The experiment was laid out in a randomized complete block design, with three replications and eight treatments including T1 (Control), T2 [HYG based 100% chemical fertilizer (CF)], T3 [CD + CF (IPNS basis)], T4 [CD slurry + CF (IPNS basis)], T5 [PM + CF (IPNS basis)], T6 [PM slurry + CF (IPNS basis)], T7 [TC + CF (IPNS basis)] and T8 [VC + CF (IPNS basis)]. Trichocompost + CF and vermicompost + CF containing treatments produced higher crop yield followed by poultry manure slurry and cowdung slurry. Integrated use of manures and fertilizers gave on an average 6.7-33.7%, 8.3-33.8% and 2.9-18.3% yield incr...

The Zn, Cu, Fe and Mn extracted by DTPA solution, both at pH 7.3 and also after adjustment to match the final soil pH, were measured by flame AAS. The same elements were determined in ammonium acetate extracts, for extractants buffered at pH 4.8, pH 7.0 or at the final soil pH. The effect of extractant pH upon the amounts of trace elements removed is discussed for the two extractants, with particular reference to Zn. The influence of soil pH upon the amounts of trace elements extracted is also considered. There appears to be a distinct relationship between rate of decrease of DTPA‐extractable Fe with increasing soil pH and the effect of pH upon DTPA‐extractable Zn, high rates of decrease of extractable Fe being associated ...

The study was conducted to evaluate the effect of lime and manure on soil fertility, nutrients and yields of wheat, mungbean and rice. Experiments were done at Agricultural Research Station (ARS), Bangladesh Agricultural Research Institute (BARI) farm and farmer field over two consecutive years with the cropping pattern, namely wheat-mungbean-transplanted (T.) aman rice/monsoon rice. The varieties used were Bijoy for wheat, BARI mung6 for mungbean and Bina dhan7 for T. aman rice. There were nine treatment combinations with three lime levels (0, 1 and 2 ton dololime ha-1) and three manure treatments (poultry manure, farmyard manure and no manure) with three replications. The rate of poultry manure was 3 t ha-1 and that of farmyard manure was 5 t ha-1. Nutrients from manure sources were supplemented wit...

Five Zn rates, i.e., 0, 1.5, 3.0, 4.5, and 6.0 kg ha−1 applied as ZnSO4·7H2O (23% Zn), and two wheat varieties, i.e., ‘BARI Gom-25’ and ‘BARI Gom-26,’ were used in the study. All plant characteristics, except 1,000-grain weight and plant height, i.e., tillers plant−1, spikes m−2, spike length, spikelets spike−1, and grains spike−1, were significantly influenced by Zn fertilization. Treatment with 3.0 kg Zn ha−1 (Zn3.0) produced the highest grain yield (3.90 t ha−1), which was statistically similar to Zn4.5 and Zn6.0 treatments. The control treatment (Zn0) produced the lowest grain yield (2.99 t ha−1). The concentrations of N, Zn, and Fe were significantly and positively influenced by Zn treatment. The crop varieties did not differ significantly in terms of N and Zn concentrations. However, the grain Fe concentration was remarkably higher in ‘BARI ...

Bijoy was studied through a field experiment at Bangladesh Agricultural University (BAU) farm, Mymensingh during 2009-10 rabi season. The BAU farm belongs to Old Brahmaputra Floodplain agroecological zone (AEZ 9). Texturally the soil was silt loam, with 7.2 pH, 0.81% organic matter and 0.15 mg kg-1 available boron content. The experiment was laid out in a randomized complete block design with five boron rates and four replications. Boron rates were 0, 0.75, 1.5, 2.25 and 3.0 kg ha-1, with boric acid as a source. Every plot received blanket doses of 115 kg N, 25 kg P, 75 kg K and 15 kg S ha-1 from urea, TSP, MoP and gypsum, respectively. Treatment receiving B @ 2.25 kg ha-1 produced the highest grain yield (4.22 t ha-1) which was statistically identical with that obtained with 1.75 kg B ha-1. However, the crop response curve showed 1.90 kg ha-1 to be the optimum boron rate for the maximization of whe...
