Abstract

A field experiment was conducted at the research farm of Assam Agricultural University, Jorhat, Assam during winter (rabi) seasons of 2019–20 and 2020–21 to study the effect of integrated nutrient management on growth and quality of lettuce (Lactuca sativa L.). The experiment was laid out in a randomized block design (RBD) with eight treatments and three replications. The treatment combinations were T1, Control; T2, 40:20:40 NPK kg/ha; T3, 40:20:40 NPK kg/ha + FYM 2 tonnes/ha; T4, 40:20:40 NPK kg/ha + FYM 2 tonnes/ha + PSB; T5, FYM 3 tonnes/ha + PSB; T6, 40:20:40 NPK kg/ha +VC 1 tonnes/ha; T7, 40:20:40 NPK kg/ha + VC 1 tonnes/ha + PSB and; T8, VC 2 tonnes/ha + PSB. Observations on the growth parameters were taken at 30 DAP, 45 DAP and at harvest. Among the treatments, T7 recorded the highest yield (27.5 tonnes/ha), net income (192703.00) and other quality parameters. However, the benefit-cost ratio was found maximum (2.6) in the treatment T4 due to lesser cost of FYM as compared to vermicompost used in the treatment T7. Therefore, the combined use of NPK, FYM and PSB (T4) may be recommended for economic as well as environment friendly production of lettuce.

综合营养管理对生菜生长及品质性状的影响

在2019-20和2020-21冬季(rabi)季，在阿萨姆邦乔哈特(Jorhat)阿萨姆农业大学研究农场进行了田间试验，研究了综合营养管理对莴苣(Lactuca sativa L.)生长和品质的影响。试验采用随机区组设计(RBD)， 8个处理，3个重复。治疗组合为T1、对照;T2, 40:20:40 NPK kg/ha;T3, 40:20:40氮磷钾公斤/公顷+ FYM 2吨/公顷;T4, 40:20:40氮磷钾公斤/公顷+ FYM 2吨/公顷+ PSB;T5, FYM 3吨/公顷+ PSB;T6、40:20:40氮磷钾公斤/公顷+VC 1吨/公顷;t7,40:20:40氮磷钾公斤/公顷+ VC 1吨/公顷+ PSB和;T8, VC 2吨/公顷+ PSB。在30 DAP、45 DAP和收获时观察生长参数。其中，T7的产量最高(27.5吨/公顷)，净收入最高(192703.00吨/公顷)，其他品质参数最高。然而，由于与T7处理中使用的蚯蚓堆肥相比，FYM的成本较低，因此T4处理的效益成本比最大(2.6)。因此，氮磷钾、FYM和PSB (T4)配施可促进生菜经济环保生产。
