Two crop growth experiments in the soil-based closed ecological facility, Laboratory Biosphere, were conducted from 2003 to 2004 with candidate space life support crops. Apogee wheat (Utah State University variety) was grown, planted at two densities, 400 and 800 seeds m-2. The lighting regime for the wheat crop was 16 h of light-8 h dark at a total light intensity of around 840 micromoles m-2 ...

This paper briefly reviews research on the causative agents of blackleg and soft rot diseases of potato, namely Pectobacterium and Dickeya species, and the disease syndrome, including epidemiological and aetiological aspects. It critically evaluates control methods used in practice based on the avoidance of the contamination of plants, in particular the use of seed testing programmes and the ap...

An experiment was conducted to identify the appropriate time of planting for red ant management and increase tuber yield potato at Agriculture Research Station (ARS), Jaubari, Ilam, Nepal (2900 masl) during 2020 2021 season. Seed potatoes were planted in 9 different plant dates that December 1, 15, January February March 15 April 1. The laid out Completely Randomized Block Design (RCBD) with th...

Sprouting regulation in potato tubers is important for improving commercial value and producing new plants. Camphor shows flexible inhibition of tuber sprouting and prolongs the storage period of potato, but its underlying mechanism remains unknown. The results of the present study suggest that camphor inhibition caused bud growth deformities and necrosis, but after moving to more ventilated co...

The seed potato cost is very important component in total production and account for 30 to 70% which varies depending on the country or region. Tuber size an factor decide requirement per unit area. Seed affects yield, graded marketable tuber yields. Standard of 25–125 g weight (30–55 mm) known as tubers India. Obtaining achieving higher potential cultivars. profile can be reduced expanded by a...

In order to evaluate the impact of crop residues (zero, 25 and 50%) and nitrogen (zero, 125 and 250 kg ha) on weed seed bank and potato yield, two-years research was conducted as a split plot arranged in randomized complete block design in Rozveh Agriculture Research Station, Freidan-Esfahan. Numbers of weed species in seed bank, aboveground, and both seed bank and aboveground were 1, 2 and...

Potato (Solanum tuberosum L.) varieties, viz. Kufri Lauvkar (early maturing), Gaurav and Jyoti (medium maturing) were examined during the years 2018–19 2019–20 for seed size tubers production with 3 dates of haulm killing, 70, 80, 90 days after planting under West-Central Indian conditions at ICAR-Central Research Institute, Regional Station Gwalior, Madhya Pradesh. Haulm killing 80 (15.05 t/ha...
