Abstract

This study aims to estimate production factors and technical efficiency of rice farming using the corporate farming model. The research location was determined purposively in Sukoharjo Regency, Central Java. The research sample is 51 corporate farmers determined by census. The analytical method uses the stochastic frontier 4.1.C computational program with the Maximum Likelihood Estimation (MLE) method. The estimation results show that the factors that influence rice production are land area, Urea fertilizer and NPK fertilizer. While the value of the technical efficiency of rice farming in the corporate farming model is 0.75 (75%). Farmers still have the opportunity to increase their efficiency by 25%.

Abstract

The purpose of this study was to obtain information about the good concentration of PGPR for the growth and yield of reciprocal crosses of purple waxy corn and sweet corn (Zea mays L.), the effect of PGPR on the character of a reciprocal cross between purple waxy corn and sweet corn (Zea mays L.) and the effect of reciprocal crosses of purple waxy corn with sweet corn (Zea mays L.) on the character of maize yield. The research was conducted in Tegalgondo Village, Karangploso District, Malang Regency, East Java Province. The study was arranged in a Split-Plot Design consisting of 4 main plots (PGPR Concentration) V0 (Without PGPR), V15 (15 ml PGPR / l water), V30 (30 ml PGPR / l water), V45 ( 45 ml of PGPR/ l of water) and consisted of 4 subplots (crosses) PW (Purple Waxy Maize), PWSC (Purple Waxy Corn♂ x Sweet Corn♀), SC (Sweet Corn) and SCPW (Sweet Corn♂ x Purple Pulut Corn). ). The data obtained were analyzed using the Analysis of Variance (ANOVA) at the 5% level. If there is a significant effect between treatments, it is continued with a comparison test with a 5% LSD test using Costad software and Microsoft Excel. Based on the results, it can be concluded that there is an interaction between the administration of PGPR and the reciprocal cross of purple waxy corn x sweet corn on the observation of sugar content characters. PGPR treatment with PGPR concentration of 45 ml/l water (V45) can increase growth and yield characteristics. The results of the reciprocal crosses (PWSC) of Purple Waxy Maize x Sweet Corn and (SCPW) Sweet Corn x Purple Waxy Maize showed that the female parents were more dominant than the male parents.

Abstract

This study was aimed to determine the genetic variance of several F2 population traits of maize, broad heritability values and phenotypic correlations between yields and other quantitative traits. The method used is the experimental method. The experiment was designed in a randomized block design, with 6 replications. The number of treatments was 4 populations, namely population F2, Sinta Unram, hybrid NK212 and NK7328. Each population was planted in 4 rows, each consisted of 40 plants. The observed characteristics included plant height, leaf number per plant, leaf angle, ear length, ear diameter, weight of dry ear harvested per plant and yield (dry seed weight per plant). The data were analyzed by simple statistical analysis and analysis of variance at the 5 percent level of significance. The results showed that the genetic variance of plant height, leaf angle, and dry cob weight at harvest per plant population of F2 was higher than that of Sinta Unram's genetic diversity with relatively wide genetic diversity. The genetic variance of leaf number per plant, ear length and ear diameter were also higher than that of Sinta Unram; but the genetic diversity is quite narrow. The genetic diversity of the F2 population's traits is the same as that of Sinta Unram with a broad category. The heritability value of broad meaning classified as high (> 50 %) was obtained on plant height, leave number per plant, ear length, ear diameter, weight of dry ear harvested per plant and yield; while the leaf angle is classified as moderate. Harvested dry cobs weight per plant showed strong phenotypic correlation with yield (0.827); while other properties are classified as very weak to moderate. Improving the yield of the F2 population can be done by indirect mass selection using the weight of harvested dry cobs per plant as the selected trait

Abstract

Peat soil has the potential and is widely available to be used for shallot cultivation with good and proper management, peat land is classified as marginal land for various types of plants because the soil condition is saturated with water, reacts acidic and contains toxic organic acids and low nutrient status so the condition of plant root media that is not conducive to root development so that it becomes a limiting factor in shallot cultivation. Efforts to increase peatland productivity for shallot cultivation can be carried out by adding organic fertilizers and using rhizosphere microorganisms such as Abuscular Mycorrhizal  Fungi (AMF), this study aims to get a dose of organic fertilizer and AMF which can increase shallot production on peat soil. The research method used a separate experimental design (Split Plot) Completely Randomized Design  which consisted of 2 factors, namely: AMF treatment (M) main plot consisting of 2 levels (without AMF application and AMF application), the second factor was the dose of organic fertilizer (O) child plot consisting of 6 levels (0 tons ha-1 , 3 tons ha-1, 6 tons ha-1, 9 tons ha-1, 12 tons ha-1 and 15 tons ha-1) there were 12 treatments each repeated 3 times, which was carried out in January-April 2021 in Pontianak City with the parameters of observing plant height, number of leaves, number of tillers, harvested dry tuber weight, harvested dry plant weight and tuber diameter. and the number of leaves, while the AMF treatment independently had a significant effect on the observation of the number of tillers, the weight of harvested dry tubers, the weight of harvested dry plants and the treatment of organic fertilizer with a dose of 3 tons h-1 showed good results because they were not significantly different from the required mines 15, 12 and 6 tons ha-1 .

Abstract

Research on the response to NPK 12-6-27 fertilization on oil palm seedlings was carried out on Oxisols acid dry soil from Bogor. Oil palm seedlings were planted in pots at the age of 3 months after the prenursery phase and maintained for 6 months. The purpose of the study was to determine the response of the NPK 12-6-27 fertilizer formula to the growth of oil palm plants in the main nursery and to obtain information on the optimum dose. The experimental design used was a randomized block with 7 treatments which were repeated 8 times. The treatments consisted of control, standard NPK, and five doses of NPK fertilizer formula 12-6-27. The results showed that the soil has a low level of soil fertility. Soil fertility constraints include acid soil pH (pH-H2O = 4.7), level of C and N, P and K, cation exchange and cation exchange capacity (CEC) were low and high level of Al saturation (54%). At 6 months after application (BSA) fertilizers, application of NPK significantly increased oil palm plant height. The plant height in the Control treatment was about 71.4 cm and increased to 86.0 – 93.4 cm in the standard NPK and NPK 12-6-27 treatments. The standard NPK and NPK 12-6-27 treatments did not produce significantly different plant heights. The Control treatment resulted in stem dry weight of 114.3 g/pot and significantly increased to 158.2 – 207.0 g/pot with standard NPK and NPK 12-6-27. Fertilization of NPK 12-6-27 doses of 1.5 x and 2x resulted in plant dry weight of 206.3 g/pot and 207.0 g/pot higher and significantly different than standard NPK which resulted in plant dry weight of 158.2 g/pot. The RAE value of NPK 12-6-27 fertilizer is 120 – 211 higher than the standard NPK namely 100. The optimum dose of NPK 12-6-27 is 51 g/pot given for 6 months in the main nursery

Abstract

Shallot cultivation is usually carried out on land with a lack of sunlight, so that the selection of shade-adaptive shallot genotypes is very important. This study aimed to know yield potential and tolerance level of  varieties of shallots in sunlight deficit. This study was arranged using a Completely Randomized-Split Plot Design with five replications. The genotypes used were Keta Monca, Lokananta, Bali Karet, Ampenan, Thailan Nganjuka and Super Philip. The sunlight deficit was carried out using a black paranet with 65% sunlight barrier. The experiment results showed that shallot varieties have different yields potential against sunlight deficit stress. Shallot crop under sunlight deficit stress caused a reduction in bulb wet weight, bulb dry weight, leaf wet weight, number of bulbs, root dry weight, and leaf dry weight. The Lokananta variety produced the heaviest wet weight of bulb per clump (33.7 g per clump) with a decrease in bulb wet weight only 4.8% under sunlight deficit conditions, and the sensitivity index value was moderate tolerant to sunlight deficit

Abstract

Sub-districts Kie and Fatumnasi are two sub-districts in mainland West Timor that cultivate local potatoes from Soe. This germplasm needs to be preserved and developed to diversify non-rice alternative food. One of the main obstacles in cultivating potatoes is the presence of pests, but so far there have been no reports of pests on local potato plants from Soe from the two sub-districts, so this research needs to be done. This study aimed at an inventory of important pests on local potato plants from Soe as a database for early detection to prevent the occurrence of explosive pests. This research was conducted on potato plantations in Fatuulan Village, Ayofanu Village, Nunleu Village, and Nenas Village. The method used is a purpose survey at a specified sample point. A sampling of insect pests is done by direct observation and insect nets. The pests found were put in a killing bottle or 70% alcohol, collected, and identified. Observation variables include the type of pest, symptoms of pest attack, and morphological characteristics of the stadia found. The data obtained were analyzed descriptively. The results showed that five species of pests damaged local potatoes from Soe. The five pests were Spodoptera litura, Henosepilachna vigintioctomaculata, Liriomyza sp, Phthorimaea operculella, and Nezara viridula. The identification results showed that in Kie District there were three pest species, namely S. litura, H. vigintioctomaculata, and Liriomyza sp. Meanwhile, in Fatumnasi District, there were four types of pests, namely H. vigintioctomaculata, Liriomyza sp, P. operculella, and N. viridula
