Abstract

Pertumbuhan dan perkembangan tanaman, khususnya tanaman kedelai banyak dipengaruhi oleh faktor lingkungan seperti suhu, curah hujan, kelembaban udara (faktor iklim), air, dan unsur hara. Penanaman pada waktu yang tepat dengan mempertimbangkan kondisi iklim yang sesuai dapat meningkatkan pertumbuhan dan hasil tanaman kedelai secara optimum. Penelitian ini bertujuan untuk memprediksi waktu tanam dan pemberian air irigasi terbaik guna memperoleh pertumbuhan, perkembangan, dan hasil kedelai maksimum. Pemberian irigasi cenderung meningkatkan hasil tanaman kedelai pada berbagai waktu tanam. Penanaman kedelai terbaik dilakukan pada bulan Juni, Juli, Agustus, dan September yang merupakan bulan kering di Bogor untuk mendapatkan hasil yang maksimum. Hasil penanaman menunjukkan selisih bobot kering biji yang signifikan antara perlakuan non irigasi dan irigasi. Peningkatan bobot kering biji terlihat pada peningkatan dosis pupuk N hingga 300 kg/ha pada penanaman dengan irigasi. Penanaman kedelai dihindari pada bulan Desember, Januari, Februari, dan Maret yang merupakan bulan basah.

Abstract

Maize and peanuts are important food crops in Indonesia and are generally planted in monoculture and intercropping systems. The water required for monoculture and intercropping is believed to be different. However, comparison analysis of water requirements in monoculture and intercropping is rarely conducted. The research aimed to evaluate the growth and production of sweet corn and peanuts in monoculture and intercropping systems concerning water requirement and crop coefficient. The study was conducted at IPB Experimental Station in Leuwikopo, Bogor, Indonesia from September to December 2022. Sweet corn and peanuts were planted in different cropping systems, i.e., monoculture and intercropping. Water consumption of both cropping systems was evaluated in every growing stage. The experiment used a completely randomized block design and was repeated three times. Results showed that sweet corn growth was not significantly different among cropping systems, but yield from intercropping was lower than monoculture. Intercropped peanuts grew lower than monoculture but did not show any significant difference in yield among cropping systems. Water use efficiency in intercropping was higher than monoculture for both crops, indicating intercropping is a suitable cropping system for limiting soil water availability. The land equivalency ratio was 1.80, concluding that intercropping was more efficient than monoculture in land use by 80%.
