Abstract

Sweet potatoes are propagated using vegetative propagation, especially cuttings. The cuttings used can come from the shoots and stems. During the distribution to farmers, the cuttings undergo temporary storage that useful to help maintain moisture, temperature, and air circulation in an optimum state. The study aimed to determine the effect of variety, type of cuttings, length of storage, and their interaction on vegetative growth and potential cuttings produced by sweet potato plants. The study was arranged using a three-factor factorial Randomized Block Design with 4 replications. The first factor was sweet potato varieties composed of 2 levels, specifically Antin 3 (V1) and Beta 1 (V2). The second factor is the cuttings types composed of two levels, specifically shoots (S1) and stems (S2). The third factor is the storage period, which consists of 3 levels, specifically without storage (P0), 1 week of storage (P1), and 2 weeks of storage (P2).  The observed variable consisted of cutting growth rate, primary branch length, secondary branch length, and number of branchs and cuttings potential. The results showed that the Beta 1 variety had better growth than the Antin 3 variety based on the criterion  of shoot growth, secondary branch length, and cuttings potential. Beta 1 has a longer shelf life than Antin 3, which can be stored for 1 week. Cuttings planting material storage can reduce all observation criterion, specifically growth capacity, primary branch length, number of branchs, secondary branch length, and cuttings potential. Cuttings derived from the shoots produced better plant length than stem cuttings in the treatment without storage.

Abstract

Shallot development faces an obstacle, specifically the availability of quality seeds. Onion propagation is usually done conventionally with vegetative propagation methods using bulbs as seeds. The aims of study were to determine the effect of the size of the shallot bulb planting material on the growth and production of shallots, to obtain the variables used in selecting the size of the shallot bulbs.The research was conducted at Leuwikopo Experimental Farm in Dramaga, Bogor from February to May 2024. The experiment was conducted by comparing two treatments and each treatment was repeated 9 times. The treatment used was bulb size, especially large and small. The data obtained were tested using the t-student test at the 5% α level, which compares the results of observations between large and small bulbs. The variable observed consisted of plant height, number of shoots, number of leaves, number of bulbs, number of multiplications, wet weight, and dry weight of bulbs. The results showed that different sizes of bulbs used as shallot plant propagation materials affect the growth and production of shallots. Shallot seeds with large bulb sizes produce better growth than small bulbs. The size of large and small bulbs produces output in the form of variable of the number of bulbs per clump, and wet and dry weights of bulbs that are not different. The variables number of leaves, number of shoots, dry bulb weight, and multiplication rate can be used as characteristics for selecting bulb size.
