AbstractIntegrative use of organic and inorganic fertilizers not only fulfills the nutritional needs of crops, but also ensures sustainable production and environmental protection. Thus, this study was conducted to determine the influence of phosphorous application from integrated organic and inorganic fertilizers on maize. In this study poultry manure and press mud were integrated with single superphosphate (SSP) as the phosphorus source. Maximum amounts of time to 50% tasseling (47.75 and 47.63 days), 50% silking (53.07 and 53. 11 days) and maturity (106.47 and 106.49 days) were recorded where the recommended dose of phosphorus was applied from only inorganic sources. For application of phosphorus from integrated sources, the treatment containing 25% poultry manure + 75% SSP provided the highest number of grains per cob (459.60 and 460.70), 100-grain weight (26.85 and 27.82), stover yield (9.61 and 10.41 t ha-1), grain yield (7.14 and 7.82 t ha-1) and grain protein content (8.59 and 8.63%) during both years. However, all treatments had non-significant effects on grain oil and starch content. Moreover, in given years, the integrated use of 75% poultry manure and 25% SSP resulted in a maximum benefit-cost ratio of 2.97 and 3.11 USD, respectively, as compared to integrated use of 25% poultry manure and 75% SSP, which produced a benefit-cost ratio of 2.58 and 2.81 USD. In conclusion, integration of organic sources with inorganic phosphorus substantially improves the yield and economics of hybrid maize.

AbstractA field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

The experiment was conducted at farmer’s field in Bandarban sadar areas daring rabi season 2004-05 and 2005-06 to find out the feasibility and profitability of growing short duration vegetables i.e., Potato (var. Heera,), lalsak (var. Red king,), spinach (var. local), and French bean (var. BARI Jharseem-2) with hybrid maize (var. Pacfic-11). The grain yield of sole maize was 9.65 t/ha whereas yield reduction was found in intercrop situation The maize equivalent yield showed that maize + spinach produced significantly higher yield (15.62 t/ha) followed by maize + lalsak (14.48 t/ha) and maize + potato (13.93 t/ha). Maize + spinach recorded the highest gross margin (Tk. 86,257/ha), but higher benefit cost ratio and marginal rate of return was accounted from maize + lalsak combination. The lowest gross margin was obtained from sole maize. It revealed that the combination of maize with lalsak or spinach were more compatible and profitable intercropping system in hill valleys of Bandarban areas.

An experiment was conducted in charland at the Multi Location Testing (MLT) site Bhuapur, Tangail during 2012-13 and 2013-14 under AEZ-8 to find out the suitable intercropping system of hybrid maize with different short duration vegetables with economic return. The experiment was laid out in RCB design with six dispersed (six farmers’ field) replications. The hybrid maize (ver. BARI Hybrid maize-7), potato (Diamant), spinach (local), red amaranth (BARI Lalsak-1), Radish (BARI Mula-1) were used as the planting materials. Five treatment combinations viz. T1= Sole Maize, T2= 100% Maize (maize paired row) + Potato (var. Diamant), T3= 100% Maize (maize paired row) + Spinach (var. local), T4= 100% Maize (maize paired row) + Red amaranth (var. BARI Lalshak-1) and T5= 100% Maize (Maize paired row) + Radish (var. BARI Mula-1) were studied. Maize grain yield in intercropped combination varied from 5.59-7.62 t ha-1. But the highest grain yield (8.17 t ha-1) was obtained from sole maize. Maize equivalent yields in the intercrops situation ranged from 11.39-19.68 t ha-1 where highest maize equivalent yield 19.68 t ha-1 was recorded from the treatment T3 (100 % maize + spinach). The same combinations also gave highest gross return (Tk. 373930 ha-1) and gross margin (Tk. 258585 ha-1) as well as benefit cost ratio (3.24). Though highest grain yield was recorded from sole maize but equivalent yield and economic return was much lower than the treatment T3.Bangladesh Agron. J. 2015, 18(2): 65-69

The experiment was conducted at the research field of Agronomy Division, BARI, Joydebpur, Gazipur and ARS, Burirhat, Rangpur during consecutive two years of 2009-10 and 2010-11 to find out optimum fertilizer dose for hybrid maize-mukhikachu relay cropping system. Five fertilizer combinations viz, Recommended fertilizer of hybrid maize (RFM) + 112 kg N/ha, RFM + 25% recommended fertilizer of mukhikachu (RFK), RFM + 50% RFK, RFM + 75% RFK and RFM + 100% RFK were tested on hybrid maize-mukhikachu relay cropping system. Sole crops of hybrid maize (cv. BARI Hybrid Maize-5) and mukhikachu (cv. Bilashi) with their respective recommended fertilizer dose (maize: 255-55-140-40-6-2 kg/ha NPKSZnB and mukhikachu: 112-32-95-22 kg/ha NPKS) were included for comparison. Grain yield of sole maize with recommended fertilizer practice was identical with other fertilizer combinations at both the locations. Yield and yield components of mukhikachu under different fertilizer management practices increased with the increase of fertilizer levels up to RFM + 50% RFK and then decreased at both the locations. Edible yield of sole kachu with recommended fertilizer practice was the highest but it was identical to RFM + 50% RFK at both the locations. The highest maize equivalent yield (Joy: 24.26 t/ha, Buri: 31.56 t/ha) and gross return (Joy: Tk 291120/ha, Buri: Tk 378720/ha) was recorded in RFM + 50% RFK. But the highest gross margin (Joy: Tk 207035/ha, Buri: Tk 291570/ha) was obtained from RFM + 25% RFK at Joydebpur and from RFM + 50% RFK at Burirhat. The highest benefit cost ratio (Joy: 3.69, Buri: 4.64) was found from RFM + 112 kg N/ha at both the locations. The results revealed that recommended fertilizer dose (255-55-140-40-6-2kg/ha NPKSZnB) of hybrid maize plus 112 kg N/ha (extra) might be economically profitable for hybrid maize mukhikachu relay cropping system at both the locations.

An intercropping experiment was conducted on hill valley at Hill Agricultural Research Station, Ramgarh and Kharachari during two consecutive rabi seasons of 2012-13 and 2013-14 to select suitable local bush bean cultivar for intercropping with hybrid maize in hilly areas of Bangladesh. Seven intercropping treatments viz., T1 = Normal maize spacing (75 cm × 25 cm) + 2 rows black seeded bush bean,T2 = Normal maize spacing (75 cm × 25 cm) + 2 rows pink seeded bush bean,T3 = Maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows black seeded bush bean,T4 = Maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows pink seeded bush bean, T5 = Maize wider spacing (100 cm × 50 cm) with 2 plants/hill + 3 rows black seeded bush bean, T6 = Maize wider spacing (100 cm × 50 cm) with 2 plants/hill + 3 rows pink seeded bush bean and T7 = Sole maize spacing (75 cm × 25 cm) were used. Sole hybrid maize produced the highest grain yield at both the locations. Bush bean cultivars in intercropped situation depressed hybrid maize yields by 7.15-37.29% at Ramgarh and 2.56-37.51% at Khagrachari compared to sole hybrid maize. The highest maize equivalent yield of 23.10 t/ha at Ramgarh and 24.08 t/ha at Khagrachari was recorded in maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows pink seeded bush bean combination (T4). The same treatment also showed the highest gross return (Tk 277200/ha at Ramgarh and Tk 288960/ha at Khagrachari), gross margin (Tk 180050/ha at Ramgarh and Tk 191810/ha at Khagrachari) and benefit cost ratio (2.85 at Ramgarh and 2.97 at Khagrachari). The result revealed that maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows pink seeded bush bean could be suitable and economically profitable for hybrid maize and bush bean intercropping in hill valleys of Bangladesh.Bangladesh J.
