The area coverage and productivity of linseed decreased from time to time; even there is no crop package and recommended row spacing and seed rate at regional level due to lack of attention by researchers and also by farmers. In Ethiopia, linseed has been cultivated for two primary purposes, seed and oil use. Its production in Ethiopia country is characterized by low input, low yield and poor product quality mainly due to attitude and poor management practices such as lack of proper weed management system, poor seed and field hygiene, poor seed bed preparation, inadequate plant nutrition, inappropriate seeding rate and spacing (mostly broad casting), improper threshing ground and improper cleaning. Field experiment was carried out to evaluate the effects of seed rate and row spacing on the yield and yield components of linseed, during 2017/2018 cropping season at Dabat district, North Western Ethiopia. KULUMSA1 (CHILALO) was used as test crop. Factorial combinations of three row spacing, (20, 25, and 30 cm) and three seed rates, (40, 45 and 50kgs) were laid out in RCBD with three replications.  Data regarding different parameters were recorded from days to sowing up to different stages. Statistical analysis of data showed that most of the parameters were affected by the main effects of Seed Rates and Row spacing. The main effect of seed rate was highly significant for days maturity, thousand seed weight and harvest index of linseed. More over it was significant for days to flower and number of capsule per plant, but it was not significant to plant height and bio mass yield. The main effect of row spacing was significant for days to maturity. The interaction of seed rate and row spacing was highly significance (p<0.05) for number of primarily branch per plant and seed yield. It was not significant on number of seeds per capsule, number of capsule per plant and thousand seed weight. The main finding of this research is highest seed yield (1771 kg ha-1 ) was obtained at 40kg ha-1 x 25 cm of row spacing while the lowest seed yield (752kg ha-1) was recorded at 50 kg ha-1 x 30 cm. 40kg ha-1 and 25cm is recommended to increase yield of linseed and its components. In conclusion the effect of seed rate and row spacing affects the important yield components of linseed.

Improved agronomic practices increases yield potential of chickpea in different agroecology of the country. In this view a field experiment was conducted to assess the influence of inter-and intra row spacing on yield and yield components of chickpea (Cicer arietinum L.) in Jimma Horro district of Kellem Wollega Zone, Western Oromia, Ethiopia. The treatment consisted of three inter-row spacing (20, 30 and 40 cm) and four intra-row spacing (5, 10, 15 and 20 cm). The experiment was laid out in a randomized complete block design in factorial arrangement with three replications. The highest (52) number of pods plant-1 was obtained with the interaction effect of 40 cm inter and 20 cm intra row spacing. The highest dry biomass (8457 kg ha-1) was recorded at 20 cm × 5 cm spacing while the lowest dry biomass (5413 kg ha-1) was recorded at 40 cm × 20 cm spacing combination. Significantly  higher  (248 g) 1000 grain weight was recorded under 40 cm with 20 cm spacing and lowest (165 g) 1000 grain weight under 30 cm x 5 cm row spacing. The highest (1625 kg ha-1) seed yield of chickpea was obtained from 30 cm x 15 cm and the lowest seed yield (1096 kg ha-1) was recorded from 20 cm x 5 cm row spacing. The highest harvest index (34.03%) was achieved for the interaction of 40 cm inter- and 20cm intra-row spacing and the lowest harvest index (12.14%) under 20 cm x 5 cm row spacing. Thus 30 cm inter-row with 15 cm intra-row spacing can tentatively be recommended for the production of chickpea in the study area as compared to the current recommendation of 30 x 10 cm. Further research would be needed at more locations and seasons to give conclusive recommendations.

Planting date (PD), seeding rate (SR), relative maturity (RM) of cultivars, and row spacing (RS) are primary management factors affecting soybean (Glycine max (L.) Merr.) yield. The individual and synergistic effects of PD, SR, RM, and RS on seed yield and agronomic characteristics in North Dakota were herein investigated. Early and late PD, early and late RM cultivars, two SR (408,000 and 457,000 seed ha−1), and two RS (30.5 and 61 cm) were evaluated in four total environments in 2019 and 2020. Maximizing green canopy cover prior to the beginning of flowering improved seed yield. Individual factors of early PD and narrow RS resulted in yield increase of 311 and 266 kg ha−1, respectively. The combined factors of early PD, late RM, high SR, and narrow RS improved yield by 26% and provided a $350 ha−1 partial profit over conventional practices. Canopy cover and yield had relatively weak relationships with r2 of 0.36, 0.23, 0.14, and 0.21 at the two trifoliolate, four trifoliolate, beginning of flowering, and beginning of pod formation soybean growth stages, respectively. Producers in the most northern soybean region of the USA should combine early planting, optimum RM cultivars, 457,000 seed ha−1 SR, and 31 cm RS to improve yield and profit compared to current management practices.
