Effect of integrated nutrient management on dry herbage yield, nutrient uptake and profitability of French Basil (Ocimum basilicum L.)

Field experiments were conducted at ICAR - Indian Institute of Horticultural Research, Bengaluru during Kharif season of 2015 and 2016 with nine treatments and three replications in a randomized block design to find out the effect of integrated nutrient management on dry herbage yield, nutrient uptake and economics of sweet basil (Ocimum basilicum). The results revealed that the conjunctive use of inorganic fertilizer along with FYM increased the dry herbage yield and nutrient uptake of sweet basil. Application of recommended FYM (10 t/ha) along with recommended NPK (160:80:80 kg/ha) registered the highest dry herbage yield (8.43 and 3.76 t ha- 1) in the main crop and ratoon, respectively and maximum uptake of nutrient in the main crop as N (155.67 and 113.19 kg/ha), P (43.80 and 32.43 kg/ha) and K (163.33 and 116.16 kg/ha) and in ratoon (56.43 and 26.65 kg ha-1), (16.14 and 14.01 kg ha-1) and (55.65 and 39.27 kg ha-1) in 2015 and 2016 respectively. Highest B: C ratio (5.49) was obtained with application of full dose of recommended NPK fertilizer during 2015. While in 2016, the maximum B: C ratio (3.71) was recorded with application of recommended dose of NPK (160:80:80 kg/ha) + FYM (10 t/ha)

Groundwater Geochemistry of Neyveli Lignite Mine-Industrial Complex, Tamil Nadu, India and Its Suitability for Irrigation

This study was undertaken to assess the quality of groundwater for irrigation and level of trace metal concentration in the surface and groundwater bodies from Neyveli lignite mine-industrial complex which is located in Cuddalore district, Tamil Nadu, India. The hydrogeology of the Neyveli groundwater basin is extremely complex, consisting of a series of productive, confined aquifers below the lignite seam in both Mine I and II areas, while a semi-confined aquifer lies above the seam and occurs only in the Mine II area. The suitability of groundwater quality for agricultural purposes in and around Neyveli lignite mine-industrial complex was assessed by measuring physicochemical parameters, including major cation and anion compositions, pH, total dissolved solids, electrical conductivity, and trace metals. The results of the chemical analysis of the groundwater showed that concentrations of ions vary widely and the most prevalent water type is mixed CaNaHCO3, followed by other water types: mixed CaMgCl types and NaCl which is in relation with their interactions with the geological formations of the basin, dissolution of feldspars and chloride and bicarbonate minerals, and anthropogenic activities. The most dominant class is C1-S1, C2-S1 (85% PRM and 74% POM) in the study area, indicating that sodicity is very low and salinity is medium, and that these waters are suitable for irrigation in almost all soils.Based on sodium absorption ratio the groundwater of the study area is suitable for all types of crops and soil except for those crops sensitive to Na and based RSC values of the groundwater, considered safe. Based on the parameters such as TDS, EC, SO4, Cl and Wilcox diagram about 99% of samples are suitable for irrigation. The average concentration of trace metals (Fe, Mn, Cr, Zn, Pb, and Cu) in groundwater samples fall within the permissible limit, with the exception of Ni which is recorded higher than the permissible limit which may retard growth and metabolic activities while the groundwater used for irrigation

Aeroponics approach for production of gladiolus (Gladiolus hybridus Hort.) corms and cormels

Gladiolus is a popular commercial flower crop among top ten cut flowers of international trade. In order to improve the rate of multiplication, eleven gladiolus varieties with three nutrient regimes (N1- 96:18:108, N2-128:24:144 and N3-160:30:180 ppm of NPK) were evaluated under aeroponics system. The results revealed that different varieties and nutrient regimes had significant influence on plant growth, corm and cormel production. Among the genotypes, Arka Naveen recorded maximum plant height (109.44 cm), on par with Arka Amar (104.77 cm). The genotype Arka Amar (1.89) recorded highest number of corms per plant, on par with Arka Ranjini (1.78), Arka Aayush (1.44), Arka Naveen (1.44) and Arka Shobha (1.67). However, number of cormels were recorded highest in Arka Aayush (1.67), on par with Arka Amar (1.67) and Arka Ranjini (1.44). Among the nutrient regimes, N2 (128:24:144 ppm NPK) registered maximum plant height (85.44 cm), on par with N3 (160:30:180 ppm NPK) (77.42 cm). The number of corms (1.39) and cormels (3.56) per plant were recorded highest in N2 (128:24:144 ppm of NPK). The genotype Arka Manorama did not produce cormels under aeroponics system. Gladiolus varieties Arka Amar, Arka Aayush and Arka Naveen were found as best suited under aeroponic system for better corm multiplication under the nutrient regime of N2 (128:24:144 ppm of NPK)

Stionic effects on leaf mineral nutrient contents in Pummelo (Citrus maxima Merr.) grafted on different rootstocks

A study was conducted to determine the mineral nutrients concentration in the index leaf of pummelo accessions. Index leaf samples from 25 pummelo accessions grafted on pummelo and 12 pummelo clones grafted on Rangpur lime rootstocks were collected for assessing leaf mineral nutrient status. The results revealed that pummelo plants grafted on pummelo, the concentration of leaf N (1.43-2.49 %), P (0.17-0.22 %), K (0.75-4.45 %), Ca (2.37-6.29 %), Mg (0.60-1.04 %), S (0.06-0.22 %), Fe (124-245.45 mg kg-1), Mn (9.85-50.05 mg kg-1), Zn (17-69 mg kg-1) and Cu (8.8-25.15 mg kg-1) showed significant variation with different accessions. Out of 25 pummelo accessions, twenty-four accessions were deficient in N and S, fourteen were deficient in K, four were deficient in Mn and five were deficient in Zn and all accessions were sufficient in P, Ca, Mg, Fe and Cu. The observed trends in the leaf nutrient concentration of pummelo accessions clearly indicated the significance of the genotypic variation when chemical analysis is used for diagnosing the leaf nutrient status of pummelo trees. Similarly, leaf N, P, K, Ca, Mn, Cu and Zn varied significantly among twelve pummelo clones grafted on Rangpur lime. Among the clones grafted on Rangpur lime, 18-3 and 18-5 found to have higher and lower leaf nutrient content in most of the mineral nutrients, respectively. The leaf nutrient content of pummelo varies among genotypes, but there is no genotype that stands out in all macro and micronutrients evaluated. The N, P, K, Ca, S, Fe, Mn and Cu leaf contents in pummelo were always higher in plants grafted on Rangpur lime. However, the foliar Mg and Zn contents were continually higher in plants grafted on ‘pummelo’ compared to Rangpur lime which eventually reduces leaf yellowing/chlorosis in pummelo. Pummelo rootstocks were found to respond well in terms of Mg and Zn nutrient uptake and tolerance to Phytophthora as compared to Rangpur lime. Therefore, it is concluded that pummelo can be an ideal rootstock for commercial pummelo cultivatio

Investigation on promising progenies of Dragon fruit (Hylocereus spp.)

Dragon fruit (Hylocereus spp.) is an exotic vine cactus, rich in vitamin C and antioxidants, commonly known as ‘pitaya’ is a weather resilient crop. In order to develop superior varieties, a large number of progenies obtained from open pollinated seedling of cvs. Hiryur red, Vietnam pink and Vietnam red were raised and evaluated. To broaden the genetic base with desired traits, seeds of Hirehalli red and Hirehalli white were irradiated with gamma rays (500, 600 and 700 Gy), EMS (2.25, 2.5 and 2.75%) and sodium azide (0.04, 0.05 and 0.06%) and evaluated for horticultural traits. Three elite progenies such as CHESH-D1, CHESH-D2, and CHESH-D3 were obtained from open pollinated seedlings of cvs. Hiryur red, Vietnam red and Vietnam pink, respectively, and one EMS (2.5%) treated mutant i.e. CHESH-DE were selected based on their morphological and yield traits. The selection CHESH-D1 performed superior with highest fruit weight (507.71 g) and yield (39.50 kg/ pole) compared to CHESH-D2 and CHESH-D3. The biochemical characters namely, TSS (15.35 oB), total sugars (5.95 g), reducing sugars (4.91 g) and betalains (21.2 mg BCE) were recorded highest in CHESH-D2, and one EMS (2.5%) treated mutant from cv. Hirehalli red showed better adaptability and dwarfness. These elite progenies are at final stage of performance assessment to be released as variety in India

The Psychological States of Beggars in Malaysia: Happiness, Subjective Well-Being, and Gratitude

The economic downturn causes a fluctuation of Malaysian beggars with disrupted psychological states. The research focuses on happiness, subjective well-being, and gratitude among the beggars in Kuala Lumpur and Selangor. Ten beggars participated in an in-depth interview. Their selection was based on a purposive sampling technique. Findings show that with life satisfaction and maintained health conditions, they would be contented. Intolerable circumstances currently made the beggars wishing they could restart an ideal life to restore their subjective well-being. Amidst gratefulness, beggars tend to wake up with an appreciation for every little thing. However, the limited psychological care given has caused the number of beggars to escalate. The number of beggars would dwindle by appraising the public with what they necessitate through an awareness brought by findings from the study

Influence of organic and inorganic fertilizers on yield and quality of sweet basil (Ocimum basilicum L.)

Field experiments were carried out during Kharif season of 2015 and 2016 to study the influence of FYM, inorganic fertilizers and bio-fertilizers on fresh herbage yield, quantity and quality of essential oil of sweet basil (Ocimum basilicum). Nine treatments with  three replication were adopted in a randomized block design to find out the effect of different levels of N applied through FYM (100, 75 and 50% of the recommended N along with and without bio-fertilizers), recommended dose of NPK (160:80:80 kg ha-1), recommended FYM (10 t ha-1) + NPK (160:80:80  kg ha-1) and control (recommended  FYM (10 t ha-1) on fresh herbage and oil yield, oil content and oil quality of sweet basil (Ocimum basilicum L.). Pooled results revealed that application of recommended FYM (10 t ha-1) along with recommended NPK (160:80:80 kg ha-1) recorded the highest fresh herbage yield (39.95 and 19.37 t ha-1), essential oil content (0.48 and 0.45%) and essential oil yield (199.7 and 107.58 kg ha-1) in the main crop and ratoon, respectively. With respect to oil quality, bio-fertilizer has a good impact on oil quality, that highest percentage of Methyl chavicol was recorded with application of recommended FYM (10 t ha-1) + recommended N through FYM along with bio fertilizers in the main crop of 2016 (63.78%) and in the ratoon (59.39 and 59.67%) of 2015 and 2016, respectively
