EFFECT OF MICRONUTRlENTS WIm DIFFERENT LEVELS OF NPKS FERTILIZER ON SEED YIELD AND QUALITY OF ONION HOSSAIN, MD. MONIR An experiment was conducted at the Agronomy Research field of Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2013 to April, 2014 with a view to determine the effect of micronutrients (Zn, B and Mn) with different levels of NPKS fertilizers on yield and 'quality of onion (Allium cepa L.) seed. The experiment was conducted with four levels of micronutrients viz. M,= ZnoBoMno kglha, M2= ZI4BIMn2 kglha, M3= Zfi6B2Mn3 kg/ha and ~= ZnsB3MItt kglha and three doses of NPKS fertilizers viz. FI= N57P2IK)9S9kglha, F2= NlI4P42K7sS,skglha and F3 =NI7JP63KII7~7 kglha. The experiment was laid out in a Randomized Complete Block Design with 12 treatment combinations and replicated thrice. Application of micronutrients and different doses ofNPKS fertilizers increased plant height and number of leaves per plant at different growth stages, days required to first bolting, number of umbels/plot, days required to first anthesis, number of seeds per umbel, weight of seeds per umbel, seed yield per plant, per plot and per hectare, weight of 1000 seeds, percentage of seed germination and seed vigour index. The highest seed yield (819.9 kglha), percent germination of seeds (88.89010) and seed vigour index (2084.77) were recorded from M) treatment and the lowest seed yield (787.4 kglha), percent germination of seed (84.44%) and seed vigour index (1724.26) were observed in M, treatment The positive effects of micronutrients were found in order ofM3> ~> M2> M,. The F2 treatment produced the highest seed yield (957.6 kglha), percent germination ofseed (90.67%) and seed vigour index (2258.20) and FI treatment produced lowest (116.6 kg/ha, 85.25% and 1121.05 respectively). The positive effects were found in order of F2> F» Fl. Among the treatment combinations, M)F2 produced the highest seed yield (1027.0 kg/ha), germination of seed (94.00%) and seed vigour index (2537.33) and M.F, produced the lowest yield (734.4 kg/ha), germination of seed (82.67%) and seed vigour index (1488.66).

POTASSIUM AND MULCH EFFECTS ON GROWTH, YIELD, QUALITY AND STORAGE PERFORMANCE OF POTATO PULOK, MD. ASHRAFUL ISLAM A field experiment was conducted at the Agronomy research field of Sher-e-Bangla Agricultural University. Dhaka. during the period from November 2013 to Jul' 2014, to study the potassium and mulch effects on growth. yield, quality and storage perlbrmance of potato. The experiment comprised as two thetors: Factor A: potassium: 4 levels: K1 - No Mop. K, - 200 kg MoP ha* K1 - 250 kg MoP ha". K 4 - 300 kg MoP ha'' and Factor B: different mulches: M, - soil mulch. M - rice straw. M 3 - vater hyacinth and M4 - saw dust. 'ftc experiment was laid out in a split-plot design with three replications. The result revealed that potassiim and/or mulch materials had significant effects on most of the growth. yield and quality parameters studied in this experiment. Results revealed that. tuber yield, dry matter content. specific gravity and total soluble solids. gradually increased with increasing up to application of 250 kg MoP ha" and thereafter decreased with increasing potassium level. Among the different niulch materials, rice straw exhibited better perfonnance in respect oL'vield. dry matter content. specific gravity', total soluble solids in tuber compared to those of other mulches. Among the sixteen treatment combinations. the application of 250 kg MoP ha 1 along with rice straw mulch produced maximum tuber yield (28.89 t ha''). highest dry matter content (24.33 %). maximum specific gravity (1.13 g em') and optimum total soluble solids (4.20 % brix). This combination also demonstrated better performance in ambient storage condition. [he max imuni cosi benent ratio (2.61 ) were 101111(1 when application ol' 250 kg MoP ha' s"itli rice straw mulch. Although the combination of K3M2 showed better grovth. yield, quality performance but K 1M3 also demonstrated statistically similar results. So. rice straw mulch or water hyacinth are suitable for prodticing good quality potato along with applying 250 kg Mo? ha".

INFLUENCE OF SOWING TIME AND PRIMING ON GROWTH YIELD AND SEED QUALITY OF CHICKPEA HUSNAIN, MD. SAFAYAT A field experiment was conducted at the Agronomy research field of Sher-e-l3angla Agricultural University, Dhaka, during the period from November 2013 to March 2014 to study the eflèct of sowing time and seed treatment with GA 3 on growth, yield and quality of chickpea. The experiment comprised as two factors: sowing date - 3 times: l sowing date: 2d sowing date: 29i November -- S2 and3 sowhig date: 9th 19Ih November - S,. December - S3 and seed treatment with gibberellic acid (GA3 ) - 5 levels: GA3 75 ppm - T, GA3 ISO ppm - T2, GA3 225 ppm - 1'). GA3 300 ppm - T 4 and hydro-priniing - T 5 . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The result indicated significant variations in date of emergence, date of (irsi flowering, date of 50% flowering, plant height, number of branches plant 4 , total dry matter, number of pod plant', date to pod maturity, pod length. weight of 1000 seed, grain yield. stover yield, biological yield, harvest index. germination percentage and vigor index due to sowing time and/or seed treatment with GA 3. Among the treatment combinations, the tallest plant and dry matter content were recorded in S2T3 irrespective of growing time. This combination also exhibited maximum number of pods plant", the longest pod length and maximum number of seeds pod", whereas required minimum duration for pod maturity. The maximum weight of 1000 seed, the highest grain yield, harvest index and also maximum germination percentage and vigor index were found, when chickpea was sown on 29th November and treated with 225 ppm GA3.

OPTIMIZING THE PRODUCTIVITY AND PROFITABILITY OF ONION SEED BY APPROPRIATE MANAGEMENT OF ORGANIC MANURE AND BULB SIZE RAHMAN, MD. ASADUR An experiment was conducted in the central research fam of Sher-e-Bangla Agricultural University. Dhaka. durimi the period from October 2013 to March 2014. to study optimizing the productivity and profitability of onion seed by appropriate management of organic manure and bulb size. The experiment consisted with two factors. Factor A: Four combination of organic manures such as M1 = control. M2 — IS tfha Cowdung4-l0 vim Poultry manure. M 3 15 I/ha Cowdung-'-2.2 tiha Mustard oil cake and M4 15 i/ha Cowdung±l0 t/ha Poultry manure 12.2 t/ha Mustard oil cake. Factor B; Four sizes of onion bulbs such as S1 =2g. S , 4g. 5; = 6g and S1 = 8g. The experiment was laid out in a Randomized Complete Block Design with 16 treatment combinations. Application of' different organic manures and bulb size significantly influenced by plant height and number of leaves per plant at different growth stages ., days required to first bolting. number of umbels/plant, days required to first anthesis. number of seeds per umbel, seed yield per plant, per plot and per heclare, weight of 1000 seeds and seed vigor index. But it did not show any significant effect on seed germination (%).The maximum seed yield 567.3 Kg/ha with net income (1k 126.07.65) and BCR (2.74) was obtained from M 4S4 treatment combination which was statistical]' identical to M 4S3 treatment combination and the minimum seed yield 185.3 Kg/ha with net income (11 245086.2) and BCR (1.61) was observed from M 1 51 treatment combination. Thc BCR (2.94) from Mi S treatment combination is higher than BCR (2.74) from M 1 S1 treatment combination. So economic analysis revealed that the M.,S 3 treatment combination appeared to be the best for achieving higher productivity and profltahi I ity ofonion seed production.
