Abstract

The research aims to determine the competition index and the maximum number of sedge populations that can be tolerated by peanut. In this regard, research has been carried out using additive, substitution and dynamic experimental models. The research results showed that the competition index of sedge when peanuts were 60 DAP was 0.0659 so that sedge were able to reduce peanut yields by 6.590%. Meanwhile, at 90 DAP the competition index is 0.0733, so that sedge have the potential to reduce peanut yields by 7.330%. The peanut yield loss calculated based on the weighted dominance variable is in accordance with the predictions of the sedge competition index, namely the yield loss of peanuts aged 60 DAP and 90 DAP is 66.00% and 72.60%. Meanwhile, based on the prediction of the sedge competition index, peanut yield losses were 65.90% and 73.30%. The growth of peanuts aged 60 DAP and 90 DAP began to be suppressed by the presence of 5.43 and 5.24 clumps per m2 of sedge, while for peanuts to suppress sedge growth, a population of 7.58 and 5.30 clumps per m2 was required. The presence of sedge that can be tolerated by peanuts aged 60 HST ≤ 5.43 clumps per m2 and aged 90 DAP ≤ 5.24 clumps per m2. The relative space occupation (RSO) of sedge when peanuts are 60 DAP is higher than the RSO of peanuts, whereas when peanuts are 90 DAP, the RSO of sedge is lower compared to the RSO of peanuts, namely the population density of peanuts and sedges 5-35 clumps per m2, the RSO value of peanuts is 57.00 – 94.00%, while the RSO value of nut weeds is 47.40 – 92.00%, with a comparative value of 9.60 – 2.00%

Abstract

Cayenne pepper (Capsicum frutescens L.) is an agricultural commodity with a high economic value. Increasing cayenne pepper production in dry lands is hampered by limited water availability. Therefore, water use efficiency is required, one of which is the implementation of drip irrigation. This study aimed to test the performance of a drip irrigation system in the cayenne pepper farmland of Slengen Village, which is located in the lowlands with a dry climate (D4). Emitter discharge, emitter flow rate, and crop water requirements were used to determine the length of time the drip irrigation system was operational at each growth phase. The results show that the emitter discharge uniformity coefficient was 86.6% with a droplet distribution efficiency of 89.80%, which is included in the good category. This indicates that the drip irrigation system is suitable for irrigating plants evenly within the required water volume.
