Estimation of gross primary production of irrigated maize using Landsat-8 imagery and Eddy Covariance data
No full textAbstractA study was conducted to understand the potential of Landsat-8 in the estimation of gross primary production (GPP) and to quantify the productivity of maize crop cultivated under hyper-arid conditions of Saudi Arabia. The GPP of maize crop was estimated by using the Vegetation Photosynthesis Model (VPM) utilizing remote sensing data from Landsat-8 reflectance (GPPVPM) as well as the meteorological data provided by Eddy Covariance (EC) system (GPPEC), for the period from August to November 2015. Results revealed that the cumulative GPPEC for the entire growth period of maize crop was 1871gCm−2. However, the cumulative GPP determined as a function of the enhanced vegetation index – EVI (GPPEVI) was 1979gCm−2, and that determined as a function of the normalized difference vegetation index – NDVI (GPPNDVI) was 1754gCm−2. These results indicated that the GPPEVI was significantly higher than the GPPEC (R2=0.96, P=0.0241 and RMSE=12.6%). While, the GPPNDVI was significantly lower than the GPPEC (R2=0.93, P=0.0384 and RMSE=19.7%). However, the recorded relative error between the GPPEC and both the GPPEVI and the GPPNDVI was −6.22% and 5.76%, respectively. These results demonstrated the potential of the landsat-8 driven VPM model for the estimation of GPP, which is relevant to the productivity and carbon fluxes

Characterization of spatial variability of soil physicochemical properties and its impact on Rhodes grass productivity
No full textAbstractCharacterization of soil properties is a key step in understanding the source of spatial variability in the productivity across agricultural fields. A study on a 16ha field located in the eastern region of Saudi Arabia was undertaken to investigate the spatial variability of selected soil properties, such as soil compaction ‘SC’, electrical conductivity ‘EC’, pH (acidity or alkalinity of soil) and soil texture and its impact on the productivity of Rhodes grass (Chloris gayana L.). The productivity of Rhodes grass was investigated using the Cumulative Normalized Difference Vegetation Index (CNDVI), which was determined from Landsat-8 (OLI) images. The statistical analysis showed high spatial variability across the experimental field based on SC, clay and silt; indicated by values of the coefficient of variation (CV) of 22.08%, 21.89% and 21.02%, respectively. However, low to very low variability was observed for soil EC, sand and pH; with CV values of 13.94%, 7.20% and 0.53%, respectively. Results of the CNDVI of two successive harvests showed a relatively similar trend of Rhodes grass productivity across the experimental area (r=0.74, p=0.0001). Soil physicochemical layers of a considerable spatial variability (SC, clay, silt and EC) were utilized to delineate the experimental field into three management zones (MZ-1, MZ-2 and MZ-3); which covered 30.23%, 33.85% and 35.92% of the total area, respectively. The results of CNDVI indicated that the MZ-1 was the most productive zone, as its major areas of 50.28% and 45.09% were occupied by the highest CNDVI classes of 0.97–1.08 and 4.26–4.72, for the first and second harvests, respectively
Impact of soil firmness and tillage depth on irrigated maize silage performance
No full textAbstract. A field experiment was conducted to investigate the response of maize silage ( L.) to tillage depth under different soil firmness levels. The study was carried out on a 16 ha center-pivot irrigated field in a commercial farm located in the eastern region of Saudi Arabia. A soil firmness map was generated and used as a management map. This map was divided into three soil firmness zones based on soil cone index (low: 617 to 1270 kPa for a 0 to 15 cm depth in undisturbed soil, medium: 1271 to 1652 kPa and high: 1653 to 2306 kPa). Three tillage depth treatments (10, 20, and 25 cm) were imposed on each of the three soil firmness zones, using a tandem disc harrow. Maize growth parameters [plant population, plant height, and Normalized Difference Vegetation Index (NDVI)] and maize silage yield were used to evaluate the response of the maize crop to tillage depth. The results revealed that soil firmness and tillage depth at both early (25 days after sowing) and late (60 days after sowing) growth stages did not introduce significant effects on maize plant population. However, the plant height measured at 60 days after sowing showed a significant response to soil firmness. The lowest mean value of plant height (114.4 cm) was recorded at the high soil firmness level, while the greatest mean value (136.3 cm) was recorded under low soil firmness level. Also, significant differences in maize silage yield were recorded under different soil firmness levels and tillage depths. For maize silage production, a tillage depth of 10 cm was observed to be optimum for areas of low and medium soil firmness. For areas of high soil firmness, the optimum tillage depth was 20 cm.

Examining Al-Khazin's Influence on Tafsir Writing in Indonesia (A Study of 17th and 20th Century Tafsir)
No full textThis research is based on the opinion of Abdur Rauf Al-Fansuri and Bisri Musthafa who mentioned that the writing of the tafsir book takes reference sources from the Al-Khazin interpretation, even though these two tafsirs were born in different centuries. The purpose of this research is to see how much influence Al-Khazin has in writing tafsir, especially the 7th century and 20th century tafsir and in what way Al-Khazin influences his interpretation. This research uses the literature study method by analyzing several sources both primary and secondary. The result of this research is that Al-Khazin proved to have a considerable influence on the writing of Al-Mustafid Tarjuman's interpretation and Al-Ibriz’s interpretation. this can be seen, taking interpretations of several aspects. The first, aspects of hadiths or narrations, although both interpretations tend to rarely include sanads in their entirety. Second, taking the asbab nuzul verse. Third, the aspect of the story of israiliyyat or the story of the previous prophet. In addition, there are similarities and differences in including Al-Khazin's interpretation in both interpretations such as both interpretations both use signs to strengthen their interpretation including the interpretation taken from Al-Khazin, the difference is that Al-Mustafid Tarjuman's interpretation provides a clear explanation if the interpretation takes from Al-Khazin’s interpretation is different from Al-Ibriz’s interpretation which does not clearly express Al-Khazin's interpretation in his interpretation Penelitian ini dilatar belakangi oleh pendapat Abdur Rauf Al-Fansuri dan Bisri Musthafa yang menyebutkan penulisan kitab tafsirnya mengambil sumber referensi dari tafsir Al-Khazin, padahal kedua tafsir ini lahir dalam abad yang berbeda. Tujuan penelitian ini untuk melihat seberapa besar pengaruh Al-Khazin dalam geliat penulisan tafsir khususnya tafsir Abad 7 dan abad 20 dan dalam hal apa Al-Khazin mempengaruhi penafsirannya. Penelitian ini menggunakan metode studi kepustakaan dengan menganalisis beberapa sumber baik primer maupun sekunder. Hasil dari penelitian ini adalah Al-Khazin terbukti memberikan pengaruh yang cukup besar terhadap penulisan Tafsir Tarjuman Al-Mustafid dan Tafsir Al-Ibriz. hal ini terlihat, pengambilan penafsiran terhadap beberapa aspek diantaranya yaitu pertama, aspek hadits atau riwayat walaupun kedua tafsir cenderung jarang memasukkan sanad secara utuh. kedua, pengambilan asbab nuzul ayat. ketiga, aspek kisah Israiliyyat ataupun kisah nabi terdahulu. selain itu, terdapat persamaan dan perbedaan dalam mencantumkan penafsiran Al-Khazin dalam kedua tafsirnya seperti kedua tafsir sama-sama menggunakan tanda untuk menguatkan penafsirannya termasuk penafsiran yang diambil dari Al-Khazin, perbedaannya yaitu Tafsir Tarjuman Al-Mustafid relatif memberikan penjelasan jelas jika penafsirannya mengambil dari Tafsir Al-Khazin berbeda dengan Tafsir Al-Ibriz yang tidak secara jelas mengungkapkan penafsiran Al-Khazin dalam tafsirnya
