Abstract

The study was conducted at experimantal field at Faculty of Agriculture, Asahan University, Asahan Regency on October 2020 until December 2020. The study aims to the find out the growth response and production of shallots (Allium cepa L.) to the concentration of coconut water and growth media veticulture. This study used randomized complete block design with two factors: (1) Concentration of coconut water (K) with 3 levels: K1 = 25% (250 ml coconut water + 750 ml water), K2 = 50% (500 ml coconut water + 500 ml water), K3 = 75% (750 ml coconut water + 250 ml water) and (2) growth media (M) with 3 levels: M1 = soil + cow manure (1:1), M2 = soil + cow manure (2:1), M3 = soil + cow manure (3:1). Observation parameters were plant height, number of leave, number of bulbs, bulbs weight. The results showed that coconut water concentration had a significant effect on the number of tubers per clump and tuber wet weight, but had no significant effect on observations. plant height and number of leaves, the best treatment at K3 = 75% (750 ml coconut water + 250 ml water). The planting medium did not significantly affect the observations of plant height, number of leaves, number of tubers per clump and wet weight of tubers. The interaction between the concentration of coconut water and growing media did not have a significant effect on all observed variables.

Abstract

This research was carried out at Durian street, Kisaran Naga Village, Kisaran Timur, AsahanDistrict, North Sumatera. The study was conducted in April to June 2017. This research wasarranged based on Factorial Randomized Block Design with 2 treatment factors and 3replications. The first factor was cutting of tubers with 4 levels ie: P0 = without cutting tuber, P1 = cutting tuber of 1/3 of shoot, P2 = cutting tuber of 1/4 of shoot, and P3 = cutting tuber of 1/5 of part shoots. The second factor of plant density with 3 levels of spacing is J1 = 20 cm x 10 cm, J2= 20 cm x 15 cm, and J3 = 20 cm x 10 cm. The results showed that tuber cutting treatment had significant effect on all observed variables, whereas cutting of tuber 1/3 of shoot (P1) was the best treatment. Treatment of plant density had significant effect on all observed variables, where the density with plant spacing of 20 cm x 20 cm (J3) was the best treatment. The interaction between tuber cutting and plant density had no significant effect on all observed variables.

Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) Faktorial dengan dua faktor dan empat ulangan. Faktor pertama adalah media tanam terdiri dari 2 taraf yaitu M1 = tanah 100%, M2 = tanah + pupuk kandang 50% : 50%. Faktor yang kedua POC NASA terdiri dari 3 taraf yaitu P0 = 0 cc/l air/bibit, P1 = 2 cc/l air/bibit, P2 = 4 cc/l air/bibit. Peubah amatan yang diamati adalah pertambahan tinggi tanaman (cm), pertambahan jumlah daun (helai), pertambahan diameter batang (mm). Analisis keragaman menunjukkan bahwa tidak ada pengaruh media tanam terhadap pertambahan tinggi tanaman, pertambahan jumlah daun dan pertambahan diameter batang bibit gaharu pada umur 9 MST. Ada pengaruh POC NASA terhadap pertambahan tinggi tanaman dan pertambahan jumlah daun bibit gaharu pada umur 9 MST.
