Abstract

ABSTRACT Textile industry waste decreased environment quality, including agricultural soils. This condition caused the degradationof rice field irrigated with contaminated waste water. Rice fields in Rancaekek contaminated with heavy metals such as Pb. The presence of heavy metals in soil can be transported to plant tissues, especially when heavy metals are present in soluble form. The aim of the research was to study the effect of various UZAAKH fertilizer dosage on pH, total-N, and availability of Pb in paddy field contaminated with textile waste. The experiment was conducted in the greenhouse of Agriculture Faculty, Universitas Padjadjaran from December 2017 to March 2018. The experiment was arranged in Randomized Block Design (RBD), consisted of six treatments with five replicates: 150 ; 200 ; 250 ; 300 ; 350 kg ha-1 UZAAKH and 250 kg ha-1 Urea. Data were analyzed with analysis of variance (ANOVA) followed by Tukey’s test at 95% confidence level. The result showed significant effect towards pH and availability of Pb in soil, but negligible differences in Ntotal.Keywords : contaminant soils, heavy metal, textile waste, UZAAKH fertilizer

Abstract

Dairy farming waste in high volume especially in the form of flushing slurry can be unmanageable. Flushing slurry is lower in organic matter content compared to solid waste due to water saturation. In order to enhance the utilization, flushing slurry can be converted in liquid organic fertilizer with higher nutrient content. King grass (Pennisetum purphoides L.) plant is commonly used as livestock feed especially dairy cow in South Bandung area. The experiment was conducted between March to June 2018 in Pangalengan, South Bandung. The result shows no significant different between control specimen and liquid organic fertilizer teratments in plant hight, number of leaves, root weight, and root length. Although notable amount of plant leaves was demonstrated in D treatment compared to than that of control.

Abstract

Analysis of the farming system is an applied science which concerns on how to use resources efficiently and effectively in agricultural business in order to get maximum results. In this analysis, one of the important aspects on agricultural production is fertilizer. Liquid compound fertilizer is a fertilizer with several advantages such as simple application, complete and balanced required nutrients, labour and time efficient, and easy to procure and store. The purpose of this study was to determine the analysis of farming system on the application of liquid compound fertilizer on sweet corn. This experiment used a Randomized Block Design (RBD) consisted of 10 treatments (8 treatments of liquid fertilizer doses, one treatment of fertilizer dosage recommendations for NPK and one control (without fertilizer)). Each treatment was repeated three times, with the total of 30 experimental plots. The results of this experiment were the application of compound liquid fertilizer provides a high relative value of agronomic efficiency and profits on corn. The treatment of 1 ¼ NPK liquid fertilizer dose gave higher RAE, R/C and B/C values compared to the control. NPK liquid fertilizer has a significant effect on the variables of soil (pH, N, P and K content) and yield components (N, P and K uptake). In general, the use of NPK liquid fertilizer can significantly increase the yield, with the highest yield on 1 ¾ dose and the yield of corn plants (18,329 kg/ha).
