Abstract

The experiment was aimed to study the effect of Gigaspora rosea inoculant and nitrogen fertilizer on the growth of coffee Robusta seedling. Coffee seedling which were used came from seedling of hybrid variety from BP 42 and BP 358 crossing, age 1 month. Micorrhiza fungi inoculations which were used came from Gigaspora rosea species. The experiment was conducted at Sukamantri Experiment Station Bogor Agriculture University, from December 1996 to August 1997. The experiment was arranged in Randomized Block Design with three replications. The first factor was dosage of micorhiza inoculation, consisted of 0, 5, 10 and 15 g/seedling. TheĀ  second factor was dosage of nitrogen consisted of 0, 1.5, 3.0 and 4.5 g/seedling. Fungi inoculation treatment in the dosage 15 g/seedling showed the highest infection percentage but can not increase the growth of coffee seedling. Fungi inoculant in the dosage 5 g/seedling gave the best growth level, showed by variety height of seedling, trunk diameter; leaves total and leaves area, shoot and root biomass, compare to the other fungi inoculation dosages. The highest level of nitrogen in leaf was found in the dosage 4.5 g/seedling. Fungi inoculation in the dosage 5 g/seedling and nitrogen fertilizer in the dosage 3 g/seedling gave the highest level of leaves area and shoot biomass, compare to the other treatment combinations.

Abstract

Intercropping of maize, rice and cassava is commonly practiced by subsistent farmers on rainfed agriculture in Indonesia. In general, grain yield (if maize in intercropping is lower than in monoculture sole crop. This due to the fact that maize varieties planted in intercropping was bred and selected under elite, monoculture crop environment. Field experiments to evaluate grain yield relative stability (if the three selected maize breeding materials planted in association with rice and cassava were carried out In Pekalongan (Lampung), December 1994 - September 1995. All three breeding materials are relatively stable in respect to grain yield. Individual selection in MC-1 population will be practiced in association with rice and cassava.

Abstract

The objective of this research was to determine the effect of prestorage infiltration of CaCl2, infiltration of spermidine, plastic wrapping and waxing on the maintenance of banana shelflife and qualities at different storage temperatures. Prestorage infiltration of Cavendish banana (Musa Cavendishii) with CaCl2 inhibited fruit softening, the increase of sugar content in peel color index. Plastic wrapping could inhibit the increase of weight loss, pulp peel ratio, peel color index, and the decrease of appearance score. Treatment of fruit with spermidine infiltration store in cool temperature could maintain banana shelflife until 27.8 days or 8.1 days longer than control.

Abstract

The objective of this research was to study the development of the flower and fruit, to enable determining physiological maturity (PM) and the effect of fruit position and seed size on seed viability of Gmelina. Gmelina seed reaches physiological maturity at the age 32 days after anthesis to have maximum potential viability, vigor and seed dry weight. Fruit position has significant effect on germination potential. Seed size do not affect parameter observed, and so is the interaction between seed position and seed size. Fruit from the middle part of the tree´s stand has the highest germination potential and those from the top has the lowest. Seed having small (size 15-20 mm) has better viability compared with the big ones (> 20 mm) and seed from the fruit of the top and below which size 15-20 mm and > 20 mm.
