“…From these results, it may be concluded that wider spacing (25 cm × 20 cm) performed better results on rice. The result is consistent with the findings of Moro et al (2016). Correlation co-efficient and regression of yield attributes were worked out ( Table 2) in order to evaluate their influence on rice yield.…”

Binadhan-19Row spacing Plant densityYield attributes Yield An experiment was conducted at the experimental farm of BINA Sub-station, Gopalganj to determine the effect of spacing on the yield and yield attributing parameters of rice. Four spacings viz. 15 cm × 15 cm, 20 cm × 15 cm, 20 cm × 20 cm and 25 cm × 20 cm were included in the study. The experimental design was a randomized completely block with three replications. Spacing's 15 cm × 15 cm, 20 cm × 15 cm, 20 cm × 20 cm and 25 cm × 20 cm were adopted 49, 42, 36 and 30 hills per square meter, respectively. Results revealed that different spacing performed significantly differed yield contributing characters (plant height, panicle length, number of effective and non-effective tillers, number of filled and unfilled grain, grain and straw yield of rice. Results indicated that the highest plant height (83.40 cm), panicle length (19.73), number of effective tillers per hill (11.00), number of total grains per panicle (87.73), number of filled grains per panicle (70.53), root length (16.07 cm), root weight (38.00 g per five plants), harvest index (38%), grain yield (4.19 t ha -1 ) and straw yield (4.50 t ha -1 ) were found with 25 cm × 20 cm spacing. On the other hand, maximum number of non-effective tillers per hill (1.60) was found in 15 cm × 15 cm spacing. Results of the present study revealed that 25 cm × 20 cm spacing was found to be the best for obtaining maximum grain yield of aus var. Binadhan-19.

“…The lowest number of non-effective tillers (0.80) per stand was recorded under 20 cm × 15 cm spacing. Moro et al (2016) reported that growth attributes were significantly affected by spacing. Wider spacing resulted in the production of more tillers per stand than closer spacing.…”

“…According to Rajput et al (2016) number of tillers/m 2 was significantly higher in wider spacing with 20 cm × 20 cm as compared to other planting geometry. Wider spacing resulted in the production of more tillers per stand than closer spacing (Moro et al, 2016). Highest CGR was observed at spacing 20 cm x 15 cm + inorganic fertilizers, conventional practice (7.88 g/m 2 /day), and RGR at spacing 20 cm × 20 cm + neem and tobacco extract (Table 1).…”

“…Treatment with 20 cm x 20 cm spacing + neem and tobacco extract (7.78 t/ha) recorded significantly higher grain yield over treatment at spacing 20 cm x 20 cm + Matka khad (6.93 t/ha) and 20 cm x 15 cm + inorganic fertilizers, conventional practice (6.69 t/ha) and 20 cm x 20 cm + (Bezbaruha et al, 2011) and more area of land around them to draw the nutrition and more solar radiation to absorb for better photosynthetic process and hence performed better as individual plant (Mohaddesi et al, 2011) and leading to more dry matter production ultimately resulting in yield enhancement. Moro et al (2016) reported that wider spacing of 25 cm x 20 cm and 20 cm x 20 cm, produced 8.06 and 7.56 t ha -1 more grain over the closer spacing of 30 cm x 10 cm and 15 cm x 15 cm. Straw yield of treatment with spacing 20 cm x 20 cm + neem and tobacco extract (17.06 t/ha) was significantly higher over treatment at spacing 20 cm x 20 cm + Matka khad (15.11 t/ha) and 20 cm x 15 cm + inorganic fertilizers, conventional practice (86 t/ha).…”

On Farm Adaptive Research experiment was conducted during the Kharif season 2013 to assess the effect of crop geomerty in the context of climate change on productivity of rainfed rice (Oryza sativa L). Experiment was laid out in Randomized Block Design (RBD) with 3 treatments viz., 20 cm x 20 cm + Matka khad; 20 cm x 20 cm + neem and tobacco extract and 20 cm x 15 cm + inorganic fertilizers, conventional practice, each treatment replicated 9 times. Results of study revealed that significantly higher grain yield (7.78 t/ha), straw yield (17.06 t/ha), test weight (24.99 g) panicle length of (21.12 cm) were recorded in the treatment with 20 cm x 20 cm spacing + neem and tobacco extract. Further, this treatment has higher grain yield (15.17%), test weight (2.96%) and panicle length (17.66%) over the 20 cm x 15 cm spacing + inorganic fertilizers. Also this treatment has 12 and 32.65 % higher straw yield as compared to 20 cm x 20 cm spacing + Matka khad and 20 cm x 15 cm spacing + inorganic fertilizers respectively. Number of tillers/panicle in treatment containing 20 cm x 20 cm spacing + neem and tobacco extract (17.06) was statistically not different than the 20 cm x 20 cm spacing + Matka khad (17.89). The panicle length (20.54 cm) and test weight (24.83 g) at spacing 20 cm x 15 cm + inorganic fertilizers was found to be statistically at par with 20 cm x 20 cm spacing + neem and tobacco extract (24.99 g). Further, highest CGR (7.88 g/m 2 /day) and RGR (0.041 g/g/day) were recorded in treatment with 20 cm x 15 cm spacing + inorganic and 20 cm x 20 cm + Matka khad.. While maximum number of grains/panicle (136.67) was recorded in the treatment having 20 cm x 20 cm spacing + neem and tobacco extract.

“…The space between planting seeds is recommended at 0.25 m. This transplanting spacing has been reported to result in the best rice performance [20][21][22] . The effects of hill and plant spacing on yield and quality of rice have been discussed in numerous published works [9,[23][24][25][26][27][28][29][30][31][32][33][34][35] . In general, rice yield can be significantly boosted with modern cultural practices such as control of inputs (i.e., fertilizer, nutrient, water, and spaying, and chemicals), ideal environmental parameters (air and soil temperature, humidity, solar radiation, soil moisture content and fertility), sensible planting and nursery, and optimum transplanting adjustments for best tillering [21,29,36] .…”

This paper presents the study reports on evaluating a new transplanting operation by taking into accounts the interactions between soil, plant, and machine in line with the System of Rice Intensification (SRI) practices. The objective was to modify planting claw (kuku-kambing) of a paddy transplanter in compliance with SRI guidelines to determine the best planting spacing (S), seed rate (G) and planting pattern that results in a maximum number of seedling, tillers per hill, and yield. Two separate experiments were carried out in two different paddy fields, one to determine the best planting spacing (S=4 levels: s 1 =0.16 m×0.3 m, s 2 = 0.18 m×0.3 m, s 3 =0.21 m×0.3 m, and s 4 =0.24 m×0.3 m) for a specific planting pattern (row mat or scattered planting pattern), and the other to determine the best combination of spacing with seed rate treatments (G=2 levels: g 1 =75 g/tray, and g 2 = 240 g/tray). Main SRI management practices such as soil characteristics of the sites, planting depth, missing hill, hill population, the number of seedling per hill, and yield components were evaluated. Results of two-way analysis of variance with three replications showed that spacing, planting pattern and seed rate affected the number of one-seedling in all experiment. It was also observed that the increase in spacing resulted in more tillers and more panicle per plant, however hill population and sterility ratio increased with the decrease in spacing. While the maximum number of panicles were resulted from scattered planting at s 4 =0.24 m×0.3 m spacing with the seed rate of g 1 =75 g/tray, the maximum number of one seedling were observed at s 4 =0.16 m×0.3 m. The highest and lowest yields were obtained from 75 g seeds per tray scattered and 70 g seeds per tray scattered treatment respectively. For all treatments, the result clearly indicates an increase in yield with an increase in spacing.
