...and in combinations with gypsum (1000 kg ha-1) as inorganic soil conditioner were applied a week before sowing of maize. Design used was randomized complete block with split plot arrangement replicated thrice. Experimental site was Agronomy Research Farm, The University of Agriculture Peshawar. Irrigations regimes were subjected to main plots while soil conditioners to subplots. Results of the two years study indicated that most of the yield and soil parameter...

CUMULATIVE EFFECT OF SULFUR AND CALCIUM ON WHEAT GROWTH AND YIELD UNDER SALINE-SODIC SOILS
...effect of three rates of gypsum on growth and ionic concentration of -1 wheat variety (Saher) sown in saline-sodic soil (ECe=5.32 dS m , pH=8.52 and SAR=18.87) at Soil Salinity Research Institute (SSRI) Farm, Pindi Bhattian during rabi 2009-10. Treatments were arranged using randomized complete block design (RCBD) with three replications. The crop was harvested at maturity, data on tillering, plant height, spike -1 length, number of grains spike , 1000-grain w...

COMPARISON OF GYPSUM AND POTASSIUM SILICATE FOR RECLAMATION OF SALINE SODIC SOIL
...p;Relative efficiency of gypsum, potassium silicate and their combinations at different levels for reclamation of saline sodic soil was tested. Treatments were replicated thrice. All pots were arranged according to completely randomized design and treatments were applied to the soil according to treatment plan. Appropriate time was given to achieve the reclamation of saline sodic soil and relative efficiency was assessed through laboratory analysis. After this...

DETERIORATION OF ORDINARY PORTLAND CEMENT AND FLY-ASH BASED GEO-POLYMER CONCRETES DUE TO SULFATE ATTACK UNDER THE ACTION OF SULFURIC ACID AND WASTEWATER
...ly. Reaction products of gypsum remained on the surface of concrete samples absorbed in diluted sulfuric acid, while reaction products of gypsum were not seen on the surfaces of concrete samples absorbed in static as well as dynamic wastewater. Static wastewater also produced corrosion but in a limited fashion, it causes only surface weathering. The obtained results are strongly confirming that geopolymer ...

Effect of Temporal Application of Gypsum on Mineral Uptake and Economically Important Morphometric Traits in Groundnut (Arachis hypogea L) under Rain-fed Conditions
...tudy, various regimes of gypsum application and its effect on groundnut yield, morphometric parameters, and minerals (Ca, K, P) concentration in root and shoot have been examined. A newly released Pothowar groundnut variety (Variety name) was grown in 3 replications with 5 m row length using a randomized complete block design. Five different treatments were applied in two split doses i.e. T1 (0 %:100 %), T2 (25 %:75 %), T3 (50 %:50 %), T4 (75 %:25 %), and T5 (...

Data showed that the highest biomass and paddy/grain yield were produced by canal water (T1) followed by (T3) where three irrigations of tube well water and two of canal water were used in a short cyclic manner. Whereas, growth and yield of rice and wheat crops were significantly reduced by continuous use of brackish water (T2) and maximum pHs, ECe a...

Socioeconomic characteristics of the adopter farmers have also been studied. The study is based on primary data that was collected from 110 sample farmers in the year 2018. It is found that adopters of the gypsum technology are more educated, having large family size, ope...
