Growing Conditions

Kochia scoparia naturally invades distributed soils in the Brown soil zone of the Canadian Prairies and offers potential as a forage crop in saline environments. A 3-yr study conducted on severely saline soil near Swift Current, Saskatchewan, compared kochia production resulting from fall (natural- and implement-seeded) and spring (early- and late-seeded) treatments. Late spring-seeded crops produced, on average, 5.4 t of dry, shoot biomass per ha per yr. Early spring and fall-seeded kochia (naturally or implement-placed) yielded between 5.4 and 10.9 t ha−1. Of the nine comparisons between forage yields from fall and spring seedings, six favored fall over spring, two were equal, and one produced more forage from early spring seedings than from the naturally-seeded fall treatment. The late spring treatment consistently produced the least forage. Fall seedings exhibited a greater potential for forage production because fall-seeded plants usually established early in the growing season and in sufficient number to fully exploit soil and water resources when conditions became favorable and effective rooting depths were not restricted by concentrated salt layers. When drier growing conditions prevailed, the lower plant densities associated with early spring seedings tended to minimize plant competition and foster greater forage production. Key words: Kochia forage, seeding dates, salinity, Kochia establishment, Kochia agronomy

Digestible Protein

A trial was conducted to determine the nutritive value for sheep of kochia (Kochia scoparia L. Schrad) grown on saline soil and harvested at the early seed stage and the full bloom stage of maturity. There was a significant decrease in digestible organic matter intake (DOMI) and digestible crude protein intake (DCPI) with increasing kochia maturity (31.6 vs. 23.2 g DOMI kg−0.75 (SE = 0.6; P < 0.05) and 4.22 vs. 1.41 g DCPI kg−0.75 (SE < 0.001; P < 0.05)). Early cut kochia appears to be at least equivalent in digestible energy to alfalfa, but lower in digestible protein. Key words: Kochia, maturity, nutritive value, sheep

Kochia scoparia (L.) Schrad. naturally invades mechanically disturbed soils in the Brown and Dark Brown soil zones of the Canadian Prairies and offers potential as a forage crop in saline environments. A 3-yr study conducted on severely saline soil (~ 11 dS m−1) near Swift Current, Saskatchewan, evaluated the production of kochia forage and plant-N uptake following applications of 0, 56, 112 and 168 kg N ha−1 of ammonium nitrate. The yield response in aboveground, dried forage (Y) followed a curvilinear function based on the quantity of nitrogen applied (N): Y = 4740 + 38.5N − 0.121N2. The N-fertilizer requirement to produce 7500 kg ha−1 of dried forage (96% of the function maximum) equalled 110 kg N ha−1 and reflected average growing conditions at the study site during 1987–89. The kochia assimilated protein N (Kjeldahl) within its tissue in direct proportion to the fertilizer dosage applied, reaching theoretical maxima which varied yearly: 18 g kg−1 in 1987, 12 g kg−1 in 1988 and 22 g kg−1 in 1989. Although NO3-N concentrations increased with each addition of fertilizer N, the maximum accumulation of NO3 N (0.5 g kg−1) among all the tests and treatments was within the safe limit of 1.1 g kg−1 to avoid livestock poisoning. The efficiency with which the fertilizer N was assimilated by the kochia ranged between 44 and 69% over the test years and fertilizer treatments.
