Abstract

The availability of superior sugarcane varieties is one of the causes of the low national sugarcane production. The results of mutations from Bululawang sugarcane (BL) variety obtained three genotypes that have the potential to have high yields. Sugarcane plants can be cultivated in all locations because sugarcane can be grown in tropical and subtropical areas with the main problem of water availability being either shortage (drought) or excess (poor drainage). Increases and differences in sugarcane yields can be caused by fertilization, good water distribution throughout the sugarcane growth cycle, crop management, climate and different varieties. if the plant does not experience a lack of water, its production can reach 123 ton/ha/year, but if the plant is under moderate stress (4-5 weeks without rain) then the production will drop to 108 Ton/ha/year. Therefore, it is necessary to conduct a study to determine the potential of each mutant sugarcane at different locations. This research uses direct observation method to each location. Then the data obtained was analyzed descriptively analytically to provide an overview of the object under study through the data that has been collected as it is without analyzing and making conclusions that apply to the public. The results of the research that the M1 mutant sugarcane had the age of emergence of tillers, the highest number of tillers and was able to adapt very well at an altitude of ± 512 meters above sea level. The M1 mutant sugarcane has the highest plant height, the highest number of segments and is able to adapt very well at an altitude of ±62 meters above sea level. The M2 mutant sugarcane has the highest internode length and is able to adapt very well at an altitude of ±62 meters above sea level. Sugarcane M3 has the stem diameter, the highest internode length and is able to adapt very well to an altitude of ± 512 m asl.Key words: sugarcane; production; mutation; different varieties

Abstract

Melon has high potential and economic value and has been developed in various fields such as plant breeding, cultivation technology, and the creation of new varieties. Proper cultivation and maintenance techniques are one of the efforts to increase melon crop production through fertilizing with the right type of fertilizer and dosage and concentration. Information on the use of NPK fertilizer and Growmore Fertilizer to increase the diameter, thickness, and weight of melon fruit has not been found. Therefore, this study aimed to increase the diameter, thickness, and weight of melon fruit. This research was expected to get a better diameter, thickness, and weight of melon. This research was conducted in the experimental garden of the Muhammadiyah University of Jember. Research implementation began in January 2023 with an altitude of ± 98 m asl. This study used a randomized block design (RBD) with two factors and three replications, namely: NPK fertilizer: P0 = 0 g/plant (control), P1 = 600 kg/ha (15 g/plant), P2 = 800 kg/ha (20 g /plant). Growmore leaf ertilizer N0 = 0 g/l (control), N1 = 3 g/l, N2 = 4 g/l (125 ml/plant). Observational variables consisted of: planted fruit weight (kg), fruit weight per plot (kg), fruit diameter (mm), and flesh thickness (mm). In the variables of planting fruit weight and fruit weight per treatment plot that gave the highest yields were P1 with yields of 1.14 kg and 7.52 kg, N2 with yields of 1.09 kg and 6.68 kg, and P1N2 interactions gave the highest yields of 1 .28 kg and 8.20 kg. The variable diameter of the treated fruit that gave the highest yield was P1 with a yield of (24.30 mm) N2 with a yield of (23.09 mm and the P1N2 interaction gave the highest yield of 127.89 mm. On the variable thickness of the treated fruit, the highest yield was P2 with a yield of (5.47 mm, N2 with a yield of (4.61 mm), and P1N2 interaction gave the highest yield of 38.00 mm.   Key words: diameter; thickness; melon fruit; NPK; growmore
