Soybean yield may be affected in Bundelkand region of M.P.

The farmers of Bundelkhand region was generally sown soybean around 1-2nd week of July, 2015. Now the soybean crop is in flowering stage or will going to inter inR1 (first flower stage) stage during this week (17-23th August, 2015). Crop establishment was fair and till now the crop growth is good. Means the crop has undergone very little environmental stress and successfully entering into reproductive stage. May be stress will be started from now.
The high air temperature is around 32-33°C, but leaf/canopy temperature of Soybean may be higher than the air temperature.
The region received less rainfall (35 % less from Normal rainfall) from their normal value upto 15th August, 2015.
If the rest of the August month received less rainfall than seed number /meter square will be less and seed size will be also affected by low soil moisture, high evapotranspiration rate  and high air temperature( above 34°C).
There is white fly , green semi looper, Griddle B  attack on soybean crop. The cultivar JS 335 has been affected by YMV and more or less the cultivar JS 95-60. If warm temperature prevails further for next one-two weeks, substantial yield loss may occur, which may range from 20-40 % for rainfed conditions. The lower CGR rate, lower N fixation rate, and lower seed number and seed size may play the critical role.

Could foliar liquid nitrogen spray and weekly irrigation may help?  Suggestions invited from agricultural scientists.

अगस्त माह के शुरुवात में हो रहे ओस व कुहरा की घट्ना कहीं खुसे का संकेत तो नहीं बता रहे है

टीकमगढ़ में 6,7 व 10 अगस्त को ओस व कुहरा (कम) रहा। इतनी जल्दी ओस व कुहरे का आगमन शायद पहली बार देखा जा रहा है। पिछले 3 दिनों से उमश ने बुरा हाल कर दिया है। खण्ड़ बर्षा ने  किसानों के उमीद पर पानी फेर दिया है ऐसे हालात  किसी को भी गड़बड़ झाला  में डाल सकते है।
इस साल के मांसून से ज्यादा वर्षा बुन्देलखण्ड में शायद नहीं होगी । सुखे के संकेत लग रहा है , सोयाबीन के उत्पादन में कमी की उमीद प्रबल हो रहे है।
मुंग ,उर्द भी बीमारे से ग्रस्त है  अब तिल पर ही भरोसा है।

Rainfall and Black insect activity in Bundelkahnd region

The normal rainfall of 1st June to 8th August is 471mm and the Tikamgarh district received only 63 percent of normal rainfall so far. Hence rainfall during August will be very crucial for crop production.
The district normal rainfall during august is 343 mm and during august, till now the district received 10 percent of normal rainfall of august month. If the rainfall in august is also below 30-40 percent of the normal than Soybean productivity will be severally affected.
The black insect with bad smell have finally arrived on 5th August, 2015 and continued their activity in absence of heavy rain and continuous cloudy conditions. Their appearance normally coincides with flowering of soybean. This is also flowering started in soybean sown on 30 June- 3 July.

Generally the large number of insects appears in less rainfall year and vice-versa.

YMV infection in Soybean started in Bundelkhand

The disease YMV infected Soybean in Tikamgarh during last week of July,2015. The YMV first infected a weed and than the soybean crop. The cultivar JS 335 is infected first, though the infection is very low, but due to high night temperature (above normal) and dry period is suitable for its further growth on other healthy plants.

The rainfall activity during last week of July was almost very low ,only scatter rainfall at few place, this may be the reason for its growth.

May be some rain in next two-three days which will checked its growth.

Moreover, farmers have to only keep watch on the disease growth.
