Analysis of The Equivalent Land Use (ELU) in the Milpa System Intercalated with Fruit Trees (MIAF) in Axochio, Veracruz

/0 Comments/in /by

The Intercropped Maize and Fruit Tree System (MIAF) represents an agroecological alternative aimed at improving the productivity, sustainability, and resilience of tropical agroecosystems in the face of the limitations of traditional monocultures. In this context, Land Use Equivalent (LUE) is a fundamental indicator for evaluating the productive efficiency of diversified systems. The objective of this research was to evaluate the Land Use Equivalent in the MIAF system established in Axochio, Veracruz, in order to determine its efficiency compared to monocultures. The research was conducted during the years 2024, 2025, and 2026 at the MIAF-INIFAP Module in Axochio, San Andrés Tuxtla, Veracruz. The evaluated system consisted of 16 species, including fruit trees and annual crops. To determine the LUE, the yields obtained in association within the MIAF system and the national yields for monoculture reported by SIAP and SIACON were used. The results showed high productive diversity, highlighting species such as sapodilla, Persian lime, starfruit, and maize. The total land use efficiency (LUE) obtained was 4.83, a value greater than one, indicating that the integrated agroforestry system (MIAF) uses land more efficiently than monocultures. The largest contributions to the UET came from maize and starfruit. It is concluded that the MIAF system promotes ecological complementarity among species, optimizes resource use, and constitutes a viable strategy for strengthening sustainability and food security in tropical regions.

The purpose of cultivation intensity and using kind Urea mature as an activity in corn culture creates the best environmental to plant growth and yield. The experiment was conducted in Sempaja village-Samarinda district. Randomized Split-Plot Design analysis in Randomized Block Design was used with 2 treatments and 3 replications. The treatments consist of two method of tillage (no tillage and conventional tillage) and two kind of urea mature (without Urea, Prill Urea and Briket Urea). The result showed that combination with conventional tillage method and briket urea give significantly effect on plant growth, yield components, and yield of corn.

Nitrogen and Chicken Manure Effect on Corn Growth and Yield in Double Row Cropping Patterns

/in /by

Corn (Zea mays L.) is a common food and feed product in the community since it is commonly used as rice substitution as food staple. Fertilizer application is required to attain crop high yields. Plants can receive nutrients from synthetic nitrogen fertilizers (NF) during their growth cycle. However, excessive use of NF might harm the environment. Organic chicken manure (CM), on the other hand, can minimize the harmful impact of NF. Chicken manure benefits to improve the soil’s physical, chemical, and biological properties. To boost maize plant growth and productivity, might employ CM and NF. The objective of this study was to determine the effect of NF and CM on corn growth and yield. This research was conducted in Kembang Seri, Central Bengkulu, Indonesia from November 2019 to February 2020 using Randomized Complete Block Design (RCBD) with two factors and three replications. The first factor was NF doses (100, 125, and 150 %), and the second-factor consisted of CM doses (0, 10, and 20 tons/ha). Data were analyzed using ANOVA F-5%. On shoot dry weight of corn cultivated in a double row cropping pattern, there was an interaction between the dose of N and chicken manure. At 0 tons/ha, the optimum N fertilizer dose for chicken manure is 135.96 %, or 407.86 kg urea/ha. At a dose of 20 tons/ha, the optimum N fertilizer dose for chicken manure is 141.22 %, or 423.65 kg urea/ha. In a double row cropping pattern, different nitrogen fertilizer doses had no effect on corn growth and yield. The optimal dose of chicken manure was 16.65 tons/ha for plant height, 17.35 tons/ha for stem diameter, 18.89 tons/ha for leaf greenness, 17.35 tons/ha for cob length, 15.01 tons/ha for cob weight, 18.87 tons/ha for dry seed weight/plant, and 19.74 tons/ha for dry seed weight/plot.
