SKRIPSI PENGARUH DOSIS SINAR GAMMA DAN DOSIS PUPUK NP TERHADAP HASIL BUNCIS (Phaseolus vulgaris L.)
ABSTRAC
An experimental concering the effect of gamma ray (Co-60) dosage and MF fertilizer dosage to the field of bean (Phaseolus vulgaris L.) was carried out in 25 Juli until 28 September 1993. This experimen carried out at Tanjungsari Village, Vindusari District, Magelang Regency, Central Java. The kind of soil is Latosol, soil pH 6.0 with an altitude of 975 The above sea level.
The purpose of this research is twe know the effent of gamma ray dosage in combination with NP fertiliser dosage to the yield of bean.
The experiment was arraused with Ranaonized comple tely Block Design (BOBD), srranged in Factorial, with two factors and three replications with analysis P table at and 14 and than Duncan Multiple Range Test at 5%.
Factor I : Dosage of gaana ray rediation (a) conciat of 4 levels, they are:
R0 : no treatment
R1 : 1 krad dosage
R2 : 2 krać dosage
R3 : 3 kred doesge
Factor II: NP fertilizer dosage (2) concist of 3 levels:
P0 : no treatment
P1 : 40 x 5/ha and 50 kg P/ha
P2 : 60 kg/ha and 120 kg P/ha
Dusage of gamma ray radiation gave a very significant effect to the height of plant, weight of pode pe por por p plant, the lenght of pods, the dry weight of straw and e signifi- onnt effect to sumber of pode, but no wignificant effect to
the age of flowering and the fresh weight of straw.
MP fertiliser dosage gave very significunt effect te the height of plent, number of peds per plant, weight of pode, lenght of pode, dry weight of straw and a significant effect to the fresh weight of straw, but no signifioint effect to the age of flewering
There was no interaction bedween Chana ray redintion dosage and NP fertiliser dosage for all observation para-
Dosage of gamma roy 2 krad (8) and 60 kg X/ha kg P/ha (P) fertiliser dosage gave a bester yield The highest yield of treatment combination (RP) 120 139.99 gram pez plunt or equivalent with 11.67 tonthe mod the lowest was obtained by treatment combination (RF) was 56.25 gram per plant or equivalent with 4.38 ton/hay
