The present investigation entitled "Performance of different coriander varieties for seed yield" was carried out during rabi season of the year 2013 at the College of Horticulture, Akola. The study consisted of eight coriander varieties using randomized block design and each treatment was replicated thrice. The varieties viz., Hissar Sugandh, Pant Haritima, Sadhana, Swati, CO 4, Hissar Anand, CO 2 and Rajendra Swathi were studied under investigation. The results revealed that variety Pant Haritima was found superior in seed yield (13.33 q/ha) but required more number of days for seed harvesting (131d). The yield contributing parameters like days required for seed harvesting, plant height; leaf area (73.9), number of umbels (20.5), number of umbellate (5.7), number of seed (30.4) and test weight (12.23 g) were observed with maximum numerical values in variety Pant Haritima, than rest of the varieties under study. Amongst the eight coriander varieties , Pant Haritima performed better in almost all the characters. Hence, this variety can be included in further breeding programme for improving the seed yield.
This research was conducted to investigate the "Effect of pinching and nitrogen on flowering and flower quality of annual chrysanthemum" was carried out during rabi season of the year 2019-2020 at the farm of Horticulture Section, College of Agriculture, Nagpur. The experiment was laid out in Factorial Randomized Block Design with 12 treatment replicated thrice. The treatments comprised of the three pinching treatments viz., no pinching, 20 DAT and 30 DAT and four nitrogen levels viz., 0 kg N ha -1 , 50 kg N ha -1 , 100 kg N ha -1 and 150 kg N ha -1 . The results obtained in the present investigation indicated that, the flowering parameters in terms of days to first flower bud initiation is recorded the minimum days in no pinching and no fertilizer treatment whrere as the maximum days to fully opened flower from bud initiation, days to 50 % flowering, days required for harvest and flowering span of plant was recorded maximum in pinching at 20 DAT and 150 kg N ha -1 . In respect of flower quality parameters the maximum weight of fully opened flower, diameter of fully opened flower, number of petals flower -1 , flower longevity and shelf life of flower were recorded in pinching at 20 DAT and 150 kg N ha -1 .
In order to estimate the response of banana to potash levels and split applications on the vegetative growth of banana, present investigation was conducted at Central Research Station (CRS), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2012-2013. For the investigation nine treatment combinations comprising two factors and three replications in FRBD design were used. The two factors are levels of potash and splits of potash. The results of investigation, indicated that, among three levels of potash, the level of potash with 350 g K/plant recorded maximum plant height, girth of pseudostem, number of leaves and leaf area. In respect of splits of potash, plants which were given three splits of potash showed maximum girth of pseudostem, number of leaves and leaf area. Thus, the plants given 350 g K/plant in three splits showed maximum vegetative growth.
Mandarin (Citrus reticulata Blanco) is a promising fruit crop gaining popularity for its human nutrition and economic importance in the world. The qualitative losses during pre-harvest stage hinder the quality production. Recently sunburn is major problem caused due to 'October heat', high temperature and direct solar radiation, which leads to significant economic losses in mandarin yield. So, a field experiment was conducted during 2017 and 2018 seasons at AICRP on Fruits (Citrus) Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. An experiment was conducted to assess the effect of foliar spray of chemical substances 3% and 5% of Kaolin and MgCO3 with combination of urea 1% and GA3 15 ppm with respective treatments twice in month of September and October on sunburn percentage and fruit quality of mandarin. The obtained results showed that, GA3 15 ppm+ urea 1% and kaolin 5% foliar applications were effective to control fruit sunburn as well as reducing severity percentage of sunburned fruit as compared to untreated trees. Moreover, Kaolin foliar application at two times was decreased leaf and fruit surface temperature especially at the concentration of 3% and 5%. Therefore, it could be recommended that, spraying kaolin at 3% and 5% two times in month of September and October, because it had a positive effect on preventing fruit sunburn damage and improvement marketable yield of mandarin trees.
