1 Department of Ecology and Environment, University of Batna 2, Batna, Algeria ABSTRACT. Shrubs and trees of the genus Ziziphus are a good example of naturally occurring multipurpose plant species with great potential in arid regions. This study was conducted to investigate the effect of cold stratification on seed germination and seedling growth of Ziziphus lotus (L.) Lam. Seeds were subjected to 0, 45, 90 and 120 days of cold stratification at 5°C. We also examined fruit, kernel and seed morphology. For each treatment period, four replicates of 50 seeds were incubated in plastic containers between two layers of moist sand at 15% and under greenhouse conditions for 15-day period. At the end of the experiment, the final germination percentage (FGP), shoot length and root length were assessed. The results clearly indicated that increasing duration of cold stratification improved seed germination. The most effective stratification period was 120 days where Z. lotus recorded 83% of FGP and 16.5 cm of total seedling length. Cold stratification treatments significantly increased shoot height, root length, as well as seedling total length. 120 days stratification treatment resulted in the highest shoot and root length (6.80 cm and 9.75 cm, respectively). An overview on the emergence of Z. lotus seedlings during a 15-day period was also illustrated.

This research was conducted to determine the effect of organic and inorganic fertilizers and bacteria inoculation on yield and its components on pea and faba bean in Dicle University Agricultural Faculty, Diyarbakir, Turkey, during 2018 and 2019 growing seasons. The experiment was laid out following a split-plot in completely randomized block design, with three replications. Fertilization treatments and cultivars were designed as main and sub factors, respectively. Data on plant height, plant biomass, pod weight, seed yield per plant, number of pods and number of seeds per plant, biological yield, seed yield and 100-seed weight were recorded at harvest. Number of nodules and nodule dry weight were record in flowering time. The effect of inorganic nitrogen, organic fertilizers and bacteria inoculation on grain yield, seed yield per plant, biological yield was significant at both pea and faba bean. Inorganic fertilizer (urea) was increased the grain yield (2147 kg/ha) and biological yield (4956 kg/ha) in faba bean, but close to control (2080 kg/ha and 4690 kg/ha). Organic-1, Organic-2 and bacteria treatments were decrease the grain yield and biological yield on pea and faba bean, and this decrease on pea was almost half over control.

1 Department of Agricultural Economics and Farm Management, University of Ilorin, Kwara State, Nigeria ABSTRACT. Farmers in Nigeria are unpredictable unlike other developing countries where a good agronomic practices are used for a sustainable increase in rice production as result, the demand for rice consumption far overweighs rice production. This study presented empirical findings on the sustainable agricultural practices and its constraints among the rice farming households in one selected state of Nigeria. The study utilized primary data collected in 2019 using a four stage random sampling techniques. A total sample of 150 rice farmers was collected with the use of descriptive statistics, Likert-type scale and multinomial logistic regression model for analysis. The result indicates that the recommended sustainable agricultural practices (SAP) least adopted were the use of High Yielding Variety seed and agrochemicals probably due to their high cost. The factors that influences the full usage of SAP in rice farming were farm size, level of education, farming experience, extension contact and access to credit. Also, farm size and access to credit also influenced the partial usage of SAP. The major constraints limiting the usage were high cost of fertilizers, high cost of improved seed and unavailability agrochemicals. The study recommends that extension agents should visit local farmers more often and carry out more demonstrations on the usage of SAP.

Chinese medicinal herbs and fruits have grown rapidly and significantly in recent years and have a positive influence on improving peoples attention to their health and organic life style. According to the advancement of sequencing technologies and reduced costs, the genome sequencing data of medicinal plants are accumulating rapidly. Our aim was to review plant genomes of three important medicinal plants in China. There is an ample genetic diversity of plants with medicinal importance around the globe and this pool of genetic variation serves as the base for selection, as well as for plant improvement. Plant genomes are characterized by large variations of genome size and ploidy level. Comparative genomics provides a method to unravel the relationship between genomes, by describing conserved chromosomes or chromosomal regions between related species. It is also clear that it is possible to use plant genome as a tool for improving breeding strategies. However, certain limitations represent a number of challenges for the generation and utilization of genomic resources in many important medicinal plant species. This review has focused on plant genomes of some important horticultural plants, which are famous in traditional Chinese medicine, namely ginger, ginseng and goji berry. However, more researches are needed to introduce the genome research of medicinal plants.

1 Experimental Station of Sidi Mehdi Touggourt, Algeria National Institute of Agronomic Research of Algeria ABSTRACT. Varietal recognition is a key step for good management of genetic diversity. Indeed, the morphological description of certain organs, such as the leaves, flowers, fruits and seeds, allow a more or less rapid and reliable identification of the varieties or cultivars. The culture of the pomegranate tree is very known in the valley of Oued Righ in the Algerian Southern, and it constitutes the main fruit species with a number of trees of 27.77 % of total number. The pomegranate tree is found in more than 84% of the farms of the region and its production is complementary of that of the dates. Unfortunately, no study has been realized on the characterization and the valorization of this species. To know and identify the varieties or the existing cultivars, we have undertaken a work of characterization of clones cultivated in the valley of Oued Righ. The plant material constituted by 13 clones of pomegranate tree stemming from various farms. The method of work consists in taking 20 fruits by tree for physico-chemical analyses in the laboratory. The results of analyses on sample of 13 clones described five cultivars, among which some present acceptable characters of fruit from a caliber point of view, contents in sugars and acidity. It shows that the naming of cultivars by the farmers based only on the acid taste of fruits "Hamad" or sweetened "Hlou" is not scientific and remain insufficient. Our results confirm the usefulness of morphological descriptors in the characterization of plant genetic resources. However, more clarification can be achieved by the undeniable contribution of molecular markers.
1阿尔及利亚国家农艺研究所Sidi Mehdi tougourt试验站，阿尔及利亚品种识别是优良遗传多样性管理的关键步骤。事实上，对某些器官，如叶、花、果实和种子的形态描述，可以或多或少地快速和可靠地识别品种或栽培品种。石榴树的栽培在阿尔及利亚南部的Oued right山谷非常有名，它构成了主要的水果物种，树木数量占总数的27.77%。该地区超过84%的农场都有石榴树，它的生产与枣子的生产是互补的。不幸的是，目前还没有对该物种的特性和价值的研究。为了了解和鉴定品种或现有品种，我们对在Oued right山谷栽培的无性系进行了鉴定工作。植物材料由来自不同农场的13株石榴树无性系组成。工作方法是每棵树取20个果实到实验室进行理化分析。对5个品种的13个无性系样品进行了分析，结果表明，其中部分品种的果实在口径、糖含量和酸度等方面均具有可接受的性状。由此可见，农民仅根据果实的酸味“哈马德”或甜味“哈娄”来命名品种是不科学的，存在不足。我们的结果证实了形态描述符在植物遗传资源表征中的有效性。然而，分子标记的不可否认的贡献可以实现更多的澄清。

Cherimoya (Annona cherimola Mill.) has an exceptional flavor and aroma, which makes it a fruit with great potential. However, little is known about its propagation by seeds. According to the scientific literature, the germination of cherimoya seeds is affected much more by external conditions than by internal conditions. Germination of cherimoya variety ‘Concha Lisa’ were tested for germination at constant temperatures of 25, 30, 40°C, and at room temperature, varying from 20-25°C, coupled with total darkness. Seeds were sown in Petri dishes (0.8% agar water), for 25 days of incubation. The kinetics of germination was determined according to five closely related parameters, viz. final germination percentage (FGP), mean germination time (MGT), coefficient of velocity of germination (CVG), time to 50% germination (T50) and seedling length (SL). The temperature of 30°C was found optimally suitable with 70.8% FGP, 17.5 days MGT and 3.91 cm SL, while the room temperature of 20-25°C slightly improved germination with only 25% FGP. Furthermore, significant decrease in FGP and SL was observed at 25°C and 40°C of temperature in comparison to 30°C. The analysis also revealed that cherimoya seed germination, day 10-15 after seed sowing is suitable for final counts. An overview on the emergence of cherimoya seedlings, during a 12-week period in pots is presented.

1 Agronomic and Horticulture Crops Research Department, Mazandaran Agricultural and Natural Resources Research and Education Center, AREEO, Sari, Iran 2 Soil and Water Research Department, Mazandaran Agricultural and Natural Resources Research and Education Center, AREEO, Sari, Iran ABSTRACT. Citrus rootstocks have prime effects on the size of tree and fruit, quality of fruit and micorhyza dependence, which make difference in their leaf mineral elements concentration in leaf of grafted cultivars on them. A pot factorial experiment with two factors including rootstocks (sour orange, Citrange, Rough Lemon, Citrumelo and Yozo) and grafted cultivars (Thomson Navel, Sanguine, Unshiu Tangerine) was carried out in farm conditions with three replications. The studied traits were concentrations of elements in leaves including nitrogen, phosphorus, potassium, sulfur, magnesium, iron, manganese, zinc and copper. The result of analysis of variance revealed significant mean squares of variety, rootstock and their interaction effects for the elements in leaves. Citrumelo rootstock had mainly effect on nutritional elements in leaves. Unshiu mandarin with Citrumelo rootstock had the most amount of nitrogen and sanguine variety with Citrange rootstock made the highest concentration of phosphorus and potassium in leaves of the grafted cultivar. Significant positive correlation of K with Fe and Zn indicating that all rootstocks with high mean value of K in leaf of grafted cultivar will have high amount of Fe and Zn. Significant positive correlation also detected between N and P of leaf of grafted cultivars in combination with different rootstocks; therefore, most of combinations with high mean value of N had also high mean value of P. Unshiu Tangerine had high variation for P, but Thomson Novel had lowest variation for this mineral element. Due to Significant positive correlation of S with Mg and Mn, most of rootstocks with high amount of S in leaf of grafted cultivar had high mean values of Mg and Mn in their leaf of grafted cultivars.

Effectiveness of integrated management approaches using blue sticky trap, pheromone trap, bio and synthetic insecticides were evaluated against major insects, like flower thrips and pod borers of mungbean at Regional Agricultural Research Station, Rahmatpur, Barishal and Pulses Research Centre, Ishurdi, Pabna, Bangladesh, respectively, during two consecutive years of 2018 and 2019. All of the management packages significantly reduced flower infestation, thrips population and pod borer infestation in mungbean. The highest percentage of reduction of flower infestation, thrips population and pod borer infestation was found in IPM package-3: installing blue sticky trap + two spraying of chlorfenapyr (Intrepid 10 EC) @ 1 ml/l + third spraying with (chlorantraniliprole + thiamethoxam), i.e. Virtako 40 WG) @ 0.15 g/l, followed by IPM package-1, IPM package-2 and recommended practice (spraying imidacloprid, i.e. Imitaf 20 SL @ 0.5 ml/l). The highest yield was also recorded from IPM package-3, which was statistically similar to IPM package-1, followed by IPM package-2 and recommended practice. Although the IPM package-3 provided the highest yield and return, followed by IPM package-1, but recommended practice (farmer’s practice) gave the highest benefit because of higher cost of IPM components brought down the profit margin of IPM packages. The components of IPM package-1, i.e. biopesticides, are ecologically safer than that of IPM package-3 (synthetic chemical insecticides). So, considering environment friendliness, the IPM package-1: installation of blue sticky trap and pheromone trap + two spraying of azadiractin (Biomeem plus 1EC) @ 1 ml/l + third spraying with spinosad (Success 2.5 EC) @ 1.2 ml/l would be the best package for controlling flower thrips and pod borers of mungbean with higher yield in the insects prone areas, without harming the ecosystem.

1 Siirt University, Faculty of Agriculture, Department of Field Crops, Siirt, Turkey ABSTRACT. This study was carried out to determine the effect of different boron application methods on cotton yield, plant growth and fiber technological properties. The study was conducted at Siirt University Faculty of Agriculture Department of Field Crops experimental area as randomized complete block design with four replications in 2018. Stoneville 468 cotton variety and boron liquid foliar fertilizer were used as material. Seven different boron applications were performed as (Control, 1000 cc ha at pre-flowering stage, 2000 cc ha at preflowering stage, 1000 cc ha at flowering stage, 2000 cc ha at flowering stage and 1000 cc ha at boll formation stage, 2000 cc ha at boll formation stage). The results of statistical analysis showed that there were significant differences between applications methods in terms of plant height and number of monopodial branches. But there were non-significant differences in terms of number of sympodial branches, number of first node of sympodial branch, number of nodes, height/node ratio, number of bolls, boll weight, seed cotton weight of per boll, number of seeds per boll, first picking percentage, 100 seeds weight, ginning percentage, seed cotton yield and fiber technological characteristics. In conclusion different application methods of boron increased plant height and number of monopodial branches of cotton when applied as 1000 and 2000 cc ha at preflowering stages.

This study seeks to assess consumers’ awareness, acceptability and willingness to pay for orange flesh sweet potato (OFSP) in Kwara State, Nigeria. Primary data, which was collected with the aid of a structured questionnaire, was used for the study. A three stage sampling procedure was used to select the respondents for the study. A total of 240 households were used for the study. The data collected were analyzed using descriptive statistics, contingent valuation method, logistic regression model and Likert-type scale. Result of analysis revealed 65% of the respondents were aware of the health benefits of OFSP, 89.3% of the consumers were most willing to pay above the bid amount for OFSP in the study area. Also, willingness of consumers to pay for OFSP is significantly affected by age of household head, household size, education of household head, bid amount and awareness of the health benefits of OFSP. The constraints to the consumption of orange flesh sweet potato include scarcity of OFSP, technicality of preparation, perishability and the cost of OFSP. The study therefore recommended that the benefits of OFSP over its indigenous counterpart should be more publicized through research institutes, extension agencies, health workers, NGOs and media for the populace to be more aware, which will enhance consumption in order to alleviate vitamin a micronutrients deficiency. Also, OFSP should be made available at reasonable prices, given that bid amount could dissuade consumers who are interested.
