that might compete with the cash crop (Fontanétti ). In organic farming, legumes are used for intercropping and the formation of mulch suited to the no-tillage system. The present study aimed at evaluating the agronomic traits and yield of maize, using different cover crops and two organic no-tillage systems. MATERIAL AND METHODSAuthor: Lamara Freitas Brito, João Carlos Cardoso Galvão, Jeferson Giehl, Silvane de Almeida Campos, Stelian. ability for grain yield and other agronomic traits in maize (Zea mays L.) at two years and , using RCBD with three replications. Results of combined ANOVA revealed that year effect was significant for all the parameters. Based on diallel cross analysis according to Griffing method 2, the general combining ability (GCA).

Abstract. Field trials were conducted on two soil types for seven years (–) to investigate grain yield response of maize to crop residue application as influenced by varying rates of applied and residual N and P by: Field studies were conducted at the Teaching and Research farm of the Cross River University of Technology, Obubra Campus, Nigeria, during the and cropping seasons to determine the agronomic performance of maize under different rates of poultry manure (PM) application. Ten rates of PM treatments consisting of 0, 4, 6, 8, 10, 12, 14, 16, 18, and 20 t/ha were used in this .

Intercropping as a simultaneous growing of two or more crops in the same field is a cropping system that has long been used for a long time especially in the tropics to increase productivity and sustainability through maximum utilization of land, labor and growth resources, hence the study was conducted to evaluate growth and yield effect of maize variety intercropped with two Author: Adeyeye A.S, Akanbi, Olalekan, K.K Lamidi, Othman, and Ishaku, Sift Desk. This research is focused to find optimal crop density to enhance maize forage and dry matter yield. We examined the effect of three crop densities (51, plants -ha-1, 59, plants ha 1 plants ha-) on the plant height (PH), stem diameter (SD), number of leaves per plant NL), forage yield hectare(-1 (FY).

Maize Yield and Components as Influenced by Environment and Agronomic Management Jeremy Jon Milander, M.S. University of Nebraska, Advisor: Steve Mason Yield component analysis research on dent maize and waxy maize (Zea mays L.) as related to crop management is limited in Europe and the United States.

Maize and Grace - Africa's Encounter with New World Crop By James C. McCann 2. Corn Crop Production - Growth, Fertilization and Yield Edited by Arn T. Danforth The first book: Maize and Grace is a paperback and reasonably priced at $Cited by:   Knowledge of genetic diversity within crop species and the nature of their breeding systems are critical for crop improvement.

These determine the appropriate species specific breeding methodologies to deploy. Genetic diversity analysis is an ongoing process in the breeding programmes of ‘major crops’, which is used to direct or re-direct breeding objectives Cited by: 7.

Introduction. Agriculture is an information-intensive industry from an essential point of view. Many factors such as sowing date, soil type, fertilizer, location, hybrid, season duration, etc.

influence yield and yield components of a grain crop and they are well needed by agricultural ing the agricultural technologies of traits related to the control of crop grain yield Cited by: The HHH is the most intensively cultivated region in China.

The average crop yield increase between and was from to kg ha −1 for wheat and to kg ha −1 for maize. The present crop yields are and times the national average yield of wheat and maize in China, respectively.

Maize (Zea mays L.) is an important staple food crop and provides bulk of raw materials for the livestock and many agro-allied industries in the world (Bello et al., ).

Despite its importance, maize grain yield is severely constrained by drought. Drought occurs during or shortly before flowering, the estimated yield loss may be in theFile Size: KB.

Grain yield and number of pods per plant decreased in intercrop with soybean variety Samsoy-2 having the highest number of pods per plant and grain yield. The result on maize indicated that maize planted sole was significantly (P.

At each density, the yield of intercrop maize did not differ from those of the sole maize. However, intercrop bean yield significantly increased with a rise in bean density. The seed yields of beans were kg ha-1, kg ha-1 and kg ha-1 from the lowest to the highest density. Although maize contributed more than 80% of the mixture yield.

ESTIMATING MAIZE GRAIN YIELD FROM CROP BIOPHYSICAL PARAMETERS USING REMOTE SENSING Noemi Guindin-Garcia, Ph.D. University of Nebraska, Adviser: Timothy J.

Arkebauer The overall objective of this investigation was to develop a robust technique to predict maize (Zea mays. L.) grain yield that could be applied at a regional level using. Yield definitions Crop yield ‘Crop yield’ is the weight of grain or other economic product, at some agreed standard moisture content, per unit of land area harvested per crop (usually metric tons per hectare 1, or here abbreviated to t/ha).

Standard moisture content varies between crops but is 8–16% in by: Rational crop community structure plays an important role in maximizing the intercropping yield advantage. Effects of increasing maize densities in maize (Zea mays L.)/peanut (Arachis hypogaea L.) intercropping on yields and other agronomic traits, and the community stability of productivity were conducted across three different experimental sites.

There were significant Cited by: 1. results indicated that the agronomic innovation packages could improve maize yield by 1 t ha-1 to t ha-1 in the studied countries. The magnitude of the yield improvement is country and package specific.

The largest maize yield improvements across the packages were obtained by. In this study we evaluated maize (Zea mays L.) yield, N application rates, N-use efficiency (partial factor productivity), net economic gains (defined as the difference between economic return of maize and N fertilizer cost), and technology adoption rate by farmers in a county who were assigned to TP and OTP groups vs.

those following Cited by: An experimental study was conducted to evaluate the relationship between yield and its components in maize through correlation studies. Yield is the foremost consideration in the breeding of any crop. Since the yield depends upon many yield contributing characters, it becomes essential to study the contribution of each character to the Size: 1MB.

Thus, the value of multiple location varietyFile Size: KB. Studies have shown that that about 85% of maize farmers in Western Kenya plant local varieties with about 80% using own farm-saved seeds.

The production system is characterized by late harvesting, heavy striga infestation, use of local varieties, and low-soil fertility. The objective of this study was to test an on-farm seed production system which would help improve yield and Cited by: The chapter begins with an analysis of the interaction between genetic-engineering technology and crop yield.

That is followed by an examination of the agronomic effects of insect-resistant (IR) crops, specifically in terms of crop yield, insecticide use, secondary insect-pest populations, and the evolution of resistance to the GE trait in targeted insect populations.

A major strategy of IITA’s Maize Improvement Program is to breed cultivars that are Striga resistant and drought- and low-N tolerant to increase and stabilize maize yield production in the subregion. Two approaches have been adopted for drought tolerance.

The first is to breed for extra-early maturing cultivars that are drought escaping. Growth parameters: Data pertaining to the plant height revealed that combined application of compost and inorganic fertilizer during significantly influenced plant height of maize ().Duringthe maximum plant height ( cm) was recorded from 5 t ha-1 compost+50 kg urea ha-1 with urea whereas; in compost at 10 t ha-1 +50 kg urea ha-1 gave the tallest .Kuruvila Varughese and M.
