The experiment was conducted at the Research Farm of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during 14 August to 7 December, 2008 to study the effects of organic fertilizer on yield performance of five fine rice cultivars viz., Rajshahi Swarna, Silkumul, Kataribhog, Lal Pajam and Sanla. The experiment was laid out in a split plot design with three replications. Effective tillers hill-1, plant height, panicle length, filled grains panicle-1, total grains panicle-1, 1000-seed weight, grain yield, straw yield and harvest index (HI) were significantly influenced by the combined effect of cultural conditions and rice cultivars. Under inorganic and organic culture, the highest grain yield was obtained from Rajshahi Swarna (2.90 and 2.74 t ha-1, respectively) and the lowest were from Sanla (2.20 and 1.74 t ha-1, respectively). All the cultivars showed better performance in respect of grain yield and other parameters under inorganic culture than organic culture.

Variations in the phenology and degree days of five fine rice cultivars viz., Rajshahi swarna, Silkumul, Kataribhog, Lal pajam and Sanla under organic and inorganic cultural conditions were studied following a split plot design. The requirement of days to attain various phenological stages was highest in Rajshahi swarna, medium in Silkumul, Kataribhog and Lal pajam and the lowest in Sanla for both the cultural conditions. The growing degree days (GDD) and heat use efficiency (HUE) were slightly higher under inorganic than organic culture because of higher life span of rice cultivars in inorganic culture. The highest GDD and HUE were found in Rajshahi swarna, whereas the lowest in Sanla. Results also showed that the requirement of days and GDD were initially higher up to maximum tillering stage under organic culture but thereafter these requirements were greater under inorganic culture for all the cultivars. The grain yield was somewhat lower in organic compared to inorganic culture. In Rajshahi highest grain yield of swarna was 2.90 and 2.74 t/ha under inorganic and organic culture, respectively.

Shortage of water in rice cultivation is major problem in India. To safeguard and sustain food security in India, it is quite important to increase the productivity of rice under limited water resources. To investigate the performance of rice cultivars under the best method of irrigation and system of cultivation in new condition an experiment was conducted to study the "productivity and water use efficiency of rice (Oryza sativa L.) cultivars under different irrigation regimes and systems of cultivation" on clay loam soils of Indian Institute of Rice Research (IIRR), Rajendranagar, Hyderabad, Telangana during the kharif seasons of 2017 and 2018. The treatment comprised of two irrigation regimes viz., AWD and saturation as main plot treatments, three establishment methods viz., system of rice intensification, drum seeding and TP as subplot treatments and four cultivars namely DRR Dhan 42, DRR Dhan 43, MTU-1010 and NLR-34449 as sub-sub plot treatments summing up to 24 treatment combinations laid out in split-split plot design with three replications. Among the irrigation regimes, AWD irrigation practice recorded higher grain yield (5755, 5952 and 5854 kg ha-1 in 2017, 2018 and pooled means, respectively) than saturation. Among the different systems of cultivation, the SRI recorded significantly higher grain yield (5953, 6129 and 6041 kg ha-1 during 2017, 2018 and in pooled means, respectively) over the TP method. Among the different rice cultivars, DRR Dhan 43 registered remarkably higher grain yield than other cultivars during 2017 and 2018.

Grain Yield And Quality

High-yielding rice cultivars with good processing quality and rich in nutrition suitable to a changing climate are of particular importance for future rice-based food production. Here, seven Rwandan rice cultivars were grown in a climate chamber of the biotron facility at the Swedish University of Agricultural Sciences, to be evaluated for their grain yield, nutritional composition, and dough mixing properties. Two different levels of inorganic fertilizer were applied weekly from the seedling stage until flowering. Significant differences for grain yield and quality attributes were found between cultivars. Jyambere showed significantly the highest yield while Ingwizabukungu, Nemeyubutaka, and Jyambere were high in mineral elements content. Ndamirabahinzi and Mpembuke had the highest levels of TPC and TAC. Generally, the lower fertilizer dose resulted in a better performance of the cultivars for both yield and quality attributes. Significantly higher content of Fe, Ca, and Ba was found in grains from the moderate fertilizer dose, whereas K, Na, P, S, Zn, Cd, and Pb increased in grains from the higher fertilizer dose. The cultivar Ndamirabahinzi showed less variability of evaluated characters across fertilizer doses. The results from this study may be used for rice breeding of cultivars with high yield and good grain quality.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to November 2016 in order to find out the effect of variety and planting arrangement on weed control and yield performance of transplanted Aman rice. The experiment consisted of four varieties viz., Binadhan-7, Binadhan-12, Binadhan-17 and Binadhan-16 and five planting arrangement viz. 25cm × 20cm, 25cm × 15cm, 20cm × 20cm, 20cm × 15cm and 15cm × 15cm. The experiment was laid out in Split Plot Design with three replications. Results indicated that the highest weed density (90.93 m-2), weed biomass (131.87 gm-2), leaf chlorophyll content (SPAD value) (40.02), sterile spikelets panicle-1 (76.86) ,% sterility panicle-1 (28.66), grain yield (4.51 t ha-1) and straw yield (4.63 t ha-1) were obtained from Binadhan-17. The variety Binadhan-7 showed the best performance in respect of number of total tillers hill-1 (11.06), number of effective tillers hill-1 (10.12) compared to the other varieties used in the study. The highest leaf chlorophyll content (SPAD value) (36.48), plant height (99.72 cm), panicle length (22.03 cm), number of total tillers hill-1 (10.21) and number of effective tillers hill-1 (9.45) were found at 25 cm × 20 cm planting arrangement. The highest grain yield (4.31 t ha-1) was recorded from 20cm × 15cm planting arrangement. The interaction between variety and planting arrangement showed numerically higher grain yield (5.38 t ha-1) from Binadhan-7 at 20cm × 15cm planting arrangement, whereas the lowest grain yield (2.61 t ha-1) was achieved from the variety Binadhan-12 at 15cm × 15cm planting arrangement. It can be concluded that Binadhan-7 at 20cm × 15cm planting arrangement may be used for achieving the best yield with less weed interference in Aman season.

A field experiment was conducted during Summer and Kharif seasons of 2007-08 and 2008-09 at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India to study the effect of hand weeding and Pretilachlor 50 EC @ 500 g a.i. ha-1 as pre-emergence on weed management of different varieties of hybrid and high yielding rice. The experiment was laid out in a split-plot design with three replications for both the years. It has been observed that Pretilachlor 50 EC @ 500 g a.i. ha-1 has a significant effect to control complex weed flora both in hybrid and high yielding varieties of rice but hand weeding twice gave the better result as expected. Among the varieties, the hybrid varieties recorded 36% and 32% more grain yield in Summer and Kharif seasons respectively than high yielding varieties (HYV). The high yielding variety 6444 (V2) showed more grain yield during Summer and Kharif seasons than that of the hybrid 6129 (V1), 97158 (V6), and 96110 (V3), respectively. Regarding weed management, hand weeding twice recorded (13% & 36%) higher grain yield during Summer than that of the chemical treatment and unweeded check, and (20% & 42%) during Kharif seasons respectively. Among the interaction, hand weeding combined with all varieties of hybrid rice recorded higher yield in comparison to other treatment combinations.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2013 in the aman season to investigate the effect of age of seedling and nitrogen rates in the nursery bed on growth, yield and yield components of BRRI dhan52. The experiment comprised of three ages of seedlings viz., 30, 35 and 40 day old and four nitrogen rate N1-N@50 kg ha-1, N2-N@75 kg ha-1, N3-N@100 kg ha-1, N4-N@125 kg ha-1. The experiment was laid out in a split plot design with three replications. Age of seedling showed significant differences for shoot weight, survivor, no. grains panicle-1, panicle length, grain yield and straw yield. The highest root weight (0.072 gm-2), plant height (108 cm), total tillers hill-1 (8.22), effective tillers hill-1 (7.03), non-effective tillers hill-1 (1.19), survivor (95.1%), grains panicle-1 (106.2), grain yield (5.57 t ha-1), straw yield (6.26 t ha-1) and harvest index (0.47%) were found by transplanting 40 day old seedlings. The highest shoot weight (0.53 gm-2), 1000 grain wt. (25.3g) was found by transplanting 35 day old seedlings and 30 day old seedlings produced highest sterile spikelets (28.9) and panicle length (23.8 cm). Nitrogen rate in the nursery showed significant differences for shoot weight, root weight, survivor, plant height, total tillers hill-1, effective tillers hill-1, non-effective tillers hill-1, panicle length, grains panicle-1, grain yield and straw yield. Application of 50 kg N ha-1 gave higher plant height (108 cm) and harvest index (0.47%). On the other hand, application of 75 kg N ha-1 produced highest non–effective tillers hill-1 (1.0), grains panicle-1 (100.7), 1000 grain weight (25.3 g) and harvest index (0.47%). Application of 100 kg N ha-1 gave highest total tillers hill-1 (7.85), effective tillers hill-1 (6.85), non–effective tillers hill-1 (1.0), survivor (90.5%) and grain yield (5.01 t ha-1). Application of 125 kg N ha-1 gave highest panicle length (23.75 cm), grains panicle-1 (100.7), non–effective tillers hill-1 (1.0) and sterile spikelets (30.1). Forty day old seedlings grown with 100 kg N ha-1 at nursery found to be better in respect of grain yield. The result of the experiment also showed that aged seedlings regenerated quickly after desubmerge of water.Res. Agric., Livest. Fish.2(2): 261-269, August 2015
