This study was designed to find out some cultural practices, i.e. the planting time and plant population, to minimize the yield losses of the second crop in ginger continuous cropping pattern. The pot experimental unit consist of planting time treatment (A) with 3 levels i.e. 1, 2, and 3 months after the harvesting of the first crop, and population treatment (B) with 3 levels i.e. 1, 3, and 5 plants/pot. The result shows that the growth and yield were not affected by the planting time treatment, but affected by the plant population treatment. By increasing the plant population from 1 plant/pot (equivalent to 33 300 plants/ha.) up to 3 plants/pot (equivalent to 99900 plants/ha.), the yield reduced about 27.56% in term of tuber fresh weight, but did not affect the tuber growth. Increasing the plant/ha. is not recommended since the production was appraised in term of tuber fresh weight.

The aim of this study was to see the salt tolerance of turf grass Puccinellia distans in term of ion accumulation and ionic interactions under salt stress condition. Plants were grown hidroponically in culture solution with addition of NaCI (0, 25, 50, 100 and 200 mM). High concentrations of NaCI brought about growth reduction; the decrease of shoot dry matters was in the range of 30-84% and 30- 70% for root dry matters. Although the yield of plants decreased so much in the presence of 200 mM NaCI, but plants were able to remain alive without showing any visible symptoms of injury. Much more Na was accumulated in the roots than in the shoots. Exposing plants to salinity result in the decrease of K, Ca, and Mg contents.

In this study, multi-compartment transport boxes were used to determine the mobility of ions in the execised roots. For measuring Na uptake, the concentrations of 1, 50 and 150 mM NaCI were used in the external medium, whilst Ca were 0 and 2. 0 mM. The uptake of K was measured from 1.0 mM KCI in the presence of Na (0.50 and 150 mM) and Ca (0.50 and 2.0 mM). In the present study, 22 Na and 86 Rb were used to label Na and K in the external medium, respectively. Addition of Ca inhibited Na uptake in the roots exposed to 1.0 mM and 50 mM NaCI, thought Ca was relatively less effective in 150 mM. High concentrations of NaCI brought about the reduction of K uptake. Calcium, however, did not show any importance in recovering the uptake of K from the adverse effect of Na when the roots were exposed 10 50 mM NaCI, thought stimulating effect of Ca was observed at 150 mM NaCI. The results revealed that the pattern of ionic interactions in Puccinellia distans differs much with that generally found in most of halophyte plants.

Pot experiments and laboratory analysis were conducted to determine the effect of N fertilization and level of water table treatments of wet soybean culture on nodule formation and seed yield of soybean. The pot experiment was conducted in Cibungbulang and laboratorium analysis, was at three different laboratories: Soil, Agronomy, and Pasture, Bogor Agricultural University, started on August, 1993 up to February, 1 994. Three factors to be evaluated, namely varieties (Lokon and Lompobatang), N fertilizer applications of 0, 140, and 280 mg pot -1 (equivalent to 0, 25, and 50 kg N ha -1), and the level of water tables of (control, -15 cm, -10 cm, and -5 cm below the soil surface). They were arranged in randomized complete design. The highest value of nodule dry weight of Lokon variety (0.707 p. was resulted from the plant grown under -15 cm water table without N fertilizer (0 mg N pot- ). Lompobatang highest value (1. 727g) on -10 cm water table and fertilized with 140 mg N pot -1. The increases of nodule dry weight by the treatment were 0.300 g (73.7%) for Lokon and 1. 134 g (194.5%) for Lompobatang, respectively compared to control. Both varieties showed highest value of seed weight per plant if grown under -15 cm water table and fertilized with 140 mg N pot -1. Compared to control media, respective increased seed weight per plant 1.94 g (12.9%) for Lokon and 5. 40 g (25.4%) for Lompobatang.

Zoysia matrella (L.) Merr. is a widely used ornamental grass, particularly in home and landscape gardens, because of its soft appearance and high quality. One of main problem is its low growth rate. Therefore, specific cultural techniques are required to accelerate its growth while maintaining its attractive appearance. This experiment was aimed to study the effect of sod size and planting distance of Zoysia mairella. on grass growth and development. The experiment was conducted at the IPB experimental station at Darmaga IV, Bogor, for 8 months and was completed in August 1990. The trials used a split plot design with 2 factors and 3 replications. Treatment consisted of 2 planting distances i.e. (20 x 20) cm and (25 x 25) cm, and 4 sod sizes, i.e. (2 x 2) cm, (5 x 5) cm, (8 x 8) cm, and (10 x 10) cm. The variables observed were percentage of coverage, rate of coverage, quality of leaf color quality of appearance, and uniformity of growth. The results indicated that population density did not significantly affect variables observed except for uniformity of growth. Hence, the larger the sod size, the higher its rate of coverage and the more uniform its appearance, but the lower its quality of appearance. Statistically, the sod size significantly affected the percentage of coverage, rate of coverage, quality of appearance, and uniformity of growth

The purpose of this experiment was to investigate the effect of various levels of seed maturity and conservation methods on seed vigor and seedling vigor of broad bean( Phaseolus vulgaris L.). The experiment was conducted at Darmaga IV Experimental Station, seed Science and Technology Laboratory - Leuwikopo IPB and BIOTROP, Tajur. Broad bean no. 1058 was used in this experiment. Seed vigor testing was carried out in the laboratory, using Completely Randomized Design, while Randomized Complete Block Design was applied to field experiment for testing seedling vigor. The treatment consisted of two factors as followed:(I) Levels of seed maturity: MI = 27 daf (days after flowering), M2 = 30 daf, M3 = 33 daf, M4 = 36 daf, and M5 = 39 daf (2) Conservation methods: K 1 = pods were spread out in the processing unit room for about 1 week, the seed moisture content was dropped to 40%; K2 = sun drying; K3 = artificial drying, using seed dryer 400C. Seed moisture content was dropped to 9 - 10% in K2 and K3 methods. Broad bean seeds harvested at 36 daf, the time when physiological maturity was reached, followed by either sun drying or artificial drying, showed a maximum seed vigor. However, a higher seedling vigor resulted from sun drying as compared to artificial drying. Before physiological maturity seed vigor and seedling vigor was still lower, while the vigor was reduced after physiological maturity.
