Local rice germplasm may play an important role in improving rice quality. One of the important to improve rice cultivar trait is days to flowering. Ponorogo is one of district of center rice production area where the farmers cultivate local rice varieties which is early days to flowering or short vegetative phase. Exploration of local early days to flowering rice accessions in Ponorogo resulted in 9 accessions. Flowering times ranged 51 to 91 days after sowing. Based on morphological variation, there were variation of plant height, number of leaves, number of tiller, number of panicle, number of grains per panicle, flowering time, grain size and weight of 100 grains. Morphological dendrogram made possible to identify three groups at similarity 0.88.

Ginger plant is a medicinal plant widely cultivated by farmers, especially in Pandeglang regency. This research was aimed to find out the relationship of local ginger based on morphological characteristics as well as to dig up information about e×isting varieties so that it can be a reference for plant breeding of local ginger in Pandeglang regency. The research was conducted in a way of e×ploration from October to November 2021 in Bojong, Menes, Cisata and Majasari sub-districts as the location of accession. 3 samples were taken from each accession so that the total of sample was 12 observation samples. The relationship of kinship was observed with the SPSS program of cluster analysis. The results showed that in Pandeglang were e×plored 2 types of ginger planted, namely red ginger and small white ginger (emprit), scattered in all accessions. Based on the morphological characteristics, the two types of ginger had similarities on the shape of stem, the color of stem, the shape of leaf, the tip of leaf, the base of leaf, and the shape of root. It was found that the closest kinship relationship was in the sample A1 with A2 with a coefficient value of 3.733 and the furthest kinship was found in the sample A1 with C3 with a coefficient value of 24.499. Thus it can be known that there is a close kinship relationship between ginger plants in Pandeglang Regency.

This research aimed to determine the effect of several varieties on different populations on the growth and yield of shallot (Allium ascalonicum L.) from botanical seeds (True Shallot Seed). This research was an experimental research conducted from August to October 2021 in the integrated farming system area, Serang, Banten. This research was laid out in a factorial randomized block design (RCBD) consisting of two factors. The first factor was the differences in varieties consist of 3 levels, namely Maserati (v1), Sanren (v2), and Tuk-Tuk (v3). The second factor was the population which consists of 4 levels, namely the population of 1 plant (p0), 2 plants (p1), 3 plants (p2), and 4 plants (p3). The results showed that there was an interaction between the varieties and populations on the parameters of fresh weight of bulbs/plant, the combination of Maserati variety with 1 population (40.32g). The Sanren variety gave the best effect on the parameters of bulbs/plant (1.92 bulbs).

Evaluation of Arbuscular Mycorrhizae Fungi application on shallot (Allium cepa L. aggregatum group) is extremely important to instead of Phosphorus synthetic fertilizer. The experiment was laid out in randomized completely block design with three replications as block. The experiment consisted of Arbuscular Mycorrhizae Fungi (AMF) application, AMF and Phosphorus application, Phosphorus application and without any treatment. The experiment resulted that there were no difference on plant height and number of leaves among treatments. In total chlorophyll content, AMF application is lower than Phosphorus synthetic application. In contrast, AMF application was showed the highest of yield.
