Abstract

Alar is a growth regulator that in certain concentrations can inhibit growth, shorten stem segments, strengthen stems to improve the quality of tissue-cultured seedlings. This study aimed to determine the effect of alar and Benzyl Adenin (BA) on banana meristem multiplication. The experiment was conducted in Tissue Culture Laboratory, Faculty of Agriculture, Tribhuwana Tunggadewi University, Malang. The study used a Completely Randomized Design consisting of two factors, namely alar concentration (A0 = 0 mg/l and A1 = 1 mg/l) and BA concentration (B1 = 1 mg/l, B2 = 3 mg/l, B3 = 5 mg/l and B4 = 7 mg/l). Observations were made for 12 weeks of culturing with the observation variables: shoot initiation, number of shoots/explants, number of leaves, and shoot height. The results showed that alar and BA did not significantly affect the development of banana meristems. The use of Alar caused the banana plantlets to be shorter and sturdy, while BA affected the number of shoots produced. BA 1 mg/l was able to increase more shoots.

Abstract

Increasing the growth and production of waxy corn can be done by fertilizing. This study examined the effect of N-Leucaena leucocephala and P-rock phosphate enriched manure that was called manure plus, on the growth and production of waxy corn. The study used a randomized block design (RBD) with five treatments and six replicated namely T0 (urea + TSP), T1 (cow manure + urea + TSP), T2 (goat manure + urea + TSP), T3 (cow manure plus), and T4 (goat manure plus) with five treatments and six replicates. Parameters measured were plant height, leaves number, stem diameter, chlorophyll levels, waxy corn production, and dry matter production of stover. The results showed that stem diameter, chlorophyll, waxy corn production, and dry matter production of stover in cow manure plus and goat manure plus was equivalent to cow manure + urea + TSP and goat manure + urea + TSP, respectively. The number of leaves in the goat manure + urea + TSP treatment is higher compared to goat manure plus. However, plant height was not significantly affected by the treatments.

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.
