The objective of this research is to determine the effects of micronutrients on date palm growth and which of these micronutrients are critical for improving growth combined with Paclobutrazol or without on in vitro of elongation stage. In vitro growth of two cultivars were determined by varying five treatments that included minor salts (EDTA-chelated iron, CuSo4,) alone or combined with Paclobutrazol. The effects of these five treatments on plantlet length, trunk thickness, rooting number and Chlorophyll A, B was investigated. The results obtained after three months showed that, increasing copper sulphate on MS elongation media combined with Paclobutrazol was more effective for increasing the trunk thickness as well as rooting number compared with normal MS level. While poor response was found when Fe was increased in the chelated form of Fe-EDTA on MS elongation media. For cultivars, Shishi gave the highest plantlets length as well as root number. The maximum content of chlorophylls A and B were observed when copper sulphate was increased on MS elongation media with cultivar Lulu. The survival rate after 3 months was related to the medium used during the elongation phase, the survival of plantlets reached to 98.66% with cultivar lulu at the acclimatization stage.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73319693","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 indicated that plants treated with 3g of urea produced the highest number of leaves in Albizia zygia seedlings only while 9g of composite fertilizer had the best growth performance in all the other growth variables. Albizia zygia and Blighia welwitschii, seedlings had the best results in soil treated with 6g of composite fertilizer, while Lophira alata and Pterocarpus soyauxii seedlings showed best growth in soils treated with 9g of composite fertilizers for all other parameters. Seedlings of species supplied with 9g of urea gave poorest growth performance. Low root/shoot ratios were obtained for all seedlings except for those of Albizia zygia treated with 6 and 9g of urea that had root/shoot ratios greater than 1.0. The effect of fertilizers on chlorophyll concentration was significantly different only for L. alata (P=0.05).

However, most studies considered wider or irregular soybean row spacing, compromising its capacity to recover after wheat harvest. This work studied the stress effects in relay soybean intercropping and suggests narrowing row spacing to improve soybean performance. The aims were (i) to compare growth and yield of two planting patterns and (ii) to separate the effect of water stress (WS) from the effects of other stress factors (OSF) induced by wheat on intercropping soybean. WS was evaluated comparing above-ground dry and grain yield of irrigated and non irrigated intercropping soybean, and OSF was evaluated comparing intercropping soybean with another treatment in which wheat straw (aerial biomass) was eliminated at soybean emergence, both irrigated treatments. In wheat, similar yields were obtained in treatments with an intercropping planting pattern with two rows for wheat and one for soybean (2:1) compared to three rows for wheat and one row for soybean (3:1). However, intercropping soybean at narrow row spacing (52 cm; 2:1) improve yielded 23% more than intercropping at 70 cm (3:1). During wheat-soybean coexistence, OSF prevailed on soybean and this effect persisted in later stages. After wheat harvest, OSF reduced the amount of light interception from R1 to R5 and depressed the crop growth rate (CGR) in 34%. However, in this period, WS also affected the radiation use efficiencies (RUE) which explained the greater fraction (66%) of the total stress induced by wheat in soybean CGR. Intercrop soybean yielded 182 g m-2 less compared to the unstressed sole crop control. Considering the wheat effects on soybean growth, 63% (116.5 g m-2) of the total yield lost were due to WS. Therefore, most of the performance of relay intercropping soybean was linked with water disponibility since early stages. However, at optimum water condition wheat competition by light and resources also affected soybean yield (OSF: 37%).","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"226 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78016833","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}

Wheat breeding has focused on maximizing grain yield and tolerance to abiotic and biotic stresses. Because of a lack of clearly defined selection criteria for breeding forage-type wheat, breeders usually rely on very laborious means to measure forage quantity and quality or they use imprecise visual estimates to quantify forage production. In a series of experiments conducted at Vernon, TX during 2003-2005, we determined correlations between selected morphological traits and the early-season forage DM yield in a range of wheat breeding lines and commercial cultivars evaluated by the Wheat Breeding Program of Texas A&M AgriLife Research. Early-season forage DM yield was highly correlated with tiller number, leaf length and width, and inversely correlated with specific leaf weight. Environmental variables modified the responses. A number of wheat breeding lines and cultivars had combined three out of the four evaluated morphological traits, including Abilene Ag Exp., Cutter, Fannin, HG-9, Duster, TAM 110, TX01M5009, TX01V6016, TX03M1179, TX04M410009, and Weather master 135. These cultivars/breeding lines have been recommended for dual-purpose use; thus, the morphological traits evaluated in our studies were desirable for selection of wheat with improved forage productivity.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77375733","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}

Vasinfectum (FOV). The incidence of the disease caused by FOV was evaluated every 10 days up to the 150th day after inoculation. The protection afforded to cotton following treatment by stimulators was assessed by determining the mortality rate of plants treated and inoculated FOV compared with untreated and inoculated controls. The degree of protection of cotton from Fusarium wilt was also determined through growth parameters, foliar pigment content (Chlorophylls and carotenoids) and an evaluation of the rate of lines. The results showed better protection of the cotton plants treated by the stimulators and inoculated by FOV through an increase in the number of healthy leaves, stem height, and stem diameter. This protection was also confirmed by an increase in photosynthetic activity of plants and a reinforcement of cell walls. The combination of these two molecules (MeJA + ETH) was better to induce this resistance against FOV compared to each of the two taken separately. The use of natural defence stimulators (SDN) is therefore an effective means of protecting cotton from FOV. Their application in the agricultural environment could contribute to the development of a well-reasoned, sustainable agriculture that is more respectful of the environment and human health.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84994699","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}

They consisted in questioning farmers about their identity, the cropping practices and the problems encountered in the practice of tomato cultivation. Then another step consisted in monitoring tomato farms for observing diseases and pests associated to tomato. The results of the study showed that tomato cultivation is concentrated in rural areas and is carried out by men with a very low level of education. The most cultivated varieties are petromech and cobra because of their resistance to certain pests. Several tomato diseases have been identified, however the most significant were seedling damping-off (Pythium sp, Fusarium sp, Rhizoctonia solani), plant wilting (Fusarium oxyporum and Ralstonia solanacerum), fruit anthracnose (Colletotrichum sp.), apical necrosis and root-knot nematode (Meloidogyne sp.). The main pests observed on tomato in the locality were Helicoverpa armigera (Lepidoptera), Bemisia tabaci (Homoptera), Dysdercus sp. (Hemiptera). This study provides a pathway from which further studies including mapping the different diseases could be conducted so as to better monitor and protect tomato cultivation. \u0000 ","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"63 11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77595322","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}
