“…This is supported by the findings of Mostafa and Kader (2006) [33] and Rongfei et al, 2017 [44] , who reported that increased sulphur application significantly increased leaf sulphur content and also increases significantly the fruit length, diameter, weight, total soluble solids, total sugars and yield significantly. This is also in agreement with the findings of Mansour et al (2008) [28] while working on pear. Available soil nutrients and fruit yield Among the macronutrients, available soil nitrogen, phosphorous and calcium showed significant positive relationship with fruit yield in surface soil (Table-7) while as rest nutrients showed positive but non-significant correlation with yield.…”

Apple (Malus domestica Borkh.) one of the rosaceous group is native of Asia Minor to western Himalayas. High density apple orchards developed on semi dwarf rootstock like MM 106 have become common in many apple growing regions of the Kashmir especially North Kashmir. Suitability of soil as a medium of plant growth depends on both its physico-chemical properties and nutritional status. As per the results soils were slightly acidic to slightly alkaline and ranged statically from 6.55 to 7.52 in surface and 7.31 to 7.78 in sub-surface soils. The highest values of organic carbon in surface and sub-surface soils were found in orchards located in high altitude followed by mid and low altitudes orchard soils. The available nitrogen, phosphorus and potassium content varied significantly with altitude and the higher values were observed in HDP apple orchards located in high altitude. The available nitrogen and phosphorus showed a decreasing trend while as available potassium showed irregular with soil depth. The foliar contents of nitrogen, phosphorus and potassium in high density apple were found to be sufficient. The leaf calcium, magnesium and sulphur varied from 1.66 to 1.75, 0.27 to 0.31, and 0.20 to 0.23 per cent respectively. Significantly higher average yield was recorded in high and mid altitudes than low altitude HDP apple orchards. Nutrients showed positive relation with organic carbon. Plants absorb nutrients from both surface as well as sub-surface soils. The present study though first of its kind on high density apple orchards is expected to be quite useful for horticulturists for formulation of future research programme.

The research aimed to examine the enhancement effect of Spirulina platensis (blue-green microalga or Cyanobacterium) and Chlorella vulgaris (green microalga) water extracts as biological stimulant in improving growth parameters, chlorophyll content, yield, and fruit quality of tomato plants under salinity stress. Tomato seeds (Solanum lycopersicum L. of cv. Agyad) were soaked in three microalgae water extracts at a 10% concentration (Chlorella vulgaris, Spirulina platensis, and Chlorella:Spirulina at a ratio of 1:1). Chemical and biochemical analyses for the used materials and products were achieved. After germination, tomato transplants were irrigated with saline water at three levels of saline water (2, 4, and 7 dS/m) using sea salt. Successive grown tomato transplant at 7.0 dS/cm were infused in clayey soil. The grown plants were preyed by algal extract and irrigated by the same solution. Vegetative growth, yield, shelf life, and chlorophylls (a and b) were determined. It was found that the highest vegetative growth, yield, and chlorophyll content were measured in tomato transplants with the Spirulina:Chlorella mixture, followed by Spirulina platensis and Chlorella vulgaris water extracts; all of these measurements increased significantly in response to microalgae treatments. Experimental tomato fruits of Chlorella and mixture treatments can stay for 45 days at room temperature. Both algal extracts and their mixture enhanced the bioaccumulation of micronutrients (Fe, Zn, Mn, and Cu), compared with the control, while Chlorella extract surpassed Spirulina and mixture extracts. Concerning the used dried algae and their water extract, Spirulina platensis surpasses Chlorella vulgaris for protein and ash content.
