ABSTRACT Mechanical damage of seeds due to harvest, handling and other process is an important factor that affects the quality and quaintly of seeds. Seed damage results in lower grain value, storability problem, and reduces seed germination and seedling vigor and subsequent yield of crops. The objectives were to determine the effect of different levels of zinc sulphate fertilization on the breakage susceptibility of three irrigated wheat varieties (Bahar, Shiraz and Pyshtaz). An experiment was conduct at the Experimental research station of Lorestan University, Iran. A factorial experiment was conducted with three replicates in a completely randomized block design (CRBD). Factors included three levels of zinc sulphate. Zinc sulphate treatments were combinations of three fertilization rates (0 - control, 25 and 50 kg/ha) at three replicates. The harvested seeds were subjected to impact energies of 0.05 and 0.1 J at constant moisture contents of 9.8, 15 and 20% using an impact test apparatus. The analysis of variance showed that wheat variety, fertilization level of zinc sulphate and moisture content significantly influenced breakage susceptibility of wheat seeds at the 1% probability level. Resistance to the breakage of wheat seeds for all varieties increased, as polynomial functions, with increase in the zinc sulphate rate. The average values of percentage breakage of seeds decreased from 37.07 to 27.80% as the fertilization level of zinc sulphate increased from 0 to 50 kg/ha. Bahar variety exhibited the highest resistance to breakage than other varieties. As the moisture content increased from 9.8 to 20% the percentage breakage of seeds decreased from 36.58 to 30.03%. Increasing the impact energy from 0.05 to 0.1 J caused an increase in the percentage breakage of seeds from 16.19 to 50.47%.

Abstract In order to determine the effects of different fertilization level of zinc sulphate and plant density on the breakage susceptibility of triticale seeds an experiment was conducted during 2011 growing season, at the experimental research station of Lorestan University, Iran. A factorial experiment was conducted with 3×3 treatments and three replications in a completely randomized block design (CRBD). Factors included three plant densities (200, 300 and 400 plants/m2) and three levels of zinc sulphate (0 - control, 40 and 60 kg/ha). The harvested seeds were then subjected to impact energies of 0.05 and 0.1 J at constant moisture content of 15% using an impact test apparatus. The analysis of variance showed that fertilization level of zinc sulphate (at the 1% probability level), plant density (at the 5% level) and interaction between two variables (at the 5% level) significantly influenced breakage susceptibility of triticale seeds. The average values of percentage breakage of seeds decreased from 32.592 to 16.9268% as the fertilization level of zinc sulphate increased from 0 to 60kg/ha. As the plant density increased from 200 to 400 plants/m2 the percentage breakage of seeds decreased from 27.942 to 21.350%. Increasing the impact energy from 0.05 to 0.1 J caused an increase in the percentage breakage of seeds from 14.07 to 36.9%.

The present study, set up in the growing season 2011-2012, was designed to obtain quantitative data on the occurrence of deoxynivalenol in wheat grain and the corresponding wheat dust. The field experiment consisted of a complete randomised block design with five wheat varieties sown on a field on which maize was grown in the previous season. The impact of the tillage method and the influence of the wheat variety resistance on the deoxynivalenol content of wheat and wheat dust were investigated. The accumulation of deoxynivalenol in wheat dust was confirmed and a sigmoidal relationship between the deoxynivalenol content in wheat dust versus wheat grain was determined. Deoxynivalenol reduction was obtained by ploughing and by sowing moderately resistant wheat varieties. As wheat dust provides equal results and solves the problem of heterogeneity during sampling of conventional wheat matrix, the sampling of wheat dust can be considered as a promising alternative.

Abstract Mechanical damage of seeds due to harvest, handling and other process is an important factor that affects the quality and quantity of seeds. Seed damage result in lower grain value, storability problem, and reduced seed germination and seedling vigor and subsequent yield of crops. The objective of this research was to determine the effects of moisture content and impact energy on the breakage susceptibility of wheat and triticale seeds. The experiments were conducted at five moisture contents of 7.5, 12, 17, 22 and 27% w.b. and at the impact energies of 0.05 and 0.1 J. The percentage of breakage of both wheat and triticale seeds increased as impact energy increased. The analysis of variance showed that there was a significant difference between breakage susceptibility of wheat and triticale seeds at the 1% probability level. Triticale seeds had more breakage than wheat seeds. For both wheat and triticale seeds as the moisture content of the seeds increased, the amount of the percentage breakage of seeds decreased as a polynomial. The average values of percentage breakage of wheat seeds decreased from 43.81 to 19.88% as the moisture content increased from 7.5 to 27%. Over this same moisture content range the percentage breakage of triticale seeds varied from 81.34 to 37.77%. Below the moisture contents of 17% for the wheat and 22% for the triticale the percentage breakage of seeds increased dramatically.

Background: The present investigation is an attempt to study the effect of different harvesting and threshing methods on germination and seedling vigour of dhaincha. The use of a combine harvester to harvest dhaincha will be an effective alternative method that has not been widely tried. However, work on different methods of harvesting and threshing of dhaincha is limited. Hence, a study was conducted to evaluate the impact of various harvesting and threshing methods on germination and seedling vigour of dhaincha. Methods: This study was conducted at Anbil Dharmalingam Agricultural College and Research Institute, TNAU, Tiruchirappalli, Tamil Nadu. The dhaincha crop was harvested and threshed using four different methods viz., manual harvesting and manual threshing, manual harvesting and threshing by tractor treading, manual harvesting and mechanical threshing and harvesting and threshing by combine harvester. The resultant seeds were tested for mechanical damage and germination potential. The experiment was laid in completely randomized block design. Germination was tested by roll towel method using 100 seeds in four replications. Germination percentage, root and shoot length were measured in seven days after sowing from ten randomly selected seedlings in each replication. For the estimation of dry matter production, ten seedlings were selected at random and kept in a hot air oven maintained at 85oC for 24 hours after measuring their root and shoot length and vigour index was calculated. Mechanical damage to seeds was observed by ferric chloride test. Seed recovery per cent was calculated based on the 100 kgs of dhaincha seeds were cleaned and graded treatment wise using cleaner cum grader and the seeds retained on the bottom sieve were weighed and expressed as per cent of total quantity of seed. Result: The results revealed that the significant difference was found among the different harvesting and threshing methods. The seeds harvested and threshed by manual method recorded 85 per cent germination followed by seeds harvested manually and threshed by mechanical threshing (84 per cent) and seeds harvested manually and threshed by tractor treading (80.5 per cent). The lowest germination of 80.0 per cent was recorded by combine harvesting. From this study, it could be inferred that combine harvester is a modern method for harvesting of dhaincha that saves time and labour when compared to all other methods.

AbstractMechanical damage of seeds due to harvest, handling and other process is an important factor that affects the quality and quaintly of seeds. The objective of this research was to determine the effects of moisture content and the impact energy on the breakage susceptibility of vetch seeds. The experiments were conducted at moisture contents of 7.57 to 25% (wet basis) and at the impact energies of 0.1, 0.2 and 0.3 J, using an impact damage assessment device. The results showed that impact energy, moisture content, and the interaction effects of these two variables significantly influenced the percentage breakage in vetch seeds (p<0.01). Increasing the impact energy from 0.1 to 0.3 J caused a significant increase in the mean values of seeds breakage from 41.69 to 78.67%. It was found that the relation between vetch seeds moisture content and seeds breakage was non-linear, and the extent of damaged seeds decreased significantlyas a polynomial (from 92.47 to 33.56%) with increasing moisture (from 7.57 to 17.5%) and reached a minimum at moisture level of about 17.5%. Further increase in seed moisture, however, caused an increase in the amount of seeds breakage. Mathematical relationships composed of seed moisture content and impact energy, were developed for accurately description the percentage breakage of vetch seeds under impact loading. It was found that the models have provided satisfactory results over the whole set of values for the dependent variable.

Abstract Dual-purpose wheat (Triticum aestivum L.) systems increase farm sustainability by diversifying on-farm income. While these systems are common in the Southern Great Plains of the United States, they are not often utilized in the Southeast. This study aimed to evaluate pre- and post-grazing herbage mass (HM) of four winter wheat varieties managed under a dual-purpose grazing and grain production system. The winter wheat varieties evaluated were generic feed-type wheat (mixed variety, Feed), seed-type wheat (‘GA Gore’) and two forage-type varieties, ‘AGS 2024’ (AGS) and ‘Pioneer 26R41’ (Pioneer). The experiment was a completely randomized block design with n = 4. Each plot was randomly assigned either as no-grazing (CON) or grazing (GF2). Plots were grazed with cow-calf pairs that were fasted 24 h before each grazing event. Grazing was considered complete when the average stubble height was 10 cm. Herbage mass was determined using three 0.1m2-quadrats per plot and clipping to a 10 cm stubble height before (PreG) and after (PostG) each grazing event. Forage samples were then dried at 45°C for 72 h. Data were analyzed using PROC GLIMMIX of SAS (SAS Inst., Cary, NC). Differences were declared at P &lt; 0.05. Initial HM was greater for PreG than PostG (883 and 615 kg/ha, respectively; P &lt; 0.01). Prior to grazing, AGS (1204 kg/ha) was greater (P &lt; 0.02) than all other varieties. Pre-grazing, there were no differences among the other varieties (776 kg/ha; P &gt; 0.14). Post-grazing, AGS had a greater HM than Seed (788 and 391 ka/ha, respectively; P = 0.04), while all other varieties were intermediate (642 kg/ha). Herbage mass was affected by grazing frequency with CON being greater (P &lt; 0.01) than GF2 (993 and 691 kg/ha, respectively). These results indicate that both wheat variety and grazing treatment had an effect on dual-purpose wheat herbage mass.
