Several ill effects in soil and human health as well as environmental hazards were noted due to the use of imbalance nutrient application. Nutrient management is necessary to balance the soil nutrient input with the crop requirement. Therefore, the field experiment was conducted during the kharif and rabi seasons of 2020-21 and 2021-22 at Research Farm of ICAR-CPRI-RS, Gwalior, to examine the interactive effects of organic mulch and different nutrient sources on productivity and profitability of rice - potato cropping system. The experiment was conducted in randomized block design with three replications. The treatment combination consisted of two factors such as mulch (No mulch and paddy straw mulch @5 t/ha) and different sources of nutrients (100% RDF, Compost @25 t/ha + Azotobacter @1.25 l/ha + PSB @1.25 l/ha + Jeevamrut @500 l/ha, FYM @25 t/ha + Jeevamrut @500 l/ha and control). Results revealed that, application of paddy straw as mulch @5 t/ha significantly resulted in the highest grain (2.73 t/ha) and straw (5.52 t/ha) yield of rice, tuber and haulm yield of potato (23.48 t/ha and 10.38 t/ha, respectively) and net return (2,54,975 ₹/ha). Among various nutrient sources, application of 100% RDF significantly recorded the highest grain yield of rice (3.81 t/ha), tuber and haulm yield of potato (26.43 t/ha and 12.55 t/ha, respectively) as well as improved the system productivity as compared to all other treatments but maximum net return (2,76,630 ₹/ha) obtained under FYM @25 t/ha + Jeevamrut @500 l/ha.
The present investigation in titled “Effect of growth regulators and vermicompost on female flower in bottle gourd [Langeraria sicenaria (mol.) standl.]’’ by Growth Regulators” at the Horticulture Research Farm, R.A.K college of Agriculture, Sehore (M.P.) during 2019-20 and 2020-21. This experiment was laid down in Randomized block design with three replications. The thirteen treatments viz., T1 (GA3 0 ppm + Vermicompost @ 0), T2 (GA3 25 ppm + Vermicompost. @ 2 t/ha), T3 (GA3 50 ppm + Vermicompost @ 4 t/ha), T4 (GA3 75 ppm + Vermicompost @ 6 t/ha) T5 (Etherel 100 ppm + Vermicompost @ 2 t/ha.), T6 (Etherel 200 ppm + Vermicompost @ 4 t/ha.), T7 (Etherel 300 ppm + Vermicompost @ 6 t/ha.) T8 (NAA 100 ppm + Vermicompost@ 2 t/ha.), T9 (NAA 150 ppm + Vermicompost @ 4 t/ha.), T10 (NAA 200 ppm + Vermicompost @ 6 t/ha.), T11 (CCC 200 ppm+ Vermicompost @ 2 t/ha.), T12 (CCC 400 ppm + Vermicompost @ 4 t/ha.) and T13 (CCC 600 ppm + Vermicompost @ 6 t/ha.) were evaluated during the experiment. The maximum days taken to first female flower were recorded under the treatment T1 (61.33 in 2019-20) and (62.00 in 2020-21). While the minimum days taken to first fruit picking significantly recorded under the treatment T6. In relation to sex ratio, the maximum sex ratio of flowers recorded under the treatment T1 (11.67 in 2019-20) and (10.83 in 2020-21. While the minimum sex ratio of flowers v experiment the treatment T6 found superior compare to control treatment.
The present investigation on the population dynamics of thrips and bud necrosis disease on tomato crops (cv. Arka Vikas) was carried out during two consecutive crop growing seasons of Kharif, 2016 and 2017. Results revealed that there were two thrips species (Thrips palmi Karny and Scirtothrips dorsalis Hood) that occurred together at different crop growth stages and the population was high during the flowering stage (5.25 to 9.35 thrips/top three leaves), which later started to decline at crop maturity. The symptoms of bud necrosis disease started appearing after 3rd week of transplanting and increased gradually with necrosis symptoms on terminal buds followed by necrotic streaks on petioles and stems, leading to the complete collapse of the plants. The cumulative disease incidence was 43.80 % at the harvesting stage. Correlation analysis with the weather parameters indicated that rainfall and relative humidity exhibited a significant negative correlation with the thrips population and associated bud necrosis disease. While, the correlation of the miridbug, Nesidiocoris tenuis population, was linear with the thrips population and found throughout the cropping period.
The present study was conducted in Raisen district of Madhya Pradesh during 2020-21 at the school of Agriculture sciences BRAUSS Mhow, M.P. The main objective of the present research was to study the decision making pattern of farm women related to horticultural crops production. For this study 180 randomly selected farm women were taken as a sample from study area. The study revealed that majority of the farmwomen belonged to medium decision making pattern related to horticultural crops production followed by low and high decision making pattern of horticultural crops production respectively.
A crop regulation study was carried out on six- seven year old orchard of guava cv. G-27 during 2020-2021 and 2021-2022 to evaluate the effect of different crop regulation methods on reproductive characteristics. The experiment was laid out in Randomized Block Design comprised of 16 treatments with 3 replication consisting of foliar spray of KI (0.5 %, 0.75 % and 1.0 %), NAA (400 ppm, 600 ppm and 800 ppm), Ethephon (600 ppm, 1200 ppm and 1800 ppm), bending of lateral branches with partial removal of old leaves (mid-April, mid-May and mid-June) and shoot pruning (up to 15 cm, up to 30 cm and up to 45 cm) with complete removal of old leaves and water spray as control. The result showed that all the treatment were significantly effective in summer deblossoming for avoiding rainy season crop and induce profuse flowering and fruiting during winter seasonin both the year as well as pooled data over to control. Among the treatments, foliar spray of NAA 800 ppm was recorded significantly maximum number of buds per plant (483.83), number of flowers per plant (431.36), fruit set (75.92 %), fruit retention (50. 94 %)and minimum bud drop (10.85 %) and flower drop (49.06 %), which was at par with bending of lateral branches with partial removal of old leaves in mid-June as compared to other treatments in pooled data. In case of minimum days taken to initiation of flower bud (39.67 days) was recorded significantly result under treatment of bending of lateral branches with partial removal of old leaves in mid-June followed by bending in mid May as compared to other treatments during pooled analysis.
