“…Lower paddy yield in TR methods might be affected by subsurface hard pan hindering and impeding root growth and development, and ultimately affect the crop growth and grain yield. Yuan-zhi (2015) and Iqbal et al (2019) also concluded higher paddy yield in ridge sowing over transplanted rice, drill and broadcast sowing techniques. All types of DSR methods were more profitable, due to low input cost and higher yield, as compared to puddled TR-planting methods.…”

R ice (Oryza sativa L.) is a staple food crop of more than half of the inhabitants across the globe (Khush, 2004). In Pakistan, after wheat, it occupies 2 nd position. Its cropped area was 3034 M ha and production was 7.410 M tons (Economic Survey of Pakistan, 2019). Among the cereal crops, rice is an important export commodity (Economic Survey of Pakistan, 2019). It contributes 3.1% in value addition to agriculture and 0.6% in the GDP (Economic Survey of Pakistan, 2019). The average yield of rice in Pakistan is about 2.44 t ha -1 (Economic Survey of Pakistan, 2019) which is low as compared to other rice producing countries due to many constraints including proper crop establishing techniques (Aslam, 2016).In Asia rice is growing by transplanting, rice seedlings manually in puddled soil which is a widely adopted method. It consumes abundant water (Bouman and Tuong, 2001). Whereas, water resources are declining day by day. Its judicious use is gaining a pivotal importance to fulfil future water and food demand for the growing population (Mahajan et al., 2012). Shrinking water resources availability is a threat for the future rice production in Asia (Mahajan et al., 2012) and will adversely affect the sustainability of Abstract | Planting method is an important aspect of production technology for the maximum resource utilization by crops per unit area. Dry-seeded rice (DSR) is a contemporary resource saving crop establishing technique, which enables farmers to harvest economical rice production. Field study was conducted at Rice Research Institute, Kala Shah Kaku, Pakistan in 2014 and in 2015 to evaluate the different planting methods. Three dry-seeded rice (DSR) planting methods viz. (i) DSR-broadcast, (ii) DSR-drill, (iii) DSR-ridges were compared with the conventional transplanting (TR) method in lines having row to row and plant to plant distance of 22.5cm distance, and farmer transplanting method. Experimental design was randomized complete block, replicated 3 times. Data were recorded on height (cm), tillers m -2 , filled and unfilled grains panicle -1 , thousand grain weight (g), grain and biomass yield (t ha -1 ). Grain sterility (%) and harvest index (%) were also calculated. Highest grain yield (5.00 to 5.11 t ha -1 ) with harvest index (30.00 to 31.50%) and relatively low grain sterility (12.00 to 12.01%) were observed in DSR-ridge and DSR-drill sowing method. Moreover, DSR (i.e. DSR-ridge and -drill) resulted in 104 and 76 % more profit over TR-farmer practice. The study concluded that DSR-ridge and DSR-drill proved to be the best to obtain the maximum paddy yield and net profit. Farmers can adopt these methods to harvest maximum benefit.

“…Majeed et al (2015) compared ridge tillage system and flat tillage system and found that the former system improves nitrogen use efficiency and yield production than the latter system as a result of reduction in leaching. In a study by Yuan-zhi (2015) on rice (Oryza Sativa L.), ridge tillage system increased root number, root absorption, stomatal conductance, photosynthesis rate, and water use efficiency, gas exchange, antioxidant enzyme activity, panicle number and yield by between 22.12 and 15.18%. Therefore, the objective of this study was to determine the effect of ridge and flat tillage system on soil physical properties, root growth and production of Kingbird and Kwale spring wheat.…”

Tillage system is one of the main factors influencing growth and physiology of wheat (Triticum aestivum L.), that eventually translates to high yield and good kernel quality. The objectives of this study were to determine the effects of the ridge (RT) and flat tillage (FT) systems on (i) growth and production of spring wheat, (ii) root growth and physiology and (iii) soil physical properties. Trials were conducted at Kenya Agricultural and Livestock Research Organization, Njoro and Egerton University. A randomized complete block design (RCBD) in a split plot arrangement with tillage system as the main plot and cultivar as sub-plot was used in the study. Data analysis was done using PROC GLM procedure from SAS software version 9.4. The study showed that root length, surface area and volume were 34.66, 42.17 and 47.56% higher in RT than FT, respectively. The RT had 8, 7.66, 39.19 and 20% higher NDVI, TKW, yield and HI, than FT. Soil moisture and electrical conductivity were 38.43 and 9.02% higher in the RT than FT. Soil temperature and BD were 1.05 and 38.94% higher in FT than RT. The RT provided a conducive environment for wheat growth and physiology, resulting in high yield and kernel quality.

“…Several studies have demonstrated the potentials of ridge tillage in providing favorable physical conditions in soil, leading to improved growth and yield of plants grown under harsh dry environments (Gürsoya et al, 2011). Previous researches have shown that crop yields were often higher under ridge tillage than conventional tillage systems (Mert et al, 2006;Yuan-zhi, 2015). The spectacular growth and yield performance associated with ridge tillage has almost always been attributed to better soil conditions as reflected by reduced soil bulk density and penetration resistance, increased soil permeability (Gürsoy et al, 2011), enhanced root growth and gas exchange (Yuan-zhi, 2015), and adequate supply of moisture, leading to greater nutrient uptake by plants (Lal, 1990;Hatfield et al, 1998).…”

Ridge tillage (RT) and organic manure management are among promising agronomic practices for conserving soil moisture and improving soil physical environment in arid and semiarid rain-fed areas. The studies were conducted during the year 2020 farming season with two soil types from northeastern part of Nigeria to compare the relative efficacy of RT with and without organic manure in improving soil physical properties and root growth of millet under rain-fed semi-arid condition. The effects of the RT treatments in combination with organic manure were compared to the conventional flat-bed treatment (control, FB). The soil types chosen for the study were sandy loam soil located at the University of Maiduguri (Unimaid) and sandy clay loam located at Alakaramti village, respectively. The other land configuration and manure treatments compared were: open-ridge (OR), tied-ridge (TR), flat bed + manure (FBM), open-ridge + manure (ORM), and tied-ridge + manure (TRM) each laid out in randomized complete block design with four replicates. The combination of RT (open or tied) plus organic manure (ORM & TRM) performed better in terms of all measured parameters: bulk density (Bd), porosity (Tp), mean weight diameter (MWD), soil water content (SWC) and root growth as measured with root mass density (RMD) than the bare ridge-tilled (OR & TR) or flat bed with manure (FBM) and without manure (FB) treatments, irrespective of differences in soil type. The improvement in soil condition resulting from combining the practices of RT with organic manure application as reflected by reduced Bd, increased Tp, and higher profile SWC has enhanced millet root growth under the water limited rain-fed farming system of the study area. In regions like northeast Nigeria where low and variable rainfall often limits crop production, the practice of combining RT(open or tied) with organic matter input could be recommended as an optimal agronomic practice for improving drought resilience of crops like millet.
