Author(s): T. SHAH AND MD. NAUMAN
Abstract: A two years field study regarding to quantitative and qualitative analysis of effect of maple tree shade in wheat was conducted on sandy clay loam soil. The shade treatments comprised no shade, two, three, four, five, six, seven and eight hours daily shade. Shading had adverse effect on all the parameters under study. There was a progressive decrease in plant height, number of spike bearing tillers/unit area, number of grains/spike, 1000-grain weight and seed yield/hectare with each successive increase in shade hour. The seed yield decreased by 0.97 per cent - 9.43 per cent and 13.91-19.83 per cent as a result of daily shade of 2-3and 4-5 hours, respectively. The decline in yield was further intensified when the shade hours were upsurge to 6-7 which was 29.23-45.25 per cent and reached the maximum of 55.71 per cent with 8h shade. The harvest index, dry matter percentage and grain protein contents of shaded plants decreased to a substantial extent as compared to un-shaded plants.
