Determination of flower microphenology for selecting the suitable pollinizer for sour cherry cultivars is of significant importance. In order to study the flower microphenology of Hungarian sour cherry (Bőtermő, Érdi jubileum and Cigány) cultivars in Mashhad climatic conditions, an experiment was conducted in I998. 1999, 2005 and 2006, using a completely randomized design with ten replications. The phenological stages were determined from before opening up to browning phase of stigma. Duration of pollen shedding, stigma receptivity and climatic factors were measured. The relative time of flowering between cultivars varied from year to year. The data indicate, the thermal variation strongly contributes to significant differences in duration of stigma viability, although there wasn't a significant difference between cultivars in anther dehiscence period. Phenological stages of flowers are highly affected by meteorological factors in various years.

Apple fruits are subjected to different loading damage from harvesting to supermarket shelf. Bruising has been attracted many researchers as one of the most important damage criteria. In this research, the effects of some factors such as counter-face material, drop height and linear velocity of apples (conveyor speed) were investigated. Influence of these factors on bruising of ?Golab-Kohanz? variety was analyzed by a Completely Randomized Design (CRD) with factorial test at three levels of drop height (10, 20 and 30 cm), conveyor speed (0.05, 0.1 and 0.15 ms- 1) and four counter-face materials (wood, steel, plastic and cardboard). Tests were conducted at three replications with 108 treatments. Analysis of variance results showed that the effects of drop height and counter-face material on bruising area at 1% level was significant while bruising volume only affected by contact surface material (P<0.01). Mean comparison test indicated that there was no significant difference among levels of conveyor speed on the area and volume bruising. Also, there was no significant difference among levels of drop height on volume bruising while it was significant on the area bruising. Steel and wooden material had no significant effect on the area and volume bruising but their differences with plastic and cardboard were significant. Therefore, drop height and counter-face material must be considered in designing the apple processing systems.

Determination of crude fat content (ether extract) using a separate Soxhlet method requires an extraction time of 4 to 6 hours to achieve 5-6 circulation for 1 sample of material. Given the fact that the analysis and extraction time are not time efficient, therefore an alternative method is needed with good accuracy and faster testing time. One alternative is the single-extractor Soxhlet method.  The aims of  this study were to evaluate the comparison of crude fat extraction results in the separated Soxhlet method and the Soxhlet method in one extractor for several feed ingredients. For the fat testing, this study used two methods, namely the separate method and the Soxhlet method of testing single extractor. The experiments were done by a completely randomized design with 2 treatments and 3 replications. The data was analyzed using the Student T-test. The results showed that the separate Soxhlet method and the single extractor Soxhlet method had no significant difference to the crude fat content of the concentrate feed ingredients with T> 0.05. The use of single extractor Soxhlet showed significant result with T< 0.01 which lower ​​than the separate Soxhlet method in forage samples on the crude fat concentration. Given the outcomes, the use of single extractor Soxhlet is more efficient than the separate Soxhlet method in terms of analysis time of a large number of samples.

Aim: The present study was aimed to find out the robust hybrid during summer season under temperate climatic conditions. Study Design: Completely Randomized Design (CRD). Place and Duration of Study: College of Temperate Sericulture (CoTS) Mirgund, Sher-e-Kashmir University of Agricultural Sciences and Technology, of Kashmir (SKUAST-K), in the year 2014. Methodology: The disease free layings (dfl’s) of the selected hybrids viz., SK31× SK13, SK6 × SK13 and CSR18× CSR19 were obtained from the Germplasm Bank maintained at College of Temperate Sericulture (CoTS) Mirgund, Sher-e-Kashmir University of Agricultural Sciences and Technology, of Kashmir (SKUAST-K). Thesedfl’s were incubated, brushed and reared up to 3rd instar en masse following the standard rearing procedure. Just after 3rdmoult, 3 replications of 100 larvae in each treatment were maintained. Cocoon and post cocoon parameters viz, pupation rate, single cocoon weight, single shell weight, shell ratio, raw silk, denier and leaf cocoon ratio were calculated and recorded during the course of experimentation. Results: No significant difference was recorded in pupation rate among the hybrids. H1 hybrid was found significantly superior over H2 and H3 for single cocoon and shell weight with mean value as 1.957 and 0.406 respectively. On the other hand influence of hybrids over shell ratio remained non significant. The performance of silkworm hybrids with respect to raw silk was recorded higher in H1 (17.98%) followed by H2 (17.96%) and H3 (17.93%), while the fine denier of 2.86 d was reported in H3 followed by H1 (2.94d) and H2 (3.01d). Leaf cocoon ratio was recorded lower in H1with mean value as 15.16 /100 dfl’s. Conclusion: Significant differences among the hybrids were observed, but no hybrid performed better in all traits studied, however in maximum traits SK31× SK13, seems to be superior to the other two studied hybrids.

A factorial experiment was conducted with a completely randomized design to evaluate the effects of planting date and density on calendula herbs and peppermint. It had 3 replicates and was done in Khosroshahr research farm, Tabriz in 2006. Under studied factors were: 3 planting dates (10 May, 25 May and 10 June) in 4 densities (25, 35, 45, 55) of the plant in square meters. The results of variance a nalysis showed that there was 1% probability significant difference between the effects of planting date and bush density on the leave number, bush height and the bush dry weight. But the mutual effect of the plant date in mentioned traits density was insignificant. Regarding the traits mean comparison, the total maximum dry weight was about the 55 bush density in mm. Also, the bush high density in mm causes the bush growth and its mass reduction. When there is the density grain, the flower number will increase due to bush grain in surface unit. Overall, we can conclude that 10 June planting and 45 bush density in mm is the most suitable items and results in favored production with high essence for these crops.

Abstract Mangalica pigs are a popular niche breed given their reputation for superior quality pork. However, growth and carcass parameters for this breed are poorly documented. Our objective was to better characterize optimal harvest weights for the Mangalica breed. To accomplish this, a growth trial was conducted whereby pigs (n=56) were randomly distributed across stratified harvest weights (50, 57, 68, 82, 93, 102, 127 kg) in a completely randomized design. Pigs were fed standard finisher rations with individual daily feed intakes and weekly body weights recorded for all animals. At 24h postmortem, carcasses were split and ribbed with marbling and loin eye area (LEA) measured at the 10th rib. Primal cuts were fabricated and individually weighed. Fat back was separated from the loin and weighed. As expected, live weight significantly increased across weight class (P &lt; 0.0001). ADG was similar across classes up to 82 kg live weight before steadily declining with increasing weight class (P &lt; 0.0025). Likewise, feed efficiency did not differ between classes until weights heavier than 82 kg (P &lt; 0.03). LEA significantly increased by class up to 82 kg and then plateaued as harvest weight increased further (P &lt; 0.003). Marbling score significantly increased with increasing weight class up to 102 kg where they then plateaued (p &lt; 0.04). Fat back dramatically increased across all weight classes (p &lt; 0.0001) despite negligible increases in LEA or marbling after 102 kg. Primal cut weights for the ham (P &lt; 0.0001), loin (P &lt; 0.0001), Boston butt (P &lt; 0.0001), shoulder (P &lt; 0.0001), and belly (P &lt; 0.0001) all significantly increased with increasing live weight. These data suggest an optimal harvest weight occurs between 82 to 102 kg while offering little objective justification for the current practice of harvesting Mangalica pigs at much heavier live weights.

ABSTRACT Reports of failure in the chemical control of wheat yellow leaf spot led to determination of the sensitivity of Drechslera tritici-repentis (Dtr) to the fungicides quinone outside inhibitors (QoIs) and demethylation inhibitors (DMIs). The IC50 was obtained for strobilurins (azoxystrobin, kresoxim-methyl, picoxystrobin and pyraclostrobin) and for triazoles (cyproconazole, epoxiconazole, propiconazole, prothioconazole and tebuconazole), using five Dtr isolates. Seven concentrations of the fungicides were tested in the bioassay: 0.00; 0.01; 0.10; 1.00; 10:00 and 20.00 and 40.00 mg/L active ingredient (a.i.). Assays consisted of completely randomized design and four replicates. Each experiment was performed twice, using the average of the two tests for statistical analysis. The percentage inhibition data for conidial germination (QoIs) and for mycelial growth (DMIs) were subjected to logarithmic regression analysis, calculating the 50% inhibitory concentration (IC50) based on the generated equation. There was a reduction in the sensitivity of Dtr isolates to strobilurins. IC50 values ranged from 0.58 to > 40.00 mg/L. The lowest sensitivity of isolates was detected for azoxystrobin, kresoxim-methyl, picoxystrobin and trifloxystrobin. Pyraclostrobin was most efficient, showing IC50 between 0.58 and 1.03 mg/L. The IC50 ranged from 0.35 to 1.37 mg/L for epoxiconazole, from 0.49 to 1.28 mg/L for propiconazole and from 1.41 to 2.34 mg/L for tebuconazole. Prothioconazole was most potent, showing IC50 between 0.09 and 0.21 mg/L. The hypothesis that the control failure can be attributed to the reduced Dtr sensitivity to the fungicides QoIs and DMIs was confirmed.

ABSTRACT This study aimed to understand the influence of sowing depth and the amount of sugarcane straw on the emergence of weed species Luffa aegyptiaca Miller (Cucurbitaceae); Mucuna aterrima Piper & Tracy (Fabaceae - Leguminosae) and Ricinus communis (Euphorbiaceae). A completely randomized design with a 5 x 4 x 3 factorial layout with four replications was used, at five sowing depths (0, 2, 4, 8 and 10 cm), four different amounts of sugarcane straw (0, 5, 10 and 15 t ha-1) and three different evaluation periods (7, 14 and 21 days after sowing). After sowing, different amounts of sugarcane straw (0, 5, 10 and 15 t ha-1) were deposited on soil. Seedling emergence was analyzed at 7, 14 and 21 days after sowing, counting the number of seedlings that had emerged. At the end of the trial, weed height (cm), leaf area (cm2) and shoot dry mass (g) were measured. In relation to emergence ability, studied species presented different responses according to sowing depth and to the amount of sugarcane straw deposited on the soil. For the L.aegyptiacaand M.aterrima, no significant difference was observed in the interaction between depth and sugarcane straw, showing the adaptation of these species to no-burn sugarcane system. For R.communis, seeds placed at 0 cm of sugar cane straw depth were observed to favor the emergence of seedlings.
