Abstract

Sunflower seeds are the second largest producer of vegetable oil in the world. Sunflower seeds production ranks third in the world after peanuts and soybeans. Efforts to increase sunflower growth are through cultivation techniques including fertilization with the right dosage and treatment in the form of defoliation. Defoliation aims to increase the intensity of sunlight that can be received by plants, so that it will increase crop yields. Decreasing the intensity of sunlight can reduce yields by 40%. This research was conducted using the experimental method which was arranged in a factorial manner in a Completely Randomized Block Design. The first factor was the Professional NPK dose which consisted of two levels including the recommended dose (P1) and half the suggested dose (P2). The second factor is defoliation time which consists of three levels including phase R1, phase R2, and phase R3. The number of leaves removed is 30% of the number of leaves. The results showed that (1) the half recommended dose of NPK Professional in phase R3 had an effect on the variables of plant height and number of leaves and the recommended dose of Professional NPK had an effect on stem fresh weight; (2) The recommended dose of Professional NPK effects the variables of stem diameter and flower diameter in R2 phase, the recommended dose of Professional NPK affects root dry weight in R2 phase, and the weight of 100 seeds in R1 phase. (3) There is an interaction between the dosage of NPK Professional and defoliation time of sunflower plants. Keywords : Sunflower, NPK, Defoliation

Abstract

Ginger production has decreased over the past year and this could be due to less than optimal plant cultivation. Selection of quality seeds and optimal standards will provide optimal production impacts. Early detection of pathogens in ginger seeds can be an effort to maintain production potential. The aim of this research is to identify the diversity of ginger pathogens that appear in nurseries as an effort to maintain the production potential of ginger plants. This research looked at the pathogens that appeared in red ginger, emprit ginger and elephant ginger which were sown in burlap sacks for one month. Disease symptoms that appear during observation were observed and isolated and were identified the pathogen. Observation results showed that red ginger's healthy rhizome was higher than other ginger. Pathogens identified in three types of ginger include Sclerotium rolfsii, Penicillium sp and Aspergillus sp. Sclerotium rolfsii is the dominant pathogen and has a high attack rate on elephant ginger clones. Keywords: Sclerotium rolfsii, Zingiberales officinale, Rhizome

Abstract

Watermelon (Citrullus lanatus) is a high-value crop that has been commercially cultivated both in the world and in Indonesia. Many factors affect the productivity of watermelon plants such as land use frequency and plant disease attack. The purpose of this study was to determine the severity of disease in 2 fields with different frequency of planting and the productivity in each of these fields. This research was conducted in June-August 2023 in Tanjung Laut Village, Suak Tapeh District, Banyuasin Regency. The method used in this research is survey method with sampling technique using Simple Random Sampling by taking 216 samples on each land. There were 2 fields used, namely field 1 which was the first time watermelon plants were planted and field 2 which had been planted with watermelon for 3 times (this research was the third time planting). The planting distance used was 0.6 x 4.5 (m). The results of this study are diseases that often attack watermelon plants in this study are anthracnose disease caused by Colletotrichum orbiculare, Cercospora disease caused by Cercospora citrullina, fusarium wilt disease caused by Fusarium sp. and yellow creeping disease. The percentage of anthracnose disease attack in this study was 98.99% in field 1 and in field 2 was 99.06%, which was not significantly different in the T test (P-value 0.93), while the severity of anthracnose disease in field 1 was 46.48% and in field 2 38.99 (P-value 0.0001). Fusarium wilt was the most alarming disease in field 1 at 31.48% and in field 2 at 13.43%. There was an association between the frequency of watermelon planting and the incidence of fusarium wilt disease (P-value 0.00001). Productivity of watermelon plants in field 1 averaged 4.04kg/plant or 14.5 tons/ha while field 2 had a productivity of 5.02/plant or 17.9 tons/ha. The T-test results showed a significant difference between land 1 and land 1 (P-value 0.00003).

Abstract

This research aims to assess the impact of rice husk charcoal application on the growth and yield, as well as to determine the optimal dosage of rice husk charcoal for enhancing the growth and yield of red ginger rhizomes (Zingiber officinale, Rosc.) variety Jahira 1. The experiment was conducted in Ciruluk Village, Kalijati District, Subang Regency, from June to September 2022. The study utilized an experimental method with a randomized block design consisting of four replications and six treatments of rice husk charcoal dosage. The treatments included: P0 = 0 ton/ha, P1 = 2.5 ton/ha, P2 = 5 ton/ha, P3 = 7.5 ton/ha, P4 = 10 ton/ha, and P5 = 12.5 ton/ha. The results of the study indicate that the application of rice husk charcoal significantly affects the growth of red ginger plants (Zingiber officinale, Rosc.) variety Jahira 1. The dosage of 10 ton/ha of rice husk charcoal resulted in the tallest plants at the observation of 4 weeks after planting (WAP), while doses of 5 and 7.5 ton/ha provided the best results at 8 WAP. Treatments P2 (5 ton/ha), P3 (7.5 ton/ha), P4 (10 ton/ha), and P5 (12.5 ton/ha) yielded the best results at 12 WAP. The application of rice husk charcoal also influenced the leaf count, where the dosage of 5 ton/ha (P2) yielded the best results at 4 WAP, while doses of 5 and 7.5 ton/ha (P2 and P3) provided the best results at 8 WAP. The application of 7.5 ton/ha (P3) resulted in the highest number of shoots at 12 WAP. The application of rice husk charcoal did not have a significant effect on leaf length, rhizome weight per plant, and rhizome weight per plot.
