Abstract

The requirements for rice as the staple food in Indonesia tends to increase every year along with the increase in population. As anticipation, an alternative that can be taken is to increase the productivity of carbohydrate-producing crops as the main non-rice food source on dry land. Sorghum is a versatile plant that can be used as a source of food, animal feed, and industrial raw materials. The purpose of this study was to determine the production of 3 varieties of sorghum to reduce the dose of NPK fertilizer. The research was conducted in Sumber Agung Village, Plosoklaten, Kediri Regency in May-August 2020. The research used a factorial randomized block design with the first factor being 3 varieties of sorghum, namely Kawali, Numbu, and Suri 4, the second factor was the dose of NPK fertilizer, which was 100%, 75 %, 50%, 25%, and 0%. The results showed an interaction between sorghum varieties and fertilization doses. Kawali variety only produces maximum if fertilization is 100%, Numbu variety still produces maximum at 50% fertilization and Suri 4 variety can still produce maximum at 25% fertilization.

Abstract

Sorghum is a suitable crop grown in dry and nutrient-poor areas. So it is suitable to be developed in dry and marginal land areas. However, in the cultivation of sorghum on dry land and lack of nutrients, it still needs the effort to increase the yield. This study aimed was to determine the response of sorghum plants to the application of Trichoderma sp. and fertilizer dosage. Treatments tested in this study were with the first factor being the application of Trichoderma and the second factor being the fertilizer dose of 50%, 40%, 30%. 20%, 10% and 0%. The results showed that the treatment has no interaction between Trichoderma application and fertilizer dosage. However, the fertilizer dose had a significant effect on all observation parameters. A fertilizer dose of 40% provides the most effective and efficient results to support the growth and production of sorghum plants.

Abstract

The aimed this study was to determine the effect of rabbit urine liquid organic fertilizer on N uptake, growth, and yield of pakcoy plants and to determine the dose of rabbit urine liquid organic fertilizer on pakcoy plants. This research used a randomized block design which repeated four times. Treatment factor: administration of rabbit urine concentration consisting of 6 treatments: U0 = 0 ml/Plant (Control or no treatment), U1 = 25 ml/Plant, U2 = 30 ml/Plant, U3 = 35 ml/Plant, U4 = 40 ml/ Plant, U5 = 45 ml/ Plant. Two phases of observation parameters were observed in this study, namely the vegetative phase which includes the height of the pakcoy plants in cm units, the number of pakcoy leaves (strands), and the area of the leaves using the length x width times the constant method. The generative phase was observed fresh weight of the plants and the total N uptake at harvest. There are significant differences in the parameters of plant height, number of leaves, and leaf area. Meanwhile, there was no significant difference in the fresh weight of the plants. There were differences in the percentage of nitrogen uptake in each treatment, the highest uptake was in treatment U5, namely using rabbit urine 45 ml/plant, and the lowest in treatment U4, namely using rabbit urine 40 ml/plant.
