Effect of bed planting and zero tillage on productivity and water use of Irrigated maize - wheat cropping system in Khyber Pakhtunkhwa province of Pakistan

Imtiaz Hussain Muhammad Imtiaz (2018)

Crop establishment methods like broadcasting of wheat and manual planting of maize on flat surface coupled with flood irrigation are used in irrigated maize–wheat system of Khyber Pakhtunkhwa (KP) province that requires skilled labor, intensive tillage and more water for irrigation. In this study, zero tillage and bed planting effect in comparison with farmer practice on maize-wheat system productivity was evaluated at five sites in district of Nowshera, KP province during 2014-2016. Maize grain yield with bed planting and manual planting on flat surface were non-significantly different. Because of weed infestation, there was 30 percent lower maize grain yield with zero till planted maize in comparison with bed planting and farmer practice. Zero till drill planted wheat after maize crop had higher grain yield in comparison with mechanized bed planting and farmer practice of broadcasting in 2014-15 and 2015-16 wheat season. Because of higher maize grain yield, maize–wheat system productivity was significantly higher with bed planting and farmer practice in comparison with Zero tillage. Bed planting of maize had 20 – 30 percent higher water use efficiency (WUE) in comparison with flat planting of farmer practice in both the years. Overall comparison of maize – wheat cropping system showed that there were 16 and 22 percent water saving with bed planting in comparison with other practice in 2014-15 and 2015-16 cropping cycle, respectively. The study showed that farmer practice of manual planting of maize and broadcasting of wheat can be replaced with bed planting of maize and zero till drill planting of wheat, respectively to save water, labor and improve maize-wheat system productivity and water use efficiency.

Nutritive appraisal of various wheat varieties/lines for developing biofortified wheat (Triticum Aestivum L.)

Abdullah Mamun Muhammad Imtiaz (2018)

Essential micronutrients such as iron and zinc deficiencies affect more than two billion people globally especially the pregnant women and children below the age of five. Wheat, like many other staple cereals, contains low levels of the essential micronutrients iron and zinc. It contributes 13.1 percent to the value added in agriculture and 2.8 percent to GDP of Pakistan. National Wheat Breeding program at Faisalabad, Pakistan analyzed 240 samples of wheat varieties/lines both from irrigated and rainfed conditions. The analysis revealed that 1000 grain weight ranged from 23.9-50.2 in irrigated and 31-42.0 g in rain-fed conditions while test weight range was found to be 59.9-75.8 (irrigated) and 64.5-79.9 Kg hl-1(rain-fed). Protein and gluten content ranged between 12.0-16.1 & 13-16.2 and 21-34 & 21-38% in irrigated and rainfed trial, respectively. Starch content was found to be 51.8-57.1 and 51.9-56.1% in irrigated and rain-fed set, respectively. Falling No. (FN) values were recorded in the range of 352-814 in irrigated and 352-814 sec in the rain-fed set. Most of the varieties/lines had narrow range of Zn (31-32.6 & 31.2-33.9) and Fe (35-40 & 35-43 ppm) in irrigated and rainfed trial, respectively. In irrigated, conditions, cluster 3(5 genotypes) represented relatively high value of Fe and Zn contents while in rainfed condition, cluster 2 (31 genotypes) and cluster 3(15 genotypes) represented relatively high value Zn. Statistical analysis of both sets showed gluten & protein being directly correlated to each other, showing a positive correlation with Fe & Zn but a negative one with starch. In both sets, a direct correlation of FN with starch was observed only in rainfed set It is believed that mobile-phone enabled agro-advisory services have the potential to reduce information gaps and generate awareness about improved technologies which leads to improved adoption of technology. Through the pilot study, we show how climate services helped in enhancing farmers’ awareness about the CSAPs.
