Case Study

Uptake and utilization of nitrogen from N,N-(Isobutylidene)diurea by rice plants

Rubio, J. L., and R. D. Hauck. Plant and soil 94 (1986): 109-123.

Two particle sizes of oxalamide and N,N-(Isobutylidene)diurea (IBDU) and tSN-labeLled urea were compared as nitrogen sources to rice at two rates under two watering regimes in transplant and direct seeding systems simulating rice cultivation. The pattern of fertilizer nitrogen uptake by rice plants was affected by the type of fertilizer, the particle sizes of oxalamide and IBDU, and the watering regime. Fertilizer nitrogen uptake generally paralleled soil nitrogen uptake throughout the growth period. Plant tops continued to accumulate some nitrogen during grain filling, but most of the nitrogen in the tops was transferred to the grains after heading. After heading, top dry weight, N content, and lSN content decreased substantially. Root weight and N content increased rapidly initially and then decreased at a decreasing rate until maturity.
Prior to the addition of nitrogen fertilizers such as N,N-(Isobutylidene)diurea, supplemental fertilizers were mixed with Decatur silty clay loam, Rhodic Paleudult, and 5 kg soil/pot: 1,000 mg phosphorus, 500 mg potassium, and 500 mg complete micronutrient mix. Nitrogen fertilizers such as N,N-(Isobutylidene)diurea were mixed into the top 5 cm of soil by removing 1,500 g of soil, mixing with the nitrogen source at two non-zero nitrogen rates, and returning it to the pot. Two watering regimens were evaluated in each N treatment, and each treatment was replicated 10 times. For the A/F treatment, soil water content was brought to 22% and incubated with amendments at ambient temperature for 21 days before flooding was applied and maintained at a height of approximately 5 cm above the soil surface. For the CF series, fertilized soils were left to air dry for 21 days before being flooded.

N,N-(Isobutylidene)diurea as a nitrogen source for potato

Elkashif, M. E., S. J. Locascio, and D. R. Hensel. (1983): 523-526.

N,N-(Isobutylidene)diurea (IBDU) and sulphur coated urea (SCU) alone or in combination with NH4N 03 were evaluated as nitrogen sources for potato on 2 sandy soils. Nitrogen fertilizers were applied either fully pre-sowing or in split applications at 134 or 201 kg N/ha. Tuber yield was highest with IBDU or SCU alone or in combination with NH4NO3, while tuber yield was lowest with 100% IBDU and SCU. Marketable yield was 25% and 27% higher with NH4NO3 than with 100% IBDU and SCU, respectively. Marketable and total yield increased with increasing nitrogen, and tuber specific gravity decreased slightly. Split application of nitrogen increased marketable yield and total yield at a location. Treatments with NH4NO3 alone or with NH4NO3 together with IBDU or SCU had higher leaf N, Mg, and Ca concentrations and lower K content compared to IBDU and SCU.
The nitrogen sources were: a) 100% NH4NO3; b) 100% N,N-(isobutylidene)diurea (IBDU); c) 100% SCU; d) 67% NH4NO3 + 33% IBDU; e) 67% NH4NO3 + 33% IBDU; and f) 67% NH4NO3 + 33% SCU. The nitrogen sources were applied as a single preplant application or 67% preplant application and 33% side application 4 weeks after emergence. Side application N for sources d to f was applied as NH4NO3 only. Micronutrients were applied at 112, 224, 56 and 56 kg/ha and all pre-planting applications were made. Pre-planting fertilizers were applied 10 cm below the soil surface, 10 cm on each side of the potato seed plots and side fertilizers were applied 25 cm from the plants.
