Genotype-environment interaction (GEI) is very important for breeders. It is considered a complicated issue in breeding programs to obtain stable and high-yielding genotypes to release new genotypes. This study was conducted to achieve a stable high-yielding genotype that is adaptive to climatic conditions of potato-producing regions in Iran. A total of 20 potato breeding lines along with five commercial varieties (Savalan, Agria, Caesar, Luta and Satina) were evaluated in a randomized complete block design with three replicates in the Agricultural Research and Natural Resources Stations of five location (Ardabil, Razavi Khorasan, Karaj, Isfahan and Hamadan) in Iran, for two years (2016 and 2017). Combined ANOVA of yield data for studied genotypes and environments indicates significant differences among potato genotypes, environments, and GE interaction was significant. Thus, the AMMI method and its parameters were used to analyze yield stability. The results indicated that only four interaction principal components were significant (P<0.01), which accounted for 81.2% of the GEI sum of squares. Based on type 1 parameters (SIPC1, FA1, Za1, Dz1, EV1, and Da1), genotypes G7, G10, G14, G20 and G24 were identified as to be stable. Moreover, according to the results of type 2, 3 and 4 parameters, genotypes G2, G6, G7, G14, G15 and G20, as well as cultivars Agria (G24) and Luta (G23), were found to be stable. Genotypes G6, G7, G14, G15, G20, and G24 were stable according to the ASV parameter, and genotypes G6 and G7 were stable based on the MASV parameter. Amongst the stable genotypes identified by the AMMI parameters, while genotype G6 was high-yielding, G14 and G24 (Agria) were moderate-yielding.

ABSTRACT This paper sought to evaluate the economic impact of the Cotton YIELD Programme on crop income of smallholder cotton farmers in Zambia. Specifically, the study sought to (a) identify factors that influence smallholder cotton farmer’ participation in the programme and (b) determine whether the Cotton YIELD Programme has increased the income of smallholder cotton farmers in Zambia. The study utilized pooled cross-section data of 300 cotton farmers, collected from two households survey (2005 and 2015) in Mumbwa district of Zambia. The Double Difference model combined with Propensity Score Matching methods were employed in the analysis. Results show that participation in the programme is positively driven by education, farm size, membership, access to credit, ownership of animal traction and media. However, distance to extension agents and market outlets negatively influence participation. Furthermore, the study found that the Cotton YIELD Programme has significantly increased crop income of smallholder cotton farmers by 38.1 percent.

This study was carried out to determine the effects on growth performance of diets based on hazelnut meal 30% supplemented with different rates of phytase enzymes in Siberian sturgeon (Acipenser baerii) (initial weight, 960.23 ± 0.55 g). The experimental diets were consisted of with no added enzyme in the control group (G1) and diets supplemented with 0.25 g/kg (G2), 0.50 g/kg (G3) and 1.00 g/kg (G4) phytase enzyme, respectively. Experiment groups were performed in 3 replicates and carried on with 90 days. As a result of the research, it was determined that the addition of phytase enzyme in diets had a positive effect on the growth with weight gain (WG, g), specific growth rate (SGR, %), feed conversion ratio (FCR) and protein efficiency ratio (PER). The growth performance of all phytase enzyme supplemented groups were found to be more successful than the control group (P<0.05). The G4 enzyme group was found to be statistically better than the others (P<0.05). In terms of digestibility effect of enzyme added groups, the highest total digestion rate (77.14 ± 0.07 %) was obtained in the G4 enzyme group and the lowest total digestibility (74.32 ± 0.02%) was obtained in the G1.

The objective in study was to evaluate the performance of a vacuum single-seed planter in field conditions to optimize some operating parameters in maize production. The target seed spacing (effect of operational speed of the seed disc) and tractor forward speed were evaluated by examining the mean seed spacing, coefficient of precision in spacing, miss index, multiple index, quality of feed index, sowing depth, deviation from row (inter-row spacing), mean emergence time, emergence rate index and percentage emergence. A vacuum single-seed planter was used for sowing at three forward speeds (4.0, 5.4 and 7.9 km h-1) and five target seed spacings (102, 147, 195, 247 and 309 mm). The point dropped in furrow of seed, depth of seed placement, emergence rate and three indices of uniformity in seed spacing and precision coefficients of sowing quality were determined. The planter performed the best performance at the lowest forward speed and the highest target seed spacing. Increasing the forward speed resulted in a shallower sowing depth. The desired planting depth was also obtained at 4.0 km h-1 in all plots. Increasing target seed spacing increased the emergence rate by about 35%, while increasing forward speed decreased the emergence rate by 10%. Sowing at 4.0 km h-1 resulted in the lowest miss, multiple and precision indices (5.1% 2.9%, and 15.3%, respectively), and a quality of feed index as high as 92% was obtained in similar conditions. The results indicated that, with single-seed planters, success may be achieved in a conventional tillage maize production system at a target seed spacing of less than 100 mm and tractor forward speeds of less than 7.9 km h-1, thus satisfying farmers who carry out maize sowing by conventional tillage.
本研究的目的是评价真空单种播种机在田间条件下的性能，以优化玉米生产中的一些操作参数。通过考察平均种间距、间距精度系数、脱粒指数、倍数指数、饲料质量指数、播种深度、行距(行距)偏差、平均出苗期、出苗率指数和出苗率，评价目标种间距(播盘运行速度的影响)和拖拉机前进速度。采用真空单种播种机，以3种前进速度(4.0、5.4和7.9 km h-1)和5种目标播种间距(102、147、195、247和309 mm)播种。测定了种沟落点、播种深度、出苗率、种距均匀度3个指标和播种质量精度系数。播种机在最低前进速度和最高目标种子间距时表现最佳。增加前进速度导致播种深度变浅。在4.0 km h-1条件下，所有样地均获得理想种植深度。增加目标种子间距可使出苗率提高约35%，而增加前进速度可使出苗率降低10%。在4.0 km h-1播种条件下，脱靶率、倍数指数和精度指数最低(分别为5.1%、2.9%和15.3%)，饲料质量指数高达92%。结果表明，单种子播种机在常规耕作玉米生产系统中，目标种距小于100 mm，拖拉机前进速度小于7.9 km h-1时，可以取得成功，从而满足采用常规耕作方式进行玉米播种的农民。

The aim of this study was to investigate the effect of addition of different boron sources (ulexide, colemanite, etibor-48) to diet containing low Ca, P on bone parameters and bone strength in weaned lambs. 50 Akkaraman single male lambs weaned at 2.5 months of age were used. Lambs were divided into 5 groups. Groups were; positive control, negative control, supplementation with colemanite, supplementation with etibor-48, supplementation with ulexide. Roughage and concentrated feed was given twice in day. At the end of 90 days, 6 animals from each group were slaughtered. The weight, dry weight, length, width and ash levels of the femoral and tibial bones were significantly increased in added boron (B) sources groups compared to negative control. With the supplementation of the colemanite and ulexide to diets, the femoral and tibial Ca content was higher compared to negative control. The P content in the femoral bone increased in groups added of all boron sources than that in negative control, also in tibial P content in the colemanite and ulexide groups increased compared to negative control. The supplemantation of all B sources had improved B levels and breaking strength of bones compared to controls.

Turkey has long been the leader in oriental tobacco production in the world. Tobacco is the main income source in most production areas of Turkey. The need for standard cultivars that can meet maximum yield and quality conditions have been increasing. The aim of the present study was to determine cultivar candidates with superior characteristics for Basma type oriental tobacco production areas. Field trials were carried out in Bafra District of Samsun Province, the district with most tobacco production in Mid-Black Sea Region, and Evciler, Karayaka and Gumushacikoy locations where Basma type oriental tobaccos are produced. Experimental design was randomized complete blocks with three replications. The study material consisted of 21 lines selected by morphological characteristics and identified by DNA fingerprinting analysis and four standard cultivars/lines. Chemical analyses were carried out using HPLC method. Stability of genotypes were determined for dried leaf yield, quality index, nicotine and sugar content using regression coefficient (bi), regression constant (a), determination coefficient (r2), coefficient of variation (CV) and deviation from regression (S2d) parameters. Based on their performance for stability parameters and other traits, ERB-6, ERB-7, ERB-11, ERB-13, ERB-16, ERB-18, ERB-21 and ERB-30 lines were prominent ones, and it was concluded that our future studies should be continued using these lines. In conclusion, superior lines and cultivar candidates demanded by growers and sector for production areas of Basma type oriental tobacco were determined.
