In order to evaluation of the spraying time and cobult nanoparticle fertilizer using chemical and green chemistry methods on morphophysiological indices of cowpea, this research was conducted in a factorial experiment in a the experiment was conducted Randomized Complete Block Design (RCBD) with three replications in Agricultural Research Institute University of Zabol in 2017.The experimental included 4 levels of treatments: (Cobult nanoparticles of plant origin, chemical origin, plant and chemical composition and control), as the first factor and time of spraying in 2 levels (Step 4 leaf and Step 6 leaf as the second factor). The plant density of cowpea was 20 plants/m2 and irrigation was performed twice a week. The results of analysis of variance showed that the time of foliar application and application of nano particles of chemical and plant origin had a significant effect on all studied traits. Based on the results of average comparison, the highest amount of chlorophyll a (13.25 μg/g leaf), chlorophyll b (7.50 μg/g leaf), carotenoids (3.63 μg/g leaf), as well as plant height (34.84 %), number of pods per plant (28.26%), biological yield (45.64%), economic yield (59.10) compared to control treatment, iron (0.26 ppm) and leaf protein ( (46/14 ppm) was obtained from the six-leaf stage and from the combined application of cobalt nanoparticles with chemical and plant origin. In terms of all the measured traits, it seems that the simultaneous application of cobalt nanoparticles chemically and vegetative, through improving the photosynthetic system, increasing leaf duration and photosynthesis, will lead to increased biological and economic yield.

In order to evaluate the effect of soluble time and molybdenum nanoparticles by chemical and green chemistry on morph-physiological indices of mung bean, the present research has been conducted in a factorial experiment, in Randomized Complete Block Design (RCBD) with three replications at Agricultural Research Institute University of Zabol in 2017. The experiment includes 4 levels of treatments: (Molybdenum nanoparticles of plant origin, chemical origin, plant and chemical composition, and control), as the primary factor and spraying time in 2 levels (Step 4 leaf and Step 6 leaf) as the secondary one. The plant density of mung bean has been 33 plants/m2 with the irrigation being performed twice a week. The maximum plant height (47.5 cm), biological yield (5287 kg ha-1), economic yield (634kg ha-1), number of seeds in pod (8), carotenoid, and chlorophyll a and b occur from Step 4-6 and the application of mixed molybdenum nanoparticles. Results from the experiment show that the highest seed protein (40%) has been obtained from plant nanoparticles as well as the 4-leaf stage. Micronutrient can be an effective management solution for production of agricultural products. The results also show that the application of chemical and vegetable molybdenum nanoparticles at 6- leaf stage increase mung bean traits.

Effect of different planting ratios of oat (Avena sativa L.) and vetch (Vicia sativa L.) was assessed on quality and quantity of forage and silage in an intercropping system as completely randomized block design (RCBD) with four replications. The treatments were different planting ratios of oat and vetch including 0:100, 20:80, 40:60, 50:50, 60:40, 80:20 and 100:0 (Oat-Vetch) formed as replacement series. The results indicated that the highest quantitative yield obtained from 40 percent: vetch + 60 percent oat where their fresh and dry matters were 62.88 and 15.72 ton/ha, respectively. The results obtained from analysis of variance showed, all the parameters including crude protein, butyric acid, lactic acid, acetic acid, Natural Detergent Fiber (NDF) and Acid Detergent Fiber (ADF), propionic acid were significantly different with differing planting compositions except ethanol and ammoniac nitrogen. Monoculture of vetch (0-100) produced the highest level of crude protein, butyric acid and lactic acid whereas maximum acetic acid was obtained from 20 percent vetch + 80 percent oat. Maximum NDF and ADF observed from 40 percent vetch + 60 percent oat and the highest level of propionic acid were related to oat monoculture. Generally the ratio of 40 percent vetch + 60 percent oat with maximum of quality and quantity of yield was superior to others and it was acceptable as qualitative characteristics.
