| dc.description | Rice (Oryza sativa L) is the unique crop of great antiquity and heart rhythm of
Bangladesh agriculture, as it is the staple food crop covering 74.28% of the total
land area (BBS, 2007). It occupies about 76% of the total cropped area) Rice
accounts for 95% of annual food grain production and provides 75% of the
calories and 55% of the protein in the average daily diet of Bangladesh (Bhuiya
et. al., 2002). Bangladesh is a small country of the third world with huge amount
of population. Most of the people of this country depend on agriculture for their
livelihood. But the amount of arable land is not satisfactory. That being the
reason, food crisis is seen every year. Since horizontal expansion of land is not
possible, vertical crop production has become for future security of food. The
geographical and agro-climatic conditions of Bangladesh are favorable for rice
cultivation. Rice is grown in the Aus, Aman and Boro seasons in Bangladesh. Rice
holds the area of 10.58 million hectares with a production of 26.53 million tons of
grain with the average grain yield of only 2.58 t ha’ (BBS, 2007). | en_US |
| dc.description.abstract | An experiment was conducted at Birganj Upazila of Dinajpur district. The study was carried
out in T. Aman season starting from 25 June 2011 with a view to observing the performance of
different species of trellis-grown vegetable on the ails of growing rice field with regard to both
productivity and profitability. The experiment was laid out in Randomized Complete Block
Design (RCBD) with three replications. Treatments were as factor A: C; = Bottle gourd (B,),
C, = White gourd (W), C; = Yard long bean (Y) and C, = Bitter gourd (Bi), C; = Cucumber,
factor B: I, = Growing vegetables on the ails of rice plots once in T. Aman rice, I, = Growing
vegetables on the ails of rice plots twice, once in T. Aman rice and another is Boro rice, I, =
Growing vegetables on the ails of rice plots thrice in T. Aman rice and Boro rice. The results
revealed that grain yield was the highest in rice + cucumber (C;) and lowest grain yield was
found in rice + bottle gourd (C,). One time vegetable production (I,) produced the highest
grain yield and the lowest grain yield was received from two time’s vegetable production (I,).
In terms of vegetable production, the maximum vegetable yield was obtained from rice + bottle
gourd (C,) and the minimum value was received from rice + yard long bean (C3) crop
combination and as cucumber (C;) was severely damaged by rainfall its yield was not much
remarkable, On the basis of intensity of vegetable I; treatment gave the highest vegetable yield.
Highest rice equivalent yield was found from rice + bottle gourd (C,) crop combination and
lowest value was found from rice + cucumber (Cs) crop combination. The higher rice
equivalent yield was found in I; treatment. On the other hand, the lower rice equivalent yield
was obtained from I, treatment. Among the treatment combination the highest vegetable yield
and rice equivalent yield was recorded from CI; (i.e. rice + bottle gourd with one time
vegetable cultivation) treatment combination. The lowest value of vegetable yield and rice
equivalent yield was recorded respectively from C3l, and CsI, treatment combinations. The
highest value of gross return was obtained from the C,I, treatment combination (i.e. rice + bottle
gourd with one time vegetable cultivation). On the other hand, the lowest value of gross return
was recorded from the treatment C;l>. The highest net return was observed that the C,I, treatment
combination (rice + bottle gourd with one time vegetable cultivation) and the lowest net return was
observed from the C3l, treatment combination (rice + yard long bean with two times vegetable
cultivation). The highest benefit-cost ratio was recorded from CI, treatment combination (rice +
bottle gourd with two times vegetable cultivation) and the lowest benefit-cost ratio was observed
in C3], treatment combination i.e. rice + yard long bean with two times vegetable cultivation. | en_US |
