Abstract

The study was conducted to generate component technologies for pole snap bean seed production planted on October, November and December 2011 at varying population densities of one, two and three plants per hill.

The field experiment was conducted at the Ifugao State University (IFSU), Lamut, Ifugao from September 2011 to March 2012. Experimental plots were laid out in a 3 x 3 x 2 factorial experiment arranged in a split-split-plot design with three replications.

Planting date and variety showed a highly significant influenced on the days to flowering and seed maturity. December planting matured the earliest (60.17 days) than October (71.94 days) and November (62.44 days) plantings. Burik variety significantly matured two (2) and half days earlier than variety Alno. No significant interaction effects were detected.

Number of seeds per pod, total seed yield per plot and computed seed yield per hectare were significantly affected by planting date. November planting gave the highest number of seeds per pod (7.50) and total seed yield of 1,304 g. Three (3) plants per hill produced the highest seed yield of 1,185 g per plot and 19.55 tons per hectare. Lowest of 939 g per plot and 16.1 tons per hectare (16.21 tons) was produced by one (1) plant per hill. Alno significantly produced higher number of seeds per pod while Burik significantly produced higher weight of 1000 seeds per plot. A highly significant interaction effect was observed by date of planting and variety on the weight of seed yield per plot.

December planting produced the highest percent good seeds (97.52 % ) per plot, lowest was 91.28 % planted in October. Burik seeds germinated rapidly (74.94 %) than Alno (60.76 %). A highly significant interaction effect by date of planting and variety was noted in percent germination and speed. A significant interaction effect by date of planting and population density was observed on percent good seeds.

Keywords: population density, planting date, component technology.
