Although lucerne substantially outproduces pasture in the 350-800 mm rainfall environment of Central Otago, the area has only been maintained in two counties - Vincent & Lake. In the third, Maniototo, the area has declined. Impeded drainage with wet seasons is considered a cause. The identification of areas suitable for lucerne establishment is aided by a soluble aluminium test of the soil and profile examination. In Central Otago pest incidence is low and disease is only a problem on irrigated lucerne. Lenient management in the autumn and early spring will aid total production. Keywords: establishment, soil-test, pests, disease, management

'Grasslands Matua' prairie grass (Bromus catharticus) was evaluated under close mowing (a) against cocksfoot, phalaris, and tall fescue as a companion grass for lucerne, on a pumice soil from 1974 to 1977 at sowing rates of 4, 13 and 22 kg/ha and (b) against ryegrasses in grass/white clover pastures on a sandy loam from 1975 to 1977. (a) In the first year lucerne/Matua sown at 13 and 22 kg/ha outyielded lucerne/Matua sown at 4 kg/ha by 19%, lucerne alone by 61%, and other mixtures by at least 21%. There were no significant differences in total production between the three lucerne/ Matua treatments, luccrne alone, and other mixtures over the second and third year. The inclusion of Matua reduced weed ingress. In the third year, Matua had a higher weed content than lucerne/tall fescue, which was almost weed free. (b) Annual production of Matua and Nui ryegrass swards was not significantly different. Matua swards were, however, superior to Nui from midsummer to early spring, whereas over spring/early summer Nui swards outproduced Matua swards.

The recent progression and Green Revolution (approx. between the 1990s-2010s) in agriculture of Bangladesh resulted in an increase of total production despite yield-gap to ensure food security. But agriculture in Bangladesh is still backed-up by higher use of inputs (agrochemicals-fertilizers, pesticides; modern varieties, irrigation etc.) and inversion tillage. This conventional agrochemical-based smallholder agriculture may lead to soil and environmental degradation, soil acidification, and a decline in soil fertility. Therefore, it is significant to optimize input application in intensive agriculture, especially fertilizers. This paper introduces the potential online facilities of generating online fertilizer recommendations for smallholder farmers in Bangladesh to ensure proper usage of fertilizers and enable sustainable agricultural production. We also highlighted how the usage of fertilizers increased with an increase in total production over time. But the sustainability of production in the years to come still remain challenging. With the aim of sustainable crop production, reduction in the misuse of fertilizers and reduction of input cost by optimizing the present pattern of excessive fertilizer application, the Soil Resource Development Institute (SRDI) provides location-specific fertilizer recommendation through both the manual and soil test based interpretation of plant nutrients: soil database in Upzazila Nirdeshika and static laboratory soil analysis. Recently, SRDI developed web-based software named Online Fertilizer Recommendation System (OFRS). The system is capable of generating location-specific fertilizer recommendations for selected crops by analyzing the national soil database developed by this governmental institute. The software requires farmer field location, respective soil and land type, and crop type and variety information to generate crop-specific instant fertilizer recommendation. It was observed that by using fertilizer according to the recommended dose calculated on the basis of soil test values, farmers could harvest approx. 7-22% higher yield of different crops over usual farmers practice. If this system can be popularized and disseminated by effective agricultural extension, this would immensely contribute to the promotion of precision agriculture, input cost reduction and it would certainly enable us to optimize fertilizer application by the smallholder farmers in Bangladesh.

Abstract. In the article were presented the results of studying the early spring synusias in the forests of Fageto-Carpineto-Querceta roboris subformation on the Pricarpathian territory. In the studied subformation were separated five associations: Fageto-Carpineto-Quercetum roboris galiosum odorati, Fageto-Carpineto-Quercetum roboris caricetum pilosae, Fageto-Carpineto-Quercetum roboris vincosum, Fageto-Carpineto-Quercetum roboris galeobdolosum, Fageto-Carpineto-Quercetum roboris hederosum. The revealed early spring synusias are formed by the following herbal species: Leucojum vernum L. (Amaryllidacea), Galanthus nivalis L. (Amaryllidacea), Dentaria glandulosa Waldst. et Kit. (Brassicaceae), Anemone nemorosa L.(Ranunculaceae), Scilla bifolia L. (Liliaceae), Isopyrum thalictroides L. (Ranunculaceae), Corydalis cava (L.) Schweigg. Koerte (Papaveraceae) та Gagea lutea (L.) Ker.-Gawl. (Liliaceae). It appears before the leaves blooming and forms the specific white-lilac-blue aspect. Galanthus nivalis L. synusias develops the first and then in the third decade of March develops the group with Anemone nemorosa L. domination. Last years as the result of the negative anthropogenic influence the number of Leucojum vernum L. and Galanthus nivalis L. groups – the rare ephemeroids put to the Ukrainian Red book was abruptly shortened.

The paper presents data on the cattle industry in the People's Republic of China and the Republic of Serbia. China is the third largest dairy producing country and the third largest beef producing country in the world. In 2011, the dairy cow population in China was 14.4 million. Chinese dairy breed is mainly obtained by grading hybridization from Holstein, Simmental, etc. which were introduced from foreign countries, and local cattle breeds for long time to form the offspring with stable genetic characteristics. Currently, the dairy breeds cultured in China mainly include Chinese Holstein, Chinese Simmental, dairy buffalo, Brown cattle, Sanhe cattle, etc. Chinese Holstein accounts for about 80% of the total dairy cattle. From 2000 to 2007, Chinese beef production has always been in a rapid growth phase, with an increase from 5.054 million tons to 6.134 million tons, reached a historical highest level of 6.355 million tons in 2009, but rapidly declined since 2009, and dropped to 5 million tons in 2011. In addition, the amounts of reproduction cow and beef cattle in stock were also declined. In 2011, there were about 32.7 million beef cattle slaughtered, and the beef cattle population was about 80 million at the end of 2011, the beef carcass yield was about 5.5 million tons, the national average carcass weight was 201.5kg/cow, and the production value of beef cattle was about 200.75 billion Yuan. Currently, the amount of reproduction cow in stock declined sharply; the contradiction between the lack of cattle resource and the continued growth of beef consumption is more and more serious. Chinese dairy farming is mainly concentrated in the North, Northeast and Northwest of China, the dairy cows population in Inner Mongolia, Xinjiang, Heilongjiang and Hebei account for 60% of the total population in China; the beef cattle is mainly concentrated in rural areas as Henan, Shandong and Hebei provinces, accounting for 80% of the national amount of slaughtered beef cattle. In recent years, the superior regions of beef cattle breeding have been gradually shifted towards north and southwest. The beef cattle industry in Heilongjiang Province, Sichuan Province, Yunnan Province and Guizhou Province has been developed rapidly. The beef cattle breeding in pastoral areas are mainly concentrated in Inner Mongolia, Xinjiang and Gansu province. Cattle production is important branch of livestock production in Republic of Serbia. Current situation in cattle production is not satisfactory in regard to the production per head and number of heads which has been constantly decreasing in recent years. Based on official statistical data, current situation in cattle production is considered as unfavourable (Bureau of Statistics of Republic of Serbia). Number of cattle in 2011 was 936.000 heads and constantly decreasing over the last 11 years. In this period, number of cattle is reduced by 18%, and number of cows and pregnant heifers by 14%. Data on number and categories of cattle also indicate considerable reduction, so category of cattle at the age of 1 to 2 years has been reduced by 24.5%, and number of calves by 29.2%. Production of cow milk is relatively steady. In 2011 milk production was 1.434.000liters. This can be explained by increased production of milk per cow. Genetic progress in milk traits was achieved by utilization of progeny tested bulls on milk and increased scope of artificial insemination of cows and heifers. Production of meat is in constant decrease which is consequence of reduction of total number of cattle as well as insufficient number of slaughterhouses with EU certificate. Meat production in 2011 was 81.000 t. Our country, although without developed cattle breeding, has been traditional exporter of beef, meat products and fattening young cattle into many countries, even the most developed ones, for instance Italy and Greece. Export of beef was in expansion prior to Italy (1974) and Greece (1980) entering the EEC. For instance, in year 1974, we exported 50.500 t/annually on Italian market, i.e. in 1980 51.310 t and there were 24 registered slaughterhouses with EEC certificate. Today, there are only a few slaughterhouses with EU certificate, and approved export quota of close to 8.000 t of beef we cannot realize. Total production of milk is 1,434.000 l. Cattle production is expected to provide high quality products for export, primarily beef and quality cheeses with defined origin and quality.

This chapter examines the measurement of motion in agriculture. Not only in Brazil, but in several Latin-American countries, important changes have been observed in the geographical distribution of the agricultural activity. They may take different forms, such as occupation of new areas or reallocation of particular products to areas that were already under some form of agriculture. Besides, in any year, for a given level of geographical subdivision, the distribution of a product shows spatial concentration; but the places which concentrate a substantial portion of the total production may change from year to year, and different subsets of the total territory occupied by a product may move at different speeds. Three distance measures will be introduced in order to assess the motion of individual products; two of them correspond to mathematical concepts, while the third one gives the terrestrial distance between national centers of gravity of the products.

Seasonal variations in different forms of extractable sulfur (S) were examined in three New Zealand soils under permanent pasture. The concentrations of total extractable S, extractable inorganic sulfate-S (SO2-4-S), and extractable organic HI-reducible sulfur (HI-S) and carbon-bonded sulfur (C-S) were determined in field moist samples using four different extractants. During the course of the year, extractable SO2-4-S levels varied substantially. Concentrations of SO42--S in the soils peaked in the early spring and, for two of the soils, remained at relatively low levels throughout the rest of the year. The third soil, however, following a decrease in concentration in late spring, showed a continuous increase in SO2-4-S during the summer and autumn period. Concentrations of extractable organic C-S in soils were generally highest in the winter and declined significantly during the spring. Extractable organic HI-S concentrations fluctuated throughout the year with no clear trends. The proportions of the three forms of extractable S in soils also varied seasonally. The proportions of extractable organic HI-S in soils were more constant compared with the other two forms of S and generally accounted for less than 20% of the total extractable S. The seasonal changes in the proportions of SO2-4-S appeared to be inversely related to the changes in extractable C-S. This suggests that under the field conditions, the extractable organic C-S fraction is readily mineralized to sulfate when conditions are favourable for mineralization to take place.

This paper reports on both the individual and combined effects of age and liveweight at first calving (AFC and LWFC, respectively) for Australian Holstein–Friesian heifers on multiple lactation production. One hundred and thirty-five heifers were allocated to 1 of 3 AFC treatments. Within each AFC treatment, heifers were randomly assigned to 1 of 3 LWFC treatments. From 16 weeks of age until first calving, heifers in all groups grazed pasture and were provided with supplementary feed when the quantity and quality of pasture was inadequate to meet growth requirements. Mean AFC and LWFC achieved were 25.1 ± 0.121, 29.9 ± 0.11 and 33.9 ± 0.09 months and 498 ± 4.09, 549 ± 5.40 and 595 ± 5.09 kg, respectively. As AFC increased, total production over the first 3 lactations increased. For each month's delay in AFC an extra 56.7 L milk, 1.78 kg milk fat, 1.45 kg milk protein and 3.23 kg fat + protein over the first 3 lactations was produced but by the third lactation the response was minimal. By end of third lactation the remaining heifers that calved at 25.1 months AFC were producing similar amounts to those that calved at the older AFC. As LWFC increased from 498 to 595 kg, production over the first 3 lactations increased. The response to an extra kilogram increase in LWFC was 4.82 L milk, 0.20 kg milk fat, 0.18 kg milk protein and 0.38 kg fat + protein over the first 3 lactations. The greatest benefit was when LWFC increased from 498 to 549 kg. Increasing LWFC from 549 to 595 kg did not significantly increase milk, milk fat and milk protein yields from the second to third lactation. The combined effects of AFC and LWFC indicated that to reduce the negative effects on production due to decreasing AFC, LWFC would have to increase by 7.2, 2.9 and 2.2 kg for each month decrease in AFC (for milk, fat and protein production, respectively). By the end of the third lactation, only 58 heifers remained in the herd. The number of heifers remaining within the 9 groups ranged from 4 to 10. Increasing LWFC while decreasing AFC reduced the chances of a heifer remaining in the herd but this may have been biased by the feeding regime imposed during lactation. Responses to increasing AFC decreased as the number of lactations increased, indicating that heifers calving at younger AFC produce similar amounts to their older herd-mates by the end of third lactation. Increasing LWFC from 498 to 549 kg had the greatest benefits for yield, indicating a possible maximum LWFC of 549 kg for our study. Therefore, the negative effects due to decreasing AFC can be offset in part, by increasing LWFC. However, on-farm resources and ultimately milk price will determine the choice of combination of AFC and LWFC.

Weeds can infest management-intensive grazed pastures and impact forage quantity, forage quality, and animal health. Common burdock, plumeless thistle, and Canada thistle are three common pasture weeds in the midwestern United States that are managed to avoid these impacts. Experiments were established at two sites to determine if increasing grazing heights from fall through summer would reduce emergence and survival of burdock, plumeless thistle, and Canada thistle seedlings. Five simulated grazing heights (5, 10, 15, and 20 cm and a not-clipped treatment) were implemented in October 2008 and repeated in May through August. Density of all species was reduced from May to September, with reductions ranging from 65 to 78%, regardless of treatment. Treatments that left at least 15 cm of residual grass had reduced densities of burdock and Canada thistle compared to the 10-cm treatment. Regression analysis demonstrated that reduction in burdock and summed planted weed density was related to increased intercepted photosynthetically active radiation from forage in April. However, total biomass yield was reduced up to 60% when grazing heights were increased from 5 to 20 cm, although differences were only observed at the fall and early spring grazing events. Relative forage quality (RFQ) was similar across treatments, except at the third grazing event for which the 15 and 20-cm treatments had reduced RFQ compared with other treatments. Results suggest that increasing grazing heights can reduce emergence and survival of burdock and Canada thistle but can also result in a reduction in forage quantity in the fall and early spring.

Тривалими польовими дослідженнями доведено, що в північному Степу України чим пізніше відновлюється весняна веґетація озимої пшениці, тим меншою є врожайність. При цьому час відновлення веґетації має значний вплив на врожайність різновікових посівів. У разі надраннього відновлення веґетації (III декада лютого) врожайність  посівів з сівбою у період з кінця серпня до початку жовтня є майже однаковою і становить від 6,44 до 6,96 т/га. У випадку пізнього відновлення веґетації (початок квітня) найбільш високу врожайність формують посіви з сівбою з 10 по 25 вересня. Їх врожайність у середньому за роки досліджень становила 3,86–3,91 т/га. Чим коротшим є період від переходу температури через 0 0С до +5 0С, тим більшою є врожайність озимої пшениці. У середньому за роки досліджень врожайність озимої пшениці за тривалості періоду від переходу температури через 0 0С до +5 0С до 10 днів становила 6,04 т/га, а в разі подовження цього періоду до 30 і більше днів зменшувалася до 3,76 т/га. It has been established that in the Northern Steppe of Ukraine the beginning of spring vegetation of winter wheat starts at different periods of time. The earliest vegetation (February 22) was observed in 1990, and the latest vegetation (April 4) was in 2003. Therefore, it has been suggested to distinguish the very early (the third decade of February) beginning of vegetation, early beginning of vegetation (the first–second decade of March), middle-time vegetation (the third decade of March) and late beginning of vegetation (the first decade of April) of winter wheat. During the whole period of observations from 1986 to 2005, the  very early beginning of vegetation was observed during 3 years (15%), early vegetation – 4 years (20%), middle-time vegetation – 8 years (40%), and late vegetation – 5 years (25%). The analysis of winter wheat productivity shows that the later is the beginning of spring vegetation, the less productivity of winter wheat. During the very early spring vegetation in the third decade of February,  productivity is twice as large as compared with the late vegetation in the first decade of April. On average, over the years of the study, these indicators were 6.74 and 3.28 t/ha respectively. In the very early vegetation (the 3rd decade of February), productivity of the mixed-age crops is almost the same and ranges from 6.44 to 6.96 t/ha. During the late vegetation (early April), the highest productivity is formed by the crops sown from the 10th to the 25th of September. Their average productivity during the years of the study was 3.86–3.91 t/ha. With this period of spring vegetation, the productivity of crops sown on September 2nd and October 2nd is almost the same and is 2.99 and 2.88 t/ha respectively, but significantly higher than the productivity of crops sown on August 25th. For the formation of winter wheat harvest, the change of the average daily temperature above 0 °C is important, as well as the duration of the period from that time to the beginning of spring vegetation. That is the steady increase in average daily air temperature to more than +5 °С. The increase in the period of time from the date of the change of the average daily air temperature above 0 °C to the beginning of spring vegetation causes the decrease in the productivity of winter wheat. During the years when the duration of this period was up to 10 days, the productivity of winter wheat averaged 6.04 t/ha, and during the years with this period of more than 30 days, the productivity decreased to 3.76 t/ha. The shorter period from the change of the average daily air temperature above 0 °C to the time of the beginning of spring vegetation, the higher the dependence of the level of winter wheat productivity on the sowing terms. If this period is longer than 30 days, the highest productivity was formed by crops sown on September 17th and September 25th, and during the years when this period lasted from 10 to 20 days, higher productivity was provided by the crops sown from September 10th to September 25th. With the duration of the period from the date of the change of the average daily air temperature above 0 °C to the beginning of spring vegetation to 20 days, the productivity of winter wheat crops with early sowing on September 2nd and October 2nd is almost the same. The crops sown on September 2nd with the duration of this period up to 10 days formed productivity of 5.44 t/ha, and the crops sown on October 2nd – 5.56 t/ha. At the same time, if the duration of this period exceeds 20 days, the crops sown on October 2nd form a considerably higher productivity than the crops sown on September 2nd.
