Efektivitas Re-Cycle Polinasi Melalui Teknik Pemangkasan dan Dosis Pupuk NPK Terhadap Produksi dan Mutu Benih Terung (Solanum melongena L.)

One effort to increase production and quality eggplant seed (Solanum melongena L.) is using Re-cycle pollination technology. This research aims to know production and quality eggplant with applied Re-cycle pollination technology from pruning technique and doses NPK fertilizer. This research held from March to December 2016 in Jatiagung village, Gumukmas, District Jember. The research design used a Randomized Block Design (RBD) Factorial with 2 factors. The first factor was pruning technique consist of leaving 2 segments on branch Y (T 1 ) and pruning leaving 3 segments on branch Y (T 2 ). The second factor was doses NPK fertilizer consists of 120 g/plant (P 1 ), 170 g/plant (P 2 ), 220 g/plant (P 3 ). Observed parameters were total buds, age at 80% flowering, age at 80% harvested, total fruit, total seed, a total of pithy seed, a total of empty seed, production per hectare, germination capacity, germination quality, and seed germination rate. The result from this research showed that pruning technique was only giving a significant effect on the total number of buds. Pruning with leaving 3 segments on branch Y (T 2 ) resulted in 11,83 buds. The treatments of doses NPK fertilizer gave a significant effect (*) on the parameter of  total fruit, weight of 1000 seeds, and seed production per hectare and given a very significant effect (**) on parameter of total number of buds, age at 80% flowering, age at 80% harvested, total empty seed per fruit, and germination capacity. Doses of NPK fertilizer 170 g/plant (P 2 ) has a higher resulted is 2,7148 kW/ha. Togetherness the two treatments were showed not a significant effect to all the observed parameters.
