The investigation was carried out to study the “Effect of integrated nutrient management practices on yield and quality of sweet potato [Ipomoea batatas (L.) Lam] cv. Kanjangad” at Elavuvilai village, Kanyakumari District, Tamil Nadu during Kharif season of 2020. The experiment was laid out in randomized block design with nine treatments replicated thrice. Sweet potato vine cuttings of about 15 cm with 4 nodes were used for the study. The treatments comprised of two levels of recommended dose of fertilizers (RDF - 40:80:120 kg NPK ha-1) viz., 50 and 100% along with FYM, poultry manure, gibberellic acid and seaweed extract. The treatments comprised of half dose of nitrogen and full doses of phosphorous and potassium were applied as basal and remaining half dose of nitrogen was applied at 60 days after planting. Organic inputs viz., FYM (25 t, 12.5 t ha-1), poultry manure (5 t, 2.5 t ha-1) as were applied as basal application, gibberellic acid (200 ppm) and seaweed extract (2%) were applied as foliar application at 40, 55 and 70 days after planting were also used. The observations were recorded at 180 days after planting. The results indicated that the maximum values for yield parameters viz., number of tubers plant-1 (3.02 g), tuber length (19.02 cm), tuber girth (15.58 cm), tuber weight (138.36 g), tuber dry weight (66.73 g), tuber yield [plant-1 (417.84 g),  plot-1 (12.18 kg), hectare-1 (30.45 t)], whereas quality parameters such as total soluble solid (9.210 Brix) and starch content (12.24%) of tuber, post harvest soil available nutrient (245.00 N; 21.93 P and 278.00 K kg ha-1), maximum net income (Rs. 5,16,050) and B: C ratio (3.23)  were recorded in the plots which received 50% RDF + FYM 12.5 t ha-1 + Poultry manure 2.5 t ha-1 + Seaweed extract 2% (T9). This was followed by (T6) 50% RDF+ FYM 12.5 t ha-1 + Poultry manure 2.5 t ha-1 + GA3 200 ppm.

Yield And Quality

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to study the yield and quality of aromatic fine rice as affected by variety and nutrient management during the period from June to December 2013. The experiment comprised three aromatic fine rice varieties viz. BRRI dhan34, BRRI dhan37 and BRRI dhan38, and eight nutrient managements viz. control (no manures and fertilizers), recommended dose of inorganic fertilizers, cowdung at 10 t ha-1, poultry manure at 5 t ha-1, 50% of recommended dose of inorganic fertilizers + 50% cowdung, 50% of recommended dose of inorganic fertilizers + 50% poultry manure, 75% of recommended dose of inorganic fertilizers + 50% cowdung and 75% of recommended dose of inorganic fertilizers + 50% poultry manure. The experiment was laid out in a randomized complete block design with three replications. The tallest plant (142.7 cm), the highest number of effective tillers hill(10.02), number of grains panicle (152.3), panicle length (-1 -122.71cm), 1000-grain weight (15.55g) and grain yield (3.71 t ha-1) were recorded in BRRI dhan34. The highest grain protein content (8.17%) was found in BRRI dhan34 whereas the highest aroma was found in BRRI dhan37 and BRRI dhan38. The highest number of effective tillers hill(11.59), number of grains panicle (157.6), panicle length (24.31 cm-1-1) and grain yield (3.97 t ha-1) were recorded in the nutrient management of 75% recommended dose of inorganic fertilizers + 50% cowdung (5 t ha-1). The treatment control (no manures and fertilizers) gave the lowest values for these parameters. The highest grain yield (4.18 t ha-1) was found in BRRI dhan34 combined with 75% recommended dose of inorganic fertilizers + 50% cowdung, which was statistically identical to BRRI dhan34 combined with 75% of recommended dose of inorganic fertilizers + 50% poultry manure and the lowest grain yield (2.7 t ha-1) was found in BRRI dhan37 in control (no manures and fertilizers). The highest grain protein content (10.9 %) was obtained in the interaction of BRRI dhan34 with recommended dose of inorganic fertilizers which was as good as that of BRRI dhan38 and 75% of recommended dose of inorganic fertilizers + 50% poultry manure. The highest aroma was found in BRRI dhan38 combined with 75% recommended dose of inorganic fertilizers + 50% cowdung.J. Bangladesh Agril. Univ. 12(2): 279-284, December 2014

Study Application

The nutritional need of acid lime is unique and differs from other fruit crops as it has continuous flowering and heavy fruiting habit. An experiment was conducted with the key objective of studying the effect of integrated nutrient management system on yield and quality of acid lime, variety PKM 1. In this study, application of 100 per cent recommended dose of fertilizers (600:200:300 g NPK plant-1 year-1 )+ Azospirillum (100g plant-1) + phosphobacteria (100g plant-1) + Arbuscular Mycorrizhal Fungi (500g plant-1) + Trichoderma harzianum (100g plant-1) has showed a superior performance regarding yield, yield attributing components and quality attributes of acidlime.
