The study pertaining to evaluation of different levels of potassium and zinc fertilizers on the growth and yield of wheat was conducted at Chakkanwali Reclamation Research Station District Gujranwala during Rabi Randomized complete block design with factorial arrangement used to lay out this experiment. Before sowing the seeds, the following nutrients were homogeneously incorporated. The Green Revolution, or Third Agricultural Revolution, is a set of research technology transfer initiatives occurring between and the late s, that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late s. The initiatives resulted in the adoption of new technologies, including high-yielding varieties (HYVs) of cereals.
A greenhouse study was conducted at the crop pavilion of the Department of Agronomy, Faculty of Agriculture, University of Ilorin, Nigeria to investigate the interactive effects of soil moisture content and fertilizer level on growth and achene (seed) yield of sunflower. Four irrigation amounts (, , and cm 3, equivalent to 25, 50, 75 and % of field capacity) and four. Lessons from Long Term Fertilizer Experiments 1.

It encompasses any type of soil fertilizer that contains potassium as one of its active ingredients. Corn and soybean grain K content can increase with increasing K rate in studies, but there is some recent evidence that grain K levels in both crops might be even lower than the “book values” used for years. Quadratic yield-response functions were used to derive economic and technical optimum rates of N-fertilizer applications. Based on the parameterized function and fertilizer-to-product price ratios observed for , we analyzed the difference between recommended fertilization and economic optimum application rates.

response of rice crop (super basmati) to different nitrogen levels. Article (PDF Available) in Journal of Animal and Plant Sciences 16(): January with Reads. If high yields and protein are sought, high levels of nitrogen fertilizer must be applied.
For Soft White Spring Wheat (SWSW) however, the optimum level of fertilizer application is up to the point of maximum yield response to nitrogen. Any excess application beyond this point will raise wheat protein significantly which is undesirable.
The time of N fertilizer application has an effect on yield of rain-fed crops. It is generally recommended to split the fertilizer application so that half is applied at sowing and the other half 20 to 45 days after sowing, depending on soil moisture availability and type of crop.
levels for cereal crops when recommended practices are employed; however, such benchmarks are best set locally within the appropriate cropping system, soil, climate and management contexts. Global temporal trends in NUE vary by region. For N, P and K, partial nutrient balance (ratio of nutrients removed by crop harvest to fertilizer.

Two significant advantages of surface-residue management are increased OM near the soil surface and enhanced nutrient cycling and retention. Experiment was conducted to determine the effect of different nitrogen levels on four bread wheat varieties (Triticum aestivum L.) viz.

Cucumbers prefer light textured soils that are well drained, high in organic matter and have a pH of 6 - Optimum water–fertilizer management in rainfed agriculture is an important factor in improving crop productivity and the ecological environment under fluctuating climate conditions, especially in Southwest China, where seasonal drought and waterlogging occur frequently.

RICE. The young crop should be cultivated in fertile lands. If this young crop (seedling) looks weak, then at least 10 days before its transfer to the rice fields (from the paddy fields), put g urea per marla. Conceptual diagram showing possible effects of fertilizer application to crops on SOC as defined by relationships between increasing fertilizer N application levels and (i) yield and crop residue production, (ii) change in yield per unit N input, and (iii) residual soil inorganic N.
Maximum yield of the crop is obtained at the optimum N by: Sunflower (Helianthus annuus L.) is the leading non-conventional oilseed crop in Pakistan.
Nitrogen fertilizer can affect plant growth and productivity by changing canopy size which has an effect on the radiation use efficiency (RUE) of the crop.

Singh and Mohanty () reported that N and K at and 80 kg ha-1 resulted in the tallest plant. Leaf length (cm): A careful observation of the results revealed that both varieties and fertilizer levels as well as their interaction were highly significant.

Crops vary not only in their tolerance to salinity but also in their water requirements, optimum growth season, rooting depth and moisture extraction pattern and cultural requirements.
Thus, in the absence of proper water and soil management practices, salinity of the soil may be affected differentially under various crop rotations. Sepaskhah and Hosseini () indicated that there was substantial increase in yields of crops including wheat with the application of N.
Contrary to this, it has been reported that the yield response to N fertilizer application was not linear (Cossey et al., ), resulting in very low nitrogen use efficiency (NUE). Soils and irrigation waters in Saudi Arabia are naturally rich in potassium (K).
In spite of this, farmers and large-scale agricultural companies usually add K fertilizers to various crops without soil and water testing and whether or not the crop requires high amount of K.
The objective of these experiments was to study the response of fresh tuber yield, specific gravity, and frying quality Cited by:.

VERMICOMPOSTING OF KITCHEN WASTE Material and Methods Results and Discussion .The response of N fertilizer with various rates on head diameter was higher with increasing trend of N fertilizer. The maximum head diameter ( cm) was produced by N 4 treatment followed by N 5 that produced cm head diameter and statistically minimum head diameter ( cm) was recorded in plot that was not fertilized with N (N 1).
The crop was thinned out at leaf stage in order to maintain the optimum plant population. All other agronomic practices were kept normal and uniform for all treatments except harvesting times. The crop was harvested first time on Septem and kept in the respective plots for sun drying.
