Wheat Crop Growing In Fibres Technique In Saline Water Irrigation Condition Of Semi-Arid Region.

Abstract

A field experiments was conducted during rabi seasons of 2010-2011 to 2012-2013 at the AICRP-Management of Salt Affected Soils and Use of Saline Water in Agriculture, Farm, Raja Balwant Singh College, Bichpuri, Agra (U.P.). Treatments consisted of combination of irrigation with waters of three varying salinities viz. Best available water (BAW) , ECiw 8 and 12 dS/m , three IW/CPE ratio ( 0.3, 0.6 and 0.9) and two method of sowing flat ( conventional method of sowing) and bed method of sowing. The findings of present investigation indicated that the grain and straw yields as well as most of the growth and yield attributes of wheat were significantly influence due to different irrigation schedule, salinity levels and methods of sowing. The results further revealed that growth attributes such as plant height (cm), dry matter (gm), effective tillers plant m-1, ear spike length (cm), grain weight spike-1 (gm), grain yield plant-1 (gm) and test weight (gm) were significantly higher in bed method of sowing salinity levels and IW/CPE ratio. The highest grain yield recorded in BAW treatment. The highest grain yield of 43.9 q ha-1 in 2010-11 , 41.2 in 2011-12 and 35.9 in 2012-13 recorded in BAW treatment with bed sowing method in IW/CPE ratio 0.9. The same trend was observed in straw yield in both all the years in wheat crop. The highest WUE 36.7, 37.7 and 35.9 kg ha-1 mm) was recorded in flat method of sowing in 2010-11, 2011-12 and 2012-13 in IW/CPE ratio 0.9, respectively.
