Two experiments were carried out at Parramoon Experimental Farm (EI- Dakahlia Govenorate) during winter seasons of 1998 - 1999 and 1999 - 2000. Seeds of dwarf pea Pisum sativum L. cv. "Master B.' were sown either on one or both sides of the ridges; 60 cm width at 10 cm apart. Plants were fertilized with three level of ammonium sulphate (20.5% N), calcium super phosphate (16% P20S) and potassium sulphate (48% ~O) l.e. (150, 200 and 75 Kg/fed.), (200, 250 and 100 Kg/fed.) and (250, 300 and 150 Kg/fed.) of each fertilizer, respectively.
Therefore. this experiment included 6 treatments which are the two plant densities arranged in main plots with three N, P and K treatments as sub plots.
Low plant density were significandy increased plant height, dry weight, dry matter % and No. of pods per plant and hepoctyl length at the first season only. Fresh yield per plant, per plot and per feddan, NPK content of leaves were significant increasing both season.
Plant density did not significantly affect theseparameters; No. of branches and leaves per plant, No. of seeds per pod, No. of pods per plant, seed yield per plant
and feddan, misocotyllength and dry seeds protein content %. .
Moreover. increasing NPK fertilizer levels clearly increased all vegatative characteristices of plant growth, fresh pod yield and seed weight per pod in both seasons. However, number and weight of pods per plant, per plot and per feddan were significantly affected by NPK fertilizer application levels only inthefirst season. Seed index and germination rate were also increased with increasing levels of NPK fertilizer only first season.
It could be concluted that low plant density combined with level of NPK fertilizer i.e. 250, 300 and 150 Kg of ammonium sulphate super phosphate and potassium sulphate, respectively improved dry seed yield and seed quality.
