1 Faculty of Agriculture and Natural Resources, University of Torbat Heydarieh, Torbat Heydarieh, Iran ABSTRACT. Salicylic acid (SA) is a well-known signaling molecule that plays an important role in resistance against pathogens, as well as adaptation to some abiotic stress factors, such as drought, heavy metal toxicity, chilling, heat and osmotic stress and can be a factor effective treatment for plants. The impact of SA on different plant processes under optimal environmental conditions is controversial. Also, SA as a plant growth regulator may have a positive effect on the regulation of physiological and biochemical processes of different plant species, such as seed germination, seed production, respiration, vegetative growth, flower formation and photosynthesis. In addition, SA as a regulator of cell growth, could contribute to maintaining cellular redox homeostasis by induction of the alternative respiratory pathway and the regulation of antioxidant enzymes activity and to regulating gene expression by inducing a RNA-dependent RNA polymerase. However, SA may act as a stressor, and may have a negative impact on different plant processes. Recent results indicate that the exogenous application of SA to plants have affect several on many physiological processes, such as control of ion absorption, stomatal closure and transport, reducing of stress and stimulation of growth and differentiation of plants, and also the controlled levels of SA in plants are important for improving performance and adaptation to environmental stimuli and emphasize its important role in plant health and protection. The present study investigated the effect of SA on different plant processes.

1 University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, Romania 2 Suceava Genebank, Romania ABSTRACT. Soil fertility, upon which plant growth and hence crop yield and quality depend, embraces its content of plant food (nutrients), its organic matter content, its structure, its ability to supply water and its depth. Excessive use of fertilizers with nitrogen products of ion nitric accumulation in the soil (temporary) and in plants, which disturbs the balance of photosynthesis, causes the appearance of necrosis and burns on leaves, severe intoxication and even death by asphyxiation phenomena and cyanosis at ruminants, children and old people. One of the ways of soil pollution through agricultural technology is overfertilization and, in particular, the administration of high doses of nitrogen fertilizers. Excess of nitrogen fertilizers, as well as their empirical application, have negative effects on harvest quality. The main aim of this study was to determine the effect of five nitrogen levels and different type of fertilizers on the agrochemical evolution of the chernozemic soil in the superficial horizon. Field experiments were conducted at the Agricultural Research and Development Station (ARDS) Suceava, Romania, in two growing seasons (2017 and 2018) with five nitrogen levels (80 kg/ha, 120 kg/ha, 160 kg/ha, 200 kg/ha and 240 kg/ha) and two type of nitrogen fertilizers (ammonium nitrate and urea).

The main objective of study is evaluated some new inbred rice and male sterile varieties under Distinct, Uniform and Stability (DUS) and Value of Cultivated and Used (VCU) Experiments. A number of seven rice varieties were used, Sakha 101, Sakha 102, Sakha 104, Giza 177, Giza 178, Giza182 and Egyptian Yasmine; moreover, GZ. 10154 and GZ 8564-Sp 70, as well as EGMS and CMS1 as promising lines to evaluating by DUS and VCU. The data were recorded on morphological and yield characters. The results could be concluded that: regarding to qualitative characteristics (PQ and QL), from 24 PQ and QL characters, the nine rice varieties recorded the same score for 19 characters; moreover, the rice varieties Egyptian jasmine was dissimilar in the score No. 24, 39, and 60, that referred to this variety belong to Indica type while the rice varieties Sakha 101and Giza 178 were similar only in score no.11, which belong to Japonica and Indica japonica types, that meaning these varieties were highly uniform and stability in qualitative characters than the other promising line GZ10154. Regarding to quantities characteristics (QN), from 27 QN characters, 9 rice varieties recorded the same score for 20 characters; moreover, the rice varieties Sakha 101, Sakha 102, Sakha 104, Giza 177, Giza 178, Giza 182, Egyptian yasmine and GZ 8564-Sp70 were similar in the score no. 1, 12, 23, 48, 49 and 50, while the promising line GZ 10154 was dissimilar in these scores during the two seasons, meaning that all these varieties were highly uniform and stability than the other promising, line GZ 10154. These results were conformed to VCU results, where the studied varieties recorded the highest grain yield/day. From these results could be concluded that all the varieties, except GZ 10154, accepted as a new rice release variety, but the promising line GZ 10154 required to more recurrent selection to increase their uniform, as well as CMS line was accepted could be evaluated under different conditions, but EGMS should be evaluated under heat stress conditions.

1 Plant Protection Dept., Faculty of Agriculture, Suez Canal University, Ismailia, Egypt 2 Agricultural Research Station, Barley Research Dept., Ismailia, Egypt ABSTRACT. Grains of field crops, such as wheat, maize, faba bean and white bean, are considered strategic food for humanity worldwide and Egypt. Unfortunately, percent losses of grains quantity may reach to 15-30%, as a result of stored product insect damage, and the losses increased dramatically in the last years, as an outcome of quickly productions of these pests. Experiments were conducted on infrared thermal imaging that demonstrate early detection of infestation by stored product insects in wheat, maize, broad bean, white bean and bean grains. The imaging is dependent on subtle significant differences in temperature between infested and healthy grains. Because the thermal imaging data are digital, computer programs can be used to analysis differences in temperature and mining figures explained for that. Results revealed that the use of thermal imaging offers an alternative method to detect an insect infestation. Data concluded that thermal imaging has the potential to identify whether the grains of crops that tested are infested or not, but is less effective in identifying which developmental stage is present. Moreover, it could apply this technique easily on a large scale in silos, storage, mills and granaries without negative impact on quality of stored grains.

1 Department of Agricultural Economics and Extension, Osun State University Osogbo Ejigbo Campus, Ejigbo, Osun State, Nigeria 2 Department of Agricultural Extension and Rural Development, Obafemi Awolowo University Ile-Ife, Nigeria ABSTRACT. The study examined the participation of rural women in exploitation of non-timber forest products (NTFPs), as a means of sustainable livelihood in Southwestern Nigeria. A number of 320 respondents were interviewed through pre-tested structured interview schedule in the four purposively selected forest reserves using a multistage sampling procedure. Data collected were presented using appropriate descriptive and inferential statistics. The mean age and mean year of experience in NTFPs exploitation were 40.9 ± 11.5 years and16.4±3.4 years, respectively. NTFPs participated by the respondents in the study area were palm fruits, vegetables, snails and fire wood among others. Actor categories identify in the NTFPs business chain were collectors, processors, traders among others. In addition, majority of the respondents show willingness to continue in NTFPs exploitation irrespective of alternative livelihood. The findings revealed that age (t=2.39), number of hours of collection per week (t=3.48), years of experience of NTFPs exploitation (t= -3.88) and external orientation (t=2.20) of respondents significantly contributed to their participation in NTFPs exploitation. The study concludes that participation in NTFPs exploitation by the respondents was moderate. It was recommended that more enlightenment programmes should be organized by relevant stakeholders for the rural women to create awareness on the income generation opportunities that abound in the NTFPs activities.

The evaluation and computation of yield stability of a genotype over environments is a critical component of a certain breeding program. The present study was intended to screen 11 advance chickpea (Cicer arietinum L.) genotypes and one check for genotype × environment interaction (G × E) at six locations with varying micro and macro climatic conditions for yield correlated phenotypic characters. A number of 11 advanced genotypes of chickpea and one check variety were assessed for their adaptability at six different locations of Bangladesh. The randomized complete block design (RCBD) with three replications was chosen to experiment. The means were used to compute Additive Main Effects and Multiplicative Interaction (AMMI) analysis of variance, followed by regression analysis to measure × E. The regression analysis showed significant genotype × environment interaction for all the phenotypic characters. The mean values of days to flowering, days to maturity, plant height, number of pods per plant and seed yield were highly significant for linear, as well as non-linear components of G × E. Chickpea yield was significantly (p< 0.01) affected by genotypes, the environments and G × E interaction, indicating that the varieties and the test environments were diverse. G × E was further partitioned by principal component axes. The first two principal components cumulatively explained 86.59% of the total variation, of which 53.34% and 33.25% were contributed by IPCA1 and IPCA2, respectively. The AMMI stability value discriminated genotypes G2 (BCX 09010-9), G3 (BCX 09010-2) and G8 (BCX 01008-4) the stable genotypes. The investigated genotypes exhibited varying adaptability in different environments. Genotypes G3 (BCX 09010-9) and G9 (BCX 01008-3) were stable genotypes with high yield over a wide range of environments are promising candidate chickpea varieties.

1 Laboratory of Plant Systematics, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, Bangladesh 2 Department of Agriculture Extension, Sirajganj, Bangladesh ABSTRACT. Three separate field experiments were conducted to exploit biomass yield potential of dhaincha (Sesbania species) by different cultural practices. A total of six accessions from three Sesbania species, viz. S. bispinosa (#05, 71, 77 and 109), S. cannabina (#28) and S. sesban (#81), were used as experimental materials. Experimental treatments were population densities, viz. 180, 240 and 300 plants m; sowing dates, viz. 30 April, 15 May, 30 May and 15 June, and fertilizer doses, viz. 0 (without N/control), 10, 20 and 30 kg N ha. All the experiments were designed following randomized complete block design with three replications. Experiments on population density and sowing dates were conducted in control condition (without any fertilizer application). The N-fertilizer was applied as top dress at 30 days after sowing (DAS) and crops were harvested at 60 DAS. The maximum biomass (10.07 t ha) was obtained from 240 plants m. At 30 April sowing, plants produced the tallest height (199.69 cm), widest base diameter (1.02 cm), highest fresh weight (62.07 t ha) and biomass yield (14.73 t ha). There were no significant differences in biomass yield and yield contributing descriptors between 20 and 30 kg N ha. Among the species, S. bispinosa was the best performer in terms of biomass yield and yield contributing descriptors. It may be concluded that S. bispinosa (accession #71) could be cultivated with the population density 240 plants m, at 30 April, without any fertilizer application. In case of later sowing/cultivation, the 20 kg N ha could be applied for the maximization of biomass yield.

In case of later sowing/cultivation, the 20 kg N ha could be applied for the maximization of biomass yield.","PeriodicalId":9937,"journal":{"name":"Cercetari Agronomice in Moldova","volume":"118 1","pages":"160-176"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81673282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability to reuse treated wastewater (TWW) would be of significant benefit to agriculture whilst at the same time providing a valuable water resource. This study concerned the effects of three various levels of treated wastewater (0%, 50% and 100% TWW) on seed germination and plant development of three different varieties of tomato (Lycopersicon esculentum) (viz. Toufan, Heinz and Bouzina). Irrigation with TWW persisted 15 days for the germination stage and 120 days for the growth and development stage. A control plot irrigated with a pure water (groundwater) was also set up in order to compare the seeds and the plants response to different concentrations of irrigation water. The final germination was expressed as a percentage of the total number of seeds in each treatment. This study has demonstrated that treated wastewater improves the germination in Heinz variety and had no effect on both Toufan and Bouzina varieties whether it is pure or diluted by half. For the growth stage, the statistical analysis showed that the Toufan variety has tolerated successfully the TWW irrigation with its high and moderate concentrations, and this by analysing all the morpho-physiological parameters studied in this work (leaves numbers, stem and root length and dry biomass, relative water content and rate water loss).
