Pengaruh Pemberian Arang Sekam Padi Dan Pupuk NPK Pak Tani Terhadap Pertumbuhan Dan Hasil Tanaman Terung Ungu (Solanum melongena L.) Pada Tanah Aluvial Di Polybag

Abstrak

This study aims to determine the effect of the interaction of rice husk charcoal and NPK Pak Tani fertilizer on the growth and yield of eggplant plants (Solanum melogena L.) on alluvial soils in polybags. This research was conducted on Jalan Karet, Gang Karet Merdeka city, West Pontianak, West Kalimantan Province, with a height of 5 meters above sea level. This research was carried out from March 03 to August 07, 2021. This study used a Complete Randomized Design (RAL), with a factorial pattern. The treatment consists of 2 factors, namely: the first factor is Rice Husk charcoal and the second factor is Pak Tani's NPK fertilizer. The first factor is Rice Husk charcoal with code (B) consists of 3 levels of treatment, namely: b1 = rice husk charcoal with a dose of 50 grams / polybag, b2 = rice husk charcoal with a dose of 100 grams / polybag, and b3 = rice husk charcoal dose 150 grams / polybag. The second factor is NPK Pak Tani fertilizer with code (S) consisting of 3 levels of treatment, namely: s1 = NPK Pak Tani fertilizer with a dose of 1.5 grams / polybag, s2 = NPK Pak Tani fertilizer with a dose of 2 grams / polybag, and s3 = NPK Pak Tani fertilizer with a dose of 2.5 grams / polybag. Thus there are 9 treatment combinations of b1s1, b1s2, b1s3, b2s1, b2s2, b2s3, b3s1, b3s2, b3s3. Each treatment was repeated 3 times with 3 plant samples, then the number of plants used in the study was 3 x 3 x 3 x 3 = 81 plants. The results showed that the influence of rice husk charcoal and NPK Pak Tani fertilizer, both interactions and treatments, each had a single unreal effect on all variables of eggplant plant observation, namely: plant height, number of leaves, number of planting fruits, length of planting fruits and weight of planting fruits. In the combination of treatments (b1s3) produced the highest average plant height of 51.68 cm. The combination of treatments (b3s1) resulted in an average of the highest number of plant leaves of 36.67 strands. The combination of treatments (b2s2) resulted in the highest average number of fruits per plant of 1.39 pieces. The combination of treatments (b3s2) resulted in an average fruit length per highest plant of 13.48 cm. And the combination of treatments (b3s2) resulted in the highest average fruit weight per plant of 90.09 grams.
