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 ...

An experiment was conducted during 2017–18 in the aeroponic unit of ICAR-Central Potato Research Institute inShimla, Himachal Pradesh, to evaluate 3 potato (Solanum tuberosum L.) cultivar’s, viz. Kufri Mohan, Lauvkarand Himalini growth and production behaviour under 2 different planting periods spaced 10 days apart duringthe autumnal season. The yield per plant total number mini-tubers were sho...

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...

Abstract To arrange a system of virus-free potato seed production in the Sakhalin region, series studies undertaken to come up with method towards material cultivation film-gauze greenhouses. At initial stage, key agrotechnical methods were developed for growing test-tube microplants, including optimal planting plans – 70×15 cm (the highest yield derived from standard mini-tuber fraction pcs/m ...

Micropropagation of potato in vitro by periodic cutting plants and passaging them to new nutrient media is the most common approach obtaining large volumes planting material mini-tuber production systems. The article summarizes research data on effect gibberellic acid, auxins, cytokinins rate plant growth internode formation microplants . According results published scientific literature, great...

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...
