farmers were 5346 kg <strong>and</strong> 4436 kg/ha in Boro <strong>and</strong> T.aman rice, respectively. In c<strong>on</strong>trast, the smallfarmers achieved the lowest yield (5071 kg <strong>and</strong> 4229 kg/ha in Boro <strong>and</strong> T.aman rice, respectively). Butthe average grain yields of Boro <strong>and</strong> T.aman rice were 5306kg <strong>and</strong> 4367 kg/ha, respectively at all thesites. The main reas<strong>on</strong>s underlying it were that large <strong>and</strong> medium farmers applied the producti<strong>on</strong> inputsnear to the recommended rates but the small farmers had low access to these inputs due to high price.Table 4.1.32 Grain yield of rice in study areasFarmers’categoryGrain yield of rice (kg/ha)Rajshahi Rangpur Jessore Average (all sites)Boro T.aman T.aus Boro T.aman Boro T.aman Boro T.amanLarge 5823 4878 3928 5424 4328 5256 4105 5501 4437Medium 5546 4824 3987 5362 4287 5131 4198 5346 4436Small 5042 4477 3736 5299 4136 4873 4073 5071 4229Average 5470 4726 3884 5362 4250 5087 4125 5306 4367CV (%) 10.34 9.12 10.32 9.87 8.73 9.17 8.65 - -4.1.33 Frequency distributi<strong>on</strong> of Boro rice yieldThe frequency distributi<strong>on</strong> <strong>for</strong> the yields of Boro rice in Rangpur is presented in Fig. 4.1.5 <strong>and</strong> it showsthat the farmers at this locati<strong>on</strong> obtained the grain yield ranging from 3000kg to 7500 kg/ha.

4.1.34 Producti<strong>on</strong> cost <strong>and</strong> profitability of rice grainBoro riceThe producti<strong>on</strong> package <strong>and</strong> profitability analysis <strong>for</strong> Boro rice in Rajshahi, Rangpur <strong>and</strong> Jessore sitesare presented in Table 4.1.33 <strong>and</strong> Annexes 11-12. It is observed that the average variable <strong>and</strong> total costswere Tk. 50,692 <strong>and</strong> Tk. 60,692/ha. Besides, the average gross return was Tk. 69,663/ha. The averagebenefit cost ratio (total cost basis) was 1.15. From the results, it can be reviewed that Boro ricecultivati<strong>on</strong> <strong>for</strong> grain purpose is not that much profitable.Table 4.1.33 Producti<strong>on</strong> cost <strong>and</strong> profitability of Boro rice <strong>for</strong> grain at all sites (2008-09)ItemQtyRajshahi Rangpur Jessore Average (all sites)ValueValueValueValueQtyQtyQty(Tk./ha)(Tk./ha)(Tk./ha)(Tk./ha)Ploughing number 3.16 2344 4.4 3236 3 3900 4 3160<strong>Seed</strong> (kg) 43 989 39 1160 30 900 37 1016Manure (kg) 2228 1114 6203 3102 7500 3750 5310 2655Oil cake (kg) - - - - 120 2400 120 2400Urea (kg) 338 4060 225 2696 250 3000 271 3252TSP/DAP (kg) 70 2800 61 2440 60 2400 64 2547MP (kg) 60 1810 46 1380 88 3520 65 2237Gypsum (kg) 57 285 39 195 75 350 57 277Zinc Sulphate (kg) 3 180 1.9 224 7.75 465 4 290Irrigati<strong>on</strong> (No.) - 13117 - 10000 C<strong>on</strong>. 7100 - 10072Weeding (No.) 3 - 1.8 - 3 - 2.6 -Herbicide - 594 - 1027 - - 811Insecticide - 1098 - - 2300 - 1098Human Labour (MD) 227 27200 164 19640 213 21300 201 22713a) Total variable cost - 55591 - 45100 51385 - 50692b) Fixed cost (<strong>for</strong> l<strong>and</strong>) - 10000 - 10000 - 10000 - 10000Total cost (a+b) - 65591 - 55100 61385 - 60692Yield (kg): Grain 5656 62220 5362 58978 6000 75000 5673 65399Straw 11350 2838 7507 3754 6200 6200 8352 4264Gross return (Tk./ha) - 65057 - 62732 81200 - 69663Gross margin:a) Variable cost basis - 9466 - 17633 29815 - 18971b) Total cost basis - -534 - 7633 19815 - 8971BCR (total cost basis) - 0.99 - 1.14 1.32 - 1.15Costing rate (Jessore): Rice seed @ Tk. 30.00/kg, Compost @ Tk. 0.50/kg, Oil cake @ Tk. 20.00/kg, Urea @ Tk.12/kg, TSP @ Tk. 40.00/kg, MP @ Tk. 40.00/kg, Gypsum @ Tk. 5.00/kg, Zinc sulphate @ Tk. 60.00/kg, Labourwage @ Tk. 100.00/m<strong>and</strong>ay, Rice grain @ Tk. 12.50/kg, Rice straw @ Tk. 1.00/kgT.aman riceTable 4.1.34 shows the cost <strong>and</strong> return of T.aman rice. The total cost of producti<strong>on</strong> of T.aman rice ha -1was Tk 32,820 <strong>and</strong> the gross return was Tk 59,500. The gross margin was Tk 26,680 with BCR of 1.81.The cost of crop producti<strong>on</strong> <strong>and</strong> its return mainly depend <strong>on</strong> the rate of inputs used (seed, fertilizers,pesticides etc.), l<strong>and</strong>/soil type, number of irrigati<strong>on</strong> needed, number of labor <strong>and</strong> their wage rate,management practices, marketing facilities of the crop products etc. As all these factors differ from <strong>on</strong>elocati<strong>on</strong> to another across the study sites, the producti<strong>on</strong> cost <strong>and</strong> hence, the ec<strong>on</strong>omic return <strong>for</strong> ricegrain/seed as assessed through the present study presumably varied widely.41
