Abstract
A field experitnent was conducted during the rainy (khar~j) season of 1988 and 1989 under raitlfed con- dition, to study the effect of soil-moisture conservation and weed-control practices on N, P and K uptake, and yield of pearlmillet [Pennisetionglaucum (L.) R. Br. emend. Stuntz]. Moisture-conservatio~~ practices proved beneficial only in scanty rainfall year of 1989. Straw n~ulch either used in flat bed or ridge and fi~r- row seed-bed caused significant reduction in dry-matter accur~~ulatlot~ and N, P and K depletion by weeds compared with flat bed and ridge and furrow alone. However, grain yield and nutrient uptake by pearltnillet improved significantly with ridge and furrow + straw ~l~ulch and ridge and furrow alone. Hand-weeding and atrazine @ 0.50 k g h were found most efficient treatn~ents in reducing dry-matter accutnulation and nutri- ent depletion by weeds in both years and in increasing gain yield and nutrient uptake by pearln~illet only in good raitlfall year of 1988.
