    The amount of crop yield reduction depends on such factors as crop growth, the salt content of the soil, climatic conditions, etc. In extreme cases where the concentration of salts in the root zone is very high, crop growth may be entirely prevented. To improve crop growth in such soils the excess salts must be removed from the root zone.   The study aimed at identifying the influence of different plant population density and fertilizer rates on three different maize varieties, it was carried out in two cropping seasons (/ and /) at Ibadan and Ikenne in South-western Nigeria. The experiment was a split-split-plot design with three replications. Maize variety (Swan 1-SR an open-pollinated, Obasuper a hybrid and Cited by: 4.

There is limited incentive in the private sector to create and distribute information publicly about crop management because of the necessity to control proprietary information. The generation of novel and timely crop management information therefore remains a critical outcome for publicly-funded agronomic research.

Crop management practices for the safe use of salt-affected soils and saline water primarily consists of growing suitable salt-tolerant crops, managing seedbeds, and grading fields to minimize local accumulation of salts, soil management, improving irrigation efficiency and soil, water, and salinity monitoring for assessing leaching and drainage requirements.

A field experiment was conducted in Assosa District of Influence of spacing on crop characteristics and yield book Ethiopia during cropping season to determine the effect of different inter row (20, 30, 40, 50cm) and intra row spacing (5, 10, 15cm) on growth parameters, yield components and yield of Desi chickpea.

The experimental design was randomized complete block design in factorial arrangement with three by: 1. During a field experiment was conducted at experimental area of Faculty of Agriculture under Lasbela University of Agriculture, Water and Marine Science, Uthal, Lasbela to evaluate the influence of various row spacing on the yield and yield components of Raya Anmol and Faisal Canola under coastal climatic conditions of by: 1.

Crop row spacing and time of planting can greatly influence the crop's competitive ability. Especially for soybeans, reduced row spacings have increased the ability of soybeans to provide additional competition with weeds, so that (under current production practices) soybeans may be more competitive than corn.

reason for the yield advantages realized as it takes several years for these soil characteristics to develop. • It should be noted that crop yield response to tillage could be widely variable and site-specific, as impacted by environmental factors, soil type and drainage, and.

When planting vegetables, spacing can be a confusing topic. So many different kinds of vegetables need different spacing; it’s hard to remember how much space goes between each plant. In order to make this easier, we have put together this handy plant spacing chart to help you.

To obtain high chia seed yields and seed qualities, a suitable crop management system needs to be developed for the given growing conditions in southwestern Germany. Field experiments were conducted at the experimental station Ihinger Hof in two consecutive years (, ).

Grimes, Timothy D. Phillips, Filippo Capezzone, Simone Graeff-Hönninger. Crop yield is defined by the interaction among plants, production environment and management. Sowing time, cultivar, plant spacing and density are management practices that influence production components, and thus soybean yield.

Hemp is one of the most important green (i.e., environmentally sustainable) fibers. Planting density, nitrogen (N), phosphorus (P) and potassium (K) significantly affect the yield of hemp fiber.

By optimizing the above main four cultivation factors is an important way to achieve sustainable development of high-fiber yield hemp crops. In this study, the effects of individual factors and factor Author: Gang Deng, Guanghui Du, Yang Yang, Yaning Bao, Feihu Liu.

Cultural weed control involves manipulating the crop-weed environment so that conditions are more favorable for crop plants than weeds. Crop rotation and crop competitiveness are important cultural control practices in winter wheat production. Crop Rotation. Crop rotation is an important component of integrated weed management.

Availability of water is main factor in sunflower productivity. Planting density also influence the yield of sunflower. An experiment was carried out at postgraduate research area of Department of Agronomy, University of Agriculture, Faisalabad during autumn to evaluate the effect of row spacing under reduced irrigation conditions on growth, yield and oil content of by: 4.

SPACING AND CUTTING CYCLE INFLUENCE ON SHORT ROTATION SILVER MAPLE YIELD Wayne A. Geyer, Research Forester, Kansas State University1 Field studies showed that silver maple trees grown at close spacings produced annual dry-weight-wood yields of 4 tons/acre, even after numerous coppice cuttings over an 8-year period.

characteristics influence this range slightly. If charcoal rot is evident or lodging is a potential threat, harvest without delay. Wind and storms have caused severe field losses of 22, 39 and, in a bad storm, 53 percent of the grain sorghum yield in experiments. The larger heads are most prone to lodge, should adverse weather occur before.

Significantly maximum seed cotton yield ( kg ha-1) was recorded when crop was sown at cm plant to plant spacing. However minimum yield ( kg ha-1) was obtained in case of 15 cm plant. Abstract.

A valuable additional approach is available through the breeding of crop ideotypes, plants with model characteristics known to influence photosynthesis, growth and (in cereals) grain production. Some instances of the successful use of model characters of this kind are by: Rice (Oryza species) is a unique annual cereal food crop growing under flooded condition up to m.a.s.l and pH Production of rice depends on several factors: climate and crop management.

is to link plant physiology and crop management. Crop yields are an essential aspect of every farmer’s day, impacting how profitable their farmland can be. Learning how to improve crop yields is key to successful farming, and access to new technologies and planting methods has given farmers an opportunity increase crop production – the key to maintaining the long term sustainability of their farm.
