The major cropping pattern in the South-western coastal area of Bangladesh is transplanted aman rice followed by fallow during the rabi season (November to March) and kharif-I (April-July) season. Crop production during rabi season is limited due to various ecological factors including soil salinity, lack of fresh irrigation water, short winter period, late harvest of previous aman rice, heavy clay soil etc. Tomato is a popular winter crop in that area which is mainly cultivated around homestead and ridges of fish pond, where soil salinity and tillage is not a major problem. An attempt was taken to grow tomato in Khulna district of Bangladesh after T. Aman rice harvest during 2018–19 in order to investigate tomato performance at different mulch materials and Nitrogen sources. The two factors experiment was carried out in randomized complete block design with three replications. Mulch materials viz. rice straw (M1), black polythene (M2) and no mulch (M3) were employed as factor one and nitrogen source viz. prilled urea (N1) and urea super granule (N2) were assigned as factor two. Results showed that there was no interaction effect of mulch and nitrogen treatments. Single effect of mulch and nitrogen treatments showed that highest fruit yield was found from rice straw (M1) (17.32 t ha−1) and prilled urea (N2) (15.64 t ha−1), respectively. So, tomato can be grown with rice straw mulch along with prilled urea for higher economic return (MBCR 2.24).

SUMMARYNitrogen efficiency from Azolla microphylla or Sesbania rostrata green manure, rice straw, and inorganic fertilizer-N was compared in two long-term experiments with irrigated lowland rice (Oryza sativa L.). Treatments included a control and each nitrogen source alone or in combinations that provided 50% of the total applied nitrogen from an organic and inorganic nitrogen source. All nitrogen sources were applied at equivalent nitrogen rates to 19–22 consecutive rice crops. Residual effects were assessed in two subsequent cropping seasons at one site. Lower grain yield, agronomic efficiency (Δgrain per kg total applied nitrogen), and apparent nitrogen uptake were obtained from green manure and rice straw nitrogen as sole or dual nitrogen sources rather than from a standard split application of prilled urea. Compared to prilled urea, residual effects from green manure or rice straw included a significant increase in soil organic carbon and total nitrogen, and greater extractable soil nitrogen in the vegetative growth period. After panicle initiation there was no residual effect on the rate of crop nitrogen accumulation, and final grain yields were similar regardless of previous nitrogen source. Recycling of rice straw appeared to have greater potential for reducing fertilizer-N requirements than use of green manure because rice straw is often a wasted resource in irrigated rice systems of the humid tropics, the efficiency of rice straw nitrogen in combination with prilled urea is comparable to green manure nitrogen, and the increase in soil nitrogen from rice straw was 50–150% greater than from green manure.

An experiment was carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

Corn (Zea mays L.) is a common food and feed product in the community since it is commonly used as rice substitution as food staple. Fertilizer application is required to attain crop high yields. Plants can receive nutrients from synthetic nitrogen fertilizers (NF) during their growth cycle. However, excessive use of NF might harm the environment. Organic chicken manure (CM), on the other hand, can minimize the harmful impact of NF. Chicken manure benefits to improve the soil’s physical, chemical, and biological properties. To boost maize plant growth and productivity, might employ CM and NF. The objective of this study was to determine the effect of NF and CM on corn growth and yield. This research was conducted in Kembang Seri, Central Bengkulu, Indonesia from November 2019 to February 2020 using Randomized Complete Block Design (RCBD) with two factors and three replications. The first factor was NF doses (100, 125, and 150 %), and the second-factor consisted of CM doses (0, 10, and 20 tons/ha). Data were analyzed using ANOVA F-5%. On shoot dry weight of corn cultivated in a double row cropping pattern, there was an interaction between the dose of N and chicken manure. At 0 tons/ha, the optimum N fertilizer dose for chicken manure is 135.96 %, or 407.86 kg urea/ha. At a dose of 20 tons/ha, the optimum N fertilizer dose for chicken manure is 141.22 %, or 423.65 kg urea/ha. In a double row cropping pattern, different nitrogen fertilizer doses had no effect on corn growth and yield. The optimal dose of chicken manure was 16.65 tons/ha for plant height, 17.35 tons/ha for stem diameter, 18.89 tons/ha for leaf greenness, 17.35 tons/ha for cob length, 15.01 tons/ha for cob weight, 18.87 tons/ha for dry seed weight/plant, and 19.74 tons/ha for dry seed weight/plot.

An experiment was carried at Multi Location Testing site Barguna to determine suitable variety of mustard (Brassica species) for the late sowing condition for the coastal area of Bangladesh during rabi season of 1998-1999 and 1999-2000. Four varieties of mustard such as Daulat, Rai-5, Improved tory-7, and Ishurdi local with four sowing dates viz.15 Nov, 23 Nov, 30 Nov. and 7 Dec. were used for the experiment. The experiment was laid out in a split plot design with sowing date in the main plot and varieties in the sub plot. The results revealed that the variety Daulat (1035 kg/ha) and Ishurdi local (1014 kg/ha) produced identically superior yield irrespective of sowing time. 15 November (1164 kg/ha) and 23 November (1002 kg/ha) recorded identically superior yield irrespect of variety. Daulat and Ishurdi local variety sowing could be delayed up to 30 November to obtain a profitable yield of (872 kg/ha) and (940 kg/ha) respectively which was still economically profitable.
