Emission Growth

This study was conducted to evaluate the dietary supplemental effects of 2-nitroethanol (NEOH) in comparison with monensin on methane (CH4) emission, growth performance and carcass characteristics in female lambs. Sixty female, small-tailed Chinese Han lambs (3.5 ± 0.3 month) were randomly allotted into three dietary treatment groups: (1) Control group, a basal control diet, (2) monensin group, the basal diet added with 40 mg/kg monensin, (3) NEOH group, the basal diet added with 277 mg/kg nitroethanol, and the feedlotting trial lasted for 70 days. Although dietary addition of monensin and NEOH did not affect nutrient digestibility of lambs, both monensin and NEOH decreased the calculated CH4 production (12.7% vs. 17.4% decrease; p < 0.01). In addition, the CH4 production represents less dietary energy loss in the monensin and NEOH group than in the control, indicating that monensin and NEOH are potent CH4 inhibitors that can reduce dietary energy loss. Dietary addition of monensin and NEOH decreased dry matter intake (p < 0.01); however, they increased the ADG of female lambs (p < 0.01). As a result, both monensin and NEOH increased feed conversion efficiency of the feedlotting lambs (p < 0.01), suggesting that feed energy saved from CH4 production promoted the feed efficiency and ADG in the present study. Except for the fact that NEOH addition increased the net muscle percentage to carcass weight (p = 0.03), neither monensin nor NEOH had a significant influence on carcass characteristics of female lambs (p > 0.05). From an economic point of view, NEOH and monensin caused a reduction in feed consumption costs, therefore resulting in a higher net revenue and economic efficiency than the control. In summary, dietary supplementation of NEOH in comparison with monensin presented a more promoting effect on energy utilization in female lambs by inhibiting rumen methanogenesis more efficiently, and NEOH improved the net revenue and economic efficiency more significantly than monensin.

Hourly Basis

Abstract Peanuts were mechanically cured from field moisture contents ranging from 11.5 to 32.8% wet basis to levels acceptable for marketing (< 10.5%) using two dryer control strategies. The first control algorithm consisted of a constant thermostat setting of 39 C, while the second required manual thermostat control on an hourly basis such that the minimum plenum relative humidity was between 40 and 60% and the maximum plenum temperature was less than 39 C. The average drying rate using the variable thermostat set point (0.3%/hr) was half that obtained with the constant set point (0.6%/hr). Average curing time for the variable thermostat setting was 56% longer than for the peanuts cured using the constant thermostat. Fuel consumption was reduced by approximately 30% using the variable set point. Kernel size distributions and milling quality indicated by bald kernels were significantly better (P ≤ 0.1) for peanuts cured using the variable thermostat control. Increasing available dryer capacity by 40% would allow the buying point manager to handle the same amount of peanuts during the same harvest interval. Economic analysis showed that the annual capital cost for additional drying equipment could not be offset by energy savings alone. Based on increased shelled product value and energy savings, shellers could realize an increase in net revenue of approximately $14/1000 kg of farmers stock peanuts by using a variable thermostat set point.

Field experiment was conducted during two consecutive years (2011-12 and 2012-13) to investigate the yield and water productivity (WP) of mustard (BARI Sarisha-14 variety) using sprinkler irrigation. There were six irrigation treatments (sprinkler irrigation at vegetative (T1), pre-flowering (T2) and pod formation (T3) stage, sprinkler irrigation at vegetative and pod formation stage (T4), sprinkler irrigation at pre-flowering and pod formation stage (T5); and basin irrigation at vegetative, pre-flowering, and pod formation stage (T6) (farmers practice). Results indicate that yield and yield components responded positively against different soil moisture regime. The significant highest yield (1.41 and 1.37 t/ha) was obtained by applying basin irrigation at three growth stages, with no statistical difference in yield (1.38 and 1.34 t/ha) with the application of sprinkler irrigation at vegetative and pod formation stages. Vegetative stage was the most critical stage to sprinkler irrigation and pod formation is the next most sensitive stage for mustard cultivation. Sprinkler irrigation can save more than 65 and 35 % of water with the yield reduction of 12.96 and 2.16%, respectively, in treatment T1 and T4 compared to treatment T6. These treatments (T1 and T4) also gave higher water productivity, irrigation water productivity, and net revenue than treatment T6. The results will be helpful for policy planning regarding efficient irrigation and water management under water scarce situation.Bangladesh J. Sci. Res. 28(2): 137-149, Dec-2015

O objetivo deste trabalho foi avaliar a viabilidade agroeconômica do tomateiro em sistema de tutoramento vertical em espiral conduzido com uma ou duas hastes por planta. O delineamento foi em blocos casualizados em esquema fatorial 3x2, com quatro repetições, sendo avaliados três métodos de tutoramento: espiral, mexicano e estacas de bambu individuais na vertical e dois sistemas de condução: com uma haste e duas hastes por planta. Avaliou-se a produção de frutos por planta, diâmetro dos frutos, distribuição do número de frutos por classe de tamanho, altura das plantas e de inserção do primeiro cacho e o custo de produção. O método de tutoramento em espiral apresentou produção de frutos por planta semelhante ao método com bambu e superior ao mexicano. Quando as plantas foram conduzidas com uma haste, o diâmetro de frutos obtido no método em espiral foi superior ao método mexicano, entretanto, não diferiu do método com bambu. A receita líquida obtida no método em espiral foi superior à do método mexicano e inferior a do método com bambu. O tutoramento bambu vertical apresenta maior rentabilidade econômica quando comparado aos métodos espiral e mexicano. O tutoramento em espiral pode substituir o tutoramento mexicano, pois apresenta maior rentabilidade, credenciando-se como um novo método de tutoramento para o cultivo de tomate de crescimento indeterminado.Palavras-chave: Lycopersicon esculentum Mill, sistema de condução, crescimento indeterminado. TOMATO PERFORMANCE IN VERTICAL TUNA SYSTEM IN SPIRAL CONDUCTED WITH ONE OR TWO HASTES ABSTRACT:The current study aims to evaluate the agroeconomic viability of the tomato in a spiral vertical steerage system conducted with one or two stems per plant. The experimental design was in a randomized block with a 3x2 factorial, with four replications, and three tutoring methods were evaluated: spiral, Mexican and individual bamboo stakes vertically and two systems of conduction: with oneortwo stems per plant. Fruit production per plant, fruit diameter, number of fruits per size class, height of plants and insertion of the first cluster and the cost of production were evaluated. The spiral tutoring method showed fruit production per plant similar to the method with bamboo and superior to the Mexican one. When the plants were conducted with a stem, the fruit diameter obtained in the spiral method was superior to the Mexican method, however, did not differ from the method with bamboo. The net revenue obtained in the spiral method was higher than the Mexican method and lower than the method with bamboo. The vertical bamboo tufting presents greater economic profitability when compared to the spiral and Mexican methods. The spiral tutoring can replace the Mexican tutoring, since it presents greater profitability, being accredited as a new method of tutoring for the cultivation of undetermined growth tomato.Keywords: Lycopersicon esculentum Mill, driving system, indeterminate growth.

The Impact

This is the first study which explores the impact of climate change in Sicily, a small Mediterranean region of Southern Europe. According to research, Mediterranean area has shown large climate shifts in the last century and it has been identified as one of the most prominent “Hot-Spots” in future climate change projections. Since agriculture is an economic activity which strongly depends on climate setting and is particularly responsive to climate changes, it is important to understand how such changes may affect agricultural profitability in the Mediterranean region. The aim of the present study is to assess the expected impact of climate change on permanent crops cultivated in Sicilian region (Southern Italy). By using data from Farm Accountancy Data Network and Ensembles climatic projections for 2021-2050 period, we showed that the impact of climate change is prominent in this region. However, crops respond to climatic variations in a different manner, highlighting that unlike the strong reduction in profitability of grapevine and citrus tree, the predicted average Net Revenue of olive tree is almost the same as in the reference period (1961-1990).

Using Data

In most developing countries, climate variabilities and discount rate played an integral role in the decision-making of farmers, which mostly affect their net revenue. Our study employs Ricardian models to empirically verify this hypothesis using data collected from three major agro-climatic zones in Ghana. We particularly estimated the comparative effect of climate change variability, discount rate, and soil fertility; due to trade-off effect of certain farm practices in response to climate change across major climatic zones and also the fact that discount rate becomes an extremely critical issue in formulating and evaluating conservation and management policy to address climate change. The result indicates that discount rate has a positive and significant effect on the farmers’ net revenue. Further, effect of changes in temperature on food crop production and hence net revenue is more felt in the forest and savannah zones. On the other hand, an increase in rainfall has significant negative effects on crop net revenues and whole-farm net revenue, but a positive effect on net revenue of farmers in the savannah zone. We also found a significant increase in soil fertility to increase crop net revenues.
