Value of Land Use for the Transportation of Nutrients in the Bulan Sub-Watershed

Ummu Kultsum, Supratman, Anwar Umar

Abstract: Nitrogen (N) and phosphorus (P) are nutrients or chemical content needed by living things, one of which is plants.This content can be transported by run off to rivers or water bodies so that it has an impact on soil fertility and high content in rivers causing eutrophication (water pollution).This can be accelerated by human activitie, namely land use patterns.Therefore, efforts in controlling the impact through value or cost approach in the form of water treatment in minimizing the content of N and P in rivers and fertilization costs on land use patterns in restoring soil fertility. This study aims to (1) analyze the content of N and P rivers in each land use outlet; (2) know how much value or water treatment in minimizing the content of N and P in the river and the cost of fertilization on the pattern of land use in restoring soil fertility. This research is a descriptive type of research using a survey method that is to take samples and water observations by purposive sampling. Water sampling was conducted at four different land use outlets in Bulan Sub-Watershed of the which is the upstream Jeneberang Watershed that serves as a catchment area for water and water suppliers in Bili-Bili Reservoir as well as water raw materials of Tirta Jeneberang Municipal Waterworks. The results showed that the use of agricultural forest land chemical content in the form of N and P is greater than pine forest. In addition, pine forest outlets can save water treatment costs in minimizing N and P by IDR 2.747.946.765 while the cost of fertilization on agricultural land is 5-6 times greater tha pine forests.

Influence of Different Sources of Organic and Inorganic Fertilizers on Tomato (Solanum lycopersicum mill.) Growth, Quality and Soil Properties

Arifa Nazir, Javeed Iqbal Ahmad Bhat, Zubair Ahmad Dar, Abdel Rahman M. Al Tawaha

Abstract: A pot culture experiment was conducted at the Experimental Farm located in Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar campus during kharif season 2018. This study was carriied out in Completely Randomized Design with three replications comprised of nine treatment combinations of sewage sludge (SS), aquatic weed compost (AWC) and inorganic fertilizers. However, in this study, it was initiate that the conjoint use of sewage sludge with chemical fertilizer (T5) recorded maximum build-up of soil macro nutrients (NPK), plant growth and quality parameters. However, the micro-nutrient concentrations in soil exposed to sewage sludge and aquatic weed compost were significantly higher than those in the untreated plots, with highest concentration found in sole application of sewage sludge (T3). All the micro nutrients studied were within the acceptable limits and did not overcome the maximum levels of phytotoxic. This experiment concludes that the application of sewage sludge and aquatic weed compost did not have any adverse impact on fruit quality and it was suggsetted to for the improvement of plant growth and soil fertility.

Principle Component Analysis among Exotic and Egyptian Rice Genotypes

Maysoun M. Saleh, Abdelmoaty B. Elabd, Abdel Rahman Mohammad Al Tawaha

Abstract: Twenty-five rice genotypes with two Egyptian rice varieties: Giza 178 and Sakha 105 were all cultivated in a Randomized Complete Block Design (RCBD) with two replications under saline soil at at El_Sirw Agriculture Research Station northern part of Delta, Egypt during the growing season 2012. This study aimed to evaluate the potential divergence among tested genotypes and to define the role of agronomic traits in the total variation by using principle component analysis. Results showed that high variability was noticed between the testes genotypes, and indicated that only four principle components PC1, PC2, PC3 and PC4 were significant as they had an Eigenvalue greater than 1.0 (2.3967, 2.1444, 1.7225, 1.0618) respectively, explained together 73.3% of existed variation between genotypes. The first principle component PC1 explained the highest variation 24%, followed by other components PC2, PC3 and PC4 which explained (21.4, 17.2, 10.6) % of the total variation. Results also revealed that days to flowering and number of filled grains per panicle were associated with PC1, whereas three traits (tillers per plant, panicles number per plant and thousand grain weight) were gathered in PC2, and the PC3 consisted of (panicle length, panicle fertility and grain yield per plant), while the last component PC4 contained both traits flag leaf area and plant height. It was concluded that the divergence between rice genotypes in our study provide a wide genetic base for breeders to improve rice.
