Study of the Physicochemical Quality of Irrigation Water in the Rural Commune of Tighassaline (Beni Mellal-Khenifra, Morocco)

Morocco considers itself among the countries that have made great efforts in the field of watersavings. In agriculture, initiatives to switch from traditional irrigation to localized drip irrigation are widelyencouraged. This method of water supply allows farmers to save water and nutrients while ensuring betteryields in terms of quantity and quality. However, this production performance cannot be obtained without theobligatory passage to the analysis of all the factors of production. In this context, we evaluated during this studythe physicochemical quality of two wells supplying the irrigation network of an apple tree farm in the ruralcommune of Tighassaline, Beni Mellal-Khenifra, Morocco.The results showed that the pH values of the two wells are of the order of 7 and those recorded for the electricalconductivity are between 0.37 ms/cm and 0.55 ms/cm. These results demonstrate the quality of the irrigationwater, almost neutral and without any risk of salinity. These constants are supported by other measurements ofanions and cations contained in the water samples taken. In this regard, the concentration of chloride andsulphate is practically low in the two wells, while the concentration of bicarbonate is twice as high in well 2than in well 1. However, the most abundant cation compared to the others is sodium, with a concentration ofthe order of 1.10 meq/l and 0.9 meq/l for well 1 and well 2 respectively. The following study demonstrates theimportance of these analyzes in the appreciation of one of the main production factors and it proves that thewater from the two wells used to supply the irrigation network of the apple tree farm is very good quality.

Research Concerning the Fighting of Polystigma rubrum Fungi under the Climate Conditions of Șomcuta Mare Area

In this study, our goal was to survey the influence of the climate conditions, the behavior of the Centenar and Anna Spath varieties on the attack of the Polystigma rubrum fungi during the two experimental years (2013, 2014), in order to make recommendations for new plantations. Nine fungicides were tested, being determined their biologic efficiency, in order to identify the most efficient products. The experimental research was performed during 2013 and 2014, in a fruit tree farm belonging to SC Pomicola SA trade company in Somcuta Mare, Maramures county. The attack was calculated by determining the frequency, intensity and the attack degree. The agrometeorological data were recorded using the AgroExpert system, for surveying the biology of fungi. The linear-interrupted laying method was used, each made up of 5 plants/variant in three repetitions/product. The biologic efficiency of the tested products was lower at the Anna Spath variety than at the Centenar variety due to its sensitivity; the recommended products: Folicur Solo 250EW, Dithane M45 and Syllit 400 SC were the most efficient in the fungi combating.

Pengaruh Lingkungan Kerja Dan Stres Kerja Terhadap Kinerja Karyawan Bagian Produksi Pada PT. Bening Big Tree Farm Di Desa Sibang Badung

Sumber daya manusia adalah salah satu faktor penting dalam suatu perusahaan agar dapat mencapai tujuan perusahaan yang telah ditetapkan sebelumnya, baik tujuan jangka panjang maupun jangka pendek. Penelitian ini berjudul “Pengaruh Lingkungan Kerja dan Stres Kerja Terhadap Kinerja Karyawan Bagian Produksi pada PT. Bening Big Tree Farm di Desa Sibang Badung”.Rumusan masalah adalah bagaimanakah pengaruh lingkungan kerja dan stres kerja secara parsial dan simultan terhadap kinerja karyawan bagian produksi pada PT. Bening Big Tree Farm di Desa Sibang Badung. Penelitian ini dilakukan dengan tujuan “untuk mengetahui pengaruh lingkungan kerja dan stres kerja secara parsial dan simultan terhadap kinerja karyawan bagian produksi pada PT. Bening Big Tree Farm di Desa Sibang Badung, dengan mengambil sampel yang berjumlah 87orangkaryawan sebagai responden penelitian. Menggunakan metode pengumpulan data melalui observasi, wawancara, kuesioner dan studi dokumentasi dengan mempergunakan teknik analisis persamaan regresi linear berganda, analisis determinasi, uji t dan uji F dengan bantuan SPSS (Statistical Product and Service Solution) Version 21,0 for Windows. Berdasarkan analisis regresi linear berganda diperoleh Y= 6,161 + 0,367X1 + 0,331X2. Menjelaska bahwa ada pengaruh yang positif secara simultan antara lingkungan kerja dan stres kerja terhadap kinerja karyawan bagian produksi. Selanjutnya berdasarka analisis R2 sebesar 0,430 maka nilai kofesien Determinasi diperoleh D = ,43%. Hal ini berarti bahwa lingkungan kerja dan stres kerja secara simultanberkontribusi terhadap kinerja karyawan sebesar43% sedangkan sisanya 57% dipengaruhi oleh variabel lain yang tidak diteliti. Hasil uji signifikansi parsial (t-tes), diperoleh t1hitung = 5,085 > ttabel = 1,663 terletak pada daerah penolakan Ho dengan sig. 0,000 < 0,05 maka Ho Ditolak dan Ha diterima berarti lingkungan kerja berpengaruh positif dan signifikan terhadap kinerja karyawan. t2hitung = 4,828 > ttabel = 1,663 terletak pada daerah penolakan Ho dengan sig. 0,000 < 0,05 maka Ho ditolak dan Ha diterima berarti stres kerja berpengaruh positif dan signifikan terhadap kinerja karyawan. Hasil uji signifikansi simultan F(F-tes) diperoleh Fhitung =31,723 > Ftabel =3,11 terletak pada daerah penolakan Ho dengan sig. 0,000 < 0,05 maka Ho ditolak dan Ha diterima berarti Lingkungan kerja dan stres kerja secara simultan berpengaruh positif dan signifikan terhadap kinerja karyawan.

Titus Phase Ceramics from the Pine Tree Farm Site (41WD51) in the Lake Fork Creek Basin, Wood County, Texas

The Pine Tree Farm site, an ancestral Caddo site occupied during the Titus phase (ca. A.D. 1430- 1680), was recorded by Bob D. Skiles in June 1977, on the basis of investigations conducted there by Skiles and James E. Bruseth, then a graduate student at Southern Methodist University, as well as work done by Skiles in 1970. The site is on a flat upland landform (400 ft. amsl) ca. 300 m northeast of Myrtle Springs Branch, a tributary to Dry Creek in the Lake Fork Creek drainage in the East Texas Pineywoods. The Goldsmith site (41WD208) is ca. 0.4 km to the east on Dry Creek, and several kilometers below the dam at Lake Quitman. The Dry Creek drainage basin, as well as the Caney Creek arm of Lake Fork Reservoir, have clusters of Late Caddo period Titus phase sites. The main known feature at the site was a large trash midden or midden mound that was ca. 20 x 22 m in size and approximately 35 cm in thickness. The midden deposits contained many Caddo ceramic vessel sherds, animal bones, mussel shell, charcoal and other charred plant remains (hickory nut shells), and ash deposits. Most of the trash midden was excavated in 1970, but there were intact midden deposits along the western and southern part of the trash midden, and in June 1977, several small units were excavated by Skiles and Bruseth in those areas. The ancestral Caddo ceramics discussed herein come from Units 2-4 in the southern part of the trash midden, but are not all of the sherds that were recovered in that work.
