Effect of NPK fertilizer on root, shoot and tiller increment of vetiver (Vetiveria zizanioides (L.) Nash)
Abstract
In this study clumps with two tillers were planted with two treatment T1 (control or without fertilizer) and T2 (with NPK fertilizer). The survival percentage of vetiver clumps was found 96.354±0.354 in control and 97.916±1.802 for NPK fertilizer after 3 months. After 13 months (92.187±1.562) % and (93.750±3.125) % survivability were found in control and NPK fertilizer respectively. After 3 months average tiller increment (nos) were found 2.677±0.252 and 5.877±0.434 respectively in control and with NPK fertilizer. After 13 months the average tiller increment (nos) was found 14.522±0.691 and 21.288 ± 0.477 in control and NPK fertilizer. After 3 months observed value of ‘t’ by independent t-test was 11.022 and P-value is 0.000. After 13 months observed value of ‘t’ by independent t-test was 13.958 and P-value is 0.000. So at 5% significance level, there was a very highly significant difference between control and NPK fertilizer after 3 and 13 months in tiller increment. The average initial root and shoot lengths were 22.022±0.601 cm and 76.755±9.1499 cm during planting time in control. On the other hand, the average initial root and shoot lengths were 22.722±3.548 cm and 65.66±14.611 cm for NPK fertilizer. After 13 months the average root lengths in control and NPK fertilizer were measured 23.123±1.272 cm and 24.422±3.106 cm. The observed value of ‘t’ by independent t-test was 0.669 and P-value was 0.540. The shoot length was measured 143.103±20.378 cm in control and 176.633±24.075 cm in NPK fertilizer. The observed value of independent ‘t’ test was 1.841 and P-value was 0.139. So at 5% significance level there was no significant difference of root and shoots growth in control and NPK fertilizer. After 13 months the mean increment of root and shoot were calculated 1.101 cm and 66.348 cm in control. In NPK fertilizer the mean increment of root and shoot length was calculated 1.7 cm and 110.973 cm.

Amelioration of salinity stress in transplant Aman rice through application of gypsum
Abstract
The experiment was carried out at the farmyard of the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during the period from August 2017 to January 2018 to investigate the ameliorative effect of gypsum application on plant characteristics and yield, under various levels of salinity stress, of transplant Aman rice cv. Binadhan-10. The experiment was designed with three salinity levels such as control (M0), 5 dSm-1 (M1) and 10 dSm-1 (M2) NaCl, two gypsum levels such as control (G0) and 150 kg ha-1 (G1). To ameliorate the salinity stress t, gypsum was applied. Results revealed that the different levels of salinity had a significant adverse effect on plant height, the total number of tillers hill-1, number of effective tillers hill-1, panicle length, number of sterile spikelets panicle-1, 1000-grain weight, number of grains panicle-1, grain yield, straw yield, biological yield and harvest index. All the plants were affected badly when they were exposed to 10 dSm-1 salinity level. At salinity level of 5 dSm-1 grain yield reduction was 37%, which could be minimized to 14% by the application of gypsum. In case of straw yield, A similar amelioration effect was also observed. At 5 dSm-1 the grain yield was more improved from 3.46 t ha-1 to 3.93 t ha-1 when gypsum was applied. The grain yield reduction could further be improved at salinity level of 10 dSm-1 from 65% to 36% with the application of gypsum. At 10 dSm-1 the grain yield was more improved from 1.95 t ha-1 to 2.55 t ha-1 when gypsum was applied. The results of the study conclude that salinity stress could be ameliorated through the application of gypsum @ 150 kg ha-1 in transplant Aman rice cv. Binadhan-10.

Phenotyping of Mustard (Brassica juncea) under the agro ecological condition of Chattogram region
Abstract
Twelve genotypes of Brassica juncea were evaluated at Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Hathazari, Chattogram to find out the superior lines for using in the breeding program to develop a high yielding variety. The first six principal components (PCs) denoted about 92 % of the total variation among genotypes. The number of branches per plant is closely related with no. of siliqua per plant and 1000 seed weight (g) but it had been not strongly related to other traits. Thousand seed weight (g) is closely related with days to 50% flowering and days to maturity but it had been not strongly related to other traits. The no. of seeds per siliqua was positively correlated with length of siliqua and plant height but negatively correlated with other traits. The short vector of seed yield per plot (kg) denotes that it was not strongly correlated with any other traits. The maturity duration among the tested entries ranged from 93-95 days. The entry BJ-11536(12)-3 created the highest siliqua per plant recorded as 198. In contrast, minimum number of siliqua was gained from BJ-11536(9)-6 which was noted as 104. The highest seed per siliqua noted as 16 was observed in BJ-11536(12)-3 followed by 15 seeds per siliqua in BJ-11536(7)-2 and the lowest seed per siliqua documented as 12 was obtained from the entries BJ-10-10104(y), BJ-11536(9)-2 and BARI Sarisha 11. The entry BJ-11536(12)-3 provided the highest yield of 1.79 t/ha followed by 1.42 t/ha in BJ-2014-y02 and BJ-2104-y05. Three genotypes namely BJ-11536(12)-3, BJ-2014-y02 and BJ-2104-y05 can be selected to be used as parental materials in the breeding program.

Effect of herbicides on weed control and performance of wheat
Abstract
An experiment was conducted to evaluate the weed control efficiency and wheat performance as affected by different types of herbicides at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from November 2016 to March 2017. The experiment was laid out in a randomized complete block design and consists of four replications and eleven treatments viz. no weeding (T0), L–Quat 20 SL as pre-emergence herbicide at 2 DAS (T1), Affinity 50.75 WP as post-emergence herbicide at 23 DAS (T2), T1 + T2 (T3), T3 + hand weeding at 40 DAS (T4), Panida 33 EC as pre–emergence herbicide at 2 DAS (T5), U–46D fluid as post-emergence herbicide at 23 DAS (T6), T5 + T6 (T7), T7 + hand weeding at 40 DAS (T8), T5 + T1 + T5 + T6 (T9), T5 + T2 (T10). Fourteen weed species namely Echinochloa cruss–galli, Echinochloa colona Cynodon dactylon, Digitaria sanguinalis, Paspalum distichum, Parapholis incurva, Cyperus rotundus, Chenopodium album, Polygonum hydropiper, Alternanthera sessilis, Oldenlandia corymbosa, Vicia sativa, Physalis heterophylla and Commelina diffusa were infested the experimental field belonging to 9 families where six were grasses, one was sedge and seven were broadleaves. Five most dominant weed species based on importance value in unweeded conditions at 15 DAS were Polygonum hydropiper > Cyperus rotundus > Echinochloa colona > Chenopodium album > Cynodon dactylon. But at 40 DAS and harvest the rank and order of above mentioned five most dominant weed species was differed and Commelina diffusa and Echinochloa cruss–galli were found at 40 DAS and at harvest, respectively instead of Chenopodium album. Both the weed density and dry weight were lowest in T8 treatment followed by T4 treatment at 15 DAS, 40 DAS and harvest. In case of weed control efficiency, these treatments along with T3, T4, T7, T8, T9 and T10 treatments produced the best result as “good control” in comparison to others which produce “fair control” efficiency at 40 DAS. But at harvest, only T4 and T8 produced as “good control” efficiency. The yield and yield components of BARI Gom 24 (Prodip) were statistically significant except the number of non–effective tillers hill–1. The highest grain yield (5 t ha–1) was recorded in the treatment T8 which was statistically identical to the treatment T4 due to having higher number of effective tillers hill–1, higher number of spikelets spike–1, higher number of filled grains spike–1 and 1000-grain weight. The lowest grain yield (2.9 t ha–1) was observed from the control (no weeding) treatment. The highest net returns (61473tk) and BCR (1.64) were obtained under the weed control T8 treatment. It can be concluded that the treatment T8 (Panida 33EC pre-emergence + U 46 D Fluid post–emergence + hand weeding once at 40 DAS) could be applied as the promising practice in wheat cultivation in terms of effective weed control, highest yield, highest economic returns and highest BCR.

Five most dominant weed species based on importance value in unweeded conditions at 15 DAS were Polygonum hydropiper > Cyperus rotundus > Echinochloa colona > Chenopodium album > Cynodon dactylon. But at 40 DAS and harvest the rank and order of above mentioned five most dominant weed species was differed and Commelina diffusa and Echinochloa cruss–galli were found at 40 DAS and at harvest, respectively instead of Chenopodium album. Both the weed density and dry weight were lowest in T8 treatment followed by T4 treatment at 15 DAS, 40 DAS and harvest. In case of weed control efficiency, these treatments along with T3, T4, T7, T8, T9 and T10 treatments produced the best result as “good control” in comparison to others which produce “fair control” efficiency at 40 DAS. But at harvest, only T4 and T8 produced as “good control” efficiency. The yield and yield components of BARI Gom 24 (Prodip) were statistically significant except the number of non–effective tillers hill–1. The highest grain yield (5 t ha–1) was recorded in the treatment T8 which was statistically identical to the treatment T4 due to having higher number of effective tillers hill–1, higher number of spikelets spike–1, higher number of filled grains spike–1 and 1000-grain weight. The lowest grain yield (2.9 t ha–1) was observed from the control (no weeding) treatment. The highest net returns (61473tk) and BCR (1.64) were obtained under the weed control T8 treatment. It can be concluded that the treatment T8 (Panida 33EC pre-emergence + U 46 D Fluid post–emergence + hand weeding once at 40 DAS) could be applied as the promising practice in wheat cultivation in terms of effective weed control, highest yield, highest economic returns and highest BCR.

Lemon grass oil: effect on physico-chemical properties and postharvest life of banana cv. Amritasagor
Abstract
Banana undergoes various diseases at the entire stages of its life. The most important post-harvest disease of Banana is Anthracnose which causal organism is Colletotrichum gloesporioides. The objective of the current research work was to test the effectiveness of the use of lemon grass extract oils (Citrus medica) to minimize the postharvest losses commenced by anthracnose (Colletotrichum gloeosporioides) disease in banana fruits. In this experiment, the antifungal activity of essential oils were assayed under in vitro and in vivo condition by post-harvest application of lemon grass oil (20%) on banana fruits with fungicidal treatment (diphenochonazol) and sterilized water treatment as a control. Single-factor experiment was carried out in a completely randomized design (CRD) with five replications at postharvest analysis laboratory, Department of Horticulture, Patuakhali Science and Technology University, Bangladesh. Among the physico-chemical parameters; pH, TSS and sugar contents increased significantly whereas titratable acidity and ascorbic acid decreased during post-harvest storage period in all treated and untreated fruits. There was significant increasing tendency was obtained in relation to disease incidence and disease severity in control fruits compared to other lemon grass extract treated fruits and fungicide treated fruits. Among the physico-chemical parameters, lemon grass oil treated fruits produced significantly the highest pH (5.99), lowest total soluble solids (19.24%), total sugar (9.04%), reducing sugar (5.48%), titratable acidity (0.52) and ascorbic acid content (9.04 mg/100g) compared to control. Postharvest disease was severe at 12 days of storage; it was maximum (100%) in distilled water treated fruits and minimum in lemon grass oil treated fruits (42.20%). Based on storage performance, lemon grass extract treated fruits resulted in the longest shelf life (12.33 days) and shortest (6.33 days) was recorded in control fruits. This experiment’s findings recommend the application of lemon grass essential oils @20% on ‘Amritasagor’ Banana prior to storage to improve and extend the postharvest storage.
