The experiment was conducted during the period from March to the end of April 2019 to observe the effect of different fertilizer regimes on the growth, quality and yield of lettuce under field conditions. The experiment was consisting of four treatments as well as a control without fertilizer T1, compost T2, compost tea T3 and chemical fertilizer T4, in each treatment 50 replicates were planted. The measurements included wet and dry weight for shoot and root, plant length, and chlorophyll percentage. The study revealed that lettuce's best growth values were obtained with the use of eco-friendly organic fertilizer accompanied by more than control one and chemical fertilizer. The average maximum length of plants after 60 days were recorded in T2 (42.3 cm) > T3 (37.3 cm), T4 (35.9 cm) and > T1 (23.8 cm). The results indicated that compost treated plant (T2 and tea compost T3) had highest chlorophyll content, i.e. 42.3 and 40.6%, respectively, as compared to chemical fertilizers T4 (37.3%) and the lowest chlorophyll content was in control T1 (30.9%). The values for wet shoot and root after 60 days were: 1575.2, 81.5 gm T2 > 1367.6, 64.9 gm T3 > 1251.1, 53.4 gm T4 and 612.1, 43.7 gm T1, respectively.

SummaryThe utilization of lignocellulolitic emptyfruit-bunches of oil-palm (EFBOP) material asstraw mushroom (Volvariella volvacea) mediacould produce short chain organic carbon andnutrients which may be available for growth ofplant. This research was aimed to determine theeffect of spent mushroom media amendmentderived from empty fruit bunches of oil palm(SMEB) as organic fertilizer on the growth andnutrient uptake of oil palm seedling. Theexperiment was conducted at greenhouse usingacid soil. Oil palm seedling was grown in 60 x 50cm polybags. The experiment was carried out toexamine 20 treatments i.e. combinations of fourlevel of SMEB (0, 25%, 50%, and 75% w/w) andfive dosages of conventional fertilizer (0, 25%,50%, 75%, and 100%) recommended dosages.The experiment was conducted using completerandomized design with factorial type. Theresearch showed that the amendment of SMEB atthe level of 25% could increase the height ofseedling, fresh weight of root, stem, and seedlingsas well as dry weight of oil palm stem. However,for leaf dry weight, a higher addition of SMEB upto 50% was needed. Fertilizing at 25% ofrecommended dosage could increase the seedlingheight, fresh weight of stem and leaf while forseedling fresh weight and leaf number, higheraddition of fertilizer up to 50% was needed.Significantly higher uptake of K and Mg wasobserved on the amendment of 75% of SMEB.The higher addition of SMEB (up to 75% w/w)did not decrease any growth parameters andnutrient uptake. However, the addition of 100%of recommended chemical fertilizer tended todecrease various growth parameters and uptakeof N, P, K, and Mg of oil palm seedling.RingkasanPenggunaan bahan lignoselulosa sebagaimedium jamur merang (Volvariella volvacea)diketahui dapat menghasilkan senyawa karbonrantai pendek demikian pula hara tersedia,sehingga diduga bahan ini dapat digunakansebagai pupuk organik untuk tanaman.

The aim of this study was to compare the effects of four fertilizer applications—control (C), chemical fertilizer (F), compost (O), and in situ earthworm breeding (E)—on the growth, quality and yield of papaya (Carica papaya L.). In this study, 5 g plant−1 urea (CH4N2O, %N = 46.3%) and 100 g plant−1 microelement fertilizer was applied to each treatment. The fertilizer applications of these four treatments are different from each other. The results showed that the E treatment had the highest growth parameters over the whole growth period. At 127 days after transplantation, the plant heights were ordered E > F > O > C, and the stem diameters were E > F > O > C, with significant differences between all treatments. Soluble-solid, sugar, vitamin C, and protein content significantly increased in the E treatment. In addition, the total acid and the electrical conductivity of the fruit significantly decreased in the E treatment. Fruit firmness clearly increased in the O treatment, and decreased in the F treatment. The fresh individual fruit weights, fruit numbers, and total yields were greatly improved in the F and E treatments, and the total yield of the E treatment was higher than that in the F treatment. In conclusion, the in situ earthworm breeding treatment performed better than conventional compost and chemical fertilizer treatments. Furthermore, in situ earthworm breeding may be a potential organic fertilizer application in orchards because it not only improves the fruit quality and yield but also reduces the amount of organic wastes from agriculture as a result of the activities of earthworms.

Abstract Chlorophyll is a green pigment in leaves that functions to absorb light energy for photosynthesis. The value of chlorophyll concentration in leaves indicates the health status of a plant and healthy plants will produce more fruit. The purpose of this study was to determine the effect of chemical fertilizer (CF) and solid algae fertilizer (SAF) with different doses on the concentration of chlorophyll in paddy leaves. This research is important to do to determine the potential of macroalgae in reducing the dose of chemical fertilizer use in agricultural activities. In this study, paddy plants were given four different treatments, namely control (without CF and SAF); 100% chemical fertilizer (CF); 100% solid algae fertilizer (SAF); 50% chemical fertilizers and 50% solid algae fertilizers (CF+SAF). Each treatment consisted of ten pots. The results showed that the administration of SAF in the form of a combination of SAF 50% and CF 50% had a significant effect on the increase of chlorophyll b content of the leaves of paddy plants. However, there were no significant difference in chlorophyll a content between CF and CF+SAF group. Current results show that addition of SAF could potentially increase growth quality in paddy plants due to the increase of chlorophyll b content which absorbs higher frequency of blue light for photosynthesis.

Food waste is a common global threat to the environment, agriculture, and society. In the present study, we used 30% food waste, mixed with 70% bio-fertilizers, and evaluated their ability to affect the growth of Chinese cabbage. The experiment was conducted using different concentrations of food waste to investigate their effect on Chinese cabbage growth, chlorophyll content, and mineral content. Leaf length, root length, and fresh and dry weight were significantly increased in plants treated with control fertilizer (CF) and fertilizer mixed with food waste (MF). However, high concentrations of food waste decreased the growth and biomass of Chinese cabbage due to salt content. Furthermore, higher chlorophyll content, transpiration efficiency, and photosynthetic rate were observed in CF- and MF-treated plants, while higher chlorophyll fluorescence was observed in the MF × 2 and MF × 6 treatments. Inductively coupled plasm mass spectrometry (ICP-MS) results showed an increase in potassium (K), calcium (Ca), phosphorous (P), and magnesium (Mg) contents in the MF and MF × 2 treatments, while higher sodium (Na) content was observed in the MF × 4 and MF × 6 treatments due to the high salt content found in food waste. The analysis of abscisic acid (ABA) showed that increasing amounts of food waste increase the endogenous ABA content, compromising the survival of plants. In conclusion, optimal amounts of food waste—up to MF and MF × 2—increase plant growth and provide an ecofriendly approach to be employed in the agriculture production system.

Calcium-rich vegetables in the diet could ameliorate the potential for calcium (Ca) deficiency in human nutrition. This study investigated the prospect of increasing Ca density of lettuce (Lactuca sativa L.) through cultivar selection and nutrient management in a greenhouse. Eighteen lettuce cultivars including butterhead, romaine, and loose-leaf phenotypes of heritage and modern genetics were tested. Organic fertilizer (3N–0.7P–3.3K) and commercial conventional fertilizer (20N–4.4P–16.6K) factored with three Ca levels (50, 100, 200 mg·L−1 as CaCl2) were the fertilizer regimes. Calcium in whole shoots was analyzed by atomic absorption spectrometry of oven-ashed samples. Heritage cultivars had a significantly higher Ca concentration (1.93% dry weight) than modern cultivars (1.54%). Loose-leaf phenotypes had the highest Ca concentration (2.06%) followed by butterhead (1.66%) and romaine (1.49%). Accumulation of Ca was higher with the conventional fertilizer (1.90%) than with the organic fertilizer (1.58%). Elevated Ca level in the fertility regimes raised the Ca concentration in lettuce from 1.56% at 50 mg·L–1 to a mean of 1.82% at 100 mg·L−1 and 200 mg·L−1. Large differences in Ca concentration occurred among individual cultivars with ranges from 1.27% to 3.05%. ‘Salad Bowl’, ‘Red Deer Tongue’, ‘Buttercrunch’, and ‘Bronze Mignonette’ were the top in cultivar ranking with mean Ca concentration of 2.50%, whereas ‘Adriana’, ‘Australe’, ‘Coastal Star’, and ‘Forellenschluss’ were low accumulators with a mean of 1.33%. Head size of cultivars had no correlation with Ca concentration. This experiment indicates that selection of nutrient regimes and cultivars can be used to increase Ca accumulation in lettuce.
