Abstract

The purpose of this research is to determine the influence of interaction between organic growth regulator concentration and immersion duration time, as well as the influence of each of these factors on germination sugarcane (Saccharum officinarum L)cuttings. This study uses a randomized group design (RAK) with two factors, immersion duration (P)in 4 levels of P1 (1 minute), P2 (2 min), P 3 (3minutes), and P4 (4 minutes) and two levels of organic plant growth regulator (K), 4 cc/ liter, and 5 cc per liter of water, each treatment is repeated 3 times to obtain 24 treatments. The results reveals that a)There is a significant interaction effect due to immersion duration and concentrations of organic growth regulator to the observed variables: number of roots per plant, root length per plant, gross weight per plant and net weight per plant at the end of the observation b). Each factor of both immersion and concentration of organic plant growth provide significant influence on all the variables studied. 0). The highest value on all the variables observed is achieved by K2P4 treatment with concentration of 5 cc/liter and 4 minutes immersion; yet statistically, the optimum value is achieved by treatment K2P3 or influence of K2 and P3treatment.

Abstract

The research objective was to determine the effect of NPK compound fertilizer dosage on the growth and yield of purple eggplant (Solanum melongena L). The research was carried out at the Nursery, Agribusiness Sub-Terminal, Food Security and Agriculture Service of Surabaya City, on Jl. Ketintang Madya VII Surabaya, East Java with an altitude of ± 5 m above sea level. Conducted from April to June 2018. his study used a randomized block design (RBD) consisting of six dose treatments with three replications and two sample plants. The NPK compound fertilizer dosage treatment included: D0 = without NPK (Control); D1 = NPK 100 kg / Ha; D2 = NPK dose of 200 kg / ha; D3 = NPK dose of 300 kg / ha; D4 = NPK dosage 400 kg / ha; D5 = NPK dose of 500 kg / ha.The conclusion of the study, namely the NPK dose treatment had a very significant effect on plant height, number of leaves, number of fruits and wet weight per plant of purple eggplant (Solanum melongena L). Treatment with NPK dose of 500 kg / Ha showed the highest growth and yield, although statistically it was not significantly different from the NPK treatment dose of 400 kg / Ha and the NPK treatment dose of 300 kg / Ha (optimum dose).
