Abstract

Conservation agriculture (CA) is a sustainable farming system that can confer agronomic, ecological, and economic benefits to farmers across the globe. This study evaluated the effects of different cropping systems on soil properties, crop and fodder yields, and economic returns. Data was collected from a four-year-old experiment at Chinhoyi University of Technology farm with seven treatments [no-till (NT), NT + dead mulch (DM), NT + live mulch using Brachiaria and Desmodium uncinatum (LM), NT + rotation (ROT), NT + DM + ROT, NT + LM + ROT and conventional tillage (CT)] in a randomized complete block design with three replications. Compared to CT, NT + LM + ROT reduced soil bulk density by 5.6% and increased water-holding capacity by 49.8%. Soil organic matter was lowest in CT (1.8%), and highest in NT + DM + ROT (5.5%). CT also resulted in lower soil pH (5.6) than NT-based systems (pH = 6.4-7.2). While NT + LM + ROT improved bulk density and water-holding capacity, NT + DM + ROT enhanced soil organic matter. NT + DM increased maize and soybean yields by 31.8% compared to CT, whereas NT and NT + LM reduced yields by 58.5-91.3%. Despite these yield differences, NT systems with DM or LM exhibited 37.4% lower total variable costs and greater economic performance than both CT and NT. These findings demonstrate the potential of CA to improve soil health, enhance financial returns, and boost yield, offering a sustainable alternative for agricultural production.

Abstract

Proper management of nitrogen (N) and potassium (K) is needed to increase maize productivity in the area having low soil fertility due to their crucial role for plant growth and production. The research aimed to analyze the effect of N and K fertilizer doses on growth, production, radiation use and agronomic efficiencies during two years maize cultivation. The research was carried out on March to July 2021 and January to May 2022 in Jatikerto Agro Techno Park, Malang - East Java, Indonesia. The experiment used 16 treatment combinations of nitrogen (0, 38, 77, and 115 kg N/ha in 2021 and 0, 50, 100, 150 kg N ha-1 in 2022) and potassium (0, 33, 67, and 100 kg K ha-1 in 2021 and 0, 50, 100, and 150 kg K ha-1 in 2022) fertilizer rates, and repeated three times of each. Maize growth and production (such as plant height, leaf number, leaf area index, interception photosynthetically active radiation, radiation use efficiency, yield) were significantly increased by application 77 and 150 kg N ha-1 combined with 67 and 150 kg K ha-1. The study found strongly effect of leaf area index and radiation use efficiency in increasing grain yield of maize (R2 = 0.94 and 0.98, respectively). However, the increases fertilizer rates should be anticipated their negative effect on agronomic efficiency. Therefore, proper combination of N and K should be considered to obtain the optimum maize growth and production, as well as maintain radiation use and agronomic efficiencies.

Abstract

Eggplant (Solanum melongena L.) is a type of fruit vegetable that is liked by many people and has an ever-increasing demand. Productivity needs to be increased starting from technical improvements in eggplant cultivation to post-harvest treatment. One of the things that need to be considered in cultivating is the availability of sufficient nutrients to support the growth and yield of eggplant plants. The addition of nutrients can be done by fertilizing. The fertilizers given consist of two types, namely organic fertilizers and inorganic fertilizers. This study aims to study and analyze the effect of the right dose of a combination of NPK fertilizer and chicken manure on the growth and yield of eggplant plants. This research was carried out from November 2020 to February 2021 in Situbondo City. This study used a randomized block design (RBD) with 10 treatments and was repeated 3 times. The dose of chicken fertilizer consisted of 5, 10 and 15 tons ha-1, the dose of NPK fertilizer consisted of 200, 300 and 400 kg ha-1. The results showed that the addition of chicken manure and NPK fertilizer had a significant effect on eggplant growth and yield. The treatment of 300 kg ha-1 NPK + 5 tons ha-1 chicken manure had a significant effect on plant height and fruit weight per plant, while 200 kg ha-1 NPK + 15 tons ha-1 chicken manure had a significant effect on the number of leaves, area leaves, number of flowers, fruit length, and fruit diameter.

Abstract

Cassava (Manihot esculenta) cultivation is often carried out with an intercropping pattern with upland rice (Oryza sativa L.) as an intercrop which is expected to increase production and maximize land use. Cassava and upland rice have the same land characteristics, which are planted on dry land so they are suitable for intercropping. The effort used to make land efficient in this system is to adjust the planting time between intercropping plants and the main crop. The purpose of this study was to determine the effect of planting time of upland rice (Oryza sativa L.) on cassava (Manihot esculenta) intercropping. This research was carried out from May to September 2021 in front of Universitas Brawijaya at Mrican Village, Mojoroto District, Kediri City with a place height of 67-100 meters. The study was conducted using a one factor Randomized Block Design (RBD), which is planting time with a combination of 5 treatments and replications. The treatments used included W1: upland rice planting time 14 days before cassava, W2: upland rice planting time 7 days before cassava, W3: upland rice and cassava planted together, W4: upland rice planting time 7 days after cassava , W5 : planting time of upland rice 14 days after cassava. Data were analyzed using variance (ANOVA), if there was a significant effect it was continued with a follow-up test of Honest Significant Difference (BNJ) at 5% significance level. The most appropriate treatment is planting time for upland rice 14 days after cassava, due to the low competition between cassava and upland rice so that cassava and upland rice yields will remain good.

Abstract

White oyster mushroom (Pleurotus ostreatus) is a type of popular mushroom in Indonesia. Some market demands require a wide cap size because it can add to the aesthetic value of the product and consumer satisfaction in consuming white oyster mushroom chips, especially the mushroom cap. This increased demand is not matched by high productivity so that farmers cannot meet market demand. This study aims to determine best treatment combination between amount of baglog tearing and paranet layer, to optimize oxygen levels by providing suitable humidity conditions for paranet layer, and to test the effectiveness of baglog tearing treatment, by giving paranet layer with proper tearing effectiveness is expected to increase the diameter of fruit cap and total fresh weight of mushrooms. This research was conducted at Kumbung Griya Jamur, Agriculture Faculty, Brawijaya University, Pucangsongo Village, Tumpang District, Malang Regency, East Java in January - April 2019. Method of this research used was a  Split Plot Design also the data were tested using ANOVA and 5% BNJ real test. The results of this study indicated that the best fruit cap diameter was produced in 2-layers paranet with the treatment of 1- layer tearing of 9.33 cm, which increased the fruit cap diameter by up to 86% compared to the 3-layer paranet treatment without tearing. The best total fresh weight was obtained from 2-layer paranet with a value of 877.2 g, which increased the total fresh weight by up to 19% when compared to the 1-layer paranet and 2-layer paranet treatment.
