A study was conducted in farmer's field through front line demonstrations during Kharif season of 2015 and 2016 in Ganjam district of Odisha to evaluate the short duration drought tolerant upland rice variety Sahabhagidhan. The results of demonstration showed that farmers could increase the productivity notably by switching over to improved variety Sahabhagidhan and adoption of improved production technology. From the front line demonstration, it was observed that rice variety Sahabhagidhan recorded higher grain yield (32.9q/ha) as compared to farmers practice Khandagiri (25.2q/ha). The increase in the demonstration yield over farmer's practices was 30 per cent with harvest index 47.4. The improved variety gave higher gross return of Rs. 50029 ha-1 with a benefit cost ratio of 1.46 and additional net return of Rs.9626 ha-1 as compared to local check.

A study was carried out to standardize nitrogen application at different stages of tuberose (Polianthes tuberosa L.) (cv. Double) for improving growth, flowering and vase life in a farmer’s field at Gunjanagar VDC, Chitwan, Nepal, during May to September, 2012. The experiment was laid out in randomized complete block design with 10 treatments of nitrogen in split doses and replicating thrice. The cut flower and vase life characteristics of tuberose were studied and the economics of production was also analysed. Significant difference was found between treatments of split doses of nitrogen in flowering and post-harvest characteristics of this flower. Three equal split doses of nitrogen, 33% N basal + 33% N at 30 days after planting + 33% N at 50 days after planting resulted in the earliest spike initiation (60 days) and the first flower opening (95.17 days). The same treatments recorded longest vase life (16.47 days). The longest (91.69 cm), heaviest (87.97g) and thickest (0.89 cm) spikes with longest rachis (38.77 cm) were produced by three equal split doses of nitrogen, 33% N basal + 33% N at 50 days after planting + 33% N at 70 days after planting. The same treatments produced maximum net income (NRs. 214,250/-) and benefit-cost (B:C) ratio (1.29) per hectare. Thus, three equal split doses of nitrogen, 33% N basal + 33% N at 50 days after planting + 33% N at 70 days after planting are appropriate for commercial cultivation of tuberose in Nepal.DOI: http://dx.doi.org/10.3126/njst.v15i1.12006  Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 23-30

The vast diversity of nematodes has adapted to endure in different trophic groups as free living and parasites of plants and animals. In search of potential entomopathogenic nematodes (EPNs), soil samples were collected from, the rhizosphere of Apple orchard in Darima, Nainital, Uttarakhand, India north-western Himalaya in August 2019. The whole experimental activity carried out at ICAR-Vivekanada Parvatiya Krishi Anusandhan Sansthan, Almora during 2019–2021. In present study, Pristionchus pacificus was isolated using Corcyra bait trap, identified based on morphological and molecular approaches, studied its host range, evaluated the phylogenetic tree of P. pacificus and isolated and characterized the nematode associated bacteria. The reproduction potential and frequency of emergence of P. pacificus differs significantly among the tested hosts on Corcyra, Spodoptera and Holotrichia larvae. The molecular diagnostics of associated bacteria based on 16S gene displayed the highest homology with Myroides marinus strain. The discovery of P. pacificus VLPP01 represents the first record from India and Himalayan region.
