  • This study was investigated to find out the optimum planting densities fo Solanum njrum L. about growth characters. yield components and yield at 6 planting densities by direct sowing culture. The results obtained are summarized as follows: Studying the correlationship. the highly negative significances were found between planting densities and fresh eights weights per plant, on the other hand, the highly positive significances were found between planting densities and plant height. Plant height was long in dense planting, and short in spacious planting by direct sowing culture. Stem diameter was thick in spacious planting. and was thin in dense planting. Fresh wt. per plant was decreased in dense planting and was increased in spacious planting by direct sowing culture. Yield was highest in dense planting densities (10 x 20cm : 50plants/$m^2$) by direct sowing culture. Fertilizing ((N： P$_2$O$_{5}$ $K_2$O=6 : 6 : 6Kg/10a) was increased than without fertilizing because plant height and number of branch was good.d.

  • We studied the changes in growth characteristics of major cultivated rice in low- density transplanting. The culm and spikelet length did not change in low density transplanting conditions. As the distance between hills increased by 10 cm, the number of tillers per hill increased by an average of 4.4 and the number of grains per spikelet increased by 7.5. The cultivar that had more tillers and higher grain number in 80 hills per 3.3 m2 tended to have more tillers and grain in low-density transplanting conditions. However, the increase rate of tillers and grain in low-density transplanting was not significanty different from the tiller and grain number in 80 hills per 3.3 m2. The total branch number and branch length in spikelets increased in low-density transplanting conditions. The grain number per spikelet was also increased by the in low-density transplanting method.

  • The experiment was carried out to study the influence of planting densities and fertilizer application levels on some agronomic characters and yield of flower-head in Zingiber mioga ROSC. The results obtained are summarized as follows ; Plant hight was long in dense planting, and short in spacious planting. Stem diameter was thick in spacious planting, and was thin in dense planting. Flower-head weight per plant was decreased in dense planting and was increased in spacious planting. Yield was higher in dense planting densities (10$\times$20 : 50plants /m$^2$, 20$\times$20 : 25plant /m$^2$). Fertilizing (N : P$_2$O$_{5}$ : $K_2$O=15 : 15 : 15kg /10a) was increased than without fertilizing because plant height and number of stem was good.d.
