The nodulation and growth of cowpea plants (Vigna sinensis Endl. ex Hassk. var. Poona), grown in the CERES phytotron glasshouses, were examined. The plants were grown under six controlled temperature regimes (21, 24, 27, 30, 33, or 36°C day temperature) with ammonium nitrate (NH4N03) additions of 0, 10, 30, and 90 mg nitrogen per pot of six plants; and were grown either under natural daylight or under natural daylight reduced in intensity by one-third by mesh screens. Primary root nodulation was significantly affected by temperature, NH4NO3 level, and light intensity, with an optimum temperature of 24°C. Secondary root nodulation was also affected by light intensity and temperature, but the nodulation pattern (with an optimum temperature of 33°) was almost the inverse of the primary root pattern. Temperature significantly influenced the fresh weight of nodules per plant and the nodule size, with a lesser effect of the NH4NO3 level. Plant dry weight production (tops and roots) was governed by the temperature, NH4NO3 level, and light intensity, the maximum total dry weight being produced at 27°C. Temperature, light intensity, and NH4NO3 level all influenced the plant combined- nitrogen uptake. The nodule leghaemoglobin concentration was significantly reduced at the two extreme temperatures 21° and 36°C. Temperature also markedly affected the nodule structure – particularly the distribution of starch within the nodule.

Elaeisponic is new introducing growing technique to produce vegetables by planting it in the frond based of oil palm trees (Elaeis guineensis Jacq.). However, there was no previous report on vegetable production by using elaeisponic production system, including the use of foliar fertilizers. This study aimed to determine the optimum consentrations and frequency of foliar fertilization for caisim grown in elaesisponic production system. An experiment was conducted in oil palm plantation area by using a factorial randomized complete block design with three replicates. The first factor of treatment consisted of three levels of foliar fertilizer concentration, 1 g l-1, 2 g l-1 and 3 g l-1, and the second factor was application frequency of foliar fertilizer, 7 days after transplanting (DAT), 7, 14 DAT and 7, 14, 21 DAT. Crop responses were determined on leaf greenness (SPAD index), shoot fresh weight (g), root fresh weight (g), leaf area (cm2) and plant dry weight.  Results indicated that both concentration of foliar fertilizer and frequency of application as wells as its interaction did not significatly affect leaf greenness, leaf area, shoot fresh weight, root fresh weight and plant dry weight of caisim plants.  Further research should be addressed on optimizing the use of palm oil frond bases as growing medium for vegetable production.  Keywords: Elaeisponic Production System; Brassica juncea L; Foliar Fertilizer; Frequency of Application.
