An experiment was conducted at the research field of Horticulture Research Centre, BARI, Gazipur during Rabi season of 2012-13 to 2014-15 to evaluate the response of different doses of N, P and K on the yield and yield attributes of chrysanthemum (var. BARI Chrysanthemum-1) and to find out the optimum and economic doses of NPK for maximizing yield of chrysanthemum. Treatments comprising four levels each of N (0, 100, 150 and 200 kg ha-1), P (0, 50, 75 and 100 kg ha-1) and K (0, 90, 135 and 180 kg ha-1) along with blanket dose of 2 kg B and 4 kg Zn ha-1 were used. The treatments were assigned in a randomized complete block design with three replications. The combined effect of NPK significantly increased yield and yield attributes of chrysanthemum for each of the yearly experiments as well as the average of three years results. Significantly, the highest flower yield (12.45, 11.47 and 11.96 t/ha) was obtained with the application of N150P75K135 kg ha-1 (T3) along with blanket dose of 2 kg B and 4 kg Zn ha-1 for the years of 2012-13, 2013-14 and 2014-15, respectively and it was statistically identical with T4 (N200P75K135 kg ha-1) treatment. Application of 150 kg N, 75 kg P and 135 kg K increased yield by 52.76, 42.29 and 36.51%, 152.08, 126.23 and 99.13% and 88.35, 51.30 and 60.75%, respectively, over their control in respect to the years. The highest benefit-cost ratio 5.54 followed by 5.14 was obtained from T3 (N150P75K135 kg ha-1) followed by T4 treatment, respectively. From the quadratic regression equation averaging three years data the optimum and economic doses 155 and 151.8 kg N, 79.3 and 77.68 kg P and 118.75 and 115.7 kg K, respectively were found which could be recommended for chrysanthemum production in Grey Terrace Soil of Joydebpur under AEZ 28.The Agriculturists 2017; 15(1) 58-67

BARI Marigold-1) to different doses of N, P and K fertilizers and to find out the optimum and economic doses of NPK for maximizing flower yield. Eleven treatments as T1, T2, T3, ……,T10 and T11 comprising with four levels of fertilizer nutrients each of N (0, 60, 90 and 120 kg ha-1), P (0, 30, 40 and 50 kg ha-1) and K (0, 60, 90 and 120 kg ha-1) along with a blanket dose of 2 kg B and 4 kg Zn ha-1. The experiment was conducted assigning the treatments in a randomized complete block design with three replications. Flower yield and yield attributes of marigold significantly increased with NPK fertilizer for all three years. The significantly highest flower yield (22.25, 27.38 and 25.15 ton ha-1) was obtained from T3 treatment applying the nutrients N90P40K90 kg ha-1 along with blanket dose of 2 Kg B and 4 kg Zn ha-1 for the years 2012-13, 2013-14 and 2014-15, respectively which was statistically identical with T4 treatment (N120P40K90 kg ha-1) for the year 2012-13, but significantly different from all other treatments for the years 2013-14 and 2014-15, respectively. Flower yields were increased in T3 treatment (N90P40K90 kg ha-1) by 81.34, 62.53 and 49.53%; 146.00, 119.39 and 108.84% and 121.20, 92.13 and 84.11% over their control in respect to the years 2012-13, 2013-14 and 2014-15. The highest benefit-cost ratio 7.14 was obtained from T3 (N90P40K90 kg ha-1) followed by T4 (6.53) treatment. From the quadratic regression equation averaging three years data the optimum and economic doses 103.75 and 102.44 kg N; 36.67 and 36.31 kg P and 90.10 and 88.43 kg K, respectively were found which could be recommended for marigold production in Grey Terrace Soil of Joydebpur under AEZ 28.The Agriculturists 2017; 15(1) 101-109

Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

A field experiment was carried out to study the “Effects of different maize–soybean intercropping patterns on yield attributes, yield and B: C ratio” at the Agricultural Research Farm, Bhagwant University, Ajmer. Treatment consists of Sole maize (60x20 cm), Sole Soyabean (30x10 cm), Maize-Soybean (1:1) (60X20 cm), Maize-Soybean (1:1) (75X20 cm), Maize-Soybean (1:1) (90X20 cm), Maize-Soybean (1:2) (90X20 cm) and Maize-Soybean (2:6) (Paired row 45/180 cm). There were four replicated blocks and plot sizes measuring 7 m x 4.5 m laid out in a randomized complete block design (RCBD). Results of the experiment showed that the maize-soybean intercropping patterns had significant effect on maize stover and grain yields. Sole maize recorded significantly higher yield than intercropped maize under varying geometry and row proportion. However, it was at par with maize intercropped with soybean in 1:1 row proportion with 60 x 20 cm .The intercropping patterns affected significantly the PAR intercepted and the leaf area index. The soybean sole crop intercepted significantly more light and leaf area index (LAI) than all other treatments and/or crop. Further,, the yield of sole soybean was significantly superior over other intercropped treatments. The highest benefit cost ratio revealed that higher return per unit money invested for inputs used for raising crops. The highest B: C ratio was recorded with maize + soybean in 2:6 paired row (3.57) intercropping system. The least B: C ratio was recorded in sole soybean (2.45).

A field experiment was conducted at S.V. Agricultural College farm (ANGRAU), Tirupati, India during rabi, 2009-10. The experiment was consisted of five system treatments (sole maize at 60 x 20 cm sowing, sole maize in skipped row sowing, maize in skipped row + greengram, maize in skipped row + blackgram and maize in skipped row + cluster bean) and three nitrogen doses (100, 75 and 50% recommended dose of nitrogen). The treatment combinations were laid out in factorial randomized block design with three replications. Yield attributes and grain yield of maize were maximum with sole maize at 60x20cm spacing but at par with maize + cluster bean, maize + blackgram and maize + greengram intercropping system. The lowest parameters were observed with sole maize sown in skipped rows. All the parameters were maximum with the application of 100% recommended dose of nitrogen to maize, but comparable with that of 75%. The maize equivalent yield, land equivalent ratio and benefit cost ratio were higher with maize + cluster bean intercropping as compared to other treatments. The result revealed that among the different maize intercropping systems tested, maize in skipped rows + cluster bean with 75% recommended dose of nitrogen to maize was found economically profitable.SAARC J.

A field experiment was conducted at Punjab Agricultural University, Regional Research Station, Gurdaspur (Punjab) during kharif 2016-17, to study the effect of split application of potassium on yield and yield attributes of soybean. The experiment was conducted in randomized complete block design with seven treatments applied at sowing and as split application of potassiumT1: Recommended fertilizer dose (12.5 kg N, 32 kg P2O5and no potassium application) , T2: 15 kg K2O ha-1(at sowing), T3: 30 kg K2O ha-1(at sowing), T4:60 kg K2O ha-1(at sowing), T5: 7.5 kg K2O ha-1 (at sowing) + 7.5 kg K2O ha-1 (at flowering), T6: 15 kg K2O ha-1(at sowing) +15 kg K2O ha-1(at flowering), T7: 30 kg K2O ha-1(at sowing) +30 kg K2O ha-1(at flowering). Results revealed that significantly higher grain yield (25.2 q ha-1) was obtained in T7 (30 kg K2O ha-1 (at sowing) + 30 kg K2O ha-1 (at flowering) as compared to all other treatments but it was statistically at par with the split application of potassium @ 15 kg K2O ha-1 (at sowing) + 15 kg K2O ha-1 (at flowering) (T6) with grain yield of (22.6 q ha-1). Split application of potassium significantly increased soybean grain yield over the basal application with highest benefit cost ratio (7.1). Among the split application of potassium, grain yield of soybean was increased significantly by 15.6 % in T7 treatment over T5. Split application of potassium was more beneficial than applying full dose of potassium at the time of sowing due to higher number of pods and pod weight plant-1.

An on-farm trial was established at Saran district of Bihar, aiming to assess the different combinations of micro and secondary nutrients on yield and economic profitability of mustard (var. Rajendra suphalam). The experiment comprised three treatments i.e., T1: RD-S+Zn (Farmer practices), T2: RD-S+B and T3: RD-S+B+Zn and seven replications performed under a completely randomized block design during 2018-19. Results of the experiment revealed that combined application of sulphur, boron and zinc  significantly improved the number of seeds per siliqua: 37.2%, stover yield: 12.3% & seed yield: 33.3% over farmers practice (T1: RD-S+Zn). The highest seed yield and gross return in treatment T3: RD-S+B+Zn was well reflected in  the maximum net return (Rs. 40954.0 ha-1) and benefit-cost ratio (2.29). In conclusion, the combined application of sulphur, boron and zinc was performed better for mustard cultivation in the middle Indo-Gangetic plains of Bihar.

Magic growth solution along with prilled urea in the rice leaf as foliar spray may save urea compared to soil application of urea alone. In this regard, an experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University during Boro Season (December-April, 2015) to evaluate the effects of urea and magic growth spray solution on the yield and yield attributes of BRRI dhan29. The experiment consisted of ten treatments viz.,T1 = Control, T2 = 99 kg urea ha-1, T3 = 63 kg urea ha-1 + 2.16L ha-1 magic growth spray solution, T4 = 99 kg urea ha-1 + 5.66L ha-1 magic growth spray solution, T5 = 117 kg urea ha-1 + 1.44L ha-1 magic growth spray solution, T6 = 117 kg urea ha-1 + 5.66L ha-1 magic growth spray solution, T7 = 126kg urea ha-1 + 5.66L ha-1 magic growth spray solution,T8 = 132 kg urea ha-1, T9 = 132 kg urea ha-1 + 5.66L ha-1 magic growth spray solution, T10= 132 kg urea ha-1+ 2.16L ha-1 magic growth spray solution and laid out in a randomized complete block design (RCBD) with three replications. The results revealed that urea and magic growth spray solution exerted significant influence on the yield contributing characters and yield of BRRI dhan29 except panicle length, sterile spikelets and 1000-grain weight. The highest grain and straw yields (6.16 and 9.33 t ha-1, respectively) were obtained from T7 treatment which could be the resultant effect of highest number of effective tillers hill-1, highest number of grains panicle-1 and lowest number of sterile spikelets panicle-1. Grain yield was significantly and positively correlated with plant height, effective tillers hiil-1, panicle length and grains per panicle. Economic analysis showed that net return and benefit cost ratio (BCR) was the highest (1.41) in T7 treatment. Thus the overall results suggest that farmers may be advised to apply 126 kg urea along with 5.66L magic growth solution per hectare to produce economically highest grain yield of BRRI dhan29, under the agro-climatic condition of Bangladesh Agricultural University.Res.
