“…Whole period: During the whole period, change in mean yield was mainly contributing for the production of groundnut in all districts and divisions in Karnataka except Tumakur, Chitradurga, Bellary districts and Bangalore division followed by the change in mean area. The results are similar with Devi et al (2017) who reported that the yield effect had very high (93.96 %) influence on pulses production in India. The results are in line with Reddy (2013); Rao and Raju (2005).…”

The study conducted in Karnataka state with an objective to find out the sources of growth and instability of groundnut production. The CAGR, CDI and Hazel's decomposition model was used. The growth pattern showed a downward trend along with higher instability in area, production and yield of groundnut in all the districts during period II. The variation in groundnut production was predominantly due to interaction effect of yield and area during period I, whereas change in mean area largely contributed during period II in the state. The change in mean yield, change in mean area, interaction effect and change in residuals had a stabilizing effect on groundnut production. The change in mean yield and change in mean area was primary sources of growth in all the districts and divisions. The study suggests that the research efforts may be concentrated on developing a suitable yield increasing technology in the state like HYV, expansion of irrigation area under groundnut. It helps to enhance the per unit production of groundnut as well as stabilize the area and yield of the groundnut in the state in particular and country as a whole. Highlights m The interaction effect of mean area and yield are major sources of growth in the state. The marginally highest variability was noticed in production than compared to area and yield of groundnut.

“…Since analyzing the growth rate in area, production and yield of cassava does not account for the relative contributions of area and yield towards the total output change, this paper adapted component/decomposition analysis model to achieve same. The literature is replete with evidence of how this model has been used to estimate relative growth performance of individual output in agricultural production ( Shadmehri, 2010 ; and Rehman et al., 2011 ; Devi et al., 2017 ).…”

This study analyzed the compound growth rate (CGR) and the contributions of yield and area to cassava production output in Nigeria. During the period, TE1970 – TE2018, production followed an upward trajectory from 9.3 million tonnes (1970) to 59.5 million tonnes (2018) while yield oscillated between 7.9tonnes/ha (TE2014) and 11.9tonnes/ha (TE2010). At this period, the CGR per year for yield declined (-0.2%), harvested area increased (10.9%) and production increased (10.6%). The decomposition analysis for the period revealed that, increase in output was largely due to expansion of harvested area (152%) while the interaction between area and yield effect declined production output by 45.8%. Regrettably, during the period, cassava yield also declined production output by 5.8%. The study also found that harvested area has the highest instability index (11.8). In order to further increase and sustain cassava production in Nigeria, intense planting of high yield cassava stems instead of solely expanding cropped area is recommended.

“…Nigeria currently holds the record of the largest producer of cassava in the world but among the seven world topmost current cassava producers. However, it recorded the highest dip in yield performance (-31512 Hg/ha) between the period, 1970-2017(FAOSTAT, 2018. This trend in yield performance (production per hectare) confirms and corroborates the submission that African soils are poor in nutrients to support crop high performance (Tadele and Assefa, 2012;and Fakayode Babatunde and Ajao, 2012).…”

This study analyzed the compound growth rate (CGR) and the contributions of yield and area to cassava production output in Nigeria. In these analyses, the study factored into consideration, in each of the periods, the triennium beginning (TB) and triennium ending (TE). During the period, TB 1970 -TE 1995, yield oscillated between 10.7t/ha (TE 1972 and 10.6 t/ha (TB 1996). At this period, the CGR for yield (0.7%), area (10.8%) and production (11.5%) were positive. The decomposition analysis for the period revealed that increase in output was largely due to expansion of area under cultivation (115%). However, during the period, TB1996 -TE2017, the huge increase in production was largely as a result of interaction between yield and area effects (56.8%) and yield effect (43.8%). At this period, values of CGR for area (9.5%) and production (7.5%) were positive while that of yield was negative (-1.9%). There was a sharp decline from 11.7t/ha (TE 2011) to 7.9t/ha (TE 2014). The interaction between yield and area as well as yield effect compensated for the negative effect of the shrinking land for cassava cultivation. The study recommends that policy strategies geared towards cutting edge scientific methods can achieve optimum cassava production in Nigeria
