<p>Intercropping is one way of increasing land productivity. The research was aimed to determine the suitability of soybean promising lines for maize + soybean intercropping based on land productivity assessed by land equivalent ratio (LER). The research was conducted at Kendalpayak Station Research, Malang, in February to May 2016, using factorial randomized block design, repeated three times. The first factor was cropping system (monoculture and intercropping), the second factor was 55 soybean genotypes. Spacing for maize in the intercropping system was 2.2 m x 0.5 m x 0.2 m, and for soybean was 0.35 m x 0.10 m. In monoculture, spacing for maize was 0.75 m x 0.25 m and for soybean was 0.35 m x 0.10 m. The results showed there was five genotypes suitable for intercropping of maize + soybean based LER value, ie G//IT7-3, M0706//MI196-3, M0706//MI197-4, M0706//MI199-1, and M0706//MI199-2, with LER value of more than 1. Intercropping of maize with these soybean lines, gives a higher land productivity than monoculture.<br /><br />Keywords: Glycine max (L.)

The objective of the research was to know of agronomic performance and farming feasibility of soybeans which are cultivated by polyculture and monoculture systems. Soybeans were planted in two systems namely monoculture (soybean) and polyculture (soybean are intercropped with 3 years of rubber trees).  Both of Dena 1 and Anjasmoro varieties were cropped in those systems. Soybeans are cropped by using planting machine (ATBJ) which has planting distance 20 cm x 40 cm (1-2 seeds per hole). Plants were fertilized with 50 kg Urea per ha, 150 kg TSP per ha, 150 kg KCl per ha, manure 2,000 kg per ha, and dolomite 1,000 kg per ha. Mower were used for harvesting. The results showed that the growth and soybean yield in monoculture system was better than the polyculture. Yield of Anjasmoro in monoculture was 15.35 ku per ha, whereas the polyculture was 4.72 ku per ha. Meanwhile, the productivity of Dena 1 was 14.80 ku per ha and 7.38 ku per ha in polyculture system. The polyculture had a higher value of the land equivalent ratio than monoculture of rubber trees. Economically, the two planting systems that were examined also deserve to be done by farmers, where the value R/C > 1

Abstract Three treatments were tested with four replications at RCBD, namely cassava monoculture, corn twice under cassava intercropping, and corn with corn monoculture where the second corn was planted 5 days after harvested. Planting distance of cassava in monoculture was 100x100 cm, and in intercropping was 200x50 cm, by which corn was planted in 50x30 cm, 1 seed per hole. All plots received dairy cattle manure 5 t ha-1. Fertilizer applied for cassava was Urea 100 kg ha−1, Ponska 200 kg ha−1 and KCl 100 kg ha−1 split into two applications two weeks after cassava planting, then when first of corn was harvested. Corn fertilization was Ponska 150 kg ha−1 + Urea 100 kg ha−1 every 3 months and split into two applications: 1 week and 4 weeks after corn was planted. Cassava and twice corn fertilization was Urea 300 kg ha−1 + Phonska 400 kg ha−1 + KCl 100 kg ha−1. Results showed that cassava monoculture can be improved by inserting of twice corn in between rows. Under sole cropping cassava, the B/C ratio was the highest 1.61, however with incorporating twice of corn the B/C ratio was 1.58. Intercropping cassava and twice of corn resulted in the Land Equivalent Ratio 2.146. By intercropping cassava with corn twice at the end of dry season, there was an opportunity to find corn biomass for dairy cattle. Under intercropping, cassava was able to produce 21.5 t ha−1 of fresh roots, while first and second of corn produced fresh biomass of 34 t ha−1 and 28 t ha−1 respectively.

Maize (Zea mays L.) being a widely space crop were tried with different combinations of legumes cowpea (Vigna unguiculata L. Walp), frenchbean (Phaseolus vulgaris L.) and blackgram (Vigna mungo L.) as intercrops at different planting geometry to find out their suitability during 2009, 2010 and 2011 at eastern Himalayan, Arunachal Pradesh, India. Three experiments were carried out in sequence to identify suitable planting geometry to accommodate intercrops, screening best legume crops and subsequently best performed row ratio of maize and legume crops were intercropped in third experiment with 1:1, 1:2 and 1:5 row proportions. Sole maize gave the maximum grain yield with 4571.1 kg ha-1, whereas, stover yield was highest with maize-cowpea intercrop at 1:2 row ratios (8013.4 kg ha-1) and 57.1 kg ha-1 day-1 production efficiency followed by frenchbean and least with blackgram. Competition indices like land equivalent ratio (LER) was highest with 1:2 row ratio of maize-frenchbean (1.66), land equivalent coefficient (0.67). But, highest area time equivalent ratio (ATER) noticed with 1:2 row ratio of maizeblackgram (1.47). Relative crowding coefficient (K) and competition ratio were noticed higher with 1:2 row ratio of maize-cowpea, whereas, cowpea combinations has better crowding coefficient and blackgram combinations registered better competitiveness. Monetary advantage index (MAI) was 6433.2 with 1:2 row ratio of maize-blackgram followed by maize-cowpea and lowest with maize-frenchbean with the trend of 1:2>1:5>1:1 row ratios.
