“…A recently developed technique for double harvesting (ratooning) of forage rice can give very high yields of DM (Nakano and Morita, 2007, 2008; Nakano et al, 2009b) and total digestible nutrient (Nakano et al, 2009a, 2010, 2011), but this requires a long growth duration. It is best suited to the southern part of southwestern Japan, where the climate is warmer than in the northern part.…”

Forage rice (Oryza sativa L.) has attracted attention as a potential crop in Japan, but no optimal agricultural product system has been extensively established. The objective of this study was to determine the effects of cultivar (high‐yielding indica cultivar Hokuriku 193, high‐yielding indica‐japonica hybrid cultivar Mizuhochikara, or standard japonica cultivar Akisayaka) and sowing pattern (broadcast or drilling) on grain yield using a new sowing machine for a well‐drained paddy field. Hokuriku 193 had the highest grain yields. Hokuriku 193 and Mizuhochikara had much more spikelets than Akisayaka. Hokuriku 193 and Akisayaka had a higher percentage of filled spikelets than Mizuhochikara. At full heading, Hokuriku 193 had the highest nonstructural carbohydrate (NSC) amount. Thus, the high NSC amount of Hokuriku 193 supported a high grain yield and high percentage of filled spikelets in spite of its very many spikelets. Broadcast gave a higher rough grain yield, grain yield, and number of panicles than that of drilling, but it had no effect on the percentage of filled spikelets or the 1000‐grain weight. At full heading, broadcast gave a higher NSC amount than drilling. Therefore, broadcast of high‐yielding indica or indica‐japonica hybrid cultivars might increase grain yield, in spite of its very high panicle number, without decreasing the percentage of filled spikelets or the 1000‐grain weight by increasing the NSC amount at full heading.

“…Previous studies indicate that the main crops cutting height that effectively increase the yield of rice ratoon were strongly influenced by location, season, varieties and cultivation of rice. The application of cutting height of 0-15 cm above the soil surface gave higher ratoon yield and harvest index on rice ratoon (Nakano et al, 2009;Petroudi et al, 2011;Setiawan et al, 2014). Medium cutting height of 20-30 cm above the soil surface can optimize ratoon yield per panicle (Harrel et al, 2009;Huossainzade et al, 2011;Susilawati et al, 2011;Beuzelin et al, 2012).…”

Rice Ratoon Yield Response to Main Crops Cutting Height in Tidal Swamp Using Direct Seeding System

et al. 2016

This study was aimed to evaluate the effect of main crops harvest cutting height on the yield of rice ratoon in the tidal swamp by using direct seeding system. The experiment was conducted in Telang Sari village, District of Tanjung Lago, Banyuasin, South Sumatra Province from November 2013 to April 2014. It measured plots 4 x 5 m through a randomized block design with 5 replications. The treatment was main crops harvest cutting height of 10, 20, 30, 40 and 50 cm above the soil surface. The results showed that the effect of cutting height on rice ratoon yield depends on the condition of photosynthetic and the amount of remaining nodes on the main crops stubble as an emergence ratoon shoots. The main crops cutting height of 20-40 cm above the soil surface increased the number of productive tillers, grain weight per hill, yield per plot, ratoon ability to grow per plot, and the rice ratoon/main crops yield ratio in tidal land by using direct seeding system.

“…In forage rice production, it is important to maximize the nutrition in leaf and stem, especially stem due to the high ratio to the whole plant weight, rather than in panicle, to minimize the overall loss of nutrition from the crop because the hull restricts cattle's ability to digest rice grain (Hara et al, 1986; Nakui et al, 1988; Hosoda et al, 2005) and combine harvesters drop large amounts of grain (Nakano et al, unpublished data). Recently, we found that double harvesting is an effective way of reducing the overall loss of nutrition from crop (Nakano et al, 2009a). In the double‐harvesting system, the first crop is harvested by a forage harvester, and growers are concerned about the potential effects of cutting height and equipment traffic of the first crop on TDN concentration and yield in the first and second crops.…”

We examined the effects of cutting height (15, 5, or 0 cm) and equipment traffic treatment (treatment or no treatment) of the first crop on estimated total digestible nutrient (TDN) concentration and yield in double‐harvested forage rice (Oryza sativa L.) in southwestern Japan. In forage rice production, it is important to maximize the nutrition in leaf and stem, especially leaf sheath plus stem (stem) due to the high ratio to the whole plant weight, rather than in panicle, to minimize the overall loss of nutrition from the crop. In the total of the first and second crops, stem estimated TDN yield was lower when the first crop had been cut at a height of 15 cm (517 g m−2) than 5 and 0 cm (576 and 598 g m−2, respectively). In the second crop in 2006, stem estimated TDN concentration decreased from 541 to 478 g kg−1 with increasing cutting height from 0 to 15 cm, because the organic cellular contents (OCC), which include starch and sugar, concentration decreased. The second crop headed earlier with increasing cutting height. Thus, although starch was translocated from the stem to the panicle in the second crop when the first crop was cut at a height of 15 cm, insufficient starch was translocated to the panicle when the first crop was cut at 5 and 0 cm because of the low temperatures after heading. To reduce the overall loss of nutrition from a crop, it is effective to cut stubble lower. In the second crop, whole plant estimated TDN concentration and yield was not greatly influenced by equipment traffic treatment.
