Various Kharif onion genotypes including one check Agrifound Dark Red were evaluated to study the path coefficient analysis for twelve different characters. In the present investigation, average weight of marketable bulb/plant has been considered as dependable variable with the other traits. Here both genotypic path as well as phenotypic paths have been discussed. The analysis had revealed that fresh weight of bulb (0.756) is the most important contributing trait followed by polar diameter(0.156), marketable yield(0.084), plant height 120 DAT (0.0753) leaves per plant 90 DAT(0.070), TSS(0.038) and days to harvest(0.028). These all characters had highest positive direct effect on average weight of marketable bulb. Hence, more emphasis should be given to these traits while selecting the genotypes for increasing the average weight of marketable bulbs of these onion genotypes.

Experiments were conducted on Ocimum basilicum with five levels of nitrogen (0,40,80, 120 and 160 kg per ha) and four levels of sulphur (0,30, 60 and 90 kg per ha) in a split plot design with three replications during rainy seasons 2011-12, 2012-13 and 2013-14. Nitrogen and sulphur application delayed onset and transition of phenological stages of French Basil except secondary and tertiary branching and 50% flowering. Nitrogen up to 120 and sulphur application up to 60 kg per ha noticed delayed primary branching, floral initiation, first fruit maturity, physiological and physical maturity. Response of nitrogen in increasing percentage accumulation of aromatic oil in Ocimum was positive with each increase in nitrogen and sulphur dose up to 80 and 90 kg per ha respectively during all growth stages with their maximum essential oil of 0.020 %.120 kg nitrogen /ha was the most responsive dose to get the maximum essential oil yield of 185 kg per ha which was 74.69 % more as compared to aromatic oil yield (105.90 kg per ha) when no nitrogen was applied. Nitrogen beyond this dose did not increase oil yield but instead decreased. Hence nitrogen above 120 kg per ha is detrimental effect on essential oil yield in Ocimum crop. Sulphur application also proved beneficial up to their maximum dose of 90 kg /ha in enhancing essential oil yield. The maximum aromatic oil yields of 32.00, 64.00, and 200.00 kg per ha respectively was recovered during 30, 60 and 90 days after transplanting with 90 kg sulphur applied to crop.

In order to evaluate the relationship between morphological characters in rice cultivars, two populations at F2 generation were examined. Statistical analysis on fifteen biometrical or quantitative characters were studied for estimating descriptive statistics, genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), genetic advance and heritability (Broad sense). Maximum standard deviation for total number of spikelets per panicle and total number of filled grains per panicle were recorded for both the crosses. Highest PCV and GCV was observed for panicle exsertion, total number of filled grains per panicle in ASD 16 x Kavuni (Cross I) and productive tiller in Swarna Sub 1x Kavuni (Cross II). Difference between GCV and PCV was low in most of the characters studied. High estimates of heritability and genetic advance were observed for flag leaf width for both the crosses. Both positive and negative skewness was observed for different traits, while platykurtic distribution was observed for most of the traits in F2 populations of two crosses.

Vegetative and reproductive phenological behaviour of Erythrina variegata and E. subumbrans were studied in two distinct precipitation regimes of tropical forest (Neihbawi and Sairang) of Mizoram, North East India. Phenological variables such as timing and date, onset, duration, synchrony and amplitude were recorded and derived by following standard methodology. Hypothesis related to phenological pattern of tropics were examined in current study. Leaf fall in is mainly coincided with dry season while leaf flush is overlapped with early rainy season in both the studied species. Flowering in E. variegata is occurred during end of dry season while in E. subumbrans it exhibited during peak rainy season. Fruiting in E. variegata is coincided with early to peak rainy season while in E. subumbrans it occurred during dry season and cool climatic conditions. This study supports differential flowering and fruiting timing among related genera, which might be important to avoid competition for pollinators and driving factor for high faunal diversity in tropics. Thus, this study is rigging the hypothesis that the evolutionary limitations are more reliant than the local environment and biotic conditions.

Rainfall data of 19 years (1979-2015) of Mayurbhanj district were analysed whose annual average rainfall is 1808.2 mm, with 100 numbers of rainy days, to determine the sowing period, seasonal distribution of rainfall and probability of receiving particular amount of rainfall in a week, month and season . Out of this 292.3, 1397.27 and 292.3 mm is received in pre-monsoon (January-May), monsoon (June-September), and post monsoon (October-December) season respectively. Probability for receiving more than 100 mm of rainfall can be expected even at 90% probability level in the month of June leading to the interpretation that rainfed rice can be taken in the district without any risk. It has been found that at 70 per cent assured probability level rainfall of more than 350 mms can be expected in July and this rainfall can be utilised in medium to lowland paddy areas for transplanting of paddy. On seasonal basis, rainfall at assured probability level of 75% the expected rainfall is 1260.6 mm, which is sufficient for meeting the water requirement of medium to long duration rice variety.
