A 2-year field experiment was conducted to assess system productivity, nutrient use efficiency and apparent balances of phosphorus (P) potassium (K) in diversified rice-based cropping systems at Gazipur, Bangladesh. Four systems: wheat–fallow–rice, maize–fallow–rice, potato–fallow–rice mustard–fallow–rice main plots four combinations: NPK, NK, NP PK sub-plots were arranged a split-plot design with three replications. Receiving the NPK treatment, all component crops gave highest yield,...

Moisture is a significant component in cotton growth and yield, but stress the main factor limiting crop productivity since it has negative impact on cotton's ability to produce high-quality fiber as well square/boll lint output. Reduced water availability during development of bolls could lead drastically decreased yield. Four genotypes (MNH-1020, FH-114, BH-178 CIM-602) were grown under regular irrigation water-deficit circumstances examine tolerance scarcity. To further understand impacts...

Genotypic variations plant height, leaf area index, its distribution, crop growth rate seed yield were observed. height ranged 40.33 63.17 cm, index varied 3.01 8.13 75 days after emergence, total...

Spatial variability of soil chemical properties is critical for improving rice productivity and sustainable farming techniques. However, a systematic assessment on the spatial tidal ecosystem has not been conducted. So, 144 samples were collected across Barisal, Borguna Jalkhati districts analyzed six common properties. Rice yield data was obtained by surveying farmers during crop harvest. Soil parameters varied considerably throughout study areas their coefficients variation ranged from...

A field experiment was conducted in the rabi (dry) season of 1998–99 on a clay terrace soil Bangladesh, order to study effects irrigation and potassium (K) fertilization yield, total water use, use efficiency radish. Both K application were found be indispensable for increasing yield radish, due their individually significant impact yield. The interaction effect insignificant, but highest 30.1 Mg ha−1 obtained under levels (four irrigations with 160 kg K2O ha−1) as positive both treatments...

In tidal submergence ecosystem, nitrogen (N) is a crucial nutrient for improved and sustainable rice production. Therefore, series of on-farm on-station field experiments were conducted to develop suitable N management practice tolerant landrace aman rice. on-farm, urea deep placement (UDP) through super granule before panicle initiation (PI) stage was compared with no fertilizer application. Similarly, five practices viz. (i). two splits prilled (PU), (ii). UDP at 10 DAT, (iii). PI, (iv)....

The field experiment on the long-term application of organic residues was started in 1988 at farm Bangabandhu Sheikh Mujibur Rahamn Agricultural University (BSMRAU; named as Institute Postgraduate Studies Agriculture (IPSA) until 1998) and is continued now.Five kinds (n( application, rice straw, green manure, compost, cowdung) were applied every June to cover soil surface uniformly a thin layer incorporated into depth 10cm.Rice (July October) wheat (mid-November or December March) have been...

An on farm field experiment was conducted to evaluate locally improved aman rice varieties in terms of nitrogen use efficiency and grain yield southern region Bangladesh. The treatments were: i. deep placement urea (UDP) before panicle initiation stage ii. farmers’ practice (FP/control). popular were used as planting materials. Higher panicles m-2 grains panicle-1 obtained from UDP application compared FP. Nitrogen fertilization increases straw content significantly. Application gave...

Combining ability effects were estimated for grain yield and some other important agronomic traits of maize in a 7×7 diallel analysis excluding reciprocals. The variances general combining (GCA) found significant yield, days to pollen shedding, silking ear height while it was non-significant plant number kernels/ear. Non-significant variance kernels/ear indicates that these two predominantly controlled by non- additive type gene action. Specific (SCA) all the characters except silking....
