A large scale demonstration was taken on direct seeded rice in four locations (one at ARS, and three at Farmers field in 50 acres each) in and around the Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka. Our analysis showed that, the yield performance of direct seeded rice (DSR) varied with transplanted rice (TPR) and with different locations. This may be due to variety used and crop management practices adopted by the farmers. In L2, maximum grain yield was recorded in DSR (6500 kg/ha) and TPR (6200 kg/ ha) compared to other three locations. Further, the grain yield was higher in DSR compared to TPR in all the locations. Similarly, economics of DSR varied with TPR and with different locations. This may be due to yield variation at different locations. In L2, net returns and B:C ratio were higher in DSR (` 93628/ha and 3.93, respectively) and TPR (`79868/ ha and 3.0, respectively) compared to other three locations. Further, net returns and B:C ratio were higher in DSR compared to TPR. Further, 47% of the labour requirement was saved in DSR compared to TPR. Therefore, concluded that, farmers can grow rice by direct seeding instead of planting to save the labour and the expenditure.

A field experiment was conducted at Regional Agricultural Research Station, Parwanipur in 1998/99 and 1999/00 with an aim to find out the alternate management practices to compensate the loss in the grain yield due to flood. Irrespective of the varieties and transplanting dates, age of seedlings had no effect on grain yield of rice. But transplanting dates had significant effect on grain and grain contributing characters. The yield of rice transplanted at 1 Sept was 25.6 and 37.5% less in 1998/99 and 1999/00 respectively as compared to rice grain yield of 14 July transplanting. Radha 11 registered the highest grain yield of 4086 kg ha-1 in 1999/00 and 2662 kg ha-1 in 1998/99, which was at par to the yield obtained by Sabitri at the same year. The interaction effect of the age of seedlings, transplanting dates and varieties were found significant in both the years. 25 days old seedlings transplanted on 14 July in 1999/00 of rice varieties Masuli and Radha 11, produced statistically the similar yield. Radha 11 was the best among the tested varieties. 25 days old seedlings of Masuli, Basmati, Sabitri and Radha 11 can be recommended to transplant as late as Sept 1 .Key words: Age of seedlings; Rice; Transplanting datesDOI: http://dx.doi.org/10.3126/narj.v4i0.4858Nepal Agriculture Research Journal Vol. 4&5, 2001/2002Page: 14-17Uploaded date: 7 June, 2011

Background: Blackgram is an important crop among kharif pulses and is usually grown on marginal and sub-marginal lands without proper weed management under rainfed situation. Broad bed furrows had greater influence on plant growth over farmers practice. Weed management through mechanical or manual is normally tedious, labour consuming and costlier. Keeping this in view, the present study was envisaged to investigate integrated effect of land configuration and weed management regimes on productivity of urdbean. Methods: A field experiment was carried out during kharif seasons of 2016 and 2017 at Regional Agricultural Research Station, Lam, Guntur on effect of land configuration and weed management on performance of urdbean (Vigna mungo L.Hepper). The treatments included two land configurations i.e., flat bed and broad bed furrow method allotted as horizontal plots and four weed management practices i.e., weedy check, pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE, imazethapyr 10% SL @ 55 g ha-1 at 15-20 DAS and pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS allotted as vertical plots replicated four times in a strip plot design. The comparison of treatment means was made by critical difference (CD) at P less than 0.05 by using standard statistical procedures. Result: Based on the results, it can be concluded broad bed method of land configuration proved its superiority over flat bed method by producing 12.8 per cent higher grain yield besides empowering growth and yield attributes. Among the weed management practices, the highest grain yield (1280 kg ha-1) recorded with pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS along with maximum monetary returns and B:C can be recommended for urdbean.

Two-year field experiment was conducted during rainy (kharif) seasons of 2015 and 2016 at ICAR-Indian Agricultural Research Institute, New Delhi to evaluate the effect of potassium (K) fertilization on growth indices, yield attributes and economicsof the dry direct seeded basmati rice. Application of recommended dose of K (60 kg ha-1) half at basal and remaining half at panicle initiation increased the grain yield (5.4 tha-1), net returns (Rs. 85,000 ha-1) and B: C (1.8) ratio by 10, 16 and 20% respectively, over applying the entire amount of K as basal. Significant positive correlation was observed between yield attributes [total tillers(r2=0.74), effective tillers m-2(r2=0.79)]and grain yield of dry direct seeded basmati rice. The two foliar sprays (1st spray at active tillering, 2nd spray at panicle initiation) of 2.5% potassium nitrate (T6) increased fertile tillers % (93.8%), fertility % (83.5%) and grain yield (4.3 t ha-1) by 5%, 6% and 8% respectively, over T1 (control). In case, K is not available for top dressing then two foliar sprays of 2.5% KNO3 at active tillering and panicle initiation stage is found optimum to obtaining higher net returns (Rs. 85200 ha-1) and return from investment on K (Rs. 19.9 rupee-1). Insufficient supply of K during active tillering and panicle initiation stage, decreased the production of tillers m-2 and conversion of tillers into fertile tillers respectively. Hence, active tillering and panicle initiation stage are most critical for K supply in dry direct seeded basmati rice.

Direct seeded rice is a boon to farmers where the water release from the reservoir is delayed. Nitrogen fertiliser management is one of the strategies bto rectify the nutrient-related issue in Direct seeded rice. The present study aimed to optimize the nitrogen dose for direct-seeded rice in the new and old Cauvery delta zone of Tamil Nadu. Field experiments were conducted during kuruvai and samba seasons at Tamil Nadu Rice Research Institute, Aduthurai and Agricultural research station Thanjavur representing old and new Cauvery delta regions during 2019-20 and 2020-21. Totally from eight experiments, the results of four field experiments in each location revealed the highest grain yield in the treatment T6 -application of 150 kg Nha-1 (5596kg/ha) which was statistically on par with treatment T5 -125kg N/ha (5326 kg/ha) in old delta and new delta. The higher grain yield was recorded in the T6 (5140 kg/ha), statistically on par with T5 (4550 kg/ha). The higher available nitrogen content of 312 kg/ ha,292 kg/ha was recorded for N application @ 150kg/ha, which was statistically on par with  309 kg/ha and 289 kg/ha, respectively, both the kuruvai and samba seasons for N application of 125 kg/ha. In the new CDZ, the same trend was followed as that of the old delta. Based on economics, N applied @125 kg/ha recorded a higher BC ratio for direct-seeded rice. For the benefit of farmers of both deltaic regions, the nitrogen application of 125 kg ha-1 for direct-seeded rice is recommended.

AbstractThe experiment was conducted at the Regional Agricultural Research Station, BARI, Ishwardi, Pabna, Bangladesh, during 2013-2014 and 2014-2015 to introduce maize as relay crop with T. Aman rice under different agronomic practices for determine the production potentials. The experiment was design split plot with three replications. The agronomic management practices included four plant spacing viz. S1=75 cm×20 cm (66666 plants/ha), S2=60 cm×20 cm (83333 plants/ha), S3=50 cm×20 cm (100000 plants/ha) and S4=40 cm×20 cm (125000 plants/ha) and four soil management practices viz. M1=soil mulching at 25 DAE, M2=earthing up at 25 DAE, M3=straw mulching at 25 DAE and M4= without earthing up and mulching (control). Seeds were relayed by dibbling manually in 10 days before the harvest of T. Aman rice. Results showed that an increasing plant spacing increased leaf area Index (LAI), total dry matter (TDM), crop growth rate (CGR) and light energy interception (LEI). Grain yield was higher in S3spacing (8.44 t/ha) than others (S48.11 t/ha, S27.34 t/ha and S16.89 t/ha). Among the soil management practices, M2increased LAI, TDM, CGR, LEI as well as grain yield. Moreover, M2and M1gave similar grain yield (8.22 t/ha and 8.02 t/ha), that were significantly greater than other two soil management practices (M37.55 t/ha and M46.98 t/ha). From the economic point of view, combination of S3M1gave better performance with gross margin of Tk. 95000/ha and BCR of 2.17. On the basis of results, S3M1combination was suitable for growing maize under relay sowing with T. Aman rice.

Background: Bio-fortification, the process of integrating nutrients into food crops, provides a sustainable and economic way of increasing the density of micronutrients in important staple crops. Agronomic bio-fortification is the easiest, practicable and fastest way for bio-fortification of pulse grains with Fe, Zn, or other desirable micronutrients. Increasing micronutrient rich foods and improving dietary diversity will substantially reduce micronutrient disorders.Methods: A field experiment was conducted during the post rainy seasons of 2015, 2016 and 2017 at Zonal Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur (Karnataka) to know the effect of soil and foliar fertilization of Zn and Fe on chickpea genotypes. Two genotypes (Annigeri 1 and JG 11) and six fertilization treatments (Control, 0.5% Zn, 0.1% Fe, Zn + Fe, seed treatment with 2 g Zn kg-1 seeds and soil application of Zn) were tested in medium black soils in split plot design with three replications.Result: The pooled data of three seasons indicated that the genotype JG 11, performed better than Annigeri 1 in terms of seed yield (1309 kgha-1), net returns (₹ 31634ha-1) and B: C ratio (2.52). On biofortification of Zn and Fe, foliar fertilization of Zn @ 0.5% + Fe @ 0.1% at flowering stage recorded significantly higher grain yield (1321 kgha-1), net returns (₹ 31179ha-1) and B: C ratio (2.44) over rest of the treatments. Further, foliar fertilization of Zn + Fe had significant influence on nutrient concentration (Zn and Fe) in chickpea grains. Thus, it could be concluded that combined biofortification of Zn + Fe to chickpea crop could be the viable agronomic intervention for getting higher productivity and nutritional security.

This experiment was conducted using a randomized complete block design with three replications at Field Crops Research Station, Abu-Graib, Office of Agricultural Research, during 2011-2012 and 2012-2013. The results revealed significant differences among genotypes for the studied characters at both seasons. The best genetic/environmental variance ratio attained for spike length (11.90) and no. of spikes. m-2 (9.22) in the first season, and grain yield (8.82) then harvest index (4.87) in the second season. High GCV observed for grain yield (15.68), no. of spikes. m-2 (15.18) in the first season, and harvest index (16.89) and grain yield (14.22) in the second season. High heritability estimates associated with high genetic advance for no. of spikes. m-2, in the first season. While, moderate h2bs estimates associated with high GA for same trait in the second season. Expected response to selection ranged from 0.93 to 84.6, also selection index ranged from 1.23 to 106.44 for grain yield and number of spikes. m-2, respectively in the first season also the same pattern was observed for value of second season. Characteristics like no. of spikes. m-2, plant height, no. of grains. Spike-1 and grain weight showed high heritability coupled with high genetic progress. Therefore, these characters should be given top priority during selection breeding in durum wheat.
