Abstract

Riyadi Pratiwa Sutardjo. Increased Growth and Yield and Quality of Shallot (Allium ascalonicum L.) Through ZA Fertilization and Manure at Different Distances Planted In Deli Serdang District. Under his guidance, Prof.. Dr. Ir. Rosmayati, MS., as Chairman of the Commission of Advisors with member Dr. Ir. Hamidah Hanum MP. This study aims to determine the dose of ZA, the dose of cattle manure, and plant spacing to improve growth, yield and quality of shallot plants. The experiment was conducted at the College of Agricultural Extension (STPP) Medan Deli Serdang regency of North Sumatra Province, from January until April 2010. The research method used was the Split Split Plot Designs with three (3) factors and three (3) replications. The main plot is the spacing (A) consists of three (3) treatment, namely: a spacing of 20 x 10 cm (J1), spacing of 20 x 20 cm (J2), and spacing of 20 x 30 (J3). The subplot is cattle manure (K) consisting of: without cattle manure (K0), cattle manure 10 tonnes / ha (K1), cattle manure 20 tonnes / ha (K2), and cattle manure 30 tonnes / ha (K3). A sub-subplot is: without ZA (P0), ZA 150 kg / ha (P1), ZA 300 kg / ha (P2), and ZA 450 kg / ha (P3). The results showed ZA fertilizer application did not increase growth and yield of shallot, but trend to increase the aromatic of the shallot flavor. Cattle manure application did not increase growth and yield of shallot, except cattle manure up to a dose of 10 tonnes / ha increased plant height at 4 and 6 After Week Planted (AWP) and trends to increase the aromatic of the shallot flavor. The treatment plant spacing did not increase growth but increased yield of shallot, which is indicated by the weight of wet and dry weight of the highest achieved in the arrangement spacing of 20 x 10 cm.
