Abstract

Pemangkasan pucuk merupakan upaya penyeimbangan pertumbuhan vegetatif dan generatif pada tanaman Indeterminate seperti tanaman mentimun. Penyeimbangan pertumbuhan tanaman berperan dalam efisiensi aliran fotosintat tanaman. Usaha perbaikan kualitas produksi benih mentimun dilakukan dengan melakukan efisiensi aliran fotosintat dan peningkatan unsur hara esensial yang terlibat dalam proses pengisian biji. Unsur hara kalium memiliki peranan yang penting dalam proses pengisian biji tanaman mentimun. Percobaan ini dilakukan untuk mengetahui pengaruh pemangkasan pucuk dan dosis pupuk kalium terhadap produksi dan kualitas benih mentimun. Percobaan dilakukan menggunakan Rancangan Acak Kelompok (RAK) Faktorial terdiri dari 12 kombinasi perlakuan pemangkasan pucuk dan dosis pupuk kalium dengan 3 ulangan. Hasil percobaan menunjukkan bahwa kombinasi perlakuan pemangkasan pucuk dan dosis pupuk kalium berpengaruh terhadap produksi dan kualitas benih mentimun yaitu pada variabel jumlah biji, presentase biji bernas dan berat buah. Pemangkasan pucuk ruas ke 12 dan dosis pupuk kalium 300 kg/ha mampu memberikan hasil terbaik. Kata kunci : Pemangkasan Pucuk, Kalium, Produksi dan Kualitas Benih.

Abstract

Phosphorus (P) is one of the essential nutrients that functions is metabolism in plant. Based on these functions, it indicates that nutrient P has an important role for plant growth and production. However, its availability in soil is very low, which is less than 0.01% of the total P. Therefore, the availability of P nutrients in the soil needs to be increased by increasing the activity of soil microorganisms through the use of phosphate solubilization bacteria. This research is aimed to show the changes in the physiological characteristics of tomato plants through the application of phosphate solubilization bacteria and rock phosphate. Experiment using factorial randomized block design (RBD) which consisted of 2 factors with 2 consultation levels on the first factor (phosphate solubilization bacteria) and 4 levels on the second factor (rock phosphate), and it consist of 8 combinationed of phosphate solubilization bacteria and rock phosphate with 3 replicated. The results showed that the combination treatment of phosphate solubilization bacteria and rock phosphate affected the physiological characteristics of tomato plants, especially on the variables of stomata density, leaf chlorophyll, plant height, plant dry weight, fruit weight and plant P-tissue content in the vegetative final phase. The recommendation of an efficient fertilizer combination to improve physiological characteristics and high yields is use the phosphate solubilization bacteria and rock phosphate 0.69 grams Keywords: phosphate solubilization bacteria, physiological characteristic, rock phosphate
