ABSTRACT: An experiment was conducted at Karda-Rasha /College of Agriculture-Erbil to evaluate the effect of different seeding rates using drill-row and broadcasting sowing methods on growth, seed and oil yields of rapeseed (Brassica napus L.) cv. Pactol. The results showed that drill-row sowing method produced seed and oil yields more than broadcasting method, particularly, at low seeding rates i.e.4 kg ha -1 seeding rate. Seeds grown by drill-row produced the highest number of plants m-2, the highest plants height and took the longest period for their flowering and seed formation; and produced a greater number of siliques plant-1 and greater weight of seed and then, higher seeds and oil yields. Seeds grown at higher seeding rates gave the higher number of plants m-2 and higher silique surface area, with longest period for seed formation, the highest plants height bearing higher number of primary branches, higher harvest index and high oil percentage. However, seeds grown at low seeding rates, the period from sowing to flowering and flowering period were the longest. At 4 kg ha-1 seeding rate produced higher number of siliques plant-1, greater weight of seed and higher seeds and oil yields. In this study, there was significant and positive correlation between number of siliques plant-1and seed weight with total Yield. While there was a significant and negative correlation between harvest index and total yield. Also, positive and highly significant correlation between oil yield and total yield.

ABSTRACT: Despite the undoubted success of a scientific approach to pharmaceuticals, the last few decades have reformed towards the spectacular rise in interest in herbal medicinal products for cure of livestock by the indigenous people of Hamirpur (H.P.), India. The present study was carried out between 2008 to 2011.Recording of indigenous medicinal plants used for common diseases in animals along with the interviews with elderly persons, cattle owners, traditional farmers, healers and house wives was done. A total of 123 plant spp. belonging to 49 families wild in occurrence, were reported to be used in more than 60 ailments of livestock. Low cost and almost no side effects of these medicines make them acceptable by the local community. Ethnomedicine is an integral part of traditional medical practices in many countries of the developing world. Livestock is a major asset for resource poor small farm holders and pastoralists throughout the world. The present study is aimed at providing an overview of the ethnoveterinary preparations for various ailments of livestocks particularly in Hamirpur District of Himachal Pradesh.

ABSTRACT: In a study conducted during 2007 and 2008 on irrigation and weed management effect on aerobic rice, scheduling the irrigation with IW/CPE of 1.2 produced significantly higher stature of yield attributes viz., total number of panicles m-2, total number of grains and number of filled grains and grain (4702 and 4547 kg ha-1) and straw yield and were distinctly superior to IW/CPE of 0.8 and 1.0. The nutrient uptake (nitrogen, phosphorus and potassium) by crop was also significantly highest with IW/CPE of 1.2.Weed management practices exerted significant influence on yield attributes, yield (5761 and 5595 kg ha-1), nutrient uptake by crop and all of them were at their highest with hand weeding at 20 and 40 days, which were comparable with oxadiargyl 0.07 kg ai ha-1 supplemented with hand weeding at 40 days. All the yield attributes and yield of rice were the lowest with unweeded check. Nutrient uptake by weeds was significantly highest with IW/CPE of 1.0 and among weed management practices with hand weeding at 20 and 40 days. Highest returns and benefit-cost ratio were recorded with the irrigations scheduled at IW/CPE ratio of 1.2 and with pre emergence application of oxadiargyl 0.07 kg ai ha-1 supplemented with hand weeding at 40 days.
