 7 months of storage (October-may), the highest dry matter and sugar content and the minimum nitrate content was observed in Pervenets F1 onions, as well as in hybrid Bennito F1. In the latematuring hybrid onions Poisk 012 F1 at the end of storage, the dry matter content decreased to 6,8-7,3%, sugars to 3,6-4,1%, vitamin "C" to 3,2-4,9 mg%, and nitrates increased to 92,1 mg/kg, which led to a decrease in product quality and large losses of onions from diseases and natural losses (up to 48-59%). The main reason for these losses was the lack of maturity of bulbs,low solids and sugars during harvest. It is obvious that for long-term storage it is necessary to use bulbs with a dry matter content of at least 10%. It was found out that feeding of onions during the beginning of the formation of food organizations with potassium nitrate, treatment with a growth regulator of Zircon and a complex of microelements of tenso-cocktail contributes to better preservation of the quality of onions.

China is the origin and distribution center of kiwifruit, as well as the country with the largest cultivated area and output of kiwifruit. A previous study found that a new kiwifruit virus, Actinidia yellowing ringspot virus (AYRSpV), has been detected in kiwifruit samples with yellowed leaves. The incidence of this virus was high in kiwifruit plantings in Shaanxi Province. To determine the symptoms of this viral infection and the effects of this virus on the yield and quality of kiwifruits, we measured leaf chlorophyll levels and the fruit yield, total sugar, total acid and dry matter contents of ‘Hayward’ kiwifruits grafted with AYRSpV-infected scions. The results showed that after AYRSpV infection, symptoms including chlorotic ringspots were mainly observed in the spring and gradually recovered with high summer temperatures. A few of the leaves that did not recover showed symptoms of albinism, which lasted until the leaves fell. We found that AYRSpV infection could reduce the chlorophyll content of ‘Hayward’ kiwifruit by 74.61-76.64%, the fruit yield by 14.50-24.10%, the sugar to acid ratio by 50.09-50.57%, and the fruit dry matter content by 1.67-1.78%. Our results showed that AYRSpV infection could significantly affect the yield and quality of ‘Hayward’ kiwifruit.

An experiment was conducted at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh to evaluate the effects of sulphur and GA3 on the growth and yield performance of onion cv. BARI Peaj-1. The experiment included four levels of sulphur viz., 0 (control), 15, 30 and 45 kg/ha and four concentrations of GA3 viz., 0 (control), 50, 75, 100 ppm. The experimental findings revealed that sulphur and GA3 had significant influence on plant height, number of leaves per plant, bulb diameter and length, individual bulb weight, splitted and rotten bulb, bulb dry matter content and bulb yield. The highest bulb yield (13.85 t/ha) was recorded from 30 kg S/ha, while the lowest bulb yield (11.20 t/ha) was obtained from control. Most of the parameters showed increasing trend with the higher concentration of GA3. Application of GA3 @ 100 ppm gave the maximum bulb yield (15.23 t/ha), while the minimum value (10.10 t/ha) was observed from control. Almost all the parameters were significantly influenced by combined treatments of sulphur and GA3 except bulb length of onion. The maximum bulb dry matter content (13.50%) and bulb yield (17.10 t/ha) were produced from the application of sulphur @ 30 kg/ha with 100ppm GA3, while the minimum bulb dry matter content (9.23%) and bulb yield (9.33 t/ha) were recorded from control treatment of sulphur with GA3.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16749 Progress.

The aim of the present study was to determine the effect of nitrogen supply on yield and fruit quality of apple cultivars and to explore the relationships between canopy density and the different fruit quality parameters. The experiments were carried out at Kálmánháza, in Eastern Hungary in a private orchard in 2003-2004. The response of four apple cultivars ('Elstar', 'Gala Prince', 'Granny Smith', 'Idared') to different nitrogen dosages was studied. The assessed and calculated indices were: yield, fruit diameter, fruit height, shape index, fruit mass, firmness, dry matter content and colouration. The results indicated that nitrogen fertilization has a significant effect on the yield and fruit quality of apple cultivars. The calculated specific yield values were reduced by the application of nitrogen via the increase in the volume of the canopy. An opposit trend was observed for fruit diameter, fruit height and fruit weight, which increased with increasing nitrogen supply. The reduced shape index caused flattening of fruits. However, the improvement of fruit quality via increasing nitrogen dosage is only virtual, since these dosages increase the fruit size, but firmness, dry matter content and colouration are diminished, which decreases the value of the fruits on the market. The authors also studied the relationships between canopy density responsible for assimilation and light supply of the fruits and the different fruit quality parameters. The closest linear inversely proportional relationship was found in the case of colouration. There was a negative linear relationship between canopy density and firmness or dry matter content. The relationship between canopy density and fruit mass could be described by a quadratic polinomial function.

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.

SUMMARYPoultry manure and mineral fertilizers at two rates of application (medium and high) and in different combinations, together with a non-fertilized control, were tested at the Experimental Station of the Agricultural University of Padova, Italy (45° 21′ N, 11° 58′ E) in 1985–89.Compared to the control, all the fertilization treatments increased the incidence of larger-sized bulbs of onion and tubers of potato, improved the fruit colour of processing tomato and the raw protein content of spinach, but reduced the acidity and acids: soluble solids ratio of tomato and the dry matter content of spinach leaves.In addition, the application of 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as mineral fertilizer or as poultry manure gave the best scores of processing suitability of potato, both for sticks and chips. All the fertilization formulae, except for 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as poultry manure alone, showed significant decreases in the extractable sucrose ratio in sugarbeet, compared with the control. In processing tomato, the best scores of suitability for paste transformation were obtained with mixed fertilization (1/3 poultry manure and 2/3 mineral fertilizers) applying 210 kg/ha of N, 210 kg/ha of P2O5 and 150 kg/ha of K2O and the plots receiving only mineral fertilizers produced fruits with less favourable values of pH and electrical conductivity compared to the poultry manured ones.
