The experiment was laid-down to determine the inter and intra row spacing effect on the growth, seed and oil production of safflower crop. With regard to the effects of intra-row spacing, the maximum plant height (80.43 cm) was recorded at narrow . The highest biomass yield (53.6 ton ha-1) was recorded at 40 x 60cm and no further increases was observed when intra spacing increase to 50 cm nor inter row spacing increase up to70cm. The experiment result revealed that leaf area index, number of cobs per plant, cob length, number of cobs harvested per hectare and above ground fresh biomass yield and their interactions were highly significantly (P<0.01) affected by inter and intra-row spacing while cob diameter was significantly (P<0.05) affected by inter and intra-row spacing. results showed that highest interaction of 100 grain 3. On the basis of over all results, 22x9.5 cm inter and intra row spacing showed good performance and is therefore, considered best for onion cultivation in the agro-climatic conditions of Dargai, Malakand agency. 2. The intra row spacing in table 2 showed that the tallest plants (260.87 cm) were observed when the maize plant was raised at 20 cm intra row spacing (66,666 plants ha-1), but with no significant difference compared to the plant height (259.66 cm) that obtained at 30 cm plant spacing (44, 444 plants ha-1 ). Management of the Experimental Field Prior to sowing, the land was well prepared by repeated ploughing using oxen plough. Field trials, in which 2 different experiments were considered, have been conducted in NW Italy in order to analyze the yield benefit of high plant density on recent hybrids, considering both intra-row and inter-row plant spacings. (2010). Thus, the width under measurement included: (i) one row of plants matching the middle of the sensor bar in crops grown at 0.70 m or (ii) two rows of . Effect of intra-and inter-row spacing on growth, yield components and grain yield of maize was investigated at Mettu, South Western Ethiopia in 2016, to determine the optimum inter-and intra-row spacing of hybrid maize for maximum yield and yield components. Therefore, it was concluded that to maximize maize kernel number (yield) it is suggested to use the flat method of sowing keeping the inter row spacing 0.60 m.
