Abstract

         The aim is to know the potential of chilli production in sub obtimal soil and to know the effect of organic and inorganic fertilizers on the growth and production of chilli plants. The method used in this study was in the form of a field experiment arranged in a Randomized Block Design (RCBD) with a 2 x 4 Factorial experiment with 4 replications. The first factor is organic fertilizer consisting of: B0: without manure Bk: 500 grams / staple. The second factor is inorganic fertilizer consisting of: P0: 10 g urea (Control), P1: 10 g urea + 10 g SP-36 + 10 g Kcl, P2: 10 g urea + 15 g SP-36 + 15 g Kcl, P3: 10 g urea + 20 g SP-36 + 20 g Kcl. The results showed that organic fertilizer treatment significantly affected the growth of height, diameter, number of branches, age of flowering, and the number of fruit of cayenne pepper. Inorganic fertilizer treatment (SP-36 and KCL) had no significant effect on the growth and production of cayenne plants. The best interaction is the combination of B0P1 fertilizer (urea + SP-36 + KCL) and BKP0 (urea + manure) treatment. The application of organic and inorganic fertilizers separately is stronger than when applied together. Damage to plants caused by curly diseases in the rainy season due to poor drainage (sub-optimal) land conditions. Application of organic and inorganic fertilizers to be applied separately. Optimal land management is needed by making good drainage to reduce the level of attack of critical diseases, especially in the rainy season.

Abstract

The prospect of cauliflower or in its foreign language cauliflower in east Kalimantan is very promising. The supply of cauliflower at this time is very dependent on outside the East Kalimantan region, namely Java and Sulawesi. The efforts made to meet the needs are to increase production by improving intensive cultivation techniques. The productivity of cauliflower plants can be increased by providing micronutrients and using suitable varieties. The study aims to determine the effect of mikro fitomic and variety nutrients on the growth and production of cauliflower plants. This study was compiled in a Randomized Group Design (RAK) with a 4 x 2 factorial trial with 4 repeats. The first factor is the concentration of mikro fitomic fertilizer (F), which consists of 4 levels: F0: control, F1: 1.5 ml/litre of water, F2: 2.5 ml/litre, F3: 3.5 ml/litre water. The second factor is the variety, which consists of 4 levels V2: PM 126 variety. Fitomic micro fertilizer has significantly affected the growth and production of Brassica oleracea. The crop/plant weight of 884.38 grams was achieved at the optimal concentration of micro-fitomik fertilizer 3.5 ml/litre of water. The Brassica oleracea variety had a significantly affected diameter, plant/plant weight, and plant/plot weight. Plant production/hectare of the PM 126 variety was higher than the production of the Orient variety. The interaction between the concentrations of micro-fitomic fertilizers and the two types of varieties was not significantly different in growth and production. Recommendations for the application of micro-fitomic to B.oleracea plants are applied at a concentration of 3.5 ml/litre of water. PM126 and Orient varieties are suitable for cultivation in the lowlands of East Kalimantan.

Abstract

General Background: Rubber productivity in Indonesia remains low due to suboptimal cultivation practices, including the improper use of stimulants, which can harm plant health. Specific Background: One strategy to increase yield is the application of low tapping frequency combined with Ethrel 10 PA stimulant, which can prolong latex flow and enhance cell metabolism; however, its effectiveness depends on clone type and plant physiological condition. Knowledge Gap: Limited knowledge exists on the optimal combination of tapping frequency and stimulant dosage to sustain productivity without compromising plant health, particularly for PB 260 and GT 1 clones. Aims: To determine the optimal tapping frequency and stimulant dosage for these clones. Results: Field trials revealed that a d/3 tapping frequency yielded the highest latex output, while a dosage of 2 g/tree produced the maximum yield; however, there was no significant interaction between the two factors. High tapping frequency, though productive, risks reducing plant health. Novelty: This study recommends tapping every four days combined with a 1 g/tree Ethrel dosage to balance productivity and plant health. Implications: These findings provide practical guidance for sustainable rubber cultivation, maximizing yield while preserving the productive lifespan of trees. Highlights: Optimal combination of tapping interval and stimulant dosage. Balances high yield with plant health preservation. Practical recommendation for sustainable rubber farming. Keywords: Rubber Productivity, Tapping Frequency, Ethrel 10 PA, Latex Yield, Sustainable Cultivation

Abstract

Farmers generally plant pepper on ultisol soil. Ultisol soil is classified as acid mineral soil which has a wide distribution, but has the potential to develop agricultural land including pepper plantations. The tendency of land used for agricultural activities shows a decrease in soil fertility, indicated by the occurrence of erosion, imbalance of nutrients present in the soil and stronger soil dependence on fertilizer, as well as lower crop production. The research aims to find out the characteristics of pepper land, productivity, potential land for the development of pepper plants in Muara Badak District. This research was carried out using survey methods with stages including; overlaying land maps, interviews, secondary data inventory, in the form of data on the number of farmers, land area, production and cultivation techniques, and analysis of soil samples in the laboratory. The results showed that the population / ha of pepper plants was different for each farmer, where the spacing was 110 x 110 cm, 120 x 120 cm, 130 x 130 cm and 140 x 140 cm with a population between 1300 - 4500 staples / ha. Farmers generally use lodrin organic fertilizer, but are not carried out intensively, and the land management system does not pay attention to the aspect of soil conservation, farmers' land has been cultivated for generations without using terraces and soil cover. The tendency of nutrient loss on the land is quite high because the land is located on a hill and is quite steep at 16-40% slope. Pepper productivity in the study area is quite high, with an average of 1,437 kg / ha. The highest productivity in Salo Palai village reached 1970 kg / ha, while the lowest in Batu Batu village was 830 kg / ha. The results of soil analysis in the two study locations that the content of the element N was classified as medium, the total K was classified as high to very high. pH and CEC are low, this can affect nutrient absorption, so that lime is needed and the addition of organic matter if fertilization is carried out.

Abstract

The factors that influence rubber production are planted clones, plant care and tapping techniques. With the right tapping technique, both tapping time, tapping method and mature tapping age, the production potential of a superior clone of rubber plants that has been well maintained can be maintained. The technique of rubber tapping is closely related to the expected level of production, even very determining the age of the tree economy. The research objective was to determine the effect of stimulant better and tapping time on latex production. The method used was a randomized block design with two-factor split plot design. The first factor (main plot) is the time of tapping consists of 3 levels, namely; w1: 05 in the morning, w2: 06 in the morning, w3: 07 in the morning. The second factor (sub-plot), namely the stimulant dosage better consists of 4 levels, namely; b0: control, b1; 0.5 g, b2; : 1 g, b3; 1.5 g. The results showed that stimulate better treatment had a significant effect on latex volume, wet weight and latex dry weight, but was not significant for latex dryness levels. Tapping time was not significant for latex yield, latex volume, wet weight, latex dry weight and highest dry rubber content at 7am. Stimulant Better treatment has a significant effect on latex volume, wet weight, and latex dry weight, but if given at high doses it will reduce the dry content of rubber. The interaction of treatment when tapping and stimulant is better not significant for latex production. The stimulant application better does not exceed the dose of 0.5 g / principal. Doses> 0.5 g / staple will have an impact on the dry tapping field.
