Abstract

The objective of the research was to study the interaction between soil moisture content and animal manure application on the growth of Mendong (Fimbristylis globulosa (Retz.) Kunt). The experiment was conducted in May until September 2016 in Kampung Lembur Sawah, Kamulyan Village, Manonjaya Subdistrict, Tasikmalaya Regency. A pot experiment was performed using a factorial design consisting of two factors and three replicates. The factors were soil moisture content (K) consisting of four levels i.e. k1 (100% field capacity (FC)), k2 (150% FC), k3 (200% FC), and k4 (250% FC); and animal manure application (P) consisting of p1 (cattle manure), p2 (broiler chicken manure), and p3 (sheep manure). The indicators of plant growth, i.e. plant height, number of tiller, fresh weight and dry weight of plant biomass, shoot/root ratio, percentage of  the >75cm-long stems, water consumption, and water use efficiency (WUE) were measured.  The results showed that  there was an interaction effect between the soil moisture content and animal manure application on the number of tiller at 45 days after planting (DAP), the percentage of the >75 cm-long stems, and the water consumption. The sheep manure application at any levels of soil moisture content resulted in better effect on the growth of Mendong, water use efficiency, and quality of stem (the percentage of the >75cm-long stems). The soil moisture content above the field capacity resulted in better effect on the growth of Mendong, indicating that Mendong is more suitable to grow on the land with the soil moisture content above the field capacity or saturated soil during the whole growing period. Keywords: Manure, Mendong, soil moisture content

Abstract

The objective of the research was to study the interaction between dose of humic acid and nitrogen fertilizer on the growth and yield of  rice. The experiment was conducted in May until September 2014 in Sukamanah village Cipedes sub-district Tasikmalaya city. A field experiment was done using as split plot design consisted of two factors. The dosage of humic acid were placed as main plot consisted of four levels i.e. 0 kg ha-1, 3 kg ha-1, 4 kg ha-1, and 5 kg ha-1; and the rate of N fertilizer, as subplot, consisted of 4 levels i.e.0 kg N ha-1, 45 kg  N ha-1, 67.5 kg  N ha-1, and 90 kg N ha-1. The variables observed were: (a) the levels of soil organic C before and after treatment, (b) the levels of crop N, and (c) the components of growth and yield. Nitrogen fertilizer efficiency was expressed in terms of  agronomic efficiency of nitrogen (AEN). The results showed that the growth and yield of rice given humic acid was higher than that without humi cacid. The increasing dose of humic acid i.e. 3 kg ha-1, 4 kg ha-1, and 5 kg ha-1 did not have significant effect. A higher response on growth and grain yield was shown at the dose of humic acid 3 kg ha-1. Nitrogen fertilizer gave significant effect on all growth variables and yield of rice. The higher the level of nitrogen fertilizer up to a certain level (i.e. 67.5 kg N ha-1 or equals to 150 kg  Urea ha-1), the higher would be the effect on all growth variables and yield. The increase in weight of grain ha-1 due to the increased level of nitrogen fertilizer compared to those without nitrogen fertilizer (control) were respectively 58.05% at 45 kgha-1 N, 150.54% at 67.5 kg  ha-1 N, and 168.13% at 90 kg ha-1 N. Humic acid increased the efficiency of N fertilizer. The most efficient dose of N fertilizer was 67 kg ha-1, equal to 150 kg ha-1 combined with humic acid 3 kg ha-1.
