Growth and grain yield of irrigated barley cultivars (Valfajr, Binam and Raihaneh) was investigated at 4 sowing dates (6, 22 Oct. and 14, 20 Nov.) in Karaj region. The effect of sowing date, genotype and their interaction on grain yield were statistically significant. Early and late sowing enhanced cold damage. However, the damage was more in late sowings. It was estimated that the optimum sowi...
Determination of optimum sowing date plays an important role in crop management and achieving the higher yield. To study the effectof sowing date on seed yield of canola cultivars, a filed experiment was carried out as strip split plot block arrangement in randomized completed block design with three replications in 2017-18 and 2018-19 cropping seasons at Safiabad Agricultural and Natural Resou...
In this research, the impact of a carbon sequestration project, in the Hossein Abad Plain in Southern Khorasan Province of Iran, on the status of water and wind erosion was evaluated. The study area has a harsh climatic condition with low annual precipitation and is prone to well-known 120-day winds in summer. Since 2005, various soil conservation treatments (plantations, over-sowing, plantatio...
Despite extensive study of pollination and plant reproduction on the one hand, and of plant demography on the other, we know remarkably little about links between seed production in successive generations, and hence about long-term population consequences of variation in pollination success. We bridged this "generation gap" in Ipomopsis aggregata, a long-lived semelparous wildflower that is pol...
Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for...
Influence of different irrigation methods on growth and yield of summer greengram (Vigna radiata L.)
A field experiment was conducted at Wetland farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during summer 2022 to study the effect growth and yield parameters greengram under different irrigation methods. The laid out in randomized complete block design having seven treatments replicated thrice. treatment are T1: Check basin method (Line sowing), T2: (Broadcasting),...
To evaluate the effect of autumn sowing date on seed yield of sunflower cultivars, a field experiment was carried out as strip plot arrangement in randomized complete block design with three replications in safiabad agricultural and natural resources research and education center of Dezful, Iran during two growing seasons (201718 and 2018-19). Seven sowing dates (6th Sep., 23rd Sep., 7th Oct., ...
Effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, N-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at Nuclear Institute for Food and Agriculture, Peshawar, Pakistan. Poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...
Aspen produces large numbers of seeds, even though it mainly reproduces asexually with root suckers. The aim of this study was to find out how different moisture conditions affect emergence and survival of Populus tremula L. seedlings. This was studied with a sowing experiment (totally randomized factorial design). There were altogether 10 blocks, each containing 16 microsites and three treatme...
