Abstract

This Crystal Guava was introduced in Indonesia in 1991 by the Taiwan Technical Mission. Various attempts have been made to achieve maximum productivity results, but these efforts have not been fully successful due to constraints such as pest attacks. Pests that attack crystal guava fruit are fruit fly pests. Fruit fly pests are pests that damage plants, especially types of horticultural crops, especially fruit and vegetable plants. Fruit fly attacks in Indonesia reach 50% and when the fruit fly population is high, the attack intensity can reach 100%. The purpose of this study was to find out the types of plant extracts that are effective and effective in attracting fruit flies in pest control, to find out the optimal concentrations to attract fruit flies in pest control in guava crystals and to find out the best time to apply extracts to attract flies. fruit in pest control on crystal guava plants. The data obtained from this study were presented in a factorial randomized block design (RBD) with 3 factors. This study consisted of 27 treatment combinations and 1 control with 3 repetitions and each treatment in one repetition there were 5 samples. Observational data were analyzed using Analysis of Variance (ANOVA) and interpretation of the data was carried out by further testing using the Honest Significant Difference (HSD) test at 5% level and orthogonal contrast test.

Abstract

The aim of this study was to obtain information about plant characteristics from the result of M4 generation from MSP13 rice mutants which has the potential to have higher production yields and early maturity than non-mutant rice, Ciherang and Inpari 32. The research was conducted from April to August 2022. The location of this research was done in the Pendem area of Campus III, University of Muhammadiyah Malang, Tegalgondo village, Karangploso, Malang. The result of the research on the characteristic of M4 generation rice mutants (Oryza sativa L.) which has the potential to have higher production yields and early maturity indicated that M4 mutant rice plants aged 98.00 days on average is very early maturing, non-mutant is in the early maturing category with an average harvest age of 97.66 days, meanwhile Ciherang is in the early maturing category with an average harvest age of 99.33 days and Inpari 32 has an average of 99.33 days so it is included in the early maturing category. Rice age at flowering, plant height, rice age at harvest, number of productive tillers, panicle length, number of grains in each panicle, weight of 100 grains of M4 mutant rice plants differed with each comparison variation. Cluster analysis results for each variety with the variables age of rice at flowering, plant height, age of rice at harvest, number of productive tillers, length of panicles, total number of grain per panicle, total grain weight per panicle, number of full grain per panicle, grain weight fruitful per panicle, and 100 grain weight consisting of 2 groups. The first group has a similarity level of 30,80% while the second group has a similarity level of 30,77% with a kinship of K1 and K2 of 0.00%.

Abstract

Watermelon (Citrullus lanatus) is a widely consumed and cultivated fruit in Indonesia, cherished for its numerous benefits, high economic value, and short plant life. To enhance watermelon quality, plant breeding is employed, aiming to develop superior hybrid varieties. This study, conducted between September and November 2022 on PT. Aditya Sentana Agro's experimental land, evaluated candidate hybrid watermelon varieties (codes 3078, 3079, 3080, 2844, 2845) against comparison varieties (Winda, Mardi, Black Panther, Palguna). Using Randomized Complete Block Design (RCBD) with one genetic factor at 9 levels, repeated 3 times, a total of 27 experimental units were established, each consisting of 10 plants, summing up to 270 plants. Qualitative variables such as fruit skin color, pattern color, flesh color, and shape, along with quantitative variables like fruit weight, length, diameter, dissolved solids, flowering day, skin thickness, and percentage of fruit damage, were observed. The research revealed variations in fruit weight, length, diameter, dissolved solids, and flowering day among the different varieties. Promising candidates for new varieties were identified as codes 2845 and 3078 based on these quantitative traits. This study contributes valuable insights into the potential advancements in watermelon breeding, emphasizing the importance of selecting varieties with desirable characteristics for improved agricultural outcomes.

Abstract

The ridge gourd plant (Luffa acutangula L.), native to India, thrives in Southeast Asian countries, including Indonesia, and holds significant value in traditional medicine. This study, conducted from September to December 2022 on PT Aditya Sentana Agro's experimental land, aimed to identify superior genotypes with high yield potential for ridge gourd production. Employing a Completely Randomized Group Design with one factor (genotype) and three replications, the research focused on qualitative (e.g., stem and leaf characteristics, flower and fruit attributes) and quantitative variables (e.g., leaf width, stem dimensions, flowering and harvest age, fruit dimensions, weight, yield, and storability). Notable findings include variations in fruit skin color as a qualitative trait. In terms of quantitative traits, certain variables such as leaf width, male flowering age, harvest age, fruit diameter, fruit length, and weight per fruit did not exhibit significant differences among genotypes. To enhance ridge gourd production, the study suggests the development of varieties with high yields and early maturation. This could contribute to the plant's adaptability in both highland and lowland environments. The comprehensive evaluation of qualitative and quantitative traits provides valuable insights for selecting the best candidate varieties to improve ridge gourd cultivation and productivity.

Abstract

The The bambara groundnut has the potential to continue to be developed, but the obstacle faced is the very limited availability of bambara groundnut seeds. This is because there are no varieties from the results of breeding that are released and the low quality of the seeds. Low seed quality is caused by slow germination and results in the seed growth process being non-unison, this is influenced by seed dormancy. The purpose of this study was to determine the effect of soaking time in KNO3 on germination, vegetative morphology, and crop yield in the field by measuring seed viability and vigor, vegetative morphology and yield. The research was carried out for 4 months, from June-October 2022 which took place at the Agrotechnology Laboratory of the Muhammadiyah University of Malang and Dadaprejo Land, Batu City. The study was conducted using a simple Completely Randomized Block Design (RKLT) consisting of 10 treatments, and was repeated 3 times. The observed variables included moisture content, DB, PTM, IV, KCT, T50, plant height, number of leaves, leaf shape, leaf color, stem color, pod color, pod shape, number of pods, pod dry weight, number of seeds, dry weight seeds, yield potential, and weight of 1000 seeds. The results showed that the long soaking of seeds in KNO3 did not affect their vegetative morphology. Soaking time of seeds in KNO3 had no significant effect on DB and PTM values, but had a very significant effect on IV values, the number of leaves in the vegetative and generative phases. And it has a significant effect on the height of the KCT, T50, and plant height in the vegetative phase. As for the yield variable, the results showed no significant effect. Soaking time in KNO3 only affected germination, plant height, and number of bambara groundnut leaves.
