Weeds constituent one of the major economic important problem for maize growers and it can reduce yield up to 86 per cent. The magnitude of losses largely depends upon the composition of weed flora, period of crop-weed competition and its intensity. The highest weed control efficiency with lowest weed density and weed dry weight was noted in pre-emergence application of atrazine @ 1.0 kg a.i. ha -1 followed by (fb) one hand weeding (HW) at 30 DAS.

We describe a protocol for quantum information splitting (QIS) of a restricted class of three-qubit states among three parties Alice, Bob and Charlie, using a pair of GHZ states as the quantum channel. There are two different forms of this three-qubit state that is used for QIS depending on the distribution of the particles among the three parties. There is also a special type of four-qubit state that can be used for QIS using the above channel. We explicitly construct the quantum channel, Alice's measurement basis and the analytic form of the unitary operations required by the receiver for such a purpose.

In this correspondence, we point out a major security problem in the secret sharing scheme proposed in QIC 12(3-4), 0253-0261, 2012.
