“…In present study increase in grain yield by increasing the puddled soil settling period along with 25 days old nursery seedlings caused an increase in the gross income and net returns which ensued in higher BCR (Table 7). Previous studies have reported that better management of MTR causes an increase in yield and reduces the yield losses which consequence in better net returns and BCR (Dongarwar et al, 2018;Zohaib et al, 2022).…”

R ice (Oryza sativa L.) is cultivated and utilized as staple food in a large number of countries over the world. Traditionally, rice is planted by transplanting nursery manually in the puddled soil that is quite strenuous and time consuming (Thomas, 2002;Farooq et al., 2007). In recent years, a marked increase in labor Abstract | Seedling age and soil condition after puddling affects stand establishment, growth and productivity of mechanically transplanted rice (MTR). Study was performed to evaluate different puddled soil settling periods (24, 48 and 72 hours) and seedling age (20, 25 and 30 days) for decreasing the missing hills while improving plant and root growth, and consequently grain yield of MTR. Experiment was conducted using randomized complete block design (RCBD) with split-plot arrangement and three replications during 2020 and 2021. Shoot and root length as well as dry mass of rice seedlings sown in trays were significantly increased with increase in seedling age. Increase in puddled soil settling period and seedling age significantly interacted in increasing filled hills and decreasing missing hills after transplanting the nursery. Root length, plant height and root/shoot ratio was significantly higher at 72 hours puddled soil setting period; however, seedling age didn't affect plant growth. The productive tillers, total dry matter (TDM) and grain yield of MTR was improved interactively by 72 hours puddled soil settling period and 25 days old nursery. The 1000-grain weight was increased by increase in puddled soil setting period while didn't affect significantly by seedling age. Benefit cost ratio (BCR) and net returns were substantially improved by 72 hours puddled soil settling period and 25 days seedling age. In conclusion, 72 hours puddled soil settling period and 25 days seedling age improved the yield and economic returns by decreasing missing hills; hence could be employed to enhance yield and economic benefits of MTR.

“…However, highest net returns and BCR was recorded by using 90 g seed per tray which was associated with better grain yield (Figure 2 a,b) and hence gross income (Table 5). Previous studies have reported that aside from sowing method of rice the optimum seeding rate enhances the grain yield which ensues in higher economic returns and BCR, minimize economic losses and hence must be adopted to enhance crop productivity and economic benefits (Corbin et al, 2016;Dongarwar et al, 2018;Li et al, 2020).…”

“…Conversely, high seeding rate increases the plant population and plants per hill but produces poor quality seedlings (Yu et al, 2006;Hossen et al, 2018). Nonetheless, the seeding rate per unit area varies for coarse and fine types of rice (Dongarwar et al, 2018). Similarly, seeding rate in MTR also varies for short, medium and long rice types (Hossen et al, 2018).…”

Mechanical transplanting with mat type nursery is quite a new planting technique for rice. However, optimization of seeding rate for producing mat type nursery is crucial to acquire suitable seedlings and planting density for better yield of mechanically transplanted rice (MTR). Current 2-years field study was conducted to determine effect of seeding rate (80, 90, 100 and 110 g per tray) for preparing nursery mats of fine basmati rice on plant growth, grain yield and economic benefits. Seeding rate significantly affected the growth, yield and related traits of fine basmati rice. Increase in seeding rate from 80 to 110 g per tray successively increased number of plants per tray and per hill after transplanting while decreased the root length and root/ shoot ratio of rice. Plant height was not affected significantly by seeding rate. Highest increase in number of productive tillers (8%), 1000-grain weight (8%), total dry biomass (14-17%) and grain yield (10-16%) was caused by 90 g seed per tray, as compared to 110 g seed per tray. Order of grain yield produced by different seeding rates was 90 > 80 > 100 > 110 g per tray. Economic analysis exhibited that maximum net returns and benefit cost ratio (BCR) was achieved by using 90 g seed per tray. In conclusion, 90 g seed per tray improved the grain yield by enhancing number of productive tillers and grain weight of fine basmati rice; hence, could be adopted for better productivity and economic benefits of mechanically transplanted fine basmati rice.

“…Irrigation is provided on continuous basis to keep standing water in the field which also causes water loss because of evaporation, puddling process and percolation (Mann et al, 2007). Rice crop production is laborious and time-consuming as its field management requires larger number of manpower and availability of irrigation water, which also makes it very expensive (Singh, 2013;Dongarwar et al, 2018;).…”

“…Plant population is determined by the seed rate which also have influence over the crop growth, its competitiveness and ultimately the yield. Poor sowing method leading to low plant density are the main constraints posing a threat to crop growth and have a negative influence on the yield of rice (Sivaesarajah et al, 1995;Dongarwar et al, 2018). This study was planned to find out the suitable seed rate and their effect on yield and yield related attributes by drill sowing of coarse and fine rice varieties.…”

Rice is the most important cereal crop that plays a multifarious role in the agricultural economy of Pakistan along with its utilization as second staple crop after wheat. The production capacity of varieties in all crops mainly depend on optimized seed rate. We carried out this study at Rice Program NARC during the kharif 2021 to find out the optimal seed rate of most cultivated varieties of fine (Super Basmati) and coarse rice (IR-6) in Pakistan by using direct seeded rice (DSR) drill sowing method with four varied seed rates i.e 11kg, 9kg, 7kg and 5kg/acre. Paddy yield depended on different yield related attributes i.e plant height, total number of plants/m2, total tillers/m2, number of productive tillers/m2, panicle length, number of grains/m2 and yield. Our results indicated that maximum grain yield was obtained at seed rate 11kg (3149.915 kg/acre and 1598.565kg/acre) in IR-6 and Super basmati respectively. Lowest yield was observed at 5kg seed rate (2239.34kg/acre and 836.38kg/acre) in IR-6 and Super Basmati. Based on these findings, it is concluded that using optimal seeding rate of 11kg/acre for direct seeded fine and coarse rice cultivars is beneficial in terms of productive tillers and higher yield.
