“…Intercopping with S. splendida caused the growth of C. pubescens and C. ternatea to be lower than the sole crop. Growth of C. pubescens and C. ternatea was hindered by the presence of competition in uptaking nutrient elements in soil (Oseni, 2010). S. splendida grew quickly and forming stolons so that more nutrient were absorbed than C. pubescens and C. ternatea.…”

This research was conducted to evaluate production, different competition indices and nutritive value of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in monoculture and mix cropping system on peat soil land. The experiment was set up in a randomized complete block design with five treatments and three replications. The five treatments were: S. splendida sole cropping (SS), C. pubescens sole cropping (CP), C. ternatea sole cropping (CT), S. splendida and C. pubescens mix cropping (SS/CP) and S. splendida/C. ternatea mix cropping (SS/CT). The DM yield of S. splendida in mixed cropping with C. pubescens increased 43.4% and in mix cropping with C. ternatea increased 15.7% compared to sole S. splendida. The value of land equivalent ratio of SS/CP (LER SS/CP ) was >1. The LER SS/CT value was <1. The crowding coefficient value of S. splendida (K SS ) was higher than K CP and K CT . The total value of K SS/CP and K SS/CT were >1. The competition ratio (CR) values of S. splendida in both mix cropping were >1. The agressivity (A) values of S. splendida in both mix cropping were positive. The crude protein, NDF and ADF content of forage were not affected by mix cropping system. In conclusion, mix cropping in peatland do not affect productivity and nutritive value of S. splendida, C. pubescens, and C. ternatea. S. splendida is more effective in exploiting environmental resources when intercropped with C. pubescens compared to C. ternatea on peatland.Key words: croppin�� system, �ora��e, production, �uality croppin�� system, �ora��e, production, �uality Nilai agressivity (A) S. splendida pada kedua pertanaman campuran adalah positif.

Dapat disimpulkan bahwa pertanaman campuran di lahan gambut tidak mempengaruhi produktivitas dan nilai nutrisi S. splendida, C. pubescens, dan C. ternatea. S. splendida lebih kompetitif dan dominan dibanding C. pubescens dan C. ternatea di lahan gambut. ABSTRAK

“…In the intercropping system, a tall statured crop is intercropped with a short statured crop, such as the cereal and legume intercropping [3–4]. The low yield of short statured intercrop, which is mainly contributed by the decrease of intercepted PAR, is often regarded as the limiting factor for the application of intercropping [4–5].…”

PAR Interception and Utilization in Different Maize and Soybean Intercropping Patterns

The crop intercepted photosynthetically active radiation (PAR) and radiation use efficiency (RUE) vary markedly in different intercropping systems. The HHLA (horizontally homogeneous leaf area) and ERCRT (extended row crop radiation transmission) models have been established to calculate the intercepted PAR for intercrops. However, there is still a lack of study on the intercepted PAR and RUE under different intercropping configurations using different models. To evaluate the intercepted PAR and RUE in maize and soybean under different intercropping systems, we tested different strip intercropping configurations (SI1, SI2, and SI3 based on ERCRT model) and a row intercropping configurations (RI based on HHLA model) in comparison to monoculture. Our results showed that the intercepted PAR and RUE of intercropping systems were all higher than those of monoculture. The soybean intercepted PAR in strip intercropping was 1.35 times greater than that in row intercropping. In row intercropping (RI), the lack of soybean intercepted PAR resulted in a significant reduction of soybean dry matter. Therefore, it is not the recommended configuration for soybean. In strip intercropping patterns, with the distance between maize strip increased by 0.2 m, the intercepted PAR of soybean increased by 20%. The SI2 (maize row spacing at 0.4 m and the distance between maize strip at 1.6 m) was the recommended configuration to achieve the highest value of intercepted PAR and RUE among tested strip intercropping configurations. The method of dry matter estimation using intercepted PAR and RUE is useful in simulated experiments. The simulated value was verified in comparison with experimental data, which confirmed the credibility of the simulation model. Moreover, it also provides help in the development of functional-structural plant model (FSPM).

“…However, studies on mung beanturmeric intercropping are not much available. The competition functions viz land equivalent ratio (LER), relative crowding coefficient (K), competitive ratio (CR), aggressiveness, monetary advantage index (MAI) and system productivity index (SPI) have been developed to describe the competition and possible economic advantages of intercropping systems (Banik et al, 2000 ;Ghosh, 2004;Yilmaz et al, 2008;Midya et al, 2005;Oseni et al, 2010).…”

An intercropping experiment was conducted with varying combinations of turmeric and mung bean to find out the efficacy of productivity and economic return through competition functions. Treatments were evaluated on the basis of several competition functions, such as land equivalent ratio (LER), aggressiveness, competitive ratio (CR), monetary advantage index (MAI) and system productivity index (SPI). Results showed that rhizome yields of turmeric were higher in intercropping system than in mono crop. It indicated that intercropping of mung bean did not affect the rhizome yield of turmeric. However, turmeric (100 %) + 3 row mung bean (100 %) in between turmeric lines intercropping system exhibited maximum yield of both the crops as well as turmeric equivalent yield, LER, competitive indices values, SPI and MAI (Tk. 2,44,734.46 ha -1 ) compared to the other intercropping combinations and the mono crops. Aggressiveness of intercrop indicated dominance of turmeric over mung bean in all the combinations except turmeric (100 %) + 1 row mung bean (33 %). Competition functions of intercroping suggested beneficial association of turmeric and mung bean crops. The study revealed that mung bean could be introduced as intercrop with turmeric without hampering rhizome yield with higher benefit additionally increasing mung bean production area. Obravnavanja so bila ovrednotena na osnovi različnih kompeticijskih funkcij kot so ekvivalent zemljišča (LER), agresivnost, kompeticijsko razmerje (CR), denarni indeks (MAI) in sistemski produktivnostni indeks (SPI). Rezultati so pokazali, da je bil pridelek korenik kurkume večji v vseh sistemih z medposevki kot v čisti sadnji. Pokazali so tudi, da kombinirano gojenje z zlato vinjo ni povzročilo zmanjšanja pridelka korenik kurkume. Površine z vrstami čiste kurkume (100 %), kombiniranimi s trovrstnimi pasovi zlate vinje (100 %) so imele večji pridelek obeh poljščin kot tudi največje vrednosti za ekvivalent pridelka, LER, kompeticijski indeks, SPI in MAI (Tk. 2,44,734.46 ha -1 ) za kurkumo v primerjavi z drugimi sistemi mešanega gojenja in čistimi kulturami. Analiza agresivnosti pri različnih kombinacijah mešanega gojenja je pokazala prevlado kurkume nad zlato vinjo v vseh kombinacijah, razen v sistemu, kjer je bil nasad kurkume (100 %), kombiniran s po eno vrsto zlate vinje (33 %). Kompeticijske funkcije mešanih načinov gojenja so pokazale, da je glede na pozitiven učinek smiselno kombinirati omenjeni poljščini. Raziskava je pokazala, da bi se zlata vinja lahko uvedla kot medkultura kurkume, ne da bi zmanjašala pridelek njenih korenik, hkrati pa bi to predstavljalo dodatno možnost povečanja površin za pridelavo zlate vinje.
