Embodiment 1

[0065]In May 2019, a study was conducted using corn on a farm located in Texas, USA. Previous studies conducted by the inventors have shown that greater fertilization success can be achieved at time points outside the time when plants naturally release pollen, where fertilization occurs only during the morning time window. This experiment was designed to test the productivity of pollination performed over a 24-hour period while closely tracking changes in various environmental conditions. These conditions include temperature, humidity, wind speed, vapor pressure, vapor pressure differential, sun intensity, and UV intensity.

[0066] Processing is performed every two hours from 8pm (20:00) of one day to 10pm (22:00) of the next day. Each treatment was repeated 3 times, and each treatment had 12 spikes. Repeat in different rows to eliminate interference from field variations. Silks were selected prior to pollination to ensure plants were at a similar point of development. Th...

Embodiment 2

[0073] During 2019 and 2020, a series of 11 experiments similar to those outlined in Example 1 were conducted on maize plants in various locations, including Iowa, Texas, and Puerto Rico. The experiments were carried out at different times of the year, but in all cases the environmental variables were measured throughout the experimental period. These variables include: temperature, humidity, wind speed, gust speed, dew point, wind chill, wind direction and barometric pressure readings. Also, watch for precipitation. Calculate the vapor pressure difference over the time frame of the entire experiment. Fresh pollen or preserved pollen or both were applied to target corn plants at different time points over a set period of time and kernel counts were obtained for the resulting ears of corn. The experimental protocol was essentially as described in Example 1.

[0074] These experiments were performed to demonstrate factors such as temperature, relative humidity and vapor press...

Abstract

A method of identifying a selected pollination window of a gramineous crop by monitoring one or more environmental parameters and identifying the selected pollination window based on the monitored parameters. The correct selection of parameters has demonstrated to be able to significantly increase setting rate, yield, and / or other desirable characteristics, including but not limited to the preferred content of oil, starch, protein, and / or other nutritional ingredients. The parameters may include one or more of temperature, relative humidity, and vapor pressure difference.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 894,354, filed August 30, 2019, entitled Method and System for Optimizing Pollination Timing in Poaceae Crops. The entire contents of US Provisional Patent Application No. 62 / 894,354 are incorporated herein by reference. [0003] field of invention [0004] The present invention generally relates to techniques to allow and / or achieve improved yield by identifying a selected pollination window of time for pollination. More specifically, the invention relates to identifying a pollination window based on one or more of a series of measurable and / or monitorable parameters, and optionally to additionally using pollen to pollinate a plant at said selected time, and A method directed to identifying a plant's readiness to receive pollen at said selected time, and further to a method of releasing pollen at one or more selected times based on said serie...
