A very important breakthrough in saffron cultivation and production was achieved by Sher-e- Kashmir University of Agricultural Sciences and Technology of Kashmir (SKUAST-K) when the university developed a production system module in saffron which brought substantial increase in productivity of saffron during last two decades. The adoption of the technology was observed to have a very significant impact on the social dynamics of the saffron producing region demanding its ex-ante and ex-post evaluation vis a vis non adopters of the technology. With this in mind consumer surplus model and propensity score matching methods were employed on a sample of 447 respondents of which 286 were adopters and 161 non-adopters (control group) drawn from a population of 753 saffron growers in the saffron belt of Jammu and Kashmir producing 99% of the total saffron production in the country. The results revealed that average productivity of the spice increased from 2.57 kg.ha-1 to 6.05 kg.ha-1, with 1-2 kg.ha-1 in the first year to 10-12 kg.ha-1 in fourth year against control group, however, the investment cost estimates recorded increase of 5.9% under ex-ante and 13.6% under ex-post evaluation while adopting new technology, which however, got compensated through realizing higher productivity and increased employment to the tune of 40.6 and 28.3 per cent man-days/ha respectively under ex-ante and ex-post evaluation. The results further revealed, NPV, BCR, IRR of Rs. 399 crores, 110, 154% against Rs.249 crores, 69, 134% respectively under ex-ante and ex-post evaluation of the technology.

The study aims to measure the comparative and competitive advantage of red meat production in the Kokjali region of Nineveh through some measures derived from the policy analysis matrix. The study relied on the primary data collected through the questionnaire form for a random sample of (100) fields included (5610) imported calves in the Kokjali district of Nineveh Governorate for the production year 2018. The sample was distributed into three categories according to the number of calves. The sample was divided into three categories, according to the number of calves, the first category of fields contains 25-49 calves and their number reached 35 fields, and the second category represents fields that contain 50-74 Calf has reached 48 fields, and the third category represents the fields that contain 75 calves or more and reached 17 fields. The results of the study indicated that the measures of protection and indicators of comparative advantage showed that there is no government support to protect red meat production in the domestic market for the year 2018 and this is clear from the nominal protection coefficient of the outputs 0.263. The same is the case with the nominal protection coefficient of inputs 1.212, as the results of the study showed that there is no government support. In addition, the measure of the special costs ratio indicated that the red meat product system has international competitiveness 0.004. Finally, the value of the local resource cost factor 0.131 indicated that the Kokceli area has a comparative and competitive advantage for the production of red meat, as the coefficient appeared to be less than the correct one.

Breeding, preserving, and successfully rearing young animals resistant to various environmental influences is one of the main parameters of effective livestock management. The study aimed to study the indicators of natural resistance and the growth rate of calves under the influence of dietary supplements. The studies were carried out on four groups of black-and-white calves, 10 heads each, at the age of 2-5 months. The dairy calves of the control group were fed according to the ration adopted on the farm (basic ration, including cereal-legume hay, whole milk, milk replacer, concentrates, chalk, salt). In addition to the main diet, the animals of the experimental groups were given a dietary supplement. At 2-3, 3-4, and 4-5, months of age, calves were given 12-23, 19-38, and 23-47 g.head-1 of dietary supplement per day, respectively. The article deals with the effect of a forest biomass supplement on the morphophysiological parameters of calves. Biochemical blood analysis and the features of metabolic processes in the bodies of animals are studied. The results indicated that the use of a dietary supplement at a dosage of 30 g/head of cattle per day contributes to the highest increase (9.9%) in live weight gain of experimental animals and an improvement in natural resistance parameters (bactericidal activity of blood serum, phagocytic activity of neutrophils). Based on the data of biochemical and haematological blood tests, the authors conclude that the inclusion of a dietary supplement in the diet of calves has a positive effect on the indices of natural resistance and the course of nitrogen metabolism.

Three tests of phylogenetic including likelihood-joining tree, neighbour-joining tree, and minimum evolution tree have been used based on sox3 gene. Phylogenetic analysis was used to detect the genetic affinity and common ancestors for selected species that belong to the same or different families. This study showed the most appropriate methods for testing the genetic affinity among species and the methodology of each test according to the requirement of molecular applications. Secondary RNA predicted structure and minimum free energy were also included in this study because of their contribution to the detection of the orthologous gene and variance in RNA folding among species related to the different families. The genetic distance in the studied populations was calculated to know the most appropriate way to find out the genetic similarity among the studied species. The low distance-variance value of each group indicated significant genetic affinity among the species of the same family, this result is more consistent with the test of maximum-likelihood tree indicating the validity of this test to measure the genetic affinity among species that have common ancestors.

This study was conducted in the animal field of the Al-Kafeel Company from November 2019 till May 2020 to investigate the possible association between growth hormone (GH) and thyroxine (T4) with the growth traits in Awassi and Karakul sheep. The total number of animals which used in the study was 60 lambs, 28 (13 males and 15 females) from Karakul and 32 (18 males and 14 females) from Awassi. Blood samples were collected at birth, weaning, and six months of age, and both GH and T4 concentrations were measured. Results showed higher values of T4 for Karakul as compared with Awassi at birth and weaning. Karakul breed was also exhibited significantly higher values of GH over Awassi breed only at weaning, while, no significant differences were observed at birth and six months of age. Karakul lambs showed higher weights as compared with Awassi lambs at all studied periods. A highly significant (p < 0.01) positive correlation was observed between T4 concentration and the weight of lambs at most studied periods. Whereas, GH did not exhibit any correlation with growth traits measured in both breeds. The elevated T4 might be one of the reasons for superiority of Karakul over Awassi breed in live body weights. This high correlation between T4 and growth traits could be used in the early selection of lambs to improve the weights of sheep at marketing.

In order to investigate the possibility for in in vitro fast regeneration of Dianthus caryophyllus, different concentrations of Kinetin (Kin), 2,4-Dichlorophenoxy Acetic Acid (2,4-D) had been tested for induction of callus by leaves and stems explant using Murashige and Skoog (MS) medium. After two months in culture, response callus in the induction rate, fresh and dry weight, texture and color were evaluated. MS medium that contained 4.5 mg.L-1 2, 4-D was suitable for callus induction with leaf explants. The combination of 0.4 mg.L-1 Kin and 2.0 mg.L-1 2, 4-D also demonstrated a wonderful induction of callus on stem explants. In addition to the culture medium complemented by Kin and 2, 4-D, the influence of Zeatin at various concentrations (0.0, 0.4, 0.8 or 1.0 mg.L-1) was assessed. In MS medium that contained 0.4 mg.L-1 Kin+ 2.0 mg.L-1 2,4-D+ 1.0 mg.L-1 Zeatin, rapid callus induction and also more callus proliferation from stem explants were detected. Results indicate on callus induction that, Zeatin was more successful than Kin or 2, 4-D, but other combinations directly developed a shoot. Callus obtained from stems explant was friable, white and yellow, while callus from leaf explants was green.

The research aims to compare the performance (PC) and specific energy consumption (Spc.) of the hammer mill when using the T-hammer against the (traditional) rectangular hammer. A homemade mill with four hammers was used in experiment. 36 treatments: 2 hammer shape x 3 impact area (840, 720 and 960 mm2) x 2 feeding rates (1500 and 3000 g min-1) x 3 replicates, with completely random design. The results showed that there was no significant effect of hammer shape on PC at the feed rate of 3000 g min-1, while there was an effect at the rate of 1500 g min-1. An effect was also found for the impact area on the PC at both feeding rates and on Spc., as an inverse relationship appeared between the impact area and mill productivity at the feed rate 1500 g min-1. The area of 720 mm2 surpassed the area 480 and 960 mm2 at the rate of feeding 3000 g min-1, as it recorded 1215.65 g min-1 compared to 950.65 and 882.65 g min-1, respectively. There is effect of feeding rate on PC and Spc. The traditional hammer is recommended for simplicity of design, manufacture and performance at high feed rates compared to the T-shaped hammer.
该研究旨在比较锤式磨机在使用t型锤和(传统)矩形锤时的性能(PC)和比能耗(Spc)。用自制的四锤磨机进行了试验。36个处理:2个锤形× 3个冲击面积(840、720和960 mm2) × 2个投喂率(1500和3000 g min-1) × 3个完全随机设计的重复。结果表明，锤头形状对PC的影响在3000 g min-1时不显著，而在1500 g min-1时有影响。还发现了在进料速率和Spc下对PC的影响面积。，当进给量为1500 g min-1时，冲击面积与磨机生产率呈反比关系。以投喂3000 g min-1的速度，720 mm2的面积超过480和960 mm2，分别为1215.65 g min-1，而950.65和882.65 g min-1。喂料速率对PC和Spc有影响。与t形锤相比，传统锤在高进给速率下的设计、制造和性能简单，因此推荐使用传统锤。

This study aims to prepper stable thermodynamically dilutable nanoemulsion formulation of Beauveria bassiana with the lowest surfactant concentration that could improve its solubility stability. Formulations were prepared from oil in the water nanoemulsion region of phase diagrams subjected to thermodynamic stability tests. We found propanetriol was the highest germination rate at 5% and 10% concentration, 46.66 and 53.33%, respectively. Castor oil achieved a 43.00 germination rate at 1%. Tween 80 gave 54.33 % germination rate at 10%. While Tween 20 showed a 48 % germination rate at 5%. At the concentration, 1% Term 1284 gave 43.33% rate germination. Nanoemulsion composed of propanetriol and nonionic surfactants, with a mean particle size ranging from 25.08 to 75.35 nm, was formulated for various concentrations of the oils and surfactants. Water in oil emulsion was prepared using propanetriol oil, Tween 20, Tween 80, Term 1284, and water. Nanoemulsion of 25.08, 33.75, and 75.35 nm size was obtained at a 45: 15 % ratio of oil and surfactant, and it was found to be stable. The larger droplet size 75.35 nm of formulation Tween 20 and the smaller size was 25.08 nm in the formulation of Term 1284. The higher viscosity value was 16 mPas of formulation Tween 80, and the lowest value was 7.80 in the formulation of Term 1284. To demonstrate the possible employment of these systems, they were used to formulate a nanoformulation pesticide.
