The seeds were sown on the 4<sup>th</sup> of May 2016. Harvesting was done in August 2016. A total area of 250m<sup>2</sup> was cleared and prepared in to a Randomized Complete Block Design (RCBD). Each block was divided into nine ridges. Eight fertilizer treatments: inorganic (NPK 15:1515, NPK 11:11:22), organic (Pig dropping, Poultry dropping), composite (four bi-combinations of the animal and NPK-based fertilizer) and a control treatment were randomly assigned to each ridge per block. General agronomic practices were adopted from local farmers. Data were collected on vegetative and reproductive parameters. Correlation analysis was also evaluated between parameters. This was followed by principal component analysis with varimax rotation. Principal components were selected based on eigen value criteria – a component was selected if its eigen value was greater than 1. All analyses were done using PAST (ver. 3.26b) Analysis revealed significant correlations between some vegetative and reproductive parameters notably between emergence and plant height (r = 0.45, <em>P </em>&lt; 0.05), emergence and plant harvested (r = 0.867, <em>P</em> &lt; 0.05), and between plant cover and plant height (r = 0.546, <em>P</em> &lt; 0.05). According to the eigen value criteria (eigen value &gt; 1.0), 4 principal components were retained from organic and inorganic nutrient sources each, and 3 principal components were retained from composite nutrient source. Reproductive parameters were more aggregated in the first principal component for organic nutrient source, accounting for 35.87% of all variations while they were more aggregated in the second principal component (25.61%) from inorganic nutrient sources. From the composite nutrient source, the reproductive and vegetative parameters were almost equally distributed between the first (31.80%) and second (27.82%) principal components. In this study, that varied nutrient sources (organic. Inorganic and composite) affects Irish potato differently. Consequently, both organic and inorganic nutrient sources should be seen as synergistic and not mutually exclusive for holistic production of Irish potato.</p> Tange Denis Achiri, Abdulai Assan Nkuh, Divine Nsobinenyui, Dominic Kumbah Njualem ##submission.copyrightStatement## http://journalijpss.com/index.php/IJPSS/article/view/30253 Tue, 24 Mar 2020 00:00:00 +0000 Performance Evaluation of Some Selected Okra Genotypes http://journalijpss.com/index.php/IJPSS/article/view/30254 <p>The experiment was conducted at the experimental farm, Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur to evaluate the Performance of Selected Okra Genotypes for Growth and Yield Parameter. The study was laid out in Randomized Complete Block Design (RCBD) from March 2008 to July 2008. The studied characters were plant height, branches plant<sup>-1</sup>, days to first flowering, days to first fruit harvest, picking duration, fruit length, fruit diameter, fruits plant<sup>-1</sup>, fruit weight, picking duration, yield plant<sup>-1</sup>, yield hectare<sup>-1</sup> and virus infestation. The results showed that studied genotypes differed significantly regarding all the character studied. The maximum plant height (173.92 cm), days to first flowering (40.00), days to first fruit harvest (9.33), picking duration (49.33) found in Green glory genotypes while maximum branches plant<sup>-1 </sup>(2.50) found in Seminis. The highest fruit length (15.85 cm) and fruit weight (17.81 g) was recorded in IPSA okra, fruit diameter (18.54 mm) in Green glory, fruits plant<sup>-1</sup> (15.27), yield plant<sup>-1</sup> (250.24 g), yield hectare<sup>-1</sup> (13.73 t ha<sup>-1</sup>) in Jhalak while lowest virus infestation also recorded in Jhalak in all the&nbsp; studied days after sowing. From the present investigation, it can be concluded that the genotypes ‘Jhalok’ and ‘BARI Dherosh 1’ performed better among the studied genotypes and can be recommended for commercial cultivation.</p> A.

It is the largest reservoir of terrestrial carbon. Here, an investigation was carried for the assessment of Soil Organic Carbon in three different density classes of Oak forest of Chakrata (Distt. Dehradun), Itarna (Distt. Tehri Garhwal) and Lansdowne (Distt. Pauri Garhwal) forest divisions of Uttarakhand. Three soil samples from each forest system at 0-30 cm depth were collected from each density to assess soil organic carbon stock. A total of 81 soil sample were collected in three seasons. In summer season among all three division maximum Soil Organic Carbon was assessed in Chakrata dense forest division (81.65 t ha<sup>-1</sup>), followed by moderate forest (47.66 t ha<sup>-1</sup>) and open forest (37.68 t ha<sup>-1</sup>) of Chakrata forest division. In Lansdowne forest division maximum SOC was found in dense forest (79.82 t ha-1) followed by moderate (48.53 t ha-1) and open forest (35.37 t ha<sup>-1</sup>) respectively. A similar trend was reported in case of Itarna forest division. Where (78.47 t ha<sup>-1</sup>) come up to maximum reservoir of SOC followed by moderate forest (46.50 t ha-<sup>1</sup>) and open forest (34.52 t ha<sup>-1</sup>) respectively. In rainy season among all three division maximum Soil Organic Carbon was assessed in Chakrata dense forest division (66.24 t ha<sup>-1</sup>), followed by moderate forest(45.62 t ha<sup>-1</sup>) and open forest (29.53 t ha<sup>-1</sup>) of Chakrata forest division. In Lansdowne forest division maximum SOC was found in dense forest (75.48 t ha<sup>-1</sup>) followed by moderate 48.65 t ha<sup>-1</sup>) and open forest (22.36 t ha<sup>-1</sup>) respectively. Similar trend was reported in case of Itarna forest division.In winter season among all three divisions maximum Soil Organic Carbon was assessed in Chakrata dense forest division (81.89 t ha<sup>-1</sup>), followed by moderate forest (56.62 t ha<sup>-1</sup>) and open forest (32.32 t ha<sup>-1</sup>) of Chakrata forest division. In Lansdowne forest division maximum SOC was found in dense forest (81.90 t ha<sup>-1</sup>) followed by moderate (57.43 t ha<sup>-1</sup>) and open forest (35.99 t ha<sup>-1</sup>) respectively. A similar trend was reported in case of Itarna forest division. This study reveals that in the Soil Organic Carbon is maximum in the dense forest followed by moderate and open forest which could be possibly due the more flora and fauna in the dense forest followed by moderate and open forest. Possibly the activities of flora and fauna lead to the addition of more carbon content in the soil. The study demonstrated similar trends of SOC in three different dense, moderate and open density classes of Oak forest. These outcomes of the study may explore the possibility to improve the scientific basis of forest management and land use in the near future.</p> Antrix Soni, Parul Bhatt, Usha Devi ##submission.copyrightStatement## http://journalijpss.com/index.php/IJPSS/article/view/30255 Thu, 09 Apr 2020 00:00:00 +0000
