Other claims from this paper (16)
- Observation Maximum above ground biomass of desi chickpea in the first season was 5.06 tonnes per hectare.
- Observation Maximum above ground biomass of desi chickpea in the second season was 4.37 tonnes per hectare.
- Intervention effect Applying 60 kg N produced 62% more above-ground biomass (DM) in chickpea than no N application in the first season.
- Intervention effect Applying 60 kg N produced 68% more above-ground biomass (DM) in chickpea than no N application in the second season.
- Association Above ground biomass of chickpea responded curvilinearly to added levels of N, with high coefficients of 0.944 and 0.989 in the two seasons, which the authors say signifies the possibility of increasing biomass further.
- Observation Maximum grain yield of chickpea in season I was 2.57 t per hectare.
- Observation Maximum grain yield differed between season I and season II of chickpea by 54.8%.
- Mechanism The authors attribute the higher chickpea grain yield in season I to higher rainfall (235 mm versus 176.8 mm in season II).
- Association Above ground biomass and grain yield of chickpea responded linearly to increasing plant population density, with regression coefficients over 0.993 in both seasons.
- Observation Harvest indices of chickpea ranged between 0.42 and 0.72.
- Observation Applying 20 kg N produced a harvest index of about 0.6 in chickpea in season I.
- Observation Applying 20 kg N produced a harvest index of about 0.5 in chickpea in season II.
- Intervention effect Increasing planting population up to approximately 105,000 plants per hectare increased the chickpea harvest index to over 0.6 in season I.
- Intervention effect Increasing planting population up to approximately 105,000 plants per hectare increased the chickpea harvest index to over 0.41 in season II.
- Intervention effect Increasing plant density beyond 110,000 plants per hectare caused a decline in the rate of increase in harvest index of chickpea.
- Recommendation The authors conclude chickpea can be successfully grown in Naivasha in the February to June and June to October seasons.
