Phosporous (triple superphosphate) was basally applied at the  rate of 0, 50, and 100 kilograms per hectare respec tively to  determine its effect on the growth and d eve lopment of these  Ellf.i!.:~fl:L~!.1L ~.. The rice variety RD-23 was transplanted one week  after incorporation of green manure. Nitrogen fertiliz er was  topdressed at the rate of 0, 20, 40, and 80 kilograms p e r hectar e  to determine the response of rice crop to added inorganic N  fertilizer.  The results show that all the species of green manure wer e  photosensitive and flowered 35 days after emergence. Significant  differences were observed on some agronomic characteristics. With  added P, the plants were taller, more nodule s were produced, and  highe r biomass was obtained than from the control. No s ignificant  differences was obtained ·in any paramet e r as the rate of  application of P was increased from 50 to 100 kilograms per  hectare. Biomass production was greatly affected by date of  planting of green manure. Green manure planted in March has a  higher biomass produced than those planted in November, and their  N accumulation in all the species was hig h.  With added inorgani c N, the grain yield, the weig ht of 1,000  grains, tiller number and straw yield were increased .This  relationship was found to be linear a s the rate of applied N is  increased. The grain yield, the straw yield, and the plant  heights were significantly higher with 80 kg of N applied . The N  and P uptake increased in both the rice grain and the straw with  increased levels of applied P and N . However, higher N and P  uptake was observe d in the grain than in the straw. 0aRicexResearch 0aFertilizers and manures1 aUpasena, Selawa H., eChairperson1 aGartner, Joseph A., eExamination Committee1 aSumitra Poovarodom, eExamination Committee2 aInternational Development Research Centre, Canada, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
