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

This research aimed to see the effect of the addition of NAA and BA into MS media for the development of cassava micropropagation, furthermore, the composition of the media was appropriate to produce the maximum number of cassava shoots. The study was conducted using a completely randomized factorial design consisting of 2 factors, namely: Factor I: the concentration of Naphthalene Acetic Acid (NAA) consisted of 2 levels, namely: 0 mg / l (N0) and 0.1 mg / l (N1). The second factor was the concentration of Benzyl Adenine (BA) consisting of 4 levels: 1.0 mg / l (B1); 3.0 mg / l (B2); 5.0 mg / l (B3) and 7.0 mg / l (B4). Apply 8 treatment combinations, N0B1; N0B2; N0B3, N0B4, N1B1; N1B2; N1B3; N1B4. Observations were made on the variables: time of shoot initiation, number of shoots, number of leaves, and percentage of live and contaminated explants until the age of 16 weeks after sub-culture. The results showed that there was no interaction between the addition of the auxin hormone NAA and the cytokinin BA into MS medium at the time of shoot initiation, but both hormones could support the number of new shoots and the number of leaves per plantlet. Media without the addition of NAA with the addition of BA 1.0 - 3.0 mg / l was able to initiate new shoots the fastest, namely 7-10 days. The best number of shoots of cassava (4.43 shoots/explant) used MS medium without the addition of NAA with BA 3.0 mg / l for 16 weeks (4 months) of culture.

Abstract

The development of horticultural commodities is quite beneficial because it is supported by the potential of natural resources, human resources, availability of technology, and market absorption, one of which is red chili. This study aims to analyze the factors that influence the production of red chili farming in the Sumberejo village and the efficiency of the use of production factors (land area, seeds, manure, TSP, NPK, urea, labor, and pesticides). The data analysis method used is the Cobb-Douglas production function using multiple regression analysis, validity and reliability tests, classical assumption tests, model suitability (goodness of fit model), and efficiency analysis. The results showed that the simultaneous use of production factors of land area, seeds, manure, TSP, NPK, urea, labor, and pesticides had a significant effect on the production of red chili. Partially, the land area and seed production factors have a significant effect on the production of red chilies, while manure, TSP, NPK, urea, labor, and pesticides have no significant effect on the production of red chili. The results of the efficiency analysis show that the production factors of land area, seeds, manure, urea fertilizer, and labor are technically efficient because they are located in a rational area and technically, TSP, NPK, and pesticides are not efficient. In terms of price efficiency, the use of production factors is not efficient for land area, seeds, TSP fertilizers, NPK fertilizers, and pesticides have not reached economic efficiency. Other production factors such as manure, urea fertilizer, and labor are not economically efficient, so the use of inputs must be added to obtain maximum production.
