THE INFLUENCE OF THE NUMBER OF SEEDS OF HOUSEHOLD AND DOSAGE OF COW MANAGE ON THE GROWTH AND PRODUCTION OF LAND KANGKONG (IPOMOEA REPTANS POIR.)

Abstrak

This study aims to determine the exact number of perforated seeds and the dose of cow manure on the growth and yield of Rajawali variety of land kale. This research was conducted on Jalan Simalingkar Raya, Kec. Medan Tuntungan, Medan City, North Sumatra Province.From April 25 to May 31, 2022. This study used a factorial Randomized Block Design (RAK) consisting of 2 treatment factors with symbol B consisting of 3 levels, namely: B1 (2 perforated seeds), B2 (3 perforated seeds), B3 ( 4 perforated seeds). The two doses of cow manure with the symbol S consist of 4 levels, namely; S0 Control (without fertilizer), S1 (200 gr/plot), S2 (300 gr/plot), S3 (400 gr/plot). so that 12 treatments were obtained. Each treatment was repeated 2 times. The observation data was then analyzed for variance with the F test at 5% level. If the difference was significant, then the test was continued with the DMRT test. The results showed that the treatment of the number of seeds had a very significant effect on plant height, number of leaves, leaf length, leaf width, and fresh weight harvested by land kale. Treatment with cow manure had a very significant effect on plant height, number of leaves, leaf length, leaf width, and fresh weight of kale.
