Exogenously Applied Moringa Leaf Extracts and Mixed Fertilizers in Soil to Improve Growth and Yield of Tomato (Lycopersicon Esculentum Mill.)

Abstract

Sustainable production of horticultural crops demand judicious application of integrated nutrient management and biostimulant like moringa leaf extract (MLE) which provides different macro and micronutrient including phytohormones. Two factors experiment was laid out in randomized complete block design (RCBD) with 3 replications to observe fertilizers and moringa leaf extract (MLE) effects on growth and yield of tomato. Fertilizer were F0 (control), F1 (vermicompost), F2 (inorganic fertilizer), F3 (2/3 F1 + 1/3 F2). Foliar application of MLE were M0 (control), M1, M2 and M3 where MLE sprayed at one, two-and three-weeks interval after transplanting, respectively. In case of fertilizers, F3 gave the highest growth, 54.65%, 13.67% and 12.65% higher yield of tomato compared to sole application of vermicompost (F1), inorganic fertilizer (F2) and control (F0), respectively. In case of MLE, the highest growth and yield was found from M1; and the yield was 42.38 % higher compared to control. Among the treatments combination, the highest growth and yield like plant height (59.90 cm), flowers/plant (57.08), fruits/plant (25.67), fruit diameter (5.00 cm), fruit length (6.83 cm), individual fruit weight (67.65g), yield (1.52 kg/plant and 57.00 t/ha) was found from F3M1 and the lowest was found from F0M0. Our results suggested that about 75% less amount of inorganic fertilizer with judiciously incorporated vermicompost and exogenous application of MLE at one week interval could be used to improve the quality and productivity of tomato; and this can sustain the sustainable horticulture technology as environmentally friendly.

Effect of fertilizers and mulching on growth and yield of sweet pepper (Capsicum annum L.)

“…Similarly, Biswas et al (2020) found highest yield at this treatment in tomato. F 4 treatment gives the highest dry matter content (4.94%) and lowest was found from the F 1 treatment.…”

“…This reduces the need for a higher amount of inorganic fertilizer in crop production. Ultimately, application of reduced amount chemical fertilizer combined with judicious application of organic fertilizer sustain the quality of soil properties and product quality (Islam et al, 2017ab;Biswas et al, 2020) found that about 75% less amount inorganic fertilizer and judiciously incorporated vermicompost as organic fertilizer increased the 198% yield of tomato. Water is a natural resource and essential for crop production.…”

WRKY22 Transcription Factor from Iris laevigata Regulates Flowering Time and Resistance to Salt and Drought

“…Ion imbalance can last a few days or even weeks in tender parts of the plants such as the bud [10]. It further induces secondary oxidative stress, leading to the inhibition of photosynthesis and metabolism and ultimately a deduction in plant yield [11]. Similar to high salinity, drought causes osmotic stress and secondary stress including oxidative stress, damage to cellular components, and metabolic dysfunction [10].…”

Production of Summer Vegetables Using Conservation Agriculture Techniques: Experiences from Northern Bangladesh

“…Vegetable growing with excessive inorganic fertilizers and inappropriate application of pesticides is now a common practice in Bangladesh to achieve higher yield. However, judicious combination of soil organic and inorganic fertilizers, and proper management might improve soil physical properties and nutrient towards enhance crop yield (Habib et al 2012;Afrin et al 2019;Biswas et al 2020;Farjana et al 2019). Sustainable management of soil and vegetable production are now getting enormous importance in Bangladesh in order to main soil environment.…”
