Res., 3(2): 240-244. Abstract Eleven tomato genotypes AVTO Germination percentage, days to first flowering, days to first fruiting, days to first fruit ripening, internode length, leaf length, leaf width, and stem diameter were studied during the experiment. Higher germination (91.3 %) war recorded in AVTO-1288. Early first flowering (51.7) and first fruit ripening (87.7) was observed in AVTO-1405 whereas early first fruiting (61.3) was recorded in AVTO-1409. The lengthy leaves (7.0 cm) and wider leaves (3.8 cm) were recorded for AVTO-1405, while bigger stem diameter (1.9) was recorded for AVTO-1456. These genotypes should be further studied for desired character and may be exploited in future breeding program.

Salinity stress is a barrier to crop production, quality yield, and sustainable agriculture. The ... more Salinity stress is a barrier to crop production, quality yield, and sustainable agriculture. The current study investigated the plant growth promotion, biochemical and molecular characterization of bacterial strain Enterobacter cloacae PM23 under salinity stress (i.e., 0, 300, 600, and 900 mM). E. cloacae PM23 showed tolerance of up to 3 M NaCl when subjected to salinity stress. Antibiotic-resistant Iturin C (ItuC) and bio-surfactant-producing genes (sfp and srfAA) were amplified in E. cloacae PM23, indicating its multi-stress resistance potential under biotic and abiotic stresses. Moreover, the upregulation of stress-related genes (APX and SOD) helped to mitigate salinity stress and improved plant growth. Inoculation of E. cloacae PM23 enhanced plant growth, biomass, and photosynthetic pigments under salinity stress. Bacterial strain E. cloacae PM23 showed distinctive salinity tolerance and plant growth-promoting traits such as indole-3-acetic acid (IAA), siderophore, ACC deaminase...

This proposed research study was conducted at the Ornamental Nursery Horticulture Department, The University of Agriculture Peshawar to investigate the response of foliar application of chitosan on vegetative growth and quality characteristics of tomato during the year 2016 using experimental design Complete Randomized Design (CRD) with one factor repeated three times. Tomato plants were sprayed with different chitosan concentration (0, 30, 60, 90, 120 mg/1000ml) with 25 days interval under plastic tunnel condition. The analysis of results showed significant effect of chitosan concentration on all growth and quality attributes of tomato. The results of foliar application of chitosan on different growth (number of leaves plant, number of branches plant and plant height) and quality traits of tomato (chlorophyll content, ,...

Foliar application of micronutrients and plant growth regulators (PGRs) is one of the strategies ... more Foliar application of micronutrients and plant growth regulators (PGRs) is one of the strategies of plant-feeding direct through leaves to allow rapid uptake irrespective of soil condition. This is the best way to enhance nutrient balance and its accumulation in the crops that, in turn, lead to improved crop yield and quality. This research studied the effect of boron (0, 25, 50, 75, and 100 ppm) and gibberellic acid (GA3; 0, 20, 40, and 60 ppm) on quality fruit production of pear. Fruit weight, yield (kg/tree), minimum fruit drop (%) and disease incidence (%) were significantly enhanced in fruit sprayed with 75 ppm boron while fruit firmness (kg/cm), total soluble solids (° Brix), fruit juice pH, ascorbic acid content, and minimum titratable acidity (%) significantly increased in pear fruit sprayed with 100 ppm boron. The highest contents of phenols, flavonoids, and antioxidants (%) were observed in pear fruit sprayed with 100 ppm of boron and 60 ppm of GA3. Maximum fruit firmness, total soluble solids (° Brix), fruit juice pH, ascorbic acid with minimum titratable acidity (%) were recorded in plants sprayed with 60 ppm GA3. Boron (100 ppm) and GA3 (60 ppm) could be applied at the fruit set stage to obtain the quality fruit production of pear.
