An original soil pH of 5.3 was changed to 5.5, 6.5 and 7.5 by applying calcium carbonate. The resulting various in growth, yield and leaf sap pH were observed in corn (bantam), soybean (hill) and buckwheat (native). Sample were taken at 3 week intervals during the growing stage 5 times a day every 3 hours starting at 6 a.m. At the same intervals another 8 species were investigated a t 9 a.m., noon and 3 p.m. irrespective of growth condition. Average plant leaf sap pH occured at noon, plant sap acidity seemed to be changed by some factors including plant species, sampling time of the day, growing stage and soil acidity. The average pH of leaf sap of corn was 5.52, of baryard grass 5.85, of buckwheat 4.83, soybean 6.64, garden pea 5.99, sweet potato 5.98, oriental cocklebur 5.99, speedwell 5.98, siegesbekia 7.13, and common nightshade 6.79. Soil acidity influenced the pH of leaf sap very slightly. Also differences leaf sap pH seemed to affect the length of time taken for germination, plant length, heading date, ripening period, weight of 100 grain and yields in the same plant.

. Ten varieties (caassified by grain colors) of local corn were collected from Cheju-do and mainland. The corn grains have a wide range of colors, white,yellow,yellowish, gray,violet,brown,dark brown,black brown, red and black. Open pollinated results(changes of grain colors) were as follows: When yellow corn(seed parent) is pollinated by white corn(pollen parent), the grains are yellow but are lighter in color and often capped with white. When white corn is pollinated by yellow corn, the grains are yellow. When white corn is pollinated by black corn, the grains are black. When yellow corn is pollinated by black corn, the grains are black. When yellow corn is pollinated by violet corn, the grains are black.

1. This experiment in order to decide of adaptable sowing time and choose of wintering crops, using garden pea. 2. The garden pea is adapted to a cool climate, high temperatures are particularly disastrous when the pods are setting, on the other hand, the plants are quite frost resistant. 3. Where nematode infestation is a problem, the peas should be planted late in the fall and turned under early in the spring to avoid periods of nematode acitivity. 4. Garden pea is a good wintering crop in cheju but there are many problems, for example, fusarium wilt, root rots, nematode, and humid. 5. The adaptable sowing time of garden pea is from December to January in Cheju.

The work has taken place in Suweon, Using plants were smartweed (polygonum Conspicum Nakai), dayflower (commellina communis L.), stichwort (Alsine Grimn var. undulata ohwi), larger crabgrass (Digitaria Adscendis Henr.), Common purslane (portulaca oleracea L.), amaranth (Amaranthus Asendens Loisel.), umbrella plant (Cyerus Differmis L.), water foxtail(Alopeculus Aequalis sobel var. amurensis ohwi.), green foxtail (setaria viridisp. Beauv.), siegesbeckia (siegesbekia glabresens Makino), oriental cocklebur (Xnthium L.), goose foot (chenopodium Album L.), wild oat (Abena fatua L.), shepherd's purse (Capsella Bursa-pastoris Medicus), fielder corn (Ixeris stolonifera Maxim), bindweed (Calystegia japonica choisy), araceao (pinellia ternata Breitenbach), Curly dock (Rumax crispus L.), flat sedge (Cyperus micr-oiria steud.), bog pondweed (potamoton distincts A. Bennet), dandelion (Taraxacum Dahl.) and squill (scilla scilloides Druce.), Result were as follow : (1) Wintering weedy plants were emergencing from deep place than emergence in Summer. (2) A knowledge of the manner of weedy plants and of the agencies responsible for their dispersal forma a basis for prevention of introduction and spread. Unfortunately for the agriculturist, many weedy species reproduce and spread vegetatively as by seed. (3) The order of drought resistant is Common purslane=dayflower>larger crab-grass>amaranth>wild oat>water foxtail=barley>smartweed=oriental cocklebur. (4) Degree of covering depth were influence to control of assimilation and consumption of nutrients by respiration.

The pattern of pH changes in the leaf sap with changes of nutrient solution and soil pH were invstigated. Further studies on the relation between sap pH and the growth and yield of major crops were made. The results obtained are summarized as follows; 1. The sap pH of the terminal, basal and middle leaves of fifteen crops was measured. The average pH of the three different types of the leaves was the same in each crop. 2. Sap pH of corn, soybean and sweet potato showed low acidity in the morning and tended to strengthen in the afternoon. 3. No significant differences of sap pH exsisted between five varieties of sweet potatos tested. 4. Sap pH was slightly affected by the stage of crop growth, there's being tendency towards less acidity in the later stages of growth. A pH difference occured between leaves attached at different places up the stem. 5. Sap pH measurements on major crops(37 species) and weeds (16 species) showed a pH range of 3.83 ∼7.31. When classified into six groups : 19 species had a pH of 5.6 ∼6.0, 17 species a pH of 6.1∼6.5, four species (grape, ginkgo, persimmon, rumex) were below pH 4.5 and eight species (pumpkin, rice, soybean, ramie, perilla, rape, alfalfa and speedwell) showed sap pH above 6.6. 6. When crops (rice, corn, soybean, sweet potato, pumpkin) were cultivated in nutrient solutions different pH, strongly acid and alkaline solutions were neutralized by growth. Dispite this little change was observed in plant leaf sap pH.

Seven varieties of local cowpea (Vigna sinensis) collected from the mainland were examined to evaluate agronomic characters, yield components and productivity. Average flowering date of local cowpea was the 8th of August with earliest variety Gamaegwidongbu and latest variety Soebbuldongbu. Leaf area index (L.A.I.) and suppression of weeds were 7.8 and 86% respectively, indicating vigorous character of cowpea. Maturing time occured on the 14th of September and Soebbuldongbu variety showed latest maturing on the 30th of September. Grain yield per 10a. (kg/10a.) was 288.9kg and highest variety was Hindongbu (41 7.4kg). Higher podding ratio (74.5%) was observed when compared to soybean (25-40%) and leaf sap pH was 6.08. Mean stem length of cowpea was 320 cm, and variety with longest stem was Pangyodongbu of 421cm. Pod length was 17.2 cm and longest in Hindongbu (22.2cm), shortest variety was Najudongbu (12.8cm). Soebbuldongbu showed longest main root length of 181cm and root penetrating depth was upto 65cm from the top soil, and mean root length of cowpea was 135crn. Average number of pod per hill was 28.7 the greatest number was found in Mungokdongbu (39). Num-ber of seed per pod; 16.6 seeds, weight of 1 liter; 754g and weight of 100 grain was 17.4g. Mean seed size was 8.5 mm x 6.4.mm. The seed coat color varies greatly between varieties: brown (Soebbuldongbu), white (Hindongbu, Najudongbu), black (Gamaegwidongbu), pale gray (Pangyodongbu), gray (Mungok-dongbu) and yellowish white color (Suchondongbu).

This studies was carried out to establish production of plug plantlets for mass propagation using stem cuttings of virus free potatoes. Mass propagation of shoot of seedlings was favored in wondergrow compared with MS and hyponex solution culture medium. The higher concentrations of all solution culture media, the higher root formation and shoot growth contributing was. Foliar application wondergrow suitable for seedlings growth were obtained 2,000mg/l concentration. Plug seedlings elongation was promoted by soaked cutting with NAA 1.0~5.0mg/l. Fifty days after transplanting the plug plantlets in vinyl house, plant was 20cm to 30cm in height, and the number of stolons and tubers were ten, respectively. Fresh weight of root was positively correlated with plant height, root length, SPAD reading and number of leaves per plant.
