A field experiment was conducted to study the response of wheat and rice to potassium during 2004-05. The basal dose of N at 120 kg, P2O5 at 90 kg ha -1 was applied with K levels to both wheat and rice crops. Wheat variety Naseer 2000 and rice variety IRRI 6 were used in the study. The experiment was carried out in R.C.B design with three replications. Potassium application significantly increa...

The present study was based on the hypothesis that muriate of potash is a cheaper and rich source of potassium, but adversely affects the crops yield due to high Cl content. For this reason both column and field experiments were conducted to study the effect of potassium rates and sources on the availability of Cl, SO4 and K to maize crop growing on Haripur and Ghazi soils during 2004. In colum...

Soil salinity is one of major deleterious abiotic stress limiting the yield wheat crop. Plant growth produce severely affected by various biotic and environmental metabolic processes. Application Potash fertilizer can reduce harmful effects saline increase crop yield. This research was carried out to evaluate detrimental on suggest appropriate dose potash achieve optimum production under condit...

Aim: Many countries import potassic fertilizers due to dearth of K-mineral deposits. Therefore processes to obtain K-nutrient sources from sea bittern were developed by our Institute. The present investigation evaluated the fertilizer potential of three different sea bittern-derived (SBD) potassium forms developed viz., potassium schoenite, potassium nitrate and potassium ammonium sulfate on ma...

It is in this connection that it becomes very difficult at times for the agricultural scientist and practical agriculturist to meet on common ground, for very often a popular version of scientific reasoning may appear ambiguous, and in this case it would appear better to sacrifice the facile version (since the layman can always get an interpreter to explain if he is sufficiently interested) tha...

The present study was undertaken to develop potassium management recommendations that maximize yield and post harvest quality of tomato. Studies were conducted at Faculty of Agriculture, Gomal University, Dera Ismail Khan, KPK, Pakistan during 2008-2009. A pot experiment was designed, which included six potassium fertilizer treatments (75, 150, 225, 300, 375, 450 Kg K2O ha ) with basal doses of...

I1 plots had higher germination (5.61%), millable canes (9.09%), brix (5.19%), yield (0.6%) and CCS (t/ha) (2.35 4.37% at 10th 12th months), respectively. K3 reported significantly performance as compared to K1 K2 treatments while being par with the K4 treatment. Benefits were be highest treatment under water stressed conditions. Hence, 80 kg K2O/ha potash deficient soils prove a better option ...

The objective of this study was to evaluate the effect an early application potassium (K) fertilizer on pearl millet (Pennisetum glaucum L.) grown during fall/winter performance maize (Zea mays silage in succession. Using a randomized block design, harvest, plots were composed and six doses K (0, 30, 60, 90, 120 150 kg K2O ha-1) as muriate potash (57% K2O) addition fallow. In summer cultivation...

The direct available method for phosphorus in fertilizers, Method 960.03, is an Official Method for extraction of both P2O5 and K2O. Because K2O is much more soluble and easier to extract than P2O5, the conditions of the extraction procedure are set for efficient extraction of P2O5, and the extraction of K2O is, in effect, a bonus. In 1993, a modified extraction procedure, using an extractant o...

The experiment was conducted at lowland series of wet lands, International Rice Research Institute (IRRI) Farm, Los Banos, Laguna, Philippines. The rice variety PSBRc 82 was raised during wet season (June – October), and the experiment was laid out in randomized block design with four replications. There were eleven treatments viz., control, recommended NPK fertilizer, -N, -P, -K, LCC 3, LCC 4,...
