One of the major constraints of onion farming in Pakistan is poor nursery due to adoption of traditional planting methods and overfertilization, which ultimately increases cost of production and loss of resources. The current study, comprised of two experiments, was carried out at Vegetable Area, University of Agriculture Faisalabad, to determine the most suitable nursery raising system and fertilizer application rate for onion nursery in order to get maximum plant population of good quality seedlings. The first experiment comprised of four different nursery growing methods: (1) flat bed + broadcast sowing, (2) flat bed + line sowing, (3) raised bed (6 inches height from ground surface) + broadcast sowing, and (4) raised bed + line sowing. The largest plant population, and highest plant fresh and dry weights...

Due to ion accumulation, salinity stress results in lowering growth rate and water uptake. This issue is being solved by the use of several plant growth regulators. Plant growth regulators have been proven to increase plants' ability to withstand against stress. In this study, turnip (purple top cultivar) was subjected to four distinct levels of salt (0, 4, 8, and 12 dS/m), as well as one level of gibberellic acid, in order to assess the function of exogenously applied plant growth regulator glutamic acid (GA) (10 mM). Results revealed that salt stress slowed plant growth and decreased the amount of chlorophyll in turnip leaves. Application of salt alone resulted in a considerable decline in biochemical characteristics. However, in salt-stressed conditions, exogenous application of GA improved the antioxidant activity, chlorophyll contents and pl...

Two substrates (cotton waste and sorghum straw) were used alone and with different combinations. Experiments consisted of five treatments T 0 (100% Cotton Waste), T 1 (100% Sorghum Straw), T 2 (75% Sorghum Straw + 25% Cotton Waste), T 3 (50% Sorghum Straw + 50% Cotton Waste) and T 4 (25% Sorghum Straw + 75% Cotton Waste). Data concerning time taken for spawn run initiation, mycelial growth completion, pinheads initiation, total number of pinheads, time required to harvest 1 st , 2 nd and 3 rd flush, fresh weight of 1 st , 2 nd and 3 rd flush harvested, total yield, pH, total soluble solids, acidity, ascorbic acid contents, total nitrogen, phosphorus, potassium contents, reducing sugars, non-reducing sugars...

This experiment was conducted at Institute of Horticultural Sciences, University of Agriculture, Faisalabad during 2014, to evaluate the effect of seed treatment with PGPRs viz., Azotobactor spp., Phosphorus solubilizing bacteria (PSB), Germinator (Ger; a synthetic germination and early growth enhancer) and PSB+Ger in combination with full (recommended dose of fertilizer; RDF), half dose of nitrogen, and half dose of phosphorus on yield of radish ( Raphanus sativus L.) cv. ‘Mino Early’. The results showed that Azotobactor spp. improved plants and yield related attributes, while germinator negatively affected them. Number of leaves per plant, root fresh weight, and marketable yield were significantly high owing to the combined application of PSB and RDF. While, leaf fresh weight, above...

Naturally it grown in different locations of Pakistan i.e. Swat, Miandam, Kalam, MalamJabba, Parona, Kokaria, Jambile and Madian etc.Traditionally Morchella esculentais used as medicines in different countries like Japan, China and Malaysia for healing of different diseases and is famous due to its unique flavor and taste.

Pollen viability and pollen germination studies were also conducted. Pollen viability was maximum in Pixie mandarin (92.81%) while least in Frost dancy tangerine (FDT) (16.27%). Pollen tube growth studies revealed non-significant difference as pollen tube travelled 9.16, 5.80 and 4.70 % of the gynoecia, in tangelos, mandarins and tangerine hybrids respectively. Kinnow generated the best value as the male parent with Honey mandarin and Orlando tangelo, while the performance with other hybrids was inconsistent as for as specific combining ability (SCA) was concerned. Although, Kinnow belongs to mandarins yet, great variability was found with Pixie mandarin for combining ability. Kinnow proved as a better pollinizer for all the experimental h...

Glutamic acid (GA) is an α-amino acid that is used by almost all living beings in the biosynthsis of proteins. Therefore, in the present study, we tried to investigate the effect of foliar application of glutamic acid (GA) on cucumber (Cucumis sativus L.) under altered salinity levels. Cucumber seedlings were grown in plastic pots under greenhouse conditions by applying four levels of salinity (0, 3 dS/m, 6 dS/m and 12 dS/m) and two levels of foliar applied GA (0, 10 mM). Salinity was induced by mixing the salt and soil before seed sowing; however, exogenous GA was applied when the vine length was reached up to maximum height. Morphological characters showed disruptive response under saline conditions especially in indigenous cultivar (local cucumber represented as V1). Enhanced activities of superoxide dismutase (0.29 u g-1 F...

An Early Responsive to Dehydration (ERD) 15 gene (SlERD15) was cloned from the cultivated tomato (Ailsa Craig) having open reading frame of 486 bp and an intron of 102 bp. SlERD15 encodes 162 amino acids in contrast to 156 amino acids of previously reported ERD15 (SGN-U214024). SlERD15 encoded protein has a conserved motif PAM2. SlERD15 transcript accumulation was higher in older leaves and tomato fruit at colour break stage than in other plant organs. Expression profile revealed increase in transcript level of SlERD15 on exposure of Ailsa Craig to dehydration (drought), salinity, ABA, ethylene, GA3 and salicylic acid. Messenger RNA level of SlERD15 was decreased initially followed by increase in response to heat and wounding stress. While, transient rise in mRNA level of SlERD15 was noticed in response to cold stress. The transcript accumulation d...
