The experiment was laid out in split plot design with sixteen treatment combinations of main and sub plots, replicated trice. Four Dates of sowing viz. D1: 25th October, D2: 10th November, D3: 25th November and D4: 10th December were arranged in main plot and four planting geometries viz., S1: 30 x 5 cm, S2: 30 x 7.5 cm, S3: 30 x 10 cm and S4: 30 x 12.5 cm were taken as subplot treatments. Results revealed that coriander sown on 25th October registered significantly yield attributing characters viz., number of Original Research Article

Rapeseed mustard accounts for approximately 80% of all rabi oilseed production Currently, rapeseed cultivation accounts for less than 1% of the total area of rapeseed mustard in India. Weather is a very important factor among various abiotic stressors that affect crop growth and yield. Therefore, the plant response is greatly influenced by changes in the growing environment such as sowing date, rainfall, and temperature. Weather parameters play an important role in determining plant growth development and yield as the physical expression and various metabolic processes of a plant's genetic potential are strongly influenced by environmental factors. Rape blossoms are usually sown from mid-October to mid-November. Under multiple cropping systems after transplanting winter rice, the sowing time is usually from mid-November onwards. The thermal unit increased up to 120 DAS and decreased slightly upon matu...

The crop was sown manually on seedcum fertilizers 1 July 2021 and 2 July 2022 after the onset of monsoon. The result of the experiment revealed that, different weed management practices on seed yield, straw yield, harvest index % and economics of different herbicide application of ragi reveals that T9: Green manuring up to 40 DAS required highest cost of cultivation (Mean viz., 39676Rs. ha-1) than hand weeding twice 20 and 40 DAS (Mean viz., 34876Rs. ha-1) and lowest cost of cultivation in control (Mean viz., 22876Rs. ha-1). Gross return, net return and B: C ratio was significantly higher under (T5) Pyrazosulfuron ethyl 10 % 20...

along with a lack of high yielding varieties, abiotic and biotic stressors. Drought (lack of water),
overwatering (waterlogging/flooding), extreme temperatures (cold, frost, and heat), etc, all
negatively impact crop and other plant growth, development, yield, and seed quality. Drought or
moisture stress is the most important factor affecting upland rice under changing climate. Global
climate change also exacerbates the vulnerability of upland rice production. Upland rice plants
undergo physiological and biochemical alterations as well as morphological changes as a result of
moisture stress. Different moisture stress affects the yield of upland rice ranging from 18-97% yield
loss. As a result, crop management with broad, integrative and multi-disciplinary methodologies is
required to increase productivity and profitability. Different mitigation strategies to overcome
moisture stress and increase upland rice yields have been addressed in this review.

The field experiment was laid out with Indira Kodo 1 variety as test crop in Randomized block design (RBD) with 10 treatment and 3 replications. Results of the experiment revealed that, different weed management practices affected all the yield attributes and yield viz., Number of Ear Head, Length of Ear Head (cm), Number of Seeds Ear Head, Ear Head Weight (g), Test Weight (g), Harvest Index (%) and were significantly higher under Pyrazosulfuron ethyl 10 % 20 g/ha (PE) fb Chlorimuron ethyl 10 % + Metsulfuron methyl 10 % 4 g/ha (PoE) which was followed by Hand weeding twice at 20 and 40 DAS. All the yield attributes and seed yield were equally highest in both the kharif seasons i.e. seed and straw yield of kodo (Mean viz., 2044 and 4073 kg ha-1) were also found maximum under the treatment Pyrazosulfuron ethyl 10...

India is the second largest producer of litchi in the world after China. Presently in India, litchi is cultivated in an area about 99170 hectares with total production of 737200 metric tons and productivity of 7.43 metric tons / hectare. Chhattisgarh produces nearly cultivated in an area about 8474 hectares with a total production of 58907 metric tons and productivity of 1.94 metric tons / hectare. It is mainly cultivated in the old district of Surguja, Jashpur, Balrampur and Surajpur. The study revealeds that the growth rates in area, production and productivity was negative and found to be -0.02 %, -0.04 % and -0.02 % respectively in India while, in Chhatisgarh it was recorded -0.05%, -0.05%, and -0.003% In Jaspur district, it was noted to be -0.06%, -0.04%, and 0.01% respectively.

The variety used was Aiswarya (PTB 52). The yield attributes and yield viz., number of productive tillers m-2 , weight of panicle, number of spikelets panicle-1 , number of filled grains panicle-1 , grain yield, straw yield and harvest index were favorably influenced by treatments. Application of 30 kg P205 ha-1 and 120 kg N ha-1 through 50% N as CF, 25% N as FYM and in situ green manure cowpea (T5) recorded the maximum yield attributes and yield except number of spikelets panicle-1. The treatment T5 recorded maximum grain and straw yields of 3357 and 4133 kg ha-1 respectively and was on par with T6 and superior to other treatments. The maximum HI of 0.45 was recorded by the treatments T5 and T6.
