Abstract

ABSTRACT  The objective of this research was to know growth and the production of watermelon plants through the treatment of pruning time on shoots and the amount of residual fruit after thinning. The research was carried out on Klaten Watermelon Clay, located in Genukan Village, Wedi Sub-district, Klaten District, and at the Laboratory Chemistry and Food Nutrition Faculty of Animal and Agricultural Sciences, Diponegoro University from February to May 2017. The research was arranged using completely randomized factorial design with the first factor being shoot pruning time (P1 = no trimming, P2 = 3rd week, P3 = 6th week, P4 = 3rd and 6th week) and the second factor was the rest of the fruit after thinning (Q1 = without thinning, Q2 = thinning leaves 1 piece, Q3 = thinning leaves 2 pieces). The results showed the treatment of pruning of shoots and the remaining fruit after spacing did not affect the growth plant height and number of leaves watermelon until 8th week. However pruning of shoots 3rd week and 6th week can affect fruit diameter, fresh fruit weight, and fruit sugar levels. Treatment of the remaining fruit after the spacing is pruned 2 pieces affect the diameter of fruit and fresh weight of fruit while the rest of the fruit after spacing is purned 1 pieces fruit affect the fruit sugar levels. Keywords: watermelon, pruning, thinning, production ABSTRAK  Penelitian bertujuan untuk mengetahui pertumbuhan dan hasil produksi tanaman buah semangka melalui perlakuan waktupemangkasan pada pucuk dan jumlah sisa buah setelah penjarangan.

Abstract

 The purpose of the research was to study the concentration of NaOCl and drying method during the extraction process for germination and growth of tomato seedlings. This study used Completely Randomized Design with two factors with three replicates. The first factor was soaking the seeds with NaOCl concentrations: NaOCl 0% (control), NaOCl 6%, NaOCl 9% and NaOCl 13%. The second factor was the drying methods: without drying (control), natural drying and drying using oven. The parameters observed were germination, seed growth rate, maximum growth potential, leaf size, leaf area, plant height, plant growth rate and relative plant growth rate. The data were analyzed using variance analysis and continued by Duncan Multiple Range Test (DMRT) of 5%. The result of variance analysis showed that immersion treatment using NaOCl and drying method had not given interaction during seed germination and seedling growth. Soaking with 9% NaOCl showed the best result of germination process and seedling growth whereas the best drying method was naturally because it did not cause impermeability of seeds.
