Abstract

This study aims to determine the effect of leaf fertilizer on three nutrient efficient corn genotypes in tidal land. This research was coducted  in Village Mulia sari, Sub-district Tanjung Lago, District Banyuasin, South Sumatra in the noble village of Sari Tanjung Lago sub-district from August to December 2017. This study uses the Split Plot Design consisting of 3 factors, namely the first factor of genotype, the second factor is the dose of urea A0 = 0 kg, A1 = 250 kg, A2 = 300 kg and the third factor of leaf fertilizer consists of: P0 = (control without spraying), P1 = 30 days of spray, P2 = 45 days of spray, P3 = 30 + 45 days of spray, P4 = 60 days of spray, P5 = 75 days of spray, P6 = 60 + 75 days of spray. repeated three times. Observation results used of 300 kg of urea fertilizer and leaf fertilizer had a good influence on the growth of G3 corn genotypes and the production of corn plants in tidal land. The combination of giving 300 kg of urea fertilizer + leaf fertilizer gives a pretty good influence on the growth of G3 corn genotypes with a production of 7.44 Ton/hectares

Abstract

The Indonesian Government's efforts to enhance Human Resource (HR) quality include ensuring adequate food production, purchasing power, access, and nutritional intake. This study aims to assess the impact of single and mixed herbicides on corn plant growth and yield. Employing a Randomized Block Design (RBD) with eight treatments replicated three times, the research was conducted from February to June 2023 at the Farmer's Gar-den. Results indicated that herbicide treatments, particularly those with atrazine + saflufenacil as the active in-gredients, demonstrated the most favorable effects on plant height at 6 WAP and 8 WAP, the number of leaves at 6 WAP, ear length, ear weight, and dry seed weight per plot. The atrazine + saflufenacil herbicide treatment had the best effect on plant height at 6 WAP and 8 WAP, number of leaves at 6 WAP, ear length, ear weight, and dry seed weight per plot.

Abstract

Stenochlaena palustris, commonly known as pakisan weed, poses significant challenges in oil palm plantations due to its highly invasive nature, which can lead to reduced agricultural productivity. Management of this weed is critical, as effective control measures can inhibit its dominance and promote the proliferation of alternative weed species, thereby enhancing biodiversity within the ecosystem. This study aimed to 1) assess the effectiveness of the herbicide ammonium glufosinate, in combination with an adjuvant, for controlling S. palustris in oil palm plantations, and 2) investigate the subsequent alterations in the weed community structure following herbicide application. We employed a randomised group design (RAK), incorporating the herbicide with added adjuvants. Results showed a clear change from S. palustris to Asystasia sp. as the dominant species. Treatments K and H had the most Asystasia sp., while treatment L had the least. Furthermore, we clearly compared treatments L, K, and S to the control treatment, emphasizing the emergence of diverse species within the treatment plots. However, low levels of diversity and evenness suggest a stressed weed community, indicating that the herbicide application can disrupt existing ecological balances. This study emphasizes the importance of assessing herbicide impacts not only on targeted weed species but also on broader community dynamics, revealing a significant research gap in understanding the long-term ecological consequences of herbicide use in oil palm plantations.
