Abstract

This study aims to determine of knowing the effect of the intensity of sun radiation and the right nitrogen fertilizer on the growth of the highest chinese cabbage. The research has been carried out in Wirogunan Village, Kec. Purworejo Pasuruan City was conducted from September to December 2021. This study used a Divided Plot Design (RPT) which was repeated three times. The intensity of sun radiation is placed as the main plot (P) which consists of three levels: : 55% sun radiation intensity, : 65% sun radiation intensity, : 75% sun radiation intensity. Nitrogen fertilizer doses were placed as subplots (J) which consisted of three levels: : Nitrogen fertilizer dose 200 kg ha-1, : Nitrogen fertilizer dose 300 kg ha-1, : Nitrogen fertilizer dose of 400 kg ha-1. From the two treatments, 9 treatment combinations were obtained and each treatment was repeated three times to obtain 27 treatment combination units. The results showed that the treatment of 65% sun radiation intensity and nitrogen fertilizer 300 kg ha-1 resulted in the highest plant growth and yield. Chinese cabbage treatment with 65% sun radiation intensity and nitrogen fertilizer 300 kg ha-1 resulted in fresh weight ha-1 of 53,61 tons.

Abstract

Bitter mustard, known as salty mustard or green mustard, is one of the most popular vegetable commodities and has high economic value. Trichocompost is an alternative to increase the growth of mustard greens. This study aims to determine the appropriate dose of goat kohe trichocompost fertilizer to produce high growth and production of mustard greens. Completely randomized design with four treatments, namely M0 : control, M1 : 100 gr.plant-1, M2 : 120 gr.plant-1 and M3 : 140 gr.plant-1 repeated four times. The results of the study concluded that the application of goat trichocompost kohe fertilizer had a significant effect on plant height, number of leaves, leaf area, fresh weight, and dry weight of bitter mustard plants. The best dosage of goat kohe trichocompost fertilizer that can increase the growth and productivity of bitter mustard plants is a dose of 140 gr.plant-1.
