A study was carried out in three potato growing areas viz. Munshiganj, Bogra and Jessore covering 75 potato growers to measure technical efficiency and economic performance of potato production. Farmers obtained average tuber yield of 24.90 t/ha which was higher than the average yield of Bangladesh (14.90 t/ha) but close to potential yield (25-30 t/ha) of diamant and cardinal varieties. The estimated results showed that gross margin and BCR for potato cultivation were Tk. 174319/ha and 2.40, respectively. The average level of technical efficiency among the sample farmers was 75%. This implies that given the existing technology and level of inputs the output could be increased by 25%. Training on the potato production, extension linkage and quality seed played a significant role in the technical efficiency of the potato production.DOI: http://dx.doi.org/10.3329/jard.v6i1.1665J Agric Rural Dev 6(1&2), 113-118, June 2008

Sustainable development in potato production is an issue of growing concern. Today, population growth, the need to further the cause of human food, agricultural and energy development in the agriculture sector is. Excessive consumptionof food demand huge population the lack of stability in the future willproduce. The effect of planting technique on the yield of potato at charland ecosystem  has  been  investigated.  A field experiment was conducted at the MLT site Ulipur during rabi season 2012-13 and 2013-14 to observe the suitable planting techniques on tuber yield of potato at charland ecosystem. Four planting techniques viz., recommended system of planting (60cm×30cm), Single eye planting(30cm×10cm), Single eye double row zigzag system(10cm/30cm×10cm), and Half cut system(30cm×10cm),  were evaluated for this purpose. The experiment was laid out in a randomized complete block design with six dispersed replications. Among the tested planting techniques, the highest tuber yield (29.0 t ha-1) was obtained from recommended system of planting and the lowest yield was obtained from single eye planting (22.5t ha-1) system. The highest gross return (Tk.217500 ha-1) and gross margin (Tk.75000 ha-1) were obtained from recommended system of planting.Progressive Agriculture 27 (2): 144-148, 2016

Potato cultivation accounts for 5.71 percent in total cropped area of the Punjab province and it supplements the diet of the growing population at lower prices as compared to grains, meat and chicken. Data from 100 farmers, 50 each from the districts of Okara and Kasur during the year 2002-2003 (the autumn crop) has been collected. The study estimates the technical efficiency in potato production by employing the Cobb-Douglas stochastic production frontier approach. The null hypothesis of no technical inefficiency in the data is rejected. Our results indicate that potato farmers are 84 percent technically efficient, implying significant potential in potato production that can be developed. By shifting the average farmer to the production frontier, the average yield would increase from 8.33 tons per acre to 9.92 tons per acre using the available resources. The additional quantity of potatoes gathered through efficiency improvements would generate Rs. 990.81 ($16.51) million of revenue each year. Consultation with extension workers significantly contributes to the improvement of technical efficiency and implies that the extension department should be one of the major targeted variables from the policy point of view in order to improve technical efficiency in potato production.

This study established the level of technical efficiency and its determinants among the informal and formal seed potato producers in the southwestern highlands agro - ecological zone of Uganda. A multi- stage sampling procedure was employed to select 636 households (499 informal seed producers and 137 formal seed producers) from which data was collected for two seasons using a semi - structured questionnaire. Data was analyzed using the stochastic frontier approach with a one - step approach. Maximum likelihood estimates for the efficiency parameters showed that both informal and formal seed potato producers were not fully efficient. The mean technical efficiency for informal and formal seed potato producers was 8 1 .4 and 80.4 percent respectively. In terms of yield loss, informal and formal seed potato producers respectively lost an average of 981 and 1,208 kg/acre of seed potato tubers due to inefficiency factors . Specifically, off- farm income source, scale of production, seasonal variation, access to extension services and seed producer being male positively influenced informal seed producers’ technical efficiency while producers’ level of education and seed potato variety diversity negatively influenced their efficiency. For formal seed producers, technical efficiency was influenced positively by producers’ education and negatively by household size. The study suggests that there is an opportunity to improve technical efficiency of informal and formal seed producers by 19 and 20 percent respectively. Therefore, this calls for increased investment in developing and promoting high yielding varieties, provision of extension services, input intensification and addressing gender issues in seed potato production in the context of limited arable land .

SYNOPSIS This paper investigates the importance of role-specific performance measures and sociopolitical factors in the career paths of CFOs. We find that forced CFO turnover is associated with poor performance in functions over which they have more direct influence, including financial reporting, financing, and regulatory compliance. We also find that CFOs are less likely to be dismissed when they have greater connectedness with the CEO and have stronger influence within the firm. Interestingly, sociopolitical factors are linked with promotion outcomes, but economic performance does not appear to play a significant role. The collective evidence indicates that both economic and sociopolitical factors have an important role in influencing CFO career paths.

The Impact

PurposeThe purpose of this paper is to examine the impact of agricultural cooperative membership on potato production and technical efficiency.Design/methodology/approachA combination of propensity score matching technique and sample selection stochastic frontier framework that addresses potential selection bias due to observable and unobservable attributes is used to estimate the effect of participation between cooperative members and non-members. Using a stochastic meta-frontier approach, the technical efficiency of farmers was estimated and compared.FindingsThe empirical results show that the effect of participation in agricultural cooperatives is associated with increased yield and technical efficiency. A comparison of group-specific frontiers indicates that cooperative members perform better than non-members. Cooperative membership decisions is significantly associated with household and farm characteristics (e.g. education, participation in off-farm work, total farmland, distance to market and geographic location).Practical implicationsThe findings of this study demonstrate that cooperative organisations can be an important tool to enhance the productivity and efficiency of smallholder farmers. Successful cooperative models together with training programs designed to enlighten farmers on the importance and tangible benefits of collective action should be used to enlarge participation in cooperative organisations. In addition, governments and development agencies should implement targeted investment and capacity building programs related to irrigation management, gender-sensitive awareness and development of the internal institutional mechanisms in cooperatives for the transfer of knowledge and mutual learning so that all members benefit from cooperatives.Originality/valueDespite the pervasive evidence of the impact of cooperatives on productivity and technical efficiency in the Asian region, this study is probably the first attempt in the crop sector in Mongolia. It provides a rigorous empirical analysis of the impact of agricultural cooperative membership on potato production and technical efficiency through a counterfactual design.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

The study identified the factors that cause variation in the level of efficiency in potato production. The study used household level cross sectional data collected in 2015/16 from 196 sample farmers selected by multistage sampling technique. For the data collection, a personally administered structured questionnaire was used. In the analyses, descriptive statistics, a stochastic frontier model (SFM) and a two-limit Tobit regression model were employed. Tobit model revealed that technical efficiency was positively and significantly affected by education, land tenure status, extension service, credit and soil fertility whereas variables such as sex of household head, age of household head, farm size and land fragmentation affected it negatively. Therefore the study suggested the need for policies to discourage land fragmentation and promote education, extension visits, access to credit and soil fertility for improvement in technical efficiency.

Potato microtubers plays important role in seed potato production technology as it has great advantage of storage, transport and mechanization due to their little size and reduced weight. Dormancy in potato microtubers is very important and storage conditions as well as size of microtubers influences the dormancy in microtubers. Increasing size of the micro-tuber resulted in significant increase in the viability and sprouting ability of microtubers with reduced durations of dormancy and weight loss at the end of storage. Small microtubers are more vulnerable to storage damage. The larger microtubers lost moisture content more slowly and retained firmness longer when stored at 40C. Development of dormancy during storage strongly affected by the storage condition especially the temperature regime, the presence of light and the relative humidity. The dormancy duration was linearly and inversely correlated with the length of storage. Storage containers and conditions are also important for microtuber storage. Endogenous hormones ABA, ethylene, cyokinin and gibberllic acid play a significant role in tuber dormancy regulation.Microtubers with thick diameter which have passed more times in dormancy and have better functionality than small microtubers with less time in dormancy. Growth regulators like gibberellic acid, thiourea, gibberllic acid + thiourea, randite and carbon disulphide plays significant role in dormancy breaking of microtubers.

AbstractTo contribute to the development of a novel cropping system for potato grown from greenhouse-derived seedlings from hybrid true potato seeds, planting density trials were carried out under normal Dutch agronomic conditions. For two consecutive years, 5-week-old seedlings of two experimental genotypes were transplanted into farmers’ potato production fields at two contrasting locations: a flat-bed system on sandy soil and a traditional ridge system on clay soil. Planting densities were 6.25, 12.5, 25, 50, 100 and 200 plants/m2 in the flat-bed system, and 3.125, 4.688, 6.25, 12.5, 25 and 50 plants/m2 in the ridge system. In general, increasing planting density of hybrid seedlings per area decreased tuber fresh weight per plant and reduced the number of tubers per plant. On a per hectare basis, an increased planting density resulted in increased total tuber yield and number of tubers up to very high densities, but finally both parameters levelled off. Highest total tuber yields harvested were 107 and 45 Mg/ha for the flat-bed and ridge system, respectively. On flat-beds, the optimal planting density for total yield was 50 plants/m2. On ridges, planting density interacted with year and genotype, resulting in an optimum planting density of 25 plants/m2 to reach the maximum total yield. Obtained yields in the commercial size classes Baby Baker (20 < size class ≤ 35 mm) and Seed Tubers (28 < size class ≤ 50 mm) were in general very high on the flat-beds, with a maximum Seed Tuber yield of 64 Mg/ha at 50 plants/m2. The current study showed that transplanted hybrid seedlings are feasible alternatives for seed-tuber-grown systems for certain potato outlets.

A trial was conducted at the FSRD site, Elenga and MLT site, Ghatail, Tangail during 2011-12 and 2012-13 to test the performance of the BARI developed USG applicator in boro rice and to find out the economic performance of the USG applicator in the farmers’ field. The BARI developed USG applicator was tested against the USG application by hand and the conventional method of granular urea application. The average higher grain yield (7.05 t ha-1 and 7.07 t ha-1) of two years were obtained from the plot of USG application with BARI applicator in the both locations, respectively   The highest gross return (120410 Tk. ha-1 & 20290 Tk. ha-1) and gross margin (64346 Tk. ha-1 and 62164 Tk. ha-1) during 1011-12 and 2012-13 were obtained from the plots treated with USG by BARI applicator at the FSRD site Elenga and MLT site Ghatail,  respectively. Field efficiency of BARI USG applicator and hand application was 0.12   hah-1 and 0.027 hah-1, respectively. BARI USG applicator saved time 77.65% compared to that of hand application of USG  in boro rice field. It also saved labor cost against the USG application by hand and reduces 33% urea over the granular urea application in conventional method.Bangladesh Agron. J. 2014, 17(2): 77-81
