    Abstract Two novel series of pyrazole and thiophene-linked quinoline analogues via amide bond were conveniently synthesized and characterized by IR, NMR, and HRMS analysis. The synthesized compounds were evaluated for their antimicrobial, anti-inflammatory, and anti-leukemic activity. The antimicrobial evaluation of the target compounds clearly showed that compound 11c has better activity compared to other compounds against tested pathogens. The anti-inflammatory assay of the selected compounds showed that 12c with IC50 value 118.73 µg/ml exhibited significant activity than standard drug Aspirin (IC50, 107.75 µg/ml). The compound 12a out of the twelve newly prepared quinoline heterocycles displayed superior antileukemic activity and was comparable with the standard drug against human monocytic leukemia cell lines (THP-1). Representing the two different quinolinyl-pyrazole/thiophene analogues, compounds 11d, 11e, and 12a displayed the remarkable cytotoxicity against THP-1 cell lines with IC50 values 112.46, 105.42, and 98.88 µg/ml respectively.

    Abstract Turmeric (Cucruma longa L.) grown under various photo-selective nets, sprayed with different elicitors manifested significant differences in growth, yield and quality during both the years of experimentation. The pooled data over two growing seasons clearly revealed that, turmeric under red photo-selective net with chitosan at 1000 ppm manifested highest plant height (106.50 cm) and number of leaves (22.99). While, plants grown under blue photo-selective net without any elicitors outperformed as compared to other treatment combinations in respect of number of tillers per plant (6.58). Yellow net with salicylic acid at 100 ppm recorded highest leaf area (5602.8 cm² plant⁻¹). The blue net with 1000 ppm chitosan resulted in maximum chlorophyll content (SPAD value 42.11). The yellow photo-selective net had a most positive impact on the major yield determinant, the number of primary rhizomes per plant (16.68), while the metabolic elicitors had no influence. Yellow net was superior in terms of fresh (58.27 t ha⁻¹) and cured rhizome yield (15.53 t ha⁻¹) and none of the elicitors had any significant influence on yield. The dry recovery was highest in yellow net and sprayed with active dry yeast at 5000 ppm (27.78%). Curcuminoid content, the major quality determinant was highest in blue net (5.09%) sprayed with chitosan at 1000 ppm. Provision of yellow photo-selective net (25% shade) along with 5000 ppm active dry yeast applied at monthly interval starting from one month after planting up to five months after planting could be recommended for obtaining highest yield and better quality turmeric with highest net returns. Farmers growing turmeric crop under open field condition may spray salicylic acid at 100 ppm to realize higher yield and net returns.

    Abstract Ginger (Zingiber officinale Rosc.) is an important spice crop cultivated for its fresh and dried rhizomes. Ginger never sets seed and sexual recombination has never been reported. Cultivars have evolved by unconscious selection and are generally known by the name of the region. Moreover, it is propagated vegetatively and hence, differentiation of genotypes morphologically is difficult. Twenty-seven ginger genotypes were characterized morphologically using DUS guidelines for eight quantitative and two qualitative characters. Among the characters, four characters were monomorphic, four were dimorphic and two were found to be polymorphic. Grouping of genotypes showed narrow variability for most of the morphological characters whereas, rhizome characters exhibited remarkable variability.

    Abstract Long pepper (Piper longum L.) spikes and roots forms one of the important constituents in the treatment of various human ailments under ayurveda, siddha and unani medicine systems of India. An experiment was conducted in this crop to study the effect of various combinations of organic manures and bio-fertilizers on crop growth, nutrition and soil fertility status including microbial population after harvesting of the crop. Varied levels of farm yard manure (FYM - 30 and 40 t ha-1), vermicompost (VC - 1 and 2 t ha-1), neem cake (NC - 1 and 2 t ha-1) and bio-fertilizers (Azospirilum, phosphate solubilizing bacteria and vesicular arbuscular mycorrhizae each at 10 kg ha-1) were tried in sixteen different combinations. After three years of experimentation the impact of organic farming on soil and plant nutrient status has been analyzed. The results revealed that the application of organic manures has a significant impact on plant and soil nutrient status after three years of cropping. The highest tissue nutrient content and nutrient uptake were recorded in the treatment FYM 40 t + VC 2.0 t + NC 2.0 t + BF 10 kg ha-1 where the organic manures and bio-fertilizers were applied at highest level. The same treatment has also increased the organic carbon, available NPK and microbial population in the soil after three years of cropping. All these parameters were lowest in treatment FYM 30 t + VC 1.0 t + NC 1.0 t ha-1 where manures were applied in lowest quantity without bio-fertilizers. Hence, we conclude that the long pepper is an organic matter loving crop and application of higher levels of organic manures improved both plant and soil nutrient status.

    Abstract The essential oil of 28 ginger genotypes was subjected to gas chromatography–mass spectrometry to understand the potential of these genotypes to produce high essential oil with added value. The essential oil and its composition varied among genotypes. The highest essential oil and oleoresin (6.00 and 12.18 %) was recorded in ‘Red ginger’ (Z ingiberofficinale var. rubrum). Among the ginger (Z. officinale) genotypes, high oil and oleoresin (3.00 and 8.55 %) were recorded in ‘Arunachal local’. The genotypes ‘Acc. 578ʹ, ‘Nadia’ and ‘Aswathi’ recorded less fiber and ‘Red ginger’, ‘Acc. 219ʹ, ‘Arunachal local’ and ‘Acc. 833ʹ recorded high fibre. The Zingiberene was the major component in the essential oil and highest was recorded in ‘Maran’. Principal component analysis revealed essential oil, oleoresin, camphene, trans-nerolidol, α farnesene and neral contributed to genetic diversity. The results contribute to the selection of ginger genotypes for high essential oil and different end use.

    Abstract Sandalwood (Santalum album L.) is a hemiparasite unable to absorb the required nutrients directly from the soil. Therefore, it needs a suitable host for successful cultivation. The effect of hosts on the growth and development of sandalwood was studied in an eleven-year-old plantation in the Northern dry zone of Karnataka. The sandalwood trees grown with Prosopis (Prosopis juliflora L.) exhibited better growth in terms of tree height (6.58 m), canopy spread (4.64 m), canopy volume (48.60 m³), stem girth (40.70 cm), main stem volume (36.79 dm³) and its annual increment (16.39%). They were also summer hardy and recorded higher chlorophyll, free proline, and soluble sugar in leaves. The summer leafiness of sandalwood was associated with the free proline content in its leaf (r = 0.927), which was in turn correlated with the free proline content in leaves of their respective hosts (r = 0.899). The sandalwood trees with Prosopis also exhibited signs of early heartwood development, thus making Prosopis a suitable host for the commercial cultivation of sandalwood in hot semi-arid conditions.
