The Effect of Several Rhizobacteria Consortia Formulation and Bacterial Density to the Growth and Yield of Five Maize Cultivars in Indonesia
No full textMaize is one of the important crop so production improvement is must be done to sufficient the needs. Plant growth promoting rhizobacteria has become a feasible, efficient and sustainable approach to increase maize productivity. This study investigated the effect of several rhizobacteria consortia formulations and bacterial density on the growth and yield of five maize cultivars in Indonesia. The experiment was carried out using a nested-split plot randomized complete block design (RCBD). The treatments consisted of two rhizobacteria consortia formulation (granule and liquid) as nested, four rhizobacterial density (0, 107, 108, and 109 cfu mL–1) as main plot, and five maize cultivars (Bisi 18, Bisi 2, Pertiwi 3, Bisi 228, and Bisi 220) as subplot. The growth and yield data were analyzed through ANOVA and by means using DMRT α 5 % to determine the best treatment. Application of rhizobacteria consortia formulation on five maize varieties did significantly affect the growth and yield of maize although bacterial density did not showed the same results. Rhizobacteria consortia with granule formulation appeared significantly higher yield performance than liquid. Pertiwi 3 tended to produce higher average yield than other varieties for both rhizobacteria consortia formulation although the varieties did not significantly contribute on ear weight variables
The interplay between pronunciation self-efficacy sources and self-efficacy beliefs: A structural equation modeling approach
No full textThis study was conducted to find the association between pronunciation self-efficacy sources and pronunciation self-efficacy beliefs. It was quantitative in nature using a correlational research design. A sample of 155 Malaysian ESL university students was selected from two Malaysian universities by employing proportionate stratified random sampling. Two questionnaires were used to collect the data related to pronunciation self-efficacy sources and self-efficacy beliefs. In order to analyze the collected data, the correlational analysis was carried out with a statistical software named Smart PLS 3.0. Findings indicated that all the self-efficacy sources were significantly and positively correlated with pronunciation self-efficacy beliefs, except physiological state, which was significantly but negatively correlated with pronunciation self-efficacy beliefs. Based on the outcomes of this study, implications for ESL instructors and educational policymakers were presented
Effect of Sowing Dates and Seed Rates on the Agro-Physiological Traits of Wheat
No full textWheat yield in Pakistan is very low due to improper seed rate and not sowing the crop at proper time. Delay in sowing of wheat causes linear reduction in grain yield. To evaluate the effect of seed rates and sowing dates on agro-physiological traits of wheat an experiment was conducted at New Developmental Farm, The University of Agriculture Peshawar-Pakistan during winter 2012-13. Randomized complete block design (RCBD) with split plot arrangement having three replications was used. Sowing dates (29th October, 10th November, 24th November, 10th December, 26th December and 10th January) were kept in the main plots, whereas, seed rates (120,150,180 kg ha-1) were allotted to sub plots. Wheat variety “SIRAN-2010” was sown in a plot size of 5m x 1.8m (9 m2), having six rows with row to row distance of 30 cm and row length 5m. All the standard agronomic practices were uniformly adopted for the whole experiment. Results showed that maximum spikes m-2 (411), grains spike-1 (52), thousand grains weight (43 g), biological yield (12327 kg ha-1) and grain yield (5587 kg ha-1) were recorded in plots sown at 10th November. Seed rate of 150 kg ha-1 showed maximum number of grains spike-1 (44), spikes m-2 (307), thousand grains weight (37g), biological yield (9568 kg ha-1) and grain yield (4296 kg ha-1). It was concluded from the results that wheat should preferably be sown between 29th October and 24th November at 150 kg ha-1 seed rate to get higher grain yield in Peshawar valley
Morphological Characterization of Bitter Plant
No full textBitter melon (Momordica charantia L.) is a type of vegetable plant that has a variety of fruit surface patterns, commonly known as wax melts. The melt resembles fine bumps on the surface of the fruit that run along the length of the fruit. The aim of the research was to determine the unique and superior morphological characteristics of bitter melon fruit from 10 candidate varieties compared with six comparison varieties in terms of qualitative and quantitative properties. The research was conducted from October to December 2023 at an experimental field owned by PT. Aditya Sentana Agro. This research uses a descriptive observation method with qualitative and quantitative observations; the results of the observations are in the form of data displayed in tables. The variables observed include qualitative and quantitative variables; qualitative variables include fruit color, fruit shape, wax melt shape, stem color, and quantitative variables include fruit length, fruit diameter, weight per fruit, number of fruits per plant, and total fruit weight/plant. The results of the study showed that of the 10 candidate varieties, there were three candidate varieties that had advantages and uniqueness in both qualitative and quantitative properties
