The mineral contents in common bean seeds are influenced, in addition to genetic variation, by environmental crop conditions, especially by the soil type and chemical composition and by the genotype x environment interaction. This study was carried out to verify if the zinc and iron contents are affected by the crop growing period. Ten lines with high iron and zinc contents and ten with low con...

Conventional seedbed preparation for spring sown crops in Sweden includes 3±4 harrowings followed by sowing, but there is a great interest among farmers to reduce this tillage. Since the soil is normally at ®eld capacity after winter, the conventional system implies a major risk of soil compaction and the farmer has to wait for the soil to dry before seedbed preparation can be started. A new te...

This study was carried out during three successive seasons 2004/05, 2005/06 and 2006/07, to evaluate fifty F derived lines (from the F diallel cross), with three check varieties under two different irrigation regimes. 3 2 Twenty different lines were selected from the fifty F lines under each level of irrigation and evaluated under 3 the same conditions in the F and F generations. Also, the effe...

Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined with a high stocking density of cows, means this potentially leads to large amounts of urinary nitrogen (N) deposited on bare, wet soil, that in turn, could lead to high nitra...

In this study we investigated the perspective offered by coupling a simple vegetation growth model and ground-based remotely-sensed data for the monitoring of wheat production. A simple model was developed to simulate the time courses of green leaf area index (GLAI), dry aboveground phytomass (DAM) and grain yield (GY). A comprehensive sensitivity analysis has allowed addressing the problem of ...

The effects of irrigation and planting pattern on wheat in field conducted at Taian, northern China during 2011-12. The experiments consisted of two planting patterns (single and double rows) and two irrigation levels (0 and 180 mm) resulting in the same plant density (200 × 10 plant/ha). Each experiment plot was 3 m × 3 m in size and replicated thrice in split-plot design. During course of stu...

Vertisols occur extensively in centralIndiaand have high production potentials. Because of the high clay content (40-60% or more), high bulk density (1.5-1.8 Mg m-3) and related properties, these soils have high moisture storage capacity. Conversely, these soils become very hard when dry and very sticky when wet. Since last two decades, scientists, farmers and also the policy makers have be...

Purpose: to determine the most effective options for irrigation regimes, growth stimulation that meet requirements of resource-saving technology common beans cultivation under conditions Astrakhan region. Materials and methods. To study effect pre-sowing inoculation planting material (seeds) beans, as well a field experiment was set up. The object bean variety Rubin, admitted Nizhnevolzhsky Fie...

Drought during the overwintering period threatens emergence rate and restricts yield under “winter-seeded spring wheat” cultivated model in Hetao Plain Irrigation District Inner Mongolia. To address this issue, from 2017 to 2019, six treatments were set up field study rate, growth attributes, grain quality, its percentage of winter-seeded wheat. These (1) application water-retaining agents wint...
