Testing and evaluation of planting methods on wheat grain yield and yield contributing parameters in irrigated agro-ecosystem of western Uttar Pradesh, India

Abstract

A field experiment was carried out during three consecutive years 2008 to 2009 and 2010 to 2011 at two locations; one at University research centre and another at farmers' fields in Meerut and Muzaffarnagar district of western Uttar Pradesh, India. The objective of the study was to compare the conventional planting methods (22.5 cm) and broadcasting method of wheat sowing with drill planting method [15.0, 17.5, 20.0 cm and paired row (15:25 cm)] for grain yield and its parameters. The experiment comprised of six (15, 17.5, 20, 22.5 and 15:25 cm paired spaced rows and broad casting) treatments arranged in randomized complete block design with three replications in a net plot size of 13 × 8 m. The results over the years of the study revealed that, the germination were statistically at par in drill sowing at 17.5 cm apart rows and broadcasting. Better plant height was noted in drill planting with 17.5, 20 cm rows and 15:25 cm paired rows. However, number of spikelets spike -1 and number of grains spike -1 were statistically similar in drilling at 17.5, 20, and 15:25 cm paired apart rows. Similarly, 1000 grain weight was recorded in drill sowing at 20 cm and 15:25 cm paired rows. The maximum grain yield was obtained through 15:25 cm paired rows drill planting method and it was statistically at par with drill planting method where row spacing was 20 cm. Whereas, drill-planting techniques with row spacing 15 cm was inferior to broadcast method. It may be concluded that, 15:25 cm paired rows and 20 cm drill planting method is suitable for wheat sowing in sandy loam soils of irrigated areas of western Uttar Pradesh.

Effect of sowing techniques on the agroecological parameters of cereal crops

“…В исследованиях применялись полевой, вегетационный и лабораторный методы (Foulkes et al, 2011;Hochman et al, 2009;Naresh et al, 2012;Oyewole, Attah, 2007); свойства почв определялись по общепринятым методикам (Eberbach, Pala, 2005;Foulkes et al, 2011;Malik et al, 2009). Оценка качества посева проводилась в полупроизводственных опытах по основным предшественникам яровой пшеницы (пар, горох, пшеница) в трехкратной повторности по схеме, представленной в табл.…”

“…Среди агротехнических приемов (предшественник, обработка почвы и др.) в получении полноценных всходов зерновых немаловажное значение имеет посев (Chen et al, 2010;Eberbach, Pala, 2005;Foulkes et al, 2011;Naresh et al, 2012). Задача посева состоит в получении дружных всходов посредством оптимального использования способа, срока посева, нормы высева, глубины заделки и распределении семян, ширины междурядий (Chen et al, 2010;Liang et al, 2011;Pandey et al, 2013;Shah et al, 2006).…”
