Moringa Leaf Extract

Moringa is a valuable plant whose leaves are enriched with antioxidants, amino acids, vitamins and mineral nutrients and can be used as a bio-stimulant. A field work was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh, during rabi season from November 2017 to February 2018 in order to investigate the effect of moringa leaf extract (MLE) on growth, yield and nutrient status of cabbage. The experiment was laid out in a randomized complete block design with four treatments and three replications. The treatments were T1 (control), T2 (MLE) sprayed at 2 weeks after transplanting only], T3 (MLE sprayed at 2 weeks and 4 weeks after transplanting), T4(MLE sprayed at 2 weeks after transplanting and after every two weeks thereafter). The rate of MLE application was 25 mL plant-1. All the treatments received recommended dose of N, P, K, S, Zn and B fertilizers. The application of MLE significantly improved the growth parameters, yield and yield contributing characters as well as nutrient content and uptake of cabbage. Among the parameters plant height (33.40 cm), leaf number (19.33 cm), length of the largest leaf (29.00 cm), head thickness (9.67 cm), head diameter (20.33 cm), gross yield (72.83 t ha-1) and marketable yield (48.87 t ha-1), were maximum in T4 where MLE was sprayed at 2 weeks after transplanting and after every two weeks thereafter. The lowest values of all these parameters were found in T1 where no MLE was sprayed. Foliar application of MLE also improved the concentration and uptake of macronutrients (N, P, K and S) in head of cabbage. Thus, application of MLE as a bio-stimulant has the potentiality to enhance growth, yield and nutritional quality of cabbage. Asian J. Med. Biol. Res. June 2020, 6(2): 196-203

Moringa Leaf Extract

Moringa oleifera leaf extract has a potential effect as a growth enhancer of many crops. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the effect of foliar application of moringa leaf extract on growth and yield of late sown wheat (BARI Gom-26). The experiment was laid out in a randomized complete block design with six treatments and three replications. The treatments were T1 (Control), T2 [moringa leaf extract (MLE) sprayed only at tillering stage], T3 (MLE sprayed at tillering and jointing stages), T4 (MLE sprayed at tillering, jointing and booting stages), T5 (MLE sprayed at tillering, jointing, booting and heading stages), and T6 (MLE sprayed only at heading stage). Application of moringa leaf extract significantly increased the growth and yield attributes as well as grain and straw yield of wheat. Among various treatments with moringa leaf extract the performance of T4 (MLE sprayed at tillering, jointing and booting stages) was the best as it produced the tallest plant (87.87 cm), the highest fresh and dry weight of root (16.51 g and 11.37 g respectively), the highest number of spikelets spike-1 (19.70) and filled grains spike-1 (45.53), as well as the highest grain and straw yield (3.62 t ha-1 and 5.43 t ha-1 respectively) of wheat. Therefore, moringa leaf extract as a foliar spray can be applied at critical growth stages to increase the growth and yield potentiality of late sown wheat.Asian J. Med. Biol. Res.

Moringa Leaf Extract

This study examined the effects of moringa leaf extract (MLE) and poultry manure (PM) on the growth parameters of sweet maize. The experiment was a Randomized Complete Block Design involving nine treatments: control (no extract), 3% MLE, 6% MLE, 9% MLE, 3% MLE + 15 t/ha–1 PM, 6% MLE + 15 t/ha–1 PM, 9% MLE + 15 t/ha–1 PM, 15 t/ha–1 PM, and 30 t/ha–1 PM. Data on growth parameters including plant height, number of leaves per plant, stem girth, and leaf area were collected and analyzed. The results of the study show that there were significant differences (P = 0.05) among the treatments because plots that received 30 t/ha–1 PM performed best on plant height (193.6 and 152.8 cm) number of leaves (13.1 and 10.2), stem girth (3.75 and 3.22 cm), and leaf area (584.9 and 402.9 cm2) in both early and late season. This was followed by plots that received 9% MLE and 15 t/ha–1 PM, with values of 189.0 and 152.2 cm; 12.5 and 10.0; 3.58 3.15 cm; and 546.2 and 392.2 cm2, respectively. The study concluded that 30 t/ha–1 PM can be used to yield effective growth parameters in sweet maize and is hereby recommended to extension workers for dissemination to farmers

Soil acidity is commonly ameliorated with lime while little attention is given to the application of molybdenum which is deficient in acid soils. Molybdenum is an important component of the nitrogenase enzyme essential for the symbiotic nitrogen fixing bacteria.  An experiment was conducted in a controlled environment at the University of KwaZulu-Natal to evaluate the effect of lime and molybdenum on nodulation, growth and shoot nutrient content of soybean. The experiment was a randomised complete block design with three rates of lime applied at 0, 2650 and 4280 kg ha-1 and molybdenum as ammonium molybdate at 0 and 0.5 g L-1. Lime significantly (p<0.01) increased the uptake of Ca and P but decreased that of Mn. Also, increasing lime levels positively influenced most of the important plant growth parameters measured in the study. Molybdenum application significantly increased nodule formation but did not influence the concentration and uptake of the nutrients measured. Lime application also improved soil Ca and Mg but reduced Mn and exchangeable acidity levels at the end of the study.  The treatment combination of lime at 4280 kg ha-1 and ammonium molybdate at 0.5 g L-1 gave the best result in nearly all parameters tested and it can hence be concluded that this combination improves both the nutrient uptake and nodulation of soybean grown in soil with very high acid saturation.

Balanced fertilization is a pre-requisite for better rice production and it is necessary to determine optimum combination of nutrient elements for application. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Boro season to investigate the effects of reduced rates of phosphorus (P) and sulphur (S) on the growth, yield, nutrient content and uptake by rice. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and eight treatments viz. T1: Control, T2: Recommended Fertilizer Dose (RFD), T3: RFD -20% P, T4: RFD-40% P, T5: RFD-20% S, T6: RFD-40% S, T7: RFD-20% PS and T8: RFD-40% PS. The recommended fertilizer doses were 125 kg N ha-1, 25 kg P ha-1, 70 kg K ha-1, 15 kg S ha-1 and 3 kg Zn ha-1 supplied from urea, TSP, MoP, gypsum and zinc sulphate, respectively. There was significant effect of reduced rates of P and S fertilizers on rice yield compared to control. The highest grain yield of 5.10 t ha-1 and straw yield of 7.02 t ha-1 were recorded from treatment T2 (RFD) that produced the maximum values of all the yield components and the highest content and uptake of nutrients. The performance of T2 and T3 (RFD - 20% P) was statistically similar in producing yield parameters, yields, nutrient contents and uptake by rice. Again, 20% reduced rate of S (T5) or of P and S (T7) caused significant yield reduction, poor yield parameters and less nutrient uptake compared to T2. Thus, the recommended fertilizer dose and the treatments where 20% P was reduced from the RFD are equally efficient in increasing yield as well as enhancing nutritional quality of rice. This reduction of chemical fertilizer could help lessen the cost of rice production with decreasing environmental risk. Asian J. Med. Biol. Res. March 2021, 7(1): 40-47

Organic Manures

Field experiment was conducted to study the influence of organic manures and biofortification of selenium on growth, yield and selenium contentof cucumber (CucumissativusL.) during 2019 at Koneripalayam village in Perambalur district, Tamil Nadu. The popular variety Green Long suitable for this region was used for the present study. The experiment was carried out during two seasonsviz., Season I (February-May) and Season II (July-October)in randomised block design with fifteen treatments and three replications. The results of the experiment revealed that application of 25 tFYM ha -1 and 2 kg CBF ha -1 along with foliar application of Se (20 µg L-1) significantly recorded the highest vine length (209.1 cm and 214.6 cm), number of leaves (108.2 and 113.7), leaf length (15.7 cm and 15.9 cm) and leaf breadth (16.2 cm and 16.5 cm) in first and second season, respectively. The highest number of fruits per vine (13.3 and 16.5), fruit length (19.6 cm and 20.8 cm), fruit girth (17.1 cm and 18.2 cm), mean single fruit weight (78.1 g and 81.2 g), fruit yield vine-1 (723.5 g and 1009.2 g)and selenium content per fruit (8.1 µg kg-1 and 10.6 µg kg-1) in first and second season respectively was obtained with1 t EM ha -1 + 2 kg CBF ha -1 + Se (20 µg L-1) as foliar application. Among all the organic manures, farmyard manure was proved to be superior in respect of growth parameters and enriched manure in respect of yield parameters. The foliar application of selenium was found to be the best method of its supplementation in plants and relatively higher values of Se content in fruits were noted with higher dose of Se as folior application.
