During the survey, data was recorded on one hundred fifty two (152) walnut trees growing in different areas of Kashmir valley. Remarkable variability was observed in seedling walnut trees for different morphological, nut and kernel characters. Similarly, variations were also reported for other characters viz., tree vigour, growth habit, branching habit, leaflet shape, shoot colour, nut shape, shell texture, shell colour, shell seal, shell strength, shell integrity, kernel shrivel and kernel colour. studied the nut length varied from 30.0-60.0 mm with a population mean of 55.62 ± 3.28mm. The phenotypic and genotypic variance was 605.14 and 427.56, corresponding to their co-efficients of variation to the extent of 44.25 and 37.17 per cent, respectively. Heritability (broad sense) and expected gain (% of the mean) was 70.65 per cent and 64.36, respectively. Nut weight revealed a population mean of 14.48 ± 2.54 g with a range of 8.50-30.0 g. The phenotypic (18.785) and genotypic (12.760) variance when translated into their respective co-efficients of variation gave the estimate of 27.98 and 23.02 per cent, respectively. Broad sense heritability was 67.9 per cent and expected genetic gain (% of the mean) as 39.15.","PeriodicalId":411017,"journal":{"name":"INTERNATIONAL JOURNAL OF FORESTRY AND CROP IMPROVEMENT","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122045837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, an attempt was made to characterize and compare the variations of leaf, stem and petiole morphology of various Populus deltoides Bartr. crosses. In order to achieve these objectives, twelve crosses of P. deltoides Bartr. were evaluated for different parameters. On the basis of various morphological characteristics the results revealed that each cross has a distinct color pattern of leaves. Different colors observed in these crosses varied from yellow green to green. Distinct nature of the stem altitude was found. Anthocyanin distribution of leaves was also found. In this study, the morphological traits of leaves and petiole provided discriminatory grounds for separating various populations of P. deltoides Bartr. crosses. Character of stem studies indicates that different crosses vary considerably with regard to shape, colour and nature.","PeriodicalId":411017,"journal":{"name":"INTERNATIONAL JOURNAL OF FORESTRY AND CROP IMPROVEMENT","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122826147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Performance of inter specific cotton hybrids under various plant geometries and nutrient levels","authors":"H. Meena, B. Kumhar","doi":"10.15740/has/ijfci/8.1/49-52","DOIUrl":"https://doi.org/10.15740/has/ijfci/8.1/49-52","url":null,"abstract":"Cotton is known as white gold and queen of fibers. It is an important cash crop of global significance which plays a dominant role in world agriculture and industrial economy. India is important grower of cotton on a global scale. The cotton productivity in 2016-17 has 568 kg/ha with an area of 105 lakh ha and production 351 lakh bales each 170 kg [1]. Plant geometry is having greater importance in cotton cultivation. Bt cotton crop may be producing excessive vegetative growth at wider plant geometry and excessive reproductive growth at close plant geometry. However, numerically lower monopodial with closer plant geometry and lower sympodial with wider plant geometry were observed indicating more period under vegetative growth with wider spacing [2]. Closer plant geometry also recorded higher seed cotton yields [3]. Cultivar selection, a key management component in any cropping system, is even more critical in various crop geometry of cotton production. While high yield potential is a predominant consideration, maturity, plant size, the transgenic present, and fiber properties are also major factors to consider [4]. The maximum exploitation of these genotypes can be achieved only after determining their optimum planting densities in comparison to recommended cotton varieties. In general, it was observed that lower plant densities produces high values of growth and yield attributes per plant, but yield per unit area was higher with higher plant densities [5]. The reasons for decreasing productivity are due to decreasing soil fertility especially micronutrients, imbalanced use of fertilizer and occurrences of physiological disorders like square dropping, square drying, leaf reddening etc. Among these, imbalanced use of major and micro nutrients is the major problem [6]. To overcome these constraints, additional nutrition through foliar feeding is required over and above the normal fertilizer recommendation. This is one of the most efficient ways of supplying essential nutrients to a growing crop. Newly released, high yielding transgenic cotton cultivars are said to have a higher nutrient demand during the boll development period (between flowering and maturity) due to their higher boll retention rate and larger boll load than conventional cultivars [7].","PeriodicalId":411017,"journal":{"name":"INTERNATIONAL JOURNAL OF FORESTRY AND CROP IMPROVEMENT","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115429983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The trial was laid out with different spacing regimen as per statistical design. The growth observations were recorded at different intervals of time viz., 42, 45, 48 and 51 months after planting. The results revealed significant difference among different planting densities and maximum was recorded in planting density of 714 trees/ha (46.85 cm, 10.59 m; 50.14 cm, 10.99 m; 52.99 cm,11.22 m and 55.76 cm,11.43 m) for both girth (cm) and height (m), respectively for all the time interval. However, the total stand volume (m 3 /ha) in all the time interval was significantly superior in case of planting density of 2500 trees/ha (125.00 m 3 /ha, 148.33 m 3 /ha, 165.83 m 3 /ha and 189.25 m 3 /ha). Based on the results of the present experiment it is concluded that, the planting density of 2500 trees/ha exhibited significant stand volume compare to other planting density.
