GROWTH RESPONSE OF CELERY PLANT (Apium graveolens L.) AGAINST THE COMBINED APPLICATION OF LIQUID ORGANIC FERTILIZER AND COMPOST FERTILIZER

2023-07-03

The purpose of this study was to analyze the growth of celery (Apium graveolens L.) in the application of a combination dose of liquid organic fertilizer and compost. This research was conducted at the Screen House Laboratory of Agrotechnology, Faculty of Agriculture, Musamus University, Merauke in June-September 2018. This study used a factorial randomized block design (RAKF). The first factor is compost and the second factor consists of liquid organic fertilizer. The two factors after being combined obtained 16 treatments which were repeated 3 times to obtain 48 treatment units. Based on the results of the study, it was concluded that the analysis of the growth variance of celery on the application of a combination dose of liquid organic fertilizer and compost showed no significant effect. On the variable plant height, the combination treatment of A3N3 (compost 60 g/plant and POC 4 ml/liter) gave the highest plant height of 26.00 cm, the variable number of leaf stalks in the A3N0 treatment (compost 60 g/plant and POC 0 ml/liter) gave The result of the number of petioles was 14.33 strands, and the variable number of tillers of A3N0 treatment plants (60 g compost/plant and 4 ml POC/liter) gave 2.67 tillers.

TOXICITY COMPARISON OF NEEM LEAF EXTRACT (Azadirachta indica A.Juss) AND MINDI LEAF (Melia azedarach) FROM MERAUKE ORIGIN AGAINST Plutella xylostella larvae

2023-07-03

Plutella xylostella is a major pest on cabbage plants. At times of hight population numbers, the
larvae will eat all the leaves and leave only the bones of the leaves, this will cause severe damage,
thereby reducing production yields. The result are quickly seen despite the negative impact, as a
result the crops that should be of hight quality and nutrition become contaminated with chemical
pesticide residues and are dangerous if consumed. The results showed that the highest mortality
was in the single test of neem leaf extract, which was 57% and the highest mortality was in the
mindi leaf extract which was 33%.

ADAPTATION TEST OF RICE STRAINS (Oryza sativa L.) ON SALINE FIELDS IN BOKEM VILLAGE, MERAUKE DISTRICT

2023-07-03

This study aims to analyze the adaptability of 2 new lines of rice tested in saline soils. This research was carried out for 3 months, from June to August 2018, in Bokem Village, Merauke District. This study used a randomized block design (RBD) using 2 new rice lines and 2 varieties, namely Mekongga and Inpari 35 varieties. The number of treatments used in this study were 4 treatments with 4 replications. The number of experimental plots is 16 plots. The results showed that 2 new rice lines adapted to the vegetative and generative phases, i.e., line 1 had an effect on plant height (14 and 35 days after planting), number of tillers (14 days after planting and 35 days after planting) and flowering age (65 days after planting), and line 2 had an effect on productive tillers variable (12.9), 1000 grain weight (25.20) and ton/ha (4.60 kg).

Adaptation Test of 3 Rice Strains (Oryza Sativa L.) By Using Two Comparison Varieties, Inpari 35 and Mekongga in Salin Land, Bokem Village, Merauke District

2023-07-08

The purpose of this study was to analyze the adaptation or adaptation of the 3 (three) rice lines tested with 2 (two) control varieties on saline soils in Kampung Bokem. The use of tolerant varieties is one of the most effective ways to exploit the potential of saline soils in an effort to increase national rice production. The area of saline land in Asia is around 21.5 million ha, of which 12 million ha are saline and 9.5 million ha are alkaline. This research was carried out using a randomized block design (RBD), using 5 (five) treatments and repeated 4 times so that 20 experimental units were obtained. Based on the results of the study, there were no strains that died due to salinity stress. This indicated that all of the lines included in this experiment were considered to be quite tolerant to salinity. The best growth line is line 10 with a number of productive tillers of 20.03 stems and the best production is line 5 with a production of 4.75 tonnes/ha.

ADAPTATION TEST 2 STRAINS OF RICE (Oryza sativa L.) ON SALINE LAND IN BOKEM VILLAGE

2023-07-08

Merauke is one of the centers of rice cultivation in Papua, which has several tidal swamp areas that contain salt in the soil or saline, but their utilization could be better. From this, it is necessary to test the adaptation of new rice lines on saline soils so that they can provide information about their adaptability from the plant growth process to the level of production. This study found that the new rice lines adapted quite well physiologically and morphologically to the salinity stress area where they were tested.
