Fermented compost and N-fertilizer for enhancing the growth and productivity of purple eggplant on vertisols

AbstractThe soil fertility and nutrient availability are limiting factors for growth and plant development. Fermented compost and nitrogen (N)-fertilizer are useful as sources of nutrients to support the growth of plant and microorganisms in soils. The combination of biological fertilizer and chemical fertilizer can support the concept of sustainable and integrated agriculture and minimize the adverse effects of chemical fertilizers. The research was conducted to get the recommended dose of fermented compost and N-fertilizer to increase the plant height and productivity of purple eggplant. The experiment was arranged as factorialized randomized block design and consisted of two factors and two replications, namely fermented compost dose (0, 5, 10, and 15 t ha−1) and N-fertilizer dose (0, 75, 150, and 225 kg ha−1). The observed responses were increase in plant height and productivity of purple eggplant. Compared to the control, the application of 15 t ha−1 fermented compost and 225 kg ha−1 N-fertilizer increased the plant height by 40.76% at 30 days after planting and 57.59% at 37 days after planting and increased the purple eggplant yield by 43.15%. BC ratio of the fermented compost (15 t ha−1) is 1.16 and BC ratio of the N-fertilizer (225 kg ha−1) is 1.09. Recommended dose to increase the plant height and productivity of purple eggplant in vertisol is 15 t ha−1 of fermented compost and 225 kg ha−1 of N-fertilizer.

Drought is one of the limiting factors for the growth and yield of coffee plants. Drought due to long dry season has caused many losses for coffee plantations. This study aimed to evaluate the response of four Robusta coffee clones to drought stress at seedling stage and determine the best clone with high tolerance to drought. The study was conducted in Indonesian Coffee and Cocoa Reseach Institute (ICCRI) Jember, East Java in November 2018–Mei 2019. The experimental design used a Randomized Block Design (RCBD) with two factors. The first factor has consisted of five levels drought through providing volume watering based coefficient and evaporation value of free water surface (Eo), namely: 0.5 Eo; 1.0 Eo; 1.5 Eo; 2.0 Eo; 2.5 Eo (control). The second factor has consisted of four Robusta coffee clones, namely: BP 409 (drought tolerant clone); BP 308; BP 939 and BP 358 (vulnerable to drought stres). The result showed that reduction in the volume of watering from 2.5 Eo until 0.5 Eo causes drought, reduce coffee growth linearly. Clone BP 409 and BP 939 had better tolerance of drought stress compared with BP 308 and BP 358. The anatomical adaptation of leaves of BP 409 to drought stress was by thickening of wax layer and palisade tissue. BP 939 thickened its leaves due to drought stress as a mechanism of adaptation to such condition.

The application of integrated agriculture is an effort to reduce dependence up on agrochemicals and increase the absorption of nutrients, especially nitrogen, to increase plant growth and production. Azolla is an algae that can provide nitrogen for rice, while ducks can increase the availability of N, P, and K, as well as the efficiency of nitrogen use. This research aimed to evaluate the role of ducks and Azolla in increasing the growth and production of rice plants. This research was conducted from October 2018 to February 2019 using an experimental method with a nonfactorial randomized block design. The combinations of nitrogen fertilizers, Azolla, and ducks (K) were as follows: K1 = 115 kg N ha−1, without ducks, without Azolla; K2 = 86 kg N ha−1, without ducks, 1,000 kg Azolla ha−1; K3 = 86 kg N ha−1, 3,000 ducks ha−1, 1,000 kg Azolla ha−1; K4 = 58 kg N ha−1, 3,000 ducks ha−1, 1,000 kg Azolla ha−1; K5 = 29 kg N ha−1, 3,000 ducks ha−1, 1,000 kg Azolla ha−1; and K6 = without N fertilizer, 3,000 ducks ha−1, 1,000 kg Azolla ha−1. The results showed that the application of 58 kg N ha−1, 3,000 ducks ha−1, and 1,000 kg Azolla ha−1 (K4) was able to decrease the N fertilizer application by 50% and increase the rice growth and yield by 12.17% and 20.32%, respectively. Therefore, the integrated application of rice–duck–Azolla would support sustainable agriculture.
