Abstract

Sixteen weed control treatments viz. pinoxaden (40 g ha^-1), isoproturon (1250 g ha^-1) alone, isoproturon + pinoxaden (1000 + 40 g ha^-1), isoproturon + pinoxaden (750 + 30 g ha^-1), isoproturon + 2,4-D (1000 + 500 g ha^-1), isoproturon + metsulfuron-methyl (1000 + 4 g ha^-1), pinoxaden + 2,4-D (40 + 1000 g ha^-1), pinoxaden + metsulfuron-methyl (40 + 4 g ha^-1), isoproturon fb pinoxaden (1000 fb 40 g ha^-1), isoproturon fb pinoxaden (750 fb 30 g ha^-1), pinoxaden fb isoproturon (40 fb 1000 g ha^-1), pinoxaden fb isoproturon (30 fb 750 g ha^-1), pinoxaden fb 2,4-D (40 fb 1000 g ha^-1), pinoxaden fb metsulfuron-methyl (40 fb 4 g ha^-1), handweeding (30&60 DAS) and weedy check were evaluated at Palampur to study their effect on nutrient depletion by wheat associated weeds. Avena ludoviciana and Phalaris minor were the major weeds constituting 31 and 19.6%, respectively of total weed dry weight. Lolium temulentum, Vicia sativa, Anagallis arvensis and Coronopus didymus constituted 12.2, 17.1, 10.9 and 9.2%, respectively of the total weed dry weight. Weed control treatments significantly decreased total weed dry weight and thereby NPK depletion by weeds as compared to weedy check. Application of pinoxaden fb MSM (40 fb 4 g ha^-1) being statistically at par wih pinoxaden + MSM (40 + 4 g ha^-1), pinoxaden fb 2,4-D (40 fb 1000 g ha^-1) and hand weeding was significantly superior in reducing the total weed dry matter and nutrition depletion and increasing yield and NPK uptake as compared to the other herbicidal treatments. Weeds in weedy check removed 60.5 kg N, 14.8 kg P and 58.9 kg K ha-1 depriving thereby the wheat crop for that much amount of nutrients. Pinoxaden fb MSM (40 fb 4 g ha^-1) increased NPK uptake by wheat to 88.5, 19.2 and 49.6 kg/ha from 47.5, 9.1 and 29.2 kg/ha, respectively, that under weedy check.

Abstract

Many of the underexploited fruits have nutritional, therapeutic and medicinal values and holds lots of potential to become as new fruit crops. Dheu is among such potential fruits which is neglected from post harvest technological view point. It contains some valuable nutrients such as ascorbic acid and fibre and minerals. In dheu based toffee the acceptability scores was increased with blending with papaya. The product was found to be acceptable during storage upto 90 days. The results revealed that with the addition of papaya the ascorbic acid content of toffee decreased significantly from 31.20 mg/100g to 24.0 mg/100g. With increase in proportion of papaya pulp in dheu pulp, scores for texture of toffee decreased from 8.05 to 7.90. Similarly, the mean scores for overall acceptability for fresh toffee were 8.15 which decreased to 7.89 in toffee prepared with 50:50, dheu and papaya pulp. Although, the overall acceptability scores decreased with storage but the values ranged between liked moderately to liked very much. In the present scenario, where lot of emphasis is being laid on the consumption of health foods, development of such products may help the consumers to harness the nutritional and medicinal properties of such fruits.
