Differences between genotypes for all other parameters evaluated were however significant ( P < 0.05 ). Accession GH3609 recorded the most damaged grains (23.32%) and the highest (15.41%) grain weight loss, whereas OBATANPA recorded the lowest (9.81%) damaged grains whilst the lowest weight loss (8.26%) was observed in GH6182. The proportion of damaged grains correlated with weight loss (r = 0.96) and index of susceptibility (r = 0.82). All evaluated genotypes were susceptible to S. zeamais attack.

Length-weight relationship was used to determine growth pattern, condition factor and relative condition factor. Environmental variables such as water quality parameters affecting fish abundance were predicted with multiple regression analysis. G. niloticus was more abundant in Otu Lake than in Abiandu Lake. Male G. niloticus were significantly (P<0.05) more than female with female to male ratio of 1:1.8 and 1:1.7 in Otu and Abiandu lakes respectively. Gymnarchus niloticus showed negative allometric growth in the two lakes studied meaning that fish get slimmer as it increases in size. Condition factor of G. niloticus ranged from 0.24 to 4.09 and 0.59 to 3.73 and relative condition factor from 0.82 to 1.08 and from 0.92 to 1.12 in Otu and Abiandu Lakes respectively. High air temperature observed corresponded with high number of fish, while high amount of rainfall corresponded with low number of G. niloticus. Water quality parameters showed that depth, transparency, DO and BOD were significantly higher (P<0.05). The model used successfully predicted G. niloticus abundance.

The extraction of essential oils is carried out by hydrodistillation using a Clevenger-type system in order to determine and statistically compare the yield of each sample. The results showed that drying conditions significantly affect the EO yield of the three species.

In the same conditions, an optimal yield of 1.52% is obtained for Origanum compactum . For Thymus satureioides the maximum EO content is obtained after 3 to 5 days of drying in a temperature range of 15 to 25 °C. Out of these conditions, yields gradually decrease significantly to minimum yields at a 15-day drying period and a maximum temperature of 45 °C for all plants. The harvest period is also a crucial parameter in the improvement of the EO yield, the best EO levels were recorded during the period of March-August this period corresponds to the flowering stage of the three plants, which shows that the variation of the phenological stages is a key factor in the optimization of EO yields.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48005875","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}

Results showed that treatments of both experiments considerably reduced the seedling establishment of target weeds. Substantial inhibition of target weeds was noted in germination percentage (76.7%), energy (56%) and index (71.4%), respectively.

As land use change is associated with increasingly dynamic socio-economic activities, tracking land use change becomes more difficult with larger amounts of data to be processed. In this study, the modern technology of GIS and Remote Sensing was applied for the assessment of land use change and crop water requirements in Dong Hung district in the Red River Delta of Vietnam. Databases of land use for 2013 and 2018 comprising 2492 and 3473 land parcels with 32 and 36 land use types, respectively, were built from land use map and land use status report. The databases were then used to construct a database of land use change for the period of 2013-2018, which was finally used for land use change assessment. In addition, Landsat-8 OLI data was used to detect land use change for Summer-Autumn and Winter-Spring seasons of 2013 and 2018. Moreover, MODIS satellite data was also used to estimate the crop water requirements for the rice fields for the mentioned seasons in the district. The study revealed that there was a complicated conversion among land use types, but in general agricultural land decreased by 485.9 ha, while non-agricultural land increased by 493.23 ha mainly with the expansion of residential land and land for infrastructure development. Among agricultural land use types, however, only annual cropland, which mostly includes paddy land was narrowed down by nearly 770ha, meanwhile other agricultural land increased. Crop water requirement was found to change slightly during the study period.

Plant growth promoters (PGPs) have ability to enhance growth of plants and thus applied to improve production. The objective of this study was to enhance the sprouting and early growth of sugarcane budchips through exogenous application of plant growth promoters and CaCl2. It was hypothesized that application of growth regulators on budchips will improve the growth and yield of sugarcane. Keeping in view, a pot study was planned to elaborate priming effects of PGPs on sprouting and growth of sugarcane budchips, prepared by budchip scooping machine. The study was executed at Agronomic Research Area, College of Agriculture, University of Sargodha, Sargodha for two consecutive years during spring 2015 and 2016. Experiment was arranged under completely randomized design (CRD) having four treatments i.e. Control, NAA 1 mM, CaCl2 1 mM, NAA 1 mM + CaCl2 1 mM. It was observed that sugarcane budchips treated with NAA 1 mM + CaCl2 1 mM gave higher sprouting establishment percentage, produced taller and thicker plants, exhibited higher leaf area index and chlorophyll contents as compared to all other treatments during each year of study. Similarly, more root length, root fresh weight, root dry weight, shoot length, shoot fresh weight and shoot dry weight was achieved with application of treatment combination; NAA 1 mM + CaCl2 1 mM over all others including control during both years. Among all PGPs treatments, CaCl2 1 mM had minimum effect on all studied parameters of sugarcane but it was statistically at par with NAA 1 mM. The results of this study led to the conclusion that soaking of sugarcane budchips in NAA 1 mM + CaCl2 1 mM solution proved to be superior than all other PGPs treatments and control as it promotes early growth, better establishment of seedlings and improve its other characteristics.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44489584","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}
