Background: Pulses play an important role in Indian agriculture and they are the rich sources of protein. Redgram is an essential food legume, mostly cultivated under rainfed condition in India. Due to increasing population the demand of pulses is increased; hence the redgram productivity has to be increased to meet out the requirement. To overcome this problem an investigation was carried out to study the effect of crop geometry, modified canopy architecture and 1% PPFM application on morpho-physiological and biochemical responses of rainfed redgram during north-east monsoon season. Methods: The treatments comprised of varied crop geometries viz, broad casting (farmer’s practice), high density planting at 30 × 30 cm and recommended spacing of 60 × 30 cm; modified canopy architectures viz. nipping of primary branches at 45 and 60 days after the receipt of soaking rain and foliar application of 1% PPFM spray at 50% flowering to avoid the moisture stress. Result: The results revealed that sowing at 60 × 30 cm spacing with nipping at 45th day recorded significantly higher seed yield and protein yield of redgram in rainfed condition. Further, nipping at 45th day showed higher level of relative water content (51.6%) associated with lower level of proline (26.61 mg g-1).

Background: Redgram is an important food legume which is largely cultivated under rainfed condition. In India rainfed agriculture contributes 80% of the total pulses production and the projected requirement will be 39 million tons by 2050 which necessitates an annual growth rate of 2.2%. The productivity has to be increased from the present level of 834 kg ha-1 to 1200 kg ha-1. With adoption of suitable agronomic management strategies the productivity could be increased to meet our demand and achieve self sufficiency in production. Hence the current study was carried out to increase the productivity of redgram under rainfed condition.Methods: Field experiment was conducted in farmer’s field in Madurai district, Tamil Nadu during North East Monsoon season of 2019 to study the effect of improved agronomic manipulations on growth and yield of redgram under rainfed ecosystem. Agronomic management approaches viz., nipping of primary branches at 45 and 60 days after receipt of soaking rain, high density planting at 30 cm × 30 cm in addition to recommended spacing of 60 cm × 30 cm and foliar application of 1% PPFM spray were compared with farmer’s practice in the redgram variety Co (RG) 7. Pre monsoon sowing has been taken up and the rainfall received during the cropping period was 521.7 mm received in 31 rainy days.Result: The field experimental results revealed that adoption of agronomic manipulation at the appropriate stage of the crop has increased the productivity of redgram. Nipping of primary branches at 45th day of the crop significantly increased the total number of productive branches, number of pods plant-1 and recorded the maximum seed yield of 1512 kg ha-1 (72 per cent increase over farmer’s practice) under rainfed condition.

Actual Contribution

Two desiderata in Medieval Studies continue to be rather troublesome because they have not been tackled effectively by many scholars. First, most of us are not familiar with medieval Welsh language and literature; second, we are still rather uncertain about the actual contribution by women to medieval poetry, for instance. But our Welsh colleagues have already determined for quite some time that the late medieval Gwerful Mechain was a powerful voice and offered many intriguing perspectives as a woman, addressing also sexuality in a rather shockingly open manner. She was the daughter of Hywel Fychan from Mechain in Powys in north-east Wales. She lived from ca. 1460 to ca. 1502 and was a contemporary of the major Welsh poets Dafydd Llwyd and Llywelyn ap Gutyn. She might have been Dafydd’s lover and she certainly exchanged poems with Llywelyn. Not untypically for her age, which the present editor and translator Katie Gramich observes with strange surprise, Gwerful combined strongly religious with equally strongly erotic—some would say, pornographic—poetry. Gramich refers, for instance, to the Ambraser Liederbuch, where we can encounter a similar situation, but it seems unlikely that she has any idea what this songbook was, in reality (there are no further explanations, comments, or references to the relevant scholarship). She also mentions Christine de Pizan, who was allegedly “forced to take up the pen” (10), which appears to be a wrong assessment altogether. There is no indication whatsoever that Gramich might be familiar with the rich research on late medieval continental and English women writers, but this does not diminish the value of her translation.

Poplar clone Kranti was selected to assess the morphological, physiological and biochemical responses under drought at different levels of water stress, as it is a common clone used to be grown in Uttarakhand for making paper and plywood. The cuttings of Populus deltoides L. (clone Kranti) were exposed to four different watering regimes (100, 75, 50 and 25% of the field capacity) and changes in physiological and biochemical parameters related with drought tolerance were recorded. Alterations in physiological (i.e. decrease in relative water content) and biochemical parameters (i.e. increase in proline and soluble sugar content and build-up of malondialdehyde by-products) occurred in all the three levels of water stress, although drought represented the major determinant. Drought treatments (75%, 50% and 25% FC) decreased plant height, radial stem diameter, harvest index, total biomass content and RWC in all the three watering regimes compared to control (100% FC). Biochemical parameters like proline, soluble sugar and MDA content increased with severity and duration of stress, which helped plants to survive under severe stress. It was analyzed that for better wood yield poplar seedlings should avail either optimum amount of water (amount nearly equal to field capacity of soil) or maximum withdrawal up to 75% of field capacity up to seedling establishment period (60 days). Furthermore, this study manifested that acclimation to drought stress is related with the rapidity, severity, and duration of the drought event of the poplar species.
