Abstract

The simultaneous use of additive main and multiplicative interaction effects (AMMI) and best linear unbiased predictors (BLUP) has been reflected in the multi-location evaluation of trials for number of crops. The additional advantages of both these approaches would be combined in superiority index (SI) to have an edge over the commonly used approaches. The promising wheat genotypes had been considered under multi location trails in Peninsular zone of India during the cropping seasons of 2018-2019 and 2019-2020. The highly significant environmental effects contributed 44.1% & 35.3% of total sum of squares in the AMMI analysis, 20.6% & 26.2% were augmented by G × E interaction, while 10.8% & 7.5% were contributed by the genotypes.Wheat genotypes of UAS3001, MACS6222, GW322, and DDW48 expressed their superiority in BLUP values. Superiority indexes and adaptability measures had identified WHD964 and DDW48 genotypes for the second year of study. More than 75% variations among the considered measures were due to the first two interaction principal components (IPCA’s) under Biplot analysis. Number of superiority index measures were clustered with adaptability measures in the same quadrant. Superiority index, the weighted measure of yield and consistent performance of genotypes would be more appropriate for stability and adaptabilities studies.

Abstract

Continuous climate change increases the number of droughts in some areas, thereby affecting agricultural production. Cultivation of coix millet (Jali plant in Indonesian) is profitable because of its high adaptability to drought stress, and its seeds have the potential to be used as food due to their benefits for body health. The application of organic matter, namely husk charcoal, was chosen to increase agricultural production under drought stress. Therefore, this study aimed to determine the effects of husk charcoal on the biochemical and physiological properties of coix millet during vegetative phase under drought stress and to determine the longest watering interval the plant can tolerate. Research was arranged in a split-plot design with three replications. The main plot consisted of three watering intervals (every two, four, and six days). The sub-plots consisted of three doses of husk charcoal, namely 0 g polybag⁻¹ (0 tons ha⁻¹), 32 g polybag⁻¹ (10 tons ha⁻¹), and 64 g polybag⁻¹ (20 tons ha⁻¹). The data were analyzed using analysis of variance (ANOVA) and tested using Duncan's Multiple Distance Test (DMRT) at a significant level of 5%. The results showed that husk charcoal could increase the chlorophyll content in plants experiencing drought stress. The longest watering interval that could be tolerated by coix millet given husk charcoal at the optimal dose (64 g polybag⁻¹) was once every four days.

Abstract

An ameliorant is a chemical that can be used to improve soil fertility. The improving agents include dolomite and steel slag. Steel slag is a by-product of the steel industry containing CaCO3, SiO2, CaSiO3, and MgO, which can be used to improve the growth and yield of rice plants. Dolomite, on the other hand, is a limestone rock containing MgO and CaO, which is useful in agricultural soils. This study aimed to determine the types and doses of ameliorants affecting the growth and yield of rice plants (Oryza sativa L.). The research was carried out at Sukadana Village, Ciomas Serang-Banten District. A non-factorial Group Randomized Design with seven treatments was employed in this investigation. The treatments include P0 = No treatment (control), P1 = 2 t/ha of dolomite, P2 = 2 t/ha of dolomite + 2.5 t/ha of steel slag, P3 = 1.5 t/ha of steel slag, P4 = 2.5 t/ha of steel slag, P5 = 5 t/ha of steel slag, and P6 = 7.5 t/ha of steel slag. Observation was made on steel slag characterization, plant height, the total number of tillers, the weight of 1000 grains, the amount of grain per clump, and the weight of dry-milled grain. The results showed that applying dolomite at 2 t/ha and steel slag at 2.5 t/ha could increase the weight of 1000 grains of rice, and applying steel slag at 1.5 t/ha could enhance the amount of grain per clump.

Abstract

Basil is a plant that can be cultivated in Psamment (coastal sandy soil). Basil requires nitrogen (N) and sulfur (S), so the N-S balance is needed to obtain optimal results. Psamment contains low colloid, causing nutrients to be barely bound and easily lost. Zeolite and biochar can be a solution. This study aimed to determine the composition and frequency of fertilization, as well as the use of soil amendment for basil growth. This research consisted of two interrelated studies arranged in a Randomized Complete Block Design. The research was conducted in Bugel, Panjatan, Kulon Progo, and the analysis was performed at the Soil Department Laboratory, Faculty of Agriculture, Universitas Gadjah Mada. The first study consisted of two factors, namely Urea-ZA composition (0:0, 60:40, 70:30, 80:20, 90:10, and 100:0) and frequency of fertilization (every 1 and 2 weeks). The application of Urea-ZA (80:20) gave the best fresh-dry weight, N-S content, and N-S uptake of basil, and this result was used as the reference for the second study. The second study consisted of two factors, namely Urea-ZA fertilizer doses (50%, 75%, and 100%), and types and doses of soil amendment (without amendment, zeolite 7.5 t/ha, zeolite 15 t/ha; biochar 7.5 t/ha, and biochar 15 t/ha). It can be concluded that soil amendments application improved the chemical properties of psamment, fresh-dry weight, N-S content, and N-S uptake of basil. Furthermore, biochar and zeolite could increase the effectiveness of fertilization, so the dose of Urea-ZA fertilizer could be reduced until 50%.

Abstract

Crown flower (Calotropis gigantea (L.)) is a weed plant potentially to be used as raw material for textile fibers yet the utilization is not optimal. Efforts to optimize the utilization of C. gigantea are needed. This research aimed to determine the appropriate concentration of plant growth regulators, including NAA (Naphthalene Acetic Acid) and BA (Benzyl Adenine) to stimulate optimal growth of C. gigantea to be used as the basis for in vitro propagation of C. gigantea. The research was arranged in a completely randomized design (CRD). Explants were planted on Murashige and Skoog (MS) medium with various concentrations of NAA (0; 0.5; 1; 1.5; and 2 ppm) and BA (0; 1; 2; 3; and 4 ppm). Based on the research result, the addition of 3 ppm BA followed by increasing the concentration of NAA to 1.5 ppm could increase the number of C. gigantea shoots, and giving 1 ppm BA followed by adding 1.5 to 2 ppm NAA increased shoot height. The best plantlet response was found in media with 0 ppm NAA and 4 ppm BA, which could produce an optimal shoot height of 5.9 cm and a large number of shoots of 5.67 shoots. Increasing NAA concentration retarded root formation and reduced the root length and number of leaves, while the medium without NAA gave the earliest root emergence of 11 days after planting, the number of leaves of 20 strands, and the longest root of 10.9 cm. Applying a single substance BA did not accelerate all the variables observed.

Abstract

Soil health indicators are related to environmental factors, such as nutrient management, crop practices, different cropping systems, and biodiversity. 14 soil health indicators were measured and compared in our study to clarify the impact of different cropping system on soil quality. The primary comparisons were carried out among perennial plants, annual plants, and cover cropping, with an examination of the tillage system and fertilization taken into account during the analysis. Multivariant analysis recorded that the most promising indicators of soil health that related to soil quality and health were organic carbon (OC), total carbon (TC), followed by fall soil total nitrogen (TN). The main factor for clustering treatments based on indicators was N fertilization according to Euclidean distance that was applied to measure similarity of the groups. Although perennials and cover crops recorded more carbon sequestration and TC improvement, corn crops showed the worse impact on soil pH and bulk density (BD). Non-tillage practices significantly increased wet aggregate and soil moisture. The combination of TC field measurements with long-term cropping systems information has improved our understanding of how different cropping practices influence SOC improvement in soil full profile. It would develop appropriate and cost-effective agricultural management activities, maintain or improve carbon soil accumulation to guide farmer decision making, and ultimately advance food and nutritional security.

Abstract

This research aimed to determine the effects of various soil tillage techniques and the use of organic and chemical fertilizers on the overall yield and quality of fava beans. The study emphasized the significance of fertilizer types and their interaction with soil tillage methods. Although the quantity of grains per pod was notably influenced by the choice of fertilizers, the impact of soil tillage alone was found to be insignificant. Moreover, this study demonstrated that the yield index of fava beans was significantly influenced by fertilizer sources, emphasizing the importance of proper nitrogen managements. These findings provide valuable insights for enhancing crop production and quality through optimized soil tillage practices and the use of organic and chemical fertilizers. Through an examination of both the measurable and qualitative elements of fava bean cultivation, this study offers valuable knowledge on how to optimize the application of nitrogen fertilizers and effectively utilize mycorrhizal inoculation to improve grain yield and seed quality. These findings have implications for sustainable agriculture practices and guide farmers and researchers in making informed decisions regarding soil management strategies in fava bean cultivation.
