An experiment was carried out to investigate the effect of different levels of Zn (0, 5, 10, 15kg/ha) on growth and yield of direct seeded and transplanted rice (Oryza sativa) under naturally salt-affected soil having pH=8.32; ECe=6.41dS/m; SAR=26.71(mmolc/L)½ at the farm of Soil Salinity ResearchInstitute, Pindi Bhattian during 2013. Plant height, number of tillers/plant, panicle length and number ofgrains/panicle were higher in transplanted rice than direct seeded rice at all Zn levels. Maximum paddyyield (2.61 t/ha) of direct seeded rice was attained with the application of 10 kg Zn/ha closely followedby 15 kg Zn/ha application (2.41 t/ha) which was statistical at par with paddy yield (2.45 t/ha) of transplantedrice in salt-affected field. However, overall paddy yield of direct seeded rice was 5 % higher than thetransplanted rice.

Diallel crossing is a method that is widely used to determine the ability to combine each individual so that it can identify the potential elders to be used in crossbreeding programs to assemble high yielding varieties. This experiment aims to determine the combining power of dialelic crosses of several varieties of rice using the Griffing II method, carried out in the experimental field of the Faculty of Agriculture, Mataram University in Nyiur Lembang Village, Narmada District, West Lombok Regency, from February to July 2019. This experiment uses the method experiments carried out in the field. The materials used in this experiment were four parents, namely IPB 3S variety, Situ Patenggang variety, Inpari 32 and G11 strain and the phenotype of the cross between the four parents. The experimental results showed that the effects of general affinity and special affinity for all observed characters (plant height, number of productive tillers, number of non-productive tillers, panicle length, number of filled grain, number of empty grain and weight of 100 grains) were significantly different, except on the effect of general affinity for the number of non-productive tillers showed no significant difference. The results of the combined power analysis of the four elders were positive, so it can be said that the four elders would get good results when crossed with a number of other genotypes.

ABSTRACT The purpose of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the salibu method, and to get the best concentration of gliricidia liquid organic fertilizer  (POC) on the growth and production of lowland rice. Field research has been conducted in Tababo Village, Subdistrict of Belang, district of Southeast Minahasa. The treatment in the experiment consists of one treatment factor, that were concentrations of gliricidia POC, ie  : 0, 50 , 100, 150, and 200 ml/litre. The results showed that gliricidia POC  have an effect on plant height, the number of  grain/panicle, and the dry grain yield (GKP) / plot, but not affect the number of productive tillers and weight of 1,000 grain. The best results were achieved in gliricidia POC concentration 200 ml/litre  with the highest values were: plant height was 98.93 cm; 116.420 grain/panicle; and 8.300 kg dry grain yield or equivalent to 6.92 ton/ha.Keywords : gliricidia POC, production, lowland rice,  salibu method

Over The Top

Levels of MSMA (monosodium methanearsonate) that simulated drift (0.2, 0.39, and 0.78 kg/ha) were applied over-the-top to rice (Oryza sativaL. ‘Vista’, ‘Starbonnet’, or ‘Labelle’) after flooding at four developmental stages between early tillering and late jointing. The MSMA rates used were equivalent to, or lower than, the 0.78-kg/ha rate that would be applied as an over-the-top application to cotton (Gossypium hirsutumL.) for early season weed control. Over-the-top applications of MSMA did not affect heading and maturity dates of filled grains regardless of the rate or application timing. Reductions occurred, however, in plant height, number of panicles, and yield. In addition, the percentage of erect panicles showing typical “straighthead” symptoms increased. Rice sensitivity to MSMA depended on MSMA rate and stage of growth with injury being most severe as rice approached the reproductive stages of development. Because aerial applications of MSMA to cotton are normally made before rice reaches the reproductive stage, injury resulting from MSMA drift should be minimal.

Boro Rice

A field experiment was conducted at Kalikapur village of Kaliganj upazila under Satkhira district in order to observe the effects of flooding duration and additional application of K and S on transplanted boro rice cv. Binadhan-8 during January - May 2013. The experiment was laid out in a split-plot design where the main plots comprised of five flooding levels viz. continuous flooding (W1), flooding for 10 days (W2), flooding for 20 days (W3), flooding for 30 days (W4), flooding for 40 days (W5), and the sub-plots of four additional (over the recommended dose) nutrients rates viz. S43 + K25 (T1), K38 (T2), S32 + K38 (T3), and K50 (T4), with three replications. The duration of flooding showed significant positive effect on the yield and yield components of boro rice cv. Binadhan-8. The highest values for plant height (106.8 cm), panicle length (28.4 cm), number of plants hill-1 (15.3), grain yield (4.8 t ha-1) and straw yield (6.5 t ha-1) were recorded in continuous flooding (W1) while these values were decreased with the decrease in the duration of flooding from 40 days to 10 days. Additional application of K and S also significantly influenced all of the parameters. Results revealed that the highest values for plant height (102.8 cm), panicle length (26.6 cm), plants hill-1 (15.4), 1000-grain weight (23.9 g), grain yield (4.8 t ha-1) and straw yield (6.1t ha-1) were obtained from T3 where S and K were applied @ 32 and 38 Kg ha-1 in addition to the recommended fertilizer rate. The interaction of flooding and nutrients significantly manipulated the yield and yield attributes. Due to interaction of flooding and nutrients, the highest growth and yield was observed in continuous flooding with S32 + K38 (W1T3). The results indicated that the flooding with fresh water and use of additional nutrients (K and S) had a remarkable effect in growing boro rice cv. Binadhan-8 in saline soils of Bangladesh.Res.

The research work was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during aman season from July to December 2015 to study the effect of nitrogen fertilizer and weed management on the growth and yield of transplant aman rice cv. BRRI dhan46. The experiment consisted of four fertilizer treatments viz. 0 kg N ha−1 (N0), 40 kg N ha−1(N1), 80 kg N ha−1(N2) and 120 kg N ha−1(N3) and four weeding treatments viz. one hand weeding at 20 DAT (W1), two hand weedings at 20 and 35 DAT (W2), three hand weedings at 20, 35 and 50 DAT (W3), weeding by Japanese rice weeder twice at 20 and 35 DAT (W4) and unweeded control (W5). The experiment was laid out in the randomized complete block design with three replications. The highest plant height (113.00 cm), number of total tillers hill−1 (8.74), number of effective tillers hill−1 (6.18), panicle length (21.98 cm), number of grains panicle−1 (114.20), grain yield (4.00 t ha−1), straw yield (5.25 t ha−1) and biological yield (9.25 t ha−1) were recorded in N2 (80 kg N ha−1) treatment. The lowest plant height (106.00 cm), number of total tillers hill-1 (7.20), number of effective tillers hill−1 (5.00), panicle length (20.70 cm), number of grains panicle−1 (97.60), grain yield (3.52 t ha−1), straw yield (4.46 t ha−1) and biological yield (7.97 t ha−1) were recorded from N0 (No nitrogen fertilizer control) treatment. On the other hand, the highest grain yield 4.23 t ha−1 was observed in three weedings condition because of the highest number of effective tillers hill−1 (6.81), number of grains panicle−1(111.10). The highest straw yield (5.51 t ha−1) was also found in three weeding condition. The lowest grain yield (3.40 t ha−1) was recorded in W5 (unweeded control) treatment. The lowest straw yield (4.31 t ha−1) was also observed in W5 (unweeded control) treatment because of the smallest plant (106.97 cm) and lower number of total tillers hill−1 (7.20). Therefore, 80 kg N ha−1along with three hand weedings at 20, 35 and 50 DAT may be used for obtaining the highest grain and straw yields of BRRI dhan46J. Bangladesh Agril.
