    Lastly, your tillage system could theoretically influence irrigation rates and frequency by influencing how quickly the cotton crop may reach the point of yield-reducing stress. Split Weekly Rates The water requirements listed in Figure 1 are total weekly water rates, including rainfall, and should be divided into two or more irrigations. On the other hand, applying irrigation too late can result in delayed harvest, increased pest management cost, and no yield increase, not to mention the costs of the irrigation itself. The COTMAN program has proven useful for making end-of-season decisions, and a study was carried out in the Mid-South to see if the COTMAN approach could be.

    Goals / Objectives (1) Evaluate the adaptation of new commercial cotton varieties to the field production environments of Tennessee in terms of yield potential, earliness of maturity, fiber quality, and yield stability; (2) Determine the physiological efficiency, economic potential and agronomic components of alternative cropping systems, such as ultra-narrow-row (UNR) cotton systems. irrigation during the growing season may eliminate crop water stress, but it will also lessen irrigation efficiency and yield response to other management practices, such as fertilization, planting date, popula-tion and weed control. Inadequate irrigation, on the other hand, results in crop water stress and less yield.

    ANSWER 2: Irrigation schedule for groundnuts based on months of peak irrigation water need. As can be seen from the table above, the months of peak Irrigation water need are September and October. In this example the irrigation schedule will be based on these two months. Step 1: Estimate the net and gross depth (d) in mm of the Irrigation. The irrigation frequency had a clear-cut effect on total dry matter weight and grain yield was dependent on the quality of the irrigated water. The raised bed with furrow irrigation system produced the highest harvest index for all of the levels of water quality and the highest water use efficiencies were observed for good-quality water.

The growth and yield of cotton cultivars may be influenced by irrigation. The date of last irrigation is critical in determining crop earliness. Cotton grown in the Mississippi River Delta of the mid‐South should be harvested in early October to avoid fall rains, which may reduce yield and lower fiber by: 2.

There have been conflicting results reported about the effect on cotton (Gossypium spp.) lint yield of altering planting and irrigation termination (IT) objectives of this study were to identify a planting window (PW), on a heat unit (HU) basis, and IT timing, as a function of crop growth stage, for optimum yield potential of Upland (G.

hirsutum L.) and American Pima (G. babadense L Cited by: Optimization of cotton irrigation termination (IT) can lead to more efficient utilization and conservation of limited water resources in many cotton production areas across the U.S.

This study evaluated the effects of three IT timings on yield, fiber quality, and irrigation requirements of irrigated cotton in southwest Oklahoma during three growing by: 5. The effects of variable irrigation termination (IT) dates on cotton yield, fiber quality and irrigation requirement were investigated in a field experiment i n southwest Oklahoma dur ing three.

Our objective was to evaluate over a 4-year period three irrigation termination thermal times corresponding to cumulative daily heat units (∑HU) of °C, °C and °C from crop emergence, and three levels of irrigation (, and mm/d) on cotton lint yield and fiber quality. Abstract | Cotton is a life line of Pakistan’s economy.

Drought stress is the major ecological factor that negatively impacts cotton yield and quality. A field experiment was conducted in at Cotton Research Station, Dera Ismail Khan, Pakistan to evaluate the effects of four moisture regimes on yield and fiber characteristics of two cotton genotypes.

Our objective was to determine the effects of irrigation regime and plant density on the growth, yield, yield components and fiber traits of cotton under field conditions, with a focus on cotton yield, fiber quality and water use efficiency as affected by plant density under deficit irrigation.

Materials and methods   Research highlights As a result of 4-year study that seed cotton yield was significantly affected by deficit irrigation. Evapotranspiration ranged from to mm in full irrigation and from to mm in the severe water stress treatment.

The highest seed cotton yield ( kg ha −1) was obtained from the I treatment with an average of mm irrigation water. It was concluded that. Irrigation protects the crop’s yield potential – being short an inch of water at the wrong time can easily result in the loss of 75 pounds of seed and 50 pounds of fiber.

Cotton is a life line of Pakistan’s economy. Drought stress is the major ecological factor that negatively impacts cotton yield and quality.

A field experiment was conducted in at Cotton Research Station, Dera Ismail Khan, Pakistan to evaluate the effects of four moisture regimes on yield and fiber characteristics of two cotton genotypes. Irrigation frequency also has a significant influence on growth and yield of wheat (Khajanij and Swivedi, ).

But in Bangladesh most of the farmers are not in a position to provide irrigation in different critical stages of wheat production because of the inadequate facility of irrigation devices and irrigation.

Irrigation water quality can be evaluated based on electrical conductivity (Table 1). There are two main issues related to salinity: short term, i.e., effect of water electrical conductivity on a particular crop and long term, namely, soil salinization.

There is abundant biodiversity in crop tolerance to salinity stresses (Tables 2 and 3). However, the impact of deficit irrigation on crop yield can be insignificant where the water stress is applied to the crop during specific growth stages that are less sensitive to moisture deficiency.

The two series of yield response factors, k y, showed wide ranges of variation of this parameter: The drip irrigation and 6 day irrigation interval gave better results ( kg ha-1) than the sprinkle irrigation method and 6 day irrigation interval ( kg ha-1) ().This resulted from that since the period of irrigation was longer in drip irrigation method, the plants were able to uptake more plant nutrients and water regularly.

Also, the insufficient irrigation due to surface flow in. The dependence of Acala upon a heavy set of late season blooms did not allow an early machine harvest without sacrificing yield and damaging the fiber.

Earliness, as defined in this program, was to be measured by the earliest date in the fall that cotton could be harvested by machines efficiently.3.

How does irrigation water cycle through an agricultural system? 4. How does water stress negatively affect crop development and yield?

A. The Role of Irrigation Water in Agriculture Systems 1. Sustains soil biological and chemical activity and mineralization during dry periods: In.Timing in regards to irrigation termination is no exception, and it (along with the amount of moisture) can affect yield, quality, and production efficiencies, for better or for worse.

Irrigation termination in cotton production is calculated by several factors including: Developmental stage; Soil type (and holding capacity) Geography.
