“…Seedling was raised at the FPMD workshop with hybrid rice seed, Moyna (HTM303) of Laal Teer Seed Company Ltd. Seed rate was maintained 120 gm per tray for hybrid rice (Sarkar et al, 2019). Seedling was grown on plastic tray and was covered with polythene due to cold weather.…”

Unpuddled transplanting of rice as a part of conservation agricultural practice has become significant due to its protective behavior for soil properties and economic profitability. Mechanical transplanting in unpuddled soil using hybrid rice variety leads to a high yield with minimum transplanting time and cost, securing soil nutrients. A study was conducted in Bangladesh Agricultural University to evaluate the efficacy of mechanical transplanting of hybrid rice in unpuddled soil considering field and financial performances of rice transplanter. The experiment was conducted during Boro-2018 season with a Daedong DP-480 rice transplanter. Hybrid rice seed Moyna (HTM303) of Laal Teer seed company Ltd. was used for transplanting at a seed rate of 120g per tray and seedling per hill was adjusted to 2-3 nos. In unpuddled soil, transplanter possessed an effective field capacity, fuel consumption and efficiency of 0.16 ha/h, 4.8 l/ha and 67.48%, respectively. Transplanting time included an idle time of 11% due to clogging with mud. Missing hill percentage was found as 6.1% with a floating hill of 7.36%. Plant heights were 15.72 cm and 86.19 cm at the day of transplanting and at the day of harvesting, with tiller per hill of 18 nos. The average panicle length of plants was found as 23.6 cm where traditionally transplanted rice has panicles of 21.2 cm average. The yields of mechanically transplanted rice in unpuddled soil condition was 5.21 ton/ha and the yield of mechanical transplanted rice in unpuddled soil was found to be 27.07% higher than traditionally transplanted rice. The BCR and IRR of mechanical transplanting in unpuddled soil was found 1.57 and 55% considering 10% discount factor. The payback period, after which the transplanter will overcome its costs, was found 1.68 years. Financial analysis reveals that mechanical transplanting with this field capacity will be beneficial if the transplanter is used to transplant 19.77 ha annually.

“…Effect of ideal seeding rate for cultivars of rice on weight of 1000 grains (gm). The results showed in table(6) a significant different between rice cultivars, where cultivar D was significantly superior on Unfertility compared to cultivar B and Y for seasons 2019 and 2021, who gave the highest value with decrease ratio 46.11, 28.70% respectively. The results of the table indicated there were a significant affected between the experimental treatments when added seeding rate where 80 and 60 Kg ha -1 was significantly superior on Unfertility compared to 140 and 120 Kg ha -1 for both seasons, respectively who gave the highest value with decrease ratio 18.30, 28.09%.…”

“…Agricultural mechanization using small-scale machines for agricultural production has been one of the outstanding developments in developed countries [5]. The seed rate is very important as the growth of seedling and also the agronomic parameters of transplanting depend on it [6]. If the seed rate is higher than the optimum, the growth of the seedling is obstructed by nutrient deficiency.…”

This study aimed to determine the optimum seeding rate of rice (Oryza Sativa L.) cultivars in iraq. The experiment was conducted at Al Diwaniyah Research Station, Agricultural Research Office/Ministry of Agriculture for two seasons 2019 and 2021. A Factorial Experiment Design was used According to RCBD design in an order of split plot with three replicates, The main plots occupied the cultivars factor which was: - Yasamine (Y), Forat (F), Dijla (D), Baraka (B), Gadeer (G) and Anbar (A). While the seeding rate factor filled sub plots: - 40, 60, 80, 100, 120, 140 Kg ha-1. The research results for both seasons, indicated that each cultivar had an ideal seeding rate, as the seeding rate for the Y variety is 120 kgha-1, as it gave the best leaf area, the weight of 1000 grain, and the grains panicles-1, which was reflected in the best grain yield at this level. The results also showed that the seeding rate for the F variety was 140 kgha-1, as it gave the best plant height, panicles m-2, weight of 1000 grain, and grains panicles-1, thus giving the best grain yield at this level. The results showed that the seeding rate for variety D was 140 kgha-1, which gave the best plant height, leaf area, panicles m-2, and grains panicles-1, which reflected positively on the best grain yield at this level. The results indicated that the seeding rate for variety B was kgha-1, as it gave the best plant height, panicle m-2, unfertility, and grains panicles-1, which was reflected in the best grain yield at this level. As for the G variety, the best seeding rate was 120 kgha-1, as it excelled in all the studied treatments (plant height, panicle length, leaf area, panicles m-2, weight of 1000 grain, unfertility, and grains panicles-1), which was significantly reflected on the grain yield at this level. Whereas, cultivar A showed that the best seeding rate was 140 kgha-1 if it gave the best plant height, leaf area and panicles m-2 and thus gave the best grain yield at this level.
