To study the effect of drought stress, iron spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2013 on research Farm in Faizabad of Iran, as a split plot within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: level A) 50 ml evaporation from pan evaporation; level B) 100 ml evaporation from pan evaporation; level C) 150 ml evaporation from pan evaporation and level D) 200 ml evaporation from pan evaporation. Sub plots were considered with iron spray in three levels, included level A) 80 g/ha, level B) 130 g/ha and level C) 180 g/ha. The drought stress reduced seed yield, the 1000-kernels weight (TKW), the number of seeds per ear, the number of seeds per row in ear, the number of rows per ear about 39%, 6%, 31%, 14% and 27% less than control treatment, respectively. Using iron, as compared with control treatment, causes the increase of 1000-kernels weight from 295 to 311 g and the increase of seed yield from 5188 to 7078. The results obtained from the present research showed that iron spray has fairly improved the effects caused by drought stress.","PeriodicalId":9937,"journal":{"name":"Cercetari Agronomice in Moldova","volume":"28 1","pages":"34 - 43"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76422618","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}

In this study, recent survey data from Osun State, Nigeria, was used to examine the effect of food expenditure on farming households’ welfare in Nigeria. Logistic and OLS regression models were the analytical tools used. Food Insecurity Gap (FIG) and Squared Food Insecurity Gap (SFIG) were used to capture the severity of food insecurity among the households. The results showed that, all households sampled consume rice, beans, vegetable, fish and oil as basic food items, while only 32% of them consume potatoes. The regression results showed that the household size, per capita income, dependency ratio and age were the highly significant factors influencing food expenditure. However, the coping strategy that was mostly adopted by the farmers in the study area was to cut down on the numbers of food items consumed. Therefore, it was recommended that farm mechanization should be encouraged for optimal land use and productivity. In all, promoting agricultural policies with appropriate price incentives that focus on intensification, diversification and resource-stabilizing innovations will create more wealth for all categories of farming households and this in turn will ensure food security, especially in an era of economic deregulation.","PeriodicalId":9937,"journal":{"name":"Cercetari Agronomice in Moldova","volume":"1 1","pages":"79 - 90"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89398557","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}

So, Malaysia has become a target of rice exporting countries within and outside Asia. To solve this problem, a pre-sowing seed treatment was used as a physiological intervention to alleviate the impeding problems of achieving better growth and yield of Malaysian rice variety MR219. A glass house experiment, which involved the use of solutions of osmotic salts and plant hormones, was used for this investigation. Data on germination percentages, height, number of tillers and productive tillers, tiller efficiency and yield were taken. In both osmopriming and hormonal priming treatments, the highest number of tillers and productive tillers were from pre-germination. The tallest plants from osmopriming were from 150mM treatment, while 50 ppm GA3 had the tallest in hormonal priming. The highest tiller efficiency for osmopriming was from 150mM and and 200mM sodium chloride, while in hormonal priming it was 200 ppm salicylic acid. For yield per panicle in osmopriming, it was 50mM and 100mM magnesium chloride that had the highest, while in hormonal priming it was 200 ppm methyl jasmonate. Finally, the highest grain yield per hill was produced by 200 ppm methyl jasmonate in hormonal priming, while 50Mm magnesium chloride had the highest yield in osmotic priming. So, it is concluded that the use of 200 ppm methyl jasmonate and 50Mm magnesium chloride could be used as potential hormonal priming and osmopriming, respectively, for yield improvement of MR219 rice in Malaysia.","PeriodicalId":9937,"journal":{"name":"Cercetari Agronomice in Moldova","volume":"30 1","pages":"1 - 16"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87953675","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 objective of the current study was to evaluate the effect of compost on the growth performance and biomass production of A. nilotica. Completely randomized design (CRD) was used to analyze the variations among several growth morphological traits. Two parallel trials, pot trial (seedlings), field trial (saplings) were conducted simultaneously. Compost and litter mixture were applied in mentioned trials. Following treatments were used: T0 – control; T1 - 25% of compost and 75% of nursery soil; T2 - mixture of 50% nursery soil and 50% compost; T3 - mixture of 75% compost and 25% of nursery soil; T4 - where 100% compost was applied. Increase in plant growth was observed with the increases in the amount of compost mixture. In field trial maximum plant height, shoot length, root length, rootshoot ratio and biomass production was observed when 100% compost level was applied, while minimum was observed without any compost appli-cation. In pot trials, the maximum plant height, rootshoot ratio and biomass production was recorded when 75% compost level was applied. Overall, Acacia performed better with 100% of compost application in field trail and 75% of compost application in pot trial. The results of this study demonstrated the positive effects of compost on the growth of Acacia. The seedling development was improved considerably with different levels having greater percentage of organic fertilizer and it was concluded that compost improves soil fertility and it should be used as organic fertilizer in farming and forestry practices for improving crop growth and yield.","PeriodicalId":9937,"journal":{"name":"Cercetari Agronomice in Moldova","volume":"7 1","pages":"66 - 73"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74198252","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}

First, the watershed boundaries, canals and nodes maps was extracted from the GIS environment. Then, the ASSA model was simulated for a one hour design for a different return period; the outputs of the model were analyzed in the GIS software environment. The results showed that with increasing rainfall return period, 2806 nodes in underground and superficial networks of 114, 178 and 226 nodes were flooded and inundation during the return periods of 2, 5, 50, 10 years, respectively. Field surveys, existing elevation digital maps of the urban runoff network and simulations have shown that the main cause of inundation is the small size of the cross section of the duct, as well as the low slope in some parts of the network. Adaptation of the results of the simulation of rainfall-induced waterlogging in the study area with what happens every year confirms indicates the correctness of the simulations of the model. Moreover, simulation results of the model also showed that there is a good agreement between the simulated results and the measurement.","PeriodicalId":9937,"journal":{"name":"Cercetari Agronomice in Moldova","volume":"21 1","pages":"105 - 91"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83205007","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}
