The experimental design used was randomized complete blocks (DBCA), consisting of five treatments and four replications. The treatments consisted of green manure covers: Canavalia ensiformis (T1), Mucuna pruriens (T2), Cajanus cajan (T3), Crotalaria juncea (T4), Phaseolus vulgaris (T5), a control, conventional system (T6) was also used, mainly the control was used for the determinations of green mass of weeds, height of the pearl millet and green mass of the pearl millet. The determinations evaluated were; coverage persistence (Mg Ha –1 ) at 0, 15, 30, 45 and 60 days, weed suppression (Mg Ha –1 ) at 30, 60 and 90 days, green mass of weeds (Mg Ha –1 ) at 30, 60 and 90 days, height of the Pennisetum glaucum (cm) at 60 and 90 days, green mass of the pearl millet (Mg Ha –1 ) at 60 and 90 days. The data obtained were subjected to analysis of variance (Test F 5%) and the means of the treatments with significance were compared by Tukey’s test at 5% probability of error. In the determination of the green mass of weeds, significance was obtained between the conventional system (Control) and the green manure covers, so it can be affirmed that the use of vegetable covers reduces the incidence of weeds, greatly benefiting the reduction of competition between the crop. of economic importance in question and weeds.","PeriodicalId":13209,"journal":{"name":"Idesia (Arica)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87531430","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}

Considering the diversity of Passiflora species and the need of studies that can elucidate the germination process of Passiflora seeds this study aimed was to evaluate methods to overcome seed dormancy in two Passiflora species ( P. morifolia and P. cincinnata ) by pre-germinative treatments as physical scarification, immersion in gibberellic acid (GA 3 ) and Promalin ® (GA 4+7 + N-(phenylmethyl) -aminopurine). To dormancy overcoming, the pre-germinative treatments were: scarification in sandpaper; immersion in water at 50 ºC for 5 minutes; imbibition in 400, 1000, 2000 and 3000 mg L –1 GA 3 for 5 hours; scarification in sandpaper + imbibition in 400, 1000, 2000 and 3000 mg L –1 GA 3 for 5 hours; and imbibition in 0.03, 0.45, 0.90 and 2% Promalin ® for 6 and 12 hours. The treatments were distributed in a completely randomized design, with four repetitions of 25 seeds. The data were submitted to variance analysis and the averages compared by Tukey test and Scott-Knott, respectively, at 5% of probability using the software SISVAR. Germinability, germination time, germination velocity, uncertainty and germination synchrony were evaluated. The results showed that 0.45, 0.90 and 2% Promalin ® for 6 and 12 hours were effective to overcome the seed dormancy in P. cincinnata . The treatment 1000 mg L-1 GA 3 achieved the highest result to overcome the dormancy in P. morifolia seeds.","PeriodicalId":13209,"journal":{"name":"Idesia (Arica)","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88710876","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}

Therefore, the effect of tillage depth (10, 20, and 30 cm) and share age (in hectares of operation in 20 two-hectare plots for each depth) on the MF399 tractor’s fuel consumption and drive wheel slippage was evaluated. The split-plot design based on a randomized complete block design was used for data analysis, and Duncan’s multiple range test conducted the mean comparison at α = 1%. The results show that tillage depth and share age significantly affected tractor fuel consumption and drive wheel slippage. Maximum (68.67 lit/ha) and minimum (44.73 lit/ha) average fuel consumption and maximum (21.32%) and minimum (11.84%) average drive wheel slippage percentages were measured in 30 and 10 cm tillage depths. Moreover, increasing tillage depth from 10 to 20 cm and from 10 to 30 cm respectively increased fuel consumption by 18.90 and 53.52% and increased slippage from 32.68% and 80.06%. Meanwhile, slippage exceeded 15% after respectively 30, 20, and 12 hectares of tillage in 10, 20, and 30 cm depths, and fuel consumption significantly increased after 14, 12, and 10 hectares relative to using new shares.","PeriodicalId":13209,"journal":{"name":"Idesia (Arica)","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73162985","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 climatic antecedents available for this area date back to the period 1942-1949, recorded by the German citizen Enrique Froehlich. Since 1995, the Arturo Prat University has carried out a systematization of the climatic information, obtained with an automated meteorological station, which has allowed us to currently have historical records of 25 years. The results of these analyzes indicate that the average temperature for this period is 18.6 ºC and the minimum 8.2 ºC. The absolute maximum temperatures are above 34 ºC throughout the year and the absolute minimums are below 5 ºC, dropping to –8.6 ºC, presenting a risk of frost that extends from April to November. The average relative humidity of the air is 35.6%. During the winter period, the accumulated chilling hours are 1,273.1 and 102.1 positive chilling units. The maximum radiation occurs in November with 26.6 MJ day-1. Average annual rainfall is 1.1 mm year –1 . The ecosystem of the Pampa del Tamarugal has presented an increase in the average temperature, being less than 2 ºC. The average relative humidity is low.
