PHENOTYPIC EXPRESSION OF DIFFERENT TRAITS AGAINST THE PREVALANCE OF MAJOR DISEASES IN FINE RICE
(HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2009) HABIBA, UMME; Professor Bhabendra Kumar Biswas
An experiment was carried out at the experimental field of Department of Genetics and Plant Breeding, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period from July to December 2008 to study the phenotypic expression of different traits against the prevalence of major diseases in fine rice. The experiment was laid out in a Randomized Complete Block Design with three replications provided 7 genotypes of fine rice. The results of the investigation revealed that significant variation were found among the genotypes for the characters tillers per hill and 1000- grain weight (g). On the other hand, variation was observed both for genotype and environment against effective tillers per hill, spikelets per panicle and sterility percentage (“%).High co-heritability was estimated in 1000-grain weight and number of affected tillers by brown spot per hill with yield. Number of affected tillers by brown spot per hill was highly environmentally influenced character. On the contrary, percent of affected tillers by sheath blight per hill was less influenced by environment. Effective tillers/hill, panicle length, spikelets/panicle and 1000-grain weight showed significant and positive correlation with yield. Selection would be effective for increasing grain yield for the characters plant height, effective tillers per hill, spikelets per panicle and panicle length. Ranzit and Zira were showed high degree of disease resistance against brown spot, bacterial leaf blight and sheath blight. Varieties seemed to be easy to improve were Katari, Badshabhog and Sanla. The highest yield was obtained in Ranzit (4.603 t/ha).
RESPONSE OF GROWTH, FLOWERING AND YIELD OF BITTER GOURD INFLUENCED BY NPK FERTILIZERS AND NAA
(DEPARTMENT OF HORTICULTURE, 2018) HABIBA, UMME
The present study was conducted at the Horticultue farm of Sher-e-Bangla Agricultural University to study the response of growth, flowering and yield of bitter gourd influenced by NPK fertilizers and NAA during the period of March to June, 2018. Four levels of NPK fertilizers viz, N 0 ii (N 0 P 0 K 0 kg ha -1 ), N 1 (N ), N 2 (N 35 P 20 K 25 kg ha -1 ) and N 3 (N 45 P 30 K 35 kg ha -1 25 P 10 K 15 ) and three levels of NAA viz, H (0 ppm NAA), H 1 (50 ppm NAA) and H (100 ppm NAA) were laid out in Randomized Complete Block Design (RCBD) with the three replications. Treatment combination of NPK fertilizers and NAA, the highest number of branches plant 2 -1 (14.20), number of male flowers (33.20), number of female flowers (28.20), percent fruit set (33.32%), fruit length (12.62 cm), fruit diameter (8.56 cm), fruit weight plant (1.47 kg), number of fruits plant -1 (20.40), fruit weight plot -1 1 ) were achieved from the treatment combination of N -1 kg ha (2.94 kg) and fruit yield (24.52 t ha 2 H . The lowest fruit yield (8.60 t ha -1 ) was recorded from N 0 H 0 2 . In terms of economic analysis, the highest BCR (3.01) was obtained from the treatment combination of N 2 H ) whereas the lowest BCR (1.14) was obtained from N 0 H 0 .
