RÉSUMÉ
Aims: The current study was designed to investigate the nature and extent of heterosis for marketable fruit output, quality attributes, and resistance to tomato leaf curl virus.Study Design: Statistical Randomized Block Design.Place and Duration of Study: The current study was conducted in Horticulture Research Field at Sam Higginbottom University of Agriculture Technology and Sciences at Prayagraj U.P. India during Rabi, 2016–17.Methodology: The experimental included three testers and thirteen lines During Rabi, 2016–17, out of these, ten lines (female parents) were crossed with every three testers (male parents). The resulting 30 F1s were assessed for yield, fruit quality, and leaf curl virus resistance. To gather data, five plants from each replication were randomly tagged in each entry and analysis of variance was performed. Heterosis over better parent (BP) was calculated by treating each feature using the approach proposed by Hayes et al. [1]. The studied data were statically analyzed using the Indostat software Hyderabad program.Results: The standard heterosis for fruit yield ranged from -67.19 to 29.70% Check (Kashi Abhiman). Five crosses viz., Arka Abha x Kashi Aman, Arka Abha x Kashi Vishesh, Pant T-7 x Kashi Vishesh, S-22 x H-88-78-5 and Pant T-7 x Kashi Aman were exhibited sufficient amount of significant and positive heterosis for fruit yield over standard check. The hybrids Azad T-5 x Kashi Aman and Pant T-7 x Kashi Aman exhibited low incidence with negative heterosis for the ToLCV incidence and severity.Conclusion: Commercialization of hybrid vigor in tomato (Solanum lycopersium L.) has gained prominence due to various advantages of hybrids over pure line varieties, including higher marketable fruit output, component characteristics, and resilience to biotic and abiotic stresses. According to data presented in the study it is concluded that hybrid vigour can obtain by crossing of parents having desirable characters in tomato.
RÉSUMÉ
Aims: The production of cost of wheat is higher in farmers practice than the zero tillage sown of wheat due to non-adoption of recommended resource conservation technology, high-yielding varieties and advanced technologies by the farming community in the eastern plains of Uttar Pradesh. To replace this anomalous, we conducted 204 front-line demonstrations (FLDs) at farmers' fields in various adopted villages by Krishi Vigyan Kendra, Deoria.Place and Duration of Study: The study was carried out by the Krishi Vigyan Kendra, Malhana, Deoria, under the Indian Institute of Vegetable Research, Varanasi, UP.Methodology: Prior findings were examined to identify any gaps and to enlist everyone's assistance in disseminating such a technology of global relevance. In the eight years from 2011–12 to 2018–19, a total of 204 FLDs were carried out at the 230 farmer’s fields in the 32 villages where wheat was sown by zero tillage.Result: Rice-wheat cropping systems are the most often used agricultural method in Uttar Pradesh, India's hot, sub-humid (wet) eco-region. It provides farmers and agricultural labourers with a source of subsistence and revenue and is a crucial aspect of the region's infrastructure for food safety. In order to attain sustainable yield, it is always thought necessary to employ other alternatives of conserving essential inputs by adopting resources conservative techniques (RCT), such as zero tillage and broad bed furrow (BBF). According to the economic analysis of the data presented in the current study, zero tillage wheat farming is the most cost-effective and appealing alternative for the agricultural community of eastern Uttar Pradesh. When compared to the broadcasting method, the zero tillage technique yielded a higher return and a lower cost of cultivation per acre. Finally, the use of this strategy raises farmers' net returns, improves their social standing, living conditions, livelihood, and ultimately reduces poverty in the farming community.Conclusions: The new approach lowers production costs while producing equivalent wheat yields to other methods, which leads to higher net returns. Farmers in the area have begun to appreciate the technology's reduced tillage costs. Rice-wheat is the prevalent farming system practiced by the majority of farmers in the region. In the future, the prospect of extending the method to sow wheat after other crops should be investigated.
