In order for all crops in every farm to benefit equitably from such irrigation, therefore, watering of crops in the farms needs scheduling. In that view, therefore, an experiment was set out at KALRO-Mwea to investigate the effect of irrigation scheduling on growth parameters of two Nerica rice varieties. The experiment was laid out in a Randomized Complete Block Design in split-plot arrangement replicated thrice. It was justifiable to adopt this design for purposes of controlling variation in the experiment taken through taking account of spatial effects in the experimentation. Two rice varieties (Nerica 4 and Nerica 11) formed the main plots and four irrigation schedules (Daily, Every 4 days, Every 5 days and Weekly) formed the sub plots. Results indicated that the treatments significantly influenced plant height, fresh leaf weight, dry leaf weight, chlorophyll content, panicle length and panicle number of the two Nerica varieties at maturity. On the basis of research findings, it is recommended to the farmers in Mwea that the Nerica 4 on every 3 days and weekly irrigation schedules will be the best method to adopt.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75819089","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}

This study was aimed to assess the nutrient release potential and the weight loss dynamics during leaching of the above weeds to utilize them as organic liquid fertilizers. Thirty samples from each species of oven-dried leaves (5 g) were placed separately in 1 L of distilled water. Three samples of each species were randomly collected at 1, 3, 5, 7, 14, 28, 42, 56, 70 and 84 days and the massloss, electrical conductivity (EC), pH and nutrient contents of the leachates were determined. Four fertilizers (FP1; the selected weeds Tithonia diversifolia + Mikania scandens + Chromolaena odorata (W), FP2; (W) + topsoil, FP3; (W) + topsoil + coconut husk ash and FP4; (W) + topsoil + coconut husk ash + fish waste) were formulated and based on the nutrient contents the highest nutrient containing FP3 and FP4 were applied on Basella alba. Mass-loss was higher (p<0.05) for Mikania scandens (97%) followed by Tithonia diversifolia (95.8%) and the lowest for Panicum maximum (63.7%). EC and pH of leachates were increased over the time indicating the highest in Mikania scandens (2139±4.7 μS cm) and Lantana camara (7.86±0.06) respectively, and the lowest in Panicum maximum (877±7.6 μS cm, 7.40±0.02). Nutrient contents of the leachates of Tithonia diversifolia, Mikania scandens and Chromolaena odorata were higher than those of Panicum maximum. FP4 revealed the highest nutrients and growth performances of shoot height (25.0±0.9 cm), number of leaves (12.0±0.6), leaf area (70.7±1.6 cm), plant fresh weight (56.1±1.2 g) of Basella alba. The results are suggestive of the potential of utilizing Tithonia diversifolia, Mikania scandens and Chromolaena odorata for the formulation of organic fertilizers which would in turn be a low-cost strategy for effective control of these weeds.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79070248","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}

Elevation values deduced through Cartosat-1 and SRTM datasets were compared with actual Ground Control Points (GCP) recorded using Global Positioning System (GPS) for testing their accuracy. The forest cover map was created by Landsat 7 ETM+ data and subsequently superimposed on altitude map, generated using SRTM and Cartosat-1. Further, it was visually compared with the Survey of India topo-sheet (1:50000) for analyzing undulating topography and forest cover of Jharkhand. The comparative study based on different parameters for DEM dataset from Cartosat-1 and SRTM, reveals that SRTM data performed better than Cartosat-1 for the study of forest cover in different agro-climatic zones of Jharkhand.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80301881","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}

Planting density systems (1600, 800, 400, 266, 178 and 100 trees ha -1 ) also impacted soil properties. Water holding capacity varied between 16.6 to 26.1 % across systems while porosity ranged from 46.2–71.5 %. Likewise, bulk density and particle density had values of 1.2 to1.7 and 2.2 to 2.9 g cm -3 respectively. The mean soil organic carbon content was 0.38%, pH of 7.2, available N, P, K was 66.92, 13.91 and 77.85 mg kg -1 respectively. Soil and leaf micronutrients analyzed across six different density systems showed wide variations and indicated the need for optimum nutrient management.

The diversity of the microbial community in soil is closely related to the functions and structure of its surrounding ecosystem. The aim of this research work is principally on the identification of microbial population under different land use types in Akure, Nigeria. The land use types were oil palm, teak plantation, unclear forest, and cassava and sugar plantations. The soil samples were collected at depth of 0–15 cm, 15–30 cm and 30–75 cm on each land use area and were taken to the laboratory for microbial analysis. Microbial analysis was carried out using the dilution spread plates techniques of identification of microbial population. The bacteria isolates were identified by morphological and biochemical characterization using taxonomy scheme of Bergeys manual of determinative bacteriology. The fungal isolate were stained with lactophenol cotton blue and observed under the microscope for identification. The result showed that, there are 40 different species of bacteria and 10 fungal strains isolated from all the land use types. Some of the isolated bacterial species were from phylumactinobacter, bacteriodietes, firmicutes, proteobacter and that of fungi were representatives of phylum Ascomycota and Zycomycota. The data on bacteria and fungi were analyzed using ANOVA. The means of bacteria and fungi occurrence were separated using least significance difference at 5% level. It was found that the cassava land showed higher diversity of microbial population, this might be attributed to the effect of tillage on the land year by year which enhanced the free movement of air and encourages the availability of microbial population due to the presence of some microorganism in the tuber of cassava which had a great influence on soil organic matter contents via mineralization and decomposition.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89209632","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 of the analysis of variance showed significant differences among accessions for traits like days to flowering, days to maturity at p ≤0.01, and for number of primary branches and number of secondary branches at p ≤0.05. Seed yield per plant had significant correlations with number of capitula per plant, number of seeds per capitulum, number of primary and secondary branches.
