Effect of Different Environment and their Interactions on Growth and Yield of Tomato (Solanum lycopersicum L.) Cultivars

Abstract

during winter season of 2016-17 to study performance in and outside of poly-house to find out the most suitable and best cultivar, environment and interactions for growth, yield and quality of tomato fruits. The experiment was laid out in factorial randomized block design (R.B.D.) with three replications. Each replication consisted of eight treatment combinations viz., two tomato cultivars i.e., Pant Poly-house Tomato-2 (V1) and Pant Poly-house Hybrid Tomato -1 (V2), four environments (viz., E4-poly-house + spray of 2, 4-D), E3 (open + spray of 2, 4-D ), E2 (poly-house without spray) and E1 (open field without spray). Foliar spray of 2, 4-D @ 5 ppm concentration was applied as whole plant spray at 30, 45 and 60 days after transplanting of tomato seedlings. Results of investigation revealed that the cultivar V1 produced highest fruit yield which was 12.13% higher over V2. Among the environmental treatments, E4 produced 66.39, 78.64 271.39% higher fruit yield over treatment E3, E2, E1, respectively. Among the interactions, treatment V1E4 performed better for 10 characters whereas, V2E4 & V2E3 were better for 3 characters, and treatment V1E2 only for one character as compared to rest of the interactions. The treatment V1E4 gave 37.75% higher fruit yield than V2E4 and 84.44% over treatment V2E3 and 119.67% over V1E2.On the other hand, V2E4 produced 42.09% higher over V2E2 and 266.52% higher fruit yield over V2E1.Treatment V2E4 gave 33.89% higher over V2E3.

Innovative Application of Onion Extract to Improve the Quality of Tomato Fruit

“…The application of ZPT GA can also increase tomato germination in unfavorable conditions (Martins et al, 2018) (Martins et al 2018;Pramanik et al 2018;Shohat et al 2021;Ogugua et al 2022). Increased productivity of tomatoes given the ZPT GA3 was also reported in tomatoes grown in Bangladesh (Rahman et al, 2015), India (Kumar et al 2018;Jakhar et al 2018), and Nepal (Jha et al, 2022). ZPTs such as cytokines, brassinosteroids, and gibberellins can also be used to induce parthenocarpy, producing few or no seeds (Raja and Rani 2021;Sharif et al 2022).…”

A tomato NAC transcription factor, SlNAP1, directly regulates gibberellin-dependent fruit ripening

“…Hence, numerous studies have investigated the effects of GA on seed development and fruit growth [ 27 ]. It has been demonstrated that the utilization of GA can improve the firmness of tomato fruits by augmenting the concentrations of ascorbic acid, soluble solids, and fruit weight [ 28 , 29 ]. Research has shown that the suppression of the levels of GA through overexpression of the GA catabolism gene SlGA2ox1 in tomato fruit tissues may result in early ripening, suggesting a negative role of GAs in the tomato FR process [ 30 ].…”

Effect of Bio-Stimulant (Plant Probiotics) on Growth, Yield and Microbial Activity of Chickpea (Cicer arietinum L.) Grown in Vertisol of Chhattisgarh

“…Bio-fertilization, sense of root development, resistance to established stressors, and rhizoremediation are a few examples of direct impacts on plant development advancement [11,12,13]. Enhancing plant enzymatic mobility and managing plant microorganisms may indirectly promote plant development [14] Furthermore, bio-stimulatory compounds are known to be a successful way to repair semi-arid areas and damaged ecosystems by boosting microbial activity and improving soil biology [15,16,17,18].…”
