Sodium nitroprusside (SNP), a nitric oxide (NO) donor, was added into controlled release fertilizer (CRF) or sprayed on leaves to supply NO on iron deficiency stress in peanut (Arachis hypogaea Linn) plants growing on calcareous soils. Iron deficiency reduced plant growth and chlorophyll content. NO improved plant growth and alleviated leaf interveinal chlorosis, and increased the activity of root Fe<sup>III</sup> reductase and the concentration of available iron in cultured soil, suggesting that NO action could be related to iron availability to the plant. The actual photochemical efficiency (&Phi;PSII) and photochemical maximum efficiency of PSII (Fv/Fm) were increased, and minimum fluorescence yield (Fo) was decreased under NO-treated condition, which supported the protective effect of NO on photosystem II (PSII) in peanut leaves. NO increased the activities of antioxidant enzymes, and reduced malondialdehyde (MDA) accumulation. These results suggest that exogenous NO could alleviate iron deficiency induced chlorosis of peanut plants growing on calcareous soil. &nbsp;

Iron deficiency chlorosis (FeDC) can cause significant seed yield reduction in dry beans (Phaseolus vulgaris L.) grown on high-pH calcareous soils. To determine the effects of FeDC on seed yield, and the effect of Fe-spray as a correction factor for FeDC, 22 breeding lines/cultivars were planted on high-pH (8.0), calcareous (3.2–3.5 calcium carbonate equivalent), and low-Fe (1.8–4.2 ppm DTPA) sandy clay loam Tripp soils at Mitchell and Scottsbluff in western Nebraska. A split-plot design was used with Fe treatments as main plots and breeding lines/cultivars as subplots. Three foliar sprays of Fe-EDDHA (2.4 kg·ha–1) were applied at V4, R5, and R7 dry bean growth stages, during 1996 and 1997. Leaf chlorosis was measured simultaneously by using a Minolta Chroma-meter (CIE L* a* b* color space system), a Minolta Chlorophyll-meter (chlorophyll content index), and by visual ratings (1 = normal green to 5 = severe chlorosis). In 1996 no significant Fe-spray × line interaction (P = 0.776) and Fe-spray effect (P = 0.884) on seed yield was observed. Breeding lines showed significant differences in seed yield (P = 0.0001) with WM2-96-5 being the highest-yielding line (4047 kg·ha–1). In 1997 a significant Fe spray × line interaction (P = 0.029) was observed. The cultivar Chase without Fe spray (3375 kg·ha–1), and lines WM2-96-5 (3281 kg·ha–1), WM2-96-8 (3171 kg·ha–1) with Fe spray were the highest yielding entries under those treatments. Differences in visual ratings after the third Fe spray in 1997 were significant (P = 0.004) for Fe spray × line interaction. In 1996 visual ratings were different only for breeding lines. Chlorophyll content index showed a significant Fe spray × line interaction after the second Fe spray (P = 0.022) and after the third Fe spray (P = 0.0003) in 1997.

Sari. Trichoderma spp merupakan golongan fungi yang bersifat antipatogen, khususnya layu kecambah, sedangkan bokashi merupakan kompos yang diperkaya dengan beberapa mikroba yang bermanfaat bagi pertumbuhan tanaman.Tulisan ini merupakan rangkuman penelitian pot menggunakan kompos Trichoderma spp sebagai pelapis benih terdeteriorasi disertai bokashi kotoran hewan yang dilakukan pada tanah lahan kering dan tanah sawah pada tahun 2014 dan 2017. Percobaan pertama membandingkan efektivitas beberapa agen hayati sebagai pelapis benih pengaruhnya terhadap vigor benih dan hasil tanaman. Hasil percobaan menunjukkan penggunaan kompos Trichoderma hasilnya lebih baik dibandingkan agen hayati lainnya. Hasil percobaan selanjutnya menunjukkan  bahwa pelapisan benih dengan 1 sampai 3 g  kompos Trichoderma spp per 100 butir benih pengaruhnya tidak nyata dibandingkan dengan penggunaan pelapis benih berupa pestisida, baik terhadap vigor  maupun hasil biji per tanaman. Pemberian bokashi sebaliknya secara nyata mampu meningkatkan hasil biji per tanaman . Pemberian bokashi 15 t ha-1menghasilkan biji seberat 19.83 g per tanaman  atau setara dengan 2,379 t ha-1 atau 27,3 % lebih tinggi dari kontrol.Kata kunci : Benih terdeteriorasi, pelapisan benih, Trichoderma, Bokashi Abstract. Trichoderma spp is a group of antipatogenic fungi, especially seedling wilted, while bokashi is a compost enriched with some microbes that are beneficial to plant growth. This paper is a compilation of pot experiment using Trichoderma compost for coating deteriorated seed and accompanied by bokashi on dry land soil and paddy soil in 2014 and 2017 respectively. The first experiment compares the effectiveness of several biological agents as a seed coating of its effect on seed vigor and yield. The results of first experiment showed that the use of 2 g Trichoderma compost 100 seeds-1 was better than other biological agents. However between 1.2 and 3 g of Trichoderma compost per 100 seeds was not significant effect on seed vigor and yield. The results of experiment showed that the coating of seeds with 1 – 3 g of Trichoderma spp compost 100 compared with pesticide seed coatings. Increased of yield only affected bokashi application. Application of bokashi 15 t ha-1 abble to produce 19.83 g seed per plant or equivalent to 2.379 t ha-1 or 27.3% higher than the control.Key words: deteriorated seeds, seed coating, Trichoderma, bokashi
