dc.description.abstractABSTRACT Tomato (Solanum lycopersicum L.) is one of the most popular solanaceous vegetable crop grown worldwide. The present investigation entitled “Standardisation of agro-techniques for tomato production under protected conditions” was carried out with 15 hybrids to identify the superior planting material and standardise ecofriendly growing media with optimum fertigation level in the naturally ventilated greenhouses. Analysis of variance showed highly significant variation among hybrids for all the traits studied. US-285 was earliest to reach the first flowering (29.33 days) and marketable maturity (83.67 days). The hybrid Amisha recorded maximum values for number of flower clusters per plant (13.17), number of flowers per cluster (6.59), number of fruits per cluster (5.69), number of fruits per plant (57.00) and lycopene content (3.17). Naveen 2K+ recorded maximum fruit weight (74.17g), fruit yield per plant (3.81 kg), 15.24 kg/m2, 127.00 t/ha, harvest duration (54.67 days) and total soluble solids (4.93 0B). Rakshak recorded maximum fruit set (90.26 %), pericarp thickness (6.71mm) and shelf life (15.33 days). Maximum titrable acidity was recorded in Sartaj (0.82%) and highest ascorbic acid recorded in SH-7711 (24.39 mg/100g). For standardising ecofriendly growing media with optimum fertigation level, the combination of soil less M3 (Vermicompost:sand; 2:1) level of growing media alongwith Azotobacter and F3 (300:300:300 kg NPK/ha) level of fertigation (M3B1F3) had significant positive effect on number of flower clusters per plant, number of flowers per cluster, number of fruits per cluster, number of fruits per plant, average fruit weight (g), fruit yield, harvest duration, total soluble solids, pericarp thickness, lycopene content, available NK after harvest and higher cost:benefit ratio. On the basis of present findings the hybrids Naveen 2K+, Amisha and Rakshak can be recommended for tomato production under protected conditions in mid hill region of Himachal Pradesh in a soil less growing media composed of vermicompost and sand (2:1) alongwith seedling treatment of Azotobacter with a fertigation level of 300kg NPK/ha twice a week.en_US
