“…Maximum fresh leaf weight was recorded in genotype KGT-1 (12.10 g) while minimum was recorded in the genotype, Ballmoral (8.07 g).These results were in conformity with these reported by Kumar et al [ ). The results are in line with the earlier findings of Son and Oh [7] , Dolma and Gupta [8] , Chatterjee [9]. The main focus of cultivating the crop is to have maximum yield per plant for better returns.…”

Lettuce is one of the major leafy vegetables used in salads, soups and occasionally lightly cooked. Leaf lettuce has garnered a central role in human nutrition, as it combines pleasing organoleptic properties with a rich content of nutraceutical compounds. Leaf lettuce can bring about a diversification in the tomato/bell pepper production system in the summer season. The cultivation of lettuce has already started picking up in Himachal Pradesh in summers. The produce from hilly areas are available at time when these cannot be grown in the plains due to high temperature, thus bringing lucrative returns to the growers. Twenty two diverse genotypes of lettuce were evaluated in Randomized Complete Block Design (RCBD) with three replications at KVK, Kandaghat, including standard check cultivar, Solan Kriti, to ascertain the extent of variability. The observations were recorded on various morphological and horticultural traits in leaf lettuce. On the basis of studies, it was concluded that genotypes viz., KGT-1, Lettuce C1, KGT-5 and LS-2 Selection-3, performed better in terms of yield and other horticultural traits over the standard check, Solan Kriti. So, these genotypes offer an ample scope for their release in the mid hill conditions of Himachal Pradesh after multilocational testing.

“…in a Mediterranean soil fertilized with an organic compost. Chatterjee (2015), testing different sources of nutrients on lettuce in the Hymalaian region, observed that plant yield was affected by the treatment with 10 Mg ha -1 manure mixed with 2.5 Mg ha -1 earthworm compost inoculated with a phosphate-solubilizing bacteria, which lead to the best results for leaf fresh weight.…”

The objective of this work was to evaluate the effect of a microbial fertilizer, produced from phosphate and potassic rocks and earthworm compost, as an alternative to conventional fertilizers, on lettuce (Lactuca sativa) nutrients and soil attributes. The experiment was conducted in consecutive cycles (30 and 60 days) in a soil from the Lorca region, in the municipality of Murcia, Spain. The fertilization treatments were: conventional fertilizer, 100% of the recommended rate (RR); microbial fertilizer, 50% of the RR (5 Mg ha-1); microbial fertilizer, 100% of the RR (10 Mg ha-1); microbial fertilizer, 150% of the RR (15 Mg ha-1); and control, without N-P2O5-K2O fertilization. The microbial fertilizers applied at 100 and 150% of the RR showed significant and positive effects, as well as the best results for plant characteristics. The microbial fertilizer increased total N and available P and K compared with the conventional fertilizer. A residual effect was observed in the successive cycle. The effectiveness of the microbial fertilizer shows it is a viable alternative to conventional fertilizers, with positive effects on plant productivity and soil attributes.

“…A significant contribution of Azotobacter and vermicompost on lettuce yield was reported by Chatterjee (2015). According to Muymas et al (2015), no significant differences in fresh weight and dry weight were observed between the control and lettuces treated with Bacillus licheniformis.…”

Plant biostimulants can enhance crop nutrition status, stress tolerance, yield and quality in environment-friendly manner. The aim of this study was to determine the effect of an algae and bacteria preparations on the yield and nutritional parameters of leaf and romaine lettuce cultivated for spring and summer crop. The application of a combined biostimulant consisting of plant growth-promoting bacteria (Bacillus licheniformis, Bacillus megatherium, Azotobacter sp., Azospirillum sp., and Herbaspirillum sp.) and fresh water algae (Chlorella vulgaris) was done by watering the lettuce every 14 days, and a determination of the fresh weight, total antioxidant capacity, and total carotenoids content was performed. The result revealed that the application of bacterial-algal preparation significantly affected the plant weight of both romaine and leaf lettuce in spring and summer seasons. The highest increase in the weight of romaine lettuce reached 18.9% in the spring crop, while in the case of leaf lettuce, biostimulant treatment led to a 22.7% higher weight in the summer crop. Total antioxidant capacity and total carotenoids content showed increased values in the summer crop of romaine lettuce, while for the leaf lettuce there were no differences between treatments. Therefore, the positive effect of bacterial-algal treatment on lettuce yield, total antioxidant capacity and total carotenoids confirm that it could be applied for improving romaine lettuce yield quality and quantity, especially in stress, summer conditions.
