In this research, the goal of review was summarizing the current knowledge of the methods available to assess in vitro quality of frozen-thawed bovine spermatozoa also, a review on animal’s semen characteristics: fertility, reproduction and development after AI with that semen. Artificial insemination (AI) is the first generation reproductive biotechnology that has made a deep contribution to the genetics improvement in several animals. A fertile ejaculate must meet certain semen characteristics quality standards, such as: normal morphology, active energy metabolism, progressive motility, structural integrity and functionality of the membrane, penetration capacity and optimum transfer of genetic material. The percentage of total motile spermatozoa in normal canine ejaculates is between 70 to 90%. By the way, there are a lot of parameters that able to change on the composition and structure of various sperm plasma member domains, such as change temperature and sensitive to any theirs environments in vivo and vitro (tropical climates), season also nutrition. Computer-assisted semen analysis (CASA) is primarily used to obtain accurate and objective kinetic sperm measurements that gives extensive information about the kinetic property of the ejaculate based on measurements of the individual sperm cells.

This study was conducted to evaluate the effect of different methods of seed pre-treatment on germination of two indigenous tree species, Sweet dattock and Indian jujube (Detarium microcarpum and Ziziphus mauritiana). The experiment is carried out at the Tree Seedlings Nursery of Faculty of Agriculture, Kebbi State University of Science and Technology, Aleiro. Treatments consisted of Boiled water (100ºC) for 10 minutes, 20 minutes and 30 minutes; three levels of diluted sulphuric acid (H2S04) soaking time for 10minutes, 20 minutes and 30 minutes; Seed scarification and control. The treatments were arranged in Completely Randomized Design (CRD) with three replications per treatment. Results revealed that the seed of Sweet dattock (Detarium microcarpum) soaked in hot water at 1000 C for 30 minutes exhibited the best germination percentage (100.00±0.00) within four (96 hours) days. This is followed by hot water treatment for 10 minutes and sulphuric acid treatment for 20 minutes which gave the same germination percentage of 93.33±11.54 within 4 (96 hours) days. The seeds under control treatment gave the least germination percentage of 86.67±11.54 and took a longer period to germinate (eleven days.) Indian jujube (Ziziphus maurtiana) seeds on the other hand, gave the highest germination percentage (93.33±5.77) with scarification, followed by soaking in hot water for 30minutes (46.57±11.54), while the lowest germination percentage was recorded for seeds in the untreated control (3.33±5.77). Based on the result, pre-treatment of Sweet dattock (Detarium microcarpum) seed with hot water at 1000 C for 30 minutes and scarification of Indian jujube (Ziziphus maurtiana) seed is recommended for effective germination.

The main purpose of the study was to evaluate farmers socio-economic status, attitude and relationship among them towards organic farming. The study was conducted in five upazilas of Chapainawabganj district in Bangladesh. A simple random sampling technique was used to select 40 respondents. Attitude of respondents toward organic farming was measured with twenty statements using five point likert type scales. To explore the relationship between the concerned variables correlation coefficient (r) was computed. Descriptive statistics were used to describe the variables. Majority of the respondents were male (90%), average age was 44 years. 45% respondents were illiterate, had average 4 years of farming experience. Majority of the respondents (80%) had positive attitude towards organic farming. Relatives and Extension Agents were found as the main information source of organic farming for most of the respondents. Cosmopoliteness and Extension contact had positive and significant relationship with their attitude (.461 and .377 respectively). It was concluded that farmers were knowledgeable about organic farming and also had favourable attitude toward its practices. Efforts should therefore be made to promote and increase the practice of organic farming. By promoting organic farming practice, farm income is increased than conventional farming.

This experiment was conducted to evaluate the effect of chitosan coating on physiological responses and nutritional qualities of tomato fruits at postharvest storage. There were four treatments of chitosan viz. T0 (control), T1 (0.10%), T2 (0.20%) and T3 (0.30%), and two storage conditions viz. in refrigerator (4°C) and room temperature (≈23-25°C). The matured light yellow tomato fruit samples were collected at 10, 20, 30 and 50 days after postharvest storage to assess physiological parameters viz. shelf life and weight loss as well as to determine lycopene and mineral constituents viz. Ca, Mg, P, S, Na and K. The mean weight loss of tomato fruits were 0.64, 1.28, 1.59 and 2.28% at 4°C, while it was 0.88, 1.84, 2.60 and 4.80% at room temperature at 10, 20, 30 and 50 days after postharvest storage, respectively. The shelf life of tomato fruits ranged between 58.3-100.0, 50.0-100.0, 33.3-75.0 and 16.7-66.8% at 4°C, while the ranges were 66.8-100.0, 50.0-100.0, 33.3-75.0 and 0.0-41.8% at room temperature at 10, 20, 30 and 50 days after postharvest storage, respectively. As regards to weight loss and shelf life, the study results inferred that chitosan coating with 0.2% solution is useful at postharvest storage of fruits. The study results revealed that storage temperatures (4°C and ≈23-25°C) had no effect on the total contents of different mineral element of tomato fruits but lycopene content reduced almost twice at refrigerated condition. On the other hand, the effect of chitosan coating on Ca, Mg, P, S, Na and K contents of tomato fruits at different days after postharvest storage were highly significant at both conditions. Finally, the study results concluded that 0.2% chitosan based coatings in tomato fruits proved to extend the shelf life by decreasing the decay incidence and weight loss, and refrigerated condition is better than that of room temperature.

Aim: In Africa, cassava provides a basic daily source of dietary energy and has gained popularity as one of the most important root crops in Nigeria especially in the Southern States. However, a thorough survey on cassava susceptibility to termite infestation in relation to time and management strategy has not received attention by farmers in Owerri (Southeastern Nigeria).

Study Design: Therefore, the need to carry out a field survey of cassava susceptibility to termite infestation as an influence by time, scale and management strategy in selected Owerri Agricultural zones.

Place and Duration of Study: The field survey was conducted in 2016 in four selected Agricultural zones of Owerri, Namely; Ezinnihite Mbaise (Zone 1), Owerri North (Zone 2), Mbaitoli (Zone 3) and Owerri West (Zone 4).

Methodology: A random selection of 30 cassava farmers from each of the study areas was made, totalling 120 respondents. Data were collected through structural questionnaire administration to the respondents on the four selected zones and were analyzed using Descriptive Statistics.

Results: Result shows that cassava stems were more susceptible to termite attack than tubers, especially during dry periods. Equally cassava devastation by termite occurred mostly at planting where newly planted cuttings suffered most. Termite infestation on cassava was more between January and May as well as between October and December. On the other hand, the use of chemical control either singly or in synergy with other non-chemical means to control termites appears to be very popular amongst respondents. Youths and mature adults were actively engaged in cassava farming, but the majority of them were unskilled by virtue of their low literacy levels.

Conclusion: Farmer education is recommended to enable the integration of pest/termite avoidance principle into termite control strategy.
