A greenhouse experiment was conducted at the Indian Institute of Horticultural Research (IIHR), Bangalore to study the interaction effect between phosphorus (P) and zinc (Zn) on the yield and yield attributes of the medicinal plant stevia. The results show that the yield and yield attributes have been found to be significantly affected by different treatments. The total yield in terms of biomass production has been increased significantly with the application of Zn and P in different combinations and methods, being highest (23.34 g fresh biomass) in the treatment where Zn was applied as both soil (10 kg ZnSO4/ha) and foliar spray (0.2% ZnSO4). The results also envisaged that the different yield attributes viz. height, total number of branches, and number of leaves per plant have been found to be varied with treatments, being highest in the treatment where Zn was applied as both soil and foliar spray without the application of P. The results further indicated that the yield and yield attributes of stevia have been found to be decreased in the treatment where Zn was applied as both soil and foliar spray along with P suggesting an antagonistic effect between Zn and P.

A greenhouse experiment was conducted at the Indian Institute of Horticultural Research (IIHR), Bangalore to study the interaction effect between phosphorus and zinc on their availability in soil in relation to their contents in stevia (Stevia rebaudiana). The results show that the amount of available P and Zn content in soil has been found to increase initially and, thereafter, the amount of the same decreased with the progress of plant growth up to 60 days irrespective of treatments. The amount of P and Zn in soils showed an increase with their separate applications either as soil or foliar spray while that of the same value significantly decreased both in soils and plants due to their combined applications, suggesting a mutual antagonistic effect between Zn and P affecting each other’'s availability in soil and content in the stevia plant.

A field experiment was conducted comprising two varieties of mungbean, BARI Mung-5 (V1) and BARI Mung-6 (V2), and five levels of phosphorus fertilizer: triple super phosphate [Ca(H<sub>2</sub>PO<sub>4</sub>)] viz. T1 (control), T2 (42.5 kg P ha<sup>−1</sup>), T3 (85 kg P ha<sup>−1</sup>), T4 (127.5 kg P ha<sup>−1</sup>), and T5 (170 kg P ha<sup>−1</sup>). The experiment was organized in a randomized complete block design with three replications. V1 produced the highest number of pods per plant (7.65), whereas the maximum 1,000-seed weight (49 g) was produced by V2. The maximum plant height (30.89 cm), number of branches per plant (8.55), number of leaves per plant (19.05), number of pods per plant (10.25), pod length (8.95 cm), number of seeds per pod (9.11), 1,000-seed weight (48.17 g), and yield (1.05 t ha<sup>−1</sup>) were obtained from the T4 treatment. The interaction of phosphorus levels and varieties had a considerable effect on the growth, yield, and yield attributes of mungbean. The highest number of leaves (20.44) and number of pods (10.39) were obtained from V1 when 127.5 kg P ha<sup>−1</sup> (T4) was applied, whereas the maximum number of seeds per pod (9.25) and maximum pod length (9.09 cm) were obtained when  85 kg P ha<sup>−1</sup> and 42.5 kg P ha<sup>−1</sup>, respectively, were used. The highest number of branches per plant (8.87), 1,000-seed weight (52.83 g), and the maximum seed yield (1.14 t ha<sup>−1</sup>) were achieved from the treatment V2T4 owing to the interactive effect of phosphorus dose and mungbean variety.

Variety having proper response to phosphorus for proper nutrient uptake and the optimum level of phosphorus for higher  yield may be a way of increasing production and productivity in the context of Nepal. This experiment  was carried out in Lamahi Municpality, Dang district of the Province no: 5, inner terai region of Nepal during the rainy season, 2019. The objective of the experiment was to study the effect of different phosphorus level on growth and development of different varieties of cowpea. The experiment was laid out in two factorial RCBD with two varieties (Aakash and Prakash) and five phosphorus level (0 kg ha-1, 20 kg ha-1, 40 kg ha-1, 60 kg ha-1 and 80 kg ha-1). The result revealed that variety Aakash showed the significantly higher yield of fresh pod (15.99 t ha-1) and yield attributing parameters like number of leaves at 45 DAS (35.22), leaf area at 45 DAS (70.23 cm²), pod diameter (0.77 cm), total number of fresh pods per plant (44.85) than Prakash variety (yield; 12.25 t ha-1). The parameters like number of branches and pod length were not affected by the variety used. In addition, the different level of P also affects the yield of the fresh pod of different varieties. The P level 40 kg ha-1 reported highest yield of fresh pod (20.18 t ha-1 and showed significantly higher number of leaves (38.9), number of branches (23.48), plant height (88.78cm), leaf area (81.89 cm²), pod length (17.76 cm), pod diameter (0.79 cm) and total number of fresh pods per plant (55.19) whereas control produced the lowest total yield of fresh pod (8.33 t ha-1), control (30.99) and 80 kg P ha-1 (30.86) produced the least number of leaves, control produced the least number of branches (17.31), control (63.77 cm) and 80 kg P ha-1 (67.83) produced the shortest plant, 80 kg P ha-1 produced the minimum leaf area (51.09 cm2), control produced least pod length (14.3 cm), pod diameter (0.74cm), total number of fresh pods (34.29). Similarly, interaction of Aakash and phosphorus dose 40 kg ha-1 produced significantly maximum number of leaves (43.07) and total yield of fresh pods (23.33 t ha-1). The results of the experiment revealed that variety Aakash with the phosphorus level 40 kg ha-1 seems the more profitable in Terai and inner Terai condition of Nepal. However, the results need to be confirmed for other varieties used by farmers in the region.

Abstract Purple coneflower (Echinacea purpurea (L.) Moench) is classified as medicinal plant comes from North America and not much developed in Indonesia. E. purpurea can be developed by utilizing suboptimal land such as saline land. This study aims to determine the effect of CaCl2 concentration on growth and proline accumulation of three accessions E. purpurea. This study used a Completely Randomized Design (CRD) with 2 factors and five replications. The first factor is three accessions E. purpurea (accession 1; 2; and 3). The two factor is four concentrations CaCl2 (0; 2500; 5000; and 10000 ppm). The observations are plant height, number of leaves, number of branches and proline accumulation. Data were analyzed using SPSS to test difference. The results showed that highest concentration of CaCl2 can inhibit growth and increase proline accumulation. The highest proline accumulation in accession 2 was 22.8002 µmol g−1, accession 2 as an indicator of accession tolerant to salinity.

This study proposes the machine learning based classification of medical plant leaves. The total six varieties of medicinal plant leaves-based dataset are collected from the Department of Agriculture, The Islamia University of Bahawalpur, Pakistan. These plants are commonly named in English as (herbal) Tulsi, Peppermint, Bael, Lemon balm, Catnip, and Stevia and scientifically named in Latin as Ocimum sanctum, Mentha balsamea, Aegle marmelos, Melissa officinalis, Nepeta cataria, and Stevia rebaudiana, respectively. The multispectral and digital image dataset are collected via a computer vision laboratory setup. For the preprocessing step, we crop the region of the leaf and transform it into a gray level format. Secondly, we perform a seed intensity-based edge/line detection utilizing Sobel filter and draw five regions of observations. A total of 65 fused features dataset is extracted, being a combination of texture, run-length matrix, and multi-spectral features. For the feature optimization process, we employ a chi-square feature selection approach and select 14 optimized features. Finally, five machine learning classifiers named as a multi-layer perceptron, logit-boost, bagging, random forest, and simple logistic are deployed on an optimized medicinal plant leaves dataset, and it is observed that the multi-layer perceptron classifier shows a relatively promising accuracy of 99.01% as compared to the competition. The distinct classification accuracy by the multi-layer perceptron classifier on six medicinal plant leaves are 99.10% for Tulsi, 99.80% for Peppermint, 98.40% for Bael, 99.90% for Lemon balm, 98.40% for Catnip, and 99.20% for Stevia.
