Abstract

An experiment was conducted at Central Research Farm, BARI, Gazipur and On Farm Research Division, BARI, Noakhali during Rabi season of 2017-18, 2018-19 and 2019-20 to develop a fertilizer recommendation for chilli with garlic intercropping system. Six treatment combinations viz. T1= 100% RDCF of chilli + 0% RDCF of garlic, T2= 100% RDCF of chilli +10% RDCF of garlic, T3= 100% RDCF of chilli + 20% RDCF of garlic, T4= 100% RDCF of chilli +30% RDCF of garlic, T5= 100% RDCF of chilli +40% RDCF of garlic and T6= 100% RDCF of chilli +50% RDCF of garlic were tested. The experiment was laid out in randomized complete block design with 3 replications. Both chilli and garlic characters significantly influenced by different treatment combinations. The maximum yield of chilli (10.12 and 9.10 t ha-1 at Gazipur and Noakhali, respectively) and garlic (3.70 and 3.55 t ha-1 at Gazipur and Noakhali, respectively) were obtained from T6 treatments which were statistically similar with T5 treatment. Chilli equivalent yield progressively increased with the increase of inorganic fertilizers. The results showed that T6 provided the highest CEY (17.52 and 16.18 t ha-1 at Gazipur and Noakhali, respectively) followed by T5 (17.47 and 16.14 t ha-1 at Gazipur and Noakhali, respectively). The highest gross margin (Tk. 339755 ha-1 and Tk 310198. ha-1at Gazipur and Noakhali, respectively) as well as BCR (4.50 and 4.32 at Gazipur and Noakhali, respectively) were obtained from T5 treatment while the lowest net return (Tk. 266661 ha- 1 and Tk. 242264 ha-1at Gazipur and Noakhali, respectively) as well as BCR (3.92 and 3.76 at Gazipur and Noakhali, respectively) were observed from T1 treatment. Though T6 treatment gave higher yield over all the treatments but it showed lower BCR compared to T5 treatment due to higher cost involvement for inorganic fertilizer. Bangladesh Agron.

辣椒-大蒜间作系统肥料推荐

2017-18年、2018-19年和2019-20年拉比季节，在Gazipur BARI中央研究农场和Noakhali BARI农场研究部进行了一项实验，以制定辣椒与大蒜间作系统的肥料建议。对6个处理组合进行了试验，即T1=100%RDCF辣椒+0%RDCF大蒜，T2=100%RDCF+10%RDCF大蒜，T3=100%RDCF+20%RDCF蒜，T4=100%RDCF+30%RDCF蒜头，T5=100%RDCF辣椒+40%RDCF蒜和T6=100%RDCFR+50%RDCF。实验采用随机完全区组设计，共3次重复。不同处理组合对辣椒和大蒜性状均有显著影响。T6处理获得了辣椒（Gazipur和Noakhali分别为10.12和9.10 t ha-1）和大蒜（Gazipu和Noakhari分别为3.70和3.55 t ha-1）的最大产量，这在统计学上与T5处理相似。辣椒当量产量随着无机肥料的增加而逐渐增加。结果表明，T6提供了最高的CEY（Gazipur和Noakhali分别为17.52和16.18 t ha-1），其次是T5（Gazipu和Noakhari分别为17.47和16.14 t ha-）。毛利率最高（339755坦桑尼亚先令和310198坦桑尼亚先令）。Gazipur和Noakhali分别为ha-1）和BCR（Gazipur和Noakhari分别为4.50和4.32），而Gazipur和Noakhal分别为266661公顷-1和242264公顷-1，净收益最低。尽管T6处理的产量高于所有处理，但与T5处理相比，由于无机肥料的成本较高，其BCR较低。孟加拉国Agron。J.2022，25（1）：7-14
